SUBJECT: NRC INSPECTION REPORT NO. 50-498/93-22; 50-499/93-22 (NOTICE OF

VIOLATION)

This refers to the inspection conducted by Mr Mark A. Satorius of this office

on June 28 through July 2, 1993. The inspection included a review of

activities authorized for your South Texas Project, Units 1 and 2, facility.

At the conclusion of the inspection, the findings were discussed with you and

those members of your staff identified in the enclosed report.

Areas examined during the inspection are identified in the report. Within

these areas, the inspection consisted of selective examinations of procedures

and representative records, interviews with personnel, and observations of

activities in progress. The purpose of the inspection was to determine

whether activities authorized by the license were conducted safely and in

accordance with NRC requirements.

Based on the results of this inspection, certain of your activities 2ppeared

to be in violation of NRC requirements, as specified in the enclosed Notice of

Violation (Notice). The first violation, which contains two examples and

involves an event that occurred on June 13-14, 1993, is of concern because

both licensed and nonlicensed operators were determined to have failed to

follow station procedures in the performance of their watchstanding duties.

In the first example, licensed operators conducted an inadequate shift relief

because they failed to note that spent fuel pool cooling had been lost because

component cooling water had been isolated to the in-service spent fuel pool

cooling heat exchanger. The isolated component cooling water went unnoticed

in the control roon for over 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br />, despite three indications being

available to alert operators of the abnormal condition. In the second

example, a reactor plant operator did not conduct an adequate tour of the fuel

handling building because he f ailed to notice the significant reduction in

component cooling water flow noie.es following the isolation of cooling water

to the spent fuel pool heat exchanger.

This violation is indicative of significant operator performance weaknesses.

Because of the repetitive nature of this and similar cases involving

maintenance and operator performance problems that have been documented in

recent NRC inspection reports, a management mecting has been scheduled for

July 30,-1993, to discuss your corrective actions to address these personnel i

performance problems and the actions you have taken or plan to take to -

preclude recorrence. ;

i > second violation is of concern because it involves the failure of your :

corrective action program to take actions to ensure that a condition adverse i

to quality is identified and steps taken to prevent recurrence. Specifically, ;

~

a similar event occurred during the second Unit 2 refueling outage where the

shifting of safety-related Class lE Distribution Panel DP002 from its normal ,

source of power to its secondary power source caused valves to change !

position. Following this previous occurrence, no station problem report or ;

other corrective action document was initiated to determine the root cause of :

the event. Consequently, station personnel were not fully cognizant of the !

potential plant changes that could be expected when shifting power supplies :

for safety-related Class 1E Distribution Panel DP001 on June 13, 1993. -!

i

This violation was determined to be similar to previous violations concerning

your failure to take prompt and. effective actions to correc.t problems. We

understand Houston Lighting & Power Company is already taking significant :

action to resolve weaknesses in its corrective action program as a result of

this and other NRC enforcement actions. For this reason, no response to the

Notice is required. ,

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

this letter and its enclosures will be placed in the NRC Public Document Room. -t

i

Should you have any questions concerning this inspection, we will be pleased i

to discuss them with you.

I

Sincerely,-

(
