Abstract

The invention discloses a shell-and-tube lead base alloy cooling reactor. The reactor comprises a reactor vessel, a reactor core, fuel channels and pressure pipes, wherein each fuel channel is formed by placing a nuclear fuel assembly and a lead base alloy coolant into one pressure pipe, and multiple fuel channels ate placed in a reactor vessel pool to form the reactor core. The reactor is applied the design requirement background of large lead base alloy cooling reactors, so that a reactor system has the characteristics of high power and high inherent safety realized only by the aid of material characteristics, the reactor core meltdown probability is eliminated in design, the massive radioactive release probability is eliminated in reality, and off-site emergency is canceled; in the fuel channels formed by placing the nuclear fuel assemblies and the lead base alloy coolants into the pressure pipes, the flow of the coolant in each pressure pipe can be adjusted according to single-pipe power design of the pressure pipe.

Description

technical field [0001] The invention relates to the field of a lead-based alloy cooling reactor, in particular to a shell-and-tube type lead-based alloy cooling reactor. Background technique [0002] Lead Alloy cooled Fast Reactor (LFR) is an advanced fast reactor capable of realizing a closed fuel cycle, which can realize the efficient conversion and proliferation of uranium and thorium and the effective transmutation management of actinides. It uses lead or lead-bismuth eutectic liquid metal coolant. The most striking aspect of this technology is that the lead-based alloy has excellent nuclear, thermal and safety characteristics, and has the potential to revolutionize energy generation, transfer, conversion and inherent safety. Lead-cooled fast reactors can rely on natural circulation to form a primary loop coolant flow (low-power reactor design), and can also adopt forced circulation design. The core coolant outlet temperature can reach about 550°C (mainly considering th...
