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.
Division Spotlight
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.

G7 pledges support for nuclear at Italy meeting
The Group of Seven (G7) recommitted its support for nuclear energy in the countries that opt to use it at a Ministerial Meeting on Climate in Italy last month.
In a statement following the April meeting, the group committed to support multilateral efforts to strengthen the resilience of nuclear supply chains, referencing the goal set by 25 countries during last year’s COP28 climate conference in Dubai to triple global nuclear generating capacity by 2050.

Human error is still one of the main factors threatening the safe operation of nuclear power plants. In view of the deviation of operators’ actions from operating procedures and the impact of implementation of operating procedures on safety functions, this paper proposes the Operating Procedures Supervision System (OPSS). The OPSS monitors operators’ performance deviating from operating procedures, determines the operation state of a nuclear power plant according to realization of the three key safety functions of the plant (reactivity control, radioactivity containment, and residual heat removal), and evaluates the impact of the implementation of operating procedures on the safety state. Although the OPSS supports both off-line and online applications, this paper presents only an example of off-line evaluation to illustrate the method. On this basis, the paper proposes a risk matrix to comprehensively weigh operator action deviation and the impact of operator actions on plant safety functions, which can more finely perceive the changes of system safety status and of operator performance.
