Seismic margin analysis of CANDU primary heat transport system
The Pickering Nuclear Generating Station A was designed in the late 1960s. Since that time, estimates of seismic hazard in eastern North America have changed. Ontario Hydro is currently performing a seismic margin assessment of the station. The reactor system is a heavy water CANDU system. A screening walkdown identified the primary heat transport system for analysis since it is much different from light water reactor primary coolant systems assessed in previous seismic margin assessments and seismic probabilistic risk assessments. The high confidence of low probability of failure (HCLPF) of the system was computed deterministically in terms of a uniform hazard spectrum for the Pickering site. This paper describes the modelling, analysis and seismic margin assessment of the system.
