Enclosure to SBK-L-17108 Supplement 56 - Revision to License Renewal ASME Section XI, Subsection IWL Program Operating Experience
U.S. Nuclear Regulatory Commission SBK-L-17108 / Enclosure I Page 2 The 3rd paragraph within the Operating Experience section of the Seabrook Station License Renewal Application, Appendix B - B.2.1.28 ASME Section XI, Subsection IWL, has been revised to reflect the latest 2016 ASME Section XI, IWL inspections as shown below.
The Seabrook Station ASME Section XI, Subsection IWL Program is implemented through the Seabrook Station Containment Surface Inspection Program. Some of the results of the inspection conclusions are based on the following reviews:
- 1. Containment inspections performed during Refueling Outage 8 (Spring of 2002) were completed satisfactorily with no indication of degradation of the concrete surfaces.
- 2. Containment inspections performed during Refueling Outage 10 (Spring of 2005) were completed satisfactorily with no indication of degradation of the concrete surfaces.
- 3. Containment inspections performed during Refueling Outage 12 (Spring of 2008) were completed satisfactorily with no indication of degradation of the concrete surfaces.
- 4. Containment ASME IWL inspections were completed on 1011112016. Seabrook Station Design Engineering evaluated the reported indications and determined that none of the indications have an adverse impact on the structural integrity or structural performance of the Containment structure. No ASME Code Repair activities were required as a result of this ASME IWL examination.
