,e WALNUT CREEK, CALIFORNI A 94596 December 3, 1987 MEMORANDUM FOR: DN 50-312 FROM: L. Miller, Chief Reactor ProjectsSection II SUBJFCT: MINUTES FOR THE NOVEMBER 24, 1987 MEETING ON RANCHO

. SECO BETWEEN NRC AND SMUD REPRESENTATIVES TO DISCUSS PROCUREMENT, FIRE PROTECTION, AND CURRENT CONCERNS The following is a sumary of an infonnational meeting held on November 24, h - 1987 at the Region V office with representatives of the Sacramento Municipal Utility District (SMUD). The purpose of the meeting was to discuss SMUD's perception of their procurement program, the readiness of fire protection systems for restart, and current concerns. (An Agenda, Notice of Significant Meeting, and SMUD's presentation viewgraphs are enclosed.)

SMUD made a detailed presentation and regional representatives provided coment and questions. The following points were emphasized by SMUD representatives:

Bolting:

1. SMUD detennined that 64 bolts of the same type as those found by the NRC to be understrength were in the warehouse as spares. These bolts were A193 B7 Quality Class II bolts, with Clark Brothers bolt head markings, procured from Westinghouse in two lots. SMUD did not know how many bolts of this manufacture were installed in the plant. However, SMUD intended to complete an engineering study by December 15 to demonstrate that all non-safety related bolts actually installed in the plant were adequate for their intended service.

2. SMUD conducted a check for comingling of bolting material in the warehouse, but had "received no reports" of commingiing. This check was not documented, nor was it conducted in accordance with a written plan. SMUD also was unfamiliar with the inspector's detailed findings, and requested to be i

made aware of these. (Subsequent to the meeting, J. Dyer indicate.1 that of SMUD had been present when the ASTRP team was given the bolting material which the team had identified as potentially comingled. The detailed description of this material will be in Inspection Report 87-29.) ,

SMUD also stated that by November 30, 1987, all Quality Class 1 bolting material in the warehouse would be maintained physically segregated from other material (as opposed to maintaining different quality classes in the same drawer separated by dividers, the current SMUD practice).

3. SMUD conducted a 100% inventory of its warehouse stock, to identify all deficiencies in material identification and storage. of SMUD stated that the records of these deficiencies were available for review.

Materials Management: t

1. SMUD reported that an assessment of materials management practices had .

been conducted which concluded that past practices had not contributed to any degradation conclusion wasof safetyatrelated provided systems. ()No insight into the basis for this the meeting.

. Fire Protection:

1. SMUD indicated that the number of fire barrier breaches was significantly reduced, and very few breached barriers were expected by the scheduled restart date.

2. SMUD agreed to complete its evaluation of containment fire hose capacity by the end of December, and to submit this evaluation to NRR.

~

3. SMUD agreed to rcview the seismic design basis of the reactor coolant '

pump oil collection tank in view of the recent inspection finding that the tank itself was seismic category II rather than category I (as indicated in the SMUD SER submittal).

Other Topics:

1. SMUD agreed to perform a trainwise loss of offsite power test initiated

.I with a simultaneous loss of offsite power and safety injection initiation signal, including sequencing of safety loads onto the affected busses. .

2. SMUD also agreed to review the test envelope to ensure that the design j basis loading scheme was evaluated by this test.

3. SMUD indicated that their long term goal was to reduce the corrective '

maintenance backlog to one or two months of effort. (This appeared to be a change from the previous commitment to reduce the backlog to "as low as reasonably possible.")

i The Regional Administrator made several points, in addition to the NRC concerns noted parentMtically above:

i j 1. The SMUD review of the loss of offsite power test appeared cursory, in

view of the substantive NRC coments, and the failure by SMUD to have j considered these concerns prior to the NRC raising them. +

! 2. The delay by SMUD in establishing the loss of offsite power procedure in

final form suggested that preparations and training by personnel on the final procedure might be lacking due to its unavailability until the test was to be

! performed. "

r

3. The unavailability of acceptance criteria for the diesel generator vibration problem which has been identified suggested that SMUD was not participating actively enough in the resolution of this problem, but may have lapsed into allowing a contractor to have too much responsibility for the problem's definition and resolution.

4. The apparent change in SMUD's comitment to vigorously reduce the '

corrective maintenance backlog as low as possible prior to restart was disturbing. SMUD was requested to clearly define what level of corrective maintenance requests they were prepared to accept for restart to clarify this ambiguity.

5. The findings and recomendations of the B&W Owner's Group SPIP program and the SMUD EASTRP program should be completely reviewed by SMUD to ensure that all restart items have been identified and accomplished prior to restart.

The meeting was concluded with a sumary by Mr. Martin. He stressed the importance of SMUD developing an operating perspective as opposed to the h

construction perspective which had prevailed through most of the outage to the present. It was noted that SMUD had not yet demonstrated this orientation towards operations. Mr. Ferlit of SMUD agreed with these remarks, and reaffirmed SMUD's comitment to a high quality, safe restart of Rancho Seco.

RANCHO SECO NUCLEAR GENERATING STATION (Fire Barrier Breaches)

Graph Depicts as of the morning of 11-23-87 -

4 Electrical Breaches = 55 Mechanical Breaches = 1 Doors = 6 Dampers = 5 Total Breaches = 67 Note: Since printing of graph 24 additional penetration seals were restored to operable status and/or removed from the report due to not being Technical Specification required. This brings the total inventory of penetration down to the following:

Mechanical / Electrical = 33 Breaches Doors = 6

CO2 FIRE PROTECTION SYSTEMS (Operability Status) 22 Total Technical Specification Required Systems Restart Projection

, All systems are expected to be operable.

4 As a compensatory measure to ensure compliance with administrative process for entrance / exit into CO2 zones, fire watch patrols have been established assuming system automatic features are inoperable.

When system automatic features are technically inoperable, fire detection and manual operating features of the CO2 systems remain operable.

post Restart Corrective Actions Modification to CO2 systems to include flashing red lights, abort stations and removal of the system isolation switches from the CO2 panels.

Following the above modification and associated procedure revisions, the fire watch patrols will be eliminated.

• CO2 zone entry will occur with systems in service.
