ENFORCEMENT CONFERENCE SUMMARY
!
i
l
On July 1,1987, representatives of Georgia Power Company (GPC) met with the
l
,
1
NRC at the NRC's request at the Vogtle site near Waynesboro, Georgia. The main
'
topics of discussion were Technical Specification (TS) compliance regarding the
residual heat removal (RHR) operability, reactor trip breaker (RTB) operabi-
!
lity, and the Trans Delaval Inc. (TDI) diesel generator (DG) operability.
j
i
GPC positions regarding these violations are presented in Enclosure 2.
The
j
security issue addressed in this Enclosure will be discussed in separate
j
l
correspondence.
'
The information presented by GPC basically confirmed the violations regarding
the RHR and RTB compliance.
New information on how GPC interprets the DG
license condition and TS Action Statements was received. Since NRC represen-
l
tatives consider your approach to be a conservative interpretation, the
Violation as indicated as 50-424/87-37-03 " Failure to Follow TS 3.8.1.1 Actions
.
i
Regarding the Activities Which Render the Diesel Inoperable" is closed and
Unresolved Item 50-424/87-45-01 " Resolve License Condition and DG Action
Statement Compliance" is open. The purpose for the Unresolved Item will allow
the staff to determine the appropriate course of action.
The current staff
position is that footnotes are part of the Action Statement and since one
i
footnote requires the test to be completed regardless of when the diesel is
returned to service, the licensee remains in the Action Statement while in full
compliance with the LCO. The second footnote then requires that the diesel not
be rendered inoperable when pursuant to the Action Statement.
Your position
being that, while one footnote requires a test only after full LCO compliance
j
is achieved, this is not part of the Action Statement and thus the second
q
footnote does not apply to the diesel.
The NRC, when developing the TDI TS,
however did not consider your approach.
'
i
Regarding the RTB, the NRC disagrees with your position that you were in
compliance with Action 13 of TS 3.3.1.
We also note that your interpretat on
provided to the Shift Personnel limits the time-to perform maintenance to less
than two hours until the issue is resolved. Action to resolve the issue rests
soley with your corporate and site organization issuing the correct clarifica-
tion.
Since the event occurred on June 2 and the interim interpretation was
not issued until June 21, the NRC is concerned with your staff's ability to
achieve prompt corrective action to prevent recurrence.
The NRC is presently considering enforcement action of the RHR and RTB issues.
This meeting served to enhance Region II's understanding of the issues.
