in TFA the James A. FitzPatrick Nuclear Power Plant is arguably at the end of its useable lifespan (30-40 years.) Coincidentally so is the Ginna plant. for those keeping track of the joke that is Nuclear Regulation in america, both have been given a 30 year extension despite having gone from megawatt to gigawatt in their installed versus actual capacity. the reactor cleanup cost would likely go to Entergy...who would either declare bankruptcy or drag the government and mohawk energy (a prior owner) into court over potentially responsible party definition as that would determine who has to clean things up. if Mohawk were to declare themselves insolvent, or the PRP could not be identified in court, the entire site would become an orphan share. that means no one has to clean it up but the taxpayer out of the congressional general fund. its lemon socialism.
Entergy likely understands the cost to litigate its way out of a superfund cleanup is way cheaper than actually cleaning a nuclear site and once its absolved of cleanup, it can focus on investing in the gas fracturing movement, which is likely vastly more lucrative than maintaining 40 year old nuclear sites.
