Attention:
Mr. W. F.
Conway
Executive Vice President,
Nuclear
Gentlemen:
Subject:
NRC Inspection of Palo
Verde Units 1,
2 and
3
This refers to the inspection
conducted
by Messrs.
D. Coe, J. Ringwald
and J,
Sloan from December 2, 1990, through January 5, 1991, of
activities authorized
by
NRC License
Nos.
and NPF-74,
and
to the discussion of our findings held by the inspectors
with members of
the Arizona Public Service
Company staff at the conclusion of the
'nspection.
Areas
examined during this inspection
are described in the enclosed
inspection report.
Within these
areas,
the inspection consisted of
selective
examinations of procedures
and representative
records,
interviews with personnel,
and observations
by the inspectors.
Based
on the results of this inspection, it appears
that one of your
evolutions
was not conducted in full compliance with NRC requirements,
as
set forth in the Notice of Violation, enclosed
herewith
as Appendix A.
The violation is associated
with a Unit evolution performed
on December-.6,
1990,
when the Reactor Coolant System
was
inadvertently diluted while placing
an ion exchanger
in service.
Your
own Incident Investigation Report identified that weaknesses
in crew
performance,
procedures,
and communications all contributed to this
situation.
While the violation meets
the criteria in Section
V.G. of the
NRC Enforcement Policy for not being cited,
we consider it appropriate to
issue
a violation to highlight the weaknesses
evident during the evolution
and the missed opportunities to prevent or mitigate the
dilution.'n
addition to your response
to the enclosed
Notice, we request that you
address
the weaknesses
noted in Paragraph
7 of this report,
beyond the
procedural
inadequacy that the Notice cites.
Your response
to this Notice is to be submitted in accordance
with the
provisions of 10 CFR Part 2.201
as stated in the Notice of Violation.
In accordance
with 10 CFR Part 2.790(a),
a copy of this letter and the
enclosure will be placed in the
NRC Public Document
Room.
The response
directed
by this letter and the accompanying
Notice are not
subject to the clearance
procedure of the Office of Management
and Budget
as required
by the Paperwork Reduction Act of 1980,
PL 96-511.
