50-259 50-260 50-296 BROWNS FERRY NUCLEAR PLANT (BFN) NRC INSPECTION REPORT 50-259, 50-260, 50-296/92-21 REPLY TO NOTICE OF VIOLATION (NOV)
This letter provides TVA's reply to the NOV transmitted by letter from B. A. Wilson to M. 0. Medford on July 2, 1992.
NRC cited TVA with a violation for failure to control Measuring and Test Equipment (M&TE).
TVA shares the staff's concern on this issue because of the potential adverse effect that nonconforming test equipment could have on safety related equipment and agrees with the staff that the problems identified in the NOV were indicative of insufficient management oversight in the control of M&TE.
Accordingly, TVA initiated immediate corrective actions to rectify both, the programmatic issues and the specific examples.
TVA con'siders that these actions (discussed subsequently in Enclosure
TVA agrees that the examples noted in the NOV violated regulatory requirements.
Enclosure 1 to this letter provides TVA's "Reply to the Notice of Violation" (10 CFR 2.201).
Enclosure 2 to this letter provides a listing of a TVA commitment made in the response to the NOV.

Reply to Notice of Violation (NOV)
Inspection Report Number "During the Nuclear Regulatory Commission (NRC) inspection conducted on May 16-June 16,,1992, a violation of NRC requirements was identified.
In, accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violation is listed
'below:
10 CFR 50, Appendix B, Criterion XII requires that measures shall be established to assure that tools,
- gauges, instruments, and other measuring and testing devices used in activities affecting quality are properly controlled, calibrated, and adjusted to maintain accuracy within specified limits.
t Nuclear Quality Assurance (NQA) Plan, Section 9.5.2.B.3 implements these requirements and establishes methods to identify previous usage of Measuring and Testing Equipment, (M&TE) found to be in nonconformance.
Site Standard Practice 6.7, Control of Measuring and Test Equipment implements the NQA Plan requirement, and states that activities associated with M&TE found to be nonconforming shall be investigated and
,dispositioned for each use subsequent to the previous calibration.
Contrary to,the above, these requirements were not met for dispositioning the following three examples of M&TE Nonconformance
- Packages, concerning previous usage of suspect equipment.
1.
- Seven packages out of 14 did not contain documentation of investigating all previous uses of M&TE.
For example package 91-00486.1, completed January 14, 1992, for an out of tolerance flowmeter transducer assembly listed ten previous uses of the instrument, but only one was documented as dispositioned.
The other
- uses, including surveillances on critical systems, structures, and components, (CSSC), required by Technical Specifications, were not investigated.
Package 91-00332.1 listed work order 90-23710 on the usage log, however work order 90-23718 was actually investigated.
2.
Package 91-00504.1, generated due to an out of tolerance multimeter, was completed on February 10,
- 1992, 29 days past the required 30 day time limit.
Five other packages, 91-00486.1, 92-00002.1, 91-00355.1, 91-00355.3, and 91-00175.1, all of which were used to perform surveillances and maintenance on CSSC, were also late.
0'
' Package 91-00355.3, for a defective digital caliper used on CSSC, documented a two week period to be investigated rather than the entire period since the last calibration which covered a seven month period.
This is a Severity Level IV Violation (Supplement I) applicable to all three units."
The reason for the violation was insufficient management oversight.
As a result, an approved site procedure was not being properly implemented.
Contributing to this condition was the fragmentation of responsibilities for the M&TE program among several different; groups at BFN.
20 t v t
v In order to correct the fragmentation of responsibilities, TVA has assigned overall responsibility for the M&TE program to a manager in the Instrument Maintenance section.
Among this manager's duties is the responsibility for providing the Plant Manager with a monthly status report on the Out-of-Tolerance (OOT) program.
The first report was provided to the Plant Manager on July 10, 1992.
In addition to the organizational realignment,- TVA has made other changes to the M&TE program to address the findings corresponding to the three examples noted by the NRC staff.
These changes are described below.
The reason that certain METE nonconformance packages did not contain documentation on previous uses was the ineffective processing of the documentation.
Specifically, M&TE 00T documentation was sent to various site groups for review.
In turn, some groups copied the documentation and redistributed it to many evaluators.
During this redistribution, administrative errors were made and accountability for the M&TE usage was lost.
In order to evaluate the adequacy of previous M&TE uses, TVA will review by September,30,
- 1992, OOT investigations completed since January 22, 1992 (when fragmented reviews started).
This evaluation will ensure that each usage for the noted seven packages will be investigated.
0
In order to prevent recurrence of this problem, each section has assigned a M&TE coordinator as a single point of contact to track OOT review packages.
The coordinators are responsible for ensuring that M&TE evaluations are logged in and out, each usage is properly
- reviewed, QA requirements are maintained, and evaluation due dates are met.
Additionally, the coordinator is responsible for ensuring that a complete'OOT review package is submitted back to the M&TE Group.
The late OOT reviews noted by the staff were the result of an ineffective manual tracking system.
In order to prevent recurrence of this problem, OOTs are now tracked in a computer tracking system.
This system identifies, any OOT packages approaching the 30-day time limit to ensure the 30-day time limit is not exceeded without prior'anagement approval.
The reason package 91-00355.3 was not reviewed for the entire calibration period was that the checkout logs only documented the use during the noted two-week period.
- However, TVA acknowledges that the reviewed pages may not have been inclusive since the pages were not paginated or clearly identified.
In order to prevent recurrence start date and start statement accountability of the complete Additionally, the new checkout pages are accounted for.

This review will be completed by September 30, 1992.
Full compliance will be achieved by September 30, 1992.
