We following report highlights the operating experience of Wolf Creek Generating Station for the month of December, 1985. Wis report is being provided pursuant to 'Ibchnical Specification 6.9.1.8.
I.
SLNMARY OF OPERATING EXPERIENCE During the entire month of December, the unit operated in Mode 1, Prer Operation, bringirg Wolf Creek's record continuous days on line co eighty-one days. Two significant load reductions occurred in December. One was necessitated by cmulative penalty deviation time as a result of the Axial Flux Difference being outside the required target band; and the second was a planned load reduction for troubleshooting the turbine oil pump on Main Feedwater P ep "A".
II.
MAJOR SAFETY REIATED MAINTENANCE ACIIVITIES W e major safety related maintenance activities performed during the nonth of December included the semi-annual maintenance of the reactor trip breakers aM the smi-annual oil change on Centrifugal 01arging Pep " A". In addition, oil leakage on both Centrifugal Charging Pumps "A" and "B" was corrected.
III. CHANGES, TESTS, AND EXPERIMENTS ne following is a brief description of safety evaluations performed pursuant to 10 CFR 50.59 on changes, tests, and experiments durirg the month of Decenber.
l h
1.
'Ibmporary Modification 85-504-WS - Originated to al ow t e installation of temporary drain lines, along with the associated fittings and valves, on Service Water System Strainers lWS0lFA &
B.
No unreviewed safety or environmental questions are generated as a result of this temporary modification.
2.
Safety Evaluation 85-SE-110 - Originated to allow the lifting of a lead frm ra3iation monitor BM-Rr-25 to prevent the initiation of a Stean Generator Blowdown Isolation Signal while troubleshooting was being performed. Automatic actuation of the Stean Generator Blowdown Isolation valves remained available via reduMant radiation monitors SJ-RE-02 and BM-RE-52.
No unreviewed safety or environmental questions are generated as a result of this temporary modification.
3.
Safety Evaluation 85-SE-lli - Originated to allow the attachment of a hose to the leakoff line on valve LF-EV-96, contairsnent outside isolation valve in the line leading from the contaianent nonnal sumps to the floor drain tank. The addition of the drcin hose is for the purpose of routing leakage to the floor drain to avoid contaninating the floor, and does not affect operation of the subject valve, or any other component. No unreviewed safety or environental questions are generated as a result of this temporary modification.

I 4.
Plant Modification Request 91149, Revision 0 - Originated to allow the installation of larger capacity hydraulic fluid reservoirs on the Main Steamline Isolation Valves, AB-HVll, 14, 17, and 20 and on the Main Feedwater Isolation Valves, AE-HV39, 40, 41 and 42, actuators to stop hydraulic fluid leakage during periodic maintenance. m is plant modification also added local pressure gauges on the hydraulic fluid lines to simplify maintenance. No unreviewed safety or environmental questions are generated as a result of this modification.
5.
Plant Modification Request 01185, Revision 2 - Originated to allow the a$dition of fire wrcp therno/ lag material on cables to eliminate IEFE 384-1974 separation violations between conSuits (4J1106,1U3A2C, 4U3E7N,1U1119 and lJ3A) and the exposed cables on ridiation monitors (Gr Rr22, GT Rr31, GT Rr32 and GT RT41). No unreviewed safety or envirormental questions are generated as a result of this modification.
6.
Plant Madification Request 01426, Revision 0 - Originated to change the valve identification number on the valve associated with the Auxiliary / Fuel Building Normal Fan Exhaust Filter Adsorber Unit (FGID2) frca 1GL-V-750 to 1GIr-V-760 to eliminate duplication of valve identification ntubers. No unreviewed safety or environmental questions are generated as a result of this modification.
7.
Plant Modification Request 01440, Revision 0 - Originated to allow the addition of flanged connections t.pstream ard downstream of Gaseous Radwaste System drain traps, FHA 04 and FHA 05 to simplify maintenance on the traps. No unreviewed safety or environmental questions are generated as a result of this modification.
8.
Plant Modification Request 01443, Revision 0 - Originated to allow the addition of two manual valved drains to each actuator hydraulic reservoir drip pan on the Main Steamline Isolation valves and the Main Feedwater Isolation Valves to prevent insulation contamination. No unreviewed safety or envirormental gaestions are generated as a result of this modification.
9.
Plant Modification Request 01445, Revision 0 - Originated to allow the installation of threaded pipe caps as per design on the outlet of valves AQ-V832, V879, V880, V912, V914, V920, V943, V968, V970 and V991, of the Condensate and Feedwater Gemistry Control-Systen. h is Plant Modification also removed in31 cation of a flow path frcm the discharge of valves AQ-V879, V920, V943, V970 and V991 to the oily waste system from the design drawings, as the oily waste system is incapable of handling / processing the chemicals discharged through these valves. No unreviewed safety or envirornental questions are generated as a result of this modification.

- 10. Plant Modification Request 01446, Revision 0 - Originated to re-install flow elments 94-FE924, 925, 926, and 927, which are currently installed backwards. Wese elements are used to balance flow in the safety injection system boron injection lines to the Reactor Coolant System cold legs. W e use of reverse-installed flow element differential pressure (aP) reMings for balancing purposes is acceptable as a P measurements between the parallel lines are cmpared on a relative (in H 0) basis rather than on an 7
absolute (gpm) basis. Absolute flow (gpm) is measured as total flow on another flow element, Di-FE917A or B.
W is modification indicates that the flow elements will be re-installed correctly prior to any future flow balance testing or during the next refueling outage. No unreviewed safety or environmental questions are generated as a result of this modification.
- 11. Plant !bdification Request 00577, Revision 3 - We original R4R and Revisions 1 and 2, as reported in March,1985, doctnent the Mdition of a recirculation line with a pressure regulated control valve arri the Mdition of a liquid drain trap on the suction line to each Waste Gas Compressor, SHA02A and B, to prevent loss of units with inadvertent closed discharge. Revision 3 provides engineering disposition to certify conformance of purchased and installed valves with Regulatory Guide 1.143, Table 1 requirements of D-Augmented Special Scope lines. No unreviewed safety or envirornental questions are generated as a result of this modification.
