Hybrid nuclear reactor with separable core

Abstract

The present invention provides a core separation type hybrid reactor capable of realizing the same output operation as a conventional reactor with a single reactor or as a critical facility. When used as a critical facility, a grid of the reactor constituent material is loaded in a space for a portion of the separation core that is laterally moved to form a critical test space therebetween, thereby performing a grid characteristic experiment. The reactor includes a core separation type mixed reactor 100 provided inside the concrete water tank 10, and a mode switching driving section 20 for adjusting the operation mode of the hybrid reactor 100, and the core separation type mixed reactor 100, comprising: a lattice structure 130 of a separate structure disposed on a bottom surface portion of the concrete water tank 10; a reflector structure 150 of a separate type structure disposed at an edge portion of the grid structure 130; and a type partition wall structure 170 in which the reflector structure 150 is surrounded by an upper portion of the grid structure 130.

Description

Technical field [0001] The present invention relates to a core separation type hybrid reactor capable of operating a single reactor in an output operation mode or a critical experiment mode. In particular, it relates to a core-separated hybrid reactor that operates without separating the core in the output operation mode, but separates a part of the mobile core when operating in the critical experiment mode to ensure a critical experimental space. Background technique [0002] In the field of atomic energy, a critical facility is generally a reactor physics experimental device that repeatedly arranges nuclear fuel, deceleration materials, and cooling materials as the basic elements of the reactor core to form a critical state. It is used to understand the arrangement of objects through experiments. Nuclear characteristics. For the purpose, the arrangement needs to be easily changed as needed, and the heat output needs to be as low as possible. The critical facility is widely us...
