ENTERGY OPERATIONS, INC. ADDITIONAL RESPONSE TO VIOLATION 9701-02
Additional Information Requested
Your response to the second violation (50-382/9701-02) was lacking, in that, the
described corrective actions were narrowly focused. Specifically, the NRC
!
inspectors reviewed 14 plant systems and the site structures monitoring program
during the Maintenance Rule Baseline Team Inspection at the Waterford-3 site. We
( identified five examples of inadequate monitoring. Our review was a sampling of the l total inventory of Waterford-3 systems, trains, and components. Your April response
letter did not address the acceptability of nonsampled systems, trains, and
components. Therefore, a potential exists that the effectiveness of maintenance on
other systems, trains, or components is not being monitored as required by the
Maintenance Rule. Consequently, your response to the violation should address the
more broader aspects of your corrective actions.
Response
in our violation response dated April 21,1997, Waterford 3 stated that provisions
would be made to monitor under 10 CFR50.65 paragraph (a)(2), the availability
performance of the broad range gas monitors, PPS, CPCs and the ESF actuation
system. The PSA would be reviewed and unavailability criteria established
accordingly. These criteria would be reviewed and approved by the Exped Panel.
'
The availability maintenance history of these systems would then be reviewed
against their respective (a)(2) unavailability performance criteria and a system
categorization made. If it is determined that (a)(1) status is warranted, then (a)(1)
goals would be established.
Our response also stated that provisions would be made to monitor under 10
l CFR50.65 paragraph (a)(2), the reliability performance of the lift function of the I
containment polar crane. The (a)(2) reliability performance criteria would be
established and approved by the Expert Panel. A reliability historical review would
l
then be performed against criteria established and system categorization made, if i
determined that (a)(1) status is warranted, then (a)(1) goals will be established.
in conjunction with above, a review of all plant systems was performed to ensure that
(a)(2) performance criteria had been established commensurate with safety. This i

. F2 age 2 of 2
review paid particular attention to areas identified in the Notice of Violation (NOV).
They are (1) the adequate establishment of unavailability performance criteria for
Risk Significant and Standby Systems down to the train and channel level and (2)
correct use of NUMARC 93-01 scoping criteria for all systems (both scoped and non
scoped) to ensure that all appropriate systems and functions have been included in
the Maintenance Rule program.
As a result of this review, two (2) additional systems where unavailability was not
appropriately monitored were identified. The systems are the starting air system for
the Emergency Diesel Generators (EDG) and Excore Nuclear Instrumentation (ENI).
These 2 systems are in addition to those previously identified in the NOV.
For each ot G.e 2 systems above, the PSA will be reviewed and unavailability criteria
established accordingly. These criteria will be reviewed and approved by the Expert
Panel. The availability maintenance history of these systems will then be reviewed
against their respective (a)(2) unavailability performance criteria and a system
categorization made. If it is determined that (a)(1) status is warranted, then (a)(1)
goals will be established.
The additional actions addressed above will be completed by August 30,1997.
Upon completion of the above, Waterford 3 will be in full compliance.
