Clarification - Non-Conservative TS 5.5.13 - Containment Peak Pressure and UHS LARs Gentlemen, Two clarifications.
During LaSalles public meeting on April 4, 2012, LaSalle cited use of AL 98-10 administrative controls for a non-conservative TS 5.5.13 (Pa) which was identified mid-2011. Imposing administrative controls in response to an improper or inadequate TS (AL 98-10) is considered an acceptable short-term corrective action. EGC proposed that the Containment Accident Peak Pressure analysis (TS 5.5.13) should come in under a separate licensee amendment request (LAR) submittal to facilitate timely review. Following staff discussions from an acceptance prospective only, the staff is in general agreement that there is no LIC-109 linked review concern predicated on EGCs ability to develop and submit a correction to Technical Specification 5.5.13 (which bounds EPU conditions) well in advance of submittal of your EPU application. I request your expected submittal date for this application to ensure internal alignment for concurrence of the public meeting summary.
Regarding LaSalles future ultimate heat sink (UHS) LAR, no regulatory decision has been made on the submittal content, LIC-109 acceptability, or its future review timeline. I encourage that UHS for EPU be considered a future pre-application topic for discussion with the staff.

DiFrancesco request I talked with Nick, he stated that they had settled on two separate and most likely unlinked submittals on UHS (site and EPU). However, they would not be able to make a decision on the submittals are unlinked until they see the site submittal. I provided verbal assurance that the EPU plan was to not change technical specification and that we would be bounding the site submittal and not dependent on it. He did have a concern on the burden on the NRC staff with both LaSalle and PB EPU submittals and the site UHS submittal. He needed a date for the site UHS submittal to ensure staff planning. I explained that we did not have a current hard date schedule. I also informed him that I am invited to the site planning meetings and can keep him informed if a date is determined. I also mentioned that they are planning to include the UHS submittal as part of the site bi-weekly call with him.
