From September 10-13, 2024, the U.S. Nuclear Regulatory Commission’s (NRC’s) International Regulatory Development Partnership (IRDP) held a 4-day topical workshop for the Nuclear and Radiological Regulatory Commission (NRRC), Kingdom of Saudi Arabia. The workshop was held in Vienna, Austria and focused on how to identify and assess the potential environmental impacts of a nuclear power plant. The workshop included technical presentations, facilitated discussions and interactive scenario exercises by subject matter experts from NRC’s Office of Nuclear Materials Safety and Safeguards and from NRC’s contractor, Advanced Systems Technology and Management, Inc. (AdSTM). The workshop entailed significant discussions by all participants that centered around key technical topics and methods for developing an environmental impact statement for use in evaluating a proposed site.
