3. DESCRIPTION OF PROGRAM OR FUNCTION

RKFB is a space-independent point-kinetics reactor code. It provides a range of reactivity input options, trip control absorbers, and a multiple lumped-parameter temperature feedback model. It is applicable to Materials Testing Reactors of the DIDO class. A reactivity controller option permits simulation of an automatic control system.
