Nuclear fission energy is a proven technology that provides today
31% of electricity in the EU-27, with reactors in 15 countries. It
is the largest source of low carbon electricity, saving nearly 900
mT of CO2 emissions a year. It contributes to Europe’s security of
supply by limiting the dependence on fossil fuel imports. Building
up on its present leading position, Europe has to invest in R&D
to overcome technological breakthroughs that would guarantee
Europe’s future low Carbon energy mix and energy security of supply.<br>
<br>
In this talk, we will report on this vision and on the innovative
nuclear systems as well as the status of the MYRRHA project and
their perspective and how this can lead to sustainable nuclear
energy use.<br>

Accelerator Driven Systems (ADS) are promising tools for the
efficient transmutation of nuclear waste products in dedicated
industrial installations, called transmuters. The MYRRHA project at
Mol, Belgium, placed itself on the path towards these applications
with a multipurpose and versatile system based on a liquid PbBi
(LBE) cooled fast reactor (80 MWth) that may be operated in both
critical and subcritical modes. In the latter case, the core is fed
by spallation neutrons obtained from a 600 MeV proton beam hitting
the LBE coolant/target. The accelerator providing this beam is a
high intensity CW superconducting linac delivering a 4 mA beam and
which will be laid out for the highest achievable reliability. The
combination of parallel redundant and of fault tolerance
implementing schemes should allow obtaining a beam MTBF value in
excess of 250 hours that is required for optimal integrity and
successful operation of the ADS. MYRRHA is expected to be
operational in 2023. The forthcoming 3-year period is fully
dedicated to R&D activities, and in the field of the accelerator
they are strongly focused on the reliability aspects and on the
proper shaping of the beam trip spectrum. The R&D effort takes
advantage of the highly modular structure of the linac which allows
for efficient prototyping.<br>
