- Chris Hawkins (NDE Level-Ill)
- Jhansi Kandasamy Tough Inspection Schedule & Difficult Inspection LR outage tasks were a small part of a large outage, and were not critical path
>>> we made no assessment of outage schedule or work control
" Outage schedule slippage pushed on-site inspection into a 2nd week
" Inspection follow-up to identified issues
- Bay 11 Coating Blisters
" Bay 3 Moisture Barrier Seal Problem
" Cavity Leakage and water intrusion into 4 bays Documentation Team Report 45 days after the Exit Meeting (mid Jan)
Inspection Results
- Satisfactorv Actions to evaluate primary containment structural integrity C

- Sampled 8 AMPs to Verify Commitment Implementation
- No Problems or Issues Identified, with Two Notable Exceptions
- Monitoring of Sand Bed Drain Lines
- Striorable Coatinq to prevent Water Intrusion e Perform Full Scope inspections of sand bed region every otner outage a Monitor drywell trenches every refueling outage
- Verified 2 commitment changes were done iaw Exelon commitment management program

Two Commitmentf 7 (b)(5)
SER Commitment 27, ASME Section XI, Subsection IWE, Item (2)
A strippable coating will be applied to the reactor cavity liner to prevent water intrusion into the gap between the drywell shield wall and the drywell shell during periods when the reactor cavity is flooded.
AmerGen was asked to provide the following information e Performance of the strippable coating during the two previous outages (2006 & 2004)
- Any condition reports (CRs), issue reports (IRs), or action requests (ARs) associated with the strippable coating from the 2006 outage SER Commitment 27, ASME Section XI, Subsection IWE, Item (3)
The sand bed region drains will be monitored daily during refueling outages.
- Sand bed drains were monitored by checking poly bottles, attached to the drain lines by tygon tubing. The drain lines could not be directly observed.
" After the cavity was drained, 2 of 5 tygon tubes were found disconnected, laying on the floor
" Sand Bed Bay 11 drain line poly bottle was empty during each daily check until Nov 15 (cavity was drained on Nov 12), when it was found full (> 4 gallons). Bay 11 was entered, visually inspected, and found dry. AmerGen believes that the 4+ gallons had been held up in the catch funnel (not directly observable). This implies that the Bay 11 drain line had not be draining into the poly bottle for some period of time.
