The Japan materials testing reactor (JMTR) is a 50-MW light-water-moderated and -cooled tank-type reactor using engineering test reactor-type fuel. Core conversion from medium-enrichment uranium (MEU) aluminide fuel to low-enrichment uranium (LEU) silicide fuel of the JMTR is scheduled for 1993. The LEU silicide fuel element at 4.8 g U/cm[sup 3] with cadmium wires in the sideplates as burnable absorbers has been selected to achieve upgraded fuel cycle performance of extended cycle length and reduced control rod movement during operation. Shows a comparison of the LEU and the MEU fuel specifications is presented. A neutronic calculation method was developed for the LEU fuel because of adopting the strongly absorbing cadmium wires in the sideplates.
