EMERGENCY INSTRUCTION I-4.0 SAFETY INJECTION INITIATION 1.0 PURPOSE 1.1 This instruction is provided to present the immediate automatic and manual actions required to be performed on the receipt of any Safety Injection Actuation, whether automatically or manually initiated.

1.2 This instruction contains the information required to direct the operator to the appropriate Emergency Instruction to cope with the existing plant conditions.

2.0 INITIAL CONDITIONS 2.1 Safety Injection has been initia~ed,. either automatically or manually.

3.0 IMMEDIATE ACTIONS 3.1 Verify the following automatic actions have occurred.

3.1.1 REACTOR TRIP by verifying all control rods are fully inserted by checking the individual rod position indications and _rod bottom lights.

a. If any control rods do not indicate full insertion, initiate a manual reactor trip.

NOTE The Rod Position indications & Rod Bottom lights may be erroneous due to an adverse containment- environment.

3.1.2 ACCIDENT LOADING OF the SAFEGUARDS. EQUIPMENT has taken place and the following equipment is running by observing the indicating lights on the status panel on 1RP4 or by observing the control bezels for each of the following:

a. Centrifugal Charging Pumps

b. Safety Injection Pumps

c. Residual Heat Removal Pumps

d. Auxiliary Feedwater Pumps (Motor Driven)

e. Service Water Pumps

f. Containment Fan Coil Units in slow speed.

3.1.4 TURBINE TRIP by verifying unit trip light on the EH console and turbine speed decreasing.

a. If the turbine does not indicate a tripped condition, initiate a manual trip from the control console.

3.1.5 MAIN FEED PUMPS tripped by observing the indications on the Control Bezel.

a. If either pump does not indicate a tripped condition, initiate a manual trip from the

.control console.

3.1.6 FEEDWATER ISOLATION by observing the indicating lights on the Feedwater section of !RP4.

3.2 Verify Safety Injection Pump flow to the Cold Legs from the operating Safety Injection Pump(s) by observing the discharge flow meters on the control console.

3.3 When RCS pressure decreases to less than 1500 psig as read on the Wide Range Indicators on the control console, perform the following:

3.3.1 STOP all Reactor Coolant Pumps.

3.3.2 CLOSE 1CV139,1CV140 The Charging Pump Recirc Stop Valves.
