TRISO fuel-led nuclear innovation

Fueling Safer Nuclear Power

Across Reactor Generations

TRISO — tri-structural isotropic fuel — is an accident-tolerant fuel architecture designed to retain fission products under extreme operating and off-normal conditions. Its multi-layer particle design offers potential relevance across both advanced reactors and existing reactor platforms, where fuel resilience, safety margins, lifecycle cost, and decarbonisation are increasingly important.

KNE focuses on what makes TRISO deployable at scale: repeatable manufacture, rigorous QA/QC, certification-aligned evidence, reliable qualification pathways, and dependable logistics — supporting safer, zero-carbon electricity and industrial heat with long-term cost efficiency.

Why TRISO matters

Fuel-form containment

Layered coatings are engineered to retain fission products within the particle under demanding conditions.

High-temperature resilience

TRISO programs target elevated temperatures; qualification evidence becomes the credibility anchor.

Certification leverage

Certified fuel materially de-risks system certification and accelerates credible project development.

Commercial reality

In many AMR concepts, TRISO fuel can be a majority share of lifecycle cost; yield and repeatability matter.

Balanced view: engineering and commercialization

KNE starts with fuel fundamentals, then moves through fabrication readiness, qualification evidence, supply-chain assurance, and market sequencing. The commercial pathway is U.S. first, with Europe as a scale market

How TRISO is made (high level)

TRISO fuel manufacturing is typically described in three primary stages: kernel manufacturing, coated particle manufacturing, and fuel-form manufacturing (compacts or graphite pebbles), with vigorous QA/QC and recycling of rejects where appropriate.

1
Kernel manufacturing
Fuel kernels formed to specification (UO₂/UCO/ThO₂, depending on program design).
2
Coated particle manufacturing
Buffer + IPyC + SiC + OPyC layers deposited via FCVD; coated particles are sub‑millimeter.
3
Fuel-form manufacturing
Particles integrated into compacts or graphite spheres; dimensions and integrity verified.
