Validation of the MELCOR input model for a CANDU PHWR containment analysis by benchmarking against integrated leakage rate tests

Full scope simulation of VVER-1000 blowdown source and containment pressurization in a LBLOCA by parallel coupling of TRACE and CONTAIN

“…Meanwhile, the effects of engineering safety features (ESFs) such as spray system were considered in their evaluation. Kim et al (2018) have used MELCOR to simulate containment pressurization in a CANDU PHWR containment. They have validated their results against integrated leakage rate test that is a domestic regulatory requirement by nuclear safety and security commission of South Korea.…”
