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 the physical point of view, electrical energy is negative electric 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

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 Plant - What is it?

Nuclear Power Plant - What is it?

A nuclear power plant is a facility for obtaining electrical energy using nuclear energy.

Its operation is similar to that of a thermal power plant or that of a solar thermal plant: from a source of energy thermodynamics is used to obtain heat, with the heat to get steam and with the steam to drive a turbine that will generate electricity.

The difference between the different types of electrical installations is in the energy source: a nuclear power plant uses the heat released in the nuclear fission reactions of certain atoms, in a thermal power station the heat source (thermal…

Nuclear waste

Nuclear waste

One of the main problems in the use of nuclear energy is the management of nuclear waste as it is very dangerous and difficult to eliminate.

What is done with nuclear waste?

Nuclear waste is one of the main problems related to nuclear energy. If these wastes are not treated properly, they are highly hazardous to the population and the environment.

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

Classifying them by their activity we have:

  • High-level nuclear waste, composed of elements of…

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.…

History of nuclear energy

History of nuclear energy

To explain the history of nuclear energy we could distinguish three major stages:

  • Physical and chemical scientific studies of the elements.
  • The development of the nuclear bomb during World War II.
  • Use of nuclear energy in the civil field.

Scientific studies cover this whole period since the first Greek philosophers began to define atoms, until the development of the first nuclear bomb. In this process, different scientists discover the presence of electrons, neutrons and protons and properties that make one atom more radioactive than another.

Operation of a nuclear power plant

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 power 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…
