A Study of the Concept of a Fission-Plate Converter as a Source for an Epithermal Neutron Beam

  • Hungyuan B. Liu

It has been suggested that a Fission-Plate Converter (FPC) at a reactor can enhance the intensity of an epithermal neutron beam produced by the reactor. By computer modeling, this concept has been applied to two sets of reactors to study how effective a FPC might be. The first set of reactors contains high-powered research reactors and is represented by the Missouri University Research Reactor and the Georgia Institute of Technology Research Reactor. The second set combines the FPC into the core of a low-powered reactor, yielding a thin, large area, reactor that we call a slab reactor. For these reactors, epithermal fluxes above 1 × 109 n/cm2.sec are predicted while the fast-neutron doses per epithermal neutron are < 3 × 10−11 cGy.cm2/n.
