Thermal pollution is caused by the release of hot water back into bodies of water. This hot water alters living conditions for the aquatic creatures that inhabit the waters. These bodies of water become oxygen deprived because warmer water does not hold as much oxygen. This disrupts the ecological balance of species. Many safety precautions are taken to ensure that the nuclear reactors do not overheat and thus explode.
Plants have sensors that help plant employees monitor the temperature, pressure, and water level.
If anything is suspected to be out of balance, the plant is automatically shut down. To protect the outside world from the release of radiation, several measures have been taken. The radioactive bi-products are kept inside the fuel pellets, which are enclosed in a special metal casing. All of these rods are contained inside a large vessel with eight-inch thick walls. Because people all around the world fear nuclear warfare, the production of nuclear power is often questioned.
