Annular Core Research Reactor High Flux Neutron Radiography Facility

Abstract

The High Flux Neutron Radiography Facility (HFNRF) is a new neutron radiography facility designed, built, and operated by Sandia National Laboratories (SNL). The HFNRF uses the dry central irradiation cavity of the Annular Core Research Reactor (ACRR) and consists of a collimator assembly, an experiment support structure, and an imaging system. A key element in operation of the HFNRF is the reactor's reactivity control system.
