use of AFN-P01 (Non-essential Motor Driving Aux Feed pump). Although all feed is lost during SPTAs, due to loss of MVAC safety function, the CRS should proceed to the Functional Recovery Procedure since the LOAF EOP will not restore a class bus.
Scen 2: End Point - What is AFN-P01? Due to the loss of PBA-S03 (Class 4 kV bus -

29 and 9 need to be reversed? Event 8 has been deleted. SI setpoint will be exceeded. Break is upstream of the Main Steam Isolation Valves.
Scen 3: Event 10 - Critical Task states The critical task refers to isolating Feed to the SG isolated but description states stop SG when the Differential pressure exceeds 30 feeding SG - which is correct? the setpoint when it should stop automatically.
