Global Nuclear Fuel Introduces Next Generation Fuel Product for Boiling Water Reactors

Global Nuclear Fuel announced the introduction of GNF4, a next generation nuclear fuel product built on a 60-year legacy of boiling water reactor (BWR) fuel design innovation and performance.

The GNF4 product builds upon the operating history of GNF2 and GNF3 and features two advanced components that are licensed by the U.S. Nuclear Regulatory Commission: Ziron cladding and aluminosilicate doped uranium dioxide pellets.

Ziron cladding was developed to better resist corrosion, ensuring that fuel remains safe and reliable and is an enhancement to the Zircaloy 2 cladding that has been utilized in more than 175,000 GNF fuel assemblies worldwide. Aluminosilicate doped uranium dioxide pellets add an extra layer of reliability.

The first lead use assemblies of GNF4 are contracted for deployment in 2026 and full reload quantities are expected to be available in 2030.
