LASALLE COUNTY STATION, UNITS 1 AND 2 - CORRECTION TO ISSUANCE OF AMENDMENTS (TAC NOS. MB9004 AND MB9005)

Dear Mr. Skolds:

On November 13, 2003, the Nuclear Regulatory Commission (Commission) issued Amendment No. 163 to Facility Operating License No. NPF-11 and Amendment No. 148 to Facility Operating License No. NPF-18 for the LaSalle County Station, Units 1 and 2, (LaSalle) respectively. The amendments decreased the frequency associated with Technical Specification (TS) Surveillance Requirement (SR) 3.7.7.1 for Turbine Bypass Valve (BPV) testing from 7 to 31 days. Amendment No. 148 for Unit 2 should have been issued as Amendment No. 149.

The Commission is reissuing Amendment No. 148 as No. 149. Enclosed is a corrected copy of TS page 3.7.7.1 for Amendment Nos. 163 and 149, and a revised first page of the Safety Evaluation issued on November 13, 2003.

We apologize for any inconvenience this may have caused.

Sincerely,

1.0 INTRODUCTION

By application dated May 19, 2003, Exelon Generation Company (EGC, the licensee) requested changes to the Technical Specifications (TS) for the LaSalle County Station, Units 1 and 2. The proposed changes would revise Appendix A, Technical Specifications (TS), of Facility Operating License Nos. NPF-11 and NPF-18, respectively. Specifically, the proposed change will decrease the frequency associated with TS Surveillance Requirement (SR) 3.7.7.1 for Turbine Bypass Valve (BPV) testing from 7 to 31 days. The proposed change is consistent with the testing frequency contained in NUREG-1434, "Standard Technical Specifications General Electric Plants, BWR/6," Revision 2, dated June 2001, for BPV testing.

The 7-day frequency associated with SR 3.7.7.1 was established in the LaSalle County Station (LSCS) TS during conversion to improved Standard Technical Specifications (STS) format due to the testing frequency contained in the LSCS custom TS and the difficulties experienced with other Electro-Hydraulic Control (EHC) system valves to consistently pass their surveillance tests. LSCS has recently re-evaluated the performance of these valves and has determined that the current performance of these valves supports decreasing the testing frequency of the BPVs from 7 to 31 days.

2.0 REGULATORY EVALUATION

The staff finds that the licensee in Section 4.0 of Attachment 2 to its submittal identified the applicable regulatory requirements. The regulatory requirements for which the staff based its acceptance are described below.

The staff reviewed the proposed changes for compliance with Section 50.36 of Title 10 of the Code of Federal Regulations (10 CFR), and agreement with the precedent as established in NUREG-1434. In general, licensees cannot justify technical specification changes solely on the basis of adopting the model Standard Technical Specifications (STS). To ensure this, the staff makes a determination that proposed changes maintain adequate safety. Changes that result in relaxation (less restrictive condition) of current TS requirements require detailed justification.

In general, there are two classes of changes to technical specifications: (1) changes needed to reflect contents of the design basis (TS that are derived from the design basis), and (2) voluntary changes to take advantage of the evolution in policy and guidance as to the required content and preferred format of technical specifications over time.
