SECTION "A" I UNIT 2 SCO ACTIONS l ****************************************************************************** l l CAUTION l Interlocks that would normally prevent inadvertent draining of the reactor l coolant to the suppression pool, due to improper valve positioning, are 1 l

bypassed when operating the valves manually or with the ASSD switches selected .

for local operation. Caution must be exercised when performing RHR valve operations in this procedure to ensure that each valve operation is fully ,

completed prior to performing the next sequential operation. j (This caution is a result of SOER 87-2 " Inadvertent draining of reactor vessel !

, to suppression pool at BWRs", and may not be removed without concurrence of '

l Regulatory Affairs.)

l ******************************************************************************

I !

l 1. OBTAIN the ASSD equipment cabinet key from the Unit SCO key '

locker.

15. IE any of the following conditions should occur THEN rapidly DEPRESSURIZE the reactor vessel using Attachment 1.

a. IE reactor water level cannot be maintained above 10 inches.

b. IE drywell temperature monitored on CAC-TR-778, Point 1, is higher than reactor temperature AND i r: tor water level cannot be maintained l above 20 inches.

c. lE average drywell air temperature cannot be maintained below 300*F as determined by Calculation Sheet 1.

j BSEP-2/ASSD-05 Page 5 of 83 Rev. 21

NOTE The loss of drywell cooling can be confirmed by monitoring Points #1, #3 and #4 on recorder CAC-TR-778 located on the Remote Shutdown Panel. The time the event occurred can be determined from the chart paper speed.

d. IF average drywell temperature cannot be calculated AND (1) A loss of drywell cooling has occurred AND (2) Reactor vessel cool down rate of 100*F/hr or greater has NOT started within one hour of the loss of drywell cooling.

a. RCIC is operational AND ,

i

b. N, Backup Switch and circuit alignment for l SRV operation is complete AND 1 1

c. 4 KV Bus E4 is energized to provide N 2 backup for SRV operation AND

d. Reactor water level is being maintained greater than 20 inches, THEN

e. DIRECT Unit 2 RSDP/PMI Reactor Operator to START l reactor depressurization and cooldown using SRVs and l RCIC.

E0_.TE l

The RSDP and Emergency Switchgear Operators will direct most activities in this procedure.

17. MONITOR communications AND VERIFY the following conditions and events take place: l

a. Conditions do not approach rapid depressurization requirements.

b. . Reactor water level is being maintained I above 20 inches by RCIC.

l

c. WHEN RCIC and SRV pneumatics are available, reactor depressurization and cooldown have been initiated.

i CAUTION Interlocks that would normally prevent inadvertent draining of the reactor coolant to the suppression pool, due to improper valve positioning, are l bypassed when operating the valves manually or with the ASSD switches selected for local operation. Caution must be exercised when performing RHR valve operations in this procedure to ensure that each valve operation is fully completed prior to performing the next sequential operation.
