- 1. START available RHR loops in the suppression pool cooling mode.
(OP-17)
- 2. IF service water is NOT available to ' het RER heat exchangers. THFN available RHR loops should be used to recirculate the suppression pool to sintaire local temperature differences.
- 3. LOC suppression pool temperature at thirty-minute intervals and VERIFY it to be less than or equal to 120'F.
- 4. }F suppression pool temperature reaches 120'F. THEN COMMENCE a reactor cooldown at normal cool down rates UNTIL reactor pressure is less than 200 psig.
S. IF suppression pool temperature CANNOT be maintained in the "SATE" region of the Heat Capacity Temperature Limit graph (see figure 1 SP/T). TNEN KAINTAIN reactor pressure in the "SAFE" region.
- 6. 1F suppression pool temperature and reactor pressure CANNOT be restored and maintained in the "SAFE" region of the Heat Capacity Temperature Limit graph (see Figure 1. SP/T). THEN reactor depressurination is required. DEPRESSURIZE ti.e reactor per the End Path Procedure.
- 7. IF suppression pool temperature reaches 160*F. THEN CONSULT Technical Specifications for actions required prior to startup.

eeeeeeeeeeeeeeee**eneee***eeeeeeen.eeeeeeeee****een+ee ee**ee**e*****.nemeneae NOTE All dryvell coolers trip and lock out on ar. LOCA signal.
- 1. START all dryvell coolers.
- 2. VERIFY RBCCW Syster opiration and alignment to dryvell.
- 3. IF a loss of dryvell cooling has occurred. TNFN COMMENCE a reactor ,
cooldown at normal cooldovn rates, as soon as possible, in order to ;
limit dryvell terperature increase.
~-~
4 IF dryvell temperature near uncompensated level instrument reference Tess is not in the "SAFE" region of the RPV Saturation Ltatt graph ;
(see Figure 1, DV/T). TNTN reactor vessel flooding is required. !
