Quality Assurance Program Examination (35701)
The inspector examined portions of the licensee's quality assurance program to ascertain whether personnel responsible for developing and implementing QA procedures were familiar with changes to the QA program, to :ascertain whether revisions to implementing procedures are in conformance with the QA program' changes, and to ascertain whether the licensee is implementing a QA program that is in conformance with regulatory requirement The inspector reviewed the QA program'document hierarchy at San Onofre with key personnel responsible for the program implementatio Specifically the QA program description, Topical Report SCE -
1A dated July, 1985, was reviewed as was the Topical Quality Assurance Manual through revision 85-09 dated September 13, 198 The next lower level of QA 'implementing documents at the San Onofre site are called "QA reference procedures", which are issued as a "QA Reference Procedures Manual" by each of the SCE organizations'irvolved in safety related' work. The involved organizati6ns include the Station, Procurement and Material Management, Advanced Engineering, Engineering and Construction/Nuclear Engineering, Safety 'and Licensing Department, Fuel Supply, Quality Assurance, and 'Shop and Test. Each of these organizations (in one or more forms) maintains a "QA Reference Procedures Manual" in which the QA program implementing.'procedures are contained. There are literally hundreds of QA implementing procedures issued by the involved organization The inspector reviewed some of the licensee's QA procedures for administering the QA department review of QA implementing procedure The inspector found these generally adequate. From an examination of procedure review logs the inspector determined: that 'review personnel were utilizing the mandated logs per procedure and from a review.of revised
implementing procedure, the inspector determined that required reviews
were being performed and documents were formally approved. The nature and number of document review comments were a clear indication that reviews were performed conscientiously and not perfunctoril The site QA program implementation had been previously sampled and verified in inspections conducted in March, April, July, and August 1985, which examined QA.implementation in the areas of Procurement Control (38701), Materials Control (38702), Onsite Review Committee (40700),
Offsite Review Committee (40701), and the Audit Program (40702).
Additionally, the inspector verified that the licensee has an administrative control program for controlling new and existing regulatory commitment These specifically include the computerized systems of the San Onofre Commitment Register (SOCR) and the Licensing Commitment List No violations or deviations were identifie.
Licensee Actions on Previously Identified Items (Closed) -IB Bulletin 80-06, Engine red Safety Features (ESF) Reset Controls Unit 1, The, remaining actions to complete this bulletin are fully.described
- in report 50-206/85-134. The -rem Iaining action (to rework the control circuitryfor valves MOV-1-100 BC,D,) was committed to be done during th eUnit 1 cycleIX refueling".
- ,Pending the completion, of that actioh the bulletin is considered closed and the-remaining action will be tracked as a follow up item (50-206485'-31-01).. (Closed) Violation 50-206/85-13-01, RIR Valve Studs Were Replaced Without a Proper DEsign Change Review for a Change.to a Lower Strength Material The licensee's response to the notice of violation was provided in a July 8, 1985:,letter to the NRC (Baskin to Martin).
The letter states the cause of the violation was a failure to follow procedur Licensee actions takeh included:
o An investigation to identify any additional components which had the stainless steel bolts installed; o
An-analysis of bolt stresses; o
Initiation of plans for formal maintenance planner training in the area of design change control;
Plans for enhancement of the work review process (ASME Section XI traveler) to prevent improper design changes; o
A review of Units 1, 2, and 3 maintenance orders for other improper material changes;
o Replacement of the improper bolts with proper bolt The inspector reviewed the licensee's actions taken-as follows:
o The investigation to determine if other studs were improperly replaced revealed eleven additional case The analysis of bolt stresses showed several cases where the
'bolts had been stressed to beyond yield strength for the material. The licensee immediately replaced those studs and bolts. The overstressed condition was due to the bolt torque values applied during assembly, not due to operational loads.,
The licensee response states that stress values achieved did not affect the operability of the components in question. The licensee s calculations will be reviewed by other NRC personne to assess~the calculational methodology. Follow up item (50-206/85-31-02).
o Maintenance planner,training is planned by.the licensee as.part of the overall training program improvements to achieve INPO accreditation. The formal program is being revisedto include specific elements. regarding design change cohtrol for maintenance personnel. The action item is scheduled for completion on.November 1, 1985 and is being tracked in the li'censee',s.commitment tracking system. The inspector satisfied himself that maintenance planners had been made aware of the potential design significance of material changes made by maintenanc 'The enhancement'made to the Section XI traveler review process for material changes was reviewed. It consisted of an addition to Administrative Guide.#Lrevised June-20, 198 The addition requires.QA personnel to review drawings to assure correct materials "are use o Jhe review of other maintehance.' orders for other improper-material changes cofisisted of computer "key word" searches of th maintenance order' and quality assurance information system-data bases'.
The, tems identfied as potential material changes were manually.reviewed by'-the licensee and determined to 'b authorized djesign changes:
o The replacement schedule for improper material was reviewe All item stressed beyond yield were replaced by May 20, 198 All other items will' be replaced by no later than the outage commencing November 20, 198 This item is considered closed. No additional violations or deviations were identifie '4 Exit Interview An exit interview was conducted on September 20, 1985 with the persons denoted in paragraph 1.
