ABSTRACT
The reduced enrichment programs for
the JRR-3M, JRR-4 and JMTR of Japan Atomic Energy Research Institute (JAERI)
have been completed. 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 (ANL).
The JRR-3M commenced using LEU
silicide fuel elements instead of LEU aluminide fuel elements in September,
1999.
The Japanese Government approved a
cancellation of the KUHFR Project in February 1991, and April 1994 the U.S.
Government gave an approval to utilize HEU fuel in the KUR instead of the
KUHFR. Therefore, the KUR will be
operated with HEU fuel until March 2004, then the full core conversion with LEU
silicide will be done. The first shipment of spent fuels since 1974 was done in
August, 1999.
