This report, issued by the Working Group on Regulation of New Reactors (WGRNR), on the construction oversight survey is meant to facilitate sharing of information related to the on-site oversight of new reactor construction in various countries, including scope of areas addressed through oversight programmes, level of effort and depth of expertise planned for each area covered, and any special/unique oversight practices. As such, this report could benefit the international community by allowing for benchmarking of practices or providing reference material for countries developing their construction oversight programmes.
