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.)

Gaps exist between the first wall/shield (FWS) modules of ITER to allow for fitting by remote handling equipment. Simplified three-dimensional models were used at the top and mid-plane locations to analyze gap streaming. Heating, helium production, and fast neutron fluence were examined at the front of the vacuum vessel and the magnet for both straight and stepped gaps. In addition, total nuclear heating values in the inboard magnet and central solenoid were examined for straight and stepped vertical gaps and for combined horizontal and vertical straight gaps. The results show significant radiation streaming effects that are more pronounced for fast neutron fluence and helium production. Furthermore, it was found that stepping the gap significantly reduces the local peaking, but has little effect on the relative average values of radiation effects. The results also show increases up to 75% in total magnet heating at the inboard mid-plane location for a straight 2 cm combined vertical and horizontal gap.
