Gentlemen:

Subject: NRC Inspection Nos. 50-317/85-15. 50-318/85-13

This transmits the June 18 - August 15, 1985, resident inspection findings by

Messrs. T. Foley and D. Trimble at the Calvert Cliffs Nuclear Power Plant, Lusby,

Maryland. Those findings were based on observation of activities, interviews,

independent measurements, and document reviews, and have been discussed with

Mr. Russell of your staff.

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

This report includes observations of licensee performance in response to occur-

rences which rendered a Main Steam Isolation Valve inoperable and the subsequent

test program which ensued to determine the cause of the valve's inoperability.

Your performance with respect to this issue was in consonance with NRC's philosophy

of determining the " root cause" of equipment failure. These observations may be

reflected as positive attributes of licensee performance as part of the Systematic

Assessment of Licensee Performance (SALP) process.

Your cooperation with us is appreciated.

Sincerely, DiC21 Signed Byr;
