In the meeting, FPC provided technical clarification for each SBLOCA scenario, system designs, system configurations, and operator actions. During its discussion, FPC stated that high pressure injection (HPI) flow throttling would be used when in recirculation mode (low-pressure injection taking a suction from containment sump and feeding HPl pumps). The staff questioned whether FPC has been approved to use flow throttling and requested that FPC provide a reference to the staff's approval for the use of flow throttling.

In the meeting, the staff also discussed the draft Emergency Operating Procedures (EOPs) provided in the June 14,1997, submittal.
