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…
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.…
The Fukushima Dai-ichi nuclear accident is a series of incidents, including four separate explosions, that took place at the Naraha nuclear power plant in Fukushima Prefecture, Japan, following the Tōhoku earthquake and tsunami on March 11. 2011. The Fukushima nuclear facility was a nuclear power plant to convert nuclear energy into electrical energy.
The Fukushima nuclear disaster occurred on March 11, 2011. It is the most serious nuclear accident in history after the Chernobyl nuclear accident.
The accident was caused by an 8.9-degree earthquake near the northwest coast of…
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…
The Three Mile Island nuclear power plant is Troba a l'Illa to the Susquehanna river to the county of Dauphin to Pennsylvania, a deu quilometres to the south-east of Harrisburg ALS Estats Units.
On March 28, 1979, collapse 1 collapse to nuclear reactor number 2, which will be destroyed. Three Mile Island is AIXI IUD because it is Troba to three thousand riu avall from Middletown, Pennsylvania. The nuclear plant will be built originally by General Public Utilities Corporation, later on, with the nou nom of GPU Incorporated.
L'accident is going to classify in level 5 of…
The Chalk River Laboratories or Chalk River Labs and formerly Chalk River Nuclear Laboratories are facilities located near the Chalk River population, Ontario (Canada) dedicated to the investigation of nuclear reactions.
The installation was born in 1942 as a result of the collaboration between British and Canadian nuclear researchers. In 1944 the Chalk River Laboratories were inaugurated and in September 1945 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…
At the moment of analyzing the disadvantages of nuclear energy in the first place, it is necessary to consider the different areas in which nuclear energy is used. The main use of nuclear energy is the generation of electricity. Although electricity production is the most controversial nuclear application, nuclear technology is also used in the military, medical or environmental fields, among others.
One of the advantages of nuclear energy is that it reduces the dependence on thermal power plants and, therefore, the consumption of fossil fuels. However,…
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…
The central Three Mile Island is located about 16 km from Harrisburg in the state of Pennsylvania, in the United States. It is a nuclear power plant with two nuclear pressurized water reactors.
The nuclear accident at the Three Mile Island nuclear power plant occurred on March 28, 1979, one year after the commissioning of unit 2. At around 4 am, the water supply circuit was disconnected. steam turbines which caused the cooling circuit of the primary circuit to stop working.
The overheating produced in the reactor core resulted in an increase in the pressure in the primary…
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…
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,…
The Chernoby nuclear accident was the worst accident in the history of nuclear energy. After 30 years, Chernobyl's current situation remains delicate.
The recovery of the nuclear accident zone and the cleaning products has resulted in a large amount of radioactive waste and contaminated equipment. The generated nuclear waste is stored in about 800 different sites inside and outside the 30 km exclusion zone around the Chernobyl nuclear reactor.
These nuclear waste are partially stored in containers or buried in trenches, which can lead to the risk of contamination of…
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…
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.
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…
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,…
