Embodiment Construction

[0045] The present application is based on a very compact form of the tokamak and employs a series of innovative features, including the optimization of the alpha confinement at unexpectedly low plasma currents. The aim of the "Efficient Compact Fusion Reactor" (ECFR) is to provide a compact fusion power plant.

[0046] When a deuterium-tritium (D-T) or deuterium-deuterium (D-D) plasma becomes very hot, atomic nuclei fuse together, producing fusion neutrons and releasing high-energy neutrons. So far, the most promising way to achieve this goal is to use a tokamak; in polymerization using traditional tokamak methods (as implemented by ITER), the plasma needs to have high confinement time, high temperature and High density to optimize this process.

[0047] Tokamak is based on a strong circular magnetic field B T and high plasma current I P is characterized by the combination of a large plasma volume and significant auxiliary heating to provide a thermally stable plasma that ...

Abstract

An efficient compact nuclear fusion reactor for use as a neutron source or energy source is described. The reactor comprises a toroidal plasma chamber and a plasma confinement system arranged to generate a magnetic field for confining a plasma in the chamber. The plasma confinement system is configured so that a major radius of the confined plasma is 1.5m or less. The toroidal magnetic field is operated 5T or less and the plasma current is 5 MA or less. Despite this, [Alpha]-particles generated are confined in the plasma.

Description

technical field [0001] The invention relates to a compact fusion reactor operating in a strong annular field. In particular, but not exclusively, the invention relates to a spherical tokamak reactor suitable for use as an energy source or as a high-efficiency neutron source. Background technique [0002] The challenges of producing fusion energy are complex. Many alternatives to tokamaks have been proposed, although none have yet produced results comparable to the best tokamaks currently in operation, such as JET. [0003] After starting the construction of ITER, the largest and most expensive (c15bn euro) tokamak in history, the world's nuclear fusion research has entered a new stage. A successful route to commercial fusion reactors requires long pulses, high efficiencies that make electricity generation economical, and stable operation. These three conditions are particularly difficult to achieve simultaneously, and the planned scenario would require years of experiment...
