UK & US regulators: unresolved safety issues EPR and AP1000.
On November 10, the UK nuclear regulator said it expects both the Areva EPR and the Westinghouse AP1000 reactors to have unresolved safety issues when the generic design assessment, or GDA, program completes next year. In a quarterly progress report, the NII said it has potential open issues in 10 out of 18 topical areas on the Areva EPR design review and in 16 out of the 18 topical areas on the Westinghouse AP1000 design. The GDA program was set up to issue design acceptance confirmations, or DACs, to the reactor vendors, which would see the regulator sign off on all but site specific licensing issues. The DAC could then be referenced in site license applications by utilities building the reactors. But the program has been plagued by delays resulting from NII Staff shortages and "a failure on the part of the reactor vendors to satisfy the regulator's queries", as Platts puts it.

A day earlier, World Nuclear News reported that Westinghouse has been told by the U.S. NRC that it's AP1000 aircraft impact study is not adequate. The Nuclear Regulatory Commission said that documents put to it in order to demonstrate a 2009 requirement did not include 'realistic' analyses and that this amounted to a violation of requirements that Westinghouse must explain and rectify. A rule introduced by NRC in 2009 states that  new nuclear power plant buildings and safety systems must maintain containment, cooling of the reactor core and the integrity or cooling of used fuel facilities in the event of the impact of a large passenger jet. All reactor vendors must fulfill this requirement for their designs. For Westinghouse this regulatory work comes in addition to a 2007 design amendment to the original AP1000 design, which was certified by the NRC in 2006.

In February, UK regulators already criticized the "long delays" and "poor quality" of replies they received from Westinghouse and Areva following safety reviews of their reactor designs.

Update Belene, Bulgaria
The situation around the planned nuclear power station in Belene in Bulgaria has become unclear again. Under heavy Russian pressure (among others directly from Prime Minister Putin) and political pressure from a faction within his own party GERB around the Parliament Chair Tsetska Tsacheva, Bulgarian Prime Minister Boyko Borisov declared he is dedicated to the construction of the power plant on the shores of the Danube. Russian Atomstroyexport, a part of Rosatom, prolonged the construction contract with half a year under the condition of a price increase of maximally 2,5 billion Euro on top of the initial 4 Billion price tag. According former director of the Bulgarian Nuclear Regulatory Agency and current professor in risk analysis at the university of Vienna, Georghi Kashchiev, during a round table discussion on 18 October in Sofia, this does, however, not include the first load and large parts of the non-nuclear equipment. With that, the demand from Borisov that the total cost of the project remain under 7 billion Euro come under severe pressure. It is also unclear whether the 500 Million Euro already sunk into Belene are part of this budget. On 1 November, Bulgaria's finance minister Simeon Djankov once more confirmed that no state finances would flow into the project.

In a surprise move, Prime Minister Borisov declared on 25 October after a visit to Muenich a week earlier, that he had found a strategic investor from Bavaria for Belene. Bulgarian media speculate interest from Siemens, the engineering firm that recently broke its alliance with Areva and partnered instead with Rosatom. Siemens, however, refuses to comment on these speculations. An announcement from the Bulgarian Ministry of Economy, Energy and Tourism that the new strategic investor would be announced in the first week of November was not realised, however, and German media have remained suspiciously silent about a possible deal. On 5 November, Borisov announced an offer of up to 2% participation to each Serbia and Croatia in what he said was a pragmatic attempt to secure markets for the output of Belene.

… and Mochovce, Slovakia

Slovakia has asked and received an extension of the period of comment on the draft verdict of the Aarhus Convention Compliance Committee, that the Environmental Impact Assessment for the Mochovce 3,4 project has violated the rules of the Convention. The NGOs that originally filed the complaint, Za Matku Zem, Greenpeace Slovakia, Global2000 and the Oeko-buero Wien, did not object to an extension to 30 November. The ACCC is expected to come with a final verdict in December. A spokesperson of the Slovak nuclear regulator UJD, which was responsible for issuing construction licenses in spite of the fact that the EIA procedure had not been finalised, is currently looking for possibilities to implement a likely final verdict of the ACCC, but stated to Greenpeace that it has problems finding a proper legal pathway to do so.

An ACCC verdict is, however, binding and a breach of the Aarhus Convention is also a breach of EU legislation on Environmental Impact Assessments, which means that the European Commission would be obliged to start corrective procedures against Slovakia in case the ACCC verdict concludes a violation of the rules.

… and Temelin, Czech Republic

The submission date for the tender for five new nuclear power stations issued by the Czech utility CEZ has been extended with a year to 2013. CEZ argued that some of the contenders had asked for such an extension, though analysts are of the opinion that the lack of growth in electricity demand in the Czech Republic has bitten into the economic viability of the project. The tender for five blocks, two for Temelin and one for Dukovany in the Czech Republic, one for Jaslovske Bohunice in Slovakia and one for a still to be decided project is expected to cost around 500 billion Czech Crowns or 25 billion Euro. Each block is supposed to deliver between 1000 and 1600 MW capacity.

Another fiasco at Monju, Japan.
A12-meter-long, 46-centimeter-wide, 3.3-metric-ton heavy fuel exchange component that lodged in the reactor vessel of the Monju fast-breeder reactor after being dropped on August 26, cannot be extracted using "usual methods," the Japan  Atomic Energy Agency (JAEA) has stated. The JAEA made the announcement November 9, after examining the component -a cylinder now stuck in an opening in the reactor vessel cap- with a camera. The agency believes that to get the part out, equipment on the reactor vessel cap will have to be removed, and an entirely new structure built to prevent sodium now covering the cylinder from mixing with the outside air and igniting during the process. The agency is now considering ways to do this, but gave no hint when testing of the reactor may recommence.

Since Monju resumed test operations on May 6 after shut down since a 1995 sodium leak, it has undergone the first stage of testing. These core confirmation tests were completed on July 22. Preparations were being made for the next stage, which involves increasing power output to 40%, planned for July 2011. However,  the jammed relay cylinder has made further long delays probable.

UK: What 'no subsidies' means: more help will be given.
Following lobbying by the nuclear industry the Government has accepted that it needs to give more financial incentives in order to ensure a new generation of reactors are built in the UK. Energy minister Charles Hendry said he now agreed with the industry that fixing a high minimum price for carbon emissions was not enough. Instead he thought other financial incentive measures would be need to encourage nuclear and other low-carbon energy sources.

IEA: US$312 billion subsidy annually for fossil.
On November 10, the International Energy Agency published its World Energy Outlook 2010. The IEA report clearly states that fossil fuels are heavily subsidized by more than US$312 billion per year globally! This leads obviously to unfair competition with clean and climate friendly renewable energies. IEA is increasingly recognizing the important role renewable energy can play to fight climate change and improve security of supply. However, it is failing to shift technology recommendations from unproven, dangerous and expensive technologies such as CCS and nuclear power plants.
