1. TRIPPING THE REACTOR TRIP BREAKERS 52/RTA AND 52/RTB REDUNDANTLY DE-ENERGIZES THE ROD DRIVES.

ALL FULL LENGTH CONTROL RODS AND SHUTDOWN RODS ARE THEREBY RELEASED FOR GRAVITY INSERTION INTO THE REACTOR CORE.

2. NORMAL REACTOR OPERATION IS TO BE WITH REACTOR TRIP BREAKERS 52/RTA AND 52/RTB IN SERVICE AND BY-PASS BREAKERS 52/BYA AND 52/BYB WITHDRAWN.

DURING TEST, ONE BY-PASS BREAKER IS TO BE PUT IN SERVICE AND THEN THE RESPECTIVE REACTOR TRIP BREAKER IS OPERATED USING A SIMULATED REACTOR TRIP SIGNAL IN THE TRAIN UNDER TEST. THE REACTOR WILL NOT BE TRIPPED BY THE SIMULATED SIGNAL SINCE THE BY-PASS BREAKER IS CONTROLLED FROM THE OTHER TRAIN. ONLY ONE REACTOR TRIP BREAKER IS TO BE TESTED AT A TIME.

3. ALL CIRCUITS ON THIS SHEET ARE NOT REDUNDANT BECAUSE BOTH TRAINS ARE SHOWN.

4. OPEN/CLOSED INDICATION FOR EACH TRIP BREAKER AND EACH BYPASS BREAKER IN CONTROL ROOM.

I I I I r-0 I NOTES:

1. STEAM DUMP IS BLOCKED BY BLOCKING AIR TO THE DUMP VALVES AND VENT-ING THE DIAPHRAGMS. THE REDUNDANT LOGIC OUTPUT OPERATES TWO SOLENOID VENT VALVES IN SERIES TO REDUNDANTLY INTERLOCK THE AIR LINE BETWEEN EACH VALVE DIAPHRAGM AND ITS ASSOCIATED POSITIONER.

THE NON-REDUNDANT LOGIC OUTPUT OPERATES ONE SOLENOID VENT VALVE TO INTERLOCK THE AIR LINE BETWEEN EACH VALVE DIAPHRAGM AND ITS ASSOCIATED POSITIONER. THE SOLENOID VALVES ARE DE-ENERGIZE TO VENT CAUSING THE MAIN DUMP VALVE TO CLOSE IN FIVE SECONDS. EITHER OF THE TWO REDUNDANT BLOCK SIGNALS OR THE NON-REDUNDANT BLOCK SIGNAL WILL BLOCK STEAM DUMP INDEPENDENT OF THE OTHERS.

2. CIRCUITRY ON THIS SHEET IS NOT REDUNDANT EXCEPT WHERE INDICATED REDUNDANT.

3. SELECTOR SWITCH WITH THE FOLLOWING THREE POSITIONS:

ON - STEAM DUMP IS PERMITTED. BYPASS - T AVG INTERLOCK IS BYPASSED FOR LO-LO T AVG. SPRING RETURN TO ON POSITION OFF - STEAM DUMP IS NOT PERMITTED AND RESET T AVG BYPASS THE REDUNDANT INTERLOCK SELECTOR SWITCH CONSISTS OF TWO CONTROLS ON THE CONTROL BOARD. ONE FOR EACH TRAIN. ~. THE TWO ANALOG SIGNAL INPUTS COMING FROM TURBINE PRESSURE MUST COME FROM DIFFERENT PRESSURE TAPS TO MEET THE SINGLE FAILURE CRITERION.

5. ALL TEMPERATURE BISTABLES ON THIS SHEET AND THE TURBINE IMPULSE CHAMBER PRESSURE BISTABLE NO. PB-506C ARE "ENERGIZE TO ACTUATE".

5. LIGHTS SHOULD BE PROVIDED IN THE CONTROL ROOM FOR EACH DUMP VALVE TO INDICATE WHEN THE VALVE IS FULLY CLOSED OR FULLY OPEN

7. THE STEAML INE WHICH IS USED SIGNALS SHOWN CRITERION.

PRESSURE SIGNAL ORIGIN MUST BE DIFFERENT FOR THE STEAMLINE PRESSURE PROTECTION ON SHEET 7 TO MEET THE SINGLE FAILURE FROM THAT REV. DATE DRAWN 4 12209S JHK 1 c~~~* s~~vR A~~uA BY t@ N.E.S.

1. THESE SIGNALS INDICATE THE CLOSING OF THE STOP VALVES. POSITION DETECTION IS ACCOMPLISHED BY TWO CONTACTS PER STOP VALVE. ONE FOR EACH TRAIN. THE LOGIC SHOWN IS FOR FOUR STOP VALVES.

2. EXCEPT WHERE INDICATED OTHERWISE, REDUNDANCY IS INDICATED IN REGARDS TO @

NUCLEAR ENERGY SYSTEMS REQUIREMENTS ONLY.

3. OPEN/SHUT INDICATION IN CONTROL ROOM FOR EACH STOP VALVE.

4. THE REMOTE DISPATCHING IS TYPICAL. ACTUAL IMPLEMENTATION MAY NOT INCLUDE REMOTE DISPATCHING. REMOTE DISPATCHING IS NOT USED AT CALLAWAY.

5. GENERATOR MOTORING PROTECTION SHOULD NOT DEFEAT THE THIRTY SECOND DELAY.

6. THE REACTOR COOLANT PUMP BUS TRANSFER SHOULD BE COMPLETED WITHIN SIX CYCLES IN ORDER TO INSURE COMPATIBILITY WITH THE UNDERFREQUENCY TRIP OF THE REACTOR COOLANT PUMP CIRCUIT BREAKERS. THE TRANSFER TIME LIMIT MAY BE EXTENDED ANOTHER 4 CYCLES TO A TOTAL OF NOT GREATER THAN 10 CYCLES.

IF THE SYSTEM DYNAMICS ARE SUCH THAT A RCP TRIP DOES NOT OCCUR. THE 10 CYCLE LIMIT IS FOR PUMP MOTOR PROTECTION.

7. THE TURBINE-GENERATOR PROTECTION LOGIC IS ONLY TYPICAL OF THE ACTUAL HARDWARE DESIGN. SEE BECHTEL DRAWINGS FOR DETAILS.

8. THIS FUNCTION IS USED TO BYPASS THE REDUCED TEMPERATURE RETURN TO POWER CONTROL CIRCUITRY TO ALLOW TURBINE TESTING AND/OR TO DEFEAT THE C-16 ANNUNCIATOR SUCH AS WOULD BE REQUIRED DURING A PLANT COOLDOWN. THIS FUNCTION IS NOT USED AT CALLAWAY.

Log1c syrnbcls represent system functiOns and do not necessarily duplicate cir-cuit arrangement or dev1ces. log1c diagrams do not mherently 1mply energ1zed, de-energ1zed. or other circuit operation states. Proces~ equipmP.ott will change state when a change IS initiated, and will rem;un 111 tn1s Slate until a change to another state IS mitiated. Process eqUipment will remam 111, or return to, the original state after a loss and restoration of power, unless otherwise noted. lnl;erent equipment interlocks such as cncuit breaker trip free and reversing startmg cross mterlocks ilre not shown. Some protect1on actions are shown also as start prem1ssives. Tnp-free design prevents equipment oper at10n when a protection actiOn exists, even if a start permissive IS not prov1ded. F mal instrument setpoints are shown elsewhere. Set points shown on control logtc diagrams are approxtmate. See electncal drawmgs for details of equ1pment electncal overcurrent, short c~rcuit, and differential protection and space heaters. Tne memory, reset, and start premisstve logic associated with the operation of electncal protectiOn dev1ces 1s not shown. Electrical auxiliary system breakers are reset by operatton of the control room switch to trip. Mechanical auxthary system cucuits are reset by operation of a switch at the sw1tchgear or motor control center. T 11e test control sw1tches at the sw1tchgear which functton only when a circuit breaker IS 111 he test pos1t10n are not shown. All c~rcwt cor trois, except mterlocks with other equipment, function when a cu cutt breaker 1s 111 the test position to allow c1rcuit testing.
