GNF test rods complete first fuel cycle at Hatch nuclear station

The world’s first accident-tolerant fuel rods using technology by Global Nuclear Fuel (GNF) have successfully completed a first two-year test fuel cycle at Unit 1 of the Hatch nuclear power station in Georgia, operator Southern Nuclear said.

According to Southern Nuclear, during a planned maintenance and refuelling outage, operators transferred samples of the lead test rods to the onsite spent fuel pool and have completed an initial inspection of the fuel to compare it to standard zirconium rods.

GNF’s accident tolerant fuel assemblies are of two types: one uses an iron-chromium-aluminium fuel cladding material known as IronClad and the other – a coated zirconium fuel cladding known as ARMOR.
