4 The following additional infomation is required to continue and complete i
the review:
Isolation Devices Please provide the following:
a.
For the type of device used to accomplish electrical isolation, describe the specific testing perfomed to demonstrate that the device is acceptable for its application (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.
b.
Data to verify that the maximum credible faults applied during the test were the maximum voltage / current to which the device i
could be exposed, and define how the maximum voltage / current was detemined.
Data to verify that the maximum credible fault was applied to c.
theoutputofthedeviceinthetransversemode(betweensignal and return) and other faults were considered (i.e., open and shortcircuits).
d.
Define the pass / fall acceptance criteria for each type of device.
Provide a connitment that the isolation devices comply with the e.
environment qualifications (10 CFR 50.49) and with the seismic qualifications which were the basis for plant licensing.
