CCI Dives in at Kuosheng Nuclear Power Station

During the 2003 outage in unit 1 of Taiwan Power Company‘s Kuosheng Nuclear Power Station, CCI Switzerland’s Nuclear Services (NS) division took the plunge and successfully installed five suction strainers for the Emergency Core Cooling Systems (ECCS) . . . under water!

After the NS division developed and qualified special equipment to carry out the installation work while under water, specially trained divers dove in to install the five strainers. This underwater job – a first for CCI – included cutting the old strainers and machining the conical 20” thread for the new strainers.

The result of ten years of development efforts, the strainers installed at the power station were designed and patented by CCI Switzerland. These advanced strainers feature maximum filtration surface area to filter out more debris for exceptional performance and improved capacity. In addition, the large filter area decreases the pressure drop, which protects the filtration system from malfunction.

Constructed with a compact, rigid design, the customized strainers are built to withstand high hydrodynamic loads and maintain seismic integrity. Furthermore, the system underwent full-scale testing to ensure peak performance. From conceptual design to installation and commissioning, CCI’s swims the extra mile to meet its customers’ needs.
