They cut through four fences, set off sensors and alarms, hammered on the outside of the storage building, and defaced it with paint and human blood. They remained on the site for over an hour before a guard finally arrested them.

# Fresh Thinking on Highly Enriched Uranium Research Reactor Conversions

By William Tobey

Last week, a National Academies of Sciences, Engineering, and Medicine panel affirmed the goal of eliminating highly enriched uranium (HEU) from civilian use, while recommending step-wise conversion of high performance research reactors using weapon-grade uranium fuel and that the White House coordinate a 50-year national roadmap for neutron-based research. (Full disclosure:  I sat on that committee, and oversaw the NNSA reactor conversion program from 2006-9; this post, however, represents my views, not necessarily those of the committee or NNSA.)
