Coolant removed from Dounreay Fast Reactor, WNN 05 August 2016 A ten-year process to remove 68 tonnes of highly-radioactive liquid metal coolant from the primary circuit of the UK’s Dounreay Fast Reactor (DFR) has now been completed, marking a major milestone in its decommissioning.
Dounreay’s experimental fast breeder reactor, housed inside a steel sphere, led British nuclear R&D during the 1950s and 60s. It became the world’s first fast reactor to provide electricity to a national grid in 1962…..Dounreay Site Restoration Limited (DSRL) announced today that some 68 tonnes of the liquid metal coolant – a blend of sodium and potassium called NaK – have been removed from the primary circuit of the DFR and destroyed over a ten-year period.
Most of the NaK had been removed by 2012, since when work has been under way to remove the last of the coolant from the difficult to access pipework and base of the structure…….
DSRL said the destruction of the DFR’s liquid metal coolant has removed “one of the highest hazards remaining in the Nuclear Decommissioning Authority (NDA) estate”.
NDA chief operating officer Pete Lutwyche said, “The difficulty of this task can’t be understated, and I welcome the news that this work is complete. Everyone involved should be proud of their achievement.”
The focus of decommissioning work at the DFR will now be the removal of some 1000 breeder elements that remain in the reactor vessel, DSRL said. This must be completed before cleaning and removal of the reactor and its nine kilometres of cooling pipework. http://www.world-nuclear-news.org/WR-Coolant-removed-from-Dounreay-Fast-Reactor-0508164.html
The French state-controlled utility is in the process of dismantling nine reactors and has 58 others in operation, supplying France with about 75 percent of its energy needs.
Worldwide, 110 reactors have been halted and will need to be safely dismantled, EDF executives said, adding that the company has a team of 800 experts in the complex process.
“Nuclear decommissioning is a very important market with opportunities for the international and local nuclear sector,” Dominique Miniere, executive director for EDF’s nuclear and thermal plants, told journalists in Paris……
Based on the completed decommissioning of reactors in the United States, EDF estimates that it will cost about 400 million euros to dismantle a 900 megawatt pressurised water reactor — a process that could take up to 15 years.
The company’s first dismantling of a nuclear reactor in France — the Chooz A reactor that ceased operating in 1991 — is expected to be completed in 2022. ($1 = 0.8974 euros) (Editing by David Goodman) http://af.reuters.com/article/energyOilNews/idAFL8N19Q3N4
Who pays for Germany’s nuclear phase-out?,DW Hilke Fischer 1 July 16 Germany’s decision a few years ago to phase out nuclear power was an abrupt move. But it still remains unclear who foots the bill for shutting down the nation’s nuclear plants, as utilities seek damages from the state. Months after a Tsunami resulted in a nuclear disaster at the Fukushima Daiichi plant in Japan, Germany’s coalition government, led by Chancellor Angela Merkel, decided to phase out nuclear power in the country.
Immediately after Fukushima, eight of 17 functioning nuclear plants were shut down, and the government’s decision established a timeline of taking the remaining plants offline by 2022.
Five years later, it’s gradually becoming clear how much this hasty exit could cost. Feeling dispossessed by the move, major utilities have filed a raft of lawsuits claiming damage payments from the government amounting to around 20 billion euros ($22.3 billion).
An eagerly awaited ruling
Complying with the government’s nuclear moratorium, Germany’s biggest energy provider Eon had to shut down its power plants Isar 1 and Unterweser. The company has therefore sued both the federal government as well as the state governments of Bavaria and Lower Saxony, seeking damage payments to the tune of around 380 million euros. The state court of Hanover is expected to deliver its ruling on the case on Monday, July 4………..
the energy companies take issue not only with the moratorium. They – RWE, Eon and Vattenfall – have also lodged numerous cases at the constitutional court in Karlsruhe against the government’s entire policy mandating an accelerated exit from nuclear power……..
State responsible for disposal costs?
Lodging cases before the constitutional court is a pressure tactic, said Green Party politician Oliver Krischer in March. “It’s to obtain concessions over the financing of nuclear waste disposal,” he remarked, pointing to the nuclear commission the government had set up to advise it on how to allocate the costs of storage and disposal of nuclear waste as well as the decommissioning of the power stations.
At the end of April, the commission presented its recommendations: The companies have to bear the costs of decommissioning the nuclear power plants. Furthermore, Eon, RWE, Vattenfall and EnBW are to pay 23.3 billion euros into a fund to manage the storage and disposal of nuclear waste.
In return, the state is to take on all the residual financial risks associated with radioactive waste management. A number of scientists and economists argue that the costs would be much higher than the 23.3 billion euros, and that the taxpayers would be on the hook for those cost overruns.
Germany’s parliament is expected to vote on the recommendations after the summer break, and should it approve them, they would come into force at the end of the year. http://www.dw.com/en/who-pays-for-germanys-nuclear-phase-out/a-19372796

13 JUNE 2016 Consider decommissioning costs before committing to new nuclear power investment
As South Africa prepares to invest in new nuclear power, we may do well to consider the other end of such investment: decommissioning. In the north of Germany, the Greifswald nuclear power plant (also known as Lubmin) has been undergoing the process of decommissioning since 1990. Before its closure, with a total planned capacity of 8 x 400MW plant built, but with only 5 reactors fuelled, Lubmin was to be the largest nuclear power station in East Germany prior to reunification. The reactors were of the VVER-440/V-230 type, or so-called second generation of Soviet-design. When it is concluded, the full process of decommissioning at Lubmin will have taken 30 years from first shutdown. In 1990 the company responsible for decommisioning this 8 x 400MW nuclear power plant, Energiewerke Nord, estimated a cost of half a billion DM per unit. Later this estimate was adjusted to 3.2 billion/unit. Today 4.1 billion/unit is a conservative final estimate (Energiewerke Nord, 2016).
More recently, early in 2012, following the Fukushima disaster in March 2011, the German government announced the immediate withdrawal of the operating licenses of eight German nuclear power plants and revived its plans to phase out nuclear power — by 2022. As this process unfolds, it will be possible to move beyond speculation, to actual data on costs, process and skills required for decommissioning.
What is involved in decommissioning a nuclear power plant?
Nuclear decommissioning is the process whereby a nuclear power plant site as a whole is dismantled to the point that it no longer requires measures for radiation protection to be applied. It is both an administrative and a technical process, including clean-up of all radioactive materials and then progressive demolition of the plant. Once a facility is fully decommissioned it should present no danger of radiation exposure. After a facility has been completely decommissioned, it is released from regulatory control and the plant licensee is no longer responsible for its safety.
The costs of decommissioning are spread over the lifetime of a facility and given that most nuclear power plants operate for over 40 years, funds need to be saved in a decommissioning fund to ensure that future costs are provided for.
What are the current estimates for nuclear power plant decommissioning?
This year, on April 28, an independent commission appointed by the German government (Kommission zur Überprüfung des Kernenergieausstiegs, KFK) presented its recommendations to the Ministry of Economics and Energy. The commission recommended that reactor owners — EnBW, EOn, RWE and Vattenfall — pay an initial sum of €23.3-billion ($26.4-billion) over the next few years, into a state-owned fund set up to cover the costs of decommissioning of the plants and managing radioactive waste. This sum includes a “risk premium” of around 35% to close the gap between provisions and actual costs.
According to the ministry, there will be approximately 10 500 tonnes of used fuel from 23 nuclear power plants, which will need to be stored in about 1 100 containers. A further 300 containers of high- and intermediate-level waste are also expected from the reprocessing of used fuel, as well as 500 containers of used fuel from research and demonstration reactors. In addition, some 600 000 cubic meters of low- and intermediate-level waste will need to be disposed of, including waste from industry, medicine and research.
Just before KFK started its work in October 2015, a study conducted by German audit firm Warth & Klein Grant Thornton for the Ministry of Economics and Energy had estimated the following costs for decommissioning 23 nuclear power plants, in 2014 money i.e. the cost if plants were to be decommissioned in 2014:
- Closure and decommissioning: €19.7-billion
- Containers, transport: €9.9-billon
- Intermediate storage: €5.8-billion
- Final low heat waste storage: €3.75-billion
- Final high active waste storage: €8.3-billion
i.e. a total of €47.5-billion.
However, decommissioning of all of Germany’s 23 nuclear power plants will not be undertaken at the same time. Most costs will be incurred in the future. Annexure 9 of the Warth & Klein Grant Thornton report provides an estimate of likely decommissioning costs when taking into account projected interest rate and inflation scenarios, as well as various likely nuclear-specific cost increases. Their conclusion? Total costs of decommissioning all nuclear power plants in Germany could reach up to €77.4-billion.
Given these emerging figures, even assuming that SA can find the necessary funds needed for new nuclear power investment, we would do well to take into account the increasingly known, non-negotiable related costs of decommissioning and waste management — of both old and new nuclear-related investment.
America’s Nuclear Regulatory Commission set to exempt nuclear corporations from safety costs and liabilities
US nuclear industry’s plan thanks to NRC: let taxpayers carry the can for closed power plants, Ecologist Linda Pentz Gunter13th May 2016 With five reactors closed in the last three years, the US nuclear industry is in shutdown mode, writes Linda Pentz Gunter – and that means big spending on decommissioning. But now the nuclear regulator is set to exempt owners from safety and emergency costs at their closed plants – allowing them to walk away from the costs and liabilities, and palm them onto taxpayers.
Aging and dangerous nuclear power plants are closing. This should be cause for celebration. We will all be safer now, right? Well, not exactly.
US nuclear power plant owners are currently pouring resources into efforts to circumvent the already virtually non-existent regulations for the dismantlement and decommissioning of permanently closed nuclear reactors.
And sad to say, many on the US Nuclear Regulatory Commission (NRC), the industry’s ever compliant lapdog, are trotting happily by their side.
There is an occasional lone critic. NRC Commissioner Jeff Baran, observed that the“NRC does not currently have regulations specifically tailored for this transition from operations to decommissioning. As a result, licensees with reactors transitioning to decommissioning routinely seek exemptions from many of the regulations applicable to operating reactors.”
The inevitable result is that reactor owners will successfully avoid spending money now on decommissioning as they seek to delay beginning the actual cleanup work for the next half century and maybe longer. Later, when it comes time to finish the job, the owners – and the money – could well be long gone.
US reactor owners rely on ‘decommissioning trust fund’ investments to pay for decommissioning activities. But these are failing to accrue adequate funds to do the job. Many of the trusts are incurring annual losses on their investments.
In fact, the US Government Accountability Office (GAO) has found the NRC’s financing formula for decommissioning trust funds to be fundamentally flawed, resulting in the utilities ability to accrue only 57% to 75% of the needed funds……..http://www.theecologist.org/News/news_analysis/2987679/us_nuclear_industrys_plan_thanks_to_nrc_let_taxpayers_carry_the_can_for_closed_power_plants.html
US nuclear industry’s plan thanks to NRC: let taxpayers carry the can for closed power plants, Ecologist Linda Pentz Gunter13th May 2016 “…….There are currently three decommissioning options when a reactor closes. They are known by apparent acronyms that are really just capitalized slogans, masking the flaws behind all three.
DECON refers to prompt dismantlement. This sounds promising for all sides, dispensing with the whole decommissioning process and its attendant costs, headaches and liabilities in about 10 years.
In principle DECON is supported by environmental and anti-nuclear groups, but with one giant caveat: the radioactive waste that remains on site after decommissioning of the reactor, must be adequately safeguarded.
Under the current regulatory scheme, the NRC allows the licensee to offload the irradiated nuclear fuel from the spent fuel storage pools into dry storage casks. These are not adequately protected from security threats. Nor is there any contingency to re-contain nuclear waste should it begin leaking from one of these casks.
Current casks designs are qualified for on-site nuclear waste storage for only 20 years and re-certified for four additional cycles. Some of these cask designs have already experienced degradation of protective seals and concrete shielding after less than a decade of use.
Of greatest concern, the casks are situated outside, closely congregated, on open tarmacs raising security concerns for their vulnerability to attack.
Rather than storing dozens of vulnerable dry-casks right next to each other in the open air, HOSS better secures the nuclear waste in above-ground individualized casks. These casks are fortified within modules of concentric capped silos of concrete and steel surrounded by earthen mounds.
The HOSS canisters would be dispersed over a wider area than traditional cask storage and would be better positioned to withstand a range and combination of weapons, explosives, and attacks, including anti-tank missiles, aircraft impacts, and car bombs.
Currently, reactor owners are not permitted to spend decommissioning funds on nuclear waste management as part of the DECON process. Nor do utilities want to go to the added expense of HOSS, which is not currently being considered by federal agencies, despite hundreds of petitioning groups and thousands of signatories to make HOSS a nuclear security priority at operating reactors as well as decommissioned sites.
A small number of reactors across the world have already used DECON (but without HOSS.) According to the Paris-based Organization of Economic Cooperation and Development, of the nearly 150 nuclear power reactors that have ceased operation worldwide to date, only 16 units have completed the ‘DECON’ decommissioning process with 10 of those units in the United States taking on average 10 years to complete.
What ‘SAFSTOR’ really means: ‘mothball’ and walk away
The second option, euphemistically-named SAFSTOR, or ‘safe store’, allows owners to take up to 60 years from the day the reactor closes to complete decommissioning. This would effectively enable owners to delay the start of decommissioning for 50 years, leaving the reactor and fuel pools mothballed until then and the local communities at risk.
Unsurprisingly, this is the option that is increasingly favored by reactor owners, who are petitioning the NRC for across-the-board cost cutting under SAFSTOR, regardless of the specific conditions of the individual reactor sites.
Entergy Vice President, Michael Twomey, even told Vermont state legislators in reference to the decommissioning of its Vermont Yankee nuclear reactor, that if the process is not complete in 60 years the company is fully within its rights to simply walk away, and if challenged, would litigate. Vermont Yankee closed on December 29, 2014.
The third option is ENTOMB. Without any regulatory guidance or legal framework, it allows utilities to essentially avoid decommissioning altogether. It is the option when no other options exist, as is the case at Chernobyl.
The exploded Chernobyl containment was eventually shrouded in a giant concrete sarcophagus at great expense and resulting in radiological exposure to hundreds of thousands of laborers. That structure is now being encased with a new, high-tech “Arch”, again at vast expense. However, for regular decommissioning activities, ENTOMB should be viewed as a last resort and not as a strategy for escaping liability.
Waste management is nuclear power’s most painful Achilles’ heel
The waste management aspect of the decommissioning process remains the industry’s most painful Achilles’ heel. Despite successfully suing the Department of Energy for failure to remove the waste, as promised, to a final repository site, utilities are seeking to avoid using those funds for waste management.
Instead, utilities are seeking to siphon off decommissioning trust funds to build and manage the necessary on-site Independent Spent Fuel Storage Installation (ISFSI) to house irradiated fuel from a closed reactor. An ISFSI is not currently considered part of a legitimate decommissioning process covered by the trust fund.
The delays wrought by such wrangling means that irradiated fuel sits in densely packed storage pools inside the reactor – and in the case of the 30 remaining GE Mark I and II reactors in the US, on the roof. (The GE designs are the same as those that melted down and exploded at Fukushima.)
The fuel pools are over-packed because of inadequate existing on-site storage facilities. But delays in offloading them, even while the reactor is still running, never mind when it closes, represent one of the greatest risks to public health, safety and security. A catastrophic fire, aircraft impact or other disaster that released vast amounts of radioactive fallout from the high-density storage pools could contaminate entire regions potentially indefinitely.
“The four ongoing disasters at Fukushima Daiichi have clearly shown the vulnerability of nuclear power plants that have spent nuclear fuel stored in these overcrowded and unprotected spent fuel pools”, Gundersen wrote in his comments to the NRC.
Fuel pools at closed US nuclear plants are a Fukushima waiting to happen
This is the principle reason to oppose SAFSTOR, safety experts say. Not only will the fuel remain in the pools, and in poorly protected waste casks, but protections and safety measures will be reduced. This is already exemplified in Vermont where the NRC has allowed Entergy to dismantle its emergency plan around Vermont Yankee and reduce inspections on the ventilation system near the spent fuel pool.
As Gundersen points out, the Vermont Yankee fuel pool still “contains more highly radioactive waste than was held in any of the fuel pools at Fukushima Daiichi.”
With a Fukushima-scale disaster is a real possibility even at closed reactors, critics are urging the NRC not to rubber stamp exemption requests. In the event of a nuclear catastrophe, evacuations downwind and downstream cannot be assumed to go well if emergency preparedness was discontinued months, years, or even decades earlier.
Even plans for site cleanup and decontamination are inadequate and have been watered down by the NRC itself. Site release criteria currently mandate clearing away surface soil down to three feet. But strontium-90 has been found far deeper on the Vermont Yankee site already. The NRC limit would open the way for strontium and potentially other isotopes resting deeper than three feet to migrate down into groundwater and potentially later to drinking water.
Instead, there should be more thorough post-decommissioning environmental analyses of where and how much residual radioactivity has been left behind in soil and water before power companies are allowed to walk away from accountability and liability.
To do decommissioning right, Gundersen argues that the state ratepayers should control decommissioning funds not the utility, because it is their money.
And, he says, decommissioning should be undertaken in such a way that operators “assure that those plants are promptly and safely decommissioned without unwarranted radiological contamination of the environment and extended cleanup and mitigation costs passed on to ratepayers or taxpayers.”

Nuclear reactor sites: Dismantle or fence off? http://www.dw.com/en/nuclear-reactor-sites-dismantle-or-fence-off/a-19111969, 26 Apr 16, Three decades after the Chernobyl disaster, Germany is preparing to go nuclear-free. Industry plans to dismantle and dispose of radioactive waste. But some green campaigners say it’s safer to leave reactor sites as-is.
Thirty years ago, the Chernobyl disaster released radioactivity that spread across much of the northern hemisphere into the atmosphere. It also spurred social movements around the world to demand an end to nuclear power.
In Germany, that end is finally in sight ,as the country prepares to go nuclear-free by 2022. But the task of safely decommissioning and dismantling nuclear power stations promises to be expensive and controversial, and will take many years.
Debate rages over how to dispose of highly radioactive spent fuel rods from commercial nuclear power stations. But there is less awareness around how the dissolving industry and its regulators must also decide what to do with disused reactor sites.
Masses of equipment and a variety of buildings at the sites were exposed to nuclear fission reaction products for years, and have become slightly or moderately radioactive as a result. Therein lies the crux of the disposal problem.
Big money, long time
The consultancy ADL has estimated it will take about two decades to fully dismantle Germany’s 17 nuclear reactor sites, and cost at least 18 billion euros – not including the cost of subsequent radioactive waste disposal.
Why will it take so long and cost so much? DW posed this question to E.ON, Germany’s largest electricity utility and owner of 11 nuclear power stations – most of them already shut down.
An E.ON spokesperson said dismantling of reactor sites must take place in stages. First, spent uranium fuel rods must be transported off-site, to interim storage elsewhere. This can’t happen until four or five years after a reactor is shut down, because the fuel rods’ radioactivity first needs to decrease sufficiently for their safe handling to become possible.
Dismantling equipment is then expected to take 10 to 15 years. Final demolition of remaining buildings and site remediation will take another two to three years after all radioactive materials have been removed from the former reactor site.
Radioactive waste materials can be treated by a variety of means – compression, desiccation, enclosure in cement, or burning to ash – to reduce total volume prior to packing, shipping, and final disposal in an approved secure long-term storage site, E.ON said.
Put it in a deep, dry hole
Schacht Konrad, a disused iron-ore mine shaft near the German town of Salzgitter, is under consideration as the national site for the final disposal of low- to medium-grade radioactive materials.
The mine was chosen because it is particularly dry inside – reducing the risk of radioactive materials dissolving and entering into the groundwater. It’s meant to take in around 90 percent (by volume) of all the radioactive rubble from decontaminated nuclear sites in Germany – but only the mildly radioactive stuff.
German law specifies a threshold of very low radioactivity below which materials are deemed safe. Materials that fall below the threshold can legally be disposed of through the regular waste disposal system. But some anti-nuclear campaigners insist there’s no safe threshold, however low.
In contrast to low-level, mildly radioactive waste from former reactor sites, highly radioactive waste – including spent fuel rods – will be left in cooling ponds on closed-down reactor sites for some decades. Ultimately, they’ll be disposed of in one or more special high-security repositories. The location of those repositories is highly contentious, and has not yet been settled.
Leave them where they’re standing?
While the government and nuclear industry are keen to get on with dismantling and removing reactors soon after they’re shut down, Jörg Schmid and Henrik Paulitz of the German division of the International Physicians for the Prevention of Nuclear War (IPPNW) think perhaps they shouldn’t be dismantled at all.
“Dismantling nuclear reactors is expensive and poses health dangers,” according to an IPPNW report in German published in January of this year.
In the report, Schmid and Paulitz say that serious consideration should be given to the option of securely fencing off old nuclear reactor sites and allowing low-level radioactivity from contaminated buildings and equipment to recede over decades.
The IPPNW’s preferred solution would see heavily contaminated elements such as spent fuel rods be removed immediately, while the less-contaminated buildings and equipment would be left in situ indefinitely.
This would avoid dispersing the radioactive material more widely, and minimize risk to human populations, the study’s authors argue.
E.ON told DW that fencing off sites was neither more nor less safe than dismantling them – but argued that dismantling is a better solution in terms of the labor market consequences.
“IPPNW’s option would mean that 300 to 400 people who work at a nuclear site would abruptly lose their jobs,” the spokesperson said.
But Paulitz countered: “The nuclear industry must answer the question: is the proposed dismantling of the reactor sites a necessary measure, or is it just a new multi-billion-euro industry?”
Radioactive steel in children’s bedrooms?
About 99 percent of the total mass of material at a former nuclear site is radioactive at such a low level that it is deemed safe – so the material is no longer covered by nuclear safety regulations and can be released into the environment, according to IPPNW’s Schmid, who is a medical doctor.
But Schmid said that what matters is total radiation exposure over time. If very large amounts of very weakly radioactive material are dispersed through the environment, for example by being reintroduced into material supply chains, that represents a significant amount of broadcast radiation exposure over time.
Dismantling nuclear power plants, Paulitz said, leads to a problem: “The great majority of the site’s materials won’t be classified as nuclear waste, and will instead be disposed of in ordinary household waste streams, or even recycled into normal supply chains.”
“From a health and safety perspective, we see this as irresponsible.” Paulitz said, as weakly radioactive steel taken from a dismantled nuclear site could end up built into a radiator in a child’s bedroom, for example.
Nuclear costs in uncharted territory http://www.eco-business.com/news/nuclear-costs-in-uncharted-territory/ As some governments press on with new nuclear installations to address climate change, a multi-billion dollar industry will be needed to make safe old power plants and their hazardous waste. Climate News Network 19 April 2016 If you want a job for life, go into the nuclear industry – not building power plants, but taking them down and making them safe, along with highly-radioactive spent fuel and other hazardous waste involved.
The market for decommissioning nuclear sites is unbelievably large. Sixteen nations in Europe alone face a €253 billion waste bill, and the continent has only just begun to tackle the problem.
Among the many difficulties the industry faces is lack of trained people to do the highly-paid work. Anyone who enters the business is likely to be sought after for the rest of their career because the job of decommissioning Europe’s nuclear sites alone will take more than 100 years – even if no new nuclear power stations are ever built.
Add to the European nuclear legacy the dozens of old nuclear power stations in North America, Japan, Russia and central Asia, and nuclear decommissioning could already be classed as one of the biggest industries in the world, and it can only grow.
So far, the nuclear industry has largely avoided drawing too much attention to this legacy, emphasising that its sites are safe, and concentrating instead on claiming that new nuclear stations are the answer to climate change.
But this approach has not solved the longer-term problem of how to safely contain the radioactivity of old sites to avoid damaging future generations.
The UK, one of the countries with the largest nuclear waste problem, is also currently spending most money trying to make it safe. One site alone − Sellafieldin Cumbria, northwest England − is spending £2 billion a year on cleaning up its waste and expects the total bill to be around £50 billion.
But that is almost certain to rise. There are 240 operational nuclear buildings on the site, and 11 major construction projects aimed at containing the waste problem.
Twelve other old nuclear sites in the UK, where reactors have already been shut down, are costing £600 million a year to clean up, a process that will take until 2027.
Even then, the job will not be finished. All that money will have been spent on reducing the hulks to a “care and maintenance basis” so they can be guarded for decades until it is decided to demolish them altogether when it is safe to do so.
It is probably because the UK is spending so much money already that theNuclear Decommissioning Conference for Europe is being held in the northern England city of Manchester on May 31 to June 1. All the major nuclear companies in Europe, and many international businesses hoping to cash in on this new industry, will be attending.
But the UK is only one major market, and France is potentially even larger. Although it has not yet decommissioned its nuclear stations, it is about to start doing so and has 58 reactors to dismantle. Germany, like the UK, has already begun its programme, with nine reactors shut down and another eight to be closed by 2022.
In total, there are 200 reactors worldwide due to be shut down by 2025.
But while the primary task of the current decommissioning programme is to make reactors safe by removing their old fuel and storing it, one of the major problems of the industry is nowhere near solved.
All over the world, governments have tried and failed to find sites where they can store the vast quantities of radioactive waste that has arisen from nuclear weapons programmes, nuclear submarine and ship propulsion systems, and the civil nuclear industry. The waste needs to be isolated from human beings for as much as 250,000 years to make it safe.
Only one country, Sweden, has a workable plan for a deep disposal repository. Elsewhere, many plans have been tried and abandoned, either because of political opposition or unfavourable geology.
So nobody knows yet how much this epic problem is going to cost, or how many decades will pass before it is under control. As the brochure for the conference puts it: “Estimating lifetime costs is a journey into uncharted territory.” No wonder executives from many companies are paying up to £1,500 each to attend.
Nuclear reactor clean-up weighs on EDF, FT.com, 19 Apr 16, Michael Stothard in Paris French utility faces questions about whether it has set aside enough to decommission power plants
In 1997 French utility EDF started to dismantle its first nuclear power plant, a 30-year-old heavy water reactor in Brennilis, north-western France. It was expected to cost €250m.
The bill is now set to be at least half as much again, and the decommissioning is still not done. In fact, there has never been a full dismantling of a reactor in France, the only European country to get three-quarters of its electricity from nuclear power.
EDF, the operator of all 58 of France’s reactors, is preparing to build a new £18bn plant at Hinkley Point in the UK that some at the Paris-based company have warned is too dangerous given its stretched balance sheet. EDF’s other big reactor project, at Flamanville in France, is already six years behind schedule and €7.2bn over budget.
Hinkley and Flamanville have focused attention on another looming challenge for EDF: has the company set aside enough money to cover the huge cost of dismantling and cleaning up its existing nuclear power stations in France?
Unlike the UK, where the state has assumed much of the financial risk of taking apart nuclear reactors, in France it all falls on EDF, which has established a €23bn special fund for this purpose.
The €23bn — much of it invested in equities and bonds — has been set aside to cover what EDF estimates will be the €54bn cost of decommissioning the 58 reactors and safely storing their radioactive waste. This includes €23bn for dismantling the power stations, and €26bn for managing spent fuel………..
EDF faces several major investments. As well as the £18bn Hinkley Point project, EDF is involved in bailing out reactor designer Areva by buying a controlling stake in its reactor business for €2.5bn. It is also extending the life of France’s existing nuclear power stations until 2025, at a cost of €55bn.
And it is not just the decommissioning of the 58 reactors that is of concern. The estimated cost of storing radioactive waste — potentially for thousands of years — has been steadily rising………..http://www.ft.com/cms/s/0/c82ae2c4-0582-11e6-9b51-0fb5e65703ce.html#axzz46IzsG72i
This failed $5.3 billion nuclear power plant in Germany is now an amusement park that gets hundreds of thousands of visitors each year (great photos) http://www.businessinsider.com/nuclear-power-plant-into-amusement-park-2016-4/?r=AU&IR=TCourtney Verrill
The SNR-300 was supposed to be Germany’s first fast breeder nuclear reactor when construction began in 1972. The reactor was made to use plutonium as fuel, and it would output 327 megawatts of energy.
Built in Kalkar, the government had some concerns about the safety of the nuclear reactor, which delayed construction. The power plant was finished in 1985 — $5.3 billion later.
But after the Chernobyl disaster in 1986, the SNR-300 never got a chance to fully operate, and by 1991 the project was officially canceled.
This left the power plant completely unused, and it was eventually sold to a Dutch investor who decided to turn it into an amusement park: Wunderland Kalkar.
O.C. Watchdog: Could there be an ‘early’ nuclear cleanup at San Onofre? Orange County Register, By TERI SFORZA / March 23, 2016 Federal efforts to speed up the removal of spent radioactive fuel from power plants like the mothballed San Onofre Nuclear Generating Station are gaining momentum and inspiring guarded optimism among local officials.
Critics, however, remain deeply skeptical.
In January, the U.S. Department of Energy launched a new push to create temporary nuclear waste storage sites in regions eager for the business, currently in West Texas and New Mexico.
Several such sites could be up and running while the prickly question of finding a location for a permanent repository – the root of the present paralysis in nuclear waste disposal – is hashed out.
“That could mean moving the fuel from San Onofre a decade earlier than is envisioned now, maybe more,” said David Victor, who chairs the San Onofre Community Engagement Panel. The volunteer group of academic, industry, environmental and local government representatives advises the plant’s owner, Southern California Edison.
“I am cautiously optimistic,” he said. Victor, director of the Laboratory on International Law and Regulation at UC San Diego, met with officials in Washington this month to convey populous Southern California’s eagerness to solve the nuclear waste storage problem. An update on those efforts, as well as the latest on plans to dismantle the shuttered twin reactors, will be presented at 6 p.m. today at the San Onofre Community Engagement Panel’s quarterly meeting in Oceanside.
Decommissioning the plant south of San Clemente is expected to cost $4.1 billion and be mostly completed by 2030. But spent nuclear fuel is expected to remain on the beachside bluff much longer………… http://www.ocregister.com/articles/fuel-709466-nuclear-san.html
Commentary on report: The Nationwide Failures of Decommissioning Regulation: Decommissioning Trust Funds or Slush Funds?

MiningAwareness, 24 Mar 16 After so many years rats can set up and spread contamination. However, where will they be decommissioned to? While the rats are a problem, letting the reactors sit up does actually allow some of it to become less radioactive. Some period of letting it sit up also allows time for a real solution, if there is any outside of a 24/7 monitored bunker.
A few years would allow construction of such a facility. Certainly Vermont is happy to send its large nuclear parts to sit outside and be buried at the Clive facility in Utah or West Texas.
Who wouldn’t be happy to get shot of this lethal waste? Eventually it’s going to come back up from its burial ground and land on the eastern states too. To be fair I haven’t read this document. However, I think that Vermont’s “waste pact” is with west Texas, WCS (Waste Control Specialists).
Although Vermont may not be suitable for radioactive waste due to rain, west Texas is unsuitable due to heat and alternating rain and dry spells, in conjunction with burial in concrete lined clay. Plus it’s hard to see the fairness in this, except there is a good chance that the rain out following the inevitable explosion at WCS will be over Vermont. Burial of waste is unacceptable everywhere. And, that’s what they do at WCS and Clive.
It’s easy to see people in the eastern US think that what happens out west has nothing to do with them, but weapons testing proved otherwise. Interestingly, if German nuclear waste is buried in South Carolina, rather than further west, Germany may be more impacted by the inevitable explosion than the US. Certainly Europe may be. But, like Europe’s unwanted people, the movement of the waste will be gradually westward.
The Nationwide Failures of Decommissioning Regulation: Decommissioning Trust Funds or Slush Funds? http://www.fairewinds.org/nuclear-energy-education//03tj9289ut746v9sb3cbkrhfzqgtdzFairewinds Energy Education has submitted a new decommissioning report entitled: The Nationwide Failures of Decommissioning Regulation: Decommissioning Trust Funds or Slush Funds? to the Nuclear Regulatory Commission (NRC). Research was funded by a Lintilhac Foundation Grant. First submitted a year ago, the report evaluates utility owner Entergy’s plan to use the NRC sanctioned SAFSTOR process to decommission Vermont Yankee.
Developed by the NRC, SAFSTOR is a subsidy that benefits nuclear power plant owners like Entergy by providing them with a 60-year window to decommission nuclear plants. With an increasing number of aging atomic power plants shutting down in the United States, Fairewinds’ report is an ongoing case study of the decommissioning process at Vermont Yankee where nuclear energy corporations have been allowed by the NRC to raid decommissioning funds procured by ratepayers like you and me. From unregulated withdrawals of funds, a 60-year timeline with no basis in science, to zero responsibility in regards to emergency planning, it’s clear that NRC regulations are benefitting corporations and not the public.

Nuclear commission proposes firms transfer cash by 2022 to pay for clean-up http://af.reuters.com/article/commoditiesNews/idAFB4N10000F
Mon Feb 22, 2016BERLIN Feb 22 (Reuters) – Germany’s utilities will have to transfer provisions set aside to pay for the interim and final storage of nuclear waste to a fund in cash by 2022, according to a draft report from a government-appointed committee seen by Reuters on Monday.
The report recommends that Germany’s “big four” utilities — E.ON, RWE, EnBW and Vattenfall — remain liable for the cost of up to double the 18 billion euros ($19.8 billion) allocated so far to pay for interim and final storage.
The companies will also have to set aside a further 1.3 billion euros in provisions, according to the report which is due to be presented at the end of the month. ($1 = 0.9084 euros) (Reporting by Markus Wacket; Writing by Caroline Copley; Editing by Christoph Steitz)
