Docket Nos. 50-498 and 50-499 Mr. William Cottle Group Vice-President, Nuclear Houston Lighting & Power Company Post Office Box 1700 Houston, Texas 77251

SUBJECT:

SUPPLEMENTAL SAFETY EVALUATION OF HOUSTON LIGHTING AND POWER COMPANY'S RESPONSES REGARDING OPERATOR ACTION TIMES DURING A STEAM GENERATOR TUBE RUPTURE (SGTR) AT SOUTH TEXAS UNITS 1 AND 2 (TAC NOS. M75099 AND M75100)

The staff's safety evaluation (SE) dated April 20, 1992, indicated that Houston Lighting and Power Company's (HL&P) response to confirmatory issue 1 (NRC letter of March 30,1987) was incomplete because operator respctse times were obtained for three operating crews rather than for all operating crews.

This issue was retained as an open item.

By letter dated December 16, 1992, HL&P submitted demonstrated operator response times representing all of the South Texas Units 1 and 2 operators.

The staff has evaluated HL&P's response to the open item.

We find that HL&P has satisfactorily responded to the open item identified in the staff's SE dated April 20, 1992. The results of the staff's review are contained in the enclosed supplemental safety evaluation. This completes our review activities under TAC Nos. M75099 and M75100.

Sincerely, Original Signed By Lawrence E. Kokajko, Senior Project Manager Project Directorate IV-2 Division of Reactor Projects III/IV/V Office of Nuclear Reactor Regulation
