9/1/81 COMPLETED BY:

W. O. Nicholson TELEPHONE:

503/556-3713 Ext. 293 SUtOfARY OF OPERATING EXPERIENCE OPERATION:

The plant began the montn operating at approximately 80% power at the request of the load dispatcher.

Full power operation was achieved on August 4, 1981.

On August 9, 1981, a circulating water pump trip resulted in a Turbine trip /

l Reactor trip. The unit was back on-line within five hours. On August 10, 1981,

}

an identical plant trip occurred when the same circulating water pump tripped while croubleshooting-The unit was back on-line ir three hours.

Power was reduced to approximatery 64% on August 9).,

1931, to replacc the coupling end bearing on the notth main feedwater pamp turbine. The work was completed and power eased co 100% on August 22, 1981.

For the remainder of the month, the plant operated at or near full power.

Occasional small power reductions due to high condenser back pressure were required on seven days during the month due to hot weather.

The Reactor Coolant System gross gamma activity increased from about 5 uC/ml to about 10 pC/ml in the first half of August.

Since this time, RCS activity has remained essentially constant.

Radiochemistry analysis shoue suspected fue2 failure in 8 to 12 rods in the twice burned fuel region.

MAJOR SAFETY RELATED MAINTENANCE:

The work was completed on structural modification of the Control and Auxiliary Building walls to improve seismic integrity.

The work was completed on the revision of the Auxfliary Feedwater turbine steam admission valves from AC motor-operated to air-operated.

Fire hydrant #4 was relocated and tested satisfactorily.

The work continued on the Reactor Vessel Level Indicating System outside of Containment.

The work was completed on the Containment Water Level Monitoring System and tested satisfactorily.

MISCELLANEOUS MAINTENANCE:

Annual preventativa maintenance was comp) i on the east emergency dieael generator.

SUMMARY

OF OPERATING EXPERIENCE (Cont.)

f LICENSE CHANGES:

Amendment 65 - Revises the program for periodic inspection of the Control Building connection bolts.

Amendment 66 - Makes administrative changas related to off-site and on-site functional organizational charts, minimum shift crew composition, correction j

of a typographical error, membership of.the off-site review committee, and i

clarifies responsibilities of the on-site review committee.

Amendment 67 - Deletes licensa conditions related to interim operation of the facility and to the Control Building modification program. Updates the design features section of the Technical Specifications to describe the modified structure.

i MI'SCELLANEOUS :

'The work is continuing on the Technical Support Center.

i.

The electric Auxi' ury Feedwater Pump discharge was cross-connected with the discharge of both tho turbine driven and diesel driven Auxiliary Feedwater 2

Pumps.
