The nuclear industry has long relied upon bounding parametric analyses in predicting the safety margins of reactor designs undergoing design-basis accidents. These methods have been known to return highly-conservative results, limiting the operating conditions of the reactor. The Best-Estimate Plus Uncertainty (BEPU) method using a modernized version of the Code-Scaling,...
This study addresses the application of a full
reactor system computer code to simulate the reactor
primary and secondary loop thermal hydraulics, plant
control and protection systems during the steam generator
tube rupture (SGTR) events. The Trojan nuclear plant
which is owned and operated by the Portland General
Electric (PGE)...
