>Nuclear power is sometimes described as being free of greenhouse gas emissions, and that’s true of the nuclear fission reactions themselves. But here is a list of all the stages of the nuclear power cycle at which greenhouse gases are emitted: uranium mining, uranium milling, conversion of uranium ore to uranium hexafluoride, uranium enrichment, fuel fabrication, reactor construction, reactor decommissioning, fuel reprocessing, nuclear waste disposal, mine site rehabilitation, and transport throughout all stages.

>During these stages, greenhouse gases are emitted directly (for instance, by trucks) but also indirectly (such as through the use of materials such as steel and cement, which are manufactured using emissions-intensive processes). [0]

I would hazard the site simply doesn't want to be disingenuous at all, and provide the facts, which I applaud! I do not consider this an argument against nuclear power per-se, as stated: it is still much lower carbon than burning FF directly as the plant's power source.
