This letter requests the withdrawal of Nuclear Regulatory Commission (NRC) review and approval of a previously submitted license amendment request dated January 30, 2003 (Letter PY-CEI/NRR-2665L). The license amendment request involved a proposed modification to the existing Minimum Critical Power Ratio (MCPR) Safety Limit contained in Technical Specification 2.1.1.2. Specifically, the change modified the MCPR Safety Limit values, as calculated by Global Nuclear Fuel (GNF), by decreasing the limits for both the two recirculation loop and the single recirculation loop operation.

The change resulted from the core reload analysis performed for the PNPP Fuel Cycle 10.

As a component of the reload licensing methodology used by the Perry Nuclear Power Plant (PNPP), ["General Electric Standard Application for Reactor Fuel" (GESTAR II)], the as-loaded core is required to be compared to the reference core. The need for this evaluation is due to the assumptions made as to the core end state which are used in the development of the reference core. This ensures that the calculations performed to develop the reference core are applicable to the as-loaded core. This evaluation has been completed. As a result, the values associated with the MCPR Safety Limits have changed from those values proposed in the aforementioned license amendment request. Since the current PNPP MCPR Safety Limits are more conservative than the proposed revised values, initial Fuel Cycle 10 operation will be based upon the current Technical Specification MCPR Safety Limit values. Therefore, the proposed license amendment is not needed at this time.
