Separable core type hybrid nuclear reactor

Abstract

According to the invention, disclosed is a separable core type hybrid nuclear reactor using a single nuclear reactor, capable of a power generation operation as a normal research nuclear reactor, andalso facilitating the use as critical facilities. When the nuclear reactor is used as the critical facilities, a portion of core is separated and moved in a lateral direction to secure a space, and alattice of nuclear reactor component materials is charged in the secured space for a critical experiment, and thus a lattice characteristic experiment can be performed. According to the invention, thenuclear reactor described above comprises: a separable core type hybrid nuclear reactor (100) installed inside a concrete water tank (10); and a mode switching drive unit (20) controlling an operation mode of the hybrid nuclear reactor (100), wherein the separable core type hybrid nuclear reactor (100) comprises: a lattice structure (130) having a separable structure and installed on the bottom part of the concrete water tank (10); a reflector structure (150) having a separable structure and installed in an edge part of the lattice structure (130); and a partition structure (170) having a separable structure and installed to the top of the lattice structure (130).

Description

[0001] This application is a divisional application of an application with an application date of September 13, 2016, an application number of 2016108218526, and an invention title of "core-separated hybrid reactor". technical field [0002] The present invention relates to a core-separated hybrid reactor capable of operating a single reactor in an output operation mode or a critical test mode. In particular, it relates to a core-separated type hybrid reactor in which the core is not separated in the output operation mode, but a part of the moving core is separated in the critical test mode operation to secure a space for the critical test. Background technique [0003] In the field of atomic energy, a critical facility is generally a reactor physical experiment device that repeatedly arranges unit grids such as nuclear fuel, deceleration material, and cooling material, which are the basic elements of the reactor core, to form a critical state. It is used to understand the ar...
