OBJECTIVES

Support deployment of Heavy Liquid Metal (HLM) cooled advanced reactors in Europe

  • Support ALFRED and MYRRHA pre licensing
  • Use maturity of design to take concrete steps towards PSAR

Specific objectives:

  • Use state of the art and design status to do thorough PIRT
  • Focus on key safety issues
  • Validation of safety related components and procedures
  • Outlook towards society
DESCRIPTION OF WORK

Thorough PIRT analyses as starting point for safety evaluation

  • PIRT methodology and development, Reference design and initiating events selection, Numerical evaluation of selected scenarios and creation of R&D roadmap for V&V needs

Safety related experiments for grid and wire spaced fuel assemblies

  • Grid spaced fuel bundle heat transfer characterization in lead : experiments & numerical modelling
  • Wire spaced fuel bundle heat transfer research : generation of a database of experiments , new measurements and modelling of a MYRRHA representative wire spaced fuel bundle and assessment of CFD uncertainty and guidelines for CFD simulations

Validation or development of key Safety related systems

  • Safety rod validation in flowing LBE and numerical modelling
  • Failed fuel pin detection development in HLM via noble gas detection and/or fission products
  • Validation of oxygen control systems in LBE and Pb

Development of NDUS inspection for LFR up to 400°C

Assessment of the impact of HLM cooled systems on society

  • Energy use
  • Social and ethical considerations of advanced nuclear technology

Stakeholder interaction

  • Summer schools and lecture series
  • Stakeholder workshop
