- Abstract:
- Nuclear research reactors are used in many countries for many different purposes. Most of the reactors are used for research (mainly in physics), training for nuclear operators and engineers, materials testing in radiation conditions, or the production of radioiso¬topes for medicine and industry. Some countries, like Iran, are building new reactors ostensibly to fill these needs. Many of these reactors operate with highly enriched uranium (HEU) nuclear fuel — in most cases, enriched to around 90 percent, the same as fuel for nuclear weapons. The production and fabrication of HEU fuel, and the handling, transport, and storage of both fresh and spent fuel containing HEU entails considerable proliferation, security, and safety risks as well as very high costs. The global stockpile of highly enriched uranium was about 1500 tons in 2012, which was enough for more than 60,000 simple, first gen¬eration implosion weapons. About 98 percent of this material is held by the nuclear weapon states, with the largest HEU stockpiles in Russia and the United States.
