NPP-what is it? On Earth, there are a lot of factories that are harmful to the environment. But the most dangerous of them is NPP-Nuclear power plants NPP-nuclear power plant, where the nuclear energy released in a nuclear reactor is converted into electrical energy but when they explode, they become even more dangerous

Описание слайда:

The accident at the npp in Pennsylvania Before the Chernobyl accident at Three Mile Island was considered the largest in the history of nuclear power. The incident occurred on March 28, 1979 in Pennsylvania. The cooling system did not work, and it caused a partial meltdown of nuclear reactor fuel elements. Fortunately, a complete meltdown was avoided, and the catastrophe did not happen. But in spite of a favorable outcome, the consequences of the accident for the US nuclear industry have been enormous. Melting has led to an increase in the radiation background at the station. Victims among the population was not, but 140 thousand people were forced to flee their homes. Consequences of the accident eliminated in 1993, after 14 years. The accident has forced many Americans to reconsider their opinions about the use of nuclear energy. As a result, the construction of new nuclear power stations has been frozen for 13 years.

Описание слайда:

The complex was built in the Windscale plutonium production, but when the US created the atomic bomb on tritium, a complex of converted for the production of tritium for the needs of the UK. For this, the reactor had to be operated at higher temperatures than those for which it was originally designed. As a result, October 10, 1957 there was a fire. First, the operators do not want to put out the reactor with water because of a bomb threat, but eventually gave up and sank it. A huge number of radiation contaminated water into the environment. In 2007, studies showed that more than two hundred residents of the surrounding areas developed cancer.Nuclear power plant in Windscale stopped and closed. The fire at the Windscale nuclear plant.

Fukushima, Japan In March 2011, Japan Earthquake. As a result, three operating units were stopped by the emergency protection. But after an hour electricity supply was interrupted, presumably because of the tsunami that followed the earthquake. This caused the malfunction of systems of normal and emergency cooling and led to a meltdown of the reactor core at power. At the station there was an explosion, which led to the release of significant amounts of radioactive substances into the atmosphere. To protect residents from huge releases of radioactive substances, all local residents were evacuated within a radius of twenty kilometers.
