With construction all but completed at Unit 1 of China's Taishan nuclear power plant 130 kilometers from Hong Kong, the unit having already completed cold functional and thermal functional testing, state-owned China General Nuclear Power Corp (CGN). said it was replacing a large component, the deaerator , that reportedly cracked during one of the tests.
The plant, which was expected to go operational by the end of the year, is being developed in partnership with French utility EDF. This week, CGN said that “replacement was near completion,” of the component that measures 46.6 meters long and 7.6 meters in diameter. The company said this week that there were “partial defects” in the welding of the component that was shipped in three parts and welded together on site.
The deaerator was made by Harbin Boiler, a subsidiary of Harbin Electric, through a contract awarded by a joint-partnership of Alstom and Dongfang Electrtic, the Hong Kong Free Press reported.
