The ASME/ANS Joint Committee on Nuclear Risk Management (JCNRM) has achieved a significant milestone in the advancement of probabilistic risk assessment (PRA) technology. ANSI/ASME/ANS RA-S-1.4–2021 , Probabilistic Risk Assessment Standard for Advanced Non-Light Water Reactor Nuclear Power Plants, has been approved by the JCNRM, the ANS Standards Board, the ASME Board of Nuclear Codes and Standards, and the American Nuclear Standards Institute.

Rethinking seismic design may be key for making nuclear plant construction affordable.

Nuclear power plants not only provide the nation’s largest source of carbon-free electricity, they also can operate 24 hours a day, 365 days a year to augment intermittent renewables such as wind and solar. Further, studies show that nuclear energy is among the safest forms of energy production, especially when considering factors such as industrial accidents and disease associated with fossil fuel emissions. All said, nuclear has the potential to play a key role in the world’s energy future. Before nuclear can realize that potential, however, researchers and industry must overcome one big challenge: cost.
A team at Idaho National Laboratory is collaborating with experts around the nation to tackle a major piece of the infrastructure equation: earthquake resilience. INL’s Facility Risk Group is taking a multipronged approach to reduce the amount of concrete, rebar, and other infrastructure needed to improve the seismic safety of advanced reactors while also substantially reducing capital costs. The effort is part of a collaboration between INL, industry, the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E), and the State University of New York–Buffalo (SUNY Buffalo).

B. John Garrick, ANS Fellow and member since 1956 and an international authority on quantitative risk assessment, died on November 1 due to complications from a fall. He was 90.
Garrick, a distinguished adjunct professor of materials science and engineering at the University of California at Los Angeles, established his trailblazing theory on risk sciences in his Ph.D. thesis, which contributed to building the foundation of probabilistic risk assessment. Also referred to as quantitative risk assessment, it offers a guide to corrective actions to eliminate threats and to best practices for managing low-probability, high-consequence events resulting from natural and man-made disasters.
Risk-informed and performance-based approaches to nuclear safety have saved money and improved safety for current reactors and have the potential to offer even greater benefits for advanced reactors.

Since the 1980s, the nuclear power industry in the United States has worked to enhance the regulatory framework for nuclear facilities by making it more risk-informed and performance-based (RIPB). This has had some success in improving safety and reducing regulatory burden by focusing resources on the most risk--significant areas and allowing greater flexibility in choosing ways to achieve desired safety outcomes. However, there are further opportunities for the use of RIPB approaches in addressing current regulations and applying implementation tools, and in developing new RIPB regulations and advanced tools to further sharpen the focus on risk and performance outcomes.
