The pebble-bed reactor (PBR) is a design for a graphite-moderated, gas-cooled nuclear reactor. It is a type of very-high-temperature reactor (VHTR), one of the six classes of nuclear reactors in the Generation IV initiative.
Westinghouse Electric Company LLC is an American nuclear power company formed in 1999 from the nuclear power division of the original Westinghouse Electric Corporation. It offers nuclear products and services to utilities internationally, including nuclear fuel, service and maintenance, instrumentation, control and design of nuclear power plants. Westinghouse's world headquarters are located in the Pittsburgh suburb of Cranberry Township, Pennsylvania. Brookfield Renewable Partners, a Canadian private equity fund and a subsidiary of Brookfield Asset Management is the majority owner of Westinghouse.
Koeberg Nuclear Power Station is a nuclear power station in South Africa. It is currently the only one on the entire African continent. It is located 30 km north of Cape Town, near Melkbosstrand on the west coast of South Africa. Koeberg is owned and operated by the country's only national electricity supplier, Eskom.
The Pebble Bed Modular Reactor (PBMR) is a particular design of pebble bed reactor developed by South African company PBMR (Pty) Ltd from 1994 until 2009. PBMR facilities include gas turbine and heat transfer labs at the Potchefstroom Campus of North-West University, and at Pelindaba, a high pressure and temperature helium test rig, as well as a prototype fuel fabrication plant. A planned test reactor at Koeberg Nuclear Power Station was not built.
Earthlife Africa is a South African environmental and anti-nuclear organisation founded in August 1988, in Johannesburg. Initially conceived of as a South African version of Greenpeace, the group began by playing a radical, anti-apartheid, activist role. ELA is arguably now more of a reformist lobby or pressure group. Considered by some to be a key voice in the emerging environmental justice movement, Earthlife Africa has been criticised for being too radical, and by others for "working with traditional conservation movements" in furthering the environmental struggle.
Pelindaba is South Africa's main nuclear research centre, run by the South African Nuclear Energy Corporation. It is situated near the Hartbeespoort Dam, approximately 33 km (22 miles) west of Pretoria, on the farm that once belonged to Gustav Preller. During the apartheid era, it was the location where South Africa's atomic bombs were partially developed and constructed.
A high-temperature gas-cooled reactor (HTGR) is a type of gas-cooled nuclear reactor which use uranium fuel and graphite moderation to produce very high reactor core output temperatures. All existing HTGR reactors use helium coolant. The reactor core can be either a "prismatic block" or a "pebble-bed" core. China Huaneng Group currently operates HTR-PM, a 250 MW HTGR power plant in Shandong province, China.
The Koeberg Alert alliance is an anti-nuclear activist organisation which emerged from an earlier pressure group in Cape Town called "Stop Koeberg" in 1983. Both were intended to halt construction of the first nuclear power station in South Africa at Duynefontein, 28 km NNW of Cape Town: the Koeberg Nuclear Power Station.
The South African Nuclear Energy Corporation (Necsa) was established as a public company by the Republic of South Africa Nuclear Energy Act in 1999 and is wholly owned by the State.
SAFARI-1 is a 20 MW light water-cooled, beryllium reflected, pool-type research reactor, initially used for high level nuclear physics research programmes and was commissioned in 1965.
The first significant work in astronomy in South Africa was performed by Nicolas Louis de Lacaille between 1751 and 1753, culminating in the measurement of the arc of the southern meridian and a catalog of almost 10 000 southern stars, later published as Coelum Australe Stelliferum.
Floating nuclear power stations are vessels designed by Rosatom, the Russian state-owned nuclear energy corporation. They are self-contained, low-capacity, floating nuclear power plants. Rosatom plans to mass-produce the stations at shipbuilding facilities and then tow them to ports near locations that require electricity.
The TVEL Fuel Company (TVEL) is a Rosatom owned nuclear fuel cycle company headquartered in Moscow. It has operated since 1996.
China is one of the world's largest producers of nuclear power. The country ranks third in the world both in total nuclear power capacity installed and electricity generated, accounting for around one tenth of global nuclear power generated. As of February 2023, China has 55 plants with 57GW in operation, 22 under construction with 24 GW and more than 70 planned with 88GW. About 5% of electricity in the country is due to nuclear energy. These plants generated 417 TWh of electricity in 2022 This is versus the September 2022 numbers of 53 nuclear reactors, with a total capacity of 55.6 gigawatt (GW). In 2019, nuclear power had contributed 4.9% of the total Chinese electricity production, with 348.1 TWh.

Vaalputs is the only South African radioactive waste-disposal facility, called the Vaalputs Radioactive Waste Disposal Facility, operated by NECSA. The facility is located about 100 km south-east of Springbok, in the Northern Cape. It covers an area of approximately 10,000 hectare, measuring 16,5 km from east to west and 6,5 km from north to south at its narrowest point.
South Africa is the only country in Africa with a commercial nuclear power plant.
NUKEM Technologies GmbH is a nuclear engineering and consulting company managing radioactive waste and spent fuel and decommissioning of nuclear facilities. The company is located in Alzenau, Germany. It was established in 2006 as a subsidiary of Nukem Energy. On 14 December 2009, Nukem Technologies was sold to Russian Atomstroyexport for €23.5 million.

Adrian "Adi" Paterson is a South African scientist and engineer best known for his work on Pebble Bed modular reactor research and development. He was CEO of the Australian Nuclear Science and Technology Organisation (ANSTO) from March 2009 till September 2020.
