APPENDIX

APPRAISAL OPEN ITEMS

1. Open Item 461/88008-01: Lack of trending capability. Three computer

systems are available-in the TSC as sources of data. These systems.are

the SR, AR/PR, and PMS/DCS systems. Of these systems, only the AR/PR

systems has any trending capability for historical data. The other

two systems do not archive data (i.e., only the current update data set

is retained it the system, and is replaced abcut every 250 milliseconds

on the next update scan). The TSC has one status board available for

the X-Y plotting of a single parameter and one matrix type status board

which can be used for the recording of parameter values versus time for

about 12 time slots.

2. Open Item 461/88008-02: The EOF HVAC system was tested during the

appraisal and the following problems were noted:

-

Procedures for activation of the HVAC system are 3 procedures

removed from the Emergency Plan Implementing Procedures (EPIPs)

making them cumbersome to locate. Activation of the E0F HVAC

is not required in the Clinton procedures until after a radiological I

airborne problem is detected in the EOF.

-

Upon test activation of the system, the normal outside air inlet i

flowpath damper (No. 242) went to the mid position instead of i

shutting as required. This failure would have allowed bypass of  !

unfiltered outside air around the HEPA filter, This problem was '

repaired prior to the inspection team leaving the site. However,.

the EOF HVAC system is presently under a generic preventive

maintenance procedure which lacks a comprehensive functional or

operational test of the system which would identify such problems.
