SUBJECT: NOTICE OF VIOLATION
l
(NRC INSPECTION REPORT NOS. 50-321/93-14 AND 50-366/93-14)
This refers to the inspection conducted by G. Wiseman of this office and the
individuals ~ identified in the enclosed report on July 26-30, 1993.
The
inspection included a review of activities authorized for your Hatch facility.
l
At the conclusion of the inspection, the findings were discussed with those
members of your staff identified in the report.
This inspection examined the implementation of the motor-operated valve (MOV)
program that you have developed to meet your commitments to Generic Letter
l
(GL) 89-10, " Safety-Related Motor-Operated Valve Testing and Surveillance."
l
The inspection consisted of interviews with personnel and selective
examination of records and procedures. Overall, the NRC is concerned that you
have NOT made sufficient progress in the implementation of your GL 89-10
program, since you have resolved only 5 of 18 concerns identified during an
inspection in February 1992 (NRC Inspection Report 50-321 and 366/92-04).
Based on the results of this inspection, certain licensed activities appeared
,
to be in violation of NRC requirements as specified in the enclosed Notice of
i
Violation (Notice). These activities involved (a) failure to evaluate data
from testing safety-related equipment to ensure that the equipment is capable
of performing its design-basis safety function, and (b) failure to take
!
l
corrective action when test data indicated the potential inability of safety-
related equipment to perform its safety function. Violation A in the Notice
is of concern because the failure to evaluate this test data on MOVs could
result in MOV inoperability not being recognized in a timely manner.
l
Violation B results from such an instance where the operability of an M0V was
questionable for over a year because of your failure to take appropriate
corrective action in response to test data from a similar M0V.
l
The NRC staff raised the concern regarding the lack of evaluation of MOV test
data during the inspection of your GL 89-10 program at Hatch in February 1992.
Although the staff did not identify any inoperable MOVs during the
February 1992 inspection and subsequent discussions, the staff emphasized the
need for you to evaluate the results of your MOV tests in a timely manner. At
the time of the July 1993 inspection, you had not developed MOV test data

evaluation procedures and had not initiated evaluations of data from MOV tests
at Hatch. The test data from the MOVs sampled by the inspectors do not
support certain important assumptions used in determining the proper sizing
i
and setting of those MOVs at Hatch that have not been tested under design-
basis conditions.
In one instance, the inspectors found that test data
i
revealed that an MOV might not have been capable of performing its design-
basis function for over a year. As a consequence of not evaluating MOV test
i
data, you have not determined if inadequacies exist in the capability of MOVs
at Hatch that were sized and set using incorrect design assumptions.
Two additional items of concern were identified during the inspection that the
staff will continue to monitor. First, your response to the notice prepared
)
by the Limitorque Corporation under 10 CFR Part 21 on the adverse effect of
i
high ambient temperature on ac motor output has been delayed in anticipation
i
of additional information from Limitorque.
Second, your consideration of the
potential for pressure locking and thermal binding of gate valves has not been
updated to reflect recent studies of these phenomena and industry experience.
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 take to prevent recurrence.
In particular, you should
provide reasons you have confidence in the operability of MOVs that have not
been dynamically tested at Hatch. After reviewing your response to this
Notice, including your proposed corrective actions and the results of future
inspections, the NRC will determine whether further NRC enforcement action is
necessary to ensure compliance with NRC regulatory requirements.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of
this letter and its enclosures will be placed in the NRC's Public Document
Room.
The response directed by this letter to the enclosed Notice is not subject to
,
the clearance procedures of the Office of Management and Budget, as required
i
by the Paperwork Reduction Action of 1980, Pub. L. no. 96.511.
Should you have any questions concerning this inspection, we will be pleased
to discuss them with you.
Sincerely,

Subject:
Hatch MOV-report
~ I have reviewed the subject report for enforcement consistency, and
.I concur.
Type and characterization of violations were similar to
Comanche Peak, demonstrating consistency. Also, they dif fered from
River Bend, where the violation was not cited because it was
identified by the licensee, also demonstrating consistency.

Request for concurrence on Hatch MOV rep
Caudle,
-
NRR and Office
of- Enforcement have
reviewed
the Hatch MOV
Inspection Report and concur with the following comments:
1. In the last sentence of the first partial paragraph on page 2 of
the cover letter, replace "your failure-to evaluate" with "not
evaluating" and replace "there might be inadequacies, of which you
are 'not aware," with "you failed to ensure that inadequacies do not
exist".
2. In the first sentence of the last large paragraph in Violation
A,
replace " requires identification of test data abnormalities
(including inadequate sizing) , but" with "is adequate because it" .
3.
In the first sentence of the second paragraph in Violation B,
replace "when the operability" with "to raise the torque switch
setting" and replace "was called into question by" "in response
to".
I will fax the markup of these pages to Pat Davenport for her use
in modifying the inspection report.
Thanks for allowing NRR and
Enforcement to review the report.
If.you have any questions,
please give me a call.
