Does nuclear energy produce more CO2 than renewable energies?

Generally no; values are comparable and depend on the technology.

Over its lifecycle, nuclear has very low emissions. The medians reported in IPCC/UNECE comparisons are of the same order of magnitude as wind and lower than many estimates for photovoltaic solar, although ranges depend on site, enrichment, construction, and capacity factor. Saying that nuclear produces 'more CO2 than renewables' as a general rule is not supported by the main LCA databases.
