The ESS target station hot cell facility and associated logistics for ICANS 21

The European Spallation Source (ESS), Lund, Sweden will be a 5 MW long pulsed neutron research facility with planned commissioning in 2019. Connected to the target station building, a hot cell facility will deal with the large, heavy and complex radioactive components as they reach their lifetime limit after service in the neutron research facility. The hot cell will be unique in its design for this specific reason. A special precondition for ESS, being a green field facility, is that there is neither a heritage nor any logistical constraints, which is often the case for existing facilities. The ESS will be operational for around 40 years once commissioned and the hot cell facility will be operative during the complete operational phase of ESS as well as being an important facility during the decommissioning phase of the ESS. This requires the design to have a very high degree of flexibility in order to adapt to changes of target station component designs as well as changes of the functional requirements for the hot cells themselves.
