In Reference 1, Nuclear Management Company, LLC (NMC), provided the 60-day response to Generic Letter (GL) 2003-01 for PBNP. The letter included responses to ltems I(b), 2 and 3 of that letter and commitments to provide schedules for responses to ltems I(a) and 1(c). The basis for the commitments was the need to conduct a control room envelope (CRE) baseline integrated unfiltered in-leakage test.

Reference 2 provided the preliminary results for unfiltered in-leakage into the CRE as less than 100 scfm while the control room ventilation system is operating in the emergency mode assumed in the radiological accident analysis. Schedules for providing the final CRE unfiltered in-leakage results and responses to ltems 1(a) and 1(c) were also provided as new commitments. Reference 3 revised the commitment dates provided in Reference 2. The final measured control room envelope unfiltered in-leakage value was provided to the NRC in Reference 4.

Document Control Desk Page 2 On October 24,2006, a teleconference was held between NRC and NMC representative to discuss previous NMC responses to GL 2003-01. During this discussion, NMC agreed to submit a supplemental response to the NRC providing additional information regarding GL 2003-01 Questions 1 and I(a). Reference 5 supplemented the response to Questions 1 and I(a) and provided the following commitment:

"NMC will submit a license amendment request to the NRC revising the current accident analysis for PBNP to demonstrate compliance with the dose limits of 10 CFR 50, Appendix A, GDC-19, using the Alternative Source Term by July 30, 2007. As part of this submittal, the post-accident reliance on KI for control room staff will be addressed."

In Reference 6, the NRC closed GL 2003-01 referencing NMC's commitments to submit license amendment requests to revise the current accident analysis for PBNP using the AST methodology and to reference an acceptable surveillance methodology based on TSTF-448, following NRC approval.

Summarv of Commitments The following revises the commitment date as stated in Reference 3. The proposed commitment change was discussed with the PBNP NRC Project Manager on March 28,2007:

"NMC will provide Technical Specification changes to reference an acceptable surveillance methodology (and plans for any associated plant modifications to the CRE) to support requested information in GL 2003-01, Item (c), for PBNP no later than 180 days following NRC approval of TSTF-448."
