Nuclear makes little sense for climate targets. The construction is too expensive and too slow - allocating capital to nuclear ends up slower than allocating the same capital to renewables for hitting climate targets. If you look at reports of lifetime costs for utility scale energy, Nuclear is the most expensive and will likely remain so for the foreseeable future. Solar and wind is already 3-4x cheaper than nuclear, and by the time the decade is out it will likely be 10x cheaper even with attendant storage.
