The information provided is based on the feedback from technical experts from Canada, France, Finland, India, the Islamic Republic of Iran, the Russian Federation, and the United States of America. There is, however, still no common understanding of DECs due to the complexity of phenomena and insufficient experimental data. This publication identifies current approaches of IAEA Member States with active nuclear power programmes and discusses the regulatory perspective and technical rationale. It attempts to find common practices and possible areas for harmonization of the main rules related to the analysis of DECs with core melting for new water cooled reactors, including their selection for the safety demonstration. 410 0$aIAEA-TECDOC. 606 $aPressurized water reactors 615 0$aPressurized water reactors. 676 $a621.48336 712 02$aIAEA, 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910794416603321 996 $aCoolant chemistry control and effects on fuel reliability in pressurized heavy water reactors$93739029 997 $aUNINA
