Void Reactivity Worth in Uranium/Lead Systems: A US-Japan Collaboration

摘要

Researchers at the Japanese Atomic Energy Agency (JAEA) Fast Critical Assembly Facility (FCA) in Tokai, Japan and at the Los Alamos National Laboratory (LANL) are collaborating on a series of experiments at the National Criticality Experiments Research Center (NCERC). One area of mutual interest is lead cross section and void reactivity worth This paper will focus on two series of experiments-a highly enriched uranium (HEU)/lead core and a low enriched uranium ("LEU")/lead core. The experiments were designed jointly with LANL researchers performing the experiments.
