Nuclear Moratorium

The nuclear moratorium supposed blocking 5 projects of nuclear power plants that had approved the 7 (and some insiders) in Spain.

The National Energy Plans and Nuclear Moratorium

In 1983 he drafted a National Energy Plan in qual nuclear energy in Spain was hit hard.

To bring national electricity production to energy demand and adjust prices of the Congreos Diputoado in June 1984 approved the 1983 National Energy Plan (PEN-83).

The nuclear stop was the main novelty of the PEN-83 that was slowing building program of nuclear power.

Electric power. What is it?

Electric power. What is it?

We define electrical energy as the form of energy that results from the existence of a potential difference between two points. When these two points are brought into contact by an electric conductor we obtain an electric current.

Physical aspects of electrical energy

From a physical point of view, electrical energy is negative electrical charges (electrons) that move through the electric conductor, usually metallic, due to the potential difference between its ends. The reason metal conductors are usually used is because they have more free electrons.

Electric charges moving…

Fukushima nuclear accident

Fukushima nuclear accident

On March 11, 2011 in Fukushima occurred one of the worst nuclear accidents in history after the Chernobyl nuclear accident.

A 8.9 magnitude earthquake off the northwest coast of Japan and a subsequent tsunami severely affected Dahiichi Fukushima nuclear plant on the northeast coast of Japan.

At the time of the nuclear accident at the Fukushima reactors had 6. Reactors 1, 2 and 3 were operating while nuclear reactors 4, 5 and 6 were unemployed for maintenance.

After the earthquake Fukushima reactors that were still running is automatically stopped. To cool the reactors,…

Nuclear energy and the environment

Populritat Although nuclear energy is very low there are applications of nuclear energy for works for the environment.

What is the relationship between nuclear energy and the environment?

To reduce pollution in the environment, we need to know where and how much to find these pollutants, the causes of contaminacióny the right solution to prevent it from spreading.

The main source of pollution is found in human activities contributing largely to the increase in pollutants, growth poblacióny industrial technological developments.

At present, the biggest…

Nuclear power in India

Nuclear power in India

Nuclear power in India is currently in a state of growth with strong nuclear development plans. By 2020, India has set a target to supply 14,600 MW to the grid through the use of nuclear energy. Subsequently, in 2050, India wants 25% of electricity is produced by nuclear energy.

India is a founding member of the global nuclear watchdog, the International Atomic Energy Agency in Vienna.

Because of these restrictions on trade and the lack of indigenous uranium, only India has been developing a nuclear fuel cycle to exploit its reserves of thorium.

Plans to boost nuclear power…

Types of nuclear reactors

We distinguish two types of nuclear reactors

  • Nuclear research reactors. This type of reactors used neutrons generated during nuclear fission reactions to produce radioisotopes that are going to be used in other applications of nuclear energy or materials for studies.
  • Nuclear power reactors. These reactors are based on the use of the thermal energy generated in the fission reactions. The main and most known application of this type of reactor is to generate electricity in nuclear power plants. However, also they are used for desalination…

Nuclear reactor

Nuclear reactor

A nuclear reactor is an installation capable of initiating, controlling and maintaining nuclear reactions (usually nuclear fission) chain that occur in the core of this facility.

The composition of the nuclear reactor is formed by the nuclear fuel, coolant, control elements, structural materials and, in the case in question a thermal nuclear reactor, the moderator.

Nuclear reactors can be classified as thermal reactors and fast reactors.

Thermal reactors are those which function by delaying (moderating) the fastest neutrons or increasing the proportion of fissile atoms.…

operation of a nuclear power plant

Nowadays, the main use given to nuclear energy is the generation of electric power. Nuclear power plants are responsible of doing this process. Almost all nuclear power plants in production are using nuclear fission since the nuclear fusion, despite being under development, is currently unfeasible.

The operation of a nuclear plant is identical to the operation of a thermoelectric power plant operating with coal, oil or gas, except in the way of providing heat to the water for converting this one into steam. In nuclear reactors this process of producing heat is made by the fission reactions…

Advantages and disadvantages of nuclear power

In this section we analyze the advantages and disadvantages of nuclear power. Nevertheless, most organizations related to nuclear energy are already positioned for or against the use of nuclear power. On this site we try to make an objective analysis about this question, giving all the relevant information and offering a space for different conclusions.

Advantages of nuclear power

The generation of electricity through nuclear energy reduces the amount of energy generated from fossil fuels (coal and oil). Less use of fossil fuels means lowering…

Nuclear waste

One of the main problems of the use of nuclear energy is the management of nuclear waste as they are very dangerous and difficult to remove.

What is done with the nuclear waste?

Nuclear waste is one of the main problems of nuclear energy. If this waste is not properly treated, are highly hazardous to the environment poblacióny.

Radioactive waste can be classified according to their physical and chemical characteristics and activity.

Classificandolos for activity are:

  • high-level nuclear waste, composed of fuel elements won.
  • intermediate…

Nuclear power in France

In 1974 the French government decided to rapidly expand production capacity of nuclear power in France just after the first oil crisis. This Decision n was made in the context of a France with substantial competition in engineering, but few indigenous energy resources. Nuclear power, with the cost of fuel is a relatively small the total cost, in this sense, getting a reduction in imports and greater energy security could.

As a result of the decision of 1974, France currently has a high level of energy independence and almost the lowest cost electricity in Europe. It also has a level…
