This invention provides a method for evaluating the properties of fuel debris containing a mixture of nuclear fuels with varying burnup levels. [Solution] The evaluation method includes the step of calculating the fissile material ratio indicating the properties of the fuel debris based on the evaluated values ​​of the Cm-244 count rate and the amount of fissile material of the fuel debris, data showing the correlation between the ratio of the Cm-244 count rate and the amount of fissile material and the fissile material ratio, and / or the evaluated values ​​of the Eu-154 count rate and the amount of fissile material of the fuel debris, data showing the correlation between the ratio of the Eu-154 count rate and the amount of fissile material and the fissile material ratio.

This application provides a hybrid nuclear energy system, including a fusion core adapted to radiate fusion products; a blanket device surrounding the fusion core to receive fusion products, the blanket device being adapted to contain blanket material, including fissile material; a fuel loop connected to the blanket device, the blanket material being adapted to circulate within the blanket device and the fuel loop; a heat exchange module adapted to contain heat exchange material, at least a portion of the fuel loop being located within the heat exchange module or the heat exchange module being at least partially located within the blanket device; and a cooling loop connected to the heat exchange module, the heat exchange material circulating within the heat exchange module and the cooling loop and exchanging heat with the blanket material. This application provides a hybrid nuclear energy system that can improve the system's energy gain factor and has stronger reliability and safety.
