Apparatus for treating molten atomic reactor fuel rod using vertical cavity

Abstract

The present invention relates to an apparatus for blocking or minimizing radiation leakage by automatically treating molten fuel rods, without power or human effort, when a major accident occurs due to a malfunction of an atomic reactor that leads to melting / damaging of fuel rod containers inside the atomic reactor after the fuel rods, which are used in the atomic reactor, become molten.

Description

technical field [0001] The present invention generally relates to an apparatus for automatically disposing of molten fuel rods when due to natural disasters or abnormal operation of a nuclear reactor (which causes loss of the core cooling function of the nuclear reactor, melting of the fuel rods of the nuclear reactor, damage to the reactor containment vessel, and In the event of a serious accident due to external discharge of molten fuel rods), the device prevents or minimizes radiation leakage without the use of machines or human labor. Background technique [0002] Nuclear power plants are generally divided into nuclear reactor-based nuclear steam supply systems, turbine / generator systems that operate generators through steam supply, and other secondary facilities. Here, a nuclear reactor controls a large amount of energy that is progressively produced when a nuclear reaction occurs, thereby functioning to allow nuclear energy to be converted into electrical energy.

AI Technical Summary

Problems solved by technology

The cooling equipment has the problem that the high temperature molten fuel rods and the coolant directly react with each other in the closed space, thereby causing the sudden generation of steam, which causes the possibility of steam explosion

Cooling equipment has limitations on the amount of cooling allowed and can be used for vapor diffusion phenomena causing secondary problems
