To transfer the heat produced in the fuel to the steam raising units.
water
A lot
Nuclear reactors use coolants (a main coolant) to keep form overheating, of course. They are also used totransfer the thermal energy (heat) generated by a reactor to the steam generating units.
liquid sodium or water
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.
Nuclear Power is used in power stations to produce electricity
The nuclear reaction used in the Bataan power plant is nuclear fission.
Illinois is were nuclear power is most used
Nuclear fission
There is no nuclear power involved in a microwave unless the electricity used to power it is from a nuclear power plant.
It is used for electricity in nuclear power plants == == Nuclear power is used to heat steam which then turns turbines, which generate electricity in nuclear power stations and also to provide propulsion and power on board nuclear submarines.
Nuclear power is successfully used right now.
