Dear Sir:
Generic Letter 89-06 Safety Parameter Display System Generic Letter 89-06 requested licensees to certify that either their Safety Parameter Display System (SPDS) fully met the requirements of NUREG 0737, Supplement 1. " Requirements for Emergency Response Capability", as clarified by NUREG 1342, "A Status Report Regarding Industry Implementation of Safety Parameter Display Systems", or that the SPDS would be modified to fully meet these requirements.
PGE provided the results of the review of NUREG 0737, Supplement 1 in a letter to the NRC dated August 15, 1989.
PGE's review of NUREG 1342 is now l
complete. PGE complies with all of the criteria listed in NUREG 1342 except Item III.C.1, " Isolation from Safety Systems". The following list of presently used isolation devices are not listed in NUREG 1342:
P0XBORO:
N-2AI-12V, INPUT COMPONENT CURRENT ISOLATED N-2AI-T2V, INPUT COMPONENT TC AND mV N-2AO-VAI, CUSTOM OUTPUT COMPONENT 4 TO 20 mA 8909190165 69091r, DR ADOcg or,000344 FDC

o Portland General ElectricCompany Document Control Desk September 15, 1989 Pare 2 These isolation devices have been previously evaluated by the NRC Staff.
In the Safety Evaluation Report for the Trojan SPDS issued by the NRC on June 13, 1985, the Staff concluded that the isolaters used were acceptable I
for interfacing the SPDS with safety systems.
Therefore, PCE does not intend to make any modifications to the SPDS.
Sincerely, b
