l FUNCTION

. - LIMITING SAFETY SYSTEM SETTINGS B. Neutron Flux, The Rod Block setting shall be Control Rod Block FRP  !

S s [(0.90 x 10) W + 53.1] [MFLPD]

with a maximum setpoint of 108% for core flow equal to 61 x 106 lb/hr and j greater.

The definitions of S, W, FRP and MFLPD used above for the APRM scram trip apply.

The ratio of FRP to MFLPD shall be set equal to 1.0 unless the actual operating value is less than 1.0, in which case the actual operating value will be used.

This adjustment may be accomplished by increasing the APRM gain and thus reducing the flow referenced APRM rod block curve by the reciprocal of the APRM gain change.
