Sodium properties and safe operation of experimental facilities in support of the development and deployment of Sodium Cooled Fast Reactors (NAPRO) (I31024)
Due to the increasing interest in innovative Sodium cooled Fast Reactors (SFRs) and the large number of activities to be carried out for its development, it is necessary to promote an efficient collaboration between organizations involved in SFR programmes at national and international level. Although among fast neutron systems SFR has the most comprehensive technological basis, there are still several inconsistencies regarding sodium physical and thermal properties, and internationally agreed standard rules for designing sodium experimental facilities, good practices and safety guidelines are still missing.In order to address these issues, the IAEA recently established a CRP on “Sodium properties and safe operation of experimental facilities in support of the development and deployment of Sodium Cooled Fast Reactors - NAPRO”.
The first phase of the CRP will be focused on the assessment of sodium properties, and it will lead to a consistent property data set which will be published in the form of a handbook. This work will be carried out by participating Member States through the review and evaluation of the existing available data, the identification of the data gaps and the development of recommendations for experimental programmes to support closing these data gaps.
In connection with this last point, the CRP will also focus on the definition of design rules and best practice for sodium experimental facilities and guidelines for the safe handling of sodium, which poses hazard due to its chemical reactivity with water and air. Outcomes of this part of the CRP will include shared functional requirements, good practices, codes and standards and safety criteria for the design, construction and operation of experimental Na loops in support of innovative SFR.
The CRP represents also an important tool for the education and training of young engineers and scientists in the field of liquid metal coolants technology, even outside the nuclear field.
