The Global Distribution of Civilian Highly Enriched Uranium (HEU)


During the 1950s and 1960s, as part of their competing Atoms for Peace programs, the United States and the Soviet Union built hundreds of research reactors domestically and for export to more than 40 other countries. In response to demands for longer-lived fuel and maximum reactor performance, export restrictions on fissile materials were relaxed and most of these reactors shifted to fuel containing weapon-grade HEU.

As a result, HEU is still used today as a research-reactor fuel in about 140 civilian reactors worldwide. In addition, HEU often remains at sites of shut down, but not yet decommissioned reactors. Taken together, the global inventory of civilian HEU reactor fuel is very roughly 50 metric tons, widely distributed around the globe. According to a U.S. Government study, in 2004 there were around the world at least 128 sites associated with research reactors with at least 20 kilograms of HEU.

Since 1978, an international effort has been directed at converting HEU-fueled reactors to low-enriched fuel in the Reduced Enrichment for Research and Test Reactor (RERTR) program. Almost all new reactors designed since that time use LEU fuel. By the end of 2005, the RERTR program had converted or partially converted 42 research reactors. The world's remaining research reactors consume about 1,000 kilograms of HEU per year -- virtually all supplied by the United States and Russia. RERTR program analysts believe that 41 more reactors can be converted using existing LEU fuels.

A new fuel is now under development, which -- if successfully qualified -- would enable conversion of virtually all remaining HEU-fueled reactors worldwide. The main technical obstacle for a global HEU cleanout would be removed.
