Inservice Inspection - Review of Program (73051) Program Approval In a letter dated July 5, 1983 from K. P. Baskin (SCE) to Miraglia (NRC), the licensee submitted the first 10 year Inservice Inspection (ISI) program for San Onofre Unit There has been additional correspondence and meetings between the licensee and NRC on the Unit 3 ISI progra At the date of this inspection, NRC had not yet completed its review and issued a Safety Evaluation Report (SER) on this progra . Program Organization The Unit 3 ISI program is based on the requirements of the ASME code,Section XI, 1977 edition, through the 1979 summer addend The ISI program examination area summary sheets from manual M38219, list the areas to be examined, the method and extent of the examination, calibration blocks required and other useful information. The ISI program is established by Operations and Maintenance (0&M) support order 50123-IN-1, "Inservice Inspection Program, Revision 1 of July 30, 1987. The ISI program is implemented by O&M support procedure 50123-XVII-1, "Inservice Inspection Program Implementation", Revision 3 of November 21, 198 ,Je

.

J The ISI program is updated and revised by the licensee, per O&M y support procedure 50123-XVII-1.1, "Inservice Inspection Program Maintenance", Revision 1 of January 26, 198 '

~

The licensee's repair and replacement program is addi nsed in 0&M support procedure 50123-XVII-3,:"ASME Section XI Repair and Replacement Program Administration", Revision 0, TCN No. 0-4 of April 27, 1988. This procedure meets the requirements of the ASME code, section XI, for both a repair program (as specified in article IWA-4000) and a replacement program (as specified in article

.IWA-7000), Quality Assurance Program Topical Report SCE-1A, Quality Assurance Program, Amendment 10 dated July 1987, addressed QA involvement in the ISI program. Discussions with the QA audit group and the surveillance group, identified that there had been no recent audits or surveillances performed in the ISI are Around the first of 1988, the licensee created a special projects group in the surveillance group. This group elected to minimize the surveillances of ISI activities, since there was no history of major problems in this area at the licensee facility, or other facilities checke No violations or deviations were identified in the areas reviewe . Inservice Inspection - Review of Procedures (73052)

A sample of the latest revisions of applicable ISI procedures, issued since the last ISI review, were reviewed by the inspector to assure compliance with the ISI program. All procedures specified qualification and certification of NDE personnel, where applicable. The methods of recording, evaluating, and dispositioning findings and reporting requirements were addressed in the applicable procedures in accordance with the applicable code requirements. The technical content, such as, method of examination, extent, and technique, were adequately described in conformance with the requirements and guidance of the ASME Code, Section No violations or deviations were identified in the areas reviewe . Inservice Inspection - Observation of Work and Work Activities (73753)

This was the licensee's cycle 4, third refueling outage, and the second ISI period of the first ten year ISI interval. The contractor ISI examiners were provided by combustion engineerin The inspector reviewed the qualifications and certification records for the ISI examiners. The inspector observed available ultrasonic (UT),

liquid penetrant (PT) and visual (VT) examinations performed on steam generator no. 2 continuous blowdown piping and associated support i

The inspector reviewed all-the available NDE ISI data sheets generated ,

prior to and during this. inspectio l No violations or deviations were identified in the areas reviewe . Followup of Previously Identified Items (92701 and 92703) (Closed) Open Item (50-362/87-03-01) ISI Procedure Changes to Ensure Timely Responses for ISI Items Found on an Operating Unit (Unit 3)

During a previous inspection, the inspector found that contractor ISI Visual (UT) examinations had identified potentially missing support items on an operating unit. The unit operated for an additional three weeks, prior to shutdown for a refueling outage, without receiving any operability assessments of the ISI examination results. The inspector concluded that the existing licensee ISI procedures did not incorporate the same timely Quality Assurance / licensee responses in all cases, for potential or actual nonconforming, rejected or missing items found during ISI examinations, that other non-ISI licensee procedures di The licensee issued Temporary Change Notice (TCN) No. 1-2 to 0&M support procedure 50123-XVII-1,0, "Inservice Inspection Program Implementation", Revision 1 on March 4, 1987, to correct the identified weakness. This item is closed, (Closed) Open Item (50-362/87-03-02) ISI Personnel Understanding of Drawing Updates During a previous inspection, the inspector identified that it appeared that both licensee and contractor personnel had different understandings of where the latest information on changes to plant configurations were recorded. These same people, also did not agree on how soon after changes occurred, that they would appear on the applicable diagrams / drawing As a result of this identified confusion, the licensee issued a memorandum to file on May 22, 1987, entitled "sources to consult to confirm the existence and location of piping, components, and supports, San Onofre Nuclear Generating Station, Units 2 and 3". It appears that if all the applicable personnel are aware of this memorandum and its contents, this should reduce the confusio This item is close . . _ ~. -

The mercury check devices which are a component of rate-of-rise sprinkler systems, are made up' of two molded plastic parts which are bonded together, and over a period of' time have developed leaks in the bond are In response this November 5, 1986 ASC0A lotter, the licensee issued an independent safety engineering group (ISEG) operating experience evaluation form (ISEG Log Number 86-ISEG-222) dated April 22, 1987. In this evaluation reply, the licensee identified the following:

.

(1) The licensee had already issued a new revision to maintenance procedure S 123-I-8.155, in September of 1986, to adopt the option of applying lubricant to the applicable valve part (2) The licensee was not interested in retrofit of the valve (3) Review of the licensee fire protection (FP) systems, confirmed that the' subject mercury check device is nci used at the licensee facilit Based on review of applicable licensee documents, it appears appropriate action was taken on this ite This item is close (Closed) Open Item (50-362/GL-85-22) Generic Letter - Potential for Loss of Post-LOCA Recirculation Capability Dte to Insulation Debris Blockage
