Beam physics design of a 30-MW beam transport to the target for an accelerator-driven subcritical system

Bruce Yee-Rendón, Shin-ichiro Meigo, Yasuhiro Kondo, Jun Tamura et autres

Abstract The Japan Atomic Energy Agency's accelerator-driven subcritical system (JAEA-ADS) proposes the reduction of nuclear waste through the transmutation of minor actinides. The JAEA-ADS drives a 30-MW proton beam to a spallation target to produce neutrons for a subcritical 800-MWth reactor. The …
