When the MFP EBOP has started, what is its flow path?

The flow path of the Main Feedwater Pumps (MFP) Emergency Backup Oil Pump (EBOP) typically bypasses both the oil cooler and strainer to ensure that hydraulic oil pressure is quickly and effectively supplied during emergency situations. This design choice prioritizes immediate functional operation by minimizing pressure drop and preventing potential contamination or flow restriction that might occur if the oil had to pass through the strainer or cooler first.

By bypassing these components, the system can deliver oil directly to critical components that require lubrication and actuation without delay. This is particularly crucial during emergency scenarios where maintaining system pressure and function can be vital for operational continuity and safety. The ability to respond rapidly in emergencies is a key design consideration in auxiliary equipment like the MFP EBOP.
