Safety Parameter Display System R.
E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Lear:
An NRC letter dated April 9I 1986 requested additional information concerning isolation devices in order for the Staff to complete their review of the Safety Parameter Display System (SPDS).
The Ginna Station SPDS system utilizes field input cables that formerly terminated in the original plant process computer.
The input cables now terminate at the field multiplexers of the new system>
which are now in the same physical location as the old computer.
The isolation devices provided in the Reactor Protection System (RPS) and Engineered Safety Features Actuation System circuits were not modified during installation of the SPDS.
The existing isolation devices were reviewed by the NRC Staff during the Systematic Evaluation Program (SEP) assessment of SEP Topic VII-1.AI Isolation of Reactor Protection System from Nonsafety Systemsi Including Qualification of Isolation Devices.
The stated objective of the Staff review was to verify that the Ginna reactor has a reactor protection system design which provides effective and qualified isolation of nonsafety systems from safety systems to assure that safety systems will function as required.
The conclusion of the reviewi stated in a letter dated July 30I 1981 from Dennis M. Crutchfield to John E. Maier< was that "the Staff's position is that suitably qualified isolators have been provided at Ginna."
In order to assure that the RPS isolation devices are not subject to stresses more severe than anticipated in the original design>
the new field multiplexers are seismically qualified and utilize input cards which provide electrical isolation sufficient to prevent any credible voltage excursion from propagating to the RPS inputs from other inputs via the multiplexer itself.
All multiplexer outputs are fiber optic andi thereforei will not propagate spurious voltages from external sources.

oATE May 23 I 1986 Nr. George E. Lear SHEET NO.
The only other conducting cables terminating at the multiplexers are the 120 VAC power supplies from the Technical Support Center Uninterruptable Power Supply (TSC UPS).
These cables are routed with 120 VAC and lower voltage cables.
Breakers and fuses are also provided to protect the multiplexers in the event of electrical faults.
Thereforei this modification has'not degraded the isolation provisions reviewed and approved by the NRC Staff under the SEP program and the Staff conclusion remains valid.
Ve ruly yours, got/J/
