Request for Additional Information B.1.10-5 Containment Inservice Inspection Program

=

Background===

The Generic Aging Lessons Learned Report states that proper maintenance of protective

coatings inside cont ainment is essential to ensure operability of post-accident safety systems that rely on water recycled through the containment sump or drain system. Degradation of coatings can lead to clogging of strainers, which reduces flow through the sump or drain system.

Issue:

The Cooper Nuclear Station (CNS) license renewal application (LRA) does not credit the protective coating monitoring and maintenance program for aging management; the containment Inservice Inspection (ISI) Program manages the effects of aging on the drywell shell. Although

the licensee stated that enhancements will be made to the cont ainment ISI Progr am to inspect surfaces for signs of distress, there needs to be adequate assurance that there is proper maintenance of the protective coatings in containment, such that they will not degrade and become a debris source that may challenge the emergency core cooling system's performance.

Request 1. On page B-10 of the LRA (Agencywide Documents Access Management System Accession No. ML083030227), line item XI.S8 states that the NUREG-1801 program is not credited for aging management. The containment ISI Program manages the effect of aging on the drywell shell. Please discuss how the containment ISI Program meets the recommendations of NUREG-1801 X1.S8 in managing the effects of aging at CNS.

2. Please describe, in detail, the CNS service level 1 coatings program.

a. Please describe how the program will ensur e that there will be proper maintenance of the protective coatings insi de the containment, such that they will not become a debris source that could impact the operability of post-accident safety systems that rely on water recycled through the containment sump or drain system in the extended period of operation. b. Please describe the frequency and scope of the inspections, acceptance criteria, and the qualification of personnel who perform containment coatings inspections.
