[en] The feasibility of photochemically fractionating the actinides in nuclear waste processing is evaluated on a preliminary basis. The data indicate that there are potentially useful photoredox reactions. However, there is a serious lack of data on photochemical parameters for the solution conditions existing in nuclear waste processing. The problem areas relevant to photochemical processing are identified. The experimental areas that must be investigated in order to further evaluate the photochemistry are defined. A research and development program is outlined to determine whether these photochemical reactions can be successfully modified and adapted to a functional actinide fractionating process
