If while executing Steps 5.3 and 5.4, RPV water level can be determined, continue in this procedure at Step 6.

5.3 Determine the RPV is filled by three or more of the following methods:

a.

RPV level indications upscale on fuel zone, wide range and narrow range channels.

b.

RPV skin temperature drop coincident to initiation of flooding with sustained downward trend.

c.

SRY acoustic monitors on open SRVs indicate flow.

d.

SRV tailpipe temperature comparison indicates flow.

e.

Restart of RRC-P-1A or RRC-P-1B provides stable jet pump flow indication.

5.4 If it can be determined that the RPV is filled or RPV pressure is at least 100 psig above suppression chamber pressure, term-inate all injection into the RPV and reduce RPV water level:

Terminated Injection a.

Open RPV head vents MS-V-1 and MS-V-2.

b.

Confirm SRV's open.

c.

Open RHR-V-67 until approximately 6 additionaL inches of stem have been exposed.

d.

Open RHR-Y-8 and RHR-V-9.

e.

Close RHR-Y-S, RHR-V-9, and RHR-V-67 when either level indication comes on scale or before exceeding the Maximum Core Uncovery Time Limit.
