Transmutation of nuclear waste in accelerator-driven systems: Fast spectrum

摘要: Abstract The TRIGA accelerator-driven experiment is a milestone in the roadmap towards demonstration of transmutation nuclear waste systems (ADSs). It designed such way as to couple different components an ADS realistic environment by using existing critical reactor adapted experiment’s objectives, at significant power levels. This paper summarises neutronic characterisation system, essential step design and licensing process. feasibility demonstrated, establishing sub-criticality levels operation fuel rod configurations. analyses neutron distribution space, energy time detail behaviour real-power thermal identify extent limitations for experimental programme. Studies investigating potential system transmute transuranics long-lived fission fragments demonstrate need move fast order efficiently these major waste.
