Nuclear Called a Lesser Evil than Fossil Fuels

The time has come for a fresh approach to nuclear power in the 21st century." Currently, nuclear energy provides around a fifth of US electricity demand. Globally, that figure is slightly lower, with 30 countries hosting nuclear reactors that provided around 12 percent of worldwide electricity production, as of 2011.

How Does Nuclear Energy Affect the Environment?

Apr 25, 2018Nuclear power has been called a clean source of energy because the power plants do not release carbon dioxide. While this is true, it is deceiving. Nuclear power plants may not emit carbon dioxide during operation, but high amounts of carbon dioxide are emitted in activities related to building and running the plants.

How does a nuclear power plant work?

Jun 13, 2019In nuclear power plants, the chain reactions are very carefully controlled so they proceed at a relatively slow rate, just enough to sustain themselves, releasing energy very steadily over a period of many years or decades. There is no runaway, uncontrolled chain reaction in a nuclear power plant.

How Nuclear Power Works

Nuclear reactors. After the steam is used to power the turbine, it is cooled off to make it condense back into water. Some plants use water from rivers, lakes or the ocean to cool the steam, while others use tall cooling towers. The hourglass-shaped cooling towers are the familiar landmark of many nuclear plants.

Disadvantages of Nuclear Power

Nuclear power is generated from a metal called uranium. Uranium is mined in places such as Australia, Argentina, Canada, Brazil, China, France and many other countries. The uranium is used to create controlled nuclear reactions called nuclear fission. Nuclear fission gives off a tremendous amount of heat which is used to heat water to create steam.

Nuclear Power Plants

Nuclear power comes from nuclear fission. A bundle of fuel rods, some with hundreds of rods, is called a fuel assembly. A reactor core contains many fuel assemblies. The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine.
