Prediction of Decay Heat Power in Ontario Hydro CANDU Reactors During Prolonged Outages

Abstract

A standard model has been developed for readily estimating decay heat power as an input to analysis for planning of long duration reactor outages. The model is based on the format of the ANSI/ ANS-5.1 standard [1] which, by means of appropriate input data, has been tailored to predict decay heat power in OH reactors utilizing CANDU 37-element fuel.
