REPLY TO NOTICE OF VIOLATION
NRC Inspection Report 98-04 describes a violation where Nonh Atlantic did not take action to
promptly determine the status of the A and D steam generator steam pressure protection
channels. North Atlantic's response to this violation is presented below.
s.
1.
Description of the Violation:
'
The following is a restatement of the violation:
10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, states, in part, that measures shall
be implemented to ensure that conditions adverse to quality are promptly identified.
l
l
l
Contrary to the above, on May 4,1998, NAESCO did not take action to promptly identify
l
whether steam pressure protection channels for the A and D steam generators were operable,
!
after three of the six steam pressure protection channels for the B and C steam generators were
found to be inoperable. Subsequent testing determined that two of the six A and D steam
generator pressure protection channels v'ere inoperable.
This is a Severity Level IV Violation (Supplement 1).
2.
Reply to the Notice of Violation:
Reason for the Violation
North Atlantic agrees with the violation. On April 27, 1998, North Atlantic commenced
calib' ration activities for six (three each on the B and C steam generators) steam generator
l
pressure protection channels. On May 1,1998, the lead / lag value for three channels were found
l
outside of the acceptability limits specified in the calibration procedures. The three channels
were calibrated and returned to service. On May 4,1998, North Atlantic determined that the
lead / lag values addressed in the calibration procedures were Technical Specification allowable
values and, as such, the as-found data was outside the Technical Specification limits.
l
An Adverse Condition Report (ACR) was initiated and the event was determined to require a
l
License Event Report (LER) pursuant to 10CFR50.73(a)(2)(i) due to the operation of the plant
-
from May 1,1998 to May 4,1998 in a condition prohibited by the Technical Specifications.
l
North Atlantic submitted LER 98-005-00 on May 29,1998.
-
On May 1,1998, Station management requested Maintenance personnel to investigate the
applicability of this condition on the A and D steam generators. This was not acted upon
-
l
promptly. Additionally, the individuals involved in the preparation and review of the ACR did
not recognize that the out of tolerance condition identified on the B and C steam generators
should have called into question the adequacy of similar channel calibrations performed on the A
and D steam generators. By May 4,1998, North Atlantic had not pursued the validation of the
i
status of similar channels on the A and D steam generators in a timely manner. In addition,

i
when the ACR was discussed during the daily Station meeting on May 5,1998, insufficient
l
information was presented regarding the potential for the condition to be common to the other
'
steam generators and as a result the operability of the A and D steam generators was not pursued'
>
promptly.
!
!
This event was included in the scope of a comprehensivbreview of lead / lag issues. North
Atlantic performed a thorough review of the calibration methodologies used to determine NLL
!
card time constants. This review was proactive and involved forming an event team, consulting
l
with vendors and bench top testing.
The cause of this event is that the Corrective Action System was not effectively implemented
,
after the initiation of the ACR. There was not adequate communication between the departments
'
regarding the specifics of the channel calibration failures and the potential for common failures -
l
was not adequately questioned / pursued. As a result, action was not promptly initiated to validate
,
the status of the A and D steam generators in a timely manner.
l
!
Corrective Actions
!
1. The individuals involved in initiating and reviewing this Adverse Condition Report have
l
been coached and counseled.
!
Date When Comoliance Will Be Achieved
i
!
North Atlantic is currently in compliance with 10 CFR 50 Appendix B, Criterion XVI
" Corrective Action."
