Attention:

Genticuien:
SUBJECT: HRC INSPECTION REPORT NO. 50-528/529/530/92-41
Thi:, refers to the inspection conducted by J. Sloan,11. Freeman, D. Kirsch, F.
Ringwald, and T. Sundsmo of this office, on November 3 through December 14,
1992.
The inspection included a review of activities authorized for your Palo
Verde facility.
At the conclusion of the inspection, the findings were
discussed with thnse members of your staff identifit,d in the enclosed t eport.
Areas examined during the inspection are identified in the report. Within
these areas, the inspection consisted of selective exaninations of procedures
and representative records, interviews with personnel, and observation af-
.
activities in progress.
Your attention is directed to paragraph 7 of the enclosed report which
discusses a reactor trip at Unit-1 caused by the failure-of a protective relay
associated with the main generator.
This event is of concern in that vendor
iMormation was previously available indicating that the relay which failed
should have been modified to correct known problems. Additionally, it
appeared that the relay vendor was contacted.only after NRC questioning
prompted the action.
You are encouraged to ensure that vendo,' information is
--
,
adequately controlled and assessed.
Two non-cited violations were identified during this- inspection. The first
dealt with a technician performing an independent verification of a valys
'
position in a tanner that did not meet your expectations.
The second ins *,ance
involved the rem 9 val of a circuit breaker from its cuo'cle without a
maintenance ~ order ta control the work.
Both violations were not cited because
-
of your corrective actions and the relatively low safety significance of the
occurrences.
