Availability Notice


Six non-nuclear and five nuclear large break loss-of-coolant experiments were performed in the Loss-of-Fluid Test (LOFT) PWR facility at the Idaho National Engineering Laboratory. These experiments provided a large amount of data necessary for evaluation and refinement of reactor system-computer codes and had major impact on the understanding of large break loss-of-coolant accidents. An overview of these nuclear large break experiments performed under NRC and OECD LOFT programs is given and the major research results are presented.
