Energy experts discuss nuclear - it ain't good, page-110

Nuclear Power uses more Water than Coal for the same energy produced.
A 2009 World Economic Forum paper provides the
following figures:
"A megawatt-hour (MWh) of electricity from coal
uses 20 to 270 litres of water at the coal mining
stage and an additional 1,200 to 2,000 litres when
the energy in the coal is converted to electricity,
totalling 1,220 to 2,270 litres of water consumed
per MWh. In comparison, nuclear energy uses 170
to 570 litres of water per MWh during the mining
of uranium and production of the reactor fuel and
an additional 2,700 litres per MWh as the energy
from nuclear fission is converted to electricity, for a
total of 2,870 to 3,270 litres of water consumed
per MWh."
