METHODS AND TOOLS INNOVATIONS FOR SEISMIC RISK ASSESSMENT

Project description

Assessing the seismic safety of nuclear power plants

Nuclear power plants (NPPs) need to be able to withstand the effects of an earthquake. The EU-funded METIS project therefore aims to develop rigorous and efficient methodologies and tools to determine the seismic safety of NPPs. It will support simulation results with experimental data and experience feedback within the framework of Bayesian approaches and machine learning. By these means, the project will improve the predictability of best estimate and beyond-design seismic analysis. Together with the propagation of epistemic and aleatory uncertainties, this will make analyses more reliable and increase confidence in safety assessment results. Consequently, the project’s results will help nuclear operators to conduct their periodic safety reviews and achieve EU-wide nuclear safety objectives.

Objective

The proposed project intends to translate research to practice through rigorous and efficient methodologies and tools to assess seismic safety of NPP. It also has the aim to innovate current practice by supporting simulation results with experimental data and experience feedback in the framework of Bayesian approaches and machine learning. The research will develop methods to improve the predictability of (non linear, best-estimate) beyond design analyses (design extension earthquakes). The refined seismic PSA provides meaningful support in the decision making process and could be useful for real time expertise of plant safety in case of temporary unavailability of safety relevant equipment or structures. It is also proposed to develop efficient tools to identify major contributors to risk such that efforts to increase safety and resistance are focused on relevant equipment. The outcome will thus increase the reliability of the analyses and in turn increase confidence in the probabilistic and deterministic safety assessment results. The results of this project will then help nuclear operators in their periodic safety reviews and to respond to the high-level EU-wide safety objectives of the amended EURATOM nuclear safety directive (stress tests). The considered accident scenarios will provide input for updating severe accident management guidelines (SAMG).

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
