Abstract

Analysis of source terms in nuclear spent fuel applications is discussed, including decay heat, activity, and criticality safety using burnup credit. The analysis is based on depletion and decay capabilities in the SCALE nuclear analysis code system. The underlying codes, nuclear data, computational methodologies and uncertainties in calculated source terms are addressed, with examples presented for different spent fuel types.
