The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Unknown – whether there were nuclear missiles on Russian ship that was ravaged by fire

Bellona 27th Feb 2018, A Russian official has admitted there were missiles aboard the
Yekaterinburg nuclear submarine when it was ravaged by fire during repair
work at a shipyard near Murmansk in late 2011, reviving a six year old
mystery about what specific dangers faced the Russian public when the
accident occurred.

And while many Russian media rushed to report the
official’s remarks as conclusive proof that the submarine was armed with
nuclear missiles when it was swept by the blaze, it remains unclear whether
they, in fact, had been topped with their warheads at the time the fire
swept through the sub, injuring 19.

A forgotten nuclear disaster? 1985 Russian submarine accident

In 1985, a Russian Submarine Created an Atomic Disaster. The Radiation Lingers to This Day.  Kyle Mizokami, 27 Feb 18, 

According to Nuclear Risks, the accident scene was heavily contaminated with radioactivity. Gamma ray radiation was not particularly bad; at an exposure rate of five millisieverts per hour, it was the equivalent of getting a chest CT scan every hour. However, the explosion also released 259 petabecquerels of radioactive particles, including twenty-nine gigabecquerels of iodine-131, a known cause of cancer. This bode very badly for the emergency cleanup crews, especially firefighters who needed to get close to the explosion site, and the nearby village of Shkotovo-22. Forty-nine members of the cleanup crew displayed symptoms of radiation sickness, ten of them displaying acute symptoms.

In 1985, a Soviet submarine undergoing a delicate refueling procedure experienced a freak accident that killed ten naval personnel. The fuel involved was not diesel, but nuclear, and the resulting environmental disaster contaminated the area with dangerous, lasting radiation. The incident, which remained secret until after the demise of the USSR itself, was one of many nuclear accidents the Soviet Navy experienced during the Cold War.

The Soviet Union’s nuclear war planners had a difficult time targeting the United States. While the United States virtually encircled the enormous socialist country with nuclear missiles in countries such as Turkey and Japan, the Western Hemisphere offered no refuge for Soviet deployments in-kind.

One solution was the early development of nuclear cruise missile submarines. These submarines, known as the Echo I and Echo II classes, were equipped with six and eight P-5 “Pyatyorka” nuclear land attack cruise missiles, respectively. Nicknamed “Shaddock” by NATO, the P-5 was a subsonic missile with a range of 310 miles and 200- or 350-kiloton nuclear warhead. The P-5 had a circular error probable of 1.86 miles, meaning half of the missiles aimed at a target would land within that distance, while the other half would land farther away.

The missiles were stored in large horizontal silos along the deck of the submarine. In order to launch a P-5 missile, the submarine would surface, deploy and activate a tracking radar, then feed guidance information to the missile while it flew at high altitude. The system was imperfect—the command link was vulnerable to jamming, and the submarine needed to remain on the surface, helpless against patrol aircraft and ships, until the missile reached the target. Eventually the P-5 missiles were withdrawn and the P-5 missile was replaced with the P-6, a similar weapon but one with its own radar seeker for attacking U.S. aircraft carriers.

The introduction of the P-6 gave the Echo II a new lease on life.  ……

On August 10, the submarine was in the process of being refueled. Reportedly, the reactor lid—complete with new nuclear fuel rods—was lifted as part of the process. A beam was placed over the lid to prevent it from being lifted any higher, but incompetent handling apparently resulted in the rods being lifted too high into the air. (One account has a wave generated by a passing motor torpedo boat rocking the submarine in its berth, also raising the rods too high.) This resulted in the starboard reactor achieving critical mass, followed by a chain reaction and explosion.

The explosion blew out the reactor’s twelve-ton lid—and fuel rods—and ruptured the pressure hull. The reactor core was destroyed, and eight officers and two enlisted men standing nearby were killed instantly. A the blast threw debris was thrown into the air, and a plume of fallout 650 meters wide by 3.5 kilometers long traveled downwind on the Dunay Peninsula. More debris and the isotope Cobalt-60 was thrown overboard and onto the nearby docks.

According to Nuclear Risks, the accident scene was heavily contaminated with radioactivity. Gamma ray radiation was not particularly bad; at an exposure rate of five millisieverts per hour, it was the equivalent of getting a chest CT scan every hour. However, the explosion also released 259 petabecquerels of radioactive particles, including twenty-nine gigabecquerels of iodine-131, a known cause of cancer. This bode very badly for the emergency cleanup crews, especially firefighters who needed to get close to the explosion site, and the nearby village of Shkotovo-22. Forty-nine members of the cleanup crew displayed symptoms of radiation sickness, ten of them displaying acute symptoms. …….

 The K-431 incident was one of several involving Soviet submarine reactors. Ten Soviet submarines experienced nuclear accidents, and one other, K-11, also suffered a refueling criticality….http://nationalinterest.org/blog/the-buzz/1985-russian-submarine-created-atomic-disaster-the-radiation-24669

Flamanville EPR: defects affect secondary circuit welds in nuclear reactor

Actus Environnement 23rd Feb 2018, [Machine Translation] The welds of the Flamanville EPR would not meet all the technical requirements. ASN will give its opinion in the second half of 2018. It also
mentions dysfunctions in the organization of the site.

On February 22nd, EDF announced that it had detected defects in the secondary circuit welds
of the EPR reactor under construction in Flamanville (Manche). In question:
the quality of realization of the welds of the circuit which evacuates
steam of the steam generators towards the turbine.

Thirty-eight of the 66 welds in the circuit are affected. Questioned on the subject in the
National Assembly, Pierre-Franck Chevet, president of the Nuclear Safety
Authority (ASN), described the subject as “serious” .

This Friday, the ASN publishes a note in which it indicates to have questioned February 7 EDF
and Framatome about the site of the EPR. The gendarme of the nuclear
indicates that it “informed EDF and Framatome that it will collect the
opinion of the permanent group of experts for GP ESPN nuclear pressure
equipment [about the anomalies of welding]” . But, assures EDF, “[the]
pipes are in compliance with the regulation of nuclear pressure equipment”

France; EDF discovering many more “anomalies ” and “non-conformities” in nuclear reactors

Nuclear Transparency 23rd Feb 2018 [Machine Translation] Review of forgings at Le Creusot: EDF discovered
1,063 anomalies and 233 nonconformities on 23 reactors. Following the  discovery of numerous irregularities at Creusot Forge, now Framatome, EDF continues its review of the parts installed in its reactors.

A first report was published in September 2017 . A second assessment has just been posted. EdF makes a count of compliance discrepancies by distinguishing “non-conformities” that relate to an internal requirement to the
manufacturer of “anomalies” relating to the regulatory or customer’s external requirements.

Some anomalies are similar to falsifications, according to the ASN. There are now 1,063 anomalies and 233 nonconformities out of 23 reactors only. Others are expected.   http://transparence-nucleaire.eu.org/revue-pieces-forgees-creusot-edf-a-decouvert-1-063-anomalies-233-non-conformites-23-reacteurs/

Thursday Blog 24th Feb 2018, EDF has just revised upwards the number of defects affecting its reactors. The latest count of the company reports 1,063 ” anomalies ” (553 more than September 2017) and 233 ” non-conformities ” (103 more) on the equipment of  23 of its operating nuclear reactors. Added to this are 95 anomalies and 16 non-compliances on Flamanville EPR equipment revealed in September 2017.

These results are the result of EDF’s checks on all equipment manufacturing records from the plant. du Creusot (26732) and installed on its reactors. EDF released this second wave of results on Thursday 22 February.

Steam drainage pipes made by EDF and Fromatome (i.e. AREVA) not all safe

ASN 23rd Feb 2018 [Machine Translation] The ASN college questioned EDF and Framatome
(formerly Areva NP) about the deviations in the welding of the main steam
drainage pipes.

The first discrepancies were brought to the attention of
the ASN in early 2017. These pipes are affected by a so-called “rupture
exclusion” approach, which implies a strengthening of design, manufacturing
and service monitoring requirements. This reinforcement must be sufficient
to consider that the rupture of these pipes is extremely improbable.

It allows the operator not to fully study the consequences of a rupture of
these pipes in the safety demonstration of the installation. In order to
achieve the expected high quality of production, strengthened requirements
including mechanical properties were defined by the operator (EDF) and the
manufacturer (Framatome).

However, these reinforced requirements have not
been specified to the subcontractor in charge of producing the welds. The
controls carried out during manufacturing in the factory have shown that
they are not all compliant for certain welds. As a result of an ASN
inspection, this observation has been extended to other welds of these
pipelines made at the Flamanville site.

France’s nuclear regulator censures EDF over Flamanville project welding problems

French nuclear watchdog raps EDF over Flamanville failings,  Regulator says EDF must improve pre-startup testing, Orders EDF to send it report on weldings problems (Adds ASN comment on welding problems), By Geert De Clercq, PARIS, Feb 23 (Reuters) – French nuclear regulator ASN said it has told EDF to improve the running of the construction of the Flamanville nuclear reactor, which is years behind schedule and billions over budget.

The ASN has repeatedly said a schedule to load nuclear fuel at the EPR reactor in Flamanville, which is the same type as EDF is building in Britain’s Hinkley Point, by year-end is tight.

ASN said EDF must improve the follow-up of pre-startup test as well as the treatment of any flaws, and to improve the information flow to the regulator.

“EDF has promised to put in place an action plan to remedy these dysfunctions,” ASN said in a statement on Friday.

The ASN also said it had questioned EDF and Framatome, the company formerly called Areva, about flaws in the welding of the Flamanville reactor’s steam pipes.

………Any further delay to Flamanville would be another blow to the image of the EPR reactor. Three others have been under construction for years in Finland and China and are all over budget and schedule.

It could also force EDF to increase its cost estimate for the reactor, which it last updated to 10.5 billion euros in September 2015, from an original estimate of 3 billion euros. https://www.reuters.com/article/edf-flamanville/update-1-french-nuclear-watchdog-raps-edf-over-flamanville-failings-idUSL8N1QD2G2

Chinese and USA officials scuffled over the “nuclear football”

Nuclear football’ scuffle broke out during Donald Trump’s visit to China , ABC News 20 Feb 18 

A scuffle broke out between Chinese and US officials over the “nuclear football” — the briefcase containing the US nuclear launch codes — during a visit to Beijing by US President Donald Trump last year, according to media reports.

Key points:

  • Report says Chinese official tackled to ground
  • Secret Service confirms scuffle but not tackle
  • Chinese not believed to have taken possession of briefcase

US news website Axios said multiple sources confirmed an incident in which Chinese officials tried to block a military aide with the briefcase from following Mr Trump into the Great Hall of the People, despite the aide being required to stay close to the President at all times.

The report said when Mr Trump’s chief of staff Mike Kelly attempted to intervene, a Chinese official tried to grab him before a US Secret Service agent tackled the Chinese official to the ground.

The Secret Service did not initially deny the incident took place, but in a tweet said reports that a host nation official was “tackled” to the ground were “false”.

The federal law enforcement agency later confirmed an incident had taken place……..

The “nuclear football” is a leather briefcase that contains the codes needed to launch a nuclear strike while away from fixed command centres.

It is carried by a rotating group of military officers near the President whenever he is travelling. http://www.abc.net.au/news/2018-02-20/scuffle-broke-out-over-nuclear-football-during-trumps-china-trip/9463976

Earthquake in New Hampshire raises new concerns about safety of Seabrook Station Nuclear Power Plant

Quak e rattles anti-nuclear activists in N.H.http://www.bostonherald.com/news/local_coverage/2018/02/quake_rattles_anti_nuclear_activists_in_nh, Dan Atkinson Friday, February 16, 2018 

Government officials said an earthquake centered less than 10 miles from Seabrook Station Nuclear Power Plant didn’t seem to have caused any damage yesterday, but anti-nuclear activists are worried the tremors could have increased instability in already-cracking containment walls.

The 9:28 a.m. quake, which shook the ground in northern Massachusetts and southern New Hampshire but only hit 2.7 on the Richter scale, didn’t trigger any emergency procedures at Seabrook Station, Nuclear Regulatory Commission spokesman Neil Sheehan said. The station is just down the road from the earthquake’s epicenter in East Kingston.

Sheehan said workers walked through the plant yesterday in search of any signs of damage, but stressed Seabrook Station is built to withstand much stronger earthquakes.

But activists said many of the plant’s walls — including in the spent fuel pool and the reactor dome — are already weakened. And though they’re several feet thick, they’ve been damaged by water mixing with compounds in the walls’ concrete and cement, creating a gel that expands and cracks the walls.

Paul Gunter, a director at activist group Beyond Nuclear and a former member of the Clamshell Alliance that led large protests against Seabrook coming online in the 1970s, said activists have long been concerned by the power plant’s proximity to an earthquake zone. He said yesterday’s tremor was a “wake-up call.”

“Even these small earthquakes are a wake-up call to look at the broader issues of vulnerability at the plant and the inherent danger of the operation,” Gunter said. “These are legitimate reasons to question the continued operation of Seabrook Station.”

Natalie Hildt Treat, executive director of C-10, a Newburyport-based group that monitors emissions at the plant, agreed.

“You would think a measurable earthquake would put further stress on that,” she said. “Little cracks can lead to bigger cracks … it’s definitely a safety concern.”

But Seabrook Town Manager William M. Manzi III said he wasn’t concerned that the quake caused any structural damage, saying, “We’re confident that the plant will be able to withstand any seismic event.”

Plant owner NextEra Energy didn’t respond to multiple requests for comment. The company is seeking to extend its license to operate from 2030 to 2050, and Sheehan said the NRC is currently reviewing NextEra’s plans to address deterioration before it considers an extension.

“The real issue here is longer-term,” Sheehan said. “In terms of the earthquake today, we don’t believe it poses a safety issue.”

A gigantic nuclear garbage pool for France: that is EDF’s dangerous plan

EDF plans to build a giant nuclear garbage pool in Belleville-sur-Loire instead of stopping producing unmanageable waste!http://www.sortirdunucleaire.org/EDF-projette-de-construire-une-piscine-poubelle February 13, 2018

On February 13, 2018, the Reporterre site revealed the new EDF project. In view of the prolongation of the operation of nuclear reactors and to unclog the four basins of the La Hague plant where used fuel is stored, the electrical firm wants to build a giant new “pool of deactivation” near the Belleville plant -sur-Loire (Cher). We strongly condemn this imposed, dangerous and expensive project. Rather than create a new trash, EDF must turn off the tap and dry up the production of unmanageable radioactive waste!

In France, spent fuel is stored in “deactivation pools” for the time needed to cool them (between 3 and 5 years). If each nuclear power plant has its own pool adjoining the reactor building, the La Hague plant (Manche) hosts 4 pools in which are immersed more than 10,000 tons of spent fuel, representing a hundred reactor cores waiting for a improbable “reprocessing”. Supposedly temporary, storage in these pools has been going on for 40 years. Consequences: the pools are full and the space is running out. Instead of starting a decline in spent fuel stocks by stopping the production of electricity from nuclear power, EDF is stubborn and plans to build an additional pool in Belleville-sur-Loire. But the experience of La Hague shows that the use of these pools goes hand in hand with disproportionate risks.

Vulnerable pools and potentially dramatic accidents The 4 cooling pools at the La Hague plant concentrate the largest volume of radioactivity in Europe. Belleville-sur-Loire could soon compete with this facility. Oversized, the giant basin that EDF plans to build in Belleville-sur-Loire could accommodate up to 8,000 tons of spent fuel, the equivalent of 93 cores of reactors.

This project is all the more worrying because EDF is never very concerned about the protection of the reactor deactivation pools it operates. Will the centralized Belleville pool be protected as recommended by nuclear safety authorities around the world since Fukushima? Nobody can say it. And the risk increases even if EDF chooses not to bunkerize the building that contains the pool, as is the case at the Orano factory in La Hague, where the basins are protected by a vulgar tin roof

… But even with a concrete hull, in the event of an accident, the amount of radioactivity released into the atmosphere would be incommensurate with the releases resulting from an accident in the core of a reactor: to concentrate in the same place such a quantity of radioactive material has intrinsic risks. And what about the dangers of transporting such large quantities of radioactive waste across France?

The Belleville-sur-Loire swimming pool project poses even more safety problems because it is supposed to house the assemblies of MOX – a mixture of uranium and plutonium oxides – a particular fuel that, when it is used, releases much more radioactivity than “normal” uranium assemblages. And since MOX can not be reprocessed or reused, temporary storage in this pool could well become permanent storage.

Finally, in normal operation, these pools are allowed to reject radioactivity. If a new bin of this kind were built, dangerous radioelements like tritium or krypton 85 would inevitably end up in the environment.

An opaque and expensive project EDF led this project with complete opacity. At the time Greenpeace submitted a report that points to the fragility and dangerousness of the 62 cooling pools scattered over the hex, EDF plans to build a 63rd, size XXL. Discussed on the sly, well protected from democratic choices and far from energy issues, the project was kept secret by EDF.

Once again, citizens and residents of the region are faced with a fait accompli. Still, the idea is in the pipes for a long time. Urged by ASN – which invited it in 2013 to “revise its spent fuel management and storage strategy, by proposing new storage methods” – EDF, to comply with the National Plan management of radioactive materials and waste, once again chose the worst option.For EDF and the promoters of the atom, the construction of such an installation is only one way of guaranteeing new outlets for a declining nuclear industry and of claiming to ensure the management of spent fuel for a new period.

The “Sortir du nucléaire” Network strongly denounces this project and, alongside the associations of the region, will resolutely oppose its implementation. In no case this pool is a “solution” to the problem of the accumulation of radioactive waste. In order not to generate new risks and to put the costs of a disproportionate installation on the citizens, the only solution is to dry up the production of this unmanageable waste. Press contacts: Martial CHATEAU: 06 45 30 74 66 Catherine FUMÉ: 06 62 84 13 88

2020 Japan Olympics and the threat of nuclear terrorism

Japan, IAEA agree to cooperate on Tokyo 2020 nuclear counterterrorism, Nikkei Asian Review, 16 Feb 18, VIENNA (Kyodo) — The Japanese government and the International Atomic Energy Agency signed an agreement on Thursday to work together to keep the Tokyo 2020 Olympics and Paralympics safe from the threat of terrorism involving nuclear materials.
 According to the Japanese Foreign Ministry, the agreement includes measures to support IAEA experts’ participation in events relating to the Tokyo games, the exchange of information on nuclear security issues and the loan to Japan of equipment to detect radiation.

Foreign Minister Taro Kono and IAEA Director General Yukiya Amano observed the signing in Vienna before holding a meeting at which Kono said they agreed to flesh out cooperation in thwarting nuclear terrorism.

“We want to thoroughly cooperate with the IAEA to make sure the Olympics are safe,” Kono said at the outset of the meeting……..https://asia.nikkei.com/Politics-Economy/International-Relations/Japan-IAEA-agree-to-cooperate-on-Tokyo-2020-nuclear-counterterrorism

China again delays building Westinghouse-designed AP1000 nuclear reactor, because of safety worries

China nuclear reactor delayed again on ‘safety concerns’ https://www.cnbc.com/2018/02/12/china-nuclear-reactor-delayed-again-on-safety-concerns.html

  • Fuel loading at the world’s first Westinghouse-designed AP1000 nuclear reactor on China’s east coast has been delayed due to “safety concerns” — the latest in a long line of setbacks for the project.
  • Officials with the U.S.-based Westinghouse had expected fuel loading to start last year, and it would have been followed by around six months of performance tests before the reactor could go into full operation in 2018.

Fuel loading at the world’s first Westinghouse-designed AP1000 nuclear reactor on China’s east coast has been delayed due to “safety concerns” — the latest in a long line of setbacks for the project, the China Daily reported on Tuesday.

The third-generation reactor, located in Sanmen in Zhejiang province, was originally expected to make its debut in 2014.

Officials with U.S.-based Westinghouse had expected fuel loading to start last year, and it would have been followed by around six months of performance tests before the reactor could go into full operation in 2018.

 But fuel loading has now been suspended as China tries to ensure the project meets the highest possible safety standards, the China Daily said, citing a spokesman with the China National Nuclear Corporation (CNNC).

Westinghouse was not immediately available for comment when contacted by Reuters on Tuesday.

Westinghouse, owned by Japan’s Toshiba, signed an agreement in 2007 to build four AP1000 reactor units at two sites in China, hoping the projects would serve as a shop window for the firm.

But the company filed for bankruptcy last March, hit by billions of dollars of cost overruns at four nuclear reactors under construction in the United States.

China was originally seen as the lifeline for the global nuclear sector, with the country keen to approve dozens of new reactor projects to ease its dependence on polluting coal-fired electricity.

China is currently targeting total installed nuclear capacity of 58 gigawatts by the end of 2020, up from 35.8 gigawatts by the end of last year. It also said it would aim to have another 30 gigawatts under construction by the end of the decade.

But the pace of planned nuclear construction in the country was scaled back in 2011 in the wake of the Fukushima disaster in Japan.

Delays to the Sanmen and Haiyang AP1000 projects, as well as the French-designed European Pressurised Reactor units at Taishan in Guangdong province, have held back the sector, and no new nuclear project has been approved in China in two years.

China’s nuclear firms are currently building their own homegrown third-generation reactor design known as the Hualong One.

Producing plutonium “pits” – too dangerous for New Mexico

Sante Fe New Mexican 10th Feb 2018, New Mexico’s senators and congressmen are making a bad choice for their
constituents by lobbying to retain the production of nuclear bomb triggers,
or “pits,” at Los Alamos National Laboratory. The production of
plutonium pits is one of the most toxic industrial processes on Earth.

It is hazardous for workers and pollutes our environment for centuries. Los
Alamos has a poor safety record, according to the Department of Energy.
Only Los Alamos, among 24 nuclear sites recently audited by the department,
did “not meet expectations” for criticality risks. This is the risk of
a nuclear chain reaction that can irradiate workers and cause an explosion
or catastrophic toxic fire.  http://www.santafenewmexican.com/opinion/my_view/nuclear-bomb-production-wrong-for-n-m/article_4696f035-fef3-58a9-a258-16ad82d97cae.html

Stable Iodine Must Be Distributed Before Nuclear Accidents Not After Them

 http://www.ianfairlie.org/news/stable-iodine-must-distributed-nuclear-accidents-not/January 29, 2018

Because of the risk of possible terrorist attacks at the 15 UK nuclear reactors and >20 nuclear reactors in nearby countries, and because of the advanced ages of UK nuclear reactors, there is a need for greater preparedness to deal with nuclear accidents and incidents.

For these reasons, in June 2016, the House of Commons Science and Technology Committee set up an Inquiry on Science in Emergencies: chemical, biological, radiological or nuclear incidents.  However neither the Committee’s subsequent poor Report nor the Government’s anodyne response dealt with the real issues in a forthright and open matter. In particular, they discussed neither the problems of evacuations (which I have discussed) nor the scientific evidence which amply supports the pre-distribution of stable iodine as occurs in most other EU countries.

In the event of a nuclear accident or incident, the three main responses are shelter, evacuation, and stable iodine prophylaxis. This article deals solely with iodine prophylaxis.

It is important to note that stable iodine ingestion only protects against thyroid cancer, and not any other cancers which could arise after exposure to the many nuclides which would be released if a serious nuclear accident or incident were to occur.  However it is the only cancer that we can prevent or mitigate if advance preparations are made.

The prior ingestion of stable iodine (often potassium iodide, ie KI) is an effective means of protecting the thyroid gland from thyroid cancer and other thyroid effects, especially among children. But it is necessary to consume stable iodine immediatelyafter a nuclear incident: the best way to provide for this is the advance distribution of stable iodine prior to any accident or incident.

In the UK, the Government has decided not to pre-distribute stable iodine tablets to the public. This is a poor decision. It was probably influenced by the Government’s  strong support, bordering on obsession, for nuclear power. In other words,  political considerations are held to be more important than public safety. Information on the locations of stale iodine supplies, stocks held, and arrangements for their distribution in the event of a nuclear incident or accident is unavailable in the UK.

After the warning of a nuclear accident or incident, it appears that the Government intends to distribute stable iodine to “…schools, hospitals and evacuation reception centres…” and “collection centres” for collection by the public. It is likely that such  distribution would take at least two days or longer, depending on the sizes of the affected areas. During this time, plumes would continue to cross such areas depending on the nature of the accident, wind direction and wind velocity.

At present, the Government assumes that most thyroid doses (from the radioative iodine in the plumes) will occur via the food pathway, mainly from the ingestion of milk and leafy green vegetables. This pathway could take a few days and could give time for stable iodine distribution to take place. However recent scientific evidence indicates that inhalation is much more important than ingestion for radio-iodine doses. This means advance stable iodine distribution is vitally necessary. The Government is ignoring this information, thereby putting the UK public at risk.

Several EU countries have already pre-distributed KI to all families. In addition, KI supplies and dose information are available on line from non-UK sources. It is therefore recommended that

  • Stable iodine tablets, with clear dose instructions and the reasons for their advance distribution, should be distributed to all families within at least 30 km of nuclear facilities in the UK without waiting for an incident or accident to occur.
  • Since radioactive plumes could reach cities with large populations (e.g. >500,000 people) located beyond 30 km, stable iodine pre-distribution should carried out here as well. This is because rapid evacuations from such large cities would be impractical, but their inhabitants should be afforded some protection.
  • For this reason, and to deal with the possibility of radioactive plumes from nuclear reactors on the continent, the Government should pre-distribute stable iodine to all families throughout the UK, as occurs in most other European countries.

A more detailed (9 pages) report can be found here main report on KI.

Questioning France’s National Agency for the Management of Radioactive Waste (Andra)

Le Monde 7th Feb 2018, [Machine Translation] Bure landfill: the impossible scientific proof of
safety. “The World” had access to the thesis of a researcher who studied
the management of uncertainties surrounding the storage of nuclear waste in
the Meuse.

It is an embarrassing document for the promoters of the
Industrial Center of geological storage (Cigeo) aiming to bury, in the clay
subsoil of the village of Bure, in the Meuse, the most dangerous French
nuclear waste.

It describes how the National Agency for the Management of
Radioactive Waste (Andra), unable to formally demonstrate the safety of
this facility for hundreds of thousands of years, dedicates its efforts to
convince the nuclear control authorities of the feasibility of such
storage. At a loss to present some of his results in a biased or incomplete
way. Beyond this public institution, under the tutelage of the ministries
in charge of energy, research and the environment, it is also the chain of
evaluation of nuclear safety in France that is questioned.
