-,'d:E-50B -,'d*CV-0501.
- g. Feedwater Regulating Val~es close on Steam Generator Low Pressure to the Steam Generator with the low pressure (500 psia) **CV-0701 on
- E-50A and/or **CV-0703 on **E-508.
- h. Feedwater Regulating Bypass Valves close on Steam Generator Low Pressure to the Steam Generator with the low pressure (500 psia)
- **CV-0735 on **E-50A and/or **CV-0734 on **E-508.

- 3.0 3.1 IM.MEDIATE ACTIONS INSIDE CDNTAIN1'1ENT Verify reactor trip, carry out EDP 1, "Immediate Actions".
3.2 Check Safety Injection initiated, manually initiate if necessary.
3.3 Check Containment Spray initiated.
3.4 Check that the Main Steam Isolation Valves have closed on Containment High Pressure (5.3 psig), Steam Generator low pressure (500 psia).
- '**'*E-50A *';-;'*CV-0510 and *b'*E-50B *b'*CV-0501.
3.5 Check that the Feedwater Regulating Valves have closed on St~am Generator low pressure 500 psia, (valve posi~ion indication only)
- E-50A **CV-0701 and **E-50B **CV-0703.
3.6 Check that the Feedwater Regulating Bypass T~-alves have closed on Steam Generator low pressure 500 psia (valve posi~ion indication only)
- E-50A **CV-0735 and **ESOB **CV-0734.
3.7 Check Containment Isolation ini tiate<il. *
- 3. 8 Place Turbine Generator Turning Gear Hotor -::.-.:-K-2 Control Switch in "PULL *~
TO LOCK".
3*9 ACTIVATE SITE E~IERGENCY PLAt~. REFER TO SIT::: I.f1ERGEXCY U1PLEHENTATION PROCEDURE EI-1.
4.0 SUBSEQUENT ACTIONS NOTE: Steam Generator and Pressurizer level indicaLion will be affected by containment pressure and temperature during accident conditions. Use Attachments 1 thru 5 to calculate actual le...-el conditions.
- 4. 1 Verify actuation of the following:
- a. Safety Injection (Attachment 6).
- b. Containment Spray (Attachment 7).
- c. Containment Isolation (Attachment 8).
4.2 Verify accident diagnosis per Attachment 9.
4.3 Place Iodine Removal System **T-0102 Control Valve Switches, **CV-0437A and *'**'*CV-0437B to the "Defeat Auto" p o SlLlO::l. *~
- 4.4 Determine which Steam Generator has the bre.::K by observing pressures and levels in the Steam Generators.

- INSIDE CONTAINHENT 4.5 When the damaged Steam generator has been identified, immediately stop Auxiliary Feedwater flow to the affected generator.
4.6 Check Containment Air Coolers functioning properly. If containment pressure is less than or equal to 20 psig, then Stop the Containment Spray Pump (s) ,.,.,.,P-54/\, ,*,,*,P-54B and ,*,,*,P-54C. If the containment pressure starts to increase, restart the Containment Spray Pump(s) as necessary to stop the pressure increase.
4.7 As soon as conditions allow (containment pressure is less than or equal to four (4) psig) reset CHP, insure ""'""'P-54A, """'*P-54B and ,*,,*,P-54C are off then close Containment Spray Header Valves **CV-3001 and **CV-3002.
4.8 When the pressurizer level starts to recover and approaches an indicated level of 30% start removing the Charging Pump(s) ""'""'P-SSA, "P-SSB and/or
- P-55C from operating as necessary by placing the respective hand switches to the stop position. The Charging Pumps can be started and stopped as necessary to control the pressurizer level near normal zero power level of 42% (indicated level). The Selector Switches for """~P-55B and/or **P-SSC should be placed to the manual position to obtain manual operation of these pumps, as necessary. , ,<:.! ;_
4.9 If conditions allow, reset SIS. R~fer to EOP-1 for required conditions to be met prior to reset.
4.10 When CHP and/or SIS has been reset and component cooling water has been verified going to the Containment, open ;'d'CV-2009 to establish letdown flow. If the Failed Fuel .Honi tor 'b'*RIA-0202 alarms, immediately isolate letdown and sample the Primary Coolant System per ONP 11.
NOTE: Do not attempt to operate LPSI valve ;'d'.t-10-3008 if the water level in the containment is greater than 85% indicated.
4.11 When conditions allow, place the Charging and Letdown in automatic per SOP 2A.
4.12 After letdown has been established for approximately 15 minutes, have a PCS boron sample taken to verify Cold Shutdown Boron Concentration.
4.13 When the Containment pressure and the Primary Coolant System pressure, temperature and inventory are under control, exit this procedure and initiate cooldown of the PCS using the Natural Circulation Procedure ONP 21.
