Division Spotlight
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

Sven Bader
Session Organizer:
Fossil uranium is often separated into at least two categories, such as low-enriched uranium (LEU, with <20% U-235), and high-enriched uranium (HEU, with >20% U-235). Occasionally, LEU is further split into categories such as LEU+ (5-10% U-235) and high-assay LEU (10-20% U-235). However, plutonium never appears to be sub-divided into sub-categories, regardless of whether it is, for example, reactor-grade or weapons-grade plutonium. This panel will discuss the pros and cons of potentially dividing plutonium into sub-categories of importance (similar to uranium) and the potential to develop an ANS position statement support this position.
