. . . 1 Operations Summary June 1982 4

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 16 reportable occurrences and one revision to previous reportable occurrences reported to the NRC during the month of June.

Unit 1 There was one scram on the unit during the month. On June 24, the reactor scrammed in order to repair the inlet pipe to a feedwater heater after the pipe split due to steam errosion.

Unit 2 There were no scrams on the unit during the month, i Unit 1 There was one scram on the unit during the month. On June 5, the reactor scrammed after the turbine tripped when a 250-VDC supply was reenergized after a fuse was replaced and several relays did not sequence correctly.

SUMMARY

June 1982 GENERAL Major work which was completed during this reporting period is as follows: (1) dewatering pump (P0252) commitment was met, but material problems are still hindering the completion of the automatic controls; (2) moved cardreaders on diesel-generator doors (PO465); (3) prefabricated debris screens (PO428); (4) completed assembly of one rotating element for the reactor feedpump work next outage; (5) completed instrumentation and heater work on condensate tanks (P0238); (6) EPA modifications (P0472 and PO480); (7) rerouted cables for torus temporary power supply except for routing that requires the outage to be in progress; (8) prefabrication of vacuum breaker tees (P0093); and (9) the replacement of the unit 3 turbine building overhead crane wheels.

ELECTRICAL The major work that is continuing through this report period is: (1)

LPCI modifications (L1845) - fabricating and installing conduit 90s, conduit brackets, conduit support hangers and conduit on unit 2 elevations 621 and 639 is in progress; (2) L2052 automatic backwash system for RCW strainers units 1, 2, and 3 -installing brackets, conduit, and junction boxes. Pulling cable on unit 2. Completions unit 1 - 44 percent, unit -

44 percent, and unit 3 - 10 percent; (3) update CCTV System (P0287) -

pulling and splicing cables. Making terminations in CAS and SAS; (4) illuminate exterior of the protected area (P0286).- installation of the diesel-generator control wiring. Mounted transformers on lighting poles; (5) emersency lighting (PO479) - mounting lighting brackets in unit 1

SUMMARY

June 1982 ELECTRICAL (Continued) reactor building (approximately 57-percent complete) and mounting brackets in unit 1 turbine building and control bay; (6) Inspection and tagging of conduit in reactor, diesel generator, and control bay buildings in all units (WP 5560) - inspection and tagging in unit 1 elevation 565 is approximately 75-percent complete; and (7) other electrical work, wrfting work plans for the unit 2 cycle 4 refueling outage, providing temporary classroom facilities in the hypochlorite building for operations, support work, electrical inspections of cords, tools, and lights and telephone maintenance.

MECHANICAL The major work activities in progress are: (1) the fabrication of the strongbacks for unit 1 and 2 is nearly complete with a few welds to be verified; (2) installation of piping and drain valve for radwaste (P0178) -

delayed due to material problems; (3) prefabrication of the "N" and "M" line MSRV tailpipes is approximately 95-percent complete; (4) anubber inspections and snubber rebuild are approximately 80-percent complete; and (5) other mechanical work includes: Quadrex has completed the decontamination of one spent fuel rack, fabrication of a segregated - - - - -

stainless-steel work area, fabrication of welding test stations, hanger inspections (IEB 79-14 and 79-02), and instrument sensing line inspections (MMI-118).

SUMMARY

June 1982 TORUS Unit 2 torus prefabrication and selected external modifications continue in preparation for the upcoming cycle 4 outage.

(1) Tie downs - All MK IIs have been set and leveled, except number 22.

Anchor bolts have been pulled-tested for MK I. This completes the tie-down work until the unit is shut down.

(2) Temporary ECCS supports - Completion of permanent ECCS supports number 1 percent, 4 percent, 5 percent, 8 percent, 9 -

15-percent, 13 percent, and 16 - 100-percent completed. Work has not started on number 12. ,

(3) External ring girder reinforcing - numbers 1, 4, 5, 8, 9, 13, and 16 are 100-percent complete.

(4) Torus snubbers - wall brackets are in transit to the site. The work plan for installation is in the approval cycle.

(5) Quencher end-arms prefabrication - work is completed.

(6) J, L, and N gussets: prefabrication was completed. Installation of "J" is 95-percent, "N" is 97-percent, and "L" is 100-percent complete.
