In the design of nuclear reactors, such as ADS, HTGRs and fusion reactors, graphite is among the primary candidate materials for a reflector zone to soften the neutron spectrum. Moreover, the accurate prediction of tritium breeding ratio and nuclear heating rate sets the necessity of using adequate nuclear data for carbon since they have strong influence on the feasibility of the overall design of fusion reactors.展开更多
