"Attended exit interview Exit Interview The inspection scope and findings were summarized on June 12, 1987, with those persons indicated in paragraph 1 above.
The licensee did not identify as proprietary any of the materials provided to or reviewed by the inspectors during this inspection.
Plant Tours (Units 1 and 2)
The inspectors conducted plant tours periodically during the inspection interval to verify that monitoring equipment was recording as required, equipment was properly tagged, operations personnel were aware of plant conditions, and plant housekeeping efforts were adequate.
The inspectors also determined that appropriate radiation controls were properly established, critical clean areas were being controlled in accordance with procedures, excess equipment or material was stored properly and combustible materials and deb~is were disposed of expeditiously.
During
tours, the inspectors looked for the existence of unusual fluid leaks, piping vibrations, pipe hanger and seismic restraint settings, various valve and breaker positions, equipment caution and danger tags, component positions, adequacy of fire fighting equipment, and instrument calibration dates.
Some tours were conducted on backshifts.
The inspectors routinely conducted partial walkdowns of ECCS systems.
Valve, breaker/switch lineups and equipment conditions were randomly verified both locally and in the control room.
During the inspection period the inspectors conducted a
complete walkdown in the accessible areas of the Unit
and 2 diesel generator and component cooling water systems to verify that the lineups were in accordance with licensee requirements for operability and equipment material conditions were satisfactory.
Additionally, flowpath verifications were performed on the following systems:
Unit 1 and 2 chemical and volume control, spent fuel pool purification, refueling water tank, and high pressure/low pressure safety injection.
Plant Operations Review (Units 1 and 2)
The inspectors, periodically during the inspection interval, reviewed shift logs and operations records, including data sheets, instrument traces, and records of equipment malfunctions.
This review included control room logs and auxiliary logs, operating orders, standing orders jumper logs and equipment tagout records.
The inspectors routinely observed operator alertness and demeanor during plant tours.
During routine operations, operator performance and response actions were observed and evaluated.
The inspectors conducted random off-hours inspections during the reporting interval to assure that operations and security remained at an acceptable level.
At least once per week, one inspector arrived on site during early morning hours to check for inattentiveness of personnel as has been observed as several other facilities.
No deficiencies were found although it is standard practice for the security force to alert other personnel to the presence of an NRC inspector on-site.
Shift turnovers were observed to verify that they were conducted in accordance with approved licensee procedures.
The inspectors performed an in-depth review of the following safety-related tagouts clearances):

Technicial Specification Compliance (Units 1 and 2)
During this reporting interval, the inspectors verified compliance with limiting conditions for operations (LCO's)
and results of selected surveillance tests.
These verifications were accompli shed by direct observation of monitoring instrumentation, valve positions, switch positions, and review of completed logs and records.
The licensee's compliance with LCO action statements were reviewed on selected occurrences as they happened.
6.
Maintenance Observation Station maintenance activities of selected safety-related systems and components were observed/reviewed to ascertain that they were conducted in accordance with requirements.
The following items were considered during this review; limiting conditions for operations were met, activities were accomplished using approved procedures, functional tests and/or calibrations were performed prior to returning components or systems to service; quality control records were maintained; activities were accomplished by qualified personnel; parts and materials used were properly certified; and radiological controls were implemented as required.
Work requests were reviewed to determined status of outstanding jobs and to assure the priority was assigned to safety-related equipment.
The inspectors observed portions of the following maintenance activities:
Unit 1 Work Orders 4448 4493 4568 Reactor Building Emergency Exhaust Fan, HVA-9A -
PM 1B Charging Pump Motor - Quarterly PM Diesel Generator Fire Protection System
. Surveillance Unit 2 Work Orders 6217 6351 6354 Auxiliary Feedwater Flow - Channel Check Safety Injection Tank Instrumentation - Functional Tests Auxiliary Feedwatet Actuation System - Surveillance 7.
Review of Non-routine Events Reported by the Licensee ( Units 1-and 2)
Non-routine plant events were reviewed for potential generic impact, to detect trends, and to determine whether corrective actions appeared appropriate.
Events which were reported immediately were also reviewed as they occurred to determine that technical specifications were being met and that the public health and safety were of upmost consideratio On May 21, 1987, Unit 1 reactor tripped from 1005 power due to a turbine generator lockout trip.
The turbine lockout trip was caused by an increase in exciter field current.
Initial investigation found one pinched and one bare wire in a current transformer which if grounded to the transformer case could have caused the increase in exciter field current.
The wires were replaced and the Unit returned to service.
Westinghouse representatives are on site and will continue to monitor the exciter.
All reactor systems responded normally.
On May 27, 1987, two control rods in the Unit 2 reactor dropped to the bottom of the core for no apparent reason.
This is the second time in the past 30 days that these same two rods (5 and 7)
have malfunctioned.
In accordance with plant procedures, the reactor was shutdowm and placed in Mode 3.
Troubleshooting by the licensee did not reveal the cause.
However, one printed circuit board which is common to both of the affected control rods was replaced and was sent to Combustion Engineering Laboratories for investigation.
The control rods were recovered during a
normal reactor startup and the unit was returned to service.
The Licensee is continuing to monitor rods
and 7 for any further indication of aberrant behavior.
Physical Protection (Units 1 and 2)
The inspectors verified by observation and interviews during the reporting interval that measures, taken to assure the physical protection of the facility met current requirements.
Areas inspected included the organization of the security force, the establishment and maintenance of gates, doors and isolation zones in the proper conditions, that access control and badging was proper, and procedures were followed.
Survei,llance Observations During the inspection period, the inspectors verified plant operations in compliance with selected technical specifications (TS)
requirements.
Typical of these were confirmation of compliance with the TS for reactor coolant chemistry, refueling water tank, containment pressure, control room ventilation and AC and DC electrical sources.
The inspectors verified that testing was performed in accordance with adequate procedures, test instrumentation was calibrated, limiting conditions for operations were met, removal and restoration of the affected components were accomplished, test results met requirements and were reviewed by personnel other than the individual directing the test, and that any deficiencies identified during the testing were properly reviewed and resolved by appropriate management personnel.
The inspectors observed portions of the following surveillance(s):
