Pilgrim Nuclear Power Station Docket 50-293 License No. DPR-35 Response to NRC Request for Additional Information Appendix K Measurement Uncertainty Recovery - Power Uprate Request LETTER NUMBER:
2.03.016
Dear Sir or Madam:
The NRC and Entergy conducted a teleconference on January 31, 2003, to discuss NRC questions related to the Entergy Power Uprate Request. Attachment 1 of this letter provides the requested information.
This response to the request for additional information does not change the no significant hazard conclusions previously submitted in Entergy Letter 2.02.048, dated July 5, 2002.
Should you have any questions or comments concerning this submittal, please contact Bryan Ford at (508) 830-8403.
I declare under penalty of perjury that the foregoing is true and correct. Executed on the 10th day of February 2003.
Sincerely, Charles M. Dugger, JRH/dd 203016

ArnACHMENT 1 LETTER NUMBER 2.03.016 Response to NRC Request for Additional Information Appendix K Measurement Uncertainty Recovery-Power Uprate Request 203016
Response to NRC Request for Additional Information Appendix K Measurement Uncertainty Recovery-Power Uprate Request The current main steam line break, DBA-LOCA, and containment analyses were performed at 102% of CLTP (Current Licensed Thermal Power). Therefore, the equipment qualification envelope inside containment continues to be applicable for the TPO (Thermal Power Optimization) conditions. The normal radiation profiles both inside and outside containment and the accident temperature, pressure, and humidity environments outside containment were based on the CLTP. The changes resulting from TPO are small and in general bounded by the current qualification envelopes. Outliers are being resolved by reanalysis, refined radiation calculations (location-specific), or by slightly reduced qualified life. Consistent with commitment C2 in Entergy Letter 2.02.048, these outliers will be resolved prior to operating above the current licensed thermal power.
