Management, exploitation and assessment of knowledge in the Severe Accident (SA) field is the top level objective of SEAKNOT. In order to achieve it, some specific goals are pursued:

  • To carry out a critical analysis of the current knowledge on SAs to make recommendations on the way forward to significantly reduce risks associated with existing and forthcoming nuclear technologies (SMLWRs & ATFs).
  • To identify experimental research needs required to support and optimize SA mitigation measures, including an assessment of the current and future EU SA facilities.
  • To strengthen the background and the skills of the young generation on SA through the implementation of an efficient plan to achieve Knowledge and Know-how Transfer (K2T) from senior scientists and engineers.

As a consequence, the major outcomes of the project have been identified as:

  • Phenomena Identification Ranking Table (PIRT) on SA
  • SA Validation Database Directory
  • SA experimental infrastructure network, including a mapping of existing facilities and needs
  • Knowledge spreading (SA Textbook, new editions of SA Phenomenology Course and ERMSAR Conference)
  • Ambitious mobility granting for MSc/PhD students and young researchers

  • Enhance NPP safety outlining the most efficient path for investigation to be conducted in the coming years.
  • Maintain and further expand EC expertise in SA domain.
  • Strengthen the abilities and skills of the workforce responsible for conducting such research.
  • Reinforce education & training activities on SA.

Dissemination actions will have three axes: scientific, supporting the creation and diffusion of high-quality applied knowledge; societal, generating knowledge that support the uptake of innovative solutions to address global challenges, including SDG7 Clean Energy; and economic, facilitating technological development, demonstration and deployment of innovative solutions.

  • Strong benefit from previous EU and non-EU research in the SA field.
  • Collaboration with the NEA/CSNI and IAEA related Working Groups, strong link with the NUGENIA TA2.
  • Creation of a “common space” for SA experts and young  nuclear generations.
  • A reset of needs in SA research based on what’s known, what’s unknown and what’s is safety significant.
  • Upcoming technological and methodological innovation without neglecting the expertise built for decades.
