The Byron and Dresden nuclear plants, which supply 30% of Illinois CO2-free energy will power down in 4 months without government intervention. These plants, which are licensed to operate well into the future, are uneconomic amid deregulated energy markets and the cheap natural gas unlocked by the fracking revolution. Keeping existing nuclear plants operating in the northeast USA has a carbon abatement cost of $25/ton of CO2. This is half the social cost of carbon in Biden's proposed carbon tax of around $50/ton.    By comparison, rooftop solar costs $800/ton and utility wind and solar $300/ton. As Robert Bryce has pointed out, solar gets 250x and wind 160x more in federal tax credits than nuclear per unit of energy produced.
In a number of jurisdictions, legislators have recognized the important contribution of nuclear to grid resiliency, decarbonization, and clean air with measures like Zero Emissions Credits. In some areas these subsidies have paradoxically decreased the cost of electricity. 
The Biden administration has committed itself to a decarbonized power system by 2035. There are mixed signals from his administration of their perception of the importance of nuclear energy to have a chance at achieving this ambitious goal. Senator Joe Manchin has urged Biden to support the continued operation of the US fleet and Jennifer Granholm, the DOE secretary, has floated the idea of federal subsidies to keep existing nuclear plants open. However, firm commitments to creating effective policy that can preserve the 50% of all US clean energy that nuclear provides are lacking. If Byron and Dresden are allowed to close, they will be replaced largely by imported fossil fuels with their accompanying pollution and carbon emissions.
In this context Madi and a group of committed volunteers are leading an all-out effort to save the Byron and Dresden Nuclear plants, the zero-air pollution and zero-emissions energy they provide, and the thousands of union jobs that are on the line. Sadly they are opposed by environmental NGOs, like the NRDC, which recently danced on the grave of Indian Point, which had provided 2.5x the amount of zero-carbon power as the entire New York wind and solar fleet.
