Examination Summary (Cont'd) 1.1 ISI Examination Southwest Research Institute (SWRI) under the direction of the Salem ISI Group conducted one hundred (100) ultrasonic, fifty three (53) liquid penetrant, two (2) magnetic particle, and thirty eight (38) visual examinations on the Main Steam, Residual Heat Removal, Reactor Coolant, Chemical and Volume Control, Steam Generator Feedwater, Safety Injection, and Containment Spray Systems.

The following nonconf ormances were reported by SWRI: .

1.1.1 During the VT examination of valve 22-MS-13, a missing nut was discovered on the flange bolting below the valve (not in examination area) and reported to PSE&G on Customer Notification Form (CNF) SAM 2-2. The nut was installed and examined on Work Order No. 86-10-20-097-3.

1.1.2 Visual examination of 2-SJ-1218-5 flange bolting revealed heavy rust on the studs and nuts and was reported on CNF SAM 2-8.

The rust was remoyed on Work Order No.

86-10-30-001-3, and the nuts and studs were visually reexamined with no recordable indications noted and accepted by PSE&G personnel.

A UT examination of these nuts revealed no recordable indications. The VT indications were found to be acceptable in accordance with 1974 Section III, Paragraph NB-2582 and were accepted as is by PSE&G personnel.

1.1.4 Durin~ the PT examinations of 31-RC-1210-1, multiple linear indications were encountered. These indications were reported to PSE&G on CNF SAM 2-3. Approximately one-half of the indications were removed by buffing. Reexamination showed that the remaining indications were nonrelevant in accordance with PSE&G Procedure M9-IAP-5 and were accepted as is by PSE&G personnel.

The resulis of these tests revealed several Type "C" valves exceeding leak rate acceptance criteria, which were reworked to an acceptable condition, and one unique failure on an Electrical Penetration. Disassembly of Electrical Penetration #2-9 revealed a cracked bushing on the conax connector. The bushing was replaced and tested satisfactorily.

A total as found leakage rate of greater than .

225,157 SCCM was measured through all containment penetrations. Valve 2PR25 (check valve) was found leaking in excess of 200,000 SCCM. This valve was tested for the first time, due to the addition through our IST Program Revision.

We technically failed our as-found type "A" test (Ref. LER 86-012-00). After corrective maintenance, a total as left leakage rate of 66,392 SCCM was measured through all valves individually (type C tests) and Mechanical penetrations with resilent seals (type B tests).

Hydraulic snubber in-place functional testing was performed by WYLE Laboratories using the WYLE API Hydraulic Snubber Test System.

The results of these tests revealed the following:

One (1) 200 kip main steam isolation valve (MSIV) hydraulic snubber "as-found" test acceptable.

- All eight (8) 200 kip main steam isolation valve (MSIV) snubbers tested acceptable after being rebuilt.

- Six (6) 1000 kip steam generator (S/G) hydraulic snubbers "as-found" tests all acceptable.

- One (1) 1000 kip steam generator (S/G) snubber failed due to the bleed rate in tension exceed~ng the acceptance criteria. A spare snubber was installed.

The failed snubber was repaired and retested satisfactorily on site by WYLE Laboratories.

10. Examination Summary (Cont'd) 9.2 Summary - Mechanical Snubbers Technical Specification 4.7.9 requires functional testing on 10% of the total number of installed mechanical snubbers, during each Plant Refueling Outage. In addition, for each snubber that does not meet the acceptance criteria an additional 10% of the mechanical snubbers shall be functionally tested.

Wyle Laboratories was brought on site with their mobile snubber testing trailer to perform the tests. The first l10%) sample of mechanical snubbers consisted of : 2 PSA 1/4's, 1 PSA 1/2, 1 PSA 1, 5 PSA 3's and 3 PSA lO's for a total of 12 snubbers. In addition to the initial sample, all snubbers located in positions where failures occurred during the Unit II Second Refueling Outage were tested, consisting of: 6 PSA 1/4's, 1 PSA 1/2, and 2 PSA 3's.

There were two failures, both PSA-1/4's, one from the first sample and one from a position where a failure occurred during the Unit II Second Refueling Outage. Based on the two failures and the poor performeances of PSA 1/4's and PSA 1/2's in the past, it was decided that all PSA 1/4's and PSA 1/2's would be functionally Page 21 of 26

10. Examination Summary (Cont'd) tested. Twelve additional snubbers (11 PSA 1/4's and 1 PSA 1/2) were functionally tested with three failures (2 PSA 1/4's and 1 PSA 1/2).

Due to the failures in our first sample a second (10%) sample was tested consisting of: 2 PSA l's, 6 PSA 3's and 4 PSA lO's. As there were no failures in our second sample our mechanical snubber testing was complete.

Below is a summary of the functional testing of Unit 2's mechanical snubbers:

- Snubbers tested = 45

- Snubbers failed ~ 5 Model #'s of failures: PSA 1/4 = 4 PSA 1/2 = 1 PSA 1 = 0 PSA 3 = 0 PSA 10 = 0 Page 22 of 26

In addition, PSE&G Reasearch Corp. under the direction of the Salem ISI Group conducted the Waste Gas System Integrated Leak Rate test in accordance with ISI Procedure M9-ILP-WG-1.

There were no adverse findings in the examinations or tests conducted relative to this bulletin.

12.0 NRC Bulletin 82-02 "Degradation of Threaded Fasteners in the Reactor Coolant Pressure Boundary of Power Plants.

12.1 Summary Since only one primary steam generator manway was removed this outage, and the bolts were repla~ed with new ones, there were no surface examinations performed. However, all S/G primary manway bolts were visually examined in place. None were found to have been degraded or have any boron buildup.

  • All Reactor Coolant Pump Main flange bolting was visually examined in place. Moderate corrosion was noted. All flange bolts were hand wire brushed and reexamined with no apparent degradation.

All bolts were then lubricated with a thin coating of Felpro N5000 lubr~cant.
