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.
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.)

As the main additional heating system and the only means to heat the ions, ion cyclotron resonance heating (ICRH) plays a central role in plasma scenario developments on Tore Supra. Conversely, the specific focus of Tore Supra toward long-duration discharges places its heating system in an original position in the ion cyclotron community. High-power long-pulse requirements motivated innovative design choices and operational methods. Over long pulses, the physics of rf waves in the plasma edge early emerged as a crucial issue that was abundantly studied and benefited from original diagnostic techniques, some of which still remain unique in the magnetic fusion community. This paper reviews ICRH technology and physics on Tore Supra, from the generators and antennas to the central plasma via the scrape-off layer. Emphasis is put on the experience gained over 20 years of experimental and theoretical activity. Lessons are drawn for next-step devices.
