MYRRHA consortium

The MYRRHA consortium is a European research and development partnership centered on the design, construction, and operation of a multi-purpose accelerator-driven system (ADS) designed for nuclear research, isotope production, and waste transmutation. The consortium links public research organizations, national laboratories, universities, and industrial partners from across Belgium, France, Germany, Spain, Italy, United Kingdom, Netherlands, Sweden, Switzerland, Poland, Czech Republic, Hungary, Romania, Slovakia, Portugal, Greece, Norway, Finland, Denmark, Austria, Israel, Japan, United States, Canada, South Korea, China, and Russia in coordinated programs that intersect with major European initiatives such as Euratom, Horizon 2020, and Horizon Europe.

Overview

The consortium aims to deliver a flexible, lead-bismuth-eutectic (LBE) cooled ADS integrating a high-power proton accelerator, a spallation target, and a subcritical reactor core to demonstrate technologies relevant to nuclear reactor safety, radioisotope production, and radioactive waste minimization. Partners include national research institutes like SCK•CEN and CEA, major universities such as Katholieke Universiteit Leuven, Université catholique de Louvain, Eindhoven University of Technology, and Politecnico di Milano, and industrial firms like Thales, Rolls-Royce, EDF, Siemens, and ANSALDO ENERGIA. The effort connects to test facilities and programs including ITER, JRC Petten, CEA Cadarache, TRIUMF, CERN, GANIL, J-PARC, and RIKEN.

History and Development

Concepts leading to the project trace to accelerator-driven system proposals by Carlo Rubbia and collaborative European studies in the 1990s, influenced by programs at Oak Ridge National Laboratory, Los Alamos National Laboratory, CEA, and SCK•CEN. Formal consortium organization expanded after strategic reports from European Commission directorates and policy recommendations from Council of the European Union and Committee for European Normalisation. Key milestones involved accelerator prototypes influenced by developments at CERN RF programs, superconducting linac research at DESY, and beam diagnostics from RAL, ESS, and PSI. Project phases interacted with regulatory frameworks overseen by Belgium's Federal Agency for Nuclear Control and international standards bodies like IAEA.

Consortium Structure and Members

The governance model is a multi-tiered partnership with a central project office at SCK•CEN in Mol, a technical board composed of representatives from participating laboratories, and work packages led by universities and industrial consortia such as CNRS, TU Delft, ETH Zurich, KTH Royal Institute of Technology, Università di Bologna, Gran Sasso Science Institute, Politehnica University of Bucharest, VTT Technical Research Centre of Finland, and INRNE. Membership spans national agencies like CSIRO, ANSTO, CEA, CEA LIST, PSI, NPL, ENEA, and regional actors including FWO, FNRS, and Walloon Region research programs. Advisory input has come from committees including experts previously affiliated with US DOE, UKRI, DFG, SNRC, and JSPS.

Technical Objectives and Research Programs

Primary technical goals encompass demonstration of high-reliability continuous-wave proton accelerators, LBE thermal-hydraulics, spallation target engineering, fuel loop testing for minor actinide transmutation, and production of medical isotopes such as those used in PET and SPECT by organizations like IAEA partner labs. R&D work packages cross-link accelerator physics from CEA-Saclay and INFN, materials science with inputs from CERN Materials Group and CEA-IRSN programs, computational modeling using codes developed at RSICC and CEA-LEPh, and safety case development in alignment with standards from ASN and USNRC. Collaborations extend to neutron research programs at ILL, ESS, SNS, and J-PARC.

Facilities and Infrastructure

Central infrastructure centers on the SCK•CEN site in Mol with planned buildings for accelerator tunnels, target stations, hot cells, and materials examination laboratories. Experimental facilities tie into European neutron sources and hot laboratories such as JRC-Geel, JRC-Petten, CEA-LETI, TU Delft Reactor Institute, NRC Canada Chalk River Laboratories, and NRI Řež. Accelerator component fabrication leverages industrial sites of Thales Alenia Space, Alstom, and Schneider Electric as well as cryogenic expertise from Air Liquide and Linde. Analytical support involves synchrotron and microscopy centers like ESRF, EMBL, MAX IV, and Diamond Light Source.

Funding and Governance

Funding derives from a mix of national contributions, Euratom framework grants, and in-kind industrial investment with oversight by a steering committee representing major funders including Belgian Federal Government, Walloon Region, Flemish Government, European Commission, European Investment Bank, and national research councils such as FWO, BELSPO, ANR, DFG, EPSRC, NWO, SNSF, and Horizon Europe program committees. Governance practices incorporate contractual frameworks modeled on consortium agreements used by CERN and procurement procedures compatible with European Investment Bank policy and national procurement laws.

International Collaborations and Partnerships

The consortium maintains formal and informal partnerships with international laboratories and programs such as IAEA, OECD Nuclear Energy Agency, ITER Organization, EPRI, US DOE National Laboratories, JAEA, KAERI, CNL, and standards bodies like ISO technical committees. Scientific exchanges and student training involve universities including University of Cambridge, Imperial College London, Sorbonne University, University of Oxford, ETH Zurich, University of Tokyo, and Tsinghua University.

Challenges and Future Prospects

Challenges include technical risks in high-power accelerator reliability, materials compatibility with LBE, regulatory licensing under Belgian and international frameworks, long-term funding continuity, and supply-chain coordination across industrial partners such as Areva (now Framatome), Mitsubishi Heavy Industries, and Doosan Heavy Industries. Prospects hinge on demonstrating transmutation of minor actinides, secure production chains for medical isotopes, and potential industrial deployment pathways influenced by energy policy debates involving European Green Deal and strategic agendas by European Commission and national ministries. Successful demonstration could influence reactor concepts studied by Generation IV International Forum, impact waste management strategies promoted by NEA, and shape collaborations with research reactors and particle accelerator infrastructures worldwide.
