自主研发一种新型乏燃料贮存格架。基于该乏燃料贮存格架的结构,从临界安全、热工水力和力学抗震等方面论证新型乏燃料贮存格架的安全性、可靠性。为了验证新型乏燃料贮存格架的设计合理性和制造工艺可行性,制造1台工程样机,并进行支腿调节试验和模拟组件插拔试验。通过样机的制造和试验表明,新型乏燃料贮存格架设计合理、制造可行,可以批量化生产。 Independent research and development of a new type of spent fuel storage grid. Based on the structure of the spent fuel storage grid, the safety and reliability of the new spent fuel storage grid are demonstrated from the aspects of critical safety, thermal hydraulic and mechanical seismic resistance. In order to verify the design rationality of the new spent fuel storage grid and the feasibility of the manufacturing process, a prototype of the project was manufactured, and the outrigger adjustment test and the simulation module plug-in test were conducted. Through the prototype manufacturing and testing shows that the new spent fuel storage rack design is reasonable, manufacturing feasible, mass production.
