Division Spotlight
Reactor Physics
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.)

Two space propulsion systems, which are called K2H (KBSI-KAIST-Hanyang University) and DiPS (Diversified Plasma Simulator) devices, are being developed in parallel to explore the space propulsion parameters and optimal helicon operation conditions with the concept of VASIMR (Variable Specific Impulse Magnetoplasma Rocket). Both devices utilize the open-ended magnetic configuration. K2H has three regions such as helicon source, ion cyclotron resonance heating (ICRH), magnetic nozzle and expansion regions. DiPS is the space plasma simulator and composed of three major sections: helicon plasma source, extraction region and space simulation region. Helicon plasmas are generated for both devices by 13.56 MHz rf power using M=+1 right-helical antenna at pressure of several mTorr. Initial plasma parameters such as density, temperature, and drift velocity were measured by a laser induced fluorescence (LIF) system and a fast scanning electric probe system with an rf-compensated Langmuir probe and a Mach probe at ICRH and magnetic nozzle region. The results are given as follows: plasma density n = 1011 - 1013 cm-3 (K2H) and 1012 - 1013 cm-3 (DiPS), electron temperature Te = 3 - 9eV (K2H) and 2 - 4 eV (DiPS), ion temperature Ti = 0.144 - 0.164 eV (K2H), and drift velocity vd = 0.8 - 1.55 km/s (K2H). A simple analysis of the results is provided.
