The objective of this calculation is to establish an isotopic database to represent commercial spent nuclear fuel (CSNF) from boiling water reactors (BWRs) in criticality analyses performed for the proposed Monitored Geologic Repository at Yucca Mountain, Nevada. Confirmation of the conservatism with respect to criticality in the isotopic concentration values represented by this isotopic database is performed as described in Section 3.5.3.1.2 of the Disposal Criticality Analysis Methodology Topical Report (Reference 7.1). The isotopic database consists of the set of 14 actinides and 15 fission products presented in Section 3.5.2.1.1 of Reference 7.1 for use in CSNF bumup credit. This set of 29 isotopes is referred to as the principal isotopes and are provided in Table I of this document. The oxygen isotope from the U02 fuel is also included in the database but is not included in the 29 principal isotopes.
