Lesedi evolved from Intens Engineering, which was founded in the mid-1980s, soon after the commissioning of Koeberg Nuclear Power Station in the Western Cape of South Africa.

Lesedi’s main shareholder is Framatome (previously AREVA and renamed in January 2018). Our international nuclear services business unit focuses on exporting core skills and, thanks to AREVA/ Framatome’s global presence, Lesedi provides services and training worldwide.

Today Lesedi is engaged with some of the most significant projects at Koeberg including plant life extension through the replacement of the Steam Generators, the replacement of the water storage tanks (PTR) as well as other modifications required for Koeberg’s life extension.

This work is supplemented by contracts with a number of foreign nuclear power stations located in England, Brazil, China, France and the USA.
