The South African Department of Environmental Affairs has authorised Eskom's Final Environmental Impact Report (FEIR) for the construction of the Nuclear-1 new pressurised water reactor (PWR) of up to 4,000 MW in Duynefontein (Western Cape, in the neighbourhood of the existing Koeberg nuclear power plant, South Africa). Two alternative sites were considered, namely Bantamsklip (Southern Cape, South Africa), Thyspunt (Eastern Cape, between Oyster Bay and St Francis Bay). Of these, Duynefontein and Thyspunt are recognised in the FEIR as environmentally acceptable - Bantamsklip, while acknowledged as a viable site for a nuclear power plant, was excluded from the report as the least favourable of the three.
Thyspunt is Eskom’s preferred site but the company submitted Nuclear Installation Site Licences (NISL) to the National Nuclear Regulator (NNR) for both sites back in 2016; they are still being considered.
Under the framework of the 2010-2030 Integrated Resource Plan, South Africa aims to build about 9.6 GW of new nuclear capacity (potential Thyspunt nuclear power plant) between 2023 and 2030, at an estimated cost of US$34bn-US$84bn. The country already has a two-unit nuclear power plant (Koeberg), which has a net generating capacity of 1830 MW.
