Description

This funding opportunity from the Advanced Research Projects Agency - Energy (ARPA-E) supports research and development projects focused on creating commercially deployable transuranic (TRU) fuel technologies. The program aims to strengthen U.S. energy security, reduce nuclear waste, and enable long-term energy deployment by developing a domestic TRU fuel supply chain with a target levelized cost of fuel of 1¢/kWh. Projects should include a credible path to fuel qualification and regulatory acceptance within seven years. The program encourages innovative approaches to expand U.S. fuel supply options and support a closed fuel cycle.
