NEA Advanced Thermal-hydraulic Test Loop for Accident Simulation Project Phase 2 (ATLAS-2)

This project is a follow-up to the NEA ATLAS Project that was carried out between April 2014 and March 2017 by Korea Atomic Energy Research Institute (KAERI), Korea. That project was referenced in the The Fukushima Daiichi Nuclear Power Plant Accident: OECD/NEA Nuclear Safety Response and Lessons Learnt report as one of the three new joint projects based on existing research facilities which address safety issues related to the accident.
Phase two of the ATLAS project is aimed at topics of high safety relevance for both existing and future nuclear power plants that have been identified by the participants. The following topics will be addressed:

The experimental programme is devised to allow for an open test, which is to be defined in consultation with project members and which might cover the above issues or other safety-relevant issues. The experimental programme is to provide an integral-effect experimental database, which will be used to validate code predictive capability and accuracy of models. The experimental programme and associated analytical activities will help to create a group among OECD/NEA member countries which share the need to maintain or improve the technical competence in thermal hydraulics for nuclear reactor safety evaluations.

Participants

The ATLAS-2 project will be supported by the safety organisations and industry in the following countries: Korea, Belgium, Czech Republic, China, France, Germany, Spain, Switzerland, United Arab Emirates and the United States.
