Operations Summary June 1985 The following summary describes the significant operation activities during the reporting period.

In support of this summary, a chronological log of significant events is included in this report.

There were five reportable occurrences and no revisions to previous occurrences reported to the NRC during the month of June.

Unit 1 The unit was in cold shutdown the entire month for the unit's end-of-cycle 6 refueling outage.

Unit 2 The unit was in cold shutdown the entire month for the unit's end-of-cycle 5 refueling outage.

Unit 3 The unit was in cold shutdown the entire month on an administrative hold to resolve various TVA and NRC concerns.

Prepared principally by B. L. Porter.

3 Operations Summary (Continued)

June 1985 Refueling Information Unit 1 Unit I was in shutdown for its sixth refueling on June 1,1985 with a scheduled restart date of March 31, 1986. This refueling will involve loading 8x8R (retrofit) fuel assemblies into the core, replacing recirculation piping, work on "A" and "B" low-pressure turbine, upgrade hangers and anchors, and environmentally qualify instrumentations. The unit was shut down on March 19, 198$, and remained in cold shutdown until June 1,1985, because of unfinished modifications to meet environmental concerns.

There are 764 assemblies in the reactor vessel. The spent fuel storage pool presently contains 252 EOC-5 assemblies, 260 EOC-4 assemblies; 232 EOC-3 assemblies; 156 EOC-2 assemblies; and 168 EOC-1 assemblies. The present fuel pool capacity is 3,471 locations.

Unit 2 Unit 2 was shut down for its fifth refueling outage on September 15, 1984 with a scheduled restart date of December 15, 1985. This refueling outage will involve loading additional 8X8R (retrofit) assemblies into the core, finishing torus modification, turbine inspection, piping inspection, TMI-2 modifications; post-accident sampling facility tie-ins, core spray change-out, and feedwater sparger inspection.

There are no assemblies in the reactor veseal. At month end, there were 273 new assemblies, 764 EOC-5 assemblies, 248 EOC-4 assemblies 352 EOC-3 assemblies, 156 EOC-2 assemblies, and 132 EOC-1 assemblies in the spent fuel storage pool. The present available capacity of the spent fuel pool is 77 locations. All old racks have been removed from the pool and new HDR's are being installed.

4 Operations Summary (Continued)

June 1985 Unit 3 Unit 3 is scheduled for its sixth refueling outage approximately November 30, 1985, with a scheduled restart date of November 10, 1986. This refueling involves loading 8X8R (retrofit) assemblies into the core, and complete reinspection of stainless steel piping. The unit was shutdcwn on March 9, 1985, and will remain in cold shutdown until August 28, 1985, on an administrative hold to resolve various TVA and NRC concerns.

There are 764 assemblies presently in the reactor vessel. There are 248 EOC-5 assemblies, 280 EOC-4 assemblies,124 EOC-3 assemblies,144 EOC-2 assemblies, and 208 EOC-1 assemblies in the spent fuel storage pool. The present available capacit/ of the spent fuel pool is 914 locations.

4 24 OUTAGE MAINTENANCE & MAJOR MODIFICATION MANAGEMENT June 1985 MAJOR WORK COMPLETED A.

Unit 1 1.

'the official refueling outage start date is June 17, 1985. As of June 30, the drywell head was removed and preparations were underway to detension the reactor vessel head. The modification to ensure seismic integrity of the crane during vessel head lift with the first five inches _of travel has been deferred until reassembly of unit 2.

2.

Disassembly, rotor removal and decontamination of "B" low pressure (LP) spindle will start after main steam line plugs are seated. Work completed includes partial layout to support removal, sandblast and inspection of the spindle.

B.

Unit 2 1

Repairs to the "A" jet pump instrument lines were completed, vessel head and internals were removed, and the cavity floodup was completed on June 17, 1985.

2.

Turbine Floor - The lifting beam was transported to unit 1 floor to support disassembly of 1B LP turbine.

3 Drywell/ Torus - The torus paint compactor demobilized on June 5, 1985. Overlay of GR-2-15 was performed between June to and 17.

Followup inspection indicated a flow which will require reworking the weld. Weld DSRHR-SA was evaluated as unacceptable and. will require repair.

4.

Balance-of-Plant - Limited condenser work. The Condenser Circulat-ing l

Water system was closed up to prepare for hypochlorite treatment.

Unit 2 (Continued) 5.

Valves - No significant work was completed.

"B" I/B Main Steam Isolation Valve (MSIV) and both "C" MSIV's will require disassembly and rework due to vendor error.

6.

Major Modifications - Electrical modifications progress was significantly restricted by lack of Quality Control (QC) inspector coverage due to prioritization of this coverage on unit 3 Machanical

~

modifications' progress was more severely impacted due to direct impact on engineering and craft efforts, as well as the forementioned problem with QC inspector coverage.

a.

ECN P0392 (SCRAM Discharge Header Modifications): Vent lines installation is in progress and electrical work i,s 40%

complete.

Schedule slip reflects projected impact of unit 3 short outage on i

unit 2 work.

b.

The increased duration of the unit 2 outage will require Inte-l grated Leak Rate Testing (ILRT) during this outage in lieu of the cycle 6 outage. The increased duration will also require l

additional Local Leak Rate Test (LLRT) of most previously tested

~

valves due to Appendix "J" testing periodicity requirements.
