Embodiment Construction

[0023] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings so as to be easily implemented by those skilled in the art.

[0024] figure 2 The overall structure of an apparatus for processing molten fuel rods of a nuclear reactor according to an embodiment of the present invention is shown. Such as figure 2 As shown in , in the apparatus of the present invention, an enclosed building 3 is formed around the reactor containment vessel 1 , and the primary barrier 1 and the secondary barrier 4 are installed in the enclosed building 3 . The main barrier 2 is supported by a substrate 8 .

[0025] An opening is formed at the bottom of the main spacer 2 , and a long vertical cavity 11 for embedding molten fuel rods is formed in the base plate 8 supporting the main spacer 2 .

[0026] Because the vertical cavity 11 is formed up to the underground bedrock, the fuel rods 6 fall from the reactor containment vessel 1 ...

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.
