The fission process produces not only isotopes of interest as heat sources, but elements, e.g., rhodium, palladium, and xenon, that may ultimately be used as articles of commerce. Augmenting the supplies of the same rare elements as derived from nature such materials are produced in all nuclear power reactors and the revenue from their sale could be used to reduce nuclear power costs. A cautious optimism toward this possibility is suggested by consideration of the properties of these materials, methods and costs of their production and separation, and their uses and possible market value.
