Abstract

CSNI has a long-lasting history in nuclear thermal-hydraulics. This was established during the 70’s decade in previous century and testified by milestone type of reports and Specialists Meetings issued or held in the last 50 years . Namely, five groups of key reports can be distinguished: The SOAR: TPCF, TECC, BWRS, and, more recently, the Scaling (and the passive System) reports; The validation reports: a couple dozen ISP on thermal-hydraulics and the SET and the ITF related Validation matrices reports, including identification of phenomena. The uncertainty related reports: more details in the ‘justification’ row below. The CFD application & advancement activities, including synthesis views, conference documentation (noticeably CFD4NRS) and pioneering activities (e.g. the uncertainty in CFD prediction) Documentation of OECD project starting from LOFT: more details in the ‘justification’ row below. Specialists Meetings in the area of thermal-hydraulics are listed under the row ‘justification’ below. Furthermore, a specific activity has been started in 2004 dealing with transfer of competences. This is called THICKET. Thus one ‘indirect’ objective is to maintain the competence of CSNI in the area of thermal-hydraulics. The main ‘direct’ objective is to discuss the achievements and defining the needs of safety research in nuclear reactor accident thermal-hydraulics. In particular: •To report on the major achievements accomplished in recent years. •To discuss the maturity of nuclear thermal-hydraulics for evaluating safety of existing reactors, identifying strengths and drawbacks of the current analysis approaches. •To define the needs and priorities of research on safety-related thermal-hydraulics, particularly under accident conditions.
