Title: Guide for reviewing estimates of production-cost increases that result from nuclear power plant outages
Abstract: Shutdowns of nuclear power plants typically result in significant increases in operating costs (production costs) for the affected utilities. This report presents a framework that will help users evaluate the reasonableness of estimated production-cost changes resulting from reactor shutdowns. The framework consists of three basic steps: (1) preliminary evaluation and classification of the outage, (2) evaluation of the input data and assumptions, and (3) evaluation of production-cost results. Several simplified procedures for estimating changes in production costs are presented.
