License Amendment Request for Adoption of TSTF-478-A, Revision 2 Supplemental Response to Revise Technical Specifications Page Mark-ups
References:
- 1) Letter from Pamela B. Cowan, Exelon Generation Company, LLC, to U.S.
Nuclear Regulatory Commission - License Amendment Request for Adoption of TSTF-478-A, Revision 2, "BWR Technical Specification Changes that Implement the Revised Rule for Combustible Gas Control," Using the Consolidated Line Item Improvement Process, dated July 30, 2009
- 2) Federal Register Notice 72FR65610 - Notice of Availability on Model Safety Evaluation; Model No Significant Hazards Determination, and Model Application for Licensees that Wish to Adopt TSTF-478, Revision 2, "BWR Technical Specification Changes that Implement the Revised Rule for Combustible Gas Control," dated November 21, 2007 By letter dated July 30, 2009 (Reference 1), Exelon Generation Company, LLC (Exelon) submitted a License Amendment Request (LAR) to revise the Technical Specifications (TS) for Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3. The proposed changes would revise the TS for PBAPS, Units 2 and 3, consistent with NRC-approved Industry TS Task Force (TSTF) Change Traveler TSTF-478-A, Revision 2, "BWR TechnicalSpecification Changes that Implement the Revised Rule for Combustible Gas Control"(Reference 2). The proposed changes would delete the TS requirements associated with the "Containment Atmospheric Dilution (CAD) System."
Subsequently, it was identified that the mark-ups on TS page 3.8-41 for Units 2 and 3 contained an editorial discrepancy. Specifically, there was a strikeout line through the reference to "LCO 3.6.3.1" indicating that the section should be deleted. However, the strikeout line was not completely carried through to include the remaining portion of the reference, i.e., "Containment Atmospheric Dilution (CAD) System."
Accordingly, this letter is being submitted to correct this editorial discrepancy. Attachment 1 contains the revised mark-up for the affected TS page for Units 2 and 3 and Attachment 2 includes the revised re-typed page for the affected Units 2 and 3 TS page.
