We used HTR-type compact fuel with ZrO 2 TRISO particles to test two separation methods: low (H 2 SO 4 + H 2 O 2) and high (H 2 SO 4 + HNO 3) temperature acid treatments. The 34% fuel cost includes all front end and waste … Radiation Effects in Materials for Fission Energy Systems Section 6. The TRISO-X Particle is its own vessel, designed by our scientists to be the best fuel on Earth and the Department of Energy agrees. USNC describes FCM as a next-generation uranium oxycarbide tristructural isotropic (TRISO) particle fuel design, replacing the 50-year-old graphite matrix of traditional TRISO fuel with silicon carbide (SiC). It says the result is a safer nuclear fuel … The companies signed a services contract to proceed with the preliminary design of a facility to fabricate advanced nuclear fuel for the X-energy Xe-100 high temperature gas-cooled reactor, which is designed to use HALEU TRISO fuel. Combined with recent bipartisan legislation, this latest development in fuel demonstrates a growing momentum for new nuclear reactors. This is expected to produce TRISO fuel of "significantly higher quality and at costs that are substantially lower than other potential manufacturers." TRISO-X Fuel IS the containment vessel. Advanced Fuel Concepts, Research Reactor Fuels, and Space Applications Section 5. Spent Fuel Processing and Waste Disposal Section 9. Past irradiation performance 7.2. State of the art in TRISO-coated particle fuel irradiations 7.2.1. Reactor considerations 7.2.2. Table 2.1 LWR TRU Waste and TRISO Inventory from 1000kg CSNF. X-energy has a TRISO pilot fuel fabrication facility at ORNL. This fuel is being built by a company called X-energy 20 for their high temperature gas cooled reactor. 6.1. For example, tristructural isotropic (TRISO) fuel has several layers of carbon and carbide that serve as the primary containment for radioactive material. Key TRISO-X Fabrication Processes Note: The initial license application will cover pebble fuel element fabrication, any additional fuel forms would be No more expensive, gigantic concrete and steel structures to build, maintain and get rid of. Table 2.2 TRISO Fuel, Compact, Element, and Waste Package Data. In-core graphitic materials 6.3. Corrosion, Compatibility, and Environmental Effects Section 8. The TRISO-X fuel fabrication facility will produce fuel elements ranging from natural uranium to 19.75% enriched. In addition, preparation of acid-GICs from the separated graphite may constitute a way to recycle this waste. The Defense Department specified TRISO fuel in its request for solutions because the fuel is so robust. The TRISO-X facility will be Category II as defined in 10 CFR Part 70. And, under DOE’s Advanced Gas Reactor (AGR) Fuel Development Program, BWXT has manufactured and certified TRISO coated kernels and fuel compacts in production-scale quantities. Hexagonal block fuel elements for the prismatic HTGR design 6.2. In November 2019 X-energy and GNF agreed to set up commercial HALEU TRISO production at GNF's Wilmington plant in North Carolina. TRISO-COATED PARTICLE FUEL IRRADIATIONS 7.1. TRISO particles have a fuel kernel made up of a mixture of uranium and oxygen or uranium oxycarbide that is then coated with three layers: (1) an inside layer of high-strength pyrolytic carbon, (2) silicon carbide, and (3) an outer layer of pyrolytic carbon. Table 2.5 Inventory of CSNF and DBSF. INL scientists are researching nuclear fuels that are more tolerant to accident conditions, utilize energy resources more efficiently or leave fewer long-lived waste isotopes behind. Section 4. Tri-structural isotropic (TRISO) fuel is an innovation in physical composition that makes the fuel immune to meltdown. Table 3.1 Graphite, SiC, and PyC Degradation Rates in Aqueous Solution.
