新型乏燃料贮存格架自主研制

Independent Development of a New-Style Spent Fuel Storage Rack

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。

A new type of spent fuel storage rack is developed independently. Based on the structure of the spent fuel storage rack, this paper demonstrates the security and reliability in terms of the criticality safety, thermal hydraulic and seismic analysis. In order to verify the design rationality and manufacturing feasibility of the spent fuel storage rack, a prototype is manufactured, and the supporting leg adjustment test and the mock-up fuel insertion test are carried out. The prototype manufacturing and test showed that the design is reasonable, the manufacture is feasible, and the new type of spent fuel storage rack can be fabricated in mass production.
