OECD CSNI State-Of-the-Art-Report on thermalhydraulics of Emergency Core Cooling Systems: Review of the Operation of Experimental Facilities", OECD-CSNI Report SINDOC (89)101, Paris (F), 1989

As Italian representative inside the thermal-hydraulic task group of Organization for Economic Cooperation and Development (OECD) / Nuclear Energy Agency (NEA) / Committee on the Safety of Nuclear Installations (CSNI), the current author contributed to a preliminary activity which ended up in an OECD publication. The framework of the activity is assessment and validation of system thermal-hydraulic codes. The present report deals with the assessment of the capabilities of experimental facilities available in the world (OECD Countries) for the validation of computer codes in nuclear reactor safety. The scaling issue and the quality of instrumentation and documentation of results are at the focus of attention.
