Description
A neutron spallation source for an Accelerator Driven System, commonly known as an ADS Target, must be able to function reliably and safely for the ADS concept to take hold as a viable option in the commercial sector. Targets operating at Megawatt level already exist but have, on the whole, been optimised with physics in mind. The "ideal" ADS target should, in addition to physics considerations, integrate inherent nuclear safety and reliability requirements borne of decades of experience in the nuclear power engineering sector.
Starting from basic nuclear safety requirements, a review of different options for ADS targetry provides an insight into the possible options for designing an ADS target. Existing designs from projects such as Megapie and Eurisol serves to illustrate the relative merits and weaknesses in specific target designs. Integrating such considerations early enough in the design stage would be of benefit to licensing an ADS operating at a power level compatible with its industrial potential, be it for waste transmutation or energy production.
