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 the 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
Westinghouse Electric Company has filed an interdict in a Johannesburg High Court to reopen the bidding process for a contract awarded to French rival Areva to replace six steam generators at the nuclear power plant.

However, South Africa's power utility Eskom says the matter is a done deal and Areva has won the contract to provide the generators to the Koeberg nuclear power plant.

The refit is part of a programme to install up to 9 600 MW of new nuclear power by 2030 to help Africa’s most advanced economy ease chronic electricity shortages.

"It will be clear that a continuation of the current process is necessary and a reversal of the announced initial preferred candidate decision is appropriate,” a Westinghouse spokesman has said.

Eskom says it will provide Westinghouse with the documents it is requesting through the courts. "Eskom’s internal approval processes for the replacement of the Koeberg steam generators have been completed," the utility has said in a statement.

Key Contracts and Suppliers
Group Five and Lesedi Nuclear Services (design, manufacture and replacement of refuelling water storage tanks).
