SUBJECT:
NRC 'INSPECTION REPGRT NO. 50-528/99-11; 50-529/99-11; 50-530/99-11
Dear Mr. Overbeck:
This refers to the inspection conducted on June 14 through July 2, 1999, at the Palo Verde
Nuclear Generating Station, Units 1, 2, and 3, facility. Additional review and inspection were
performed in the Region IVOffice until September
1, 1999. Supplemental onsite inspection
was also conducted August 30 through September 2, 1999. This inspection assessed
your
containment spray system, 125Vdc power system, and portions of your containment isolation
systems for conformance to applicable regulatory requirements for the Palo Verde Nuclear
Generating Station. The enclosed report presents the results of this inspection.
Atthe end of the first onsite period of the inspection, the team leader conducted an exit meeting
with you and members of your staff on July 2, 1999. Following this exit meeting, your staff
provided the inspection team with additional requested information. New information was
provided to the team in several telephonic conferences and during the supplemental onsite
inspection. This'new information changed some of the preliminary findings discussed
in the exit
meeting, necessitating a followup exit meeting that was conducted via teleconference on
September 30, 1999.
Overall, we concluded that the containment spray and 125Vdc systems conformed to their
design and licensing bases and were capable of performing their intended safety functions.
However, we identified numerous errors in design calculations, procedures, and the Updated
Safety Analysis Report. While none of these errors Individuallyconstituted operability
problems, the number of issues revealed problems in the implementation of your design control
program which, under different circumstances,
may have been more significant. Examples of
problems identified by the team included:
(1) improper assumptions,
references, and input
associated with design calculations; (2) inconsistencies among the Updated Final Safety
Analysis Report, design basis calculations, setpoints, and the installed configuration; and (3)
failure to translate changes to design basis calculations, drawings, and procedures.
Some of
these errors appeared to have been caused by a lack of a fullyeffective process for identifying
the interrelationship between calculations.
The team identified several examples in which your engineering staff failed to follow
through'ompletely
with changes to desigh basis calculations resulting from changes in the source
calculations or other inputs. One potential cause of this failure is the practice of relying on

engineering judgement to determine whether the individual significance of a change warrants
an update to the affected calculations.
While such changes may be minor, the collective
impact, which because of your current practices may not be recognized by your staff, could
result in unintended or unacceptable degradations.
Accordingly, we stress that revising design
basis calculations to reflect changes and modifications, regardless of the impact of each
individual change, is an essential element in the maintenance of your plant's design basis.
We,
therefore, encourage you to review your policies, processes,
and practices to ensure that the .
plant's design basis and licensing basis is appropriately maintained.
Based on the results of this inspection, the NRC has determined that violations of NRC
requirements occurred, all of which are being treated as noncited violations, consistent with
Appendix C of the Enforcement Policy. The noncited violations are described in the subject
inspection report.
If you contest any of the violations or severity level of the noncited violations,
you should provide a response within 30 days of the date of this inspection report, with the
basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk,
Washington, DC 20555-0001, with copies to the Regional Administrator, Region IV; the
Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington,
DC 20555-0001; and the NRC Resident Inspector at the Palo Verde Nuclear Generating
Station.,
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and its
enclosure willbe placed in the NRC Public Document Room.
Should you have any questions concerning this inspection, we will be pleased to discuss them
with you.
Sincerely,
