.j, REQUEST FOR ADDITIONAL INFORMATION i.
CONCERNING THE CRYSTAL RIVER UNIT 3 SAFETY PARAMETER DISPLAY SYSTEM i
Each operating reactor shall be provided with a Safety Parameter Display System (SPDS). The Comission approved requirements for an SPDS are defined in NUREG-0737, Supplenient 1.
In the Regional workshops on Ceneric Letter 82-33
}
held during March 1983, the NRC discussed these requirements and the staff's h
review of the SPDS.
The staff reviewed the SPDS safety analysis a'nd supplemental documents provided by Florida Power Corporation (Reference 1). The staff was unable to complete the review because of insufficient information. The following additional in-1 formation is required to continue and complete the review:
j f
INSTRUMENTATION AND CONTROL SYSTEMS BRANCH
!sokationDevices Provide the following:
I a.
For the type of device used to accomplish electrical isolation, describe ib the specific testing perfonned to demonstrate that the' device is accept-l
{
ableforitsapplication(s). This description should include elementary
)
diagrams when necessary to indicate the test configuration and how the maximum credible faults were applied to the devices.
u 5
j....
2 b.
Data to verify that the maximum credible faults applied during the test were the maximum voltage / current to which the device could be exposed,
(
and define how the maximum voltage / current was determined.
Data to verify that the maximum credible fault was applied to the output c.
ofthedeviceinthetransversemode(betweensignal.andreturn)and
. other faults were considered (f.o., open and short circuits).
d.
Define the pass / fail acceptance criteria for each type of device.
Provide a commitment that the isolation devices comply with the environ-e.
f ment qualifications (10CFR 50.49) and with the seismic. qualifications which were the basis for plant licensing.
f.
Provide a description of the measures taken to protect the safety systems from electrical interference (i.e., Electrostatic Coupling, EMI, Common Mode and Crosstalk) that may be generated by the SPOS.
