Well the renewables targets keep getting pushed out so nuclear is very much part of the solution. Anyone who thinks we can get to zero carbon by 2050 (even though that is highly unlikely) is not dealing with reality. The global population is still rising maybe going to 10billion people.

This is a multi decade transition, massive investment and infrastructure construction that's not going to happen by arbitrary targets dreamed up by politicians and bureaucrats.
