UK plants turn down energy out put because of cracks developing
Nuclear reactor heat turned down to stop boilers cracking Two nuclear plants shut amid safety fears may be restarted at just 75pc usual power output to prevent more cracks developing, EDF says Telegraph, By Emily Gosden, Energy Editor 17 Oct 14, Power output at two UK nuclear plants will be curbed for up to two years in order to reduce the heat in their boilers and prevent cracks developing, EDF has announced.
The two twin-reactor plants at Heysham 1 and Hartlepool have been shut down since August amid safety fears following the discovery of cracks in one boiler structure at Heysham.
The ageing reactors are likely to be restarted in coming months at just 75pc-80pc of their usual output in order to prevent high temperatures causing further cracks, EDF said on Friday.
The move will further worsen the risk of power shortages this winter and next.
The temporary closure of the plants, which produce enough power to meet about 4pc of peak winter demand, has already forced National Grid to invoke emergency measures to bolster power supplies this winter, by paying mothballed power stations to fire up.
EDF warned in September that the reactors – initially expected to be shut for two months – would only be restarted gradually between the end of October and late December, once safety checks on each reactor’s eight boilers were finished.
On Friday it further revised the likely dates of the restarts. The restart of the reactor with cracks has been pushed back a month, from the end of November to the end of December. Two other reactors have been pushed back from the end of October to November 9, and the fourth reactor has been brought forward from November 30 to November 22………
The cracks at Heysham 1 are in a “boiler spine”. The Office for Nuclear Regulation said that the spine “supports the weight of an entire boiler and its failure could lead to water entering the reactor vessel”.
“The potential worst consequences of water entering the reactor vessel is an over-pressurisation of the reactor which could result in lifting of the reactor pressure relief valves. If this was to occur co-incidentally with fuel damage then there could be a direct path to the environment and a release of radiation,” it said……..
As well as firing up mothballed power plants, National Grid is also using emergency plans to pay factories to switch off on winter weekdays to ease demand to help ensure households’ lights are kept on. http://www.telegraph.co.uk/finance/newsbysector/energy/11169625/Nuclear-reactor-heat-turned-down-to-stop-boilers-cracking.html
Bangladesh’s dangerous nuclear power program
Is a nuclear disaster looming in Bangladesh? http://www.thedailystar.net/is-a-nuclear-disaster-looming-in-bangladesh-46005 Abdul Matin 16 Oct 18, The writer is a former chief engineer of Bangladesh Atomic Energy Commission.
The Bangladesh Atomic Energy Regulatory (Amendment) Bill, 2014 was passed by the parliament on September 14. Surprisingly, instead of bringing the qualifications and experience in conformity with the IAEA guidelines, the amendment further relaxed the qualifications of the top brass of BAERA to “adequate qualification and experience about nuclear energy management.” “Adequate qualification and experience” is a vague term subject to interpretations. In technical terminology, it carries little significance. Moreover, management of nuclear energy does not necessarily imply nuclear safety. The door has thus been opened, perhaps deliberately, to any Tom and Harry to occupy the top positions of BAERA. It shows that the authorities are least concerned about the safety of the proposed nuclear plant at Rooppur.
The real motive for making the amendment is a mystery. It is probable that the changes were made because of unavailability of sufficiently qualified and trained engineers. In that case, our priority should have been to train necessary manpower first before embarking on an ambitious nuclear power programme. Furthermore, the concerned authorities are solely responsible for creating this crisis. They, perhaps due to negligence or incompetence, did not initiate any serious programme of recruitment and training of nuclear engineers during the last six years in spite of our strong recommendations at a round table organised by The Daily Star and ABUETA (DS, May 10, 2009) and attended by the adviser on power and energy and the state minister of science and technology. Did we not have enough time to train at least fifty nuclear engineers with MS degrees by now if we had acted promptly at that time?
The recent amendment could partly relax the experience only in selected cases but certainly not the requirements of qualifications or training. How can one ensure nuclear safety without a solid background (at least at MS level) in nuclear engineering and nuclear reactor safety? It is inconceivable and unacceptable in the nuclear industry. By relaxing the qualifications and experience of the top officials of the BAERA, the authorities have acted most irresponsibly and put the country at the risk of a likely ‘man-made’ nuclear disaster.
Russia protects nuclear weapons stockpiles from cyber sabotage
Cyber security units to protect Russia’s nuclear weapons stockpiles RT.com October 17, 2014 The IT systems of all Russian nuclear weapons stockpiles will be protected by a new team of anti-hackers, the Defense Ministry said after a year-long “hunting season” for programmers.
Special units of the Russian Strategic Missile Forces (SMF), responsible for the country’s nuclear weapons, will reduce the vulnerability, should it be found, in their brand-new information systems, according to the Defense Ministry’s spokesman……..http://rt.com/news/196720-russia-missile-forces-cybersecurity/
Radiation samples falsified to make Hunters Point look clean
Contractor Submitted False Radiation Data at Hunters Point, NBC Bay Area In an internal report uncovered by the Investigative Unit, Tetra Tech says it provided the Navy false soil samples while working on the radiological cleanup of the Hunters Point shipyard By Vicky Nguyen, Liz Wagner and Felipe Escamilla Monday, Oct 13, 2014
A Navy contractor tasked with cleaning radioactive soil at the Hunters Point Naval Shipyard in San Francisco admitted in an internal report obtained exclusively by the NBC Bay Area Investigative Unit that it mishandled soil samples and submitted false data.
Tetra Tech, a multinational engineering, construction and environmental corporation details in an April 2014 report how it was caught submitting false soil samples to the Navy in an apparent effort to declare the soil free of radiological contamination when it may not have been. The Pasadena-based company is a $2.7 billion per year business that has won more than $300 million worth of contracts for cleanup work at Hunters Point………
“If the Navy had not caught this,” Bowers said, “there would be very, very high levels of contaminated soil, radioactive soil in the ground, where the plans are in place to build homes for the general public to live in, with yards for children to play in.”
Bowers is one of four radiation specialists who blew the whistle on Tetra Tech’s practices and are now suing the company for retaliation, claiming they were fired after questioning the company’s actions. Bowers first spoke with the Investigative Unit earlier this year saying the cleanup of Hunters Point had been compromised and that Tetra Tech cut corners on safety to save money……..http://www.nbcbayarea.com/investigations/Contractor-Submitted-False-Radiation-Data-at-Hunters-Point-279025911.html
Canada’s public to get iodine pills in wide area around nuclear reactors
Nuclear plants must give iodine pills to nearby residents, regulator says Radiation protection pills will be pre-distributed to people and businesses located near nuclear plants, according to a new regulation announced by the Canadian Nuclear Safety Commission on Friday. The Star, By: John Spears Business reporter, Oct 10 2014
Residents and businesses near nuclear plants must be given radiation protection pills as a precautionary measure, says Canada’s nuclear regulator.
The pills must be pre-distributed, before any accident occurs, in co-operation with government authorities.
The Canadian Nuclear Safety Commission announced the new measure Friday, as it published a new regulation. The pills, which contain potassium iodide, block the thyroid gland from absorbing radiation.
The regulation requires nuclear operators to pre-distribute the pills to “all residences, businesses and institutions” within the primary area where the plume from a radiation release would likely spread.
The radius of the area may vary from location to location but “is typically sized in the range of eight to 16 kilometres,” according to the regulation. A 10-kilometre radius from the Pickering nuclear plant would extend from the eastern part of Scarborough to Whitby.
In a larger zone — typically 50 to 80 kilometres — nuclear plant operators must make sure that there is a stock of pills “ready for prompt distribution” and “located so that it can be efficiently obtained by, or distributed to, members of the public when required,” the regulation says.
An 80-kilometre zone would embrace all of Greater Toronto………The regulation also requires nuclear plant operators to deliver emergency preparedness information “in hard copy annually to every residence, business and institution” within the pill pre-distribution area. http://www.thestar.com/business/2014/10/10/nuclear_plants_must_give_iodine_pills_to_nearby_residents_regulator_says.html
Whose finger is now on the nuclear button, in North Korea?
Kim Jong-un Disappearance Leads to Nuclear Weapon Concerns Liberty Voice, by Rebecca Savastio on October 10, 2014. Kim Jong-un’s continuing disappearance has led to speculation about whose finger is on the North Korean nuclear weapon arsenal. The Supreme Leader of the Democratic People’s Republic of Korea has not been seen in over a month. Why should the world care? Does it matter to anyone outside of North Korea if he is vacationing, ill, deposed or dead? The fact that North Korea is a nuclear power, though without the capability to launch nuclear intercontinental ballistic missiles at the United States, makes the tiny communist nation’s stability of interest for everyone…….
……..The true state of politics within North Korea is an impenetrable mystery. It is disconcerting that the world knows so little about a country it fears so much. Given its nuclear capabilities, any change of government needs to be smooth and stable. Many feel that the only scenario worse than a communist dictator who hates America is a rogue element with nothing to lose. Whether orchestrated by Kim or accomplished without his authority, the moves made by the North Korean officials seem to be a small step in the right direction. The world is waiting to see what happens, because Kim Jong-un’s continuing disappearance had led to speculation about whose finger is on the North Korean nuclear arsenal. http://guardianlv.com/2014/10/kim-jong-un-disappearance-leads-to-nuclear-weapon-concerns/#gCOhfjJo3gRiifyJ.99
On anniversary of Windscale nuclear accident, UK plans another untested reactor
57 years ago today in 1957 :The Windscale Fire, Radiation Free Lakeland, 10 oct 14 ” ……..10th Oct marks 57 years since the worst nuclear accident in the UK. The bravery of those who fought the 1957 blaze was without question and they are remembered with our gratitude for preventing the far greater catastrophe of a full on Lake Counties nuclear sacrifice zone.
Official estimates point to a possibility of 240 additional cancer cases as a result of the Windscale fire. Studies reveal that the impacts of nuclear accident and routine emissions may be far wider reaching than the public is led to believe. One such study in 1995 by Dr John Bound, a former paediatrician at the Victoria Hospital, Blackpool; Brian Francis, of the Centre for Applied Statistics, Lancaster; and Dr Peter Harvey, pathologist at the Royal Lancaster Infirmary found that the Windscale fire
was followed by a surge in cases of Down’s syndrome. Their studies were poo poohed to protect the vested interests of the nuclear establishment.
This pattern has been repeated time and time again. History is now repeating itself with the plan for untried and untested new build near Sellafield.
The ruthless push towards new nuclear build on the beautiful coastline of West Cumbria mirrors the rush to build Windscale in order to produce plutonium for the atomic bomb. While “safety features” like the last minute addition of filters on the Windscale chimney helped mitigate the impact of the inevitable fire, the dangers from nuclear are inherent and accumulative. Nothing it seems is being learnt from history. The same old uranium burning technology is being proposed now for new build. The reactors being proposed are AP1000, a scaled up version of the commercially unattractive AP600. The AP1000 boasts higher efficiency, in other words it burns the uranium harder and longer producing much hotter wastes, reactors under construction now in America and China have cooling towers 600 – 800 ft. high. The other “alternative” is direct cooling with huge sea installations.
Sellafield is dangerous enough and a big enough terrorist target without putting untried, untested nuclear reactors next to it with the possibility of enormous cooling towers the size of New York sky scapers or huge sea installations.
Please remember the Windscale fire on the 10th. Remember the voluntary bravery of the Windscale workers and the involuntary bravery of all those unacknowledged babies, children, men and women who have died, or suffered health consequences as a result of the Windscale accident. The still highly radioactive chimney which stands 350ft tall has also claimed the life of steeplejack Neil Cannon who died after falling from the ongoing ‘decommissioning’. The death toll will continue without end if new build goes ahead. Surely the time has come for Cumbrians to say enough is enough and to join the resistance to new and more dangerous nuclear build.There is a petition here:

South Korea’s nuclear unsafety – 684 Accidents and Failures over 37 Years
Korean Nuclear Power Plants Exposed to 1,843 Hacks over Five Years– Business Korea 10 OCTOBER 2014The number of hacking attempts against nuclear power plants in Korea was found to have reached 1,843 during the last five years. Experts are calling for special cybersecurity measures for nuclear power stations under the circumstances…..684 Accidents and Failures over 37 Years
With the situation as it is, the general public’s concerns over aging nuclear power plants as well as hacking attempts are on the rise. The total number of nuclear power generation accidents and breakdowns in Korea has reached 684 since the commercial operation of Gori 1 back in 1978. Out of those, 130 have happened in the oldest facility.
“The government is just repeating that nuclear power generation is a safe way of power supply,” Democratic United Party lawmaker Moon Byung-ho explained, continuing, “However, it would be well advised to reexamine its safety, security, sustainability, and economic advantages by taking this as an opportunity and shutting down the oldest nuclear power stations for a paradigm shift.” http://www.businesskorea.co.kr/article/6718/security-unawareness-korean-nuclear-power-plants-exposed-1843-hacks-over-five-years#sthash.iaBiCo9G.dpuf

Volcanoes a rare risk to nuclear reactors, but consequences would be devastating
Difficulties remain in protecting nuclear plants from volcanic eruptions October 05, 2014 THE ASAHI SHIMBUN by Takeshi Nakashima and Chikako Kawahara The deadly eruption of Mount Ontakesan in central Japan has rekindled concerns about whether Japan’s nuclear power plants, such as the Sendai plant in Kagoshima Prefecture, have adequate safeguards for dealing with such a disaster………
Active volcanoes are located near the Sendai plant, with Mount Sakurajima about 50 kilometers away and Mount Kirishima about 60 km away.
In the past, huge volcanic eruptions have led to the formation of large calderas and pyroclastic flows in the area.
Major eruptions occur in Japan about once every 10,000 years. However, nuclear plants have to implement measures depending on the risk even if the frequency of an event is low.
Nuclear plants are not designed to withstand pyroclastic flows at high temperatures. For that reason, if such flows should reach a facility, the consequences could be disastrous.
Kyushu Electric insists that the possibility of an eruption while the Sendai plant is operating is sufficiently low. The utility also says it would be possible to capture signs of a major eruption and remove nuclear fuel beforehand.
The Nuclear Regulation Authority has supported Kyushu Electric’s position.
The removal of the nuclear fuel from the reactors is expected to take several years.
However, the Mount Ontakesan eruption once again demonstrated the limits to accurately predicting volcanic eruptions.
Concerns about the safety measures at the Sendai plant were raised at a Sept. 30 session of a special committee of the Kagoshima prefectural assembly. Some members raised doubts about whether early signs of an eruption could be detected. Others criticized Kyushu Electric’s position………http://ajw.asahi.com/article/behind_news/social_affairs/AJ201410050034
UK’s Atomic Weapons Establishment found unsafe, by regulator
UK nuclear bomb factories rapped by watchdogs over radioactive waste
Atomic Weapons Establishment issued with non-compliance notice by Environment Agency over handling of hazardous waste Rob Edwards heguardian.com, Thursday 2 October 2014 Britain’s nuclear bomb factories have been reprimanded by two government watchdogs for breaking safety rules on radioactive waste.
AWE, the private consortium that operates Trident nuclear weapons facilities at Aldermaston and Burghfield in Berkshire for the Ministry of Defence, has come under fire from the Environment Agency (EA) and theOffice for Nuclear Regulation (ONR) for failures in managing its hazardous waste.
The EA has issued AWE with a non-compliance notice because key posts meant to ensure the safe handling of wastes have been vacant for months. These include waste officers, radioactive specialists and the head of environment…….
“ONR is continuing to investigate AWE’s failure to meet the requirements of the licence instrument, in accordance with our normal processes,” said an ONR spokesman. “ONR will consider enforcement action in accordance with our enforcement policy when all investigations are completed.”…….
“Since 2010 safety and environmental regulators have increasingly had to take action at the Atomic Weapons Establishment, and it is time to start asking whether AWE are fit to run this complex and hazardous site if they are unable to improve standards.” http://www.theguardian.com/environment/2014/oct/02/uk-nuclear-bomb-factories-rapped-by-watchdogs-over-radioactive-waste
Shambles of Japan’s plans for evacuation after the next nuclear accident
Not nearly enough buses for mass exodus after nuclear accident THE ASAHI SHIMBUN by Masanobu Higashiyama and Hiroki Koike.27 Sept 14 The gargantuan task of moving residents in a nuclear crisis will fall on chartered buses, according to the local governments’ evacuation plans.
The problem is there may not be nearly enough vehicles to move huge numbers of people to safety.
Some prefectures already realize they would be lucky to assemble just half the number of buses for the job.
There is also opposition from bus companies, which say they will not subject their drivers to hazardous radiation risks.
In a 10-kilometer radius of Kyushu Electric Power Co.’s Sendai nuclear power plant in Kagoshima Prefecture, which has passed safety checks for a restart, surveys show that local governments can charter only one-fourth of buses that would be needed to evacuate residents.
Although the prefecture plans to sign an agreement with the prefectural association of bus companies to preferentially charter vehicles, a local bus drivers’ union said it will oppose the plan unless safety measures for drivers are mapped out.
According to evacuation plans submitted by Satsuma-Sendai, the city hosting the nuclear plant, and surrounding municipalities within a 30-km radius of the plant, people who need nursing care and others without family cars will have to evacuate by bus……..
In addition to the lack of buses, the void of safety measures to prevent bus drivers from being exposed to radiation during an evacuation casts a shadow on plans by local governments to use chartered buses.
Central government guidelines stipulate that ordinary people such as bus drivers must not be exposed to more than 1 millisievert of radiation annually in normal situations. However, there are no measures in place to deal with those who are exposed to higher readings.http://ajw.asahi.com/article/0311disaster/fukushima/AJ201409270012
In addition, rules for distributing potassium iodide tablets to protect against thyroid cancer due to radiation have yet to be devised……..
During an Aug. 29 news conference, Niigata Governor Hirohiko Izumida asked if it is realistic for residents to rely on chartered private buses in a case of a nuclear disaster. The prefecture hosts Tokyo Electric Power Co.’s Kashiwazaki-Kariwa nuclear power plant.
“Is it possible to make drivers from private bus companies work in areas that are highly contaminated with radiation?” Izumida asked.
Officials at Fukushima Prefecture’s Nuclear Power Safety Division said they had not confirmed reports that bus companies refused to send vehicles due to concern for drivers’ safety during evacuation procedures for the Fukushima nuclear disaster.
But some trucks transporting relief goods did refuse to enter areas that were highly contaminated with radiation, according to the officials.
“A private company can face legal charges if its employees are exposed to radiation because of work orders,” said an official of Niigata Prefecture. “Even if we sign an agreement with bus companies, it will not ensure the efficacy of such an evacuation plan.”
USA and Russia co-operate in removing Polish high-enriched uranium
US says cooperates with Russia in removing Polish high-enriched uranium, Thomson Reuters Foundation Source: Reuters – By Fredrik Dahl VIENNA, Sept 22 (Reuters) – The United States said on Monday it had worked with Russia to help remove 50 kg of highly-enriched uranium from Poland as part of a global campaign to reduce the use of nuclear fuel that could also serve as material for bombs.
Washington and Moscow continue to cooperate on a case-by-case basis in areas of mutual nuclear security concern despite a current “substantial strain” in their relations, U.S. Secretary of Energy Ernest Moniz said………
The U.S.-based Arms Control Association, a research and advocacy group, last year said that HEU spent fuel from converted research reactors in Poland would be returned to Russia by the end of 2016.
In mid-2013, the United States and Russia used another IAEA meeting in Vienna to announce that they had helped ship out nearly 16 kg of HEU from Vietnam.
There are about 1,440 tonnes of HEU and 500 tonnes of plutonium stockpiled and in nuclear arms globally, the Nuclear Security Governance Experts Group (NSGEG), which lobbies for action to ensure that such material does not fall into the wrong hands, said last year.
Most of these stockpiles are under military guard but some for civilian uses is less stringently secured.
Analysts say that radical groups could theoretically build a crude but deadly nuclear weapon if they had the money, technical knowledge and materials needed but that merely obtaining sufficient material for an attack poses a formidable challenge.
A fairly simple-to-design bomb would require about 50-60 kg of HEU, the NSGEG said. More sophisticated devices would requires less material.
A message from U.S. President Barack Obama read by Moniz to the IAEA meeting in Vienna said the United States continued to work successfully with Russia to implement the new START treaty, “decreasing our deployed strategic warheads to the lowest levels in nearly 60 years”.
The pact that was agreed in 2010 caps deployed strategic nuclear warheads, those meant to travel long including intercontinental distances, in Russia and the United States at 1,550 each by 2018, down from the previous ceiling of 2,200. http://www.trust.org/item/20140922165343-gvnzt
Major impediments to re-opening New Mexico nuclear waste dump
Energy Dept. faces major hurdles to reopen New Mexico nuclear dump LA Times, By RALPH VARTABEDIAN 18 SEPT 14, The Energy Department has identified 7,000 steps needed to reopen its badly damaged nuclear waste dump in New Mexico, but cannot say how long it will take or how much it will cost.
The agency was expected to release a written recovery plan Thursday, but instead provided a few details about the plan, which awaits formal approval by the department.
Outside experts say that the dump will probably not reopen until well after the start of 2016 and that the cost of the accident will approach $1 billion. Although they didn’t talk about the cost, Energy Department officials reiterated at a briefing in Carlsbad, N.M., on Thursday that there was “strong support” in Congress for putting up the unspecified amount of money required to restart the plant. A Senate aide declined a request by the Los Angeles Times earlier this month for details about the cost negotiations……..
Don Hancock, nuclear waste program director at the Southwest Research Institute, a watchdog group, said the system of isolating the waste by spraying water on the salt is unproven.
Hancock said the Energy Department has repeatedly told state regulators that the dump would not reopen before early 2016, but he said that estimate is highly optimistic because so much remains unknown about the recovery.
Even if the dump reopens by then, the two-year shutdown would have consumed two years’ worth of the annual budget for the operation, amounting to about $400 million, and at least another $300 million of additional appropriations that have been discussed for repairs.
But that is unlikely to cover the full cost of the repairs, Hancock said. In addition, tons of waste are backing up across the nation, forcing laboratories and other cleanup sites to store radioactive material longer, at an unspecified cost…..http://www.latimes.com/nation/la-na-nuclear-waste-dump-20140919-story.html
