Graph of Decay heat as fraction of full power from a SCRAMed operating power reactor.  Two models are displayed in the graph, one being Retran, which uses a 11 group exponential decay, the other being Todreas and Kazimi from published work in 1990, which was adapted from previous empirical correlations.  The Retran model inputs no assumptions of operating history, and the Todreas model requires the operating time before shutdown, which was assumed to be 2 years for this application.
