Agency Overview: The Advanced Research Projects Agency Energy (ARPA-E), an organization within the Department of Energy (DOE), is chartered by Congress in the America COMPETES Act of 2007 (P.L. 110-69), as amended by the America COMPETES Reauthorization Act of 2010 (P.L. 111-358), as further amended by the Energy Act of 2020 (P.L. 116-260): (A) to enhance the economic and energy security of the United States through the development of energy technologies that (i) reduce imports of energy from foreign sources; (ii) reduce energy-related emissions, including greenhouse gases; (iii) improve the energy efficiency of all economic sectors; (iv) provide transformative solutions to improve the management, clean-up, and disposal of radioactive waste and spent nuclear fuel; and (v) improve the resilience, reliability, and security of infrastructure to produce, deliver, and store energy; and (B) to ensure that the United States maintains a technological lead in developing and deploying advanced energy technologies. ARPA-E issues this Funding Opportunity Announcement (FOA) under its authorizing statute codified at 42 U.S.C. 16538. The FOA and any cooperative agreements or grants made under this FOA are subject to 2 C.F.R. Part 200 as supplemented by 2 C.F.R. Part 910. ARPA-E funds research on, and the development of, transformative science and technology solutions to address the energy and environmental missions of the Department. The agency focuses on technologies that can be meaningfully advanced with a modest investment over a defined period of time in order to catalyze the translation from scientific discovery to early-stage technology. For the latest news and information about ARPA-E, its programs and the research projects currently supported, see: http://arpa-e.energy.gov/. ARPA-E funds transformational research. Existing energy technologies generally progress on established learning curves where refinements to a technology and the economies of scale that accrue as manufacturing and distribution develop drive improvements to the cost/performance metric in a gradual fashion. This continual improvement of a technology is important to its increased commercial deployment and is appropriately the focus of the private sector or the applied technology offices within DOE. In contrast, ARPA-E supports transformative research that has the potential to create fundamentally new learning curves. ARPA-E technology projects typically start with cost/performance estimates well above the level of an incumbent technology. Given the high risk inherent in these projects, many will fail to progress, but some may succeed in generating a new learning curve with a projected cost/performance metric that is significantly better than that of the incumbent technology. ARPA-E funds technology with the potential to be disruptive in the marketplace. The mere creation of a new learning curve does not ensure market penetration. Rather, the ultimate value of a technology is determined by the marketplace, and impactful technologies ultimately become disruptive that is, they are widely adopted and displace existing technologies from the marketplace or create entirely new markets. ARPA-E understands that definitive proof of market disruption takes time, particularly for energy technologies. Therefore, ARPA-E funds the development of technologies that, if technically successful, have clear disruptive potential, e.g., by demonstrating capability for manufacturing at competitive cost and deployment at scale. ARPA-E funds applied research and development. The Office of Management and Budget defines applied research as an original investigation undertaken in order to acquire new knowledge...directed primarily towards a specific practical aim or objective and defines experimental development as creative and systematic work, drawing on knowledge gained from research and practical experience, which is directed at producing new products or processes or improving existing products or processes. Applicants interested in receiving financial assistance for basic research (defined by the Office of Management and Budget as experimental or theoretical work undertaken primarily to acquire new knowledge of the underlying foundations of phenomena and observable facts )1 should contact the DOE's Office of Science (http://science.energy.gov/). Office of Science national scientific user facilities (http://science.energy.gov/user-facilities/) are open to all researchers, including ARPA-E Applicants and awardees. These facilities provide advanced tools of modern science including accelerators, colliders, supercomputers, light sources and neutron sources, as well as facilities for studying the nanoworld, the environment, and the atmosphere. Projects focused on early-stage R&D for the improvement of technology along defined roadmaps may be more appropriate for support through the DOE applied energy offices including: the Office of Energy Efficiency and Renewable Energy (http://www.eere.energy.gov/), the Office of Fossil Energy and Carbon Management (https://www.energy.gov/fecm/office-fossil-energy-and-carbon-management), the Office of Nuclear Energy (http://www.energy.gov/ne/office-nuclear-energy), and the Office of Electricity (https://www.energy.gov/oe/office-electricity). Program Overview: The Nuclear Energy Waste Transmutation Optimized Now (NEWTON) program will support the research and development of technologies that enable the transmutation of used nuclear fuel (UNF) to alleviate the impact of storage in permanent disposal facilities. This program seeks to fund the development of novel technologies that increase the overall capacity factor, power output, and efficiency of particle generation systems (including but not limited to proton, neutron, and/or photon), by reducing beam trip magnitude and duration (referred to as loss of beam). Additional technologies will focus on increasing the throughput of transmutation by developing target materials that maximize transmutation rates and are easily processible to remove the transmuted material. The United States does not currently have an active facility for the permanent disposal of used nuclear fuel derived from the civilian nuclear sector. Used nuclear fuel comprises several classes of isotopes that could be processed in different ways due to their economic value. Firstly, uranium (U), which comprises greater than 95% of the mass of UNF, can be reprocessed and converted back into fuel for light-water reactors through the addition of small amounts of uranium-235 (U-235). Secondly, plutonium (Pu) and minor actinides (MAs), such as neptunium (Np), americium (Am), and curium (Cm), which together comprise roughly 1.5% of UNF by mass, are produced from nuclear fission. Many of these isotopes are fissionable and could be incorporated into fuels designed for advanced reactor concepts. Intermediate-lived fission products (ILFPs) including strontium-90 (Sr-90) and caesium-137 (Cs-137) have relatively short half-lives of roughly 30 years and have applications in radioisotope thermoelectric generators for space applications. However, ILFPs are largely destined for permanent disposal in a deep geological repository. The major long-lived fission products (LLFPs) have half-lives exceeding 200,000 years and have few commercial applications. LLFPS include selenium-79 (Se-79), technetium-99 (Tc-99), tin-126 (Sn-126), iodine-129 (I-129), and caesium-135 (Cs-135). The last class of isotopes are the stable isotopes produced from nuclear fission and resulting decay. These isotopes could be extracted from UNF, but no commercial processing of these have been undertaken. A deep geological disposal facility for the disposition of UNF in the U.S. has been estimated to cost $96.18 billion over the 150-year lifetime, after which the facility would cease to accept new waste. This facility would be able to store 70,000 metric tons (MT) of unprocessed UNF, which is insufficient for the existing volume of civilian waste. Densification of the waste can be accomplished through removal of the plutonium, minor actinides, and ILFP components of the UNF. Removal of 99.9% of these components would allow a densification factor of 225, based on current disposal requirements, thus allowing a single repository to store upwards of approximately 16 million MT of UNF. The LLFPs are responsible for many of the engineered barriers that are required to be built in the repository due to their long half-lives and environmental mobility. Removal of these LLFPs could decrease the capital expenditure of a permanent geological repository while also improving safety.
