Study on Mitigation Strategy of AP1000 Spent Fuel Pool Exterior Disaster

After Fukushima nuclear accident, much attention has been paid to the safety of the spent fuel pool (SFP). AP1000 spent fuel pool cooling system (SPS) is not a safety related system. It is not designed for design basis accident. But the safety of SFP in exterior disaster and severe accident is very important. The extensive damage mitigation guidelines (EDMG) of NEI to AP1000 SFP accident mitigation was studied, including internal strategy and external strategy. The results are useful for design AP1000 nuclear power plant and the mitigation when SFP exterior disaster happens.
