Subject:
NRC Inspection of Palo Verde Units 1,

k
This refers to the inspection
conducted
by Messrs.'.
Coe, J.
Ringwald
and J.
Sloan,
from September
30 through
November 3, 1990, of activities
authorized
by NRC License
Nos.
and to'he
discussion of our findings held by the inspectors with members of the
Arizona Public Service
Company 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<epresentative
records,
interviews with personnel,
and observation
s by the inspectors.
Based
on the results of this inspection, 't appears that one of your
activities
was not conducted
in full comp iance with NRC requirements,
as
set forth in the Notice of Violation, encl
sed herewith as Appendix A.
Our concern over the apparent
deficiencies<'in the retest
procedures for
certain safety-related
valves is heightened
by the extended
time and
extensive
NRC inspector
involvement required .to attain
a thorough review
'of this area.
In addition, recent errors discovered, by youl staff in the database
affecting the Core Operating Limits Supervisory
System
(COLSS)
calculations
are of concern in that it appears
your staff failed to
thoroughly address
discrepancies
in the database
identified by the vendor
several
months prior to your recognition of the errors.
We note that you
have initiated an investigation into the root cause of these
and previous
errors.
Although the safety significance of each of these errors
was
small, they appear to reflect a potential
programmatic
problem in the
control of computer data.
We arill review your evaluation
and corrective
actions in future inspections.
Your response to this Notice is to be submitted in accordance
with the
provisions of 10 CFR Part 2.201
as stated in Appendix A, Notice of
Violation.
~ ..e. In accordance
with 10 CFR Part 2.790(a),
a copy of this letter and the
<~ enclosures will'e placed in the
NRC Public Document
Room.
