  1. thet are all over their 40 year lifespan limit and are leaking underground and have been for years.They all need to be taken offline,emptied out and decommissioned.We can use the outrageous money it cost to run them and apply it to geothermal and solar/wind technologies. Most people don't know that nuclear was never able to pay for itself.It used so much electricity to run,that it was never able to break even.The special interests that kept them running all these years did so by way of government subsidies and polluted the environment for nothing other than money.
