XT-ADS Windowless spallation target thermohydraulic design & experimental setup

Study of steady-state heat transfer with various large beam intensities in ADS windowless spallation target

“…During EUROTRANS the design of the windowless target has been evolved substantially so that the latest design (V0.10) conforms to specifications [1]. The overall dimension is F196.96 mm  725.1 mm and the size of the vacuum tube is F91.7 mm  305.13 mm.…”

“…Accelerator driven system (ADS) [1] consists of proton beam accelerator, spallation target and reactor which is being developed for management and disposal of high level nuclear wastes. At the center of the subcritical core, a spallation target provides the primary neutron source that is amplified to obtain the neutron flux required for fission and transmutation.…”

“…The thermal hydraulics design of the target is a challenging task, as the space available is very limited and the maximum heat load is about 300 W/cm 3 and the total heat deposit reaches 2.1 MW [1]. Previous work focuses on the heat transfer in the spallation target with a window.…”

Experimental and numerical study on the flow pattern of the ADS windowless spallation target with a second free surface downstream using model fluid water

“…However, it is still in the stage of concept and design development. The Integrated Project EUROpean Research Programme for the TRANSmutation of High Level Nuclear Waste in Accelerator Driven System (EUROTRANS) have been carried out aiming to demonstrate the feasibility of transmutation in an advanced 50-100 MWth experimental accelerator driven facility XT-ADS (Class et al, 2011). The spallation target is one of its key components.…”

“…Therefore, the spallation target works in a harsh irradiation environment with large amount of heat deposit and heavy metal corrosion. Its design is one of the key issues in the development of the ADS and is studied actively recently (Class et al, 2011). In early days, cooled solid targets were designed.…”
