AGENDA - REMOTE MULTIPLEXING SYSTEM APPLICATION TO WNP-2 (1) Provide a complete list of components (pumps, valves) whose actuation, interlock, or status indication is dependent on the proper operation of each 1-E multiplexer.

(2) For the components cited above, describe means of remote or local control (other than cutting wires or jumpering) which may be employed should the multiplexer fail.

(3) Describe the multiplexer pre-operational test program.

(4) Describe test and/or hardware features employed to demonstrate fault tolerance to electro-magnetic interference.

(5) Describe interconnection, if any, of the 1-E multiplexer to non-lE devices such as the plant computer.

(6) Describe on-line test and/or diagnostic features which may be employed including operator alarms / indicators and their location (7) Describe the multiplexer power source (s).

(8) Describe the dynamic response to momentary interruption of A/C power.

(9) Describe the applicability of the current proposed plant technical specifications to the 1-E multiplexers.

(101 Describe hardware architecture of the unit field multiplexer, central control unit, and control room multiplexer.

(11) Describe firmware architecture.
