Description
Accelerator-driven subcritical systems (ADS) represent an advantageous option for the transmutation, volume reduction, and safe disposal of nuclear waste. Neutron spallation sources for Accelerator Driven Systems, commonly known as ADS Targets, must at the same time feature high performances from a neutronics point of view and function reliably and safely, especially in the current scenario where the ADS concept takes hold as a viable option in the commercial sector.
Most of the ADS facilities currently being designed or constructed are meant to be operated in the next decade. All the concerned projects highlight the challenges associated with the usage of spallation targets as interfaces between multi-megawatt charged particle beams and subcritical cores operating at significant thermal power.
A review of different options for ADS targetry is presented in this talk, with particular emphasis on requirements, perspectives, and needed R&D programs.
