Report No. 1009325, Revision 2, August 2007, 'Risk Impact Assessment of Extended Integrated Leak Rate Testing Intervals' JAC No. MC9663)," dated June 25, 2008 The LSCS LAR (Reference 1) included a statement in Section 3.4.3 of Attachment 1 relative to the LSCS Third Interval Containment Inservice Inspection (CISI) Program Plan that was under development at the time of submittal of the LAR (i.e., October 26, 2016). The Third Interval CISI Interval is effective as of October 1, 2017, through September 30, 2027 for LSCS, Units 1 and 2.
In response to discussions with the NRC, EGC has evaluated the Safety Evaluation (SE) for NEI TR 94-01, Revision 2 (Reference 2), Limitations and Conditions 2 and SE Section 3.1.1.3.
Limitations and Conditions 2 for NEI TR 94-01, Revision 2, states the following:
The NRC staff finds that the use of NEI TR 94-01, Revision 2, is acceptable for referencing by licensees proposing to amend their TSs to permanently extend the ILRT surveillance interval to 15 years, provided the following conditions are satisfied:
- 2. The licensee submits a schedule of containment inspections to be performed prior to and between Type A tests. (Refer to SE Section 3.1.1.3).
Included in Tables 1 and 2 are the LSCS Third Interval CISI schedules, which were not originally provided in Reference 1. The schedule information provided in these tables demonstrates LaSalle's compliance with Limitations and Conditions 2 for NEI TR 94-01, Revision 2 (Reference 2).
