Keywords:uncertainty, internal flooding

The evaluation of the time progress for the internal flooding scenario considering the uncertainty of the start-up time of the equipment is important for taking countermeasures against the accident since the internal flooding scenario depends on the uncertainty. Therefore, the uncertainty of the start-up time was introduced to the time progress of the internal flooding scenario and the effect on core damage probability was investigated.
