Energy - Nuclear Energy Can we live without energy? Naturally no! People and animals need energy to survive. Food is the source of energy. Carbohydrates “are burned” in the body. Energy, CO2 and water are produced. Agriculture production needs also energy (for seeding, production and transport). Modern life is always in small or bigger cities. If we haven´t any energy, we wouldn´t have our usual modern life style. Demand on energy is increasing If the world population is increased, more energy is needed. Because more people…

Nuclear Energy

Technological Aspects On a fundamental level, nuclear power works like coal or gas power plant, as in it heats water and the resulting steam turns a generator. But as opposed to gas or coal, the heat does not come from burning fuel, but instead, it is the excess heat from nuclear fission reactions.

The reactor chamber consists of the reactor block, the fuel cells (usually uranium) and regulator rods, which, depending on their insertion depth, slow or even stop the continuous fission reaction. This whole construction is usually flooded with water, which gets pumped out through a heat exchanger and then led back into the chamber.

A secondary water cycle is heated up this way, so all the contaminated water stays in the chamber cycle. This heat exchange can have multiple stages, with only the last stage actually being allowed to evaporate and turn the generator turbines.

There are many types of nuclear plants but they all work this way with slight deviations depending on their type. The most common types are Pressure Water Reactor, Heavy Water Reactor, Quick Incubator Reactor, and Gas-Graphite Reactor. The last one, the GGR is a bit of an outlier using radioactive graphite dust as fuel, essentially using uranium mining waste


Environmental Impact

Nuclear power has been called a clean source of energy because the power plants do not release carbon dioxide.While that is true the process of mining uranium still releases high amounts of carbon dioxide into the environment

When it comes to cooling a nuclear power plant often times river or ocean water is used. The used water is then returned to about 25 degrees warmer which kills many species of fish and plant life.

The most important concern regarding the impact of nuclear power is radioactive waste though. Nuclear waste needs to be stored properly because it stays radioactive for many centuries to come. But because proper storage is expensive (especially up front), it often is not taken seriously enough and barrels start .....[read full text]

The Zwentendorf Nuclear Power Plant was the first and only commercial nuclear plant in Austria. Construction of the plant was finished but it never entered service because of a referendum held after prolonged protests by activists and residents of Zwentendorf. The result was a narrow majority of 50.5% voting against start-up.

Following the referendum, a law was passed prohibiting the construction and operation of fission reactors for electrical power generation.

The building has since been used for research purposes, training personnel and for filming. In 2009 a Solar Power Plant constructed on the premises of the nuclear power plant went into operation and a research center for photovoltaic systems was established in cooperation with Tec.....
