The OECD/NEA ROSA-2 project aims to resolve key light water reactor (LWR) thermal-hydraulics safety issues highlighted from the first phase of the project, by using the ROSA/large-scale testing facility (LSTF) at the Japan Atomic Energy Agency.
In particular, the ROSA-2 Project will focus on the validation of simulation models and methods for the following complex phenomena of high-safety relevance for thermal-hydraulic transients in design basis events (DBE) and beyond-DBE:
The experimental program is intended to provide a valuable and broadly usable database to achieve the above cited objectives. The OECD/NEA ROSA-2 Project consists of six LSTF experiments that mainly include two groups of experiments which are intermediate break loss-of-coolant (LOCA) accidents and steam generator tube rupture (SGTR) accidents. One of the six experiments may be directed to a different target following a discussion with the project partners. The OECD/NEA ROSA-2 Project is scheduled to run from 01 April 2009 to 31 March 2012.
The project is supported by safety organisations, research laboratories and industry from the following countries: Belgium, the Czech Republic, Finland, France, Germany, Hungary, Japan, Republic of Korea, Spain, Sweden, Switzerland, the United Kingdom and the United States.
