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.
T. Polich,
D. Coe,
C.
Myers,
and
P. ()ualls,
on June
12 through August 6, 1989, 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 Nuclear
Power Project staff at the conclusion of the inspection.
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 several
of your
activities were not conducted
in full compliance with NRC requirements,
as set forth in the Notice of Violation, enclosed
herewith
as Appendix A.
Paragraph
11 of the enclosed
inspection report discusses
a long standing
problem with the operation of the Unit 2 pressurizer
spray valves,
which
contributed to
a safety injection actuation following the July 12,
1989
Unit 2 reactor trip.
Our review determined that the problem with the
spray valves
has
a lengthy documented history, however, the issue
has
only recently
been raised to upper management's
attention.
As we have
discussed
with you during recent
NRC/ANPP management
meetings,
we are
concerned that other issues
of long duration
may exist which have not
received
an appropriate
level of attention.
We encourage
you to take
whatever actions
are necessary
to ensure that
known plant problems are
being promptly and completely acted
on.
Following the July 12,
1987 reactor trip, portions of the non safety
related
main feedwater
(MFW) system
were inadvertently overpressurized.
In discussions
with you and your staff,
we have frequently expressed
the
importance of stopping
when faced with uncertainty,
and the importance of
conducting engineering
work in a rigorous,
documented,
and controlled
manner.
Therefore
we were disappointed
to conclude that the actions
taken
by your engineering staff to evaluate
the overpressurization
condition were hurried, poorly documented initially, and
based
on
erroneous
assumptions.
This is further discussed
in paragraph
12 of the
enclosed report.

Paragraph
14 of the enclosed
inspection report discusses
the setting of
an Atmospheric
Dump Valve nitrogen pressure
regulator in accordance
with
verbal
vendor instructions contrary to component technical
manual
requirements.
This resulted
in the improper setting
and subsequent
malfunction of the regulator.
We are concerned
about your lack of
controls in the performance of safety-related
maintenance
on important
plant components.
In your response
to the attached
please
discuss
the specific quality controls you are implementing to
preclude
recurrence
of the cited problem.
Your response
to the enclosed
Notice is to be submitted in accordance
with the provisions of 10 CFR 2.201
as stated
in Appendix A, Notice of
Violation.
In accordance
with 10 CFR 2.790(a),
a copy of this letter and the
enclosures 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.
Should you have
any questions
concerning this inspection,
we will be
pleased
to discuss
them with you.
Sincerely,
