P. Hiland, Acting Senior Resident Inspector G. O'Dwyer,; Resident Inspector Inspection of Unit 2 Preservation Activities (92050)

The inspector. reviewed the licensee's procedures for maintaining stored-in-place plant equipmer:t, material in the laydown areas

, and components and material within the warehouse complex. These procedures delineate the requirements, responsibilities and activities necessary to preserve th.e plant structures, systems, components and materials until the resumption of plant construction. The procedures also include specific instructions for development of instructions for individual component' inspections and maintenanc i The' inspector performed a walkdown inspection of the Unit 2 power bloc 'The areas inspected during the walkdown were the inner and outer drywells, refueling floor, pump rooms, auxiliary building, control building, and intermediate building. The components observed during the inspection were:

'

-reactor pressure vessel reactor recirculating pumps and motors RHR pumps and motors RHR heat exchangers L divisions 1, 2'and 3 diesel generators and control panels

'i refueling crane 480 volt switchgear valves piping assemblies (spools)

.

Each component inspected had a copy of the latest in-storage maintenance order attached to the component. All required maintenance had been performed within the specified dates determined by procedures and the preservation engineer. Covers were in place, purges were being maintained on tanks and heat exchangers, and electric motor and switchgear heaters

'were energize Pipe, pipe assemblies, HVAC ducts and structural steel in the laydown areas were off the ground and on dunnage. The inspector observed some areas of rust on ungalvanized areas in the HVAC ducts and heavy rust inside several of the larger diameter pipes. The rust accumulation had been identified by the licensee's quality inspectors during their April 1989 surveillance of the laydown areas. The licensee representative stated that the rusting would be addressed during this summer's laydown area maintenance cycl Comoonents' stored in the Unit 2 level B and C warehouse were being mait.tained to the standards established by the respective manufacturer No Unit 2 material was stored in the level A storage area. Heaters were energized in the large electrical components, desiccants were replaced at manufacturer recommended intervals and nitrogen purges were maintained at the required pressures. Housekeeping was good in all .

' area The inspector reviewed quality inspection records, material transfer records and maintenance records for Unit 2 equipment. The material transfer authorization is used to control the transfer of Unit 2 components to Unit 1. Transfers were further controlled, documented and tracked by quality assurance through the use of nonconformance report No violations or deviations were identifie . Unit 1 Drywell Cable Damage (62705)

The inspector examined cables removed from conduit in the drywell that had been subjected to excessive temperatures during plant operation The conduit location was in an area having inadequate insulation that

,

permitted heat from the reactor vessel to reach some parts of the

'

conduit. The heat caused embrittlement of the Hypalon cable jacket There was no visible damage to the cross-linked polyolefin conductor insulation and insulation resistance (megger) tests were in acceptable ranges. The licensee's corrective actions will include the replacement of damaged cables, the installation of additional insulation and the installation of additional temperature monitors to detect high temperature spots in the drywel . Unit 1 Motor Operated Valve Inspection (62705)

The inspector reviewed the licensee's documents which delineate those items to be inspected and verified in each motor operated valve included in the motor operated valve reinspection program and which provide a record of valve component configuration to assure that qualified components are installed in each valv No violations or deviations were identifie l w_-________-_-___-_____-_____-___ _ _ _ _
