The Criticality and Some Potentialities of “Cavity Reactors”

George M. Safonov

ResearchPublished 1955

An attempt to determine a critical equation for reacting systems with cores of very low density, thermally fissionable material surrounded by a moderating reflector. The critical mass of cavity reactors which employ U***, U***, and Pu*** for fuel and D*O, Be, and C for reflector is given as a function of core size. In addition, possible implications of cavity reactors are discussed.
