Tokamak Energy news

A slide from APS-DPP 2024:

4.25 meters radius! That is pretty big!
For reference that is more than 2/3 the size of ITER!
And that is for 80 MWe power out. So it is marginally smaller than ITER and also uses HTSCs.
ARC is a conventional Tomakak and 270 MWe with a major radius of only 3.3 m...
I thought STs were supposed to be more compact, especially with HTSCs.
Otherwise, what is the point?

B field strength also seems low compared to other projects. Is this due to the size?

Tokamak Eenergy has issued a press release where these details of their pilot plant are repeated. The size is indeed big and the magnetic field lower than expected for HTS. Also the electrical power output is low compared to what one would expect, so the plan seems a bit odd without the motivations behind it?

Tokamak Energy is designing a pilot plant capable of generating 800 megawatts (MW) of fusion power and 85MW of net electricity – enough to power and heat more than 70,000 American homes.

The plant will include a complete set of new generation high temperature superconducting (HTS) magnets to confine and control the deuterium and tritium hydrogen fuel in a plasma many times hotter than the centre of the sun. Initial designs are for the tokamak to have an aspect ratio of 2.0, plasma major radius of 4.25 metres and a magnetic field of 4.25 Tesla, as well as a liquid lithium tritium breeding blanket.

Yo, wonder whats up with that. Oddly enough, their major radius is exactly the same as the latest version of ARC by CFS.

The investment round will support the rapid growth of TE Magnetics to address demand from the fusion energy market and open new fields of performance in other industries including science, mobility, renewable energy and security.

It will also advance the company’s leading fusion pilot plant design programme, as well as develop, test and validate new fusion technologies using its record-breaking high field spherical tokamak ST40 for ground-breaking experiments near Oxford.
