-2-Results: Within the area inspected, no violations or deviations were integrated leak rate testing (CILRT) g program in the area of containment identified. The licensee had a stronandlocalleakratetesting(LLRT). A 100 percent visual inspection of accessible containment penetrations was performed by the inspectors inside and outside the containment building. The inspectors did not observe any significtnt discrepancies. The inspectors did
. note that four penetrations were not labeled and nine valves did not have identification tags. The licensee took prompt corrective actions to label the penetrations and replace the missing tags. The plant locations inspected were clean and free of trash indicating that, although the plant was in a refueling outage, the licensee had a well implemented and vigorous housekeeping effort, inspection Conducted May 7-11. 1990 (Report 50-499/90-15)

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, excluded from the Type A, B, or C leak rate testing programs, met either the criteria for exemption, as set forth in Appendix J to 10 CFR Part 50 or have been given
-
-
test waiver approval by the NRC Office of Nuclear Reactor Regulation (NRR).
'A The inspectors performed a 100 percent walkdown of the accessible areas, which involved 95 mechanical and 69 electrical containment penetrations, and 395 isolation valves associated with these penetrations. The inspectors were-not able to walkdown four inaccessible penetratiot.s and their six associated valves because these components were located in to a high contamination area in the fuel handling building. 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 containment isolation valve on either side of the containment building wall. ~The inspectors listed all of the penetrations and isolation valves identified in the Attachment.
It was noted during the containment
.
walkdown that four penetrations were not labeled. The inspectors also observed

'
identification tags. The licensee took prompt action to correct the problem
,
L concerning missing tags and labels. The remaining penetrations and associated isolation valves were appropriately labeled and tagged.
F The inspectors noted that the plant locations inspected were clean and free of trash indicating a well implemented and vigorous housekeeping effort. The inspectors compared PalDs with all 0 PSP 11 procedures. The review did not identify any discrepancies between the P& ids and the procedures. The inspectors also noted that the licensee had established a program to update the PalDs regularly.
-The licensee stated that they did not have any exemptions from Type A, B, or C tests.
No violations or deviations were identified in this program area.

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 Technical Specifications (TS), were performed to ensure that leakage through testable containment penetrations and isolation valves did not exceed the allowable leakage specified. This review included records, procedures, and independent calculations associated with the-LLRT Type C tests. During the inspection, the inspectors reviewed the primary
,
containment LLRT Procedures OPGP03-ZE-0011, Revision 3, dated August 1,1989, and OPSP11-ZA-0005, Revision 4, dated April 6, 1990. The procedures were-g complete and satisfactorily stated the acceptance criteria for each penetration andtheassociatedcontainmentisolationvalve(CIV). Test procedure instruc-tions were concise and provided for independent verification of test results for system restoration. The inspectors reviewed records of LLRTs conducted during 1989-1990.
In conducting this review, the inspectors verified that corrective actions were taken on excessive leakage components and that appropri-ate retests were conducted on penetrations and CIVs. The cumulative data for r
containment testable penetrations and CIVs were reviewed to verify that the containment local leak rate did not exceed the acceptance criteria. The LLRT test results were well within the acceptance criteria required by TS.
The inspectors also reviewed the training program for the individuals who perform the LLRTs. The review indicated that the licensee had a very strong program in the area of treining for LLRTs.
-
No violations or deviations were identified in the review of this program area.
4.
EXIT tlEETING An exit meeting was held on May 11, 1990, with personnel identified in paragraph 1 of this report. At the exit meeting, the inspectors summarized l
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.
