Nuclear withdrawal was thanks to women, says former energy minister, https://www.swissinfo.ch/eng/nuclear-withdrawal-was-thanks-to-women–says-former-energy-minister/46423854 5 Mar 21, Having four women in Switzerland’s seven-person 
government played a key role in the decision to phase out nuclear energy ten years ago, according to Doris Leuthard, who was energy minister at the time of the nuclear disaster in Fukushima on March 11, 2011.
The three other female cabinet ministers at the time were Micheline Calmy-Rey and Simonetta Sommaruga from the left-wing Social Democratic Party and Eveline Widmer-Schlumpf from the centre-right Conservative Democratic Party.Leuthard, from the centre-right Christian Democratic Party, admitted that she didn’t immediately realise the scale of the disaster at Fukushima.
“My first reaction was to say that that’s very far away from us, in Japan, in a country that deals seriously and professionally with events of this kind. I didn’t realise right away that it was a major disaster,” she told Le Temps.
In an interviewExternal link with Swiss newspaper Le Temps on Thursday, Leuthard said she would have had a hard time convincing men on the political right to abandon nuclear power.
“I think women are generally more sensitive to the environment and to the risks to which the population is exposed. When safety is at stake, they are willing to look at new solutions, even if it means paying a little more. They were more quickly convinced that we could opt for a new energy mix,” said Leuthard, who stepped down from the government at the end of 2018.
Only gradually did it become clear how serious the disaster was and that Switzerland had to act. On March 14 the government imposed a moratorium on nuclear projects.
“It was a decision that had to be taken quickly because, at the time, we intended to replace the three oldest [nuclear] plants with a modern, new-generation facility. We had to carry out a new risk analysis and see whether we could maintain the nuclear option in our energy policy. We informed the owners of the Swiss power plants, who had submitted applications to build this new-generation facility. It was a difficult moment, as our decision could cause them significant damage. […] I must admit that I didn’t sleep very well for two nights.”
In the end Switzerland did decide in 2011 to phase out nuclear power, which supplies about a third of the country’s electricity production.
In 2017 Swiss voters endorsed a new energy law that aims to promote renewable energy by banning new nuclear power plants and reducing energy consumption.
In December 2019 the 47-year-old Mühleberg nuclear power plant near Bern was permanently switched off – the first of five Swiss nuclear power reactors to be decommissioned. The event was considered so important that viewers could follow the progress live on Swiss television.

Technical problem shuts down Swiss nuclear power station, SwissInfoCh, 29 Dec 19, The Leibstadt nuclear power station in northern Switzerland has been disconnected from the power grid and shut down because of a technical fault.
Once the cause has been clarified, the plant will be put back into operation as soon as possible, the operator said. It is not clear when that will be. ……
Transducers replaced
Two reactor shutdowns had already occurred at Leibstadt in April and May 2019. Both had the same cause. According to ENSI a malfunctioning transducer led to incorrect values in a channel of the main steam pressure measuring system. These triggered a rapid closure of the turbine inlet valves.
……Saturday’s shutdown comes a week after the 47-year-old Mühleberg nuclear power plant near Bern was permanently switched off. It was the first Swiss nuclear power reactor to be decommissioned. https://www.swissinfo.ch/eng/leibstadt_technical-problem-shuts-down-swiss-nuclear-power-station/45461886

Switzerland to shut down first nuclear reactor le News18/12/2019 BY LE NEWS
On 20 December 2019, Switzerland will shut down the Mühleberg nuclear reactor in the canton of Bern. The plant went into operation in 1972, making it the nation’s second oldest nuclear power station after Beznau, which started its first reactor in 1969.
The Mühleberg power station, which takes its cooling water from the Aare river, was originally scheduled for shutdown in 2012. This date was later extended to 2019. Fissures in the mantle surrounding the reactor and rising operating costs mean the plant is no longer economically viable.
Groups concerned about the safety of the reactor are celebrating. The safety justification for the nation and it neighbours for shutting down this reactor has existed for a long time, according to Philippe de Rougemont, a spokesperson for the group Sortir du nucléaire, a group that organised an unsuccessful referendum in 2016 to precipitate the phaseout of Switzerland’s nuclear power industry.
The Mühleberg reactor, which is the closest Swiss reactor to Lausanne and Geneva, must now be decommissioned. Radioactive material must be cooled, processed and disposed of safely. The organisation Sortir du nucléaire said it will keep a close eye on this process, which it considers a major risk.
Switzerland has five nuclear reactors on four sites. After the 2011 nuclear accident at Fukushima in Japan, the Federal Council, Switzerland’s executive, said it would build no new nuclear reactors and decommission existing nuclear power plants at the end of their safe operational lifespans. It estimated the safe operational lifespan to be about 50 years, which means Beznau I would be taken offline in 2019, Beznau II and Mühleberg in 2022, Gösgen in 2029 and Leibstadt in 2034. However, the government made no commitment to close any nuclear reactor by a specific date. The Federal Council was supported by parliamentary and upper house majorities……. https://lenews.ch/2019/12/18/switzerland-to-shut-down-first-nuclear-reactor/

The world’s oldest nuclear power plant, By Jack Unwin Power Technology, 16 Oct 19, A look at Beznau nuclear power plant in Switzerland, the world’s oldest nuclear power plant currently in operation…….
Construction on the plant began in 1965 and Beznau 1 began producing power on 1 September 1969, with Beznau 2 following in 1972. It has two pressurised water reactors (PWR) built by Westinghouse with a capacity of 365MW each, for a total capacity of 730MW and able to produce 6000 gigawatt-hours (GWh) of energy. The plant is owned and operated by Swiss private company Axpo Holdings.
Accidents will happenDespite its long run producing power, Beznau has been no stranger to accidents at its site. According to the Swiss Federal Nuclear Safety Inspectorate, there were 91 nuclear security incidents between 1995 and 2014.
However 86 of these were at level 0 on the International Nuclear Event Scale (INES), the least severe on its scale. Four were at level 1 and one in 2009 that was level 2, when two workers at the plant were exposed to “inadmissible” levels of radiation .

Court orders Swiss authorities to publish arms export data https://www.swissinfo.ch/eng/war-materiel_court-orders-swiss-authorities-to-publish-arms-export-data/44918258 APRIL 24, 2019 Switzerland’s highest court has ruled that the State Secretariat for Economic Affairs (SECO) must give a Swiss journalist company data on arms exports.
The Federal Court rejected an appeal by SECO which had refused to transfer detailed information to a journalist from the WOZ newspaper on companies that had filed arms exports requests in 2014.
In a decision published on Wednesdayexternal link, the court backed an earlier ruling by the Federal Administrative Court on behalf of the WOZ journalist, who had filed a freedom of information request.
Last March, the Federal Administrative Court had ruled in favour of the journalist, stating that it was public interest to ensure greater transparency and information on arms exports and that the media played an important role in holding the authorities to account in this regard.
SECO had argued that, in accordance with the law on war materiel, only the parliamentary oversight committee should be sent the details on Swiss arms exports. It said that publishing details on arms exports could also displease importing countries.
However, the Federal Court said publishing such information was not a threat for Switzerland’s interests. If there is no business secret involved, SECO must publish the firms’ names.
Hot topic
Rules governing arms exports and calls for greater transparency remain a hot topic in Switzerland. In 2008 the government tightened rules on arms exports; in 2014 it relaxed them on behalf of parliament.
In October 2018 the government abandoned plans to ease Swiss weapons exports following a public outcry.
In December 2018 campaigners started collecting signatures for a people’s initiative to prevent the Swiss government from relaxing rules for exporting arms to conflict-ridden states.

What a Swiss nuclear disaster could do to Europe, Swissinfo.ch , By Susan Misicka, MAY 21, 2019 – If there were to be a serious accident at one of Switzerland’s nuclear reactors, many of the radiation victims would be residents of other countries.
A Swiss-led study has calculated the potential effect of nuclear meltdowns on the health of people living nearby. Its focus is on how meteorology and geography would influence the movement of a radioactive cloud.
For example, this clip [on original] illustrates how the weather conditions on January 19, 2017 would have shaped the aftermath of an accident at the Gösgen reactor between Bern and Zurich.
The study was led by Frédéric-Paul Piguet at Institut Biosphèreexternal link, an interdisciplinary research institute in Geneva. Piguet and his team examined the accident risk at Switzerland’s five nuclear power plants, which fall between Fukushima and Chernobyl in terms of size. This includes 50-year-old Beznau I in northern Switzerland, the oldest nuclear reactor in the world.
The research team used the weather conditions throughout 2017 to calculate the fallout of disasters at the Swiss reactors and concluded that 16-24 million Europeans would be affected by a nuclear meltdown in Switzerland, which itself has a population of 8.5 million. They reckoned that 12,500-31,100 people would die on account of cancer and heart problems caused by the radiation. On top of that, there would be additional health problems, including genetic maladies and sterility.
According to the study, wet weather would nearly double the number of severe radiation-related illnesses. In 2017, there were 36 such “bad weather” days. The study is being presented in detail on Tuesday in Bern………. https://www.swissinfo.ch/eng/worst-case-scenarios_what-a-swiss-nuclear-disaster-could-do-to-europe/44977606

Historic nuclear accident dashed Swiss atomic dreams https://www.swissinfo.ch/eng/radioactive_historic-nuclear-accident-dashed-swiss-atomic-dreams/44696398 JAN 21, 2019
Fifty years ago today, a nuclear meltdown occurred in Switzerland’s first experimental nuclear power station. Built in an underground chamber in Lucens in the western part of the country, it was the site of the worst nuclear accident in Swiss history.
The plant was opened in 1962, with the aim of not only producing energy, but also allowing Switzerland to develop a reactor bearing the “Made in Switzerland” label and enabling experiments with nuclear energy.
But these plans were pushed aside when disaster struck in the plant’s reactor cavity on January 21, 1969. A pressure tube burst which created a power surge leading to the reactor malfunctioning and an explosion. Luckily, a member of staff who was scheduled to be working on the reactor at the time was found safe and sound elsewhere. The plant’s underground design also prevented people and the environment from being harmed.
The accident’s severity registered at 5 out of a possible 7. The concentration of leaked cooling gas that was behind the door of the reactor cavity was lethal. It wasn’t even possible to measure the radioactivity because it was above the maximum level on the measuring instruments.
But the reactor cavern was not completely sealed: the radioactivity spread to the control room 100 metres away. In the machine cavern closest to the reactor, a team involved in shutting down the turbine had been exposed to radiation. A witness report said that since the decontamination showers had been out of order, the workers had to shower in a temporary facility without hot water.
The government ordered an inquiry into the incident and a report was eventually published ten years later. The Swiss Association for Atomic Energy found there had been no major negligence on the part of the plant’s managers. The cause of the incident was corrosion in a pressure tube, brought about by humidity.

Government under pressure to sign nuclear ban treaty, SWISS INFO.CH DEC 12, 2018 Parliament has urged the Swiss government to ratify a United Nations accord banning nuclear arms and to submit it to a political debate for approval.The Senate on Wednesday followed the House of Representatives approving a formal call thereby overruling a government decision earlier in the year not to sign the Treaty on the Prohibition of Nuclear Weapons (TPNW).
Supporters said failure to sign the accord sent a negative message to the international community and undermined Switzerland’s credibility as a champion of humanitarian law………
The TPNW will enter into force when at least 50 countries ratify it. Signatories have obligations not to develop, test, produce, acquire, possess, stockpile, use or threaten to use nuclear weapons. The agreement also prohibits the deployment of nuclear weapons on national territory and assistance to any country involved in prohibited activities.
So far, 67 countries have approved the treaty and another 19 have ratified it. https://www.swissinfo.ch/eng/parliament_government-under-pressure-to-sign-nuclear-ban-treaty/44613098

Swiss nuclear power plant forced to reduce production as warmer waters in river struggle
to cool reactors https://www.thelocal.ch/20180727/swiss-nuclear-power-plant-forced-to-reduce-production-as-warmer-waters-in-river-struggle-to-cool-reactors The Local, news@thelocal.ch @thelocalswitzer 27 July 2018
The Mühleberg Nuclear Power Plant in the canton of Bern has announced it is reducing its output due to the rising temperature in the river Aar, which cools the plant’s reactors.
The plant this week announced it has reduced its energy production by more than 10 per cent because of the record temperatures in Switzerland. The hottest summer since 1864 has seen water temperatures in many water bodies rise above 23 degrees Celsius, threatening aquatic fauna, and now energy supplies.
“We have reduced the reactors’ power to 89 per cent,” Tobias Habegger, a spokesman for the BKW Group, the energy company that manages the plant, told Swiss news portal 20 Minutes.
The Mühleberg Nuclear Power Plant is obliged by law to reduce production once temperatures in the Aar river exceed 20.5 degrees Celsius. This is the second reduction – already on July 5th the power plant was ordered to reduce production as a safety precaution, according to the same report.
The nuclear power station in Mühleberg is the first to have had to curtail production because of the current heatwave. The nearby power plant in Beznau is functioning normally. That plant only has to take similar safety precautions once temperatures in the Aar river exceed 32 Celsius.
The Mühleberg Nuclear Power Plant, which has been active since 1972, will be the first in Switzerland to be disconnected as of December 2019, according to a statement by the BKW Group.

Abnormal bugs found around Swiss nuclear power plants http://www.beyondnuclear.org/home/2018/7/11/abnormal-bugs-found-around-swiss-nuclear-power-plants.html A new study, believed to be the first to investigate health effects on insects near operating nuclear power plants, has found a highly significant twofold increase in morphological malformations on true bugs in the 5 km vicinity of three Swiss nuclear power stations.
The study — Morphological Abnormalities in True Bugs (Heteroptera) near Swiss Nuclear Power Stations — was conducted by Alfred Körblein, a physicist and authority on the health impacts of low-dose radiation, and Cornelia Hesse-Honegger, who has studied and painted insects affected by the Chernobyl nuclear accident. (You can read more about Hesse-Honegger’s work here.) Earlier studies on wildlife around Chernobyl and Fukushima found large and highly statistically significant incidences of radiation-induced mutation rates. Due to its ecological design, however, the Swiss study cannot answer the question whether the effect is caused by radiation from nuclear power plants. However, given the results, the researchers are calling for future studies to confirm their findings. Read the study.

Radioactive jewellery recalled in Switzerland swissinfo, 7 May 18 A Swiss company has sold esoteric “negative-ion” jewellery containing high levels of uranium and thorium. The Federal Office of Public Health has written to people who have bought the jewellery, telling them to send it to the health office.
Health office spokesman Daniel Dauwalder on Monday confirmed media reports that an unnamed company had imported rock powder from China with levels of the two radioactive substances that were harmful for skin cells and the outer skin layer.
The health office said if the bracelets, necklaces and earrings were worn for several hours a day over a year, the skin’s dose threshold of 50 millisieverts could be exceeded. In the long term, the risk of skin cancer would increase, it added.
….The radioactive rock powder was discovered by German customs guards, who informed the Federal Office of Public Health.
Dauwalder said the office had already received many items of jewellery, which would be disposed of accordingly. The jewellery must not end up in the normal rubbish, the office said.https://www.swissinfo.ch/eng/uranium-earrings_radioactive-jewellery-recalled-in-switzerland/44101980

Nucnet 16th March 2018, US-based Westinghouse Electric Company has completed a decommissioning
project at the Barseback nuclear power station in Sweden that included the
underwater segmentation and packaging of the reactor vessel internals.
Westinghouse said it had also carried out upfront engineering studies, and
equipment manufacturing and qualification for the project, which was part
of the first dismantling and decommissioning of a commercial nuclear power
plant in Sweden.
Barseback-2, a 600-MW boiling water reactor unit, began
commercial operation in July 1977 and was permanently shut down in May
2005, with decommissioning work beginning in August 2016. The closure
decision, announced in October 2004, followed what the government described
as failure to reach an agreement with the power industry on the details and
timetable for a voluntary phaseout of Sweden’s nuclear facilities Its
sister unit, Barseback-1, was permanently shut down in November 1999.
Westinghouse said it is now due to begin decommissioning work on
Barseback-1, with an estimated completion date of April 2019.

GDF Watch 2nd Feb 2018, A week on from the Environmental Court’s ruling, and it would seem nobody in Sweden is any the wiser about what happens next. The general view seems to be that this is a hiccup, and everything will eventually continue as planned.
But don’t expect that to happen anytime soon, and at least not until after this autumn’s national elections in Sweden. Anders Lillienau, who chaired the Court’s Hearings, is reported as saying that while they had significant concerns about the safety of the copper canisters, the Court did not otherwise see any barriers to the safety of the repository.
The Court has asked SKB, the organisation responsible for the repository, to provide further information on copper canisters to address their concerns. It is understood that SKB are preparing such information, and reportedly told a community meeting in Östhammar earlier this week that they intend to provide that information later this year.
Anders Lillenau has also made clear the ball is now in the Government’s court: “In the
end, it is still the case that the Government may make the overall assessment whether or not this will be allowed.” A Swedish Government spokesman, Magnus Blücher, explained that this was a complex issue and it was too soon to say what the Government might do, or when.
Back in Östhammar, the local referendum planned for 4 March has been postponed. The referendum was advisory, and any final decision on agreeing to host the repository has to be taken by the local council. A spokesman for Östhammar Municipality says that it is too soon to know when the referendum and council vote will now take place.
Local resident Åsa Lindstrand chairs a resident’s group opposed to the repository. She told the local newspaper that she was pleased but surprised by the Court’s decision, but feels little will change:
“Actually, nobody else in Sweden wants this nuclear fuel repository, so the rest of Sweden would probably be lucky if someone takes it. The municipality is so marinated by SKB that it is not easy to
say ‘no’. For us who live here, it’s more about noise and traffic than about the copper capsules, it’s happening before they get there at all.” Her sense of pyrhhic victory is shared by environmentalist Johan
Swahn, who added, “but only if the government stays passive and the copper canister issues raised by the Court become a matter solely for SKB.” His organisation, MKG, has raised concerns about the long-term
safety of copper canisters over many years.
While delighted that the Court accepted the case presented by leading corrosion scientists, he now wants
the Swedish Government to guarantee an open scientific re-evaluation of the issues relating to copper canister corrosion. http://www.gdfwatch.org.uk/2018/02/02/sweden-update/
