Abstract

The invention relates to a concentric spherical surface separation plate type spherical main container, and belongs to the technical field of molten salt reactors. With the molten salt depleted uranium reactor formed from the concentric spherical surface separation plate type spherical main container, the difficult problem of the purification of the fission product inside the spherical main container can be solved, the fission product purification system is not required, the burning mode that the direct input of the depleted uranium and the direct output of the spent fuel are performed on the reactor is achieved, the low-cost long-term safe and stable operating is achieved, and all the excellent performances of the molten salt depleted uranium reactor can be maintained. According to the present invention, the space is divided into the thin sheet by using the multi-layer concentric spherical surface thin separation plate having the material inlet and the material outlet, or the space is divided into the tubular channels by additionally using the radial thin separation plate, valves and the like are arranged on the material inlet, the material outlet and the channel to control the molten salt flowing mode, the internal separation plate uses the modes such as module design, non-welded stacking installation of various modules, and whole replacement of the module, the top portion is provided with the openable cover plate system, and the innermost layer, the outermost layer and the required middle layer are provided with the corresponding channels connected to the corresponding control device and other devices outside the reactor core; and the concentric spherical surface separation plate type spherical main container is mainly used as the neutron source and the small energy source.

Description

technical field [0001] The invention relates to a main container of a molten salt reactor, especially a spherical main container of a molten salt depleted uranium reactor capable of safe operation and nuclear fuel self-breeding and self-sufficiency, mainly used as a neutron source, and also used as a small-scale energy application. Background technique [0002] There are many types of neutron sources, mainly radionuclide neutron sources, accelerator neutron sources and reactor neutron sources. Although each has different functions and uses, such as radiation production of medical radioactive isotopes, neutron activation analysis, neutron scattering, etc., and scientific and technological research, the cost of operation, use and acquisition of neutrons is relatively high. Therefore, it is very necessary to develop a neutron source that can not only operate safely but also make the cost of operation and use very low in practical applications.

Problems solved by technology

[0007] In order to overcome the risk of supercritical accidents in existing thermal neutron reactors and sodium-cooled fast reactors, the utilization rate of uranium resources in thermal neutron reactors is very low, and many difficulties brought about by the chemical activity of sodium in sodium-cooled fast reactors , and as a neutron source, its operation, use and neutron acquisition costs are relatively high. The present invention provides a concentric spherical clapboard-type spherical main container suitable for molten salt depleted uranium reactors, which can constitute molten salt depleted uranium reactors. The reactor neutron source can also be used as a small energy reactor. This reactor can not only completely eliminate the risk of supercritical accidents, greatly improve the utilization rate of uranium resources, and realize high burnup of depleted uranium without purification system, but also enable The cost of operating, using and obtaining neutrons of this type of molten salt depleted uranium reactor neutron source is very low
