Time Position Applicants Actions or Behavior Crew Response:
EOP Enclosure 5.9 NOTE
- Loss of the condensate system for 25 minutes results in cooling down to LPI using the ADVs. If NO HWPs are operating, continuing this enclosure to restore the condensate system is a priority unless the CR SRO deems EOP activities higher priority. The 25 minute criterion is satisfied when a HWP is started and 1C-lO is 10% open.
- If the condensate system is operating, the remaining guidance establishes FDW recirc, monitors and maintains UST, and transfers EFDW suction to the hotwell if required.
- 12. Notify CR SRO to set priority based on the NOTE above and EOP activities Note: The SRO should determine that restoring the secondary side of the plant is not a priority at this time and direct the RO to continue in Rule 3.
EOP Rule 3 Continued
- 11. Ensure Rule 8 (Pressurized Thermal Shock (PTS)) is on progress or complete
- 12. WHEN directed by CR SRO, THEN EXIT this rule Note: When Rule 5 is complete, the I B MDEFDW pump will trip. This will require Rule 3 to be reinitiated to start the TD EFDW pump to feed the lB SO.
When the team determines that the I B MDEFDW pump has tripped the SRO should direct that Rule 3 be re-performed. The SRO could also direct the performance of a Symptoms Check in which case the TO EFWP could be started per the Symptoms Check. Rule 3 should still be performed.

Normally, IRC-1 will open at 2205 psig increasing and close at 2155 psig decreasing. Since IRC-1 is failed open, the operator will be required to control RCS pressure manually with IRC-3.
Note: The SRO/OATC may elect to trip the Reactor during this transient per SOMP 1-02 and OMP 1-18 Attachment J (Plant Transient Response).
During abnormal operating conditions a manual reactor trip shall be initiated if any of the following conditions occur:
- Reactor power level approaches any operating limit
