The exploitation, radon, and toxic sludge in the drinking water is one of many sufficient reasons to not go with nuclear (providing copper, niobium and silver mining for PV and wind is less bad which I understand it to be about an order of magnitude better with current tech), but it's important to keep perspective when talking about GHG and criticise based on things that are true. Using your numbers and 3000t of uranium per year at 3.5% burnup you get about 2g of CO2 per exported kWh of Uranium. This is well into 'completely fine' territory and depending on enrichment is cosistent with nuclear lobby claims about being lower emissions than wind. Lower yield uranium mines are worse, and this is a concern if nuclear energy is increased.
