. Docket No.: 50-315 Unit Name: D.C. Cook Unit 1 Completed By: A. S. Puplis Telephone: (616) 465-5901 Date: June 10, 1985 Page: 1 of 1 MONTHLY OPERATING ACTIVITIES - MAY, 1985 HIGHLIGHTS:

The reporting period began with the reactor vessel closure head removed. At 0910 on 5-02-85, the upper reactor internals were removed and at 0635 on 5-03-85, tuel movement from the reactor vessel to the spent fuel pool was begun. The core was fully unloaded by 0750 on 5-07-85. The reporting period ended with the core tully unloaded.

There was no electrical generation in the month of May.

Summary:

5-02-85 At 0910, reactor internals were removed from core and placed in storage.

5-14-85 At 1338, an Unusual Event was declared due to a hydrazine leak in the #1 and #4 Feedwater Gallery. At 1850, the Unusual Event was terminated.

5-23-85 At 0922, the Control Room Cable Vault Halon System was actuated. It was caused by grinding in the area. All personnel were evacuated.

The Unit 1 Control Room Cable Vault Halon System was inoperable as of 1400 on 4-05-83. The backup CO system for the Control 2

Room Cable Vault remains operable.

DOCKET NO. 50 - 315 UNIT NAME D. C. Cook - Unit No. 1 DATE 6-7-85 COMPLETED BY B. A. Svensson MAJOR SAFETY-RELATED MAINTENANCE MAY, 1985 M-1 Corrected leak-by condition on Valve 1-FW-181 feedwater line drain valve at containment penetration, by machining new seating surfaces on valve body and plug. Valve was repacked and returned to service.

M-2 Removed hand-hole covers and tube-lane blocking devices from steam generators 11, 12, 13 and 14. Repaired welded undercut on welds made on split plates and 3/8" blocks. Welds were inspected by Q.C.

M-3 Ground out and repaired cracks in cladding on east centrifugal charg-ing pump. Welds were inspected by Q.C.

M-4 Replaced valve bonnet on the isolation valve to PPP-303 transmitter.

Valve was retested for operability.

M-5 Replaced SI-126, seal welded bonnet Rockwell check valve with a Con-val clamp seal check valve.

M-6 Replaced bearing on lower containment access outer door. Door was inspected following repairs.

M-7 Replaced bonnet assemblies on CS-359 and CS-360, seal water filter drain valves. Adjusted travel stops as required.

M-8 Replaced diaphragms on the following valves: CS-357, seal water re-turn filter inlet; CS-361, seal water return filter outlet and CS-356, seal water return filter bypass.

M-9 Replaced body-to-bonnet gasket on 1-RH-104E. Also added 4 rings of packing to 'E' RHR pump suction from recirculating sump.

M .1 0 Repaired XRV-228 and found piece of metal in seat of valve. Lapped seat and tested good, XRV-228 is pressure regulator for 1-CD Diesel Turbo Charger.

M-11 On 1-CD Diesel Generator, disassembled 3-way temperature control valves in lube oil and jacket water coolers. Installed new thermo-stats and 0-rings.

M-12 Due to excessive leakage; replaced packing, body-to-bonnet gasket, and trim assembly on QRV-303. Three-way valve on inlet of volume control tank was retested for oper. ability.

M-13 CCW-180W, Inlet to "W" RHR Heat Exchanger could not be isolated during ISI hydro. Installed new valve after removal of old valve showed that seat needed replacing.
