[1K01] Analysis of Pressure Suppression Chamber Behavior in BWR Accidents by GOTHIC Code

*Hideo Konishi1, Hiroshi Eguchi1, Masashi Sekine1 (1. Regulatory Standard and Research Department, Secretariat of Nuclear Regulation Authority (S/NRA/R))

Keywords:BWR pressure suppression chamber, accident behavior analysis, GOTHIC, temperature stratification

The GOTHIC code was used to analyze the behavior of the BWR pressure suppression chamber when the containment vessel vent occurred at the time of the accident, and the influence on the temperature stratification in the pool water was examined.
