Nuclear waste is a problem that stops the argument in favour of nuclear energy in its tracks. Using a controlled nuclear reaction as a substitute for oil and gas just substitutes the pollution of nuclear waste for carbon pollution. Until there is a secure way to manage nuclear waste with a half life of 125,000 years, we are just leaving the disposal/storage problem for our grandchildren. We can’t secure nuclear waste for 100 years, let alone 125,00. The nuclear industry was stopped back in the seventies because of the nuclear waste problem. They have bided their time, waiting for the people who convinced the world not to go nuclear to die. Most of them have… so here’s the nuclear industry trying again. It was an insoluble problem then and it is an insoluble problem now. The planet already has an existential threat on its hands. We don’t need to resurrect another.
