SUBJECT: NRC INSPECTION REPORT NO. 50-445/99-03; 50-446/99-03

Dear Mr. Terry:

This refers to the inspection conducted on January 24 through March 6,1999, at the Comanche

Peak Steam Electric Station, Units 1 and 2, facility. The enclosed report presents the results of

this inspection.

^

During the 6-week period covered by this inspection, your conduct of activities was generally

characterized by r3fety-conscious operations, sound engineering and maintenance, and careful

radiological won etutrols. However, our review of your operability evaluation regarding motor-

operated valvet P., 'osed that you failed to include important information about degraded

emergency core cooling system performance that may impact your ability to perform bot-leg

recirculation following a loss-of-coolant accident. Your procedures for controlling operability

evaluations do not include a formal process for ensuring that known degraded conditions are

considered. We will be examining this closer in a future inspection.

In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and its

enclosure will be placed in the NRC Public Document Room (PDR).

Should you have any questions concerning this inspection, we will be pleased to discuss them

with you.

Sincerely,

seph I. Tapia, hief
