Northern Europe: detecting radiation and where it comes from
|
Radiation detections in northern Europe: what we do and don’t know https://thebulletin.org/2020/08/radiation-detections-in-northern-europe-what-we-do-and-dont-know/# By Cheryl Rofer, August 21, 2020 Alarming events may not be what they initially seem. When an enormous explosion created a mushroom cloud over Beirut on August 4, some people immediately jumped to the wrong conclusion, spreading rumors on social media that a nuclear bomb had gone off. It hadn’t.
Eventually it became clear that the explosion was caused by chemicals stored improperly in warehouses at Beirut’s port. But weapons experts knew from the start that the powerful explosion was not nuclear, because it did not produce a blinding flash of light, or a blast of heat intense enough to set a city on fire. In the hours that followed the explosion, the Comprehensive Test Ban Treaty Organization (CTBTO), which operates a network of monitoring stations around the world, did not detect a telltale spike in atmospheric radiation. That last clue is how experts are able to narrow down the location of nuclear events, from the smallest accidents to major disasters like Chernobyl, and to make educated guesses about what happened. A release of nuclear material spreads its signature on the wind. But that signature is often incomplete or garbled. Nuclear experts are still puzzling over a mysterious event that happened in June, when several monitoring stations in northern Europe detected extremely small quantities of radionuclides in the atmosphere. That event was not a nuclear weapons test, because the CTBTO stations did not detect any seismic activity. So what was it? Experts have scrutinized the radiation signature and narrowed down the possibilities. The finger points to Russia. Radiation alerts. Radioisotope monitoring stations cover most of the globe. The CTBTO runs the biggest network. National radiation safety agencies—for example, in Finland and Sweden—operate other stations. Universities also operate monitoring stations, often in cooperation with the CTBTO or national agencies. Independent monitoring organizations, like the volunteer-driven Safecast, also report radiation measurements. In early June, Norwegian monitoring stations and a CTBTO station detected iodine 131 in far northern Norway. On June 16 and 17, Finland’s Radiation and Nuclear Safety Authority (STUK) detected cobalt 60, ruthenium 103, cesium 134, and cesium 137 in Helsinki. On June 22 and 23, a CTBTO station in Sweden detected ruthenium 103, cesium 134, and cesium 137. Radiation is easy to detect at low levels. The iodine 131 readings were around 1 microbecquerel per cubic meter of air. (A microbecquerel is one atomic disintegration per second in one million cubic meters of air.) But our knowledge of the Chernobyl explosion began with measuring small amounts of radionuclides, so any detection raises an alert. Interpreting the detections. The types of radionuclides detected also provide information. The radionuclides detected in June, except cobalt 60, are produced by nuclear fission. The half-lives of iodine 131 and ruthenium 103 are 8 days and 39 days, respectively, so they must be from recent fission events. These are common fission products from a nuclear reactor. A wider suite of radionuclides would help to pin down what kind of reactor. The iodine 131 detection is ambiguous, though. It is produced by fission, but it is also used fairly commonly to treat hyperthyroidism, in pet cats as well as people. It is easily sent into the air. So it may come from sewage plants or other sources. The fact that it showed up without the other fission products means that its source may be something other than a nuclear accident. Cobalt 60 is not a fission product, but rather an activation product of steel that has been in or very close to a nuclear reactor. It doesn’t usually show up with fission products. It could mean that something was broken in the reactor that released the fission products, or it could be that the Finnish reading was in error. Narrowing down the location. Airborne radionuclides by themselves cannot tell us how or precisely where they were released. The CTBTO tweeted a map indicating the region in northern Europe where the June release may have occurred. This map was probably constructed by tracing the winds during the period just before the radionuclides were detected. A couple of Russian nuclear power plants are located in the area identified, which also covers the location where the United States believes a Russian experimental reactor exploded last summer while it was being raised from the seabed. Last month’s release was probably a minor incident, like a breach in a filter at a nuclear power plant. But Russia has said that there were no incidents at its nuclear power plants. The presence of cobalt 60 and the location have led some to suggest that the release may have been from a new attempt to raise that experimental reactor. It’s not possible, with the limited additional data available so far, to do more than guess the origin of the June radionuclides. The source of a similarly ambiguous release of ruthenium 106 in 2017 took two years to identify. In that case, the release of a single fission product suggested a processing facility, and the wind patterns suggested the Mayak facility in Russia. A detailed study of the stable ruthenium isotopes collected with the ruthenium 106 confirmed those early provisional conclusions. Pinning down the source. Last year’s deadly accident seems to have occurred when a reactor for an experimental nuclear-powered cruise missile was being lifted from the seabed. Again, radionuclide readings from monitoring stations some distance from the source gave early warning to the rest of the world. The amounts and numbers of radionuclides were larger than in the recent release, and reporting on the accident, as people were brought to hospitals, provided more information, including radioisotope detection closer to the site, along with satellite photos and, later, photos of the damaged barge. The radioisotopes indicated that a fission source was involved, although early reports from Russia described an “isotopic source,” a phrase usually reserved for single-isotope heat sources, which would be unsuitable for propulsion. In all three of these cases over the past three years, the radionuclides initially detected by air sampling were ambiguous. Additional information was needed to pin down a source. The best information would come from the country responsible for the release – in all three cases, Russia, which is a signatory to the Convention on Early Notification of a Nuclear Accident. Somebody knows what happened in these cases. We need to hear from them. |

UK relations with China at a low point; bad news for nuclear power projects
|
UK nuclear power: The next Huawei? DW, 21 Aug, 20Once a key part of the UK’s energy plans, nuclear power faces rising costs, cheaper renewables and domestic opposition. It also finds itself at the center of a row between London and Beijing that could prove fatal.
London’s relations with China — hailed as entering a “golden era” only four years ago — have deteriorated badly over Hong Kong, hitting a nadir when the UK finally bowed to US pressure to ditch Huawei’s involvement in its new-generation internet (5G) rollout. In late 2019, the US published a list of companies linked to the Chinese military, and after Huawei came the China General Nuclear Power Group (CGN). The state-owned Chinese firm has invested 3.8 billion pounds (€4.1 billion, $4.3 billion) in Britain to date, mainly in the Hinkley Point nuclear plant under construction in Somerset, southwest England, and the Sizewell plant in eastern England. It is also seeking UK regulatory approval to build its own nuclear reactor at Bradwell in Essex, east of London. China warned the UK it would face “consequences if it chooses to be a hostile partner” after London announced its Huawei’s decision. Liu Xiaoming, the Chinese ambassador to the UK, reportedly said China could cut its backing for UK nuclear plants altogether. Years of Chinese involvement in UK nuclear industryCGN’s involvement in the UK nuclear industry began in 2016 when a deal was signed with French state-owned utility Electricite de France (EdF) to collaborate on three reactors totaling 8.7 gigawatts (GW) of power generation, starting with Hinkley Point. The agreement spoke of CGN’s “progressive entry” into the UK’s “resurgent” nuclear ambitions. The UK currently has 15 operational nuclear reactors at seven locations. At its height in 1997, 26% of the country’s power was generated from nuclear, but this has slipped since to 19%. In the Sizewell and Hinkley projects, CGN is providing cash, holding 66% stakes, but with Bradwell it wants to build the reactor itself, using its own technology, and it wants to operate it. Observers say Bradwell is the prize CGN is really seeking: the first Chinese-built nuclear plant outside China. In May, EdF outlined its plans to start work on Sizewell by the end of next year. The project would create 25,000 jobs, it said. But EdF’s continued involvement could be thrown into doubt if no other investor came forward to replace CGN. This is especially troubling given the project is also expected to result in cost overrun. Hinkley Point now costs about 3 billion pounds more than the 20 billion pounds originally planned. Sizewell is also slated to cost 20 billion pounds. “Several projects were planned but only Hinkley Point will likely go ahead,” Jonathan Marshall, Energy and Climate Intelligence Unit (ECIU), told DW. “Bradwell would be a Chinese project, but is now unlikely for political reasons.” Bradwell looks surplus to requirements for the reasons the National Infrastructure Assessment (NIC), a government advisory body, outlined in its most recent long-term assessment: “Given the balance of cost and risk, a renewables-based system looks a safer bet at present than constructing multiple new nuclear power plants,” it read. Financing of nuclear plans unclear“Sizewell is not dependent on CGN investment,” a spokesman from the the Department for Business, Energy and Industrial Strategy (BEIS) said. But not many agree. “Equity funding for nuclear power stations is very difficult for private actors,” Rob Gross, director of the UK Energy Research Centre, told DW. The government’s offer in 2018 to Hitachi to take a third of the equity at the Wylfa nuclear project wasn’t enough to keep the company interested, for example. As Paul Dorfman of University College London’s energy institute and founder of the Nuclear Consulting Group told environmental news platform electrictyinfo.org, it was hard to see who else might invest in Sizewell if the Chinese pull out. “The market won’t touch nuclear with a barge pole. You only see nuclear being built in command-and-control economies, like China and Russia, and a few outliers,” he said. One option would be for the government to take either a majority or minority stake in Sizewell. Another option is a Regulated Asset Base (RAB) model, where consumers are charged a fixed price to cover infrastructure costs. But this would hike energy prices in the long term and make it politically hard to justify. …….https://www.dw.com/en/uk-nuclear-power-the-next-huawei/a-54631808 |

Wow! Only the bare 313 years before the Dounreay nuclear power site could be used for anything else!
uses in 313 years’ time, according to a new report. Dounreay, near Thurso,was the UK site for the development of fast reactor research from 1955 to
1994. The facility on the north Caithness coast is in the process of being
closed down, demolished and cleaned up. However, the Nuclear
Decommissioning Authority said it would be 2333 before the 148-acre site is
safe for reuse. The date forms part of the authority’s newly-published
draft strategy. Waste is to be removed from the Shaft by 2029, according to
the NDA report.
https://www.bbc.co.uk/news/uk-scotland-highlands-islands-53848766
Independent 20th Aug 2020, In 313 years’ time, 378 years after it first opened in 1955, and 339
years after it ceased operations in 1994, the 178-acre nuclear power
facility site at Dounreay will be safe for other uses, a new report has
stated. Though the site on the north coast of Scotland was only home to
functioning nuclear reactors for 39 years, the clean-up will take roughly
ten times as long, with efforts already underway to clean up hazardous
radioactive material. Part of the demolition process has involved the use
of a remote controlled robot nicknamed the “Reactosaurus”, a 75-tonne
device with radiation-proof cameras, and robotic arms which are able to
reach 12 metres into the reactors where they can operate an array of
size-reduction and handling tools, including diamond wire and disks and
hydraulic shears. One of the areas targeted for waste removal is a highly
contaminated area called the Shaft. In 1977, a catastrophic leak allowed
seawater to flood a 65-metre-deep shaft which was packed full of
radioactive waste as well as more than 2kg or sodium and potassium.
Bikini Atoll – food grown there is radioactive – but, it’s “technically habitable”!
Technically Habitable The background radiation of the island has been found to be at normal levels, and even lower than that of some major US cities. While you could walk around on the island and suffer no real ill effects, living there is an entirely different story because of the aforementioned soil and subsequent food contamination.
Ironically for the islanders of Bikini Atoll, the word ‘bikini’ likely comes from ‘pikinni’ which, in the Marshallese language means ‘coconut place
The Radioactive Coconuts of Bikini Atoll, Beginning in 1946, a series of Atomic bombs were tested on and around the Marshall islands, of which Bikini Atoll is one, as both a means of testing and refining the incredibly destructive power demonstrated at Hiroshima and Nagasaki just a year earlier, as well as making a clear statement of US atomic superiority over the Russians. Medium 21 Aug 20, Danny Kane
For those that don’t know, Bikini Atoll was the US’ test site during the 1940s and 1950s for 23 separate Nuclear bombs.
Beginning in 1946, a series of Atomic bombs were tested on and around the Marshall islands, of which Bikini Atoll is one, as both a means of testing and refining the incredibly destructive power demonstrated at Hiroshima and Nagasaki just a year earlier, as well as making a clear statement of US atomic superiority over the Soviet Union.
The Micronesian inhabitants of Bikini Atoll were approached in 1946 by the US government and asked to re-locate while the tests were being carried out. They would be transported to Rongerik Atoll, which is about 6 times smaller than Bikini Atoll — it also has insufficient food and water supplies and was uninhabited at the time………..
The islanders on Rongerik Atoll were starving, the land their being far less fertile than their native Bikini. They were then moved to Kili Island. It was little improvement for the islanders. Relying on fishing for a large part of their diet, they found Kili, which has no lagoons and rough seas most of the year particularly difficult to survive on.
But on March 1st, 1954, the fate of Bikini Atoll was about to take a destructive turn. Ironically, the bomb that was detonated was one of the few not detonated on the Atoll, instead it was detonated on an artificial island 900m from Namu island. This was the infamous Castle Bravo hydrogen bomb. It exploded that day with the force of 15mt , far more than the 6mt that was expected. It was 750 times more powerful that the Fat Man bomb that levelled Nagasaki. It denoted with 2.5 times the expected yield and remains the largest nuclear bomb ever detonated by the US, equivalent to 15 million tonnes of TNT.
Appropriate precautions hadn’t been taken for such a large detonation, and so nuclear fallout rained down on Bikini Atoll, Rongelap Atoll and Rongerik Atoll. 20,000 people were affected by the Castle Bravo detonation and 15 islands and atolls were contaminated. People showed signs of acute radiation sickness, and, on Rongelap, 2 cm of nuclear ash blanketed the entire island. Children, unaware of the fallouts affects, began playing with the falling ash like snow.
Returning Home
Another 19 atomic bombs would be detonated on and around Bikini Atoll, the last one Juniper on July 22nd, 1954, almost 12 years to the day since the Baker detonation. Now, the fight to return to Bikini Atoll really began. Struggling to survive on Kili Island, the islanders were eager to return home.
In spite of all we’d put it through Bikini Atoll had recovered from its years of abuse at the hands of the US. Having been bounced between various islands and atolls since the testing began, Kili had become their permeant home since 1948, but the islands desperately wanted to return home. It wouldn’t be until 1968 until they got the chance. President Lyndon B Johnson promised that the islanders could return, but an investigation by the Atomic Energy Commission found that the radiation levels in the coconut crab, an essential food source for the islanders, were far above normal and acceptable limits. As such, the islanders were forced to remain on Kili island.
Three families did move back in 1972, followed by others in 1987 despite later advice. Issues continued to plague the islanders though, with a boy who’d been born on Bikini Atoll dying from cancer caused by the radiation. In 1982, those that had returned would be evacuated for a second time when it was found that the top 15 inches of soil contained high concentrations of Caesium 137, which would then make its way into the various plants and fruits the islanders ate — and yes, even the coconuts were affected. This resulted in a high number of stillbirths, miscarriages and genetic abnormalities in the children born from those affected by the atomic tests conducted in and around Bikini Atoll. What’s more men were four times as likely to develop lung cancer on the island, women 60 times more likely develop cervical cancer
Over $150 million has been paid to the Bikini islanders as compensation and to reconstruct homes, facilities and institutions for the islanders, many of whom now live on Kili Island. The call to return to Bikini Atoll is still strong though and many point to the fact that the island is still technically habitable.
Technically Habitable
The background radiation of the island has been found to be at normal levels, and even lower than that of some major US cities. While you could walk around on the island and suffer no real ill effects, living there is an entirely different story because of the aforementioned soil and subsequent food contamination.
One proposed solution, and the one favoured by the islanders themselves, is to scrap the topsoil. The top 15 inches of Caesium 137 contaminated soil would be removed and replaced with potassium rich soil. The plants, preferring the potassium over the caesium, would quickly switch to that. While Caesium 137 would still be present in the earth, it would be absent from the food.
There are unfortunately a number of issues with this. Removing the topsoil would have a devasting effect on the ecology of the island and scientists have argued that it would effectively turn Bikini Atoll into a wasteland. This is to say nothing of the expense and the fact that the scraping of the topsoil would likely have to be repeated on occasion to ensure that Caesium 137 didn’t return to the food supply.
Right now, the islanders live on a majority imported food supply and it’s likely that they could continue to do this on Bikini Atoll. It is hardly a return to normal life on the home island though and if the islanders are forced into the same food import practices they’ve had since the 40s, many argue why return to the island at all. Many islanders seem willing to take the risk of destroying the island if it means that they can return their a potentially grow food once more like their ancestors of old.
And so, it remains to this day. The Bikini islanders have never returned home, instead being forced into limbo. Most live on Kili Island today and there are as many as 2,400 Bikini islanders, with fewer than 40 of them having been alive to witness the fires of nuclear fission all those years ago. A great many of them have never even visited their home island, which in recent years has become a tourist attraction. A great many diving tours are offered, especially of the sunken USS Arkansas and the USS Saratoga aircraft carrier, two of the many ships sunk in the testing, as well as the colossal crater left by Castle Bravo…………..

Take the money away from nuclear weapons – spend it on Covid-19 relief
Nuclear weapons must go, https://www.goskagit.com/opinion/letters_to_the_editor/letter-nuclear-weapons-must-go/article_668b33b7-76f9-5a31-9c0c-7c85e222aae3.html, By Kathleen Lorence-Flanagan
On the 75th anniversaries of the Hiroshima and Nagasaki nuclear bombings, there were two days of videotaped testimony by hibakusha (survivors), scientists, artists, students, downwinders, mayors, Marshall Islanders, etc. Moving, informative, and inspiring testimony.
The question that kept arising was why do nuclear weapons still exist? It was said that as weapons of global annihilation, “we need to get rid of them before they get rid of us.”
Total global spending on nuclear weapons in 2019 was $73 billion, $35 billion of that by the U.S. alone (CNN).
Could that money not be better spent for COVID economic relief, education, health care, jobs, etc.?
More spending, deregulation of nuclear waste and resumption of nuclear testing are proposed by the current administration.
A positive note: the UN Treaty on the Prohibition of Nuclear Weapons has recently been signed by three more countries, bringing the total to 43.
A total of 50 are needed, at which point nuclear weapons will fall into the same category as biological and chemical weapons. Hopefully seven more nations will step up to the plate.
The Prospects of Nuclear Disarmament in the New Nuclear Architecture,
The Prospects of Nuclear Disarmament in the New Nuclear Architecture, Modern Diplomacy August 21, 2020, By Hamzah Taoqeer
The debate for arms control and nuclear disarmament has been unfortunately for long has been played as self-serving and hollow pledges by the major NWS which have failed to deliver upon them. The withdrawal from the INF would lead to further lowering of the nuclear threshold as the US would actively develop and deploy tactical nuclear weapons in regions of interest including Asia Pacific and Eastern Europe. The new nuclear architecture developed by the actions of major powers further weaken and deteriorate the efficacy of institutional norms. The efficacy and credibility of new initiatives such as CEND among other remains questionable as the P5 have failed to deliver measurable progress upon the existing arms control and disarmament initiatives.
The emerging nuclear architecture blur the legitimacy of the arms control initiatives and further encourage NNWS to pursue for alternative measures including nuclear weapons program to secure their interests. Thus, resulting in proliferation of nuclear weapons which threaten world peace and security. The major powers should for once initiate a robust implementation upon their aforementioned commitments in good faith rather than devising frameworks for achieving their limited interests……………. https://moderndiplomacy.eu/2020/08/21/the-prospects-of-nuclear-disarmament-in-the-new-nuclear-architecture/

Debate rages on for nuclear waste facility proposed near Carlsbad, more hearings scheduled
Adrian Hedden, Carlsbad Current-Argus, 20 Aug 20, A project to build a temporary storage facility for high-level nuclear waste in southeast New Mexico will continue to be debated as the federal Nuclear Regulatory Commission scheduled four more public hearings to solicit public feedback on the proposal.Holtec International’s proposed consolidated interim storage facility (CISF) would temporarily hold spent nuclear fuel rods at the surface in an area near the Eddy-Lea county line…….. opponents continued to question the safety of the project and its plan to transport spent nuclear fuel from generators across the county and the legality of opening a temporary storage facility when the U.S. lacks a permanent repository for high-level nuclear waste…… The hearings were planned to be held online on Aug. 20 from 4 to 7 p.m., Aug. 25 from noon to 3 p.m., Aug. 26 from 4 to 7 p.m. and Sept. 2 from 9 a.m. to noon. Previously, the NRC held public meetings on the EIS on June 23 and July 9. Written comments were to be accepted until Sept. 22 via email to Holtec-CISFEIS@nrc.gov, via mail to the Office of Administration, Mail Stop: TWFN-7-A60M, ATTN: Program Management, Announcements and Editing Staff, U.S. Nuclear Regulatory Commission, Washington, DC or online to the federal government’s rulemaking page at regulations.gov using docket ID NRC-2018-0052………… Project debated by New Mexico officials, nuclear industry leadersNew Mexico Gov. Michelle Lujan Grisham and state officials voiced continued disapproval of the project, with Lujan Grisham writing a letter to President Donald Trump to voice her opposition last month. Lujan Grisham cited concerns the project could imperil the environment in New Mexico and threaten to disrupt local agriculture and extraction industries in the southeast region of the state…….. https://www.currentargus.com/story/news/local/2020/08/20/debate-rages-nuclear-waste-facility-proposed-near-carlsbad/5604978002/ |

Report: Israel ‘deeply concerned’ by Saudi Arabia, China alleged nuclear cooperation,
|
Report: Israel ‘deeply concerned’ by Saudi Arabia, China alleged nuclear cooperation, MEMO, Middle East Monitor, August 21, 2020 Israel’s Walla news website revealed that Tel Aviv has informed the United States that it was “gravely” concerned by alleged nuclear cooperation between Saudi Arabia and China.The website said senior Israeli intelligence officials had called their American counterparts to express their “grave concern” about the cooperation between Riyadh and Beijing.
According to the site, “unnamed” Israeli officials said there was a secret factory of primitive materials used in uranium enrichment in Saudi Arabia near the capital, Riyadh, explaining that the Wall Street Journal and the New York Times were the first to report on it, including satellite images of the factory. The officials pointed out that the office of Prime Minister Benjamin Netanyahu deals with the file as “very sensitive” politically since Israel considers Saudi Arabia an important ally in the face of Iran. The officials added that the Israeli intelligence services, the ministries of foreign affairs, intelligence and defence, and the Atomic Energy Commission are following the developments of the Saudi nuclear program………. According to Israeli officials, Saudi Arabia has cooperated with China, because the Chinese did not ask for guarantees that the programme would be purely civilian, which is what the United States always demands. https://www.middleeastmonitor.com/20200821-report-israel-deeply-concerned-by-saudi-arabia-china-alleged-nuclear-cooperation/ |
