SUBJECT:
NRC INSPECTION REPORT 50-482/93-08 (NOTICE OF VIOLATION)
This letter refers to the inspection conducted by Mr G. A. Pick and the
inspectors identified in the attached report for the period of March 28
through May 8, 1993. The inspection included a review of activities
authorized for your Wolf Creek Generating Station.
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 examination of procedures
and representative records, interviews with personnel, and observations of
activities in progress.
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 first violation resulted from a late surveillance
test.
We are concerned with this example because of the ineffective
implementation of corrective actions developed in response to a previous
The second violation occurred because of inadequate work
instructions that failed to prevent cold stressing safety-related piping.
We
were encouraged by the self-identification by maintenance personnel on this
occasion.
The report identifies four examples of weaknesses in the implementation of
your corrective action program.
Specifically, three of these examples are
indicative of a reluctance of station personnel to initiate performance
improvement requests that identify and document conditions adverse to quality.
This issue has been previously identified and documented in NRC reports and
has been the topic of several management meetings conducted during the past
year.
We are concerned that, despite your efforts to improve your corrective
action program, station personnel are still reluctant to utilize the program
to document problems.
The fourth example concerns poor corrective actions
taken to preclude recurrence of an essential service water system waterhammer
event.
In order to fully understand the efforts that you have taken and
future initiatives that you plan to take with your corrective action program,
we request that, following the enforcement conference presently scheduled for

1 p.m. June 9,1993, Mr. Otto Maynard meet with myself and members of my staff
to discuss these issues and others concerning your corrective action program.
.
This meeting was previously discussed with Mr. Maynard.
In addition to the issues mentioned in the previous paragraph, the report
identifies two unresolved items. The first unresolved item (Section 2.2)
,
pertains to problems concerning the adequacy of procuring correct replacement
parts
This issue is of concern because it appears that weaknesses exist in
your procurement process that affects the timely completion of maintenance
conducted on safety-related systems.
The second unresolved item (Section 2.4)
relates to problems identified with timely closure of modification packages
which resulted in an instrument air system failure. This issue is of concern
because weaknesses were identified in your modification program that affect
,
the reliability of safety-related systems. These issues will remain
unresolved pending further NRC review.
Wolf Creek Nuclear Operating Corporation management personnel raised the issue
of blocking the flux doubling feature while in Modes 4 and 5.
Review by
operations management personnel resulted in the determination that the flux
doubling circuitry should not be blocked unless specific actions are taken.
This violation of Technical Specification 3.3.1, Table 3.3-1, Functional
Unit 6.b, was not cited because the criteria identified in paragraph VII.B.2
of 10 CFR Part 2, Appendix C (Enforcement Policy), were satisfied.
Additionally, personnel quickly implemented actions to prevent recurrence.
You are required to respond to this letter and should follow the instructions
specified in the enclosed Notice when preparing your response.
In your
response, you should document the specific actions taken and any additional
actions you plan to prevent recurrence. After reviewing.your response to this
Notice, including your proposed corrective actions and the results of future
inspections, NRC will determine whether further NRC enforcement action is
necessary to ensure compliance with NRC regulatory requirements.
It is our understanding that you committed to complete a review of safety-
related motor-operated valves by August 31, 1993, and to identify those valves
which require complete reassembly and a flow test to ensure maintenance was
performed correctly.
If your understanding of this commitment is different
from ours, please contact myself or Mr. Bill Johnson of my staff.
In accordance with 10 CFR Section 2.790 of the NRC's " Rules of Practice," a
copy of this letter and its enclosures will be placed in the NRC Public
Document Room.
The responses directed by this letter and the enclosed Notice are not subject
to the clearance procedures of the Office of Management and Budget as required
by the Paperwork Reduction Act of 1980, Pub. L. No. 96.511.
