A novel method for energy production using Am-242m as a nuclear fuel

A novel system for energy production is presented. This system has a modula r composition of homogeneous reactors with H2O and Am-242m as a fuel. These reactors are spheres of 0.11-m radius and 1-MW(thermal) power and with a c ritical mass of 0.0201 kg of Am-242m. The advantages of homogeneous reactors are constant fuel reprocessing and c onstant refueling. As a result, there is a reduction of fission products, w hich improves the ratio of natural cooling to heat production with respect to a loss-of-control accident (LOCA) and other safety aspects. Homogeneous reactors also have a large negative temperature coefficient and small inher ent excess reactivity during operation. The reactor concept we have presented for a very small, homogeneous reactor , further enhances the safety aspects in the case of a LOCA; because of a l arge surface-to-volume ratio. The improved safety, the simplicity, and the small volume should compensate for the use of an unconventional nuclear fuel.
