The purpose of this letter is to revise the completion date of two of the commitments provided in Reference 3. Reference 3 provided a detailed description of the actions PPL Susquehanna, LLC (PPL) is committed to take to resolve the concerns identified in Generic Letter (GL) 2003-01 "Control Room Habitability (CRH)." The Attachment to this letter is an updated version of Attachment 2 from that submittal. The Attachment to this letter updates the status of three commitments which have been completed, and reflects the revised completion dates of two commitments.
Subsequent to development of the commitments delineated in Reference 3, PPL initiated plans for an Extended Power Uprate (EPU). To fully resolve the issues identified in the GL and to implement the EPU, conversion to the Alternate Source Term (AST) is required. Efficient use of both PPL and NRC resources in the development and review of the requisite AST analyses and AST license amendment request would be best served by a combined CRH and EPU license amendment request.
Document Control Desk PLA-5861 Thus, PPL is revising the completion date of the following two commitments:
"PPL commits to providing a dose consequence submittal to the NRC, using the methodology described in Regulatory Guide 1.183, Alternative Radiological Source Terms For Evaluating Design Basis Accidents at Nuclear Power Reactors."
and "PPL will perform an assessment of the AP Technical Specification and determine if changes to the Technical specification are required."
Both commitments will be completed by December 30, 2005 rather than June 30, 2005.
These changes will allow sufficient time for completion of one comprehensive AST analysis and AST license amendment request. The alternative to these commitment changes would be to make two AST submittals, one for the CRH GL and one forEPU, within less than six months of each other. This combined submittal constitutes more efficient use of both PPL and NRC resources.
Additionally, the revised commitment completion dates are believed acceptable based on the unfiltered in-leakage flow rates measured during tracer gas testing performed December 2005 that are bounded by preliminary dose consequence analyses previously performed that concluded high unfiltered in-leakage flow rates could be accommodated.
The contents of this letter have been discussed with Mr. Richard Guzman, the SSES NRR Project Manager.
Any questions regarding this information should be directed to Mr. Michael H. Crowthers at (610) 774-7766.
