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.)

There are continuing theoretical activities to understand experimentally observed unusual (not explained by the ideal MHD theory) stability of the Field Reversed Configuration (FRC) plasmas and the existence of the FRC-equilibria as a relaxed state. FRC plasma sustainment system based on high energy particles are proposed to exploit their possible good confinement. It is also proposed to realize pulsed fusion system with the particle density between continuous systems (~1020/m3) and inertial systems (~1031/m3); the magnetized target fusion (~1026/m3) and the pulsed high density systems (~1023/m3). With the aim of overcoming the limitation in producing large scale, continuous FRC plasma, theoretical and experimental studies are intensively carried out on the FRC plasma formation and/or sustainment by the rotating magnetic field (RMF). The technology of the translation made it possible to apply standard method of sustaining the plasma - the neutral beam injection and the wave - to the theta pinch produced FRC plasma. Except for the duration, this plasma has the best performance (density and temperature) and low frequency wave is successfully induced and propagated deep in the FRC plasma.
