ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Nuclear energy: enabling production of food, fiber, hydrocarbon biofuels, and negative carbon emissions
In the 1960s, Alvin Weinberg at Oak Ridge National Laboratory initiated a series of studies on nuclear agro-industrial complexes1 to address the needs of the world’s growing population. Agriculture was a central component of these studies, as it must be. Much of the emphasis was on desalination of seawater to provide fresh water for irrigation of crops. Remarkable advances have lowered the cost of desalination to make that option viable in countries like Israel. Later studies2 asked the question, are there sufficient minerals (potassium, phosphorous, copper, nickel, etc.) to enable a prosperous global society assuming sufficient nuclear energy? The answer was a qualified “yes,” with the caveat that mineral resources will limit some technological options. These studies were defined by the characteristic of looking across agricultural and industrial sectors to address multiple challenges using nuclear energy.

While general guidance for addressing individual elements of the key principles of risk-informed decision making (RIDM) for large commercial nuclear power plants is available in the literature, the implementation of RIDM can still be challenging, whether a mature RIDM framework exists or not. Traditionally, RIDM approaches have focused strongly on the use of risk information, particularly quantitative results from probabilistic risk assessments, with some individual guidance on other key principles such as defense in depth and safety margin. Addressing these different principles in an integrated, balanced fashion that utilizes the strengths of each principle while understanding the impact of uncertainties is not as easily implemented. In fact, the evaluation of each principle in isolation can lead to inadequate input for decision-making purposes, while heavily relying on any single principle can negate the benefits from using a risk-informed approach. This technical note focuses on the specific challenges of the implementation of a truly integrated RIDM (IRIDM) framework and provides specific solutions and detailed discussions and examples. It discusses important clarifications of the key principles of RIDM and their intended implementation, as well as the interrelationships of the principles. A framework for IRIDM is presented that integrates the information that needs to be considered, documented, and communicated to decision makers.
