Spent Fuel Pool Probability Safety Assessment of Fujian Fuqing Phase 1 Nuclear Power Plant

Spent fuel pool probability safety assessment (PSA) for Fujian Fuqing Phase 1 Nuclear Power Plant was studied. PSA for different internal initiating events to be possible to threaten the safety of spent fuel pool was conducted to evaluate the risk of fuel damage in spent fuel pool. The designs of improvement including emergency makeup and continuous level monitor were also evaluated. The result shows that comparing with traditional design, implementation of the improvement can significantly reduce the fuel damage risk of spent fuel pool.
