1 Personal information Anton Leshchenko (Russian Federation) graduated from Technical University in N.Novgorod, specialized in radiophysics; Senior Researcher at Fuel Research Department at Research Institute of Atomic Reactors; Leading Researcher of Federal Unitary Enterprise «Nuclear and Radiation Safety»; 2010-now Deputy Head of Research Department of «Sosny» Company; PhD since Experience: Post irradiation examination of fuel, Examination of spent fuel behavior under LOCA and quench conditions, Examination of thermo-physical properties of nuclear materials, Safety assessment analysis (including damaged SNF management), R&D project management. 1

2 Profile of R&D Company Sosny Manage SNF including damaged SNF. Develop SNF handling technologies, design, fabricate and assemble equipment. Design automated systems for technological process control and dose rate monitoring, video systems, communication systems, nuclear material and RAW account and control. Transport SNF and radioactive substances. Design transport equipment. Certify casks. Perform research and development work, develop scientific and methodical basis for safe SNF management in the process of storage, transportation and reprocessing; arrange and support experimental and research activities to examine properties of reactor materials in cooperation with Research Institute of Atomic Reactors; perform analysis of technical decisions and safety assessment of radioactive material management. 2

3 Related experiences (1) Elimination of the consequences of damage of VVER-440 SFA in the cleaning tank of Paks NPP (Hungary) Design the working frame to remove damaged SNF. Design equipment and tools to handle different types of SFA fragments (more than 100 units). Design untight canisters filled with water with the compensator to ensure removal of fission gas and radiolysis products and prevent release of radionuclides dissolved in water from canisters. Design support equipment, video systems and dose rate monitoring systems. Perform R&D work, design technologies and equipment for drying canisters to transport SNF to the reprocessing or dry storage facility. Perform practical work on elimination of the consequences of SNF damage. As a result more than 5 tons of damaged SNF was removed from the cleaning tank. 3

4 Related experiences (2) Removal of RR SFA from Vinca Institute (Serbia) Design special technologies of damaged SNF repackaging and preparation for shipment. Perform safety assessment. Fabricate and assemble equipment at the reactor. Repackage SNF into canisters. Design technology and equipment to load canisters with SNF into casks. Develop Unified Project documents to import SNF into the RF. Load canisters into transport casks, transport SNF into Russia for reprocessing at PA Mayak. As a result almost 2,5 tons of damaged SNF was removed. Preparation of SNF of AMB-100 and AMB-200 reactors for shipment to the reprocessing facility (Russia) Principal technology for handling AMB SNF at Beloyarskaya NPP was designed; a number of designing and experimental activities were performed to ensure SNF storage safety; conceptual design of equipment to transport SNF for reprocessing and sections of the technology for accepting and handling AMB SNF at PA Mayak reprocessing facility were developed. 4

5 Related experiences (3) Enhancement of storage safety of accumulated SNF of EGP-6 reactors of Bilibinskaya NPP (Russia) Perform inspection of SNF storage pools, design of baskets for packaging SFA and equipment for SNF management including automated SNF cutting facility at Bilibinskaya NPP. Preparation and removal of SNF from FSUE SSC RF-IPPE (Russia) Design and fabricate canisters to place SFA and equipment to cut and package SFA into canisters. The first batch of canisters with SFA was delivered to PA Mayak for reprocessing. 5
