Pioneering TRISO Fuel for Advanced Reactors
TRISO (tri‑structural isotropic) is a micro‑particle fuel architecture: a fuel kernel (commonly UO₂, sometimes UC/UCO) protected by four engineered layers deposited via fluidized chemical vapor deposition (FCVD). KNE focuses on what makes TRISO deployable at scale—repeatable manufacture, rigorous QA/QC, certification-aligned evidence, and dependable logistics. TRISO‑based reactor concepts can deliver zero‑carbon electricity and industrial heat at the point of generation, supporting environmental objectives and decarbonisation.
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.
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.
Fuel kernels formed to specification (UO₂/UCO/ThO₂, depending on program design).
Buffer + IPyC + SiC + OPyC layers deposited via FCVD; coated particles are sub‑millimeter.
Particles integrated into compacts or graphite spheres; dimensions and integrity verified.
