Safety of operating nuclear power plants and research reactors

investigación innovación I+D+i desarrollo tecnológico europeo. HORIZON Research and Innovation Actions Expected Outcome: The project’s results are expected to contribute to some of the following expected outcomes. Continuing safety assessment and long-term operation compliance that address technical challenges, regulatory expectations and economic competitiveness goals. Licence-holders and regulators will ensure the successful implementation of the requirements of the Nuclear Safety Directive [1] , Basic Safety Standards Directive [2] , Radioactive Waste Management Directive [3] and topical peer reviews [4] for current and planned nuclear power plants and research reactors. Safety assessment of ageing management programmes and optimisation of safety solutions; as well as the development and validation of advanced tools for ageing management and evaluation of reactors’ safety margins. The aim is to prevent and mitigate risks (including those associated with severe accidents) by using innovative cross-cutting technologies (applicable to multiple reactor technologies), digital upgrades, digital twins, AI/ML-assisted defect detection, advanced multi-physics (including fluid structure interaction) and/or multiscale modelling and simulation, as well as PSA updates for extended operations.
