Such cooling water is not used to cool down the reactors, it is used to cool and condense the steam outlet of the steam turbines, in fact it just passes through tubes inside the condenser and then back to the river or lake, or in some plants with cooling towers it passes through the cooling towers before going through the condenser and then back to the river or lake. The water does not come into contact with any radioactivity, but is warmed slightly by heat exchange in the condenser, before returning to the river or lake. So the only effect on the river or lake is to have water returned at a slightly higher temperature than the main body of water. Water taken from a river or lake would have far too many impurities (dissolved solids and organic matter) to be used in the primary or secondary cooling circuits of the reactor, and would go through a demineralising plant before being used for those circuits.

How is electricity produced using nuclear reactors?
water is heated up by nuclear fission and turned into steam, that steam then turns massive turbines which generate electricity.
Name the element once enriched can form the core of a nuclear bomb?
Uranium hexafluoride (hex) is a compound of uranium that becomes a gas when heated. In gaseous form, it can be "enriched". Enriched uranium is needed for research reactors, most non-Canadian power reactors, and bombs.
What are the reactors of nuclear fusion?
In nature, the stars. Man made reactors have not been successful yet, but the most promising are the tokamak types, which are toroidal chambers where a plasma containing the fuel in gaseous form is heated to a very high temperature to produce fusion. You can read more in Wikipedia
An energy source that heats fuel rods is?
Nuclear energy is produced when fuel rods containing radioactive material such as uranium-235 are heated within a nuclear reactor. The heat generated from the fission of the uranium atoms is used to produce steam, which drives turbines to generate electricity.
What do you see when the electrons in an atom are heated?
alarge nuclear explosion
What do Metals and other substances do when heated?
materials usually expand when heated.
Why is steam heated before it goes into a turbine?
Steam direct from a boiler contains microscopic droplets of liquid water. This steam must be superheated to vaporize these droplets. If this is not done the droplets will pit the turbine blades and can cause premature turbine failure. Before the development of zirconium alloy fuel pellet cladding for nuclear reactors the reactor itself could not be operated hot enough to directly superheat its steam. So early designs proposed "hybrid" reactors, using a nuclear reactor to boil the water and make steam and a fossil fuel plant to superheat the steam. But zirconium alloys were developed before any "hybrid" reactors were actually built.
When a stove is being heated does it produce nuclear energy?
no. what would give you that idea?
Which of the following practices that are needed to run a nuclear power plant has a negative impact on both air and water?
The practice of cooling nuclear reactors using water from nearby water bodies can have a negative impact on both air and water. The heated water released back into the ecosystem can increase water temperature, affecting aquatic life, while the release of water vapor during cooling can contribute to air pollution.
When a solid is heated it will usually change to this phase?
When a solid is heated, it will usually change to the liquid phase. This process is known as melting.
How do stars get their heats?
Nuclear reaction by the super heated hydrogen, oxygen and other elements.
How do they collect nuclear energy?
Depends what you want it to do for you. If you want to use it as a weapon, then you don't collect it; you just let it spread around far and wide and cause as much death and destruction as possible. If, on the other hand, you want to use it to generate electricity, you wrap the nuclear reactor in layers of pipes that carry water past it, and you let the nuclear energy heat the water. Then you use the steam or superheated water to run a steam-turbine generator, just as if it had been heated by a coal or oil fire, or by sunshine.
