Fuel Fabrication, Qualification and High Temperature Materials Fuel Fabrication and Production o X-energys TRISO-X commercial-scale fabrication capability is producing high-quality coated-particle fuel today.
Fuel Transportation o Versa-Pak 55 containers ready for finished-product transport.
Fuel Qualification & Performance o The Xe-100 benefits from the DOE Advanced Gas Reactor Fuel R&D program activities like the 2019 EPRI-sponsored TRISO fuel performance topical report & 2020 NRC safety evaluation.
High Temperature Materials o Final endorsement of ASME BPVC Section III, Division 5 standard for High Temperature Reactors will provide confidence in associated design and analysis results.
99.999% of Fission products Retained These 1mm particles retain 99.999% of the fission products
