To summarize: the nuclear produces much co2 but it is undoubtedly its least worrying waste ...
REVOICI these figures

Those of hydraulics also AMHA when we know the number of m3 concrete it takes to build a dam ... their life is certainly important (more than a nuclear power plant) but the maintenance must also cost in CO2 ...
And in fact, in a well done study,
no direct emission should be zero, since the operation of the technologies indirectly emits CO2 (unless it is included in the LCA of this table?) ... 2 examples:a) The demand wind of the regular maintenance, whether preventive or curative, it requires maintenance teams ... (it is the solar that needs the least maintenance in fact)
b) A nuclear power plant of 2 reactors (Fessenheim

The average French work is about 25km, so it is 50 000 km per day traveled ... 120gr / CO2 ... 6 tons of CO2 per day NOTHING for the movement of employees to operate the plant. ..this is certainly very little compared to the electrical energy produced each day (23 GWh ... 0.25 g / kWh) but it is not zero and it was an easy example to demonstrate.
There are dozens of other posts to consider, see the link above ...
In short believe that the nuclear 0 emission CO2, it's the same as believe in the electric car 0 global emissions ... and the nuclear is no longer, either, the energy independence of the France since we closed the last uranium mine in France (year 80 ...)
