Lightbridge announces first U-Zr fuel rod samples extruded at INL
Lightbridge Corporation announced today that it has reached “a critical milestone” in the development of its extruded solid fuel technology. Coupon samples using an alloy of zirconium and depleted uranium—not the high-assay low-enriched uranium (HALEU) that Lightbridge plans to use to manufacture its fuel for the commercial market—were extruded at Idaho National Laboratory’s Materials and Fuels Complex.

The laser challenges and state of the art in high-energy, solid-state petawatt lasers for fast ignition (FI) research are reviewed. A number of new laser systems are currently under construction or being planned that will facilitate proof-of-principle FI experiments. Recent technological advances in each of the major ultrafast laser subsystems are reported, including chirped-pulse generation and broadband amplification in the front end, high-energy amplification, and pulse compression with adaptive wavefront correction. Unique challenges related to operating high-energy chirped-pulse-amplification laser systems for FI, such as protection from target back reflections, are also addressed.
