Aqueous Homogeneous Reactor

An aqueous homogeneous reactor (AHR) is a type of nuclear reactor built as a two-chamber vessel, with an interior reactor chamber surrounded by an outer cooling and moderating jacket chamber. Rather than using solid fuel rods, it dissolves soluble nuclear salts, usually uranium sulfate or uranium nitrate, directly in water. The dissolved fuel is mixed with heavy or light water, which partially moderates and cools the reactor, while the water in the outer jacket chamber provides further cooling and moderation.
