[en] The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) is the country’s primary authority on radiation protection and nuclear safety. ARPANSA aims to promote safety, security, and emergency preparedness through efficient and effective regulation of nuclear installations, controlled facilities, and radiation sources. Recent initiatives to improve regulation by ‘cutting red tape’ and reducing regulatory burden have been introduced. ARPANSA’s Regulatory Delivery Model emphasises the key elements to good regulation and describes initiatives such as baseline inspection schedule, Performance Objectives and Criteria, and performance deficiencies. These and other initiatives have streamlined inspection efforts, increased risk-based oversight and risk-informed decision making, leading to increased efficiencies for both regulator and licence holder. In addition, ARPANSA has introduced 12 key performance indicators in its self-assessment of regulatory performance against the Australian Government’s Regulator Performance Framework. (author)
