How do you make TRIGA fuel?

TRIGA (Training, Research, Isotopes, General Atomics) fuel is typically made by combining uranium powder with a zirconium hydride matrix. The uranium is usually enriched to a low level (around 20%) to ensure safety and suitability for research reactors. The mixture is then pressed into cylindrical fuel elements and subjected to sintering, which involves heating to create a solid, dense structure. Finally, the fuel elements are often coated or cladded to protect against corrosion and ensure structural integrity during operation.
