NOTE

• Loss of the condensate system for 25 minutes results in cooling downto LPI using the ADVs. If NO HWP5 are operating, continuing thisenclosure to restore the condensate system is a priority unless the CRSRO deems EOP activities higher priority. The 25 minute criterion issatisfied when a HWP is started and iC-b is 10% open.

EXAMINER NOTE: Neither of the criteria in the note below are met sono actions are required in RuleS. If the crew pulls Rule 8 as directedby Rule 5, they should immediately EXIT back out based on the note atthe beginning.

NOTEThis rule is invoked under either of the following conditions:• A cooldown below 400°F T at> 100 °F/hr has occurred.• HPI has injected through an open or throttled open 1 HP-26, 27, 409,

410 with a RCPs OFF.

• SCM must be minimized. The following methods may be used at thediscretion of the CR SRO:

• Throttling HPI per Rule 6 (HPI)

• De-energizing Pzr heaters

• Using Pzr normal spray

• Using Pzr aux spray

• Using PORV

• Throttling LPI {22}

• Once RCS temperature is stable, a 1-hour hold of RCS temperaturemust be performed unless a LOCA or SGTR is in progress. Use T0 inloop with an operating RCP use CETCs if NO RCPs are operating.

• Once invoked, SCM shall remain minimized until Engineering hasperformed an evaluation and determined that PTS restrictions NOlonger apply. Starting RCPs and/or restoring cool down rates to normalvalues do NOT negate the need for this evaluation.

NOTE

• Loss of the condensate system for 25 minutes results in cooling downto LPI using the ADVs. If NO HWPs are operating, continuing thisenclosure to restore the condensate system is a priority unless the CRSRO deems EOP activities higher priority. The 25 minute criterion issatisfied when a HWP is started and 1C-10 is 10% open.
