The reduced enrichment programs for the
JRR-3M, JRR-4 and JMTR of Japan Atomic Energy Agency (JAEA,
former name is Japan Atomic Energy Research Institute (JAERI))
has been completed by 1999. The KUR of Kyoto University
Research Reactor Institute (KURRI) has been partially
completed and is still in progress under the Joint Study
Program with Argonne National Laboratory (Argonne).
The JRR-3M using LEU silicide fuel elements has done a functional test by the Japanese Government in 2000, and the property of the reactor core was satisfied.
JAEA has established a "U-Mo fuel ad hoc committee" and has been studying the U-Mo fuel installation plan by carefully observing the development situation of the U-Mo fuel. In KURRI, the Japanese Government approved a cancellation of the Kyoto University High Flux Reactor (KUHFR) Project in February, 1991, and in April, 1994 the U.S. Government gave an approval to utilize HEU fuel in the KUR instead of the KUHFR. Therefore, the KUR was able to operate with HEU fuel until February 2006. After a cooling time of approximately one year, all HEU KUR spent fuel elements will be sent to the U.S. by March 2008. Licensing for the full core conversion of KUR to LEU fuel is under progress and the core conversion will be completed in 2008.
