Docket Nos. 50-498 and 50-499 i

P. O. Box 1700 Houston, Texas 77251

SUBJECT:

RELIEF REQUEST FOR TESTING OF REACTOR HEAD VENT VALVES, SOUTH i

TEXAS. PROJECT, UNITS 1 AND 2 (TAC NOS. 75174 AND 75175)

By letter dated October 19, 1989 (ST-HL-AE-3245), Houston Lighting & Power Company (HL&P) requested relief from the requirement to test the reactor head vent valves at quarterly intervals.

Instead, HL&P proposed that the valves be exercised each cold shutdown not to exceed once every three mcnths.

After considering the request, we have concluded that a relief request is not required.

In particular IWV 3412(a) of Section XI of the ASHE code permits fullstrokeexercisingofvalvesduringcoldshutdownifsuchtestingisnot practical during plant operation. Documentation of the change to your Inservice Testing Program may be done through the use of a " cold shutdown justification" which will then become part of the program.

We plan no further action on your request of October 19, 1989.

Sincerely, OriginalSigncd Dy Gcotsc F.D!ck,Jr.
