Name and Location
Koeberg nuclear power station steam-generator replacement project, Western Cape, South Africa.

Client
Eskom.

Project Description
The current steam generators in Unit 1 and Unit 2 at the Koeberg nuclear power station have been in operation since 1983/4 and 1984/5 respectively; as a result, Eskom plans to replace them.

This will involve the design, manufacture and installation of three steam generators in each of the two operating units, as well as the safety analyses and studies required for the replacement of the six steam generators.

The new generators will incorporate modern design features for easy maintenance and inspections, and improve heat-transfer efficiency, leading to the overall efficiency of the power station.

The installation of the generators will be conducted during the scheduled refuelling, inspections and maintenance outages of the two units at the power station.

Value
Eskom has stated that the outcome of current “commercial process” will determine the total cost of the project.

Duration
Based on the lead times for the manufacture of six new steam generators, Eskom is planning for installation to take place in 2018.

Latest Developments
France's Areva has won a contract to replace six steam generators at South Africa's Koeberg nuclear power plant.

The refit is part of a programme to install up to 9 600 MW of new nuclear power by 2030.

The new generators will be installed in 2018, Eskom has said.

Financial details of the refit have not been disclosed.
