- Ooerations SunniLcI Hay 1983 The following summary describes the significant operation activities during the reporting period. In support of this summary, a chmnological log of significant events is included in this report.

There were 19 reportable occurrences and no revisions to previous reportable occurrences reported to the NRC during the month of May.

Unit 1 .

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

Unit 2 There was one scram on the unit during the month. On May 30, the reactor was manually scrammed to repair a control air leak in the drywell. The unit had been in a controlled shutdown until the decision was made to scram the unit to expedite maintenance activities.

Unit ~4 There was one scram on the unit during the month. On May 28, the reactor scrammed on low reactor vessel water level when a low-pressure feedwater heater string isolated while another low-pressure feedwater heater string was isolated for maintenance, causing the reactor feedwater pumps to trip on low suction pressure.

MAJOR WORK AREAS A. Refuel Floor - On May 2,1983, core unload was completed and the critical path work continued with LPRM changeout, which was completed on May 4, followed by fuel pool gate installation on same day at 2300 hours0.0266 days <br />0.639 hours <br />0.0038 weeks <br />8.7515e-4 months <br />.

Control roc drive (CRD) uncoupling started on May 6 and was completed on May 13. After initial tryout and learning, the new uncoupling tool for unlatching CRDs from top proved itself very effective and reduced exposure rates greatly. In parallel with unlatching, the rod position indication system (RPIS) probes were removed in preparation for CRD changeout. The first CRD was changed out on May 10. A total of 100 were scheduled for changeout, and at the end of May were completed.

Fuel sipping started on May 17, and on May 31, 615 bundles were completed out of 764.

B. Turbine - During May, all components that required disassembly were disassembled. Radiation levels on the low-pressure turbine "A" and "B" inner cylinders was high, and the turbine decontamination room was required to decontaminate the inner cylinders. One inner cylinder has been deconned. In addition to the inner cylinder, the "B" and "D" control valves have been sent to turbine decontamination due to radiation levels.

B. Turbine - (Continued)

All sandblasting was completed in May.

The inspection of the "B" rotor revealed that the. blades from the 13th stage turbine end would require removal and shipment to the General Electric Service Shop in New-York for repair. Currently, methods are being reviewed for deconning blades to an acceptable level for

. shipment into the state of' New York. It was also discovered that low-pressure "A" rotors 13th stage blades would require repair, but this repair can be accomplished onsite. At this writing, no definite i schedule has been developed to access the schedule impact of these I repairs due to lack of sufficient scheduler-type information.

May 1983 MAJOR WORK AREAS (Continued)

B. Turbine - (Continued)

An inspection of the front standard revealed that the bull gear, turbine oil pump gear and bearing had acquired damage. Paperwork is in process to award a contract for repair.

The "B" and "D" control valve maintenance will continue upon completion of deconning the valves.

C. Drywell - During the first week in May, all 13 main steam relier valves (MSRV) were removed and blanks installed, started preparatory work for installation of snubbers at Yarway column, and prefabrication of MSRV control air piping. Fabrication of vacuum breaker parts started and one was completed and assembed on May 19 for testing at Wyle Laboratories; however, extremely slow progress in getting contracts issued to Wyle Lab prevented shipment of both MSRVs and vacuum breakers.

Main steam isolation valve work consisted of further testing, and by the end of May, seven out of eight were found to require rebuild; four were disassembled and lapping started on valveseats after long and extensive decontamination work, which had not been expected.

D. Electrical - During the month of May, most of the electrical work plans were issued for review and approval. All of the work plans that require significant manpower and duration were released for work during May except for P0126. The most significant work items are l'isted below:

1. P0399 Long Term Solution to Instrument and Control Bus Problems -

All the conduit has been installed, and the associated equipment has been installed except for one disconnect switch which cannot be installed until an outage is available on the "Tr bus. In addition, a procedure was written which identifies the steps required to perform the tie-ins to the "A" and "B" bus.

Currently, operations is reviewing the tie-in procedure.

2. PO422 Provide Redundant Class IE Protection at Interface of Non-l class IE Power Supplies and the RPS percent of the conduit

SUMMARY

May 1983 MAJOR WORK AREAS (Continued)

E. Mechanical - By mid-May drawings were received for duct work at diesel generators. By the end of May, virtually all overhead duct supports were installed; 80-percent of ducting for one unit was prefabricated by Power Service Shops, when material delivery problems shutdown duct p'refabrication.

ISI work on recirculating system rapidly increased from 29 welds to 61; requiring inspection, of which 15 were completed in May with seven rejects and two under evaluation.

Probolog contractor moved onsite on May 9 and started work on heat exchangers; completing stator, hydrogen, exciter, EHC, and portions of the turbine lubrication oil coolers by month end.

ANI Requirements - P0392 Scram Discharge Header prefabrication and its flush connections on P0538 required ANI involvement; also P0361, torus attached piping and nozzle reinforcing. Hold points have been established in work plans. Maintenance items under Section XI during the mor.th of May did not require any welding work.
