Example Embodiment
[0071] Example 1
[0072] (1) Core structure
[0073] Such as figure 1 and figure 2 In the core structure shown, the active zone 1 of the core structure is provided with an inlet at the bottom and an outlet at the top. The density of the fuel balls in the active zone 1 is less than the density of the molten salt in the active zone 1. The fuel load capacity that can be accommodated in Zone 1 is greater than the preset fuel load capacity for operating days at full power.
[0074] The above-mentioned core structure also includes graphite balls with the same size and density as the fuel balls; the fuel balls, graphite balls and molten salt enter the active zone 1 through the inlet. The fuel ball, graphite ball and molten salt are discharged from the active zone 1 through the discharge port.
[0075] In the above core structure, the molten salt in the molten salt pebble bed reactor is fluorine salt, and the fluorine salt is 2LiF-BeF 2 Molten salt, 2LiF-BeF 2 Molten salt consists of LiF a...

[0120] (2) The molten salt pebble bed stack is the same as Example 1
[0121] (3) Fuel management and core loading method
[0122] Such as image 3 The fuel management and core loading method of the molten salt pebble bed reactor shown, the fuel management and core loading method are in the molten salt pebble bed reactor (such as figure 1 with figure 2 Shown);
[0123] The fuel management and core loading method includes the following steps:
[0124] S1: Load fuel balls into the active zone 1; where the fuel balls are loaded with a fuel load equal to the preset number of days of full power operation;
[0125] S2: According to the critical extrapolation experiment, check whether the core reaches the preset initial backup reactivity;
[0126] After detection, it is found that the preset initial backup reactivity has been reached, and then it is judged whether the active area 1 is full;
[0127] S3. Perform the follow...

[0135] (1) Core structure
[0136] Such as 1 and figure 2 In the core structure shown, the active zone 1 of the core structure is provided with an inlet at the bottom and an outlet at the top. The density of the fuel balls in the active zone 1 is less than the density of the molten salt in the active zone 1. The fuel load capacity that can be accommodated in Zone 1 is greater than the preset fuel load capacity for operating days at full power.
[0137] The above-mentioned core structure also includes graphite balls with the same size and density as the fuel balls; the fuel balls, graphite balls and molten salt enter the active zone 1 through the inlet. The fuel ball, graphite ball and molten salt are discharged from the active zone 1 through the discharge port.
[0138] In the above core structure, the molten salt in the molten salt pebble bed reactor is fluorine salt, and the fluorine salt is 2LiF-BeF 2 Molten salt, 2LiF-BeF 2 Molten salt consists of LiF and BeF ...
