SUBJECT:
NRC INSPECTION REPORT NO. 50-498/93-21; 50-499/93-21 (NOTICE OF
VIOLATION)
'
This refers to the inspection conducted by Mr. J. 1. Tapia of this office on
May 10 through June 10, 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 appeared
,
'
to be in violation of NRC requirements, as specified in the enclosed Notice of
Violation (Notice).
The violation is of concern because it involved the
-
f ailure to ensure that the seismic qualification of the Qualified Display
Processing System (QDPS) was maintained by taking prompt and effective
corrective action to evaluate the effect of missing fasteners identified in
i
the card cages and power supply racks.
This condition, originally identified
-
by your system engineer on January 4, 1993, did not receive an evaluation for
system operability until April 29, 1993, after identification of the condition
by a member of the NRC Diagnostic Evaluation Team.
Your operability
evaluation subsequently determined that two Technical Specification governed
safety-related components, the Steam Generator Power Operated Relief Valves
1
and the Reactor Coolant System Subcooling Monitor, should have.been declared
inoperable as a result of these missing fasteners.
Thus, your failure to take
adequate corrective action resulted in potential violations of Technical
.
Specifications 3.7.1.6 and Technical Specification 3.3.3.6.

r
This violation was determined to be similar to previous violations concerning
(
your failure to take prompt and effective actions to correct problems. We
!
understand HL&P is already taking significant action to resolve weaknesses in
!
its corrective action program as a result of this and other significant
l
enforcement actions.
For this reason, no response to the Notice is required.
'
In addition to the violation, a previously identified unresolved item was
reviewed.
This unresolved item involved the operation of both units in
apparent violation of various Technical Specifications. - These conditions
,
resulted from errors in the methodology for adjusting the trip settings on
molded case circuit breakers and are of concern because inadequate maintenance
instructions resulted in 12 breakers, and subsequently the Technical
!
Specification governed motor-operated valves that were powered from these
breakers being considered inoperable.
At the end of this inspection an
engineering evaluation was being performed by your staff to determine if the
!
adjustments made to these circuit breakers were acceptable and the motor-
operated valves were operable.
This issue will remain unresolved pending
i
further NRC review.
l
l
In accordance with 10 CFR Section 2.790 of the NRC's " Rules of Practice," a
j
copy of this letter and its enclosures will be placed in the NRC Public-
!
Document Room.
Should you have any questions concerning this inspection, we will be pleased
{
to discuss them with you.
Sincerely,
)
