Problems solved by technology

[0004] However, for a single-pool reactor, the coolant load is much higher than that of a loop reactor; at the same time, the distance between the main coolant circulation equipment and the core is close, and the radiation exposure is high, which increases the damage rate of the equipment.

Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] Such as figure 1 As shown, the multi-pool reactor is mainly composed of a main vessel 1, an auxiliary vessel 2, connecting pipes 3, a core 4, a steam generator 5, a main pump 6, and a neutron shield 7. Wherein, the reactor core 4 is located in the main vessel 1 and provides a heat source for the reactor, and the connecting pipe 3 runs through the structural wall (i.e. the neutron shield 7) between the main vessel 1 and the auxiliary vessel 2, and connects the reactor core 4 and the steam generator 5 and the coolant between the main pump 6 and the core.

[0030] According to the multi-pool reactor of the present invention, the main container provides support and containment for the core...

Abstract

The invention discloses a multi-pond type reactor. The reactor comprises a main container, an attached container, a connecting pipeline, a reactor core, a steam generator, a main pump and a neutron shielding body, wherein the main container is used for providing support and containing for the reactor core and the cooling agent thereof; the attached container is used for providing the support and the containing for the steam generator and the main pump and the cooling agent thereof; the main container is communicated with the attached container through the connecting pipeline; the neutron shielding body is installed between the main container and the attached container so as to provide the shielding for the steam generator and the main pump. The reactor disclosed by the invention has the advantages of being less in cooling agent loading quantity and simple in boundary, and the main circulating equipment in the reactor bears the low irradiation strength.

Description

technical field [0001] The invention relates to the technical field of nuclear energy engineering, in particular to a reactor with a multi-pool structure. Background technique [0002] Conventional pressurized water reactors use pipe connections between the pressure vessel and the main circuit equipment such as pumps and steam generators. The pipe connection is prone to damage, and there is a risk of coolant leakage. [0003] At the same time, the boundary of the reactor coolant circuit connected by conventional pipes is complicated, which is not conducive to the demand for thermal insulation and heating of the entire primary circuit. In the fourth-generation reactors, the pool reactors used in various reactor types contain all the equipment of the primary cycle in the reactor vessel, thereby eliminating the possibility of groove accidents outside the vessel. [0004] However, for a single-pool reactor, the coolant load is much higher than that of a loop reactor; at the sa...
