Abstract

Abstract

A preliminary study on the safety analysis technology of space nuclear power sources was conducted using the Probabilistic Safety Analysis (PSA) method to address a series of new issues brought about by the characteristics of weak redundancy and diversity, non-maintainability, high mobility, and experiencing multiple mission phases during their lifespan. Based on a thorough analysis of the special safety requirements of each mission phase, a comprehensive safety goal system suitable for space nuclear power sources was constructed. Research has shown that the safety assessment of space nuclear power sources still faces many technical challenges. For China, conducting safety assessment technology research on space nuclear power sources in parallel with the design phase will help improve the design efficiency and enhance the safety of space nuclear power sources.
