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.

Ohio Senate votes to repeal nuclear plant subsidies
After months of unsuccessful efforts by Ohio lawmakers to contend with the fallout from H.B. 6—the now-infamous nuclear subsidies bill signed into law in 2019—the state’s senate on March 3 passed a measure, S.B. 44, to repeal those subsidies. The vote was 32–0.
For those who may need reminding, federal prosecutors on July 21, 2020, arrested Larry Householder, then speaker of the Ohio House, and four lobbyists and political consultants for their involvement in an alleged $61 million corruption and racketeering scheme aimed at guaranteeing passage of H.B. 6, whose subsidies had kept Ohio’s Davis-Besse and Perry nuclear power plants from premature closure.
H.B. 6 established a seven-year program to charge the state’s electricity consumers fees to support payments of about $150 million annually to the plants’ operator, Energy Harbor Corporation, then known as FirstEnergy Solutions (FES). FES had announced in March 2018 that it would be forced to close Davis-Besse and Perry without some form of support from the state. (The payments to Energy Harbor were blocked last December by an Ohio Supreme Court injunction, which complemented an earlier lower court ruling.)

An inertial electrostatic confinement (IEC) fusion device driven by a ring-shaped built-in ion source is proposed and designed aiming at a reduced operating gas pressure in order to explore a possibility of a drastic enhancement in the fusion reaction rate in the envisaged beam-beam collision regime. In the present scheme ions will be extracted from a ring-shaped magnetron discharge plasma toward an IEC cathode grid placed concentrically at the center. A prototype ion source showed an accessible pressure of 5 mPa, which is hundreds times as low as the conventional glow-discharge-driven IEC. Dependence of the ion source current and extraction efficiency on the central IEC cathode voltage was studied by prototype experiments and numerical calculations. An IEC device with a built-in ion source was then designed based on these results. The expected IEC grid current is ~0.4 mA at 5 mPa, where observation of the beam-beam fusion contribution is anticipated.
