The World Nuclear Association lists ten RBMK reactors that are still operating in Russia (one RBMK was recently decommissioned in Saint Petersburg in 2018). Russia is now the only country with these reactors, which were designed and built by the Soviet Union. Four RBMKs are located in Kursk, a city in western Russia.

The U.S. Environmental Protection Agency began phasing out R22 refrigerant in recent years because it was compounding the depletion of the Earth's ozone layer. Launching in 2010, the production and import of R22 was prohibited and by 2020, R22 will essentially no longer be allowed.

Typical reactor may contain about 100 tonnes of enriched uranium (i.e. about 113 tonnes of uranium dioxide). This fuel is loaded within, for example, 157 fuel assemblies composed of over 45,000 fuel rods. A common fuel assembly contain energy for approximately 4 years of operation at full power.

The reactors are all defueled now (though the fuel is still on site, awaiting dry cask storage), and the plant is being decommissioned by several thousand workers. However, parts of the plant remain operational to this day. The massive elect... Chernobyl Nuclear Power Plant is not in use as a power plant.

The Real Chernobyl, a documentary by Sky, shows what really happened at the site of the nuclear disaster in 1986. Following the interest created by HBO miniseries Chernobyl, documentary-makers have gone to Russia over 30 years after the incident to meet some of the real people involved in dealing with it.

Around 10% of the world's electricity is generated by about 440 nuclear power reactors. About 50 more reactors are under construction, equivalent to approximately 15% of existing capacity. In 2018 nuclear plants supplied 2563 TWh of electricity, up from 2503 TWh in 2017.

The heat released by fission in nuclear reactors must be captured and transferred for use in electricity generation. To this end, reactors use coolants that remove heat from the core where the fuel is processed and carry it to electrical generators. Coolants also serve to maintain manageable pressures within the core.
