Urenco LEU+ Nuclear Fuel Trial in UK
Sector: Nuclear • Location: United Kingdom
Source: Geomechanics.io
Urenco has completed a UK trial to produce Europe's first batch of LEU+ nuclear fuel, enriched above conventional low-enriched uranium but below the 20% U-235 threshold, for use in existing gigawatt-scale reactors and planned small modular reactors. The higher assay fuel is designed to extend fuel cycle length compared with standard LEU, potentially reducing refuelling outages and spent fuel volum

Description
Description | Urenco has completed a UK trial to produce Europe's first batch of LEU+ nuclear fuel, enriched above conventional low-enriched uranium but below the 20% U-235 threshold, for use in existing gigawatt-scale reactors and planned small modular reactors. The higher assay fuel is designed to extend fuel cycle length compared with standard LEU, potentially reducing refuelling outages and spent fuel volumes per megawatt-hour. This development impacts core design margins, outage scheduling, and long-term storage and transport requirements for higher-burnup fuel. |
