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.
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

The Civil Nuclear Credit Program: An overview
Officially established on November 15, 2021, with the signing of the $1.2 trillion Infrastructure Investment and Jobs Act—aka the Bipartisan Infrastructure Law, or BIL—the Department of Energy’s Civil Nuclear Credit Program was designed to give owners/operators of commercial U.S. reactors the opportunity to apply for certification and competitively bid on credits to help support the continued operation of economically troubled units. Finally, the federal government, and not just certain farsighted state governments, would recognize nuclear energy for its important grid reliability and decarbonization attributes.

The outlet plenum of a pebble bed modular-type gas-cooled nuclear reactor was optimized using three-dimensional Reynolds-averaged Navier-Stokes analysis and optimization techniques. A shear stress transport turbulence model was used as a turbulence closure. Two design variables for the optimization were selected: dimensionless displacement on the horizontal line and the angle of rotation about the center of gravity of the roof support block. The objective function was defined as a pressure drop between the inlet and the outlet of the outlet plenum. Latin hypercube sampling was used for selecting experimental design points within the design space. The objective function value was obtained at each design point through numerical analysis. The results show that the optimal design significantly improved the performance of the outlet plenum with respect to pressure drop. Through optimization, the pressure drop decreased by 11.8% compared to the pressure drop under the reference geometry.
