“…The reduction of fast neutrons and the increase of thermal neutrons as the distance is increased are similar to measurements carried out in a Nuclear Chicago model 9000 subcritical reactor [22], and a subcritical reactor with TRIGA reactor fuel [23]. In figures 7, 8, 9, 10 and 11 the distribution of neutron fluence per history are shown for mini subcritical reactor with 1, 2, 3, 4, and 5 fuel rings, the shape of neutron fluence distribution is alike to the distribution reported for the Jordan subcritical reactor [24]. As the rings of fuel are added the neutron distribution is enhanced due to neutrons produced during fission.…”

A mini subcritical nuclear reactor was designed using Monte Carlo methods. The reactor has light water as moderator, natural uranium as fuel, and a 239PuBe neutron source. In the design uranium fuel was modeled in an arrangement of concentric rings: 8.5, 14.5, 20.5 26.5, 32.5 cm-inner radius, 3 cm-thick, and 36 cm-high. Different models were made from a single ring of natural uranium to five rings. For each case, the neutron spectra, the neutron fluence distribution, the effective multiplication factor, the amplification factor, and the reactor power were estimated. The ambient dose equivalent rate outside the mini reactor was also estimated. The maximum value for the keff (0.78) was obtained when five rings of fuel were used; this value is close to 0.86 which belongs to a Nuclear Chicago subcritical reactor which requires almost twice the amount of uranium than the mini subcritical reactor.
