Structure and Specifications of Fuel Assembly |
||
The fuel assembly consists of 28 fuel rods and has cylindrical structure for the insertion into a pressure tube. Fugen uses MOX fuel along with enriched uranium fuel. Although Fugen used fuels with relatively small quantity of fissile material, 1.4% to 1.5% (assembly average) in the initial operation, it uses 1.9% to 2.0% fissile fuels at present, from the aspect of the economical efficiency of the nuclear fuel cycle. In addition, the test MOX fuel assemblies, consist of 36 fuel rods, have been irradiated as a part of the fuel development of the ATR demonstration plant. The burnup of those test fuel assemblies increased with higher plutonium content, 2.4% to 3.5% fissile material (assembly's average), compared with Fugen's standard fuel assemblies. |
