The Chemistry Control of PHTS at CANDUS in China

  • 1. CNNP Nuclear Power Operations Management Co. Ltd., Jiaxing (China)

Description

Qinshan Phase Ш NPP is the only PHWR NPP in China which installed two CANDU-6 heavy water reactors each with a capacity of 728 MW(e), which were put into commercial service in 2002 and 2003 respectively. In order to promote low operating costs, longevity of component life and minimize environmental releases and occupational exposure, many modifications and optimizations of the primary heat transport system (PHTS) have been done in these more than 16 years. These included optimizing pH control during normal operation and outages changing 5 micron paper filter cartridges to 0.1 micron glass fibre filter cartridges in the PHTS purification circuit and changing the exchange columns type and volume. Until now, no deposit has been found on the fuel bundles. (author)
