I. SET-POINT FOR UNDERVOLTAGE RELAYS SHOULD BE APPROX. 70%. THE MAXIMUM ALLOWABLE DETECTOR TIME DELAY <WITH THE ADJUSTABLE DELAY SET TO ZEROl BETWEEN REACHING THE SETPOINT VALUE AND PASSING ON THE SIGNAL TO THE REACTOR TRIP CIRCUITRY SHOULD NOT EXCEED 0.2 SEC.

2. REACTOR COOLANT PUMPS I & 2 ARE ON BUS I.

REACTOR COOLANT PUMPS 3 & 4 ARE ON BUS 2.

3. THE SETPOINT OF THE UNDERFREQUENCY RELAYS SHOULD BE ADJUSTABLE BETWEEN 52 CPS AND 59 CPS.

THE MAXIMUM ALLOWABLE DETECTOR TIME DELAY < INCLUDING THE ADJUSTABLE DELAY) BETWEEN REACHING THE SET-POINT VALUE ANO PASSING ON THE SIGNAL TO THE TRIP CIRCUITS SHOULD NOT EXCEED APPROX. 0. I SEC.

4. THE MAXIMUM ALLOWABLE TIME DELAY BETWEEN THE TIME THE RCP BREAKERS RECEIVE A TRIP SIGNAL AND THE TIME THE BREAKERS HAVE TRIPPED AND PASSED ON THE OPEN SIGNAL TO THE REACTOR TRIP LOGIC SHOULD NOT EXCEED 0. I SEC.
5. SHEET NUMBERS REFER TO THE REFERENCE NUMBERS BELOW.
6. WHENEVER A PROCESS SIGNAL IS USED FOR CONTROL AND IS DERIVED FROM A PROTECTION CHANNEL, ISOLATION MUST BE PROVIDED.
7. THIS DRAWING ILLUSTRATES THE FUNCTIONAL REQUIREMENTS OF THE REACTOR CONTROL AND PROTECTION SYSTEM. THIS DRAWING DOES NOT REPRESENT ACTUAL HARDWARE IMPLEMENTATION.

FOR HARDWARE IMPLEMENTATION, REFER TO THE APPLICABLE SCHEMATIC.
