- •
A detail 3-D neutronic model of 10 MW ADS coupled 250 MeV proton accelerator was built.
- •
Both beam losses and leakage of particles through beam duct were considerated.
- •
The main contributors for upper radiation were beam duct leakage and secondary radiation induced by beam losses.
- •
The impact of beam losses on total dose was greater than that on total neutrons flux.
