Nuclear Accidents

Nuclear Accidents

In nuclear energy, we refer to nuclear accident to those incidents that emit a certain level of radiation, which could harm public health.

Nuclear accidents are classified as nuclear accidents and incidents depending on the severity´s level. In this classification nuclear accidents and radioactive accidents are included. To understand the difference between these two types of accidents, a nuclear accident could be the failure of a reactor of a nuclear power plant and a radiation accident could be when pouring a radiation source to a river.

Despite the known nuclear…

Chernobyl Nuclear Accident

Chernobyl Nuclear Accident

The nuclear accident in Chernobyl (1986) is by far the most serious nuclear accident in the history of nuclear energy. It was classified as level 7 (severe nuclear accident) of the INES scale, the highest value. Although it is the same level at the Fukushima nuclear accident was classified, the consequences of the Chernobyl accident were still far worse.

The Chernobyl nuclear power plant is located near the town of Prypyat, 18km from the city of Chernobyl.

At the time of the Chernobyl nuclear power plant accident provided 4 reactors in operation and two more were under construction.

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,…

Accident In Tokaimura Nuclear Fuel Treatment Plant

Accident In Tokaimura Nuclear Fuel Treatment Plant

The uranium fuel treatment facility is located in Tokaimura (Japan), 120km northeast of Tokyo, in the Ibaraki Prefecture. It is currently owned by the company JCO.

The nuclear accident of the installation took place on September 30, 1999, in the conversion building of the nuclear plant.

The installation consists of three auxiliary uranium conversion buildings:

  • One with an annual capacity of 220 tons of uranium per year for low enrichment (approximately 5%).
  • Another with…

Chalk River Nuclear Accident

The Chalk River Laboratories Chalk River Labs and formerly called Chalk River Nuclear Laboratories is a facility located near Chalk River, Ontario (Canada) population engaged in the research of nuclear reactions.

The installation was born in 1942 as a result of the collaboration between the British and Canadian nuclear research. In 1944 Chalk River Laboratories were inaugurated in September 1945 and the installation put into operation the first nuclear reactor outside the United States.

The NRX is a research nuclear reactor moderated by heavy water, cooled by…

Advantages And Disadvantages Of Nuclear Energy

Advantages And Disadvantages Of Nuclear Energy

In this section we analyze the advantages and disadvantages of nuclear energy. Nevertheless, most organizations related to nuclear energy are already positioned for or against the use of nuclear energy. 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.

The advantages and disadvantages of nuclear energy have made this alternative energy source one of the most controversial on the market today. Understanding the pros and cons of this energy source can help…

Scale INES - International Nuclear Event Scale

Scale INES - International Nuclear Event Scale

Just as the Richter scale is used to quantify the intensity of an earthquake or the Celsius scale to measure temperature, the INES scale indicates the importance of events derived from a wide range of activities, covering the industrial and medical radiation sources, the exploitation of nuclear energy facilities and transport of radioactive material.

The nuclear events can be classified into the INES scale in seven levels. The events of levels 1-3 are called "incidents", while in the case of levels 4-7 are called "accidents." Each level rise in the scale indicates that the…

Nuclear Accident At Three Mile Island

The nuclear accident at the nuclear power plant at Three Mile Island occurred on March 28, 1979, one year after the commissioning of Unit 2 (TMI-2). The nuclear accident occurred the second reactor of the plant;. Reactor pressurized water

The Three Mile Island is located about 16 km from Harrisburg in the state of Pennsylvania, in the United States.

On the 4am circuit responsible for supplying water to the turbines disconnected which caused him to stop the cooling function of the primary circuit.

Atomic Energy

Atomic Energy

Atomic energy comes from the atom, it is the energy that holds together neutrons and protons of the nuclei of atoms. It is also known how nuclear energy, which comes from the nucleus. The name nuclear energy is used because most of the energy of an atom resides in its nucleus.

Two parts of the atom, the nucleus and the crust are differentiated. In the cortex, an indeterminate number of electrons orbit around the nucleus. The nucleus is composed of an indeterminate number of neutrons and protons. The amount of protons in the nucleus will determine the element that the atom is treated,…

Mayak Nuclear Accident

Mayak Nuclear Accident

Mayak is one of the highest points of the planet with radioactive contamination. It is also conce as Mayak Production Association (Russian: Маяк производственное объединение ). These are the names by which a complex known nuclear facilities between the cities of Kaslo and Kyshtym in laprovincia Chelyabinsk, Russia.

The Mayak nuclear accident is little known because the Soviet authorities tried to hide for 30 years nuclear leaks have been occurring.

History of Mayak nuclear plant

The construction and launch of the atomic bomb on the Japanese…

Faiichi 1 Fukushima nuclear plant, Japan

The Fukushima Daiichi Nuclear Power Plant Fukushima nuclear plant or one (Dai-ichi means "number one" in Japanese) is composed of six nuclear reactor nuclear boiling water (BWR). The plant is located in the city of ÅŒkuma (Fukushima Prefecture, Japan). Uses sea water for cooling.

Located just twelve kilometers from another great power, the Fukushima Daini nuclear plant, Fukushima or II, with four reactors.

Transport Of Radioactive Substances

Transport Of Radioactive Substances

The transport of radioactive substances generated by the different applications of nuclear energy is carried out according to the recommendations established by the International Atomic Energy Agency (IAEA), included in the legislation in force through the European Agreement on the Transport of Dangerous Goods by Road.

The set of measures established has the objective of minimizing the probability of a nuclear accident occurring. In case of a nuclear accident the objective is to mitigate its effects, avoiding the dispersion of radioactive material and its possible assimilation by…

Solar Energy Plant In Chernobyl

Solar Energy Plant In Chernobyl

After years of neglect of the exclusion zone of the Chernobyl nuclear plant, it may be given a new use as the Ukrainian authorities are considering turning it into a huge solar power plant.

The Chernobyl nuclear power plant suffered the worst nuclear accident in history when in 1985 exploded the core of its reactor No. 4. The severity of the accident along with mismanagement after the accident, generated a lot of contaminated area and consequently, abandoned.

Now, 30 years later, it is considering giving a new utility: it is turn the area into a plant of photovoltaic solar energy,…

Differences Between Nuclear Fusion Meltdown

In a nuclear accident and the accident at the Fukushima nuclear plant in Japan, usually speaks often of the risk of core melt.

Do not confuse the meltdown of a nuclear reactor with nuclear fusion.

Nuclear fusion is the process in which two atoms are joined to form one single pass. This releases a lot of energy that could be harnessed to generate electricity. Unfortunately, these reactions can not be controlled well and much less to create nuclear power to produce electricity.

Nuclear plants currently use nuclear fission reactions, which is based precisely on the basis atom…
