Description

technical field [0001] The invention belongs to the technical field of reactor system component design, and in particular relates to a multifunctional internal heat separation system for a liquid metal cooling pool type reactor. Background technique [0002] The liquid metal cooling pool reactor adopts an integrated design, and all reactor components are immersed in the liquid metal in the main container, which effectively reduces the probability of loss of primary coolant accident (LOCA); the main container is loaded with a large amount of liquid metal , so that the reactor has good thermal inertia; liquid metal has good neutron performance, and can be designed as a breeder fast reactor. These advantages make the liquid metal-cooled pool reactor have good inherent safety and economy, and it is one of the important candidate types of advanced reactors. [0003] In-core thermal separation system is one of the important systems of liquid metal cooling pool reactor. The heat ...
