Molten salt reactor loading and unloading system

Abstract

The invention discloses a molten salt reactor loading and unloading system, comprising at least one base salt tank, at least one feed salt tank, a reactor tank and a first heat exchanger, wherein theouter wall face of the reactor tank is provided with a base salt inlet, a fuel salt inlet and a fuel salt outlet; the base salt tank is connected with the base salt inlet and is communicated with thereactor tank; the feed salt tank is connected with the reactor tank and is communicated with the reactor tank; the fuel salt outlet and the fuel salt inlet are respectively connected with an inlet andan outlet of the first heat exchanger; a fuel salt loop is formed by the reactor tank and the first heat exchanger. According to the molten salt reactor loading and unloading system, the base salt tank and the feed salt tank can be used for respectively adding base salt and feed salt into the reactor tank, and the base salt and the feed salt in the fuel salt loop can be evenly mixed by means of the operation of the fuel salt loop; the uniform mixing is rapid and convenient, the operation is simple, and the cost is low.

Description

technical field [0001] The invention relates to a molten salt heap loading and unloading system. Background technique [0002] At the Generation IV International Forum (GIF), world-renowned nuclear energy system experts reached a consensus on the technical direction of the fourth-generation reactor type, and selected six candidate reactor types for the fourth-generation reactor. Its goal is to reach the level of commercialization in 2030. Its main features are high economy, good safety, less nuclear waste generation, and the ability to prevent nuclear proliferation. Among the six candidate reactor types of the fourth generation reactor, the molten salt reactor is the only liquid fuel reactor. Fuel salt can adopt molten state fluorine salt (such as LiF-BeF 2 -ZrF 4 -UF 4 、LiF-BeF 2 -UF 4 -ThF 4 , NaF-ZrF 4 -UF 4 etc.), molten chloride salts (such as UCl 4 -UCl 3 -NaCl, NaCl-UCl 3 , NaCl-UCl 4 ) or other molten salts in molten state (such as UCl 3 F, etc.). In t...
