(. EMERGENCY OPERATING PROCEDURE EOP-15.0 ANTICIPATED TRANSIENTS WITHOUT TRIP (HEWT) 1.0 Purpose This procedure provides guidelines for operator action in the event a reactor trip and/or turbine trip does not occur following an automatic trip signal.

2.0 Symptoms 2.1 Failure to obtain a reactor trip following an automatic reactor trip signal.

2.2 Failure to obtain a turbine trip following an automatic turbine trip signal.

3.0 Automatic Actions None 4.0 Immediate Operator Actions j-(' 4.1 If a reactor trip does not occur following an automatic reactor trip signal then:

4.1.1 Attempt to manually trip the reactor from the Main Control Board. If not successful, then: ,

l 4.1.2 Momemtarily de-energize load center 2D l and 2E.

CAUTION Load centers 2D and 2E should be re-energized immediately and all necessary loads should be restarted.

4.2 If a turbine trip has not occurred following an automat c turbine trip signal, 4.2.1 Attempt to manually trip the turbine from the Main Control Board. If the turbine does not trip, then:

4.2.2 De-energize the E.H. Pumps 2A & 2B from the Main Control Board. Start all available auxiliary feed pumps and throttle as necessary to maintain S/G

{ level in the narrow range. If a turbine trip has not occurred, then:

( 5.0 Subsequent Ooerator Actions 5.1 If a reactor trip is not forthcoming after immediate action, then:

Go to local panel and manually open and rack out Reactor trip breakers and Reactor trip bypass breaker and flush the Boron Injection Tank to the Primary System as follows:

5.1.1 Stop the BIT Recirc Pumps 2A & 2B.

5.1.2 Close BIT Recirc Pmps to BIT Iso Vlv CVC-HV-8942.  :

5.1.3 Close BIT to BIT Recirc Pump Iso CVC-HV-8945A and CVC-HV-8945B.  !

5.1.4 Open Boron Injection Tank outlet valves CVC-MOV-8801A and CVC-MOV-8801B.

5.1.5 Open Boron Injection Tank inlet iso CVC-MOV-8803A and CVC-MOV-8803B.

5.2 If following an automatic turbine trip signal,

,l i.

the turbine does not trip and causes an'-uncontrolled cooldown, emergency borate in accordance with  :

EOP-6.0.  !

l 5.3 When a reactor trip does occur, refer to EOP-5.0.

5.4 When a turbine trip does occur, refer to AOP-3.0.

5.5 If a safety injection signal occurs, refer to EOP-0. .
