SUBJECT:

H. B. ROBINSON, UNIT 2 -

AFW FLOW REQUIREMENTS The.Reactor Systems Branch has reviewed the response by H. B. Robinson, Unit 2, to the NRC information request of May 2, 1980 relating to the basis for auxiliary feedwat r flow requirements.

Our comments are as follows:

1. The'auxiliary feedwater system must have a capacity to supply 300 gallons per minute total to two 'steam generators following a loss of-feedwater event (station blackout) or a feedwater line break event.

2. The auxiliary feedwater system must be guaranteed to sa4is4fy the flow requirements listed in item 1 above for the appropriate initiating event considering theAuxiliary Systems Branch failure criteria for the auxiliary feedwater system.

3.

Tki Rctwr Systems Branch considerations impose no upper bound for maximum permissible auxiliary feedwater flow rate for this plant; however, an upper limit may be set based upon another branch'.s criteria,.for example, Containment Systems Branch. Containment Systems Branch may be consulted to verify maximum permissible auxiliary feedwater flow rate.
