The engineering and the physics, in the open.

A 1005-page technical library covering the physics, validation, engineering, materials, methodology and open-science record behind Kronos Fusion Energy's breeder–burner architecture. Every figure is a computed design target traceable to our open Zenodo deposits.

Physics & Fusion Science 31 pages

The physics behind the Kronos breeder–burner architecture — confinement, stability, transport, heating, and the fuel cycles — grounded in decades of experimental fusion science.

Validation & Reproducibility 6 pages

How Kronos checks its own physics: a graded validation suite, a byte-exact reproduction protocol, and an open deposit anyone can re-run.

Process & Methodology 17 pages

How Kronos actually works: the design method, the simulation stack, the freeze discipline, the gate reviews, and the honesty framework that runs through all of it.

Innovations & Distinctives 10 pages

What Kronos does differently — the architectural, commercial and cultural choices that set the breeder–burner approach apart from the rest of the field.

The Technology Stack 10 pages

The enabling technologies behind Kronos — high-field magnets, direct conversion, the plasma and fuel technology, and the digital, AI and simulation stack that designs it.

Engineering & Subsystems 22 pages

The subsystems that turn a plasma physics point into a plant — magnets, vessel, blanket, divertor, heating, power conversion, cryogenics and controls.

Components & Hardware 37 pages

The machine, part by part — every major component of the breeder and burner, what it does, what it is made of, and how mature it is. Representative to the frozen design.

Operations & Commissioning 10 pages

How a built machine is commissioned, operated, maintained and refuelled — from cold systems through first plasma to steady operation.

Materials & Magnets 18 pages

The materials that make a compact, high-field fusion machine possible — superconductors, structure, plasma-facing components — and the honest limits on each.

Diagnostics & Measurement 8 pages

How you measure a plasma hotter than the Sun's core without touching it — the instruments that turn a fusion machine into a scientific one.

Products & Applications 12 pages

One physics core, several products: the breeder's isotopes and neutrons, and the burner as MetroVolt and AEGIS across grid, data-centre, defence and space applications.

Applications & Markets 10 pages

Where Kronos's output is used: firm grid and data-centre power, resilient defence installations, tritium and isotopes, helium-3 for quantum and medicine, and industrial heat.

Open Science & Publications 7 pages

The open record behind Kronos — five Zenodo deposits, the peer-review track, how to cite the work, and the granted and pending patents.

Glossary of Fusion & Plasma Terms 699 pages

Plain-language, technically precise definitions of the physics, engineering and plasma terms that appear across the Kronos design record.

Questions & Honest Answers 43 pages

Direct answers to the questions serious reviewers ask — about the physics, the claims, the risks, and what is and is not yet proven.

Team & Heritage 3 pages

The experience behind Kronos — decades of work across the world's fusion and large-science programmes, described at the level the public record already reflects.

Safety & Environment 13 pages

Why fusion is inherently safe, what its waste and footprint really are, and how Kronos treats the honest environmental questions rather than hand-waving them.

Codes & Standards 12 pages

The engineering codes and standards a fusion plant is designed, built and licensed against — from pressure vessels and functional safety to materials and quality.

Comparisons & Context 7 pages

How fusion compares with other energy sources, and how the Kronos approach compares with other fusion paths — argued honestly, on the merits.

Competitive Landscape 11 pages

How the fusion field is organised — by confinement approach, by fuel, and by business model — and where the Kronos breeder–burner architecture sits. Public-sourced and factual.

Reference Devices 12 pages

The public and historical machines whose results underpin the fusion database Kronos designs against — the tokamaks, mirrors and facilities that established the science.

History & Context 7 pages

How fusion research arrived at the compact, high-field, open-science moment — and where the Kronos breeder–burner architecture sits in that story.
