Material changing system and accelerator driving subcritical reactor with material changing system

Abstract

The embodiment of the invention provides a material changing system for an accelerator driving subcritical reactor and the accelerator driving subcritical reactor with the material changing system. The material changing system comprises a rotatable rotating plug (2) and a material changing machine (1), wherein the rotating plug (2) is arranged on a top cover of a reactor; the material changing machine (1) comprises a rotating rod (8), a cantilever (7) and a material changing grasping head (6); the cantilever (7) is connected with the lower end of the rotating rod (8); the material changing grasping head (6) is connected with the end part, far away from the rotating rod (8), of the cantilever (7); the rotating rod (8) is arranged on the rotating plug (2), can rotate around the self axial line and can vertically move. The material changing system according to the embodiment of the invention has the advantages that the structure is simple and compact; the material changing operation is simple and convenient after the material changing system according to the embodiment of the invention is used.

Description

technical field [0001] Embodiments of the present invention relate to a refueling system for an accelerator-driven subcritical reactor and an accelerator-driven subcritical reactor with the refueling system. Background technique [0002] The Accelerator Driven Sub-critical System (ADS for short) is mainly composed of an accelerator, a heavy nuclear spallation target and a subcritical reactor. , to generate broad-spectrum, medium-to-high-flux neutrons as an external source to drive the fissile material in the subcritical reactor to undergo a continuous chain reaction, so that the long-lived highly reflective nuclides eventually become non-radioactive or short-lived radionuclides , and maintaining the operation of the reactor is one of the effective technical means to improve the utilization rate of nuclear fuel and reduce the geological accumulation of high-level radioactive waste. The subcritical reactor is an important part of the ADS system, and its coolant is the liquid ...

Problems solved by technology

The small cocks are generally installed on the large cocks and arranged eccentrically. Since the small cocks need to be swept around for refueling, the size of the large cocks is larger than the size of the core, so that the refueling system takes up a lot of space on the top of the reactor, which is not conducive to the compactness of the reactor. design
