Wherein the fuel group may be a collection of devices that can be powered by combustion of the fuel. The nuclear power unit may be an energy supply system consisting of at least one fuel assembly. The nuclear power unit can group the fuel groups according to the quantity to obtain at least one fuel group to be treated. The nuclear power unit may include at least one fuel assembly to be treated. The first fuel group may be a fuel group to be treated for fuel combustion at rated power. Specifically, the rated power is the maximum power that can be achieved when the fuel assembly of the nuclear power unit is subjected to combustion operation.

Specifically, the user requirements are as follows: under the condition of thermal state full power, the nuclear enthalpy heat rising pipe factor FNDeltaH is less than or equal to 1.72; under the condition of thermal state full power, the total power peak factor FQ is less than or equal to 2.60 so as to meet the LOCA accident consequence limiting requirement; when the reactor core is operated at any power level (including HZP), the temperature coefficient of the moderator cannot be positive, namely MTC is less than or equal to 0 pcm/DEG C; when the reactor core operates at any power level (including HZP), the shutdown margin (SDM) is more than or equal to 1600pcm; the maximum average burnup of the reactor core fuel rods is not more than 62000MWd/tU.

The initial power may be a preset power of initial use of the fuel group. The operating power value may be a value of power corresponding to the fuel group to be treated.
Specifically, the operation power value corresponding to each fuel group to be processed can be calculated according to the initial power, the fuel group to be processed and the power operation mode corresponding to the nuclear power unit. The fuel groups to be treated of the nuclear power unit are distributed in a circulating mode. The power of the first fuel group is unchanged and is the initial power. The power of each fuel group to be treated in the second fuel group is smaller than the power of the fuel group to be treated of the previous fuel power type by a preset value, and the power of each fuel group to be treated in the second fuel group is smaller than the power of the fuel group to be treated of the previous fuel power type by 0.8. If the fuel power type of the fuel group to be processed of the second fuel group is the non-skid power type according to the power operation mode, the power of the fuel group to be processed is the initial power. Thereby calculating the corresponding operation power value of each fuel group to be treated. And executing fuel simulation operation according to the power operation modes and the operation power values corresponding to the fuel groups to be processed, and obtaining simulation detection values corresponding to the power operation modes.
In one example, power operation mode 1 of the nuclear power unit is: the fuel power type of the fuel group 1 to be treated is a non-skid power type, the fuel power type of the fuel group 2 to be treated is a skid power type, and the fuel power type of the fuel group 3 to be treated is a skid power type. The preset initial power is 100. The operating power value of the fuel group 1 to be treated is 100. The fuel power type of the fuel group 2 to be treated is a sliding power type, the operation power value of the fuel group 2 to be treated is lower than the operation power value of the fuel group 1 to be treated by 0.8, and the operation power value of the fuel group 2 to be treated is 99.2.
