The Solution High-Energy Burst Assembly II (SHEBA-II) has been in operation at Los Alamos National Laboratory for more than 4 yr. During that time it has been fueled exclusively with an aqueous solution of uranyl fluoride. However, because of the corrosiveness and viscosity of uranyl fluoride, it is planned eventually to use an aqueous solution of uranyl nitrate as fuel instead. This paper evaluates the likely change in spectrum and critical height accompanying this changeover and investigates its impact on a set of proposed experiments.
