The main objectives of the JHOP2040 proposal:
- Strengthen and widen the JHR research network by bringing together relevant stakeholders and interest groups to identify and review their current and future needs in terms of research and irradiation experiments as well as PIE studies. It is especially important that this roadmap enhances collaboration with organisations, within and outside of the current JHR consortium, that can utilise JHR via Euratom access rights
- Make full use of the planned JHR capacity by promoting and enhancing the collaboration between potential users while taking into consideration the evolution of nuclear materials, fuels and measurement technologies and also the future needs of education, training and widening access in the nuclear industry. This will include research, demonstration and innovation concerning the existing Gen II and III as well Gen IV fission reactors and those for fusion needs. JHOP2040 intends to promote through the listed activities a better understanding, a closer dialogue and active co-operation between research, industry, associations and safety authorities to support future use of safe, efficient and sustainable nuclear energy.
- Create the roadmap for the first four years of JHR operation (“Roadmap-4”) by employing the research infrastructure available and taking into account the commissioning phase experience on operation and objectives #1 and #2. This first period of operation will differ from the later ones as the available experimental fleet will be limited and the long-term research programmes, including the proprietary programmes, will be being built at the same time, so flexibility and lean cooperation will be needed.
- Create the roadmap for 15 years from the start of first irradiation (“Roadmap-15”), i.e. covering the following 11 years after Roadmap-4. Future fuel and material research will be reflected with the NFRP-08 CSA ORIENT-NM and this will be considered, as will the production of medical isotopes and its effects on e.g. reactor availability and cost breakdown. The roadmap will include the research programme structure and governance including resource and cost breakdown, as well as the model for the financing of the programmes.
