DOCKET NO. 50-445 AND 50-446 SAFETY CHILLED WATER CHILLER UNITS SDAR: CP-86-18 (INTERIM REPORT)

Gentlemen:

On May 21, 1986, our letter logged TXX-4820 provided notification that the issue involving difficulties in starting and operating the safety chilled water chiller units was reportable under the provisions of 10CFR50.55(e).

The issue identifies the failure of the Component Cooling Water (CCW) supply to maintain temperatures'at or above the chilled water return temperature for both the operating and standby chillers. Our last interim report was logged TXX-6323, dated March 9, 1987.

All analyses and modifications for Units 1 and 2 are being evaulated.

We expect to submit our next report no later than May 3, 1988.

Very truly yours,

h. b.
