MYRRHA: research reactor in development
MYRRHA stands for Multi-purpose hYbrid Research Reactor for High-tech Applications. It is a multifunctional research facility for innovative applications. MYRRHA is the world’s first prototype of a subcritical lead-bismuth cooled reactor driven by a particle accelerator.
The particle accelerator is used as an external neutron source to create the chain reaction. This external neutron source is vital to maintain nuclear fission. It is a particularly safe and highly controllable nuclear technology: when the particle accelerator is switched off, the nuclear reaction stops automatically.
Ready in 2025
Less radioactive waste
The development of MYRRHA started in 1998. We plan to have this multipurpose irradiation facility fully operational by 2025. Eventually MYRRHA will replace our BR2
reactor for materials research, the production of radioisotopes
(important in the battle against cancer
) and silicon doping
(for production of semi-conductors present in power electronic systems). In addition, MYRRHA is intended to play an important role in the training of future generations of nuclear experts.
MYRRHA also allows us to study how we can convert long-lived into short-lived waste radioactive waste. This process, known as transmutation
, results in waste of reduced radiotoxicity and consequently risk. In addition, we will be able to bring down the disposal time needed for this waste from several hundreds of thousands of years to less than 1000 years.
Thanks to its unique properties, the MYRRHA particle accelerator is particularly interesting for fundamental scientific research. This is why we develop in parallel with MYRRHA an infrastructure that will make a whole new category of experiments
