EMERGENCY -INSTRUCTION EI-I-4.3 REACTOR TRIP 1.0 PURPOSE 1.1 *A reactor triJ?\is initiated automatically by the Reactor Protection System if unsafe operating conditions are
- approached. It~ay also be initiated manually from the
. control console., This instruction provides the actions required to ensure the reactor is in a safe shutdown condition.
1.2 In addition to de-energizing the shutdown and control rod drive mechanisms, a reactor trip will initiate a turbine trip and, in conjunction with a low TAVE (554°F)
- initiate a feedwater isolation signal. This instruction delineates the actions required to ensure both of these have occurred. ~
1.3 In the event a reactor trip is required and has not been automatically initiated or the reactor fai~s to trip when initiated, this is identified as an "Anticipated Transient Without a Trip" Event (ATWT Event}. This instruction provides the necessary actions to ensure the reactor is placed in a safe shutdown condition for this event.
2.0 INITIAL CONDITIONS 2.1 Any of. the following conditions will lead to a reactor trip and to an automatic plant shutdown. The condition causing the trip will be back lighted in red on the first out overhead annunciator panel (Section F).

EMERGENCY INSTRUCTION EI-I-4.3 REACTOR TRIP 1.0 PURPOSE 1.1 A reactor trip is initiated automatically by the Reactor Protection System if unsafe operating conditions are approached*. It may also be initiated manually from the control console. This instruction provides tho ~r.tions required to ensure the reactor is in a safe shutdown condition.
1.2 In addition to de-energizing the shutdown. and control rod drive mechanisms, a reactor trip will initiate a turbine trip a~d, in conjunction with a low TAVE (554°F) initiate a feedwater isolation signal. This instruction_
delineates the actions required to ensure both of these have.occurred.
1.3 In the event a reactor trip is required and has not been automatically initiated or the reactor fails to trip when initiated, this is identified as an "Anticipated Transient Without a Trip" Event (ATWT Event). This instruction prdvides the necessary actions to ensure the reactor i-s placed in a safe shutdown condition for this event.
