Reprocessing of Spent Nuclear Fuel: A Policy Analysis

Nuclear spent fuel reprocessing has lately reemerged as a subject of debate in the energy policy world. Since a 1977 Presidential Directive which deferred reprocessing of spent nuclear fuel (SNF), the United States has utilized a 'once through' or 'open cycle' system of nuclear fuel processing, which leaves most of the energy content in uranium unused. Current reprocessing technology increases the cost of nuclear electricity while only offering limited storage benefits. Advanced technologies have the potential to increase proliferation resistance, the need for more geologic repositories, and allow the United States to regain an international presence in reprocessing technology. The United States should not immediately engage in spent fuel reprocessing, but should begin aggressive research and development for new reprocessing technologies. (authors)
