This repository includes generic PWR v1.2 model in various formats.
At present, the model considers various initiating events, including seismic activity, internal flooding, internal fires, hurricanes, high winds, ISLOCA (Interfacing Systems LOCA), upset conditions leading to transients, large break LOCA, loss of CCW (Component Cooling Water), loss of DC bus, loss of feedwater, loss of offsite power, large steam line breaks, medium break LOCA, steam generator tube ruptures, small LOCA, tornadoes, and excessive LOCA.
v1.2 of the model includes 56 event trees linked with 140 fault trees.
