10. IAAT LDST level CANNOT be maintained, THEN perform Step ii.

RNO: GO TO Step 12.

11. Perform the following:

• Open IHP-24

• Open 1HP-25

• Close 1HP-16 Page 22 of 25

Time__[ Position Applicants Actions or Behavior Crew response:

OATC/BOP EOP Enclosure 5.5 (Pzr and LDST Level Control) (if needed)

12. IAAT additional makeup flow to LDST is desired, AND 1A BLEED TRANSFER PUMP is operating, THEN dispatch an operator to close 1CS-48 (1A BHUT Recirc) (A-i-i 07, Unit 1 RC Bleed Transfer Pump Rm.).

13. IAAT two Letdown Filters are desired, THEN perform the following:

• Open 1HP-17.

• Open 1HP-18

14. IAAT of the following exist:

• Letdown isolated

• LPSW available

• Letdown restoration desired THEN perform Steps 15 33 -

RNO: GO TO Step 34.

34. IAAT it is determined that letdown is unavailable due to equipment failures or letdown system leakage, THEN notify CR SRO to initiate AP/32 (Loss of Letdown).

35. IAAT> 1 HPI pump is operating, AND additional HPI pumps are NO longer needed, THEN perform the following:

A. Obtain SRO concurrence to reduce running HPI pumps.

B. Secure the desired HPI pumps.

C. Place secured HPI pump switch in AUTO, if desired.

36. IAAT all the following conditions exist:

• Makeup from BWST NOT required

• LDST level > 55

• All control rods inserted

• Cooldown Plateau NOT being used THEN close:

• 1HP-24

• 1HP-25

37. Verify ICS-48 (1A BHUT Recirc) has been closed to provide additional makeup flow to LDST.

RNO: GO TO Step 39.

39. Verify two Letdown Filters in service, AND only one Letdown filter is desired.

RNO: GOTOStep4l.

41. WHEN directed by CR SRO, THEN EXIT this enclosure.

These actions are complete when EOP Enclosure 5.5 (Pzr and LDST Level Control) is exited.
