Nuclear plants have to be constructed, uranium has to be mined, processed and transported, waste has to be stored, and eventually the plant has to be decommissioned. All these actions produce carbon emissions.
And of the places where these plants go; and where the uranium comes from..
Another question has to do with the sustainability of the uranium supply itself. According to researchers in Australia at Monash University, Melbourne, and the University of New South Wales, Sydney, good-quality uranium ore is hard to come by. The deposits of rich ores with the highest uranium content are depleting leaving only lower-quality deposits to be exploited.3 As ore quality degrades, more energy is required to mine and mill it, and greenhouse gas emissions rise. "It is clear that there is a strong sensitivity of ... greenhouse gas emissions to ore grade, and that ore grades are likely to continue to decline gradually in the medium- to long-term," conclude the researchers.

The hidden cost of Britain’s new generation of nuclear power could be the destruction of the Kalahari desert in Namibia and millions of tonnes of extra greenhouse gas emissions a year, the Observer has discovered.=
The desert, with its towering sand dunes and spectacular lunar-like landscapes, is at the centre of an international uranium rush led by Rössing Uranium, a subsidiary of the British mining giant Rio Tinto, and the French state-owned company, Areva, which part-manages the nuclear complex at Sellafield and wants to build others in Britain……………

And as I mentioned before, it is what is artfully left unsaid by politicians we need to know most

The UK has justified its planned expansion of nuclear power partly on the basis that it provides low-emission energy. However, the energy used in drilling, blasting, excavating, separating and transporting the uranium to Britain are not taken into account.
Documents seen by the Observer suggest the mines would initially consume about 53 million cubic metres of water a year, more than 75% of the water presently supplied by the Namibian state water company. The water will need to be pumped more than 56km to the mines from the coast. The proposed expansion of the uranium mining would create mountains of waste radioactive sand.
And; Something to watch...
This was just one nuclear plant...

Local and state governments, federal agencies, and the electric utilities have emergency response plans in the event of a nuclear power plant incident. The plans define two “emergency planning zones.” One zone covers an area within a 10-mile radius of the plant, where it is possible that people could be harmed by direct radiation exposure. The second zone covers a broader area, usually up to a 50-mile radius from the plant, where radioactive materials could contaminate water supplies, food crops, and livestock.
Food for thought,
Seems power plants are having some difficulty today..
Omitted from the above, we see this was going to be a gas powered plant.
