Toroidal trolley for fusion fission cladding refueling system

Abstract

The invention discloses a toroidal trolley for a fusion fission cladding refueling system. The toroidal trolley comprises an E-shaped frame body, hydraulic cylinders and rolling wheel sets. The framebody is fan-shaped, at least two rows of rolling wheel sets capable of moving in the same direction are mounted at the bottom of the frame body, and at least two rows of hydraulic cylinders are mounted on the top surface of the frame body. The toroidal trolley can facilitate transport of a fusion fission cladding module and refuel the fusion fission cladding system.

Description

technical field [0001] The invention relates to the technical field of nuclear fusion and fission reactor equipment, in particular to a hoop trolley used for a fusion and fission cladding refueling system. Background technique [0002] Research on fusion-fission hybrid reactors began in the 1950s with the initial idea of ​​using fusion neutrons to multiply fissile nuclides (239Pu, 233U) from fissile nuclides (238U, 232Th) and amplify fusion energy in the process output. In the 1970s and 1980s, the United States, Japan, and Turkey conducted a lot of research work on hybrid reactors. Fusion drive methods include magnetic mirrors, tokamak magnetic confinement, and laser inertial confinement. Fissile uranium / thorium cladding, but neither goes beyond simple conceptual studies. Since the late 1990s, the main purpose of American hybrid reactor research is to deal with nuclear waste from fission reactors, such as the subcritical fast transmutation reactor driven by the tokamak pro...

In the 1970s and 1980s, the United States, Japan, and Turkey conducted a lot of research work on hybrid reactors. Fusion drive methods include magnetic mirrors, tokamak magnetic confinement, and laser inertial confinement. fissile uranium / thorium cladding, but neither goes beyond simple conceptual studies

The cladding is composed of many miniature pressure shells and welded, which makes the assembly workload very large and the reliability is reduced; the manifold of the entire cladding is complex, the flow resistance is large, and the heat exchange efficiency is low; the refueling operation of the cladding module is also difficult. It is very complicated. Due to the large number of modules, the overall refueling time increases. If there are structural or functional defects in some modules, all modules need to be checked one by one, which increases the difficulty of refueling. Other mixed stack critical cladding refueling systems and methods have above disadvantages
