Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

For the purpose of the recovery of a hydrogen isotope exhausted from a fusion device and its application to a tritium monitor, hydrogen extraction properties using SrZr0.9Yb0.1O3- and CaZr0.9In0.1O3- and the effect of the electrode attachment method on the hydrogen extraction were evaluated under various atmospheres and temperatures. As a result, hydrogen could be extracted from mixed gases containing hydrogen, water vapor and methane. Furthermore, water vapor electrolysis for the tritium monitor was also evaluated under a wet atmosphere containing oxygen. From these results, it was revealed that a plated platinum electrode was suitable for mixed gases containing hydrogen, water vapor and methane, and that a porous pasted platinum electrode was suitable for water vapor electrolysis. From the findings obtained from the study of the hydrogen extraction properties, we described an optimum specification of the platinum electrode for a tritium recovery system and the number of proton-conducting ceramics for a tritium monitor.
