History of nuclear energy

The Greek philosopher Democritus of Abdera was the first in history to give a definition of atom as the smallest constituent of matter, in the V century B.C. The term "atom" is a Greek word that means "not divisible". But later, with the arrival of nuclear fission it's possible to split atoms to…

The atom What is it?

What is an atom? Imagine you have a piece of iron. The parts. You still have two pieces of iron but smaller. The you come from again ... Every time have smaller pieces until you reach a moment that if the seeming from what you would no longer be hiero.

At this point what is left is an atom, an iron atom.

Definition of atom

From a more formal way, we define as the smallest atom in an element can be divided without losing its chemical properties particle.

The origin of the word atom comes from the Greek, meaning indivisible. At the time that these particles were baptized…

Atomic bomb

The operation of an atomic bomb is similar to the operation of a nuclear reactor, wherein the mass of fuel is well above the critical mass. Initially, the fuel is fragmented, and each of the pieces, enough from the others, so it untreated the critical size; Explosion occurs at closer fragments including sharply.

To increase the performance and efficiency of an atomic bomb to be used practically pure fuels; those used so far have been uranium-235 and plutonium-239. Uranium-235 is difficult and expensive to obtain, because it is not possible to chemically separate it from natural uranium…

What is a proton? Definition

What is a proton? Definition

A proton is a subatomic particle with a positive electric charge that lies within the atomic nucleus of atoms. The number of protons in the atomic nucleus is that which determines the atomic number of an element, as indicated in the periodic table of the elements.

The proton has +1 charge (or, alternatively, 1,602 x 10-19 coulombs), exactly the opposite of the charge -1 containing the electron. In mass, however, there is no competition because the mass of the proton is approximately 1,836 times greater than that of an electron.

The proton is classified as a baryon,…

Atomic number definition

The atomic number is the number of elementary positive charges, or protons, that carry the nuclei of all the isotopes of a given element.

At first, the atomic number was the order that was given to an item when ordered in ascending order according to their atomic masses.

In 1913, Johannes H. van den Broek, analyzing all known information, found that the number of elementary charges of the atomic nucleus was equal to the atomic number.…

Isotopes, what are they?

Isotopes, what are they?

Isotopes are atoms whose nuclei have the same number of protons but different numbers of neutrons. Not all atoms of the same element are identical and each of these varieties corresponds to a different isotope.

Each isotope of the same element have the same atomic number (Z) but each has a different mass number (A). The atomic number is the number of protons in the atomic nucleus of the atom. The mass number is the sum of neutrons and protons of the core. This means that different isotopes of the same atom differ from each other only by the number of neutrons.

The items that can…

Definition of neutron

Definition of neutron

A neutron is a subatomic particle contained in the atomic nucleus. It has no net electric charge, unlike the proton that has a positive electric charge. The number of neutrons in the atomic nucleus of an element determines the isotope to which it is a part.

Discovery of the neutron

The first clue to the existence of the neutron occurred in 1930, when Walther Bothe and Becker, H. found that when alpha radiation fell on elements such as lithium and boron, a new form of radiation was emitted.

Initially, this radiation was believed to be a type of gamma radiation, but it was…

Nuclear power in Argentina

Electricity consumption in Argentina has grown strongly since 1990. Per capita consumption was just over 2,000 kWh / year in 2002 and increased to over 2,600 kWh / year in 2007. Gross production of electricity in 2007 was 115 million kWh, 54% from gas, 27% hydro, 9.4% oil, a 2.2% from coal, and 6.3% (7.2 million kWh) of nuclear origin. In 2008, nuclear energy provides more than 6.8 million kWh of electricity - about 6.2% of total electricity generation.

In Argentina, the electricity production is largely privatized, and is regulated by the ENRE (National Regulatory Authority for Electricity).…

Definition of energy

Definition of energy

Ability of a physical system to produce a job.

This definition, although it is the most widespread, can be misleading because of the vagueness of the term "capacity", and therefore, it is better to define the energy as what, when a work occurs, decreases in an amount equal to the work produced. Energy, then, is measured in the same units as labor.

History of the study of energy

The notion of energy appears for the first time from the investigations of Joule and Carnot on the conversion of heat in mechanical work and thanks to the theory of Helmholtz in which it connects…

Atomic nucleus definition

The atomic nucleus is the central part of the atom small, positively charged and which concentrates most of the mass of the atom.

The main subatomic particles from the nuclei of atoms are protons and neutrons, or nucleons (except ordinary hydrogen or protium, which contains only one proton ). The same chemical element is characterized…

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…
