Greenpeace investigation shows Fukushima radiation risks to last into next century

プレスリリース – 2018-03-01

Tokyo, 1 March 2018 – A comprehensive survey by Greenpeace Japan in the towns of Iitate and Namie in Fukushima prefecture, including the exclusion zone, revealed radiation levels up to 100 times higher than the international limit for public exposure.[1][2] The high radiation levels in these areas pose a significant risk to returning evacuees until at least the 2050’s and well into next century.

The findings come just two weeks ahead of a critical decision at the United Nations Human Rights Council (UNHRC) review on Japan’s human rights record and commitments to evacuees from the nuclear disaster.

“In all of the areas we surveyed, including where people are permitted to live, the radiation levels are such that if it was in a nuclear facility it would require strict controls. Yet this is public land. Citizens, including children and pregnant women returning to their contaminated homes, are at risk of receiving radiation doses equivalent to one chest X-ray every week. This is unacceptable and a clear violation of their human rights, ” said Jan Vande Putte, radiation specialist with Greenpeace Belgium and leader of the survey project.

Greenpeace Japan conducted the investigations in September and October last year, measuring tens of thousands of data points around homes, forests, roads and farmland in the open areas of Namie and Iitate, as well as inside the closed Namie exclusion zone. The government plans to open up small areas of the exclusion zone, including Obori and Tsushima, for human habitation in 2023. The survey shows the decontamination program to be ineffective, combined with a region that is 70-80% mountainous forest which cannot be decontaminated.

Key finding from the Greenpeace Japan survey:

  • Even after decontamination, in four of six houses in Iitate, the average radiation levels were three times higher than the government long term target. Some areas showed an increase from the previous year, which could have come from recontamination.

  • At a house in Tsushima in the Namie exclusion zone, despite it being used as a test bed for decontamination in 2011-12, a dose of 7 mSv per year is estimated, while the international limit for public exposure in a non-accidental situation is 1 mSv/y. This reveals the ineffectiveness of decontamination work.

  • At a school in Namie town, where the evacuation order was lifted, decontamination had failed to significantly reduce radiation risks, with levels in a nearby forest with an average dose rate of more than 10 mSv per year. Children are particularly at risk from radiation exposure.

  • In one zone in Obori, the maximum radiation measured at 1m would give the equivalent of 101 mSv per year or one hundred times the recommended maximum annual limit, assuming a person would stay there for a full year These high levels are a clear threat, in the first instance, to thousands of decontamination workers who will spend many hours in that area.

This contamination presents a long term risk, and means that the government’s long-term radiation target (1mSv/year which is equivalent to 0.23μSv/hour) are unlikely to be reached before at least the middle of the century in many areas that are currently open and into next century for the exclusion zone of Namie. In an admission of failure, the government has recently initiated a review of its radiation target levels with the aim of raising it even higher.

The Government’s policy to effectively force people to return by ending housing and other financial support is not working, with population return rates of 2.5% and 7% in Namie and Iitate respectively as of December 2017.

In November last year, the UNHRC’s Universal Periodic Review (UPR) on Japan issued four recommendations on Fukushima issues. Member governments (Austria, Portugal, Mexico and Germany) called for Japan to respect the human rights of Fukushima evacuees and adopt strong measures to reduce the radiation risks to citizens, in particular women and children and to fully support self evacuees. Germany called on Japan to return to maximum permissible radiation of 1 mSv per year, while the current government policy in Japan is to permit up to 20 mSv per year. If this recommendation was applied, the Japanese government’s lifting of evacuation orders would have be halted.

“Our radiation survey results provides evidence that there is a significant risk to health and safety for any returning evacuee. The Japanese government must stop forcing people to go back home and protect their rights,” said Kazue Suzuki, Energy Campaigner at Greenpeace Japan. “It is essential that the government fully accept and immediately apply the recommendations at the United Nations.”

[1] Reflections in Fukushima: The Fukushima Daiichi Accident Seven Years On

[2] The International Commission on Radiological Protection (ICRP) sets a maximum dose of 1 mSv/ year in normal situations for the public, and in the range of 1-20 mSv/y under post-nuclear accident situations, such as that resulting from Fukushima Daiichi. The ICRP recommends that governments select the lower part of the 1–20 mSv/year range for protection of people living in contaminated areas, and “to reduce all individual exposures associated with the event to as low as reasonably achievable.”

The truth concerning nuclear accident induced thyroid cancers. Japan TVreport

In Japan we see the nuclear industry fight back concerning claims of thyroid cancers using all the tools in their armories. Meanwhile, dedicated health professionals, activist groups and even a Nobel prize winner Professor Masukawa has challenged the Japanese Governments version of events and consequences.

In a recent Japanese television publication (Our Planet TV), a presentation of the effects in Chernobyl was made in Japanese and Belorussian with an English Power Point presentation. The presentation was from Victor Kondradovich from the Minsk Municipal Onocological Centre in Belarus.

The findings of this presentation shows the manipulation of the nuclear industry when it comes to reporting health issues after nuclear accidents. As many nuclear reactor and processing countries are trying to ease the allowable amounts of radioactivity we are allowed whilst playing down reported health effects.

An Taisce Ireland Welcomes Public Consultation UK Hinkley Point C, Nuclear Power Plant

“…..The estimates for compensation seem entirely unrealistic in the context of the costs incurred in Fukishima, and even then there is a significant shortfall to be met by a UK Government who will be struggling in the aftermath of a serious Nuclear event…..”

20th February 2018
Press Release

The Government has today launched public consultations on the UK’s Hinkley Point C, nuclear power station, 5 years after it should have under UN Conventions. The UK Government are building a nuclear power station, Hinkley Point C, on the north coast of Somerset, some 150 miles (~242 km) from Ireland’s East Coast.

Charles Stanley-Smith, An Taisce’s Communication Officer stated “These consultations have been hard won through court cases and escalation to the compliance committees of two UNECE conventions on consultation rights and obligations. This is the hard work of An Taisce, The Environmental Pillar and Friends of the Irish Environment and German MEP Ms Sylivia Kotting-Uhl”

He continued “The peoples’ rights to these consultations will become increasingly important in our ability to address transboundary impacts of UK projects on our environment, health and economy, into the future. Under UN Conventions, the peoples of neighbouring countries that could be affected by a project need to be consulted. Post Brexit, we may not be able to rely on EU law to safeguard us, but these are UN conventions For instance, the Irish people will now need to be consulted in terms of any other 5 proposed nuclear power station on the UK’s west coast”

Charles Stanley-Smith continued “An Taisce welcomes this Consultation and we would like like to encourage people to participate, in this consultation which is being organised through the Local Authorities across the country. The deadline for your submissions is 17th April 2018”

An Taisce challenged the planning permission and lack of transboundary consultation in the UK Courts [Note 1]. Then along with The Environmental Pillar and Friends of the Irish Environment, they continued their challenge through the compliance mechanisms of the relevant international conventions governing consultation on transboundary impacts. The committees responsible for compliance with the conventions have been robust in upholding the interests of the public.

Following the recommendations of one of these committees, a further round of consultation by the UK on Hinkley Point C happened between July and October last year. In those cases Germany, Denmark and the Netherlands facilitated their public being consulted. Irish eNGOs escalated their concern about the further failure by Ireland to provide for consultation during that period with the Irish public. This resulted in the committee writing to the Irish Government and invited Ireland to uphold the rights of the Irish public to be consulted. This is now finally happening in this extended round of consultation, commencing on Feb 20th, 2018. [Note 2]

We suggest some considerations the public could make in their submission:

  • The discounted economic loss to Ireland of an accident in a plant like Hinkley Point C being ‘conservatively’ estimated by the ESRI in a 2016 report [Note 3] as €161 billion ( scenario 4) ;
  • The serious deficits in the climatic modelling which the UK used in the UK’s assessment of the potential transboundary impacts in the event of an accident; [Note 4]
  • The lack of emergency response planning in Ireland to deal with such an incident to protect the public; The Radiological Protection Institute of Ireland, (RPII) in its 2013 report [Note 5] on the Radiological impacts of the proposed UK plants in Ireland, produced after the UK granted permission assumed the impacts to Irish people can be mitigated against by sheltering indoors, but fail to address basic considerations and practicalities of the feasibility of such mitigation given issues like the contamination of our largely uncovered water supply.
  • The effect on Ireland’s agriculture could be devastating. If an event was to occur in April for example when all the winter fodder is exhausted, new silage can’t be made, and animals would need to be kept inside without food or water. The extent of Insurance coverage in place in the event of an accident is also controversial. The estimates for compensation seem entirely unrealistic in the context of the costs incurred in Fukishima, and even then there is a significant shortfall to be met by a UK Government who will be struggling in the aftermath of a serious Nuclear event.
  • There are additional risks now consequent on Brexit. Currently we can rely on the controls associated with a number of EU Directives, and key EU principles regarding the polluter pays and the precautionary principal which underpin these directives set out in the EU treaties. Amendments are being drafted for the House of Lords debate on the Great Withdrawl Bill may or may not serve to adequately address these principals in the post-Brexit UK legislative codes. The extent of parliamentary oversight to changes in UK legislation post Brexit has already been acknowledged to be a hugely controversial issue, given the extent of powers being granted to amend legislation by regulation in the bill.
  • Also as part of Brexit the UK proposes to withdraw from the EURATOM treaty, which is concerned with a number of matters including Nuclear Waste and safety. The implications of this are entirely unclear.
  • Serious technical issues have become apparent with the design for the reactor pressure vessel proposed for use in Hinkley which have become apparent in Flamanville in France.

Notes

[1] History of Court Cases

  • Development Consent Order for Hinkley Point C was granted on 19th March 2013.
  • An Taisce on learning of the Secretary of State’s decision, mounted a Judicial Review challenge against the decision in the court of England and Wales, taking the matter all the way to the Supreme Court who ultimately ruled against.
  • An Taisce has sought a reference to the EU Court of Justice, (CJEU), to clarify the proper interpretation of Article 7 of the EU Environmental Impact Assessment Directive, (2011/92/EU) regarding the test for transboundary impacts, in light of the two UNECE Conventions which underpinned this article.
  • The UK Supreme Court refused the appeal on paper stating that the CJEU had already ruled on the matter.
  • Subsequently Friends of the Irish Environment, (FIE), supported by An Taisce made a complaint to the implementation committee of one of these conventions The UNECE Convention on Environmental Impact Assessment in a Transboundary Context” (the Espoo Convention),and also by a German Member of Parliament, Ms Sylivia Kotting-Uhl, and other complaints were also made to the Compliance Committee of the UNECE
  • These committees ultimately found the UK to be non-compliant with its consultation obligations in respect of Hinkley Point C.

[4] Professor John Sweeney’s Assessment

Professor John Sweeney assessed the assessment and reports the UK prepared under Article 37 of the EURATOM treaty and which the UK relied up on in determining its view on the potential for transboundary impacts from HInkley Point C in the event of an accident. Below he has provided a brief summary of his technical report, with a very stark and strong conclusion regarding the confidence on the competence of key elements of the Article 37 submission.

“Summary of Hinkley Concerns

  1. The risk of extreme meteorological events coinciding with an accident occurring at Hinkley are calculated on an unsound basis. The weather database used to estimate e.g. an event which might occur e.g. once in 10,000 years cannot be calculated with any confidence from the short run of data used by the Hinkley proposers. The statistical basis for this is further undermined by the fact that climate changes are currently underway in both the UK and Ireland which render reliance on a short historical climate database unsound.
  2. Similar concerns arise when calculating water levels at this coastal site. Existing tide gauges indicate sea level is rising all along the south coast of England. Current estimates are that sea level will continue to rise into the 22nd Century at least, with ultimate rises of several metres likely. The effect of this requires to be incorporated in any extreme water level calculation and certainly making estimates for the 1:10,000 year event is not statistically valid.
  3. Uncertainty exist as regards future storm surge changes. Combined with sea level rise this poses additional risks which are not handled using the precautionary principle by the Hinkley proposers. Water level considerations are crucial since spent fuel is to be stored for over a century at this coastal site.
  4. The dispersion model used dates from 1981 and several caveats to its use have been made by its original author. These caveats are particularly relevant to the site and situation of Hinkley Point and do not appear to have been considered adequately in the report.
  5. Any dispersion model based on progressive dilution downwind does not adequately consider meteorological conditions conducive to long range transport of a pollution plume in an undispersed state. Chernobyl exemplified this, resulting in serious implications for Irish upland farming. The worst case outcomes for Ireland are therefore not adequately considered in the dispersion modelling used.
  6. Ireland, unlike France and the Channel Islands, was excluded from any accident impact assessment. The Irish coast and the Channel Islands are equidistant from Hinkley and only slightly further than the nearest point on the French Coast. This raises issues of confidence about the extent to which the report can be considered competent. “

A new report on Sellafield highlights the likely nuclear damage to Ireland. Exclusive to nuclear-news.net

Conclusion to #Sellafield accident report 2017

The EPA 2016 report is unsafe and cannot be relied upon by the public, the media or administrators. The anonymous authors have shown extraordinary bias in every aspect of the report. They made elementary mistakes in their source term listing of isotopes, by including those which had short half-lives and will clearly not have been present in any significant concentration. They omitted a whole series of nuclides which are present in the tanks and the fuel pools. They choose a source term which is demonstrably too low based on available data, they choose a worst-case accident which involves only one HAST tank and only Caesium-137. They omit mentioning the spent fuel pools which are a highly likely site of a major coolant loss and subsequent fire or explosion. Their air modelling results are extremely unusual with implausibly narrow plumes, whilst a NOAA HYSPLIT model for the same day shows a completely different dispersion covering most of highly populated Ireland. Their surface contamination levels are 200 times lower than a previous computer model by Dr Taylor, which they must have had access to, and they fail to calculate the increased levels of cancer in the exposed population. This has been rectified here.

Historic releases from Sellafield to the Irish Sea have caused measurable increases in cancer and leukemia in coastal populations of Ireland. There is no doubt that the existence of Sellafield represents a potential catastrophic danger to the Irish Republic. A serious accident there could destroy the country and also most of Britain. As the Chernobyl accident effects showed, and the Fukushima accident effects will reveal (and in the case of Thyroid cancer have revealed) the ICRP risk model is unsafe for explaining or predicting health effects from such contamination. The Authors of the EPA 2016 report should be sanctioned in some way for producing such a travesty of the real picture, especially since they will have had access to the earlier study and modelling by Peter Taylor and the details of the COSYMA model employed by him.

Introduction by Shaun McGee (aka arclight2011)

Published exclusive to nuclear-news.net (Creative Commons applies)

2 February 2018

The Irish Sellafield nuclear accident fallout projection report has some issues, in my opinion.
In December 2016 the Irish Environmental Protection Agency (EPA) published in Irish Media Sources a report on radioactive fallout from a “worse case” scenario.
At the time, I was in contact with the Irish EPA concerning new evidence that shows a larger health effect from radiation sources and I was trying to challenge the pro nuclear bias that underestimated the health and environmental problems using mechanisms from the EURATOM nuclear treaty in Europe. I have to say that the Irish EPA were forthcoming in their many responses to my inquiries but eventually we reached a stale mate as the EPA claimed that the specific Isotopes relevant to the Euratom Treaty are not to be found in Ireland with the exception…

Cross-border nuclear cooperation must improve, Dutch watchdog warns

By Sam Morgan |

6 Feb 2019

Cross-border cooperation on nuclear safety between the Netherlands, Belgium and Germany leaves a lot to be desired, the Dutch Safety Board has concluded in a new report.

Although the report says that the chances of a serious incident are “small”, it warns that cross-border nuclear accident cooperation would “not run smoothly” and urges the authorities to improve contingency planning.

Belgium’s nuclear reactors have long courted controversy due to their age, well-documented safety concerns and their close proximity to the country’s borders with Germany and the Netherlands.

The Dutch Safety Board report looked into how well the three countries are working together on aspects like evacuation strategies, plant maintenance and contingency planning.

Its report highlighted that radiation treatment measures vary between the three countries. For example, Germany has issued iodine tablets to some border communities while towns on the other side of the borders go without. Evacuation plans also differ.

That is why the safety experts warned that without further measures, a potential nuclear accident “will not run smoothly” and could risk causing “confusion and unrest”.

The watchdog warned that public safety concerns must be addressed properly and more efforts should be made to communicate nuclear incident reports when they happen.

In its conclusions, the report also warns that the three countries have not taken linguistic and cultural differences fully into account, and urges the Netherlands to join a Belgo-German agreement on joint decision-making that was set up in December 2016.

German Environment Minister Barbara Hendricks has failed in her bid to get the ageing Belgian nuclear reactors of Doel 3 and Tihange 2 shut down permanently. Instead, Berlin and Brussels have agreed to a better exchange of information on all things atomic. EURACTIV Germany reports.

But the Safety Board did praise the efforts that have been made in some areas. All three countries now notify each other of an imminent emergency “as quickly as possible” and have access to each other’s radiation measurements.

The report did not examine the technical safety aspects of the nuclear plants involved, including Belgium’s Tihange and Doel facilities, as well as Germany and the Netherlands’ Borssele and Emsland power plants.

Both Tihange and Doel have given the authorities cause for concern after micro-fissures were found in some of the reactors. Reactors 2 and 3, respectively, of the power plants were shut down in 2013 to address the situation and were restarted in 2015.

Belgium’s government has been accused by anti-nuclear activists of endangering the safety of its citizens by extending the life of the reactors, which were only designed to have a shelf life of 30 years. That is because the country’s energy mix depends heavily on atom-smashing (40% of total energy needs and 55% of electricity comes from nuclear).

Interior Minister Jan Jambon insisted last June that the security of the power plants is not in doubt and they will continue to operate until their extended deadlines end in the mid-2020s.

Meeting of the International Independent Scientific Commission for investigation of Ru-106 case

work-idioms-2-mb-6-638

INSTITUTE NEWS

01.02.2018

Meeting of the International Independent Scientific Commission for investigation of Ru-106 case

Upon the initiative put forward by Academician Leonid Bolshov, Scientific Leader of the Nuclear Safety Institute of the Russian Academy of Sciences, and Corresponding Member of the Russian Academy of Sciences Viktor Ivanov, Head of the Russian Scientific Commission on Radiation Protection, an International Independent Scientific Commission for investigation of Ru-106 case in Europe in September-October 2017 (Ru-Commission) was established in December 2017.

The Commission represents an independent group of scientists and specialists from France, Finland, Sweden, Germany, Norway, Great Britain and Russia, whose members are professionals in the area of nuclear safety, transport modelling and emergency response.

The Federal Environmental, Industrial and Nuclear Supervision Service (Rostechnadzor) of Russia and the State Corporation “Rosatom” agreed to render an informational support for the Commission work.

The main objective of the Commission is to define the origin of the Ru-106 release and its possible effect on the population health.

The first meeting of the Commission was held on 31st of January, 2018, in Moscow, at IBRAE RAN premises.

In accordance with the agreed agenda, representatives of France (Mr. Jean-Luc Lachaume), Finland (Dr. Aleksi Mattila), Sweden (Ms. Katarina Danestig Sjögren and Ms. Anna Maria Blixt Buhr), Norway (Ms. Astrid Liland), Germany (Dr. Florian Gering), Russia (Mr. Alexey Kiselev, Dr. Konstantin Rubinstein and Dr. Viktor Ivanov) presented the results of measurements and findings related to the Ru-106 case in September- October 2017 to the Commission.

The Commission members discussed the presented information and agreed on the plans of the further Commission activity and communication of its results to the public.

The Commission members drew the following conclusions of the 1st Meeting:

  1.  Based on the measurements in different European countries and Russia, the entire activity of Ru-106 found in the air in between the end of September to the beginning of October, 2017, is estimated as ~ 100 TBq.
  2. Based upon the available data, no health effects are expected for the population.
  3. Modelling calculations performed in different countries are consistent with each other, though there are too many uncertainties to make conclusions about the location of the Ru source at the moment.
  4. In some countries, measurements of Ru-103 were made. The ratio of Ru-106/Ru-103 was the same and corresponds to a fresh spent fuel.
  5. The Commission needs to collect and verify all available data, to form a unified Database and assess the quality of the data. There is a need to request Roshydromet on the local weather conditions data and additional data on precipitation measurements.
  6. There is a need in additional measurements upward the wind direction from localities where Ru-106 was found in the Chelyabinsk Region. The Commission considers helpful to get measurements from Romania on deposition of Ru-106 due to the highest values of Ru-106 activity detected.
  7. The hypothesis on the “medical” origin of Ru-106 (as a source for medical therapy) can be excluded.
  8. According to Roshydromet data, a specific atmospheric phenomenon of descending air flow circulation was observed in the Chelyabinsk Region around the end of September. These data  shall be taken into account for further consideration.
  9. The Commission noted that the Rostechnadzor inspections were conducted at the PO “Mayak” and NIIAR (Dimitrovgrad) facilities covering the operations during the period August – November 2017, and no deviations from normal technological processes were found.
  10. The Commission agrees to work transparently and communicate the outcomes and conclusions to the public.
  11. The next meeting of the Commission is scheduled for April 11, 2018 in Moscow.

Europe blames Russia and Russia blames Europe but could the release have come from somewhere else?

The story behind Ru 106 that is given little attention is the fact that it is quite an aggressive isotope that is used mainly in the manufacture of medical isotopes. Its nature is to become very volatile when heated and exposed to air. Then Ru 106 becomes both oxidized which deposits on surfaces and also is lofted into the air in a pure gaseous version. The deposited oxidized version then over time becomes gaseous (which might explain the weeks that the Ru 106 was being sampled in the air.

The main areas of interest to most people is where did it come from? What is a likely source?

After some research I was drawn to the Hungarian nuclear Ruthenium 106 experiments which have run since 2002 (and possibly before) that were…

1,500 Children likely to develop heart problems on a yearly basis- Effects of the Fukushima nuclear disaster – banned by Face Book?

Op Ed Arlight2011part2

Posted to nuclear-news.net

15th April 2012

In an attempt to work out the possible figures of children that will be born annually in Japan with birth defects, I have used the figures below to make an estimation of the likely impact. Based on figures from Chernobyl from Yablakov (2010) of 8, 300, 000 against a similar area in Fukushima Prefecture and the NW Myiagi prefecture (ACRO France) with a population living in contaminated areas of under 2, 500, 000. The figures seem to point to 1,500 children a year are likely to be born in future years with birth defects.

There is obviously some dispute as to the figures and areas of contamination. Also, the contamination in the mountains is likely to hit cities like Koriyama that are downhill of this unknown and untested for contamination. there are also some small issues with the population statistics though they seem about right to me.

#Sellafield workers vote to strike

inde567h7x

Workers at the Sellafield nuclear site have voted to go on strike in a dispute over pay.Unions representing staff at the British Nuclear Fuels plant will meet to discuss whether to set strike dates.

Members of the GMB and Amicus overwhelmingly backed industrial action over a long running grievance relating to pay differentials.

The workers claimed they were promised that a gap of £2,000 between industrial workers and staff would be closed by next April.

Unions have accused the company of reneging on the agreement.

A new report on Sellafield highlights the likely nuclear damage to Ireland. Exclusive to nuclear-news.net

Introduction by Shaun McGee (aka arclight2011)

2 February 2018

The Irish Sellafield nuclear accident fallout projection report has some issues, in my opinion.
In December 2016 the Irish Environmental Protection Agency (EPA) published in Irish Media Sources a report on radioactive fallout from a “worse case” scenario.
At the time, I was in contact with the Irish EPA concerning new evidence that shows a larger health effect from radiation sources and I was trying to challenge the pro nuclear bias that underestimated the health and environmental problems using mechanisms from the EURATOM nuclear treaty in Europe. I have to say that the Irish EPA were forthcoming in their many responses to my inquiries but eventually we reached a stale mate as the EPA claimed that the specific Isotopes relevant to the Euratom Treaty are not to be found in Ireland with the exception of Iodine 131 which they claimed was unlikely to be a health problem. They said that other fission (from a nuclear reactor) isotopes were not found on the island of Ireland.
The 2016 report from the Irish EPA (link) shows, what I think, is a minimal dispersion of radioactive fallout with little impact to health or the environment. However, there are other reports of fallout plumes from the Sellafield site that show much worse contamination than the 2016 EPA report posits and I requested Prof Chris Busby (who had been involved with Irish activists and government groups concerning Sellafield) to do a report (Full report below) on the problems that seemed to be highlighted with the Irish EPA report.
Prof Chris Busby first consulted the online NOAA Hy-Split atmospheric projection software with the same date as the EPA report and got a completely different scenario showing most of Ireland being covered with meandering waves of highly radioactive particles and gases. He then consulted 2 other reports, one of which the Irish Government commissioned that was completed by 2014 using the European gold standard software fallout projection model that showed a large plume covering large sways of Ireland (reaching the south west coast).
It would seem that the 2016 report completely runs counter to the 2014 and earlier report as well as the Hy-Split projection whilst using the same date as the 2016 Irish report.
So the issue of the types of accident that the Irish EPA thought to be worse case scenario. A direct hit by a Meteorite was seen to be plausible but if a meteorite hit sellafield then much of the nuclear site would be lofted high into the atmosphere and more evenly spread around the globe. This would fudge the numbers for plumes that are moving nearer the ground.
No where in the report was the more likely and and more dangerous scenario of terrorists attacking the spent fuel pools causing low altitude fallout over many weeks that would cause a larger pollution incident that would effect local countries to the UK border such as Ireland, Norway etc.In fact such concerns have been reported in main stream media sources as well as government/private think tanks.

Thanks to Prof Chris Busby for taking the time off his busy schedule to compile a response to the Irish EPA report on Sellafields projected damage to Ireland.

Please feel free to leave a comment belowif you agree or disagree with any of the points raised, a discussion about this issue needs to be had.

Conclusion to report

The EPA 2016 report is unsafe and cannot be relied upon by the public, the media or administrators. The anonymous authors have shown extraordinary bias in every aspect of the report. They made elementary mistakes in their source term listing of isotopes, by including those which had short half-lives and will clearly not have been present in any significant concentration. They omitted a whole series of nuclides which are present in the tanks and the fuel pools. They choose a source term which is demonstrably too low based on available data, they choose a worst-case accident which involves only one HAST tank and only Caesium-137. They omit mentioning the spent fuel pools which are a highly likely site of a major coolant loss and subsequent fire or explosion. Their air modelling results are extremely unusual with implausibly narrow plumes, whilst a NOAA HYSPLIT model for the same day shows a completely different dispersion covering most of highly populated Ireland. Their surface contamination levels are 200 times lower than a previous computer model by Dr Taylor, which they must have had access to, and they fail to calculate the increased levels of cancer in the exposed population. This has been rectified here.

Historic releases from Sellafield to the Irish Sea have caused measurable increases in cancer and leukemia in coastal populations of Ireland. There is no doubt that the existence of Sellafield represents a potential catastrophic danger to the Irish Republic. A serious accident there could destroy the country and also most of Britain. As the Chernobyl accident effects showed, and the Fukushima accident effects will reveal (and in the case of Thyroid cancer have revealed) the ICRP risk model is unsafe for explaining or predicting health effects from such contamination. The Authors of the EPA 2016 report should be sanctioned in some way for producing such a travesty of the real picture, especially since they will have had access to the earlier study and modelling by Peter Taylor and the details of the COSYMA model employed by him.

The health impact on Ireland of a severe accident at Sellafield.

A criticism of the report “Potential radiological impact on Ireland of postulated severe accidents at Sellafield” Anon. (Radiological Protection Institute of Ireland: September 2016) with a re-assessment of the range of health outcomes.

Christopher Busby PhD

There are things we know that we know. There are known unknowns. That is to say there are things that we now know we don’t know. But there are also unknown unknowns. There are things we do not know we don’t know.

Donald Rumsfeld

Murphy’s Law is an adage or epigram that is typically stated as:

Anything that can go wrong will go wrong.

[https://en.wikipedia.org/wiki/Murphy%27s_law]

Introduction

The nuclear complex at Sellafield in Cumbria, UK, has always represented a real danger to the Republic of Ireland. There has been and remains a chronic danger to the people of the East Coast of Ireland. First, radioactivity released from Sellafield under licence to the Irish Sea, particularly in the 1970s did not, as had been hoped, dilute and disperse in the sea, but instead became attached to sediment particles along the coasts and inlets of Ireland (e.g. Carlingford Lough, Drogheda) and the particles represented a cause of cancer and illnesses in coastal populations and those exposed through eating fish and shellfish. A court case (Herr and Ors. Vs BNFL) was supported by the Irish State and my organisation was funded by the Irish State for 3 years from 1998 to examine the contamination and health issue. Green Audit examined the cancer rates in small areas in North and mid Wales, and also in Ireland by distance from the contaminated coasts. Results were published in Busby 2006 and showed that there had been a significant 30% increase in cancer and leukemia in coastal populations of the Irish Sea [1]. The second issue of continuing interest is the danger of a serious accident at Sellafield at a time when the wind direction is from the East and airborne material passes across Ireland. This issue became more urgent and of interest to the Irish public after the Fukushima Daiichi reactor explosions and melt-downs in Japan in 2011. However, the potential outcome of such an accident had been part of a report by Peter Taylor [2] written in 1999 for McGuill and Company, the solicitors representing the Herr and Ors vs. BNFL case which was abandoned by the Irish State for reasons which remain unclear.

In September 2016, a report was produced by the EPA Office of Radiological Protection entitled Potential radiological impact on Ireland of postulated severe accidents at Sellafield. [3]. This anonymous report has serious shortcomings and errors which will be addressed here. A more realistic assessment of the potential impact of a serious accident at Sellafield on the Republic of Ireland will be presented here using the radiological risk models both of the International Commission on Radiological Protection (ICRP, [4]) and also the Model of the European Committee on Radiation Risk (ECRR [5]).

 

2. The baseline assumptions of maximum release.

2.1 The EPA worst case.

The EPA report discussed some possible accidents involving releases of radionuclides. It examined some potential sources of radionuclides but not others. It chose a number of possible scenarios, but excluded others. In general terms (and referring to Murphy’s Law, appropriately in this case of Ireland) it could not assess accidents which are totally unforeseen. Therefore, also in general, we should consider a worst case-scenario in which most of the radioactivity inventory of the Sellafield site becomes airborne at a time when the weather patterns were most unfavourable for Ireland.

For example, in Busby 2007 [1] the Windscale reactor fire was examined in some detail. At the time of the fire, which continued for some days, the main releases were initially offshore towards Ireland. This is contrary to the discourse promoted by the British Radiological Protection Board in 1974. It is, however confirmed by Air Ministry historical data. But the point is that at the time a cold front laying North East to South West was moving from Ireland towards England across the Irish Sea. This meant the releases from the fire and heavy radioactive rain fell along the front. This rain fell on the Isle of Man, and historical mortality data show a large increase in the death rate after this event. There have also been reports of significant birth effects (Downs Syndrome cluster) in County Louth reported by the Irish GP Patricia Sheehan, who died in an automobile accident shortly after beginning to follow this up.

In order to estimate the effects of a worst case, initially there must be a choice of the source term, that is, the quantity and radionuclide identity of the material released to the atmosphere.

The EPA report decided that this could be modelled as the contents of one of the 21 High Active Storage Tanks (HAST). The true content of one of these is unknown, probably also to the operators BNFL. The estimate for the contents was taken from a report by Turvey and Hone [6]. This is shown in Table 1 below where I note a number of concerns. In Table 2 I provide examples of some hazardous radionuclides not listed in the EPA source term table. In Table 3 I copy the source terms used by the British 1976 Royal Commission (the Flowers Report) [7]. Note that all these estimates are for a single or multiple HAST tanks on the tank farm and exclude explosions of the spent fuel ponds which could dry up and suffer prompt criticality. This could result from a domino scenario (see below).

2.2 Concerns about the source term table of the EPA 2016 report

Table 1 gives the source terms employed by the EPA report. It lists 13 isotopes. The table is an astonishing example of bad science, produced either through bias or ignorance. Since the table is apparently taken from another report by Turvey and Hone 2000, we can perhaps blame them for the original mistakes. I have included a column showing the half-lives of their isotopes. The main concerns are as follows:
It is perfectly clear than all but four of the thirteen will have physically decayed away by 2016. For example, a half life of Zr-95 of 65 days, at 1980 would by now have had 36 x 365 days to decay. This is 202 half-lives. There would be virtually none left of the listed quantity.
A significant number of seriously hazardous radionuclides which must be in the tanks are not listed. In particular we have Plutonium-239, Plutonium- 238, Plutonium-241, Uranium and other actinide alpha emitters including Neptunium-237, Radium-226, Carbon-14 and Tritium.
The overall total activity tabulated the EPA report is about 4 times less than the quantity in a HAST tank given in the report of the UK Royal Commission 1976 (Flowers) and the 1977 Windscale Enquiry which totalled 1.8 x 1018 Becquerels of Caesium-137 plus 1.4 x 1018 Bq of Strontium-90 plus 1.1 x 1018 Bq of Ruthenium-106 [8].
Why did the EPA report reduce the quantities assumed by the earlier reports? Why did it omit the dangerous actinides Uranium, Plutonium and Neptunium with the exception of Americium-241? Why did it omit a whole range of other radionuclides like Tritium and Carbon-14?

2.8 E+18
Ru-106
1.1 E+18

2.3 The more accurate source terms for HAST tanks

Taylor 1999 [2] based his calculations on only Cs-137 and assumed a source term of 1 x 1018 Bq. Therefore, his results (which I will review below) should be adjusted by a factor of 1.8 on the basis of the Table 3 results, but particularly also modified upwards by the presence of the Sr-90/Y-90 and the actinides, the Plutonium, Uranium, Radium and Americium, which, though they are present in smaller quantities each carry a weighting of 20 due to their alpha biological effectiveness. Thus the quantity of 2.72 E+15 listed by EPA in Table 1 has the effect (in Sieverts) of 5.44 E+16 due to its alpha emission.

2.4 The spent fuel pools

In addition to HAST tank scenarios, there has been reported the existence [ 9: http://www.theecologist.org/News/news_analysis/2611216/leaked_sellafield_photos_reveal_massive_radioactive_release_threat.html%5D in a very dangerous state, a series of concrete spent fuel pools containing hundreds of tons of spent fuel. Loss of integrity of these tanks (drying up) would result in meltdown and prompt criticality with explosive distribution and burning of the spent fuel elements.

The approximate activity inventory of a spent fuel assembly for a Boiling Water Reactor is available from Alvarez 2014 [10] and the EIA for a Pressurized Water reactor fuel assembly from the Swedish Forsmark High Level Waste repository documents [11]. Therefore these are not exactly the same as the assemblies in the Sellafield pools. However, they will not be very different. The radioactive elements and their activity is given in Table 5 [Ref 5,6] .

Comparisons with releases from Chernobyl and Fukushima

Since all these numbers are meaningless without comparisons, Table 6 gives comparisons in terms of Cs-137, which has become a yardstick for releases, discharges and ground contamination in the last 50 years with three contamination events, Chernobyl, Fukushima and the 1950-1980 atmospheric nuclear tests. These are useful comparisons since in the cases of Chernobyl and the nuclear tests, we have evidence for the effects on human health, an issue which is discussed later.

I Visited the Chernobyl Exclusion Zone with an Infrared Camera

Jan 30, 2018

Vladimir Migutin

A few years ago, I visited the Chernobyl Exclusion Zone with an infrared camera. We always hear praises of the might of Mother Nature, how it renders useless mans’ creations and bears life above the ruins. Well, it’s something that is always felt, but never on such a huge scale. This place IS the place for these contrasts.

It’s pretty hard to describe the overall atmosphere I experienced during this trip. Despite the events of 1986, the ruins, and the rust, I didn’t have grim feelings while traveling there. On the contrary, it felt like I was in a “kind of” paradise on a different planet.

Thirty years after the fallout, while men still stay away, the forests, the animals, the plants, everything is thriving, revived by nature.

These photos were shot during a 2-day trip in Chernobyl’s exclusion zone with a full spectrum camera and a 590nm infrared filter from Kolari Vision.

Note from Arclight2011 – It might be worth balancing the issue of a “thriving” ecology etc with these 4 quotes and links;

1/   Chernobyl London meeting (27 April 2013) Speech by Tamara Krasitskava from Zemlyaki

Tamara Krasitskava is a chairperson of Zemlyaki, Ukraine NGO in Kiev to represent those who had to collectively evacuate from Pripyat
* Speech was done by Russian, and interpreted into English.
* Chernobyl Day London Public Meeting was organized by “JAN UK” on Sat 27 April 2013.

“….On Sunday the 27 April 2013 in a little room somewhere off Grays Inn road London, a meeting took place. In this meeting was Ms Tamara Krasitskava of the Ukrainian NGO “Zemlyaki”.

In this meeting she quoted that only 40 percent of the evacuees that moved to Kiev after the disaster are alive today! And lets leave the statistics out of it for a moment and we find out of 44,000 evacuated to Kiev only 19,000 are left alive. None made it much passed 40 years old

“…..3.2 million with health effects and this includes 1 million children…”

T .Kraisitskava

“….I was told to not talk of the results from Belarus as the UK public were not allowed to know the results we were finding!….”

A.Cameron (Belarus health worker from UK)…..”

2/   Fukushima Consequences of Radiation on Wildlife

“….The birds

The feathers of birds take radioactive dust released into the atmosphere continuously by the wind. They therefore suffer permanent external irradiation.

We can see this dust by placing a contaminated bird on a radio-sensitive paper for a month. Here is an example with a bird picked in Iitate in December 2011.

Autoradiography also allows to highlight that the birds also undergo internal contamination…..”

3/   Genetic radiation risks: a neglected topic in the low dose debate.

“…..Taken together with other evidence from sex-ratio (discussed below) these studies indicate that hereditary effects exist in the children of exposed mothers…..”

4/   Life after Fukushima and Chernobyl nuclear disasters with Prof. T. Mousseau

“….Chernobyl, new mice study
Last week Tim said he produced a study showing heightened prevalence of cataracts in the eyes of mice.
and that this was corroborated with an earlier study on birds…..”

Why should you care about ‘specks’ of plutonium? Hanford health challenge

Figure 4

Translocation of inhaled ultrafine particles. Time-activity curve over liver and bladder expressed as percent of initial lung radioactivity. Insert, Whole body gamma camera image of 1 representative volunteer recorded at 60 minutes. The radioactivity over the organs is expressed as counts per minute (CPM) per pixel within each region of interest (ROI). The values recorded over the stomach were not included because this radioactivity may also come partly from swallowing of particles deposited in the mouth. Reproduced with permission from Nemmar et al, “Passage of inhaled particles into the blood circulation in humans”, Circulation 2002;105(4):411-41.

 

Hanford Challenge

Why should you care about ‘specks’ of plutonium?

Even Hanford’s internal reports challenge DOE’s assumption that specks stay in the body for one year. According to one report, high-fired oxide plutonium that PFP handled stays in the body for 10,000 days (i.e. over 27 years).

Why does 10,000 days matter?

Well, the longer the ‘speck’ stays in the human body, the more time it has to cause harm. If a worker was exposed to the high-fired plutonium oxides, the doses to these workers could be 27 times higher than DOE has assumed. (i.e. not good).

So, we must ask: Has DOE measured these particles from PFP and determined whether they are high-fired oxides? Or are they simply assuming? If assuming, what justifies this assumption?

Report excerpt: “retention half-lives for the transport from the lung to the blood have been adjusted from 500 days to 10,000 days [ 27.4 years], representing the highly insoluble (i.e., very slow dissolution rate) of the super class Y material. The precise nature of super class Y material is not known, although it appears to have been associated with processes involving high-fired plutonium oxides … Super class Y is not routinely used as a default program design form.”

These fibres are often described as being in the “interstitial” where they may lie between or within the cells making up the alveolar walls. Bio-persistent solid materials, certainly those particles containing mutagenic substances or asbestos fibres or silica, which remain for years in the lungs, increase the risk of developing cancer.
