What the grant funds

Request for Information (RFI) on Transmutation of Nuclear Waste This is a Request for Information (RFI) only. This RFI is not accepting applications for financial assistance. The purpose of this RFI is solely to solicit input for ARPA-E consideration to inform the possible formulation of future programs. ARPA-E has as one of its goals the development of energy technologies that improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel. To meet this goal, ARPA-E has established a suite of programs (GEMINI, MEITNER, ONWARDS, CURIE) that have the potential to reduce the volume of radioactive waste by a factor of 10 or more and the needed time for storage by a comparable amount. Nuclear transmutation of key fission products and actinides in the remaining radioactive waste has the potential to reduce the volume and storage time by additional orders of magnitude. The purpose of this RFI is to solicit input for a potential future ARPA-E program focused on the development of technologies to support advances in nuclear transmutation with the desired goal to reduce the volume, radiotoxicity, and storage time of spent nuclear fuel. Generation of valuable isotopes, semiconductor production, and radioisotopes are also of interest to this RFI. Consistent with the agency’s mission, ARPA-E is seeking novel and disruptive technologies that are early in the R&D cycle. ARPA-E seeks to include input from the developers and end-users of such technologies, including national laboratories, universities, private industry, and the medical community. ARPA-E is particularly interested in transmutation enabling technologies, and it is specifically interested in how such technologies can improve the reliability and duty cycles of transmutation systems while reducing capital and operating costs. Understanding the economic factors that would lead to a transmutation facility are invaluable to a potential program. Reprocessing of waste may be needed for efficient transmutation. The location of this reprocessing facility, whether located at the waste generating sites, or at the transmutation location will impact the economics. Additionally, depending on the size of the transmutation facility, there may be several facilities constructed in order to reduce quantities of waste to the desired metric. Funds for the decommissioning of reactors as well as the nuclear waste fund may be available for these types of activities.
