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
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.
