If everything is operating normally, we won't see anything radioactive in the water from a nuclear power plant. That water will have heat energy in it as water is used to cool things in the plant. Some systems will be present to limit the amount of heat that is put into the water, but some heat will appear in the effluent water stream.
0, Ecuador has no nuclear energy plants.
Most of it does, but some comes from weapons manufacture as well
Nuclear energy comes from nuclear power plants. Inside the power plant, the workers split Uranium atoms which release heat. Then they release water on the heat which causes steam. the steam rises and turns turbines which then release electricity.
Both fossil fuel plants and nuclear plants use heat to produce steam by heating water. This steam is then used to drive turbines that generate electricity. Fossil fuel plants heat water by burning coal, oil, or natural gas, while nuclear plants use nuclear reactions to produce heat.
In the US, about 19 percent of total electricity comes from nuclear plants. Worldwide it is about 16 percent
Terrain hardly comes into it. However nuclear plants should not be built in earthquake zones, and they need adequate cooling water (like any power plant does)
About 19 percent
Illinois has several nuclear power plants (see link below) with a total generating capacity of 11,263 MWe. I don't have details of other types of power plants in the state.
Geothermal energy comes from the Earth's internal heat, not from nuclear power plants. It involves tapping into the heat stored beneath the Earth's surface to generate electricity or for heating applications.
Basically, nuclear power plants use the heat from a nuclear fission reaction to boil water The steaming water then turns a turbine that generates electricity.
Nuclear energy as obtained in nuclear reactor power plants comes from the fission or splitting of the nuclei of uranium and plutonium. It is not a chemical burning process and does not need any other elements to make it happen.
The negative effects of nuclear power plants on sea life is very limited as the sea water used for cooling is fully separated from the nuclear fuel. In addition, the regulations require that the sea water temperature rise due to its use for nuclear plants cooling should exceed 5 degrees centigrade. Many swimming beaches are located close to the nuclear power plants sites.
