2 Maintenance Observation (62703)

The inspectors observed maintenance activities and reviewed records to verify that work was conducted in accordance with approved procedures, Technical Specifications, and applicable industry codes and standards. The inspectors also verified that: redundant components were operable; administrative controls were followed; tagouts were adequate; personnel were qualified; correct replacement parts were used; radiological controls were proper; fire protection was adequate; quality control hold points were adequate and observed; adequate post-maintenance testing was performed; and independent verification requirements were implemente The inspectors independently verified that selected equipment was properly <

returned to servic Outstanding work requests were reviewed to ensure that the licensee gave priority to safety-related maintenanc The inspectors observed / reviewed portions of the following maintenance activities:

87-BASA1 Troubleshooting of 1-CAC-V23, Drywell 2 Inch Exhaust Valv MI-16-685H Diesel Engine Bicera Relief Valve Inspectio PM-ENG504 Emergency Diesel Generator Dowel Pin Inspection (87-AYUL1).

PM-84-385 Diesel Generator Building Masonry Wall Support Wall S No violations or deviations were identifie . Surveillance Observation (61726)

The inspectors observed surveillance testing required by Technical Specifications. Through observation and record review, the inspectors verified that: tests conformed to Technical Specification requirements; administrative controls were followed; personnel were qualified; instru-mentation was calibrated; and data was accurate and complet The inspectors independently verified selected test results and proper return to service of equipmen The inspectors witnessed / reviewed portions of the following test activi-ties:

.

The inspectors verified conformance with regulatory requirements by direct observations of activities, facility tours, discussions with personnel, reviewing of records and independent verification of safety system statu The inspectors verified that control room manning requirements of 10 CFR 50.54 and the Technical Specifications were me Control room, shift supervisor, clearance and jumper / bypass logs were reviewed to obtain information concerning operating trends and out of service safety systems, to ensure that there were no conflicts with Technical Specifications Limiting Conditions for Operations. Direct observations were conducted of control room panels, instrumentation and recorder traces important to safety, to verify operability and that parameters were within Technical Specification limits. The inspectors observed shift turnovers to verify

,

that continuity of system status was maintained. The inspectors verified I the status of selected control room annunciator Operability of a selected Engineered Safety Feature (ESF) train was verified by insuring that: each accessible valve in the flow path was in its correct position; each power supply and breaker, including control room fuses, were aligned for components that must activate upon initiation signal; removal of power from those ESF motor-operated valves, as identi-fied in Technical Specifications, was completed; there was no leakage of major components; there was proper lubrication and cooling water available; and a condition did not exist which might prevent fulfillment of the system's functional requirement Instrumentation essential to system actuation or performance was verified operable by observing on-scale indication and proper instrument valve lineup, if accessibl The inspectors verified that the licensee's health physics policies /

procedures were followe This included a review of area surveys, radiation work permits, posting, and instrument calibratio The inspectors verified that: the security organization was properly manned and security personnel were capable of performing their assigned functions; persons and packages were checked prior to entry into the protected area (PA); vehicles were properly authorized, searched and escorted within the PA; persons within the PA displayed photo identifica-tion badges; personnel in vital areas were authorized; effective compen-satory measures were employed when required; and security's response alarms was adequat ,

The listed LER was reviewed to verify' that the information provided met NRC reporting requirements. The verification included adequacy of event-description and corrective action taken or planned, existence of potential generic problems and the relative safety significance of the even '

With both units' operating at 100% of power and Diesel Generator No. 2 out; for maintenance, Emergency Bus E-2 supply breakers (master and slave) l opened on undervoltage at 3:10 p.m. on August 21, 1987. A technician {

installing a plant modification shorted a wire to ground, blowing a fuse .

!

to the bus undervoltage relay causing an undervoltage condition to be sense "B" Reactor Protection . System (RPS), was lost, causing a logic

"B" RPS trip, standby gas treatment 1A auto start, primary containment isolation system groups 2, 3 and 6 isolation and group one logic "B" trip, as well as isolation of the reactor building ventilatio All Unit 1 Division II Emergency Core Cooling Systems remained operable during the event. Unit 1 power was reduced to about 85% during the event due to decrease in condenser vacuum. The IB Steam det Air Ejector (SJAE) had been . lost and the 1A SJAE was placed in full load at 3:27 p.m. , the-operators transferred "B" RPS to the alternate power supply and the logic

.

"B" RPS trip was reset. The blown fuse was replaced and E-2 re-energized at 3:48 p.m. on August 21, 1987. All affected systems were returned to normal. .The inspector arrived in the control room 10 minutes after E-2 was lost and remained throughout the licensee's recover Unit 2 remained at 100% power throughout the event. Unit 2 lost power to the Residual Heat Removal (RHR) Division II injection valves and two j drywell coolers during the even j l

The inspector concluded that the operators' actions during the event were )

appropriate. The operators had some minor trouble locating procedures in
