If we built nuclear in addition to renewables, the transition would go faster.
According to all the studies, no it won’t. Nuclear takes far longer to build, in the meantime we’re still using fossil fuels. While we may need to use fossil fuels to back up renewables intermittently in the short term, we would still be using far less than we would waiting for nuclear. Nuclear costs a lot more, and the amount of money the government has to subsidise construction is finite - for every MW of nuclear you could build more MW of renewables, more quickly and for the same cost. Renewables are cheap, proven and available now.
We need nuclear eventually, as part of a complete portfolio of energy production. However we need to get off fossil fuels far more urgently, and nuclear doesn’t care about urgency.
