Realistic Small- and Intermediate-Break Loss-of-Coolant Accident Analysis Using WCOBRA/TRAC

Scaling analysis of an IBLOCA counterpart test between the ATLAS and LSTF facilities

“…In view of this, the USNRC proposed in 2005 the intermediate break as a design basis event for the assessment of the effectiveness of emergency core cooling systems ( 10 USNRC, 1998). Since that time, some experiments related to the effects of these breaks have been conducted and studied to enhance the understanding of the characteristic phenomena, and also to improve the operating efficiency of the new reactor designs ( 11 Bajorek and Petkov, 2001). 12 Addabbo and Annunziato (2012) summarize the major achievements of the extensive research program in LOBI, among which highlights the identification of relevant thermal-hydraulic phenomena in an IBLOCA.…”
