MYRRHA: A Flexible and Fast-Spectrum Irradiation Facility

MYRRHA (Multipurpose hYbrid Research Reactor for High-tech Applications) is a multipurpose research facility currently being developed at SCK•CEN. MYRRHA is based on the ADS (accelerator-driven system) concept, where a proton accelerator, a spallation target, and a subcritical reactor are coupled. MYRRHA will be able to work in both critical and subcritical modes, enabling the facility to target a broad range of R&D applications. In this paper, the most recent developments of the design of the MYRRHA facility are presented, as well as the irradiation performance of MYRRHA.
