Simulation and Analysis of Loss-of-Coolant Accident in Cold Leg of PWR Based on ATHLET and SIMIS

摘要

An accident safety analysis of small break loss of coolant is needed in order to avoiding the loss of coolant accident due to inadequate cooling in the reactor core and the leak of radioactive after the small break in primary circuit. We analyze the small break loss of coolant accident in cold leg of PWR primary coolant system by using Daya Bay 1000 MW nuclear power plant simulation system. Then we compare the result with another result which simulated by the software named ATHLET and verify the accuracy about simulation system.
