Exit Interview
The inspection scope and findings were summarized on October 14, 1986, with
,
those persons indicated in paragraph 1 above. The licensee acknowledged the
inspectors findings. The licensee did not identify as proprietary any of the
material provided to or reviewed by the inspectors during this inspection.

Plant Status
!
Unit I completed a 29-day outage to replace the damaged L.P. turbine rotor.
Both L.P. turbine rotors were replaced.
The unit was taken critical and
,
i the generator placed on the line at low power on September 24, 1986. The l
generator was later taken off the line to balance the L.P. tu-Sine rotor and i
returned to power on September 25th. The full power upgrade for Unit I was l
completed on October 9, 1986.
I Unit 2 remained at or near 100% power for the entire reporting period.

Licensee Action on Previous Enforcement Matters (92702)
(Closed) Violation 338,339/86-17-01:
Failure to Have a Program Requiring Review of Design Change Acceptance Test for Technical Specification (TS)
Requirements. The licensee has revised Administrative Procedure 3.1 (dated 8/29/86) to incorporate this requirement.
(Closed) Violation 338/86-17-03: Failure to Perform Written Safety Evalua-tion.
The licensee has revised Administrative Procedure 14.1 (dated 7/31/86) to incorporate this requirement.
5.
Licensee Event Report (LER) Follow-Up (90712 & 92700)
The following LERs were reviewed and closed. The inspector verified that reporting requirements had been met, that causes had been identified, that corrective actions appeared appropriate, that generic applicability had been considered, and that the LER forms were complete.
Additionally, the inspectors confirmed that no unreviewed safety questions were involved and that violations of regulations or Technical Specification (TS) conditions had been identified.
(Closed) LER 338/86-13, Forced Shutdown Due to High RCS Unidentified Leakage.
The licensee determined the cause of the leakage and made the necessary repairs.
(Closed) LER 339/82-83, Emergency Diesel Generator "2J" Removed From Service for Six Hours and Eight Minutes to Replace Defective Underexcitation Alarm Relay. A Design Change, DCP 83-03, was completed 7-15-86 to correct the 40X relay problem.
6.
Monthly Maintenance (62703)
Station maintenance activities affecting safety related systems and components were observed / reviewed, to ascertain that the activities were conducted in accordance with approved procedures, regulatory guides and industry codes or standards, and in conformance with Technical Specifica-tions.
Charging pump 1-CH-P-1C continues to be out of service due to an oil leak.
(See paragraph 7 in inspection report 338,339/86-20) The changeout of the motor from 1-CH-P-1C to 2-CH-P-1B has been completed.
Charging pump 2-CH-P-1B is now operable.
Charging pump 1-CH-P-1A and 1-CH-P-1B have been determined by the licensee to be in the alert range due to high bearing vibration. This appears to be a continuing 7:oblem with the charging pumps and the inspectors will continue to monitor charging pump operatio l

The following radiation monitors remain out of service for Unit 1: SW 107 -
CC Heat Exchanger Service Water, RMS 161 - Containment High Range Gamma, and RMS 162 - Manipulator Crane.
No violations or deviations were identified.
7.
Monthly Surveillance (61726)
The inspectors observed / reviewed TS required testing and verified that testing was performed in accordance with adequate procedures, that test instrumentation was calibrated, that limiting conditions for operation (LCO)
were met and that any deficiencies identified were properly reviewed and resolved.
2-PT-24 - The inspectors reviewed the calorimetric surveillance for Unit 2.
On September 25, 1986, the inspectors observed performance of 1-PT-71.1
" Auxiliary Feed Pump Test".
After approximately two minutes of operation, the turbine driven auxiliary feed pump tripped and, according to the operators performing the test, the trip did not appear to be caused by an overspeed condition.
The licensee reperformed the test successfully on September 25, 1985, performing two successful pump starts. This auxiliary feed pump was also successfully started on October 3,1986.
The cause of the pump trip on September 25 could not be determined.
The licensee will continue to monitor feed pump operation and the inspectors will evaluate licensee actions.
No violations or deviations were identified.

ESF System Walkdown (71710)
The RWST on Unit 1 (an ESF system) was verified to be operable by performing a walkdown of the accessible and essential portions of the system on
October 8, 1986.
.
No violations or deviations were identified.
9.
Operational Safety Verification (71707)
By observations during the inspection period, the inspectors verified that the control room manning requirements were being met. In addition, the inspectors observed shift turnover to verify that continuity of system status was maintained. The inspectors periodically questioned shift personnel. relative to their awareness of plant conditions.
Through log review and plant tours, the inspectors verified compliance with selected Technical Specification (TS) and Limiting Conditions for Opera-tions.

In the course.of the monthly activities, the resident inspectors included a review of the licensee's physical security program.
The performance of various shifts of the security force was-observed in the conduct of daily activities to include: protected and vital areas access controls, searching of personnel, packages and vehicles, badge issuance and retrieval, escorting of visitors, patrols and compensatory posts.
In addition, the resident inspectors observed protected area lighting, protected and vital areas barrier integrity and verified an interface between the security organiza-tion and operations or maintenance.
,.
On a regular basis, radiation work perm'its (RWP)'were reviewed and the specific work activity was monitored to assure the activities were being conducted per the RWPs. Selected radiation -protection instruments were periodically checked and equipment operability and calibration frequency was verified.
The inspectors kept informed, on a' daily basis, of overall status of both units and of any significant safety matter related to plant operations.
Discussions were held with plant management and various members of the operations staff on a regular basis. Selected portions of operating logs and data sheets were reviewed daily.

The inspectors conducted various plant tours and made frequent visits to the Control Room. Observations included: witnessing work activities in progress; E
verifying the status of" operating acd standby safety systems and equipment; confirming valve positions, instrument and recorder readings, annuciator alarms, and housekeeping.
'
The inspectors reviewed the following completed procedures for compliance with the applicable requirements:
1-0P-1.5 - Unit Startup from Hot St'andby Condition (Mode 3) to Startup Condition (Mode 2) with Reactor' Critical'at less than 5% power.
1-0P-1.4 - Unit Startup from Hot Shutdown Condition (Mode 4) to Hot Standby Condition (Mode 3) at B,47 degrees Fahrdnheit.
1-0P-1.3
- Unit Startup from Cold Shut'down (Mode 5) to Hot Shutdown Condition (Mode 4) less than 350, degrees Fahrenheit.
1-0P-1.1 - Unit Startuo from Cold Shutdown Condition (Mode 6) less than 140 degrees Fahrenheit w'ith the Primary System. drained to Cold Shutdown (Mode 5)
No violations or deviations were identified.
