GE ATF Program

NRC Commissioners Briefing January 24, 2023

Rich Augi LWR Fuel Product Director GE ATF Program Overview

Technologies Being Developed Program Development Goals Safety Durability Temperature Oxidation Fretting Resistance Stability of fuel rods at Provide a step-change Increased resistance of fuel higher temperatures in oxidation resistance cladding to debris fretting Economics

Fuel Cycle Economics Enabling sustained economic performance through minimizing cost and improving efficiency Core Team

ARMOR IronClad Higher Other Technology

• Abrasion Resistant More *Iron Chrome Aluminum Enrichment/Higher

• Channel coatings, ceramic Oxidation Resistant (FeCrAl) based alloy Burnup matrix composite

• Coated fuel rods *Alternative to zircalloy *Fuel Cycle Economics, lower

• Alternate ceramics for fuel

• Resists high temperature cladding batch fractions, less back

• Methodology oxidation *Fret Resistant end/disposal waste improvements

• Mitigates debris fretting *Substantial hydrogen *Longer cycles between

• Protects against normal reduction refueling outages corrosion *Offsets potential added

• Thermal limits margin costs of ATF safety benefit technologies 2018: Hatch Lead Test Assemblies (ARMOR, IronClad) 2019: Clinton Lead Test Assemblies (ARMOR, IronClad)
