The pebble bed reactor is one of the most promising concepts for (V)HTR. Nevertheless recent re-evaluation of AVR and THTR results emphasizes once more that claimed advantages strongly depend on the properties of the fuel elements and their behavior

One of the main technical concerns of Megawatt-class spallation neutron sources is the removal of the heat deposited in the target station. A way to overcome it is to use targets consisting of flowing liquid metals, but the already tested materials

At sites with powerful particle accelerators, the problem of groundwater activation by direct neutron radiation arises. Licensing of particle accelerators requires evidence that groundwater activation is within the legal limits and thus will not enda

Large spallation sources are intended to be constructed in Europe (EURISOL nuclear physics facility and European Spallation Source). These facilities accumulate more than 20 tonnes of irradiated mercury in the target, which has to be treated as highl

The AVR pebble bed reactor (46 MWth) was operated 1967 – 1988 at coolant outlet temperatures up to 990°C, which are suitable for process heat applications. Also because of a lack of other experience the AVR operation is a basis for future HTRs. Th
