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

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,…

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…

Accident treatment plant Tokaimura nuclear fuel

The treatment plant is uranium fuel in Tokaimura (Japan), 120km northeast of Tokyo, in Ibaraki Prefecture. Property is currently owned by JCO Company.

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

The installation consists of three auxiliary buildings uranium conversion:

  • One with an annual capacity of 220 tons of uranium per year for low-enriched (about 5%).
  • Another with an annual capacity of 495 tons of uranium per year for low-enriched (less than 5%).
  • Another, who had the accident,…

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…

Scale INES - International Nuclear Event Scale

The INES scale is a tool to quantify the severity of a nuclear and radiological event (either accidents or nuclear incidents).

INES is the acronym for International Nuclear Events Scale.

It is used worldwide to systematically inform the public about the importance of the nuclear and radiological events from the point of view of safety.

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.

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.

Solar energy plant 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,…
