This paper describes a depletion code validation approach for criticality safety analysis using burnup credit for actinide and fission product nuclides in spent nuclear fuel (SNF) compositions.

WPNCS Expert Group on Burn-up Credit Criticality Safety (BUC) Burn-up credit is a safety approach that accounts for the reduction in reactivity of configurations with spent nuclear fuel due to the change in their composition after irradiation. @article{osti_, title = {OECD/NEA burnup credit calculational criticality benchmark Phase I-B results}, author = {DeHart, M D and Parks, C V and Brady, M C}, abstractNote = {In most countries, criticality analysis of LWR fuel stored in racks and casks has assumed that the fuel is fresh with the maximum allowable initial enrichment.. This assumption has led to the design of widely spaced.   An Approach for Validating Actinide and Fission Product Burnup Credit Criticality Safety Analyses - Isotopic Composition Predictions Article (PDF Available) in Nuclear technology (2) By taking credit for the effects of irradiation (or burn-up) of the fuel it may be possible to demonstrate criticality safety with less restrictive criticality controls without reducing safety. This report presents an understanding of issues and the state-of-the-art in burn-up credit (BUC) applications in .

It is also intended to foster the exchange of international experience in licensing and implementation of burnup credit (BUC) applications. In the last 20 years, burnup credit (BUC) was more frequently applied in criticality safety analysis of spent nuclear fuel systems instead of the "fresh fuel assumption” usually made in the past. The goal of any criticality safety analysis based on burnup credit will be to demonstrate that an adequate margin of subcriticality is provided while taking credit for the reduced reactivity of spent fuel. In practice, determination of subcriticality using a burnup credit approach requires aCited by: 5.
