RERTR FUEL TESTS  As part of the advanced fuel development program for RERTR, fuel samples are being tested in Department of Energy's Advanced Test Reactor at Idaho National Laboratory.

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, more than 70 research reactors have been converted from HEU (= or >20% U-235) to LEU (< 20% U-235) fuels, nearly 30 additional reactors that used HEU have been verified as shutdown, and processes have been developed for producing radioisotopes with LEU targets. The RERTR Program is managed by the Office of Material Management and Minimization in the National Nuclear Security Administration (NNSA). The main technology components of the program are:

  1. the development of advanced LEU fuels,
  2. design and safety analysis for research reactor conversion, and
  3. development of targets and processes for the production of the medical isotope Molybdenum-99 with LEU.

Mission Statement

The RERTR program mission supports the minimization and, to the extent possible, elimination of the use of HEU in civil nuclear applications by working to convert research reactors and radioisotope production processes to the use of LEU fuel and targets throughout the world.

2022 RERTR Meeting

The 2022 RERTR International Meeting (RERTR-2022) will be held October 2-5, 2022 in Vienna, Austria.
