Letter from Mr. John S. Keenan to the U. S. Nuclear Regulatory Commission (Serial: BSEP 02-0169), "Request for License Amendments -
Core Flow Operating Range Expansion," dated November 12, 2002 Ladies and Gentlemen:
On November 12, 2002, Progress Energy Carolinas, Inc. requested a revision to the Technical Specifications (TSs) for the Brunswick Steam Electric Plant (BSEP), Units 1 and 2. The proposed license amendments revise TSs, as necessary, to support an expansion of the core flow operating range (i.e., Maximum Extended Load Line Limit Analysis Plus (MELLLA+)).
On May 20,2003, the NRC provided a verbal request for additional information (RAI) concerning the evaluation of the impact of MELLLA+ on the reactor pressure vessel. The response to this RAI is enclosed.
Please refer any questions regarding this submittal to Mr. Edward T. ONeil, Manager - Support Services, at (910) 457-3512.

Background
On November 12, 2002 (i.e., Serial: BSEP 02-0169), Progress Energy Carolinas, Inc.
requested a revision to the Technical Specifications (TSs) for the Brunswick Steam Electric Plant (BSEP), Units 1 and 2. The proposed license amendments revise TSs, as necessary, to support an expansion of the core flow operating range (i.e., Maximum Extended Load Line Limit Analysis Plus (MELLLA+)).
On May 20, 2003, the NRC provided a verbal request for additional information (RAI) concerning the evaluation of the impact of MELLLA+ on the reactor pressure vessel.
The response to this RAI follows.
NRC Question 21 Please provide an evaluation of the upper shelf energy (USE) and confirm that the USE and the reference temperature (ART) were established consistent with Regulatory Guide 1.99, Revision 2.
Response to NRC Question 2-1 Section 3.2.1 of GE Nuclear Energy Report NEDC-33063, "Safety Analysis Report for Brunswick Steam Electric Plant Units 1 and 2 Maximum Extended Load Line Limit Analysis Plus," dated November 2002 (i.e., M+SAR), states that the effect of the MELLLA+ operating range on fluence for the Brunswick Steam Electric Plant (BSEP) is negligible. However, a conservative 1% increase in fluence was assumed to demonstrate that the BSEP Pressure-Temperature curves are unaffected by Maximum Extended Load Line Limit Analysis Plus (MELLLA+). Further, an evaluation of the ART and USE was performed assuming the 1%increase in fluence. The evaluation was performed consistent with Regulatory Guide 1.99, Revision 2.
As discussed below, the impact on ART and USE is negligible. The ART increases by 0.4°F for the limiting material, and the USE Equivalent Margin Analysis (EMA) remains within the bounds defined by 10 CFR 50 Appendix G An evaluation was performed to determine the impact of MELLLA+ on the Reactor Pressure Vessel (RPV) Fracture Toughness for BSEP Units 1 and 2. The basis for the MELLLA+ evaluation was the Extended Power Uprate (EPU) evaluation.
Although MELLLA+ has no effect on the fluence used in EPU, as a conservative assumption, a 1% increase is evaluated for MELLLA+. Further, the ART and USE are evaluated using this conservatively increased fluence. The scope of evaluation for USE excluded the N16 nozzle; therefore, the limiting beltline plate and weld materials were evaluated. This evaluation was performed to the requirements of Regulatory Guide 1.99, Revision 2.
BSEP 03-0100 Enclosure Page 2 of 26 The calculation for USE uses the rounded 1/4T fluence obtained from the ART tables. It may also be noted that, while the 54 effective full power years (EFPY) percent decrease limit values were not approved by the NRC at the time the original evaluation was performed for BSEP, BWRVIP-74 has been approved at this time. Therefore, the 60-year life USE EMA comparison is based upon the currently approved limits.
Attached are the ART and USE tables for BSEP Units 1 and 2 for both 40- and 60-year life EFPYs including the 1% increase over the EPU fluence. For convenience, both EPU and MELLLA+ ART and USE EMA tables are provided. As can be seen by the results, the impact is negligible. The ART increases by 0.4°F for the limiting material, and the USE EMA remains within the bounds defined by 10 CFR 50 Appendix G
