Serial: HNP-11-033 10 CFR 50.90 MAR 2 8 2011 U.S. Nuclear Regulatory Commission ATTENTION: Document Control Desk Washington, DC 20555 SHEARON HARRIS NUCLEAR POWER PLANT, UNIT NO. 1 DOCKET NO. 50-400/RENEWED LICENSE NO. NPF-63 WITHDRAWAL OF APPLICATION FOR REVISION TO TECHNICAL SPECIFICATION CORE OPERATING LIMITS REPORT (COLR) REFERENCES FOR REALISTIC LARGE BREAK LOCA (RLBLOCA) ANALYSIS Ladies and Gentlemen:
On March 23, 2010, Carolina Power & Light Company (CP&L) doing business as Progress Energy Carolinas, Inc. (PEC), submitted a License Amendment Request (LAR) to revise the Harris Nuclear Plant (HNP) Technical Specifications (TS) to add NRC-approved Topical Report (TR) EMF-2103(P)(A), Revision 0, "Realistic Large Break LOCA Methodology for Pressurized Water Reactors," to the COLR methodologies list. The addition of TR EMF-2103(P)(A),
Revision 0, approved by the NRC on April 9, 2003, would have allowed the use of the S-RELAP5 thermal-hydraulic analysis code methodology for Chapter 15 RLBLOCA in the HNP safety analyses.
Based on the complexity of the additional analyses needed to provide a complete response to the NRC's Request for Additional Information dated February 28, 2011 (ML110590620), CP&L has decided to withdraw the March 23, 2010, LAR adding TR EMF-2103(P)(A), Revision 0 to the HNP COLR methodologies list.
A new LAR will be submitted in 2011 upon completion of additional analyses.
In accordance with 10 CFR 50.91 (b), CP&L is providing the state of North Carolina with a copy of this letter.
This document contains no regulatory commitments.
Please refer any questions regarding this submittal to Mr. Dave Corlett, Supervisor -
