Simulation of Loss of Coolant Accidents at the Ontario Hydro Pickering NGS Simulator

Abstract

The purpose of the Pickering Simulator is the training of key nuclear power plant operating personnel. To fulfill this role, the models must be sophisticated enough to handle a wide variety of trainee interactions and instructor initiated malfunctions. However, because the programs must run in a real time operating environment, the models must avoid time consuming calculations. In spite of these two rigorous requirements, the models developed for use on the simulator give surprisingly good results when compared with more sophisticated models and actual plant experience. In particular , the simulation of loss of coolant accidents has not only resulted in valuable training, but it brought about changes in operating procedures and safety systems at the plant itself.
