9 9 A. TITLE - Reactor Building Closed Cooling Water System Recovery B. ENTRY CONDITION RBCCW header pressure CANNOT be maintained above 60 psig.

C. OPERATOR ACTIONS

1. TRIP the RBCCW pumps.

2. TRIP the reactor recirculation pumps.

3. TRIP the CRD pumps.

4. TRIP the RWCU pumps.

5. ISOLATE RWCU by closing the folicwing valves:

a. RWCU INBOARD ISOL VLV, G31-F001 l

b. RWCU OUTBOARD ISOL VLV, 231-F004 l

6. CLOSE RBCCW TO DW ISOL VLVS, RCC-V28/52 l

7. MONITOR drywell pressure and temperature.

8. IF the RBCCW pumps have lost electrical power OR will NOT start.

THEN CONTINUE in Section 1 on page 4 of this procedure.

9. IF the RBCCW pumps were running AND the header pressure COULD NOT be maintained above 60 psig, THEN CONTINUE in Section 2 on page 5 of this procedure.

BSEP/Vol . VI/EOP-01-SRP-RBCCW Page 3 of 6 Rev. 2

Section 1 - The RBCCW pumps have lost electrical power OR will not start.

NOTE The RBCCW pumps will trip if there is a loss of  ;

off-site power or a generator lockout concurrent with a LOCA signal. The pumps VILT. NOT RESTART UNTIL one of these signals is clear.

1. IF the affected unit's 4KV E buses are de-energized, THEN PERFORM the "Auxiliary Electrical Power System Recovery Procedure" concurrently with this procedure.

2. CHECK pump breakers locally.

3. RESET thermal or magnetic trips as required.

4 NOTIFY maintenance to begin repairs as necessary.

5. WHEN electrical power is restorel, THEN CONTINUE in Section 3 on page 6 of this procedure.

r-Section 2 - RBCCW pumps are not maintaining the RBCCW header prensute above 60 psig.

~~

1. IF the RBCCW head tank level is low (UA-3 1-5 or local indicator, RCC-LC-663), THEN PERFORM the following steps:

a. WALK DOVN accessible system piping to locato leakage.

b. CHECK dryvell floor drain and equireent drrD; sump leakage rate.

c. ISOLATE any source of leakage that is fnta d .

d. NOTIFY maintenance to begin repairs 49 necessary.

NOTE Nermal RBCCW head tank level is bweveen 15 inches and 25 inches from the top of th6 head tank.

~~

2. WHEN system leakage has been isolated, repaired. OR it has been deternined that no leakago exists THEN RESTORE tee RBCCW head tank level to normal and CONTINUE in Section 3 on page 6 of this procedure. '

BSEP/Vol. VI/EOP-01-SRP-RBCCW Page $ of 6 Rev. 2

r Section 3 - Restoration of the RBCCW System

~~

1. START RBCCW pumps as necessary to maintain RBPCW header pressure above 60 psig.

2. IF the RBCCW header pressure is below 60 psig, THEN PERFORM the following steps:

a. MONITOR RBCCW header pressure locally (RCC-PI-671-2) to ensure validity of the 3ow pressure alarm.

. VERIFY proper valve alignment and pump coup 1.ing integrity.

c. IF RBCCW header pressure CANNOT be restored AND maintained above 60 psig, THEN RETURN to Step C on page 3 of this procedure.

3. IF an RBCCW 1eak in primary containment is N(T suspected THEN OPEN RBCCW TO DW ISOL VLYS, RCC-V28/52.

l i

4. START the CRD system (0P-07).

5. START RWCU pumpe (OP-14).

6. START reactor recirculation pumps (OP-02).
