Dear Mr. Hunter:
Attached please find test plan and preliminary test report for Safety Parameter Display System isolation (SPDS). This letter also provides the action taken in regard to the information needed for staff review discussed in Reference 3, Item 7.C. and 7.D.
NRC requested "With regard to isolation devices between the SPDS and n
safety systems, provide the following information:"

..1 Item 7.C.
For each type of device used to accomplish electrical isolation, describe the specific testing performed to demonstrate that the device is acceptable fcr its application (s). This description should include the test configuration and how the maximum credible faults were applied to the devices.
ITEM 7.D.
Data to verify that the maximum credible fault was applied to the output of the device in the transverse mode (between signal and return) and other faults were considered (i.e. open and short circuits).
Item 7.C.
is addressed by Attachments 1 and 2 to this letter.
Item 7.D. is addressed by Attachments 3 thru 7.
If you have any questions regarding this matter, please call Mr.
