AL_A moves forward on world’s first magnetized fusion power plant in UK

2023-01-16T12:06:00-05:00

AL_A has been granted permission to construct the world’s first magnetized fusion power plant. The Culham Science Centre facility, to be located in Oxford, UK, is anchored by a 125-foot-tall cylindrical fusion hall wrapped in a translucent facade.

The scheme was first unveiled in August 2021, commissioned by the Canadian energy company General Fusion in collaboration with the UK Atomic Energy Authority.

Unlike traditional nuclear fission stations, which generate energy by splitting atoms, the fusion process involves merging two atoms to generate vast amounts of energy without the highly radioactive waste associated with nuclear fission. Last month, US scientists announced a major breakthrough in the process through a fusion experiment that released more energy than was inputted by the lab’s equipment.

For AL_A’s plant, the central cylindrical fusion hall is surrounded by a radial arrangement of support systems, all of which are equidistant from the core. In our 20...

World's biggest nuclear fusion project completes civil engineering work on Tokamak Building

2019-11-13T15:29:00-05:00

A Vinci-led consortium [...] completed civil engineering works on the high-spec building that will house the world’s largest fusion machine, called a “tokamak”, which scientists hope will start replicating the sun’s energy by the middle of the next decade. [...] The 73-metre-high, 120-metre-wide structure required highly specific concretes. Teams developed about 10 formulations to shield staff and the environment from fusion-generated radiation.

Building a tokamak machine to exploit fusion energy similar to our sun is no simple engineering feat: the building will house reactions that happen at extremely high temperatures, around 150 million degrees Celsius, fusing hydrogen nuclei when they reach the plasma state, thus releasing enormous amounts of energy in the process.

ITER, the international organization tasked with operating and subsequently dismantling the experimental facility, hopes to maintain its ambitious First Plasma target in 2025.

"Some parts of the Tokamak Building also called for steel reinforcement density rarely used on projects on this scale (up to 10 times the density of an apartment building wall)," explains a statement released by French contracting giant VINCI.

"[...] access to the heart of the Tokamak Building required customized production of 46 heavy nuclear doors. Each 70-tonne door is manufactured in Germany, brought to the site, filled with concrete and assembled in the hea...

Carbon-free nuclear fusion power within reach, according to MIT

2018-03-09T13:55:00-05:00

The dream of nuclear fusion is on the brink of being realised, according to a major new US initiative that says it will put fusion power on the grid within 15 years. The project, a collaboration between scientists at MIT and a private company, will take a radically different approach to other efforts to transform fusion from an expensive science experiment into a viable commercial energy source.

Potentially an inexhaustible and carbon-free source of energy, the dream of making fusion power commercially viable appears to be getting a lot closer, according to a new announcement from researchers at MIT this morning.

"Fusion is the true energy source of the future, as it is completely sustainable, does not release emissions or long-term waste, and is potentially inexhaustible," said Claudio Descalzi, CEO of Italian energy company Eni which is currently collaborating with MIT on the project. "It is a goal that we are increasingly determined to reach quickly."

The research team is confident to have a first working reactor up and running within 15 years.
