Information × Registration Number 0211U013607, 0110U005933 , R & D reports Title Development of VVER fuel assembly input models for HELIOS code and their validation for the purpose of introduction in expert practice of UNRCU to enhance safety quality assessment in the time of VVER operation popup.stage_title Head Kuchin Alexandr Victorovich, Registration Date 29-12-2011 Organization State enterprise "State Scientific and Technical Center on Nuclear and Radiation Safety" popup.description2 Subject - the code HELIOS regarding calculation of microstructure of power distribution in VVER fuel assembly cross-section and preparation of cross section library for code DYN3D for VVER physical calculation. Goal - the increase of quality of nuclear safety assessment performed by State Scientific and Technical Center for Nuclear and Radiation Safety (SSTC NRS) of given by Utilities materials for substantiation of: operation of fuel loadings; implementation of new fuel types at Ukrainian NPPs; introduction of new unit ins Ukraine, that is provided technical support of Regulatory Committee during a making of correct decision regarding licensure on VVER reactor core operation from point of view nuclear safety assessment. The method of research- analytical. A testing of VVER-1000 fuel assembly's calculation model for code HELIOS have been performed on example of comparative analysis with results of well-known benchmark in the frame of first stage. Development of additional blocks to computation code DYN3D have been performed with the purpose of using additional capabilities of code HELIOS to increase accuracy of prediction of VVER-1000 reactor core neutron-physical characteristics.The goal of the second stage is development of methodology and program for parameterization of few-group cross section of DYN3D program, few-group cross section library preparation using HELIOS code to their further use in the DYN3D program with VVER-440, 1000 fuel, carrying out of validation calculations of fuel campaigns and comparing the obtained results of calculation with both operational data and the results of calculations obtained using other programs.
