NRC INSPECTION REPORT NOS. 50-528,529,530/93-48
This refers to the inspection conducted by J. Sloan, H. Freeman, J. Kramer,
and A. MacDougall, of this office, and T. Alley, of the Department of Energy,
,
'
on November 2 through December 6, 1993. The inspection included a review of
activities authorized for your Palo Verde facility. At the conclusion of the
inspection, the findings were discussed with those members of your staff
identified in the enclosed report.
Areas examined during the inspection are identified in the report. Within
these areas, the inspection consisted of selective examinations of procedures
and representative records, interviews with personnel, and observation of
activities in progress.
Based on the results of this inspection, certain of your activities appeared
'l
to be in violation of NRC requirements, as specified in the enclosed Notice of
i
Violation (Notice) and enclosed inspection report. The violations involved
i
two instances of the failure of licensed operators to follow operating
procedures. Although the violation involving the operator's failure to
adequately monitor the reactor coolant system draindown evolution meets the
criteria in the NRC Enforcement Policy for enforcement discretion, it is being
.;
cited to emphasize the importance of maintaining close operational control
during reactor coolant system inventory changes. The inspection also
identified two non-cited violations involving the operator's failure (1) to
independently verify a valve's position after its position was changed, and
(2) to verify the operability of alternate power sources when a emergency
diesel generator was taken out of service. We are concerned that each of
these violations (both cited and non-cited) involve. the failure to control or
complete operator actions during plant evolutions or changes to plant
configuration. Additional management attention may be needed to ensure that
operational controls are adequately implemented.
The inspection also identified a third non-cited violation involving the
failure to verify that a control element assembly was properly latched before
lifting the upper guide structure from the Unit I reactor vessel. We commend
you for the scope and aggressiveness of your investigation and subsequent
corrective actions following this event.
