INSTRbMENTATION OR MORM Om BASES REACTOR TRIP SYSTEM and ENGINEERED SAFETY FEATURES ACTUATION SYSTEM INSTRUMENTATION (Continued) spray pumps start and automatic valves position, (6) containment isolation, (7) steam line isolation, (8) Turbine trip, (9) auxiliary feedwater pumps start and autoro, c valves position, (10) nuclear service water pumps start and automatic valvts peition, and (11) component cooling pumps start and automatic valves position.
The Engineered Safety Features Actuation System interlocks perform the following functions:
P-4 Reactor tripped - Actuates Turbine trip, closes main feedwater valves on T bel w Setp int, prevents the opening of the main avg feedwater valves which were closed by a Safety Injection or High Steam Generator Water Level signal, allows safety injection block so that components can be reset or tripped.
Reactor not tripped prevents manual block of Safety Injection.
P-11 Defeats the manual block of Safety Injection actuation on low pres-surizer pressure and low steam line pressure and defeats steam line isolation on negative steam line pressure rate.
Defeats the manual 1
block of the motor-driven auxiliary feedwater pumps on trip of main 1
feedwater pumps and low-low steam generator water level.
P-12 On decreasing reactor coolant loop temperature, P-12 automatically blocks steam dump and allows manual bypass of steam dump block for the cooldown valves only.
On increasing reactor coolant loop temper-ature, P-12 automatically defeats the manual bypass of the steam dump block.
I P-14 On increasing steam generator level, P-14 automatically trips all feedwater isolation valves, pumps and turbine and inhibits feedwater control valve modulation.
Surveillances for the Reactor Trip Bypass Breakers are included in response to the NRC's Generic Letter 85-09, dated May 23, 1985.
3/4.3.3 MONITORING INSTRUMENTATION 3/4.3.3.1 RADIATION MONITORING FOR PLANT OPERATIONS The OPERABILITY of the radiation monitoring instrumentation for plant operations ensures that:
(1) the associated action will be initiated when the radiation level monitored by each channel or combination thereof reaches its Setpoint, (2) the specified coincidence logic is maintained, and (3) suffi-cient redundancy is maintained to permit a channel to be out-of-service for testing or maintenance.
The radiation monitors for plant operations senses radiation levels in selected plant systems and locations and determines whet.her or not predetermined limits are being exceeded.
If they are, the signals are combined into logic matrices sensitive to combinations indicative of various accidents and abnormal conditions.
Once the required logic combination is completed, the system sends actuation signals to initiate alarms or automatic isolation action and actuation of Emergency Exhaust or Ventilation Systems.
