Embodiment 1

[0041] Li 4 SiO 4 Tritium breeder pellet loading and unloading

[0042] (1) Loading

[0043] Carry out vacuum treatment before loading, open the evacuation valves MV6, MV2, PV4, PV9, PV8 and the upper inlet valve of the multiplication cladding module, close the other valves, and carry out vacuum treatment on the system until the vacuum is ~1Pa, then close MV6 and vacuum pump. Then open the intake valves MV5 and PV1, fill with helium to 0.1MPa, and then close the intake valves MV5, MV2, PV1, PV4, PV9, PV8.

[0044] Weigh 10gLi 4 SiO 4 Proliferator ceramic balls, open the top cover of the charging tank, pour it into the charging tank, then close the top cover, open the evacuation valve MV6, and vacuum the charging tank until the vacuum is ~1Pa, then close MV6 and vacuum pump. Then open the intake valves MV5 and PV1, charge helium to 0.1MPa, and then close the intake valves MV5 and PV1. Open the feed valve MV2, under gravity Li 4 SiO 4 The multiplier ceramic pellets are...

Abstract

The invention discloses a reactor refueling system and an online loading, unloading and refueling method.The system is composed of a carrier gas unit, a loading device, a proliferation cladding module, an unloading device and a tail gas treatment device, and the connection relation is that the carrier gas unit is connected with the loading device and the proliferation cladding module; the multiplication cladding module is respectively connected with the loading device and the unloading device; the tail gas treatment device is respectively connected with the multiplication cladding module and the unloading device; and in the refueling process of the system, the multiplication cladding module does not get out of a pile, and a multiplication agent or a neutron multiplication agent is loaded and unloaded on line. According to the device, on-line loading and unloading of proliferation agent pellets or neutron multiplication agent pellets of the fusion reactor proliferation cladding are achieved, and the whole operation becomes simple and controllable. Meanwhile, tritium carrier band purging can also be achieved through a refueling inlet and outlet, and an inlet and an outlet of a multiplication cladding module do not need to be additionally arranged.

Description

technical field [0001] The invention belongs to the field of fusion reactor breeding cladding, and can be applied to the refueling collection system of fusion breeding cladding breeding agent pellets or neutron multiplier pellets and other places that require refueling, and specifically relates to a reactor refueling system , Online loading, unloading and refueling methods. Background technique [0002] During the operation of the fusion device, the breeder pellets or neutron multiplier pellets need to be loaded, and the breeder pellets will be taken out for unloading after a certain burn-up. The current plan is to weld the multiplication cladding module after loading the multiplication agent pellets or neutron multiplier pellets; the process of unloading is more complicated. After the first wall needs to be removed, the multiplication cladding modules will be assembled Unload after dismantling. The loading and unloading process is extremely complicated and inconvenient to...
