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.)

We have investigated the neutron generation characteristics of discharge-type fusion neutron source by experiments and computer simulations for several years. The cylindrical inertial electro-static confinement device used for these studies has been considered to be a point source where neutrons emitted isotropic. The aspect ratio (length divided by diameter) of the device is 1∼2. For neutron applications, a beam shape where neutrons are emitted in a specific direction may be more convenient.In this paper we describe recent results of neutronic calculations for making a beam-type neutron source by increasing aspect ratio of the device and by locating reflecting material around the device. It is found that the increase of aspect ratio of 2∼5 does not strongly affect the neutron flux distribution, but that neutron fluxes in the axial direction becomes 2∼3 times larger than those without reflectors and more than 1 order stronger than the radial direction by adding reflector.
