We following report highlights the operating experience of Wolf Creek Generatiry Station for the month of September,1986. This report is beirg provided pursuant to Technical Specification 6.9.1.8.

I. SUMARY OF OPERATING EXPERIENCE

%e plant operated in mde 1, Power Operation throtshout the month of September. No significant forced power reductions occurred in Septenber.

II. MAJOR SAFEfY RELATED MAINTENANCE ACTIVITIES Major safety related maintenance activities include the replacenent of the actuator on the Control Roan Air Conditioning Unit valve GKV765, connencement of MOVATS testing of Auxiliary Feedwater valve Limitorque operators, replacement of a Solid State Protection Systen universal logic card and replacement of NF039A power supply. ,

III. CHANGES, TESTS, AND EXPERIMFNPS

%e followirg is a brief description of safety evaluations performed pursuant to 10 CFR 50.59 on changes, tests, and experiments during the month of Septenber.

1. Safety Evaluation 86-SE-92, Revision 1 - Originated to restrict movanent of equipnent thru the tenporary personnel access route-thru Iban 1403 during the refueling outage. No unreviewed safety or environnental questions are generated as a result of this revision to a temporary modification.

2. Safety Evaluation 86-SE Originated to change the computer setpoints to comply with Amendment No. 1 to the NCGS Technical Specification which allowed Power Distribution Control by a methodology called Relaxed Axial Offset Control. No unreviewed safety or envirorrnental questions are generated as a result of this computer setpoint change.

3. Safety Evaluation 86-SE-ll6 - Originated to tenporarily install a skid nounted air canpressor to supply the service and/or instrunent air systems. No unreviewed safety or environmental questions are generated as a result of this tenporary modification.

4. . Safety Evaluation 86-SE-ll7 - Originated to defeat blowdown and j sanple isolation caused by spurious alarms on process raiiation monitor BM-RE-52, since blowdown flow is not being routed thru the discharge path monitored by BM-RE-52. No unreviewed safety or enviromental questions are generated as a result of this tenporary nulification.

5. Safety Evaluation 86-SE-ll8 - Originated to tenporarily fill the electro-hydraulic actuator for valve GKV765 in the Control Room air conditioning unit with commercial grade hydraulic oil SCH824 manufactured by Mobil Oil Co. No unreviewal safety or environnental questions are generated as a result of this tenporary modification.

6. Safety Evaluation 86-SE-119 - Originated to tmporarily encapsulate a non-safety related 1 inch drain line on the main stem line piping down strem of the Main Stem Isolation valves.

No unreviewed safety or environmental quesitons are generated as a result of this temporary modification..

7.. Safety Evaluation 86-SE-123 - Originated to temporarily provide power to process radiation monitor BM-RE-52 from a convenience outlet to determine if .its nomal power is the cause of its spurious alarms. (See Safety Evaluation 86-SE-ll7) . No unreviewed safety or environmental questions are generated as a result of this temporary modification.

8. Safety Evaluation 86-SE-124 - Originated to temporarily install an isolation transformer in the power supply line to process radiation monitor BM-RE-52 and its normal power supply from breaker PG17LBF315. (See Safety Evaluations 86-SE-ll7 and 86-SE-123). No unreviewed safety or environmental questions are 1

generated as a result of this temporary modification. '

9. Safety Evaluation 86-SE-125 - Originated to temporarily. provide power to process radiation monitor BM-RE-52 from a convenience

.. outlet. Fluctuations in its normal power supply are causing spurious alarms. An attempt to filter these fluctuations with an isolation transformer (See Safety Evaluation 86-SE-124) was unsuccessful. No unreviewed safety or environmental questions are generated as a result of this temporary modification.

10. Safety Evaluation 86-SE-127 - Originated to temporarily install a camercial grade electric hot water heater which could be valved into the domestic water system to supply showers and sinks in the i Health Physics area upon loss'of normal hot water. No unreviewed j safety or environmental questions are generated as a result of 4

this tmporary modification.

11. Plant Itdification Request 01722 - Originated to verify and/or modify the motor operated valve switch settirgs . No unreviewed i safety or environmental questions are generated as a result of this plant raodification.

j 12. Plant Pbdification Request 01754 - Originated to remove the i special instrtsnentation that was built into Stem Generator "D".

l No unreviewed safety or environmental questions are generated as a l result of this plant modification.

13. Plant Modification Request 01793 - Originated to replace the

failed actuator on Control- Foon air conditioning unit valve GKV765 with one having a different model nunber. No unreviewed safety or i enviromental questions are generated as a result of this plant modification.

i 14. Safety Evaluation 86-SE-130 - Originated to temporarily install porous disk snubbers in the instrument lines on the emergency diesel engines jacket water punp and intercooler punp. No unreviewed safety or environmental questions are generated as a l

result of this temporary modification.
