It is hard to believe that 25 years ago, the Reactor Oversight Process (ROP) was born. After evaluating various top-down approaches to assess industry regulatory performance, the Nuclear Regulatory Commission (NRC) worked with the Nuclear Energy Institute (NEI) to develop a risk-informed approach to reactor oversight. This required many public meetings over the course of two years, and pilot testing at eight nuclear power plants. These plants (Salem/Hope Creek, Fitzpatrick, Harris, Sequoyah, Prairie Island, Quad Cities, Fort Calhoun, and Cooper) set the stage for this revolutionary oversight approach that was ultimately accepted and approved by the five NRC commissioners.
The ROP provides a clear framework for combining inspection results with objective performance indicators reported to the NRC to measure the regulatory performance at each U.S. nuclear power plant. The beauty in this approach was its openness, predictability, and objectivity. Over these 25 years, the ROP has slowly evolved as industry performance improved and risk-informed processes were implemented. While industry operating experience and NRC self-assessments informed some improvements to inspections and performance indicators, there is more to do to ensure the ROP keeps serving its intended purpose. The industry and NRC continue to discuss improvements to the ROP and evaluate its effectiveness. This long-running dialogue between NRC, NEI and the public has served all stakeholders well.
Today, the U.S. nuclear fleet operates more safely and efficiently than ever before. While the ROP has come a long way since its inception, it cannot be allowed to stagnate. The ROP must continue to evolve and modernize as the industry’s safety and reliability continue to improve. This is the key to ensuring NRC and industry resources are applied where they contribute the most to safety and public confidence in nuclear energy. Effective and efficient regulation is vital for nuclear power to play a critical role in meeting the Nation’s decarbonization and energy security goals.
