In-vessel coolability and retention of a core melt
Nuclear Engineering and Design, 1997 Abstract The efficacy of external flooding of a reactor vessel as a severe accident management strategy is assessed for an AP600-like reactor design. The overall approach is based on the risk oriented accident analysis methodology (ROAAM) and the assessment includes consideration of bounding scenarios and sensitivity studies, as well as arbitrary ...

Two- and three-dimensional experiments for oxide pool in in-vessel retention of core melts
Nuclear Engineering and Technology, 2017 To investigate the heat loads imposed on a reactor vessel through the natural convection of core melts in severe accidents, mass transfer experiments were performed based on the heat transfer/mass transfer analogy, using two- (2-D) and three-dimensional (
