THE HPCI SYS IS ARRANGED FOR TEST OF PUMP AT FULL FLOW AND ALL VALVES FOR OPEN AND CLOSE CAPACITY AT ANY TIME EXCEPT WHEN INITIATION SIGNAL OR AUTO ISOLATION SIGNAL JS ACTIVATED. IN EVENT THE INITlATION SIGNAL OCCURS WHILE TEST IS UNDERWAY THE SYS AUTOMATICALLY RETURNS TO START-UP MODE.

ALL POWER FOR OPERATION OF DC VALVE MOTORS SHALL ORIGINATE FROM A PLANT DC BUS. POWER FOR AC OPERATED VALVES SHALL ORIGINATE FROM ANY EMERGENCY AC BUS.

ALL PART NO'S PREFIXED BY 23 UNLESS OTHERWISE SHOWN.

AUXILIARY RELAYS & DEVICES NOT SHOWN ON FUNCTIONAL CONTROL DIAGRAMS EXCEPT WHERE REQUIRED TO CLARIFY FUNCTION.

FIVE IDENTICAL SETS OF STEAM LEAK DETECTORS COMPRISE CHANNEL A, WITH ONLY ONE SET BEING SHOWN FOR CLARITY. CHANNELS B, C, & D SHALL BE CONNECTED THE SAME WAY WITH EACH CHANNEL GIVING AN INDEPENDENT ISOLATION CLOSURE SIGNAL TO CHANNELS "A" AND "B". THREE STEAM LEAK DETECTOR SETS PER CHANNEL SERVF. HPCI EQUIPMENT AND ITS STEAM PIPING, WITH THE REMAINING MONITORING THE STEAM PIPING SERVING RHR.

OPERATION OF HIGH STEAM FLOW SWITCHES DPIS-76 & 77 ARE DELAYED 3 SECONDS BY TDR-K33 & K45.

10.

RHR STEAM CONDENSING IS NO LONGER AN OPERATIONAL MODE.

11. ACTUATION OF CHANNEL "A" CLOSES M023-15, A023-70, A023-71, AND PRODUCES TURBINE TRIP.

ACTUATION OF CHANNEL "B" CLOSES M023-16, M023-5B, A023-70, A023-71 AND PRODUCES TURBINE TRIP.
