Subject:

NRC Region I Inspection Report No. 50-309/89-08

Gentlemen:

This transmits the April B to May 17, 1989, routine inspection findings of

Mr. C. Holden, Mr. R. Freudenberger and Mr. K. Heitner, at the Maine Yankee

Atomic Power Plant, Wiscasset, Maine.

Those findings were based on observa-

tions of activities, interviews, and document reviews, and have been discussed

with Dr. Boulette of your staff.

Within the scope of this inspection, no violations were observed. Two issues

which need your attention are identified in +his report.

For one item, the

.

applicable standard for verification and validation of the microprocessor based

Primary Inventory Trend System, a meeting with our NRR staf f appears to be war-

ranted.

We understand that the second item, uncertainties in Subcooling

Margin Monitor system instrument inaccuracies, is being addressed in a proced-

bre setpoint upgrade currently in progress.

No reply to this letter is required.

Your continued cooperation with us in

this matter is appreciated.

Sincerely,

.
