Dear Mr. Conway:
SUBJECT:
NRC TEAM INSPECTION OF EMERGENCY OPERATING PROCEDURES,
REPORT NOS. 50-528/92-12, 50-529/92-12 AND 50-530/92-12
This report transmits the findings of the NRC team inspection conducted at the Palo Verde
Nuclear Generating Station from April6 through April 10, 1992. The purpose of the inspection
was to evaluate the new revision of the Palo Verde Emergency Operating Procedures
(EOPs).
At the conclusion of the inspection, the preliminary findings were discussed with you and those
members of your staff identified in the enclosed report.
, Arizona Public Service has devoted extensive resources
to revise and improve the Emergency
Operating Procedures
used at Palo Verde. The team determined that the operators would be able
to utilize the new EOPs to mitigate emergency conditions.
The new procedures are scheduled
for implementation later this year.
You have made substantial progress in correcting problems
previously identified through 'an intensive upgrade
program
involving a multi-disciplined
approach and development of a comprehensive writers'uide.
While we see clear evidence., of increased commitment to the procedure development process;
the team also identified several weaknesses
requiring your attention, prior to implementation of
the new procedures.
We are concerned
that many of the problems identified during this
inspection had also been identified during the last EOP inspection.
We consider that your staff
would have identified most of the issues ifa more aggressive verification and validation program
was in place.
Significant. problems identified include:
(1) an inadequate isolation strategy for
a loss of coolant accident outside of containment; (2) conflicting information among the EOPs
when confronted with a steam generator tube rupture in one steam generator coincident with an
excess steam demand event in the other steam generator; (3) incomplete information in the EOPs
when adverse
containment conditions exist; (4) inconsistent application of standard

actions with regard to verification of safety functions; (5) conflicting direction given to the
operators*with respect to procedural adherence
when in the EOPs; and (6) weaknesses
in the
quality organization's
involvement
as part of the EOP development
process.
It is our
understanding
that the first five items identified above will be corrected
prior to. your
implementation of the EOPs.
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.
