Response to Notice of Violation
Nuclear Regulatory Commission inspection Report 50-423/98-208
Nuclear Reaulatory Commission Citation (50-423/98-208-04)
l
l
Restatement of the Violation
Technical Specification 6.8.1.a. requires, in part, that written procedures shall be
implemented covering the activities referenced in Appendix A of Regulatory Guide 1.33,
February 1978, item 2.a., General Plant Operating Procedures, " Cold Shutdown to Hot
'
Standby." Step 4.2.34.g.2 of OP 3201, " Plant Heatup," states, IF any RCS hot or cold
,
leg WR temperature increases to greater than 195*F, DIRECT test personnel to close
1
and lock the applicable RHR outboard drain valve (3RHS*V26).
Contrary to the above, on June 2,1998, the licensee failed to direct test personnel to
close and lock RHR outboard drain valve,3RHS*V26, when RCS WR temperature
increased to greater than 195*F. Valve 3RHS*V26 was subsequently closed when
reactor coolant system wide range temperature approached 197*F during performance
of SP 3601F.4, "RCS Pressure Isolation Valve Test."
NNECo's Response
NNECo agrees with the violation.
Reason for the Violation
- The cause of the conditior is attributed to human error resulting in required actions not
being carried out as d'
.. i by the cited Operating Procedure (OP). While the
_
decision to delay the clost
af the affected valve was made on the basis that the intent
of the procedural requirement would continue to'be satisfied, the operating crew failed
to process the required temporary change to the procedure to support their decision.
Corrective Actions Taken and Results Achieved
' The lessons l' earned from this event were addressed by the Operations Manager in a
staff briefing memorandum dated June 13,1998. (AR 98010857-01)
l
At the time this violation occurred, NNECo had in place ongoing activities directed at
improving human performance in the control room. These actions were undertaken as
'
,
a result of performance deficiencies identified during the initial plant heat-up conducted
y
in preparation. for unit restart from the extended outage.
The cause of these
[
deficiencies was attributed to skill deficits which had developed during the extended
.

outage. As a consequence, NNECo reevaluated the approach to unit restart and
l
instituted additional measures to ensure an event free startup.
,
I
l
These measures included; 1) augmentation of the regular shift compliment with
additional operations department management personnel to reinforce performance
j
standards by facilitating the p!anning and execution of startup evolutions,2) providing
additional startup training to the Operations staff in advance of scheduled startup
3
1
evolutions and remedial training to address lessons learned from the specific events
'
noted during initial plant heatup, and 3) the assignment of additional management
oversight to the control room on an around-the-clock basis throughout the unit restart
and power ascension process. The result of these actions was a safe and event free
j
unit startup and power ascension program.
NNECo's Nuclear Oversight organization
subsequently concluded in its report related to the Millstone Unit 3 startup and power
ascension, that line performance had improved significantly since the Mode 4 transition
and that reduction in round-the-clock oversight coverage of control room activities was
justified.
Corrective Actions to Prevent Future Violations
The Millstone Unit 3 Operations Department currently monitors human performance
and procedure compliance related deficiencies through the Performance Anruaciator
Pane 1 Reporting System.
Within this system, key activities are monitored and
appropriate performance ' criteria are established to define corrective action thresholds.
The annunciator panels are reviewed by management to ensure that adverse
performance trends are appropriately addressed through the corrective action program.
Dah When Full Compliance Will Be Achieved
Full compliance has been achieved with respect to the condition described in this
citation.
