CEG-Newsletter (September 2013) Germany Regional Centre for Conditioning and Long Term Storage The construction of the Regional Centre for Radioactive Waste Conditioning and Long Term Storage, including the dismantlement shop, is carried out on time and is currently at the completion phase. The façade and roofing will be finished in October. Inner engineering systems are being installed (heating, ventilation, water supply, sewage, electric power, lighting, low voltage and special systems). Regional Centre for Radioactive Waste Conditioning and Long Term Storage Façade installation on the workshop 30 Boiler room Engineering network Ventilation system Power control board In addition to the construction work, the manufacturing of technological and special equipment for caissons of radioactive waste management is being completed. This includes the equipment for cutting, waste conditioning, decontamination and final radiation control. Their transportation and installation at the Centre will start in autumn 2013. The electric power equipment of the Centre (transformers, emergency diesel generators, batteries, power control systems for 6kV and 0.4 kV) has been manufactured in Germany, installed at the site and connected to the power supply line. The cranes have been manufactured in Russia and supplied to the Centre. The equipment for treatment of liquid radioactive waste and a facility for sorting and packing medium level solid radioactive waste have been manufactured and currently are being supplied to the site. An approach road to Saida Bay is also being built. Road building Completion and commissioning of the Regional Centre for Radioactive Waste Conditioning and Long Term Storage is planned for December 2014. France and Russia 100t crane at Atomflot The French government is funding the mounting of a new 100t crane at Atomflot (purchased by Russia in Finland). The work is to be completed in autumn, and its licencing and commissioning is scheduled for the end of 2013. This will be an important infrastructural element at Atomflot for spent nuclear fuel transhipment to the Mayak plant. Refurbishment of the Hot Cell at Mayak Plant The delivery of tools and equipment for the hot cell is underway and the assembly work started in autumn 2012. The refurbishment of the hot cell will be finished by the end of 2013. This cell is destined for treating damaged spent fuel assemblies from Gremikha, Andreeva Bay and also Sysoyeva Bay in the Russian Far-East. Projects in Gremikha Studies have been carried out of long term storage for Alpha type SNF (up to 10 years storage) with cassettes of fuel in canisters placed in the TUK-108/1 casks. It was recommended as a good practice to fill up the canisters with argon inert gas, which has been effectively done In the course of this work, a valuable experience was gained that will be used for dismantling the remaining spent reactor cores. The acquired knowledge is already used in the development of design drawings for the dismantlement project of reactor core # 910, where most of equipment from defueling the #900 will be reused. Some new equipment might be required for disassembling the cassettes with SNF, where local alloy oxides might occur, to avoid possible sticking of SNF assemblies in the holes of the lower plate during the lifting process. Overhaul works on Gremikha’s infrastructure have been done in 2013, particularly on systems and mechanisms of the SD-10 dry dock. In addition, a new 20t bridge crane was commissioned and a monitoring system is under installation on 75t bridge crane. Italy Andreeva Bay RW management project The Design Documentation (DDA) for the liquid treatment plant and container storage facility was completed and sent to GlavGosExpertiza (GGE) in February 2013. The DDA for storage facility has met all standards of GGE, while in relation to Liquid treatment plant GGE has released a set of comments, most of which were related to new ecological regulation in Russian Federation which went into force in April 2013. The new submission of DDA for the liquid treatment plant will be done until the end of September 2013. The open tender for the storage facility will be announced by September-October 2013, and for the liquid treatment facility by first quarter of 2014. Both tenders will be open to Russian suppliers. Solid RW treatment facility. In accordance with a recommendation of Rosatom, it was decided to provide remotely controlled equipment for waste retrieval from the already completed buildings 201 and 202. Waste characterization, sorting, preliminary treatment (decontamination, cutting and loading into 20” containers) will follow. These containers will be transported to Sayda Bay for final conditioning. Currently SOGIN and SevRAO are working on preparation of the list of needed equipment and related technical specification. The tender for equipment supply will be presumably launched in the first quarter of 2014. Physical protection of the Rossita ship The installation and testing of physical protection equipment will be completed in September- October 2013, after that the ship will be ready to start waste transfer operations. Currently Rosatom and Atomflot are preparing a perspective plan for using the ship. Alfa core casks contract The delivery of first container to Russia is expected in January-February 2014; the remaining 9 containers will follow; the last container will be delivered in the third quarter of 2014. The contract for certification is now under discussion between Italian and Russian parties Welding operations of the first container for alpha reactor cores Contract for the pontoon for shipment of submarine reactor units to Saida The dossier for the pontoon contract has been completed and agreed among the contractual parties; the contract is expected to be signed in September 2013. Dismantlement of the Oscar class submarine In November 2012 Italy signed a contract for dismantlement of one more nuclear submarine, an Oscar #617 in cooperation with Rosatom and USA. This is the sixth submarine dismantlement financed by Italy. The third phase of the contract (defueling) was completed in May 2013. In accordance with a decision of the Russian side the defueling has been done not with PM-12 of the Russian Navy but with “Imandra” Ship and floating Crane “Chernomorets” of Atomflot. Fuel discharge from the Oscar 617 nuclear submarine under dismantlement Japan The construction of the Blast and Paint Facility for reactor compartments at DalRAO is steadily progressing. Japanese delegations have made two inspections of the site. The facility is to be completed in December 2013. Norway Cooperation agreement with the Russian Ministry of Defense Norway and Russia continue their successful cooperation in securing and preparations for removing spent nuclear fuel and radioactive waste in Andreyeva Bay. On 20 March the Norwegian Radiation Protection Authority (NRPA) prolonged its cooperation agreement with the Russian Ministry of Defense (MOD) in this field. According to the agreement, the short-term safety cooperation will be tied to specific clean-up projects, while the long-term cooperation will focus more on general support to various Russian authorities, building relations, safety culture and interaction with more open processes. The NRPA has collaborated with the Russian MOD for years on regulating and improving nuclear and radiation safety in this area. Revised nuclear action plan The Norwegian Government nuclear action plan for nuclear activities and the environment in northern areas was revised in 2013. The action plan was launched in April 1995, and has been revised four times. The main focus of activities is nuclear clean-up in Andreeva Bay, along with environmental monitoring in the Barents and Kara Seas. Independent evaluation of the Norwegian RTG project in NV-Russia Between 2001 and 2009 Norway financed the removal, handling and transport of 180 RTGs from Northwest-Russia. The project has been evaluated as to the effectiveness of project management, as well as improvement in radiation safety, radiation security and environmental protection. The evaluation was finalized in January 2013 and the conclusions are that Norwegian funding has been instrumental in ensuring that the removal, handling and transport of the RTGs took place without any reported serious events with subsequent release of radioactivity to the environment or uncontrolled exposure to people. Improvements in radiation safety, security and environmental protection have been achieved. In connection with the completion of the Norwegian-Russian project to remove RTGs from the Russian part of the Baltic Sea, the Office of County Governor of Finnmark and NRPA visited the NIITFA Institute and the Mayak Plant to perform the final project inspection of handling these sources. Cooperation with FSUE Atomflot Cooperation in the areas of Environmental Monitoring and Nuclear Safety has been initiated with FSUE Atomflot. Projects focused on improving environmental monitoring, nuclear and fire safety of icebreakers and units located on the coastal territory of FSUE Atomflot are under development in cooperation between Institute for Energy Technology (IFE) and FSUE Atomflot. NDEP nuclear window projects carried out by EBRD Dismantlement of the Lepse floating maintenance base Lepse was transported to Nerpa Shipyard (Kola Peninsula) in September 2012 and is berthed there with stringent safety and security measures in place, including radiation monitoring and physical protection. A contract has been placed for preparatory
