SUBJECT:
NJTICE OF VIOLATION
(NW INSPECTION REP 3RT NOS. 50-327/92-36 AND 50-328/92-36)
This refers to *.he routine resident inspection conducted by W. Holland of this
office from November 29, 1992, to January 2, 1993. The inspection included a
review of activities authorized for your Sequoyah facility.
At the conclusion
of the inspection, the indings were discussed with those members of your
staff identified in the anclosed inspection 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 observation of
activities in progress.
Based on the results of the inspection, an apparent violation was identified
and is being considered for escalated enforcement action in accordance with
the " General Statement of Policy and Procedure for NRC Enforcement Actions"
(Enforcement Policy), 10 CFR Part 2, Appendix C, (1992).
The apparent
violation involved inadequate procedures and failure to follow procedures,
which resulted in the mispositioning of throttle valves. These problems
resulted in 3 lack of configuration control which potentially had a
significant effect on the ability of safety-related systems to perform their
intended safety function. Accordingly, no Notice of Violation is presently
being issued for these inspection findings.
Please be advised that the number
and characterization of the apparent violation described in the enclosed
inspection report may change as a result of further NRC review.
An enforcement conference to discuss this apparent violation has been
scheduled for January 26, 1993, in the NRC Region 11 Office.
The purposes of
this conference are to discuss the apparent violation, its cause and safety
significance; to provide you the opportunity to po' int out any errors in our
inspection report; to provide an opportunity for you to present your proposed
corrective actions; and to discuss any other information that will help us
determine the appropriate enforcement action in accordance with the
Enforcement Policy. You will be advised by separate correspondence of the
results of our de'iberations on this matter.
No response regarding the
apparent violation is required at this time.

_JAN 15 1993 -
In- additio'n,' based on the results of the inspection, certain of your -
activities appeared to violate NRC requirements as described in the enclosed
Notice of Violation (Notico). We are concerned about the violations because-
they: indicate a recurring problem at Sequoyah in the area of configuration
control of safety related equipment. The mispositioning of a diesel generator
fuel oil transfer pump handswitch, the mispositioning of a Refueling Water
,
' Storage Tank immersion _ heater handswitch, and mispositioned throttle valves
are examples of problems -in configuration' control which affected safety
_
related plant equipment.
In addition, an unresolved Item was also identified
_,
in this inspection Report associated with potential problems in planning,
'
s
coordination, and configuration control of infrequently performed operational.
,
l
activities.
This issue is still being reviewed by the NRC.
Several problems
l:
in configuration control ef safety related equipment have also been documented
l
in previous Inspection Reports. Although the root causes of the above.
problems are in some cases varied, a recurring outcome appears to be the
inability of Sequoyah management to insure the proner alignment of safety
related equipment and maintain proper configuration during operationil
l
!
activities. The Sequoyah management staff has initiated long term corrective
4
'
,
l
actions to address these problems.
The result of these activities will be
carefully reviewed during future NRC inspections.
An additional activity which appeared to be-in violation of NRC requirements
as described in the enclosed Notice was associated with the failure to perform
inservice inspection (ISI) activities in accordance with lechnical-
Specifications. We are concerned about this violation because it reflects a -
lack of ownership with regard to the ISI pressure testing program.
Previous
programmatic weaknesses have been identified in your ISI program regarding.aL
lack of management direction and control,
l
i
In accordance with .St:ction 2.790(a) of the NRC's " Rules of Practice," a copy
of this letter and its enclosures will be placed in the NRC's Public Document
