Application Prospect Analysis of Probabilistic Safety Analysis(PSA)in High-level Liquid Waste(HLLW)Separation System
High-level waste liquid(HLLW)concentrates more than 95%of the radioactivity in spent fuel,and its proper treatment and disposal is one of the key factors affecting the sustainable development of the nuclear fuel cycle.The TRPO process proposed by Chinese scientist can effectively separate actinides and fission products in HLLW,and after more than 40 years of development,a good engineering application foundation has been built.However,its safety analysis is still relatively lacking,as a new type of nuclear chemical system.In this paper,the method path that can be taken for the safety analysis of the high-level separation system is analyzed,and the prospect of the application of the probabilistic safety analysis(PSA)method in HLLW separation system is further prospected,based on the feature analysis of the high-level separation system,and combined with the practice and research of other relevant system security analysis.
