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.)

The development and optimization of the fueling method enable us to increase and sustain the plasma density. In the present plasma experiments, three major ways, which are gas puff, NBI and pellet injection, are used for particle supply to keep or increase the plasma density. In the GAMMA 10 tandem mirror, the study of particle fueling has been carried out in term of high performance plasma production. In the central cell of GAMMA 10, a pellet injector, a neutral beam injector and some gas puffers have been installed. To clarify the feature of particle fueling method and compare with each other, the calculation with simple slab model is applied to the experimental results, and the effects of the particle fueling method on the plasma parameters are compared experimentally. As the results, it is found that the change of the electron density and H line emission profiles caused by pellet injection has the peak near the center of the plasma and the change of the density and temperature occurs quickly. The change of the plasma parameters caused by the gas puff mainly occurs in the peripheral region of the injection side. And the change of the plasma profiles occurs in core region of the plasma and the plasma temperature is sustained during several ms when the particles are fueled by the neutral beam injection.
