Due to global warming, the amount of snowfall in abnormal snowfall events may increase in the future. In order to evaluate the effect of global warming on the probability of exceeding the limit temperature at the core outlet as a core damage factor in a sodium-cooled fast reactor, a hazard curve of snowfall was developed considering global warming, and a dynamic PRA was performed. As a result, it was found that the amount of snowfall in abnormal snowfall events increases due to global warming, and the probability of exceeding the limit temperature increases.

In development of a quantitative risk assessment method to the external hazards for a sodium-cooled fast reactor, a dynamic PRA using the Continuous Markov chain Monte Carlo (CMMC) method was performed to evaluate the effect of global warming on the probability of exceeding the temperature limit as a core damage factor. There is a possibility that the amount of snowfall in abnormal snowfall events will increase due to global warming in the future. A hazard curve of snowfall considering global warming was developed. The results show that the probability of exceeding the temperature limit is increased by the abnormal snowfall events due to global warming.

A dynamic PRA using the Continuous Markov chain Monte Carlo (CMMC) method was performed for a sodium-cooled fast reactor to evaluate abnormal snowfall events in which the snowfall amount tends to increase due to global warming. In the analysis, the probability of exceeding the core outlet temperature limit after 24 hours was evaluated. The loss of functions of the emergency diesel generator and the air cooler due to snowfall and the recovery of the functions by the operator's snow removal as an accident management measure were considered. The results show that snow removal as an accident management measure is not effective under abnormal snowfall conditions with considering global warming.
