Actually, we don't have enough and never will.  Conservation, conservation, conservation.  Solar, solar and more solar.  The earth is not disposable and we have nowhere else to go.

Depending on the cooling technology utilized, the water requirements for a nuclear power station can vary between 20 to 83 per cent more than for other power stations.

Denver Water Consumption

Denver's 1.1 Million customers use 211 gallons per person per day for a daily total of 232.1 Million gallons per day.  One nuclear reactor's makeup water per day, 15 million gallons. 

When both reactors at the Susquehanna nuclear plant in Pennsylvania operate in summer,  nearly 30 million gallons of makeup water per day (or nearly 21,000 gallons per minute) are needed from the river to compensate for cooling tower drift.

Colorado Electricity Consumption

44,236 MW = About 37 nuclear reactors = 550 Million gallons of water per day = Over twice the daily consumption of water in Denver.  Cost of one reactor = $6 to $9 Billion = cost of 37 reactors = $333 Billion @ $9 Billion each.  $333 Billion = 41,625,000 rooftop water heaters @ $8000 each.  Hot water for bathing, etc. accounts for 13% of household energy consumption = 5,750 MW = 4.8 nuclear reactors = $43.2 Billion = 5.4 Million rooftop water heaters.

Is nuclear power renewable energy?

Nuclear energy uses Uranium as fuel, which is a scarce resource. The supply of Uranium is expected to last only for the next 30 to 60 years (depending on the actual demand). Therefore nuclear energy is not a renewable energy.
