A.
PURPOSE - This procedure provides the necessary instructions for transferring the Safety Injection system and Containment spray system to recirculation modes of operation.
B.
ENTRY CONDITIONS / SYMPTOMS 1.
ENTRY CONDITIONS - This procedure may be entered from:
a.
E-1, LOSS OF REACTOR OR SECONDARY COOLANT, or, b.
ECA-0.2, LOSS OF ALL AC POWER WITH SI REQUIRED, or, c.
ECA-2.1, UNCONTROLLED DEPRESSURIZATION OF ALL STEAM GENERATORS, or, d.
FR-C.1, RESPONSE TO INADEQUATE CORE COOLING, or, e.
FR-C.2, RESPONSE TO DEGRADED CORE COOLING, or, f.
FR-C.3, RESPONSE TO SATURATED CORE COOLING, or, g.
FR-H.1, RESPONSE TO LOSS OF SECONDARY HEAT SINK, or, pg h.
FR-Z.1, RESPONSE TO HIGH CONTAINMENT PRESSURE, on low (j

o IF OFFSITE POWER IS LOST AFTER SI-RESET, THEN SELECTED SW PUMPS AND ONE o
CCW PUMP WILL AUTO START ON EMERGENCY D/C. MANUAL ACTION WILL BE REQUIRED TO RESTART SAFEGUARDS EQUIPMENT.
CONSULT WITH RADIATION PROTECTION BEFORE DISPATCHING PERSONNEL TO o
AUXILIARY BUILDING.
NOTE:
o FOLDOUT page should be open and monitored periodically.
Adverse CNMT values should be used whenever CNMT pressure is-o greater than 4 psig or CNMT radiation is greater than 10+05.R/hr.
IF RWST level is less than 28% 6JN nO GREATER THAN 113 INCHES CNMT. sump B level is less than 113 inches, THEN go to ECA-1.2,-

3 Establish Adequate SW Flow:
a._ Verify at least two SW pumps -
- a. Start additional SW pumps as RUNNING power supply permits (258 kw each).
IF only 1 SW pump operable, THEN perform the following:
- 1) Ensure Attachment MIN SW is complete.
- 2) Go to Step 4.
- b. Verify AUX BLDG SW isolation
- MOV-4615 and MOV-4734
()
- c. Perform the following:
flow to CCW Hxs - GREATER THAN 5000 GPM
- 1) Isolate SW!to screenhouse and i
air conditioning headers.
/i MOV-4609 and MOV-4780
{
