Abstract
Following the ISP [see below for acronyms] proposal made by UNIPI to OECD/NEA/CSNI in 1985[proposal given below under quotation] and the first ISP 21 Workshop held in Marina di Grosseto, 1986, the second and final Workshop for the international activity was held in Calci (Pisa geographical region) in 1989. “The document deals with the proposal made by UNIPI to the OECD/NEA/CSNI (Organization for Economic Cooperation and Development / Nuclear Energy Agency / Committee on the Safety of Nuclear Installations) to perform an International Standard Problem (ISP), which was, later on, called ISP 21. This was at the time the first ISP proposed by Italian Institutions dealing with an Integral Test Facility (ITF). ISP 21 was a Small Break Loss of Coolant Accident (SBLOCA) scenario expected to occur in Boiling Water Reactors. One key feature of the proposed experiment was its Counterpart-Test feature which allowed the comparison with similar experiments performed in the FIST facility (available in US, San Jose, General Electric) and the ROSA-III facility (available in Japan at the JAERI research center of Tokai-Mura).
