Commercial Reactor Criticality Depletion For Grand Gulf, Unit 1

The objectie of this calculation is to document the Grand Gulf, Unit 1, (GG1) fuel depletion calculations. The GG1 reactor is a boiling water reactor (BWR) owned and operated by Entergy Operations Inc. The Commercial Reactor Criticality (CRC) evaluations support the development and validation of the neutronic models used for criticality analyses involving commercial spent nuclear fuel in a geologic repository. This calculation is performed as part of the evaluation CRC program. This report is an engineering calculation supporting the burnup credit methodology of YMP 2000 (Ref. 6.5) and was performed under Framatome ANP Administrative Procedure 0402-01, Preparing and Processing FANP Calculations (Ref. 6.4) and Framatome Quality Management Manual (Ref. 6.11). This calculation is subject to the Quality Assurance Requirements and Description (Ref. 6.6). This calculation used SCALE code system to perform the fuel depletion calculations.
