S083012 シビアアクシデント時のBWR原子炉建屋水素ベンド対策に関する検討 : その1 ; CFD による水素詳細挙動の三次元解析
詳細
Installation of the hydrogen vent equipment will be required for existing nuclear plants against severe accident. It is necessary to construct the analytical method to evaluate the performance of the hydrogen vent function. In this research, CFD was examined as an evaluation method of the hydrogen concentration in the reactor building. The condition that the gas of the hydrogen concentration 34% enters in the operation floor was assumed. It was confirmed that the temperature of the operation floor became uniform and the hydrogen concentration became less than 4% as a result of the analysis.
