SUMMARY

OF OPERATING EXPERIENCE OPERATION:

The plant began the month at reduced power coastdown as required to reach the refueling date. The plant shutdown on 4-11-80 for the Cycle 2-3 refueling.

The fuel movement began on 4-24-80.

The spent fuel examination program discovered two fuel assemblies (D38 and C18) that sustained extensive fuel damage to a single rod in each assembly.

l The fuel rod damaged was located at the third pin position in from the corner and was immediately facing the outside core baffle plate joint.

It is speculated that the internals baffle plate joint gaps are slightly open permitting water-jet impingement on a single fuel rod of certain perimeter assemblies.

3 MAJOR SAFETY-RELATED MAINTENANCE:

Work continued on improvement modifications to the Plant Security and Fire Protection Systems.

Work began on the removal for analysis of 29 steam generator D Row 1 tubes.

1 Work began on Inservice Inspection of Class 1, 2 and 3 equipment.

Work began on Local Leak Rate Testing.

I

)

Work continued on radiographic examination of feedwater lines for cracks.

Work continued or. modification of piping systems restraints and supports.

Work began on several TMI-related design modifications (RV head vent, RV water level, containment water level, post LOCA environment electrical equipment assessment, safe shutdown remote instrumentation and decouple switches, separate power supply to steam PORV and AFWP pressure instrument).

Work continued on masonry wall inspection, review and repair.

Work began on MSIV inspection and investigation.

LICENSE CHANGES:

Amendment #43, LCR-TNP-80-02, LCA-59; Changed temporarily the surveillance interval associated with control rod drop testing to permit an extension of two days.

MISCELLANEOUS:

Small amounts of tremors and volcanic activity continued at Mt. St. Helens sporatically throughout the month.

Though no lava has been discharged, local mountain deformations and tremors ranging up to 4.5 Richter have occurred. No plant seismic movements have been measured.

The ASLB hearings on the Control Building seismic modifications recommenced on 4-16-80 and concluded on 4-17-80.

The NRC Staff agrees with PCE's analysis of the adequacy of the proposed modifications.

Turbine-generator high pressure cell inspection and CV overhaul began.
