Equipment Testing for Severe Accident Conditions
Original language description
The operational states of a nuclear power plant can be generally categorized as normal operation and accident conditions. The latter one can be further divided into so-called design basis accidents and design extension conditions. Design extension conditions include in the worst case conditions with core melting, called severe accidents. Instrumentation and equipment important for mitigating severe accident need to be tested to ensure the functionality during the severe accident environmental parameters and the mission time, which may be in the order of weeks or even years. The traditional environmental qualification method is not suitable in all cases for testing the severe accident instrumentation and dedicated mitigation equipment. Moreover, design extensions conditions and especially severe accidents are mostly not addressed in equipment qualification standards. This paper summarizes some aspects of the severe accident conditions testing.
