Abstract : In support of its mission the Armed Forces Radiobiology Research Institute (AFRRI) operates a medium sized research nuclear reactor. The reactor is used to generate radiations, primarily neutrons and gamma rays, which are used to conduct experimental biomedical research and to produce isotopes. The radiations are delivered to the experiments in one of two ways: A pulse operation delivers a very short burst of high power, or a steady state operation delivers a longer, continuous low- to medium-power exposure. The reactor is also used to train military personnel in reactor operations. TRIGA is an acronym for Training, Research, and Isotope, General Atomics. Mark-F is the specific General Atomics Reactor model, distinguished by a pool, a movable core, exposure room facilities, and the ability to pulse to momentary high powers. Reactor operations at AFRRI began is 1962. In 1965, a change was made from aluminum clad to stainless steel-clad fuel elements. Currently more than 150 multiple exposure experiments are performed each year using the reactor. Keywords: Exposure Facilities; Modes of Operation; Cerenkov Radiation.
