The nuclear power plant in Obninsk was the first nuclear power plant to be connected to the grid, supplying electricity to residences and businesses on June 26, 1954.
A total of 411 nuclear power reactors operate in 31 countries.
93 nuclear reactors generate energy in the United States, 56 in France, and 55 in the People's Republic of China.
Nuclear power plants supply about 10% of the world's electricity.
The Akkuyu Nuclear Power Plant will generate approximately 35 billion kWh of electricity per year. This means that it can cover all the electricity needs of Istanbul.
Türkiye currently exhibits a 70% dependency on foreign energy, with 98% of natural gas and 92% of petroleum being sourced through imports. The commissioning of nuclear power plants is expected to reduce the dependence on imported energy resources.
There are 5 countries rich in oil and natural gas, constituting 1/3 of the world's oil reserves and half of the natural gas reserves, host more than 1/3 of the world's nuclear power plants.
A total of 58 nuclear power reactors are under construction in 17 countries. Among them, 22 are under construction in the People's Republic of China, 8 in India and 4 in Türkiye.
France meets 63% of its electricity needs through nuclear power plants. Currently, 56 nuclear power reactors are in operation in France and 1 nuclear power reactor is under construction.
Russia meets 20% of its electricity needs through nuclear power plants. Currently, 37 nuclear power reactors are in operation in Russia, and 3 nuclear power reactors are under construction.
China meets 5% of its electricity needs through nuclear power plants. Currently, 55 nuclear power reactors are in operation in China, and 22 nuclear power reactors are under construction.
Nuclear power plants provide 18% of electricity in OECD countries.
European Union countries cover 25% of their electricity needs from nuclear power plants.
The lifespan of nuclear power plants typically ranges from 60 to 80 years, while wind power plants have a maximum lifespan of 25 years, and solar power plants typically operate for 30 years.
Out of 8,760 hours in a year, nuclear power plants operate for an average of 8,000 hours, generating electricity. Hydroelectric power plants operate for 4,000 hours, wind power plants for 3,000 hours, and solar power plants for 2,500 hours.
Nuclear energy can also be utilized in areas such as sea water treatment, hydrogen production, urban heating and various industrial applications.
The Small Modular Reactors are reactors with a power of up to 300 MW. Due to their ability to be installed in smaller areas, they can be used in locations unsuitable for large nuclear power plants.
Passive systems are those that automatically activate in case of an emergency and do not require external intervention; they contribute to keeping the reactor safe. These systems stand out in the new generation and Small Modular Reactor designs.
Nuclear safety is the highest priority principle in the nuclear energy sector, where potential risks are minimized, and measures are taken with the safety of people and the environment in mind.
The nuclear safety culture is the set of values, norms, behaviors and attitudes adopted in nuclear facilities. Its objective is to ensure the highest level of safety for people, the environment and the facility.
The radiation exposure from a single use of a tomography device is 1,100 times the amount received by a person sitting at the door of a nuclear power plant every day for a year
Radiation is a natural phenomenon and an omnipresent component of the environment. Naturally occurring radioactive substances are present in the earth's crust, on the floors and walls of our homes, schools or workplaces as well as in the food and beverages we consume.
The best-known examples of naturally occurring radiation in food are bananas and Brazil nut. They contain potassium and some radium absorbed from the soil.
The air we breathe, as well as our muscles, bones, and tissues, naturally contain radioactive elements.
There are nuclear power plants in close proximity to some of the world's important tourism centers. The Nogent Nuclear Power Plant is 90 km away from Paris, one of the most important tourism centers, and Bradwell Nuclear Power Plant is only 70 km away from London.
All 8 of the world's leading countries in agricultural product exports have nuclear power plants. The Loire River, listed as a World Cultural Heritage site and a hub for agricultural activities, is home to 14 nuclear power plants.
The water vapor emitted from the cooling tower of nuclear power plants is similar to the dense vapor produced when cold water is poured on a hot surface, and it is not radioactive.
Nuclear power plants do not produce direct carbon dioxide emissions. They contribute to the fight against climate change as they do not emit greenhouse gases, during electricity generation.
The nuclear fuel cycle covers the safe and sustainable management, storage, processing, or final disposal of the uranium mineral. This process includes extraction from the mine, processing, loading into the reactor, and the subsequent removal of used fuel from the nuclear reactor.
Used fuels are placed in cooling ponds for at least five years. Subsequently, various methods, including long-term storage in underground facilities, temporary storage in special containers, and underwater storage in pools, are considered as options. Most importantly, it is never released into the environment.
Uranium exists in nature as six isotopes, ranging from U-233 to U-238. U-238 constitutes 99.3% of all uranium, while U-235 makes up approximately 0.7%. To utilize uranium in nuclear reactors, it is necessary to enrich U-235, meaning to increase the proportion of the U-235 isotope in uranium.
The nuclear sector provides employment not only in the field of nuclear power generation, but also in various business areas, such as research and development, engineering, construction and maintenance.
The USA meets 18% of its electricity needs from nuclear power plants. Currently, there are 93 nuclear power plants in operation, and 1 nuclear power plant is under construction.
In 2022, Germany covered 6% of its electricity needs from nuclear power plants, while 31% was covered by coal. Germany put the first nuclear power plant into operation in 1961.
Türkiye Nuclear Energy Co. (TÜNAŞ), in place of EUAS International ICC which was established abroad in 2015, was established as EUAS International A.Ş. in Turkey in 2022 within the framework of Law No. 4646; and then the company title was changed to TÜNAŞ.
