Myrrha accelerator driven system programme: recent progress and perspectives

The purpose of the MYRRHA programme is to demonstrate the ADS concept at pre industrial scale, to prove the transmutation efficiency in ADS and to serve as a flexible and multipurpose irradiation facility. The MYRRHA sub critical core fueled with highly enriched MOX fuel and cooled with LBE will be operated by a high power superconducting linear accelerator delivering a proton beam of 600 MeV, 4 mA to an LBE spallation target. In September 2018, the Belgian government has approved the construction of the MYRRHA facility and its operation until 2038. In this paper, we describe the present status of the MYRRHA programme and the perspectives for implementation through a first infrastructure in 2026 to the full MYRRHA operation in 2036.
