The Reduced Enrichment for Research and Test Reactors (RERTR) Program develops technology necessary to enable the conversion of civilian facilities using high enriched uranium (HEU) to low enriched uranium (LEU) fuels and targets. The RERTR Program was initiated by the U.S. Department of Energy in 1978. During the Program's existence, over 40 research reactors have been converted from HEU (= or >20% U-235) to LEU (< 20% U-235) fuels, and processes have been developed for producing radioisotopes with LEU targets. The RERTR Program is managed by the Office of Nuclear Material Threat Reduction in the National Nuclear Security Administration (NNSA). The main technology components of the program are:
- Currently-Qualified Fuels
- Advanced Fuel Development
- Foreign Research Reactor Spent Nuclear Fuel
- IAEA/USA Interregional Training Course
on Technical and Administrative Preparations Required for Shipment of Research Reactor Spent Fuel to Its Country of Origin - January 1997
