DE-FOA-0003623: High-performance Optimized Recycled Nuclear Isotopes for Gen IV reactors (HORNIG)

About this opportunity

NOFO Modification 01 posted and Encourage/Discourage letters sent July 7, 2026.This funding opportunity supports the development of transuranic (TRU) fuels from a largely untapped, domestic fissile resource found across U.S. inventories. TRU fuels could expand the nation’s nuclear fuel supply while reducing the volume of radioactive waste. Establishing TRU fuels as an economic source of energy will bolster American industry, energy dominance, and national security by:Strengthening fuel supply chains for nuclear reactorsReducing reliance on foreign sourcesAdvancing American leadership in critical technologiesSupporting long-term deployment of new nuclear power plantsHigh-performance Optimized Recycled Nuclear Isotopes for Gen IV reactors (HORNIG) will fund coordinated research and developme...
