Should nuclear energy be promoted on a fast-track in order to reduce the emissions of carbon dioxide into the atmosphere?

From Internet:

One of the few pros of nuclear power is the relatively low emission of carbon dioxide (CO2), one of the major causes of global warming. For this reason, nuclear power has been proposed as "the" method to mitigate the effects of climate change.

Some of the nuclear lobbyists even claim that the production of electricity by atomic energy does not emit any CO2. But this is nonsense. Whenever a plant is built to produce electricity, CO2 is emitted. So even the production of electricity by renewable resources like solar power, water, wind, or biomass does release some CO2.

To calculate the amount of CO2 being released, the whole life cycle of a plant as well as the production of the raw energy has to be looked at. For a nuclear power plant, this includes construction, operation, maintenance and refurbishments, decommissioning and dismantling of the reactor. Of the same importance is the nuclear fuel: Recovery of uranium from the earth’s crust, extraction of uranium from ores, enrichment and chemical treatment, transportation as well as disposing of used fuel.

From this, what should be done?
