Thermosyphoning PhenomenaλλλλOccurs in the absence of forced flow in the primary heattransport system (i.e., loss of PHT pumps due to loss of ClassIV power)Decay heat generated by the fuel is transported to the steamgenerators by natural circulation (thermosyphoningphenomena)Thermosyphoning is defined as the natural circulation in thePHT induced by the difference in coolant densities in thevertical sections of the:– reactor inlet pipes and– reactor outlet pipesThe thermosyphoning flow through the core is sufficient tocool the fuel24-May-01 <strong>CANDU</strong> safety - #4 - <strong>Thermalhydraulic</strong>s.ppt Rev. 0 6
