Generic Safety Issues for Nuclear Power Plants with Pressurized Heavy Water Reactors and Measures for Their Resolution

This report covers generic safety issues (GSIs) judged to be of significance to Member States, based on a consensus process. The GSIs for pressurized heavy water reactors (PHWRs) compiled in this report reflect the broad experience of Member States in resolving safety concerns and in maintaining improvements to current practice. As can be seen from the actions taken in Member States with respect to the appropriate technical solutions, most issues have been successfully addressed. Those issues that have been generally resolved by Member States or concluded to be of low safety significance have not been included in the compilation. This report will be a valuable resource in identifying areas, especially for enhanced designs of PHWRs, where safety upgrades should be considered.
