The coolants prevent overheating caused by the uranium rods. The process by which nuclear plants work is through the heating of water, which turns into steam and drives the shaft, which in turn creates current. Without coolant the rods would overheat and cause an explosion (like the one seen in Japan, or Chernobyl), thus creating a danger of radiation and causing great danger to the human population.

coolant is used to keep the reactor cool and prevent it from melting down. The amount of cooling that is required really depends on the the amount of heat being put into the coolant.
