Spent fuel storage rack is one of the key equipments of nuclear power plant to store the spent fuels. In order to real-ize self-reliant design of the SNG spent fuel storage rack, the design of American third generation nuclear power technology AP1000 spent fuel storage rack has been consulted, and combined with the design experience in domestic related with the spent fuel storage rack, design of the rack has been optimized. Localization of this equipment has been realized. Especially, the neutron absorber has been independtly developed and all the safety-related analysis of the rack have been accomplished and the experiments are being performed. The storage capacity, the results of criticality analysis, the anti-seismic analysis and thermal hydraulic analysis would all meet the requirements of related regulations and standards of China.
