VERIFICATION OF CONTAINMENT INTEGRITY (61715)

!

The purposes of the inspection were to identify all containment penetrations and their associated isolating components and to verify that they were identified on P&lDs or other drawings; to determine which components have been

+

excluded from Type A, B,~ or C leak rate testing programs; and to verify that

'

the containment' penetrations and associated isolating components, excluded from U

the Type A, B, or C-leak rate testing programs, meet either the criteria for

,

waiver approval by the NRC Office of Nuclear Reactor Regulation (NRR)given test exemption, as set forth in Appendix J to 10 CFR Part 50 or have been

g

.

iThe inspectors performed a 100 percent walkdown, which involved 109 mechanica_1

- and 81 electrical containment penetrations, and 384 isolation valves associated

,

with these penetrations. This inspection.was performed inside and outside the

.

containment building, and, wherever possible, the inspectors traced associated system piping coming through an identified penetration back to its designated g

"

containment isolating component on either side of the containment building wall. The inspectors listed all of the penetrations and isolating components

. identified and compared this list with the associated controlled P&lDs

.;

identified in the Attachment.

It was noted during the containment walkdown

!

that'the 25 spare-~ penetrations were not labeled.- The inspectors also observed that six isolation valves-were without tags. The licensee took prompt

corrective action to correct the problem concerning the missing tags and

labels.

In addition to the missing valve tags,-the inspectors noted that

.. component tags subject to elevated temperatures were deformed with some being Ldifficult to read. The inspectors questioned-the licensee's choice of plastic-for permanent component tags. The remaining-penetrations and associated isolation valves were appropriately labeled and tagged.

The inspectors noted that the plant areas inspected were clean and free of trash indicating a well implemented and vigorous housekeeping effort. The

inspectors compared P&lDs with Procedures STS PE-017 and 18. The review did

not identify any discrepancies between the P&lDs and the proce@res. The

-

inspectors also noted that the P&lDs and the isometric drawings were being A

updated regularly.

.

.

The licensee stated that they do not have any exemptions from the Type A, B, or j

C tests.

-

'

No violations or deviations were identified in this program area.

3.

CONTAINMENT LOCAL LEAK RATE TESTING (61720)

The purpose of this inspection was to verify that primary containment local

. leak. rate tests (LLRT), as required by the Wolf Creek Generat;ng Station (WCGS)

!

Technical Specifications (TS), were performed to ensure that leakage through

,

testable containment penetrations and isolation valves would not exceed the allowable leakage specified. This review included records, procedures, and g

l independent calculations associated with the LLRT Type C tests.

F-5-During the inspection, the inspectors reviewed the primary containment LLRT procedure STS pE 017, Revision 7, dated September 28, 1988. The procedure was

complete and satisfactorily stated the ecceptance criteria for each penetration and the associated containnent isolation valve (CIV). Test procedure instructions were concise and previded for independent verification of test results and for system restoration. The inspectors reviewed records of LLRTs conducted during 1988.

In conducting this review, the inspectors verified that

.

corrective actions were taken on excessive leakage components and that I

appropriate retests were conducted on penetrations and CIVs. The cumulative data for containnent testable penetrations and CIVs were reviewed to verify that the containment local leak rate did not exceed the acceptance criteria.

Yhe LLRT test results were well within the acceptance criteria required by TS.

The inspectors' concluded that the licensee had a strong progrtm in the area of LLRT.

No violations or deviations were identified in the review of this prog'um area.

r

EXIT INTERVIEW

An exit meeting was held on April 27, 1990, with personnel identified in l

paragraph 1 of this report. At the crit interview, the inspectors summarized the scope and findings of the inspection. The licensee did not identify as proprietary any of the information provided to, or reviewed by, the inspectors.
