Mr. B. Ralph Sylvia
Executive Vice President - Nuclear
Niagara Mohawk Power Corporation

Syracuse, New York 13212
Dear Mr. Sylvia:
Subject:
NRC Region I Combined Inspection Report No. 50-220/92-24 and
50-410/92-28
This refers
to the results of the routine resident
safety inspection
conducted
by Messrs.
W. Schmidt and W. Mattingly from September 27 through October 31, 1992, at Nine MilePoint
Units 1 and 2, Scriba, New York. Mr. Schmidt discussed the inspection findings with members
of your staff at the exit meeting conducted on November 13, 1992.
This inspection was directed toward areas important to public health and safety.
The enclosed
NRC Region I Inspection Report describes the areas examined during the inspection.
Within
these areas,
the inspection consisted of observation of activities in progress,
interviews with
personnel,
and selective examinations of procedures and representative
records.
F
Your staff operated both units safely. However, in two instances senior reactor operators at Unit
1 did not take correct actions following: an instance of not having the proper shift manning in
the control room; and when unanticipated
half-scrams were generated,
multiple times during
surveillance testing.
The failure to have a senior reactor operator in the control room for five
minutes was by itself not safety significant.
We are concerned because this was not identified
to station management until five days after it occurred.
The lack of adequate shift manning as
required by plant technical specifications is an apparent violation and is being considered for
escalated enforcement, in accordance with the "General Statement of Policy and Procedures for
NRC Enforcement
Actions (Enforcement
Policy),
10 CFR Part 2, Appendix C (1992).
Accordingly, no Notice of Violation is presently being issued for this inspection finding.

Further,
du
g th
performance of surveillance
testing of the reactor protective
system
instrumentation,
a
senior
reactor
operator
failed to reconcile
procedure
problems
and
unanticipated half-scram conditions before continuing with the procedure.
This issue is a concern
because itshows a continuing lack ofunderstanding by operators ofexpectations for stopping and
reviewing evolutions where unexpected events occur. This is in violation ofNRC requirements,
as specified in the enclosed Notice of Violation.
With respect to the potential escalated enforcement action discussed above, you willbe contacted
under separate
correspondence.
Based on the results of this inspection, you are required to
respond to this letter and should follow the instructions relative to the Notice when preparing
your response.
In'your response,
you should document the specific actions taken and any
additional action you plan to prevent recurrence of these types ofissues.
Further, please include
in your response
a discussion of the actions
you have taken or plan to take to address
the
attention-to-detail concerns and configuration control issues discussed in this inspection report.
Your cooperation with us is appreciated.
Sincerely,
