Response of a DSNP pressurizer model under accident conditions

D. Saphier, John M. Kallfelz, Lotfi A. Belblidia

Abstract

Recently a new pressurizer model was developed for the DSNP simulation language. The model was connected to a simulation of the Trojan pressurized water reactor (PWR) and tested by simulating a loss-of-off-site power (LOSP) anticipated transient without scram. The results compare well to a similar study performed using the RELAP code. The pressurizer model and its response to the LOSP accident are presented.
