Pursuant to 10 CFR 50.46(a)(3), Northern States Power Company - a Minnesota corporation (NSPM), is providing the annual report of changes or errors identified in the Emergency Core Cooling System evaluation models or their application for the Monticello Nuclear Generating Plant (MNGP). This report is for the period between July 2007 and July 2008.
The MNGP Loss of Coolant Accident (LOCA) analyses of record are contained in General Electric (GE) reports submitted for the MNGP re-rate (Reference I ) and the LOCA analysis for the GE14 fuel type (Reference 2). One GE fuel type has been in use over this time period, the GE14 fuel type. The current operating cycle (MNGP Cycle 24) core loading consists of only the GE14 fuel design type.
During the period covered, no notification of a change or error resulting in a change to the calculated Peak Clad Temperature (PCT) was received from GE for the fuel design type. Therefore, the licensing basis PCT and the PCT Summary provided in Table Iof the enclosure is unchanged from the last annual report (Reference 3) except that the GEI 1 fuel design has been removed from the table, since it is no longer resident in the core.
