Koeberg Nuclear Power Station

PRDW have been involved in the site data collection, feasibility studies, licensing reports, in addition to the detailed design of the breakwaters, pump house structures and the cooling water outfall. Work included physical model and mathematical model studies.

The involvement presently continues with ongoing monitoring and operational advice. The cooling water intake basin is designed to function as a stilling basin in which sediment is deposited, enabling sediment free water to be abstracted for power station cooling.

The basin requires maintenance dredging from time to time. A study of the long term strategy and the possibility of a permanent sand pumping facility, with significant long term cost savings for the power station, was undertaken. Jet pump dredging equipment was designed to carry out minor dredging work in house to increase the period between maintenance dredging campaigns.

Work has also been undertaken to develop a system to prevent jelly fish from fouling the intakes.
