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:
|
Fuels for Research and Test Reactors
- 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
Design and Safety Analyses for Research and Test Reactors
Radioisotope Production

The U.S. Department of Energy / National Nuclear Security Administration’s Office of Global Threat Reduction in cooperation with the International Atomic Energy Agency hosted the “RERTR 2011 International Meeting on Reduced Enrichment for Research and Test Reactors.” The meeting was being organized by Argonne National Laboratory, Chilean Nuclear Energy Commission (CCHEN) and Idaho National Laboratory and was held in Santiago, Chile from October 23-27, 2011. This was the 33rd annual meeting in a series on the same general subject regarding conversion of reactors within the Global Threat Reduction Initiative. RERTR-2011 related resources:
