Me saying that you’re right doesn’t make sense? A house built using cement isn’t CO2 neutral. A house built using wood uses less CO2, but it isn’t neutral either. A nuclear reactor won’t be CO2 neutral, even if the fission process or the turbines don’t generate any CO2. A wind turbine by comparison, while it won’t have the same output capacity as a nuclear reactor, would use a lot less CO2 to manufacture and assemble.
