Abstract

The invention discloses a shell-and-tube type lead-based alloy cooling reactor, which includes a reactor container, a core, a fuel channel and a pressure tube, and the fuel channel formed by placing a nuclear fuel assembly and a lead-based alloy coolant in the pressure tube, and several The fuel channels are put into the reactor vessel pool to form the core. Applied to the background of large-scale lead-based alloy cooling reactor design requirements, the reactor system has high power characteristics and high inherent safety achieved only by material characteristics, and eliminates the probability of core melting and large-scale radioactive release from the design. Off-site emergency is canceled; the nuclear fuel assembly and the lead-bismuth coolant are placed in the fuel channel formed by the pressure tube, and the coolant flow rate in each pressure tube can be adjusted according to its single-tube power design.

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...
