IIIEE Core Cooling Without Injection NO.05-S-01-EP-6 REV.B 2 AGE of 1

2 1.0 ' PURPOSE The purpose of this procedure is to cool the reactor core with stea.g sufficiently to maintain peak cladding temperature (PCT) below 2200 F.

2.0 ENTRY CONDITIONS This procedure is entered from EP-4 (Level Restoration) when all of the following conditions pecuring simultaneously:

O z.1 concition 1 IdV water level cannot be determined and no injection or alternate injecticn subsystem is linedup fcr injectica with at least cne m =nning.

C 2.2 Conditica 2 All cf the following si::.11taneously:

2.2.1 RPV water level has decreased to 0" (TAF), and 2.2.2 CPD is not cperati m, a.M 2.2.3 No injectica cr alternate injection subsysten is lined up with at least cne purp runnig.

3.0 OPERATOR ACTIONS

/7 3.1 If RPV water level cannot be determined or RPV water level cecreases to core midplane (-75" on fuel 'Eone instrumentation),

then open one SRV.

NOTE Fuel zone instrumentation is as follows:

P601 - RHR Section - B21-R615 P610 - RCIC Section - 321-R610 6

3.2 As RPV pressure decreases, open additional SRV's as required by the following table:

TOTAL NUMBER OF RPV PRESSURE (psic)

O between 800 and 500 2

_/ 7 between 500 and 350 3
