The IABAT project is a preliminary assessment of the potential of accelerator-driven systems (ADS) for transmutation of nuclear waste and, additionally, for nuclear energy production with minimum waste generation.

The tasks of the project cover ADS and fuel cycle studies (including aspects of reducing risks from waste repositories and proliferation aspects of ADS), nuclear and material data development and assessment of accelerator technology.

Four ADS have been studied in detail: liquid lead and lead/bismuth cooled fast systems with solid fuel, liquid lead thermal system with dispersed fuel, and fast and thermal molten salt systems. Neutronic studies assessed transmutation potential of these systems for different fuel cycles and operation strategies. Some measures to ensure compliance of ADS systems with non-proliferation principles were proposed.

Efforts were put into the IABAT project to assess the simulation tools for spallation targets and to propose solutions that may mitigate some of the problems arising on merging accelerator and nuclear technologies.

In assessment of accelerator technology, costing models have been developed based on existing technology for cyclotron and linear accelerators. Moreover, reliability and availability studies for a linear accelerator have been performed based on the data from the LANSCE accelerator. Finally, impact on the risk from high-level waste repositories from radio-toxicity reduction using ADS has been investigated showing no unquestionable benefits of ADS for repository radio-toxicity reduction.
