4 MC03 & MC04B C (BOP) R (OATC) SJAE Failure resulting in degrading vacuum and power reduction.
5 ED12 M (Crew) Feedwater Line Break inside the Drywell (trip of both FW Pumps and Reactor SCRAM
) 6 RC01 C (OATC) RCIC Auto Initiation Failure 7 C (Crew) RCIC injection is in
-effective; Restore HPCI [CT - RCIC injection is in
-effective due since RCIC is aligned to the same line as where the feed line break is located. Failure to restore HPCI will cause RPV level to drop below TAF.]
CONTIGENCY
- If crew fails to restore HPCI and RPV drops to TAF, then BEFORE RPV level drops to
-149" Emergency Depressurize (Blowdown) and restore RPV level above TAF using Low Pressure ECCS.
