Pelindaba, South Africa's main nuclear research center
Pelindaba is a research center in South Africa located about 33 kilometers west of Pretoria that focuses on nuclear science and energy. The complex was founded in the 1960s and houses research facilities including the SAFARI-1 reactor, along with office buildings and laboratory spaces situated on the grounds of a former farm.
The center was established in the 1950s to develop South Africa's nuclear energy program, and the SAFARI-1 reactor began operation in 1965. Later, during the 1970s and 1980s, the facility was involved in uranium enrichment until the country signed the nuclear non-proliferation treaty in 1991 and ended its nuclear weapons programs.
The name Pelindaba comes from the isiZulu language and means "end of the discussion". This connection to local language and culture reflects the site's deeper roots in South African heritage beyond its scientific purpose.
The main complex is not open to the public, but the Necsa Visitor Centre is located at Gate 1 on the R104 road and can be visited free of charge. The center is open from Tuesday to Saturday and welcomes school groups with advance arrangements to learn about the site's history and work.
The place was named after a Zulu phrase spoken by a farm worker around 1920 when plans to develop the land as a township were abandoned. A uranium enrichment plant on the site was later called "Valindaba", meaning "we do not talk about this", reflecting the secret nature of the program at that time.
