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.
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Maintaining RIPB in commercial LWRs
The new standard ANSI/ANS-30.3-2022, Light Water Reactor Risk-Informed, Performance-Based Design, has just been issued by the American Nuclear Society. Approved by the American National Standards Institute (ANSI) on July 21, 2022, the standard provides requirements for the incorporation of risk-informed, performance-based (RIPB) principles and methods into the nuclear safety design of commercial light water reactors. The process described in this standard establishes a minimum set of process requirements the designer must follow in order to meet the intent of this standard and appropriately combine deterministic, probabilistic, and performance-based methods during design development.

The ARIES Team currently is engaged in an effort called the "ARIES Pathways Study". The goals of this study are to evaluate remaining R&D needs toward practical fusion energy and to identify and evaluate possible "next step" devices to bridge the gap between ITER and an attractive power plant. In order to evaluate our current state of readiness and remaining R&D needs, we adopted a methodology called "Technology Readiness Levels". We defined a quantitative set of readiness levels that encompass the major technology challenges for fusion energy development, and have applied them to evaluate our current level of advancement and R&D needs for an advanced tokamak power plant concept based on recent ARIES designs. Results of the evaluation and recommendations for future R&D are presented.
