MEMORANDU'i FOR: F. J. Miraglia, Jr., Director, Division of Pressurized Water Reactor Licensing B, NRR E. L. Jordan, Director, Division of Emergency Preparedness and Engineering Response, IE i FROM: Charles E. Norelius, Director, Division of Reactor Projects, Region III

SUBJECT:

LOSS OF FEEDWATER EVENT STATUS - DAVIS-BESSE Attached for your information is our monthly status report of activities at Davis-Besse relating to the Loss of Feedwater Event on June 9, 1985.

Activities relating to corrective actions on equipment that malfunctioned on June 9, 1985, and evaluations and repairs of safety-related hangers and supports are continuing. Inspection and repair of Raychem safety-related electric wire splices is in progress. All three new Reactor Coolant Pump shafts are now on site and the licensee has completed preparations for installing the shafts. The strike by operations and maintenance personnel represented by IBEW local 245 was settled on July 18, 1986, and all personnel are back to work. The unit outage completion date is projected to be November 6, 1986. The NRC Restart Test Review Group is on site reviewing the licensee's restart program and observing testing activities.

If you have any questions, please call me or Nick Jackiw of my staff (FTS 388-5697).

REGION III STATUS REPORT.

DAVIS-BESSE LOSS OF FEEDWATER EVENT AUGUST 4, 1986 Plant Status The plant remains in cold shutdown. The primary system is filled with a nitrogen bubble in the pressurizer.

Restart Activities MOVATS testing, envircnmental qualification work and other maintenance activities continue on the 165 safety-related motor-operated valves onsite.

The licensee has completed all planned work on 150 valves and returned them to service.

The NRC test review team continues to provide coverage of licensee testing activities. The licensee's System Review and Test Program (SRTP) includes 284 tests of which 15 will be performed following criticality. This program consists of 170 existing, or modified, surveillance tests and 114 new test procedures. To date 118 tests have been performed. The first major integrated test, the integrated Safety Features Actuation System (SFAS) test is scheduled to start on August 7,1986 and is expected to be completed by August 11, 1986.

Other Activities Three new reactor coolant pump (RCP) rotating elements (shaf t and impeller) are now on site. The licensee has removed interferences in containment in preparation for the pump replacement work, which will start after the integrated SFAS test is completed.

The licensee has inspected more than 500 safety related electrical connections. Approximately 600 remain to be inspected. Only twelve of the 267 Eaychem installations inspected so far were acceptable. The licensee's Raychem test program at Acton Labs (Acton, MA) should be completed this week.

The test report is scheduled to be issued August 19, 1986. The licensee's repair, replacement and engineering review of items requiring environmental qualification (EQ) is continuing. The NRC EQ inspection team is on site to complete the EQ inspection.

The licensce's inspection of 1,821 flood barrier seals protecting safety-related equipment revealed 216 seals that require repair or rework.

O The licensee is also inspecting seals in the floors of 42 rooms to insure that safety-related equipment in the rooms below are protected from water.

Miscellaneous The hearing on NRC approval of the licensee's request to bury byproduct material onsite began on August 5 and is scheduled to be completed by the end of the week.
