SUMMARY An Enforcement Conference was held at Region II on August 25, 1986,..at 1:00 p.m.~,

EDT to review items pertaining to the Sequoyah Surveillance Program. TVA gave chronology of the Surveillance Review Program since, August 1985.' The program is in its fourth evolution, the latest having started in June 1986. The program requires that review of all surveillance instructions for technical adequacy be completed prior to restart. TVA stated they neither = feel their surveillance .

program was out of control' nor did they have a programmatic breakdown in this program. TVA believes their present review program is adequ~ ate and will identify and correct any procedural problems. The slides used by TVA during the pre-sentation are contained in the attachmen .

R. W. Fortenberry, Technical Support Supervisor, Sequoyah Nuclear Plant J. M. McGriff, Branch Chief, EI & Controls - SI Review Coordinator T. A. Ippolito, Consultant, DBA Event-Discussions-The Regional Administrator opened by reviewing the NRC concerns on the surveillance progra ihe Directcr of TVA Projects expanded on the con-ceins, briefly describing the surveillance deficfencies identified by both TVA and NRC during late 1985 and 198 Mr. C. -C. Mason, Deputy Director of clear Power, gave brief opening statements for .TVA. Mr. P. R. Wallac , ave an opening overview of the surveillance - program history. Mr. M. E. Frye gave a detailed presenta-tionlof the surveillance program review from August 1985 until present. *

.

TVA stated that their review of QA Audit Reports, NRC Inspection Reports, and Reportable Event History Files prior to August 1985 did not indicate generic problems. The review program started in August 1985 with a one for one check between Technical Specification Requirements and Surveil-lance Instructions (nine deficiencies identified). Based on problems associated with the 6.9 kv penetration testing, the program was revised in February 1986 to include random sampling of -137 surveillance require-c.ents (minor discrepancies). Based on failure to implement a surveillance requirement on the manual SI hand switch, the program was revised again in March 1986 to include a Task Forc A revised Technical Review Program was added to the ongoing Administrative Program in June 1986. TVA stated that the Technical Review Program will be completed prior to startu The NRC stated that the licensee should be identifying and correcting their own problem The NRC questioned if TVA is now identifying tneir own problems only because of programs the NRC has forced upon them, and if TVA is now convinced that they have had a programmatic breakdown in the surveil-lance area. Mr. P. R. Wallace answered that he did not feel the program was out of control nor that a programmatic breakdown had occurred. He did not believe that these problems represented widespread problems, but isolated example Mr. Wallace stated that the reason that prior QA reviews had not been effective in picking up problems was that QA had not been staffed for or tasked with an in-depth Technical Review. QA involvement from a technical standpoint started in June 1986. The technical people now assisting QA in the review include some Watts Bar personnel that are familiar with earlier Watts Bar type surveillance problem The NRC generically questioned ASME Section XI Pump Performance Testin The question was in regard to operators deviating from procedures to obtain acceptable ERCW pump performance data. TVA responded that the Independent Safety Engineering Group (ISEG) had investigated this issue and found no other such occurrence The NRC thanked TVA for their presentation and closed the meetin Attachment: Enforcement Conference Agenda l

PROBLEM Through TVA reviews and NRC inspections performed since August 1985

- Three specific problem areas

- Some examples Surveillance Requirements not implemented

- SI hand switch not tested for manual trip

- 31 day ESF circuitry test Surveillance Requirements not properly implemented in procedures

- Molded case circuit breaker testing

- Undervoltage and underfrequency functional test Implementation of surveillance program

- Review of test data failed to identify recurring problems

- Test results were not reviewed in a timely manner

- Procedure not properly performed (i.e., ERCW pump test)

BACKGROUND Through an evolutionary process with heavy management envolvement:

- From August 1985 (both units in mode 5)

- June 1986 (Full technical review program)

Prior to August 1985 no indications of generic problems:

- TVA QA Audit reports

- NRC inspection reports

- Reportable event history files A'ugust 1985: Because of findings at Watts Bar

- Two year program developed (July 1987)

- Check list developed

- Section supervisor lists and schedules

- Intent: Technical and Administrative February 1986: Suplemental steps taken due to problems associated with 6.9KV penetration testing

- Random sample of 137 Surveillance Requirements

- Minor discrepancies (no safety concerns)

March 1986: Identified failure to implement a surveillance requirement on the manual SI handswitc SR/SI Task Force implemented

- Ensure implementation of every surveillance requirement

- Approximately 180 items identified

- Ten items reported to NRC (LER)

- Final report issued June 1986: Results of the SR/SI task force, and testing of molded case circuit breakers

- Further acceleration of review process

- Complete technical review program

- Technical review checklist

- Prior to restart L _ _ _ __-
