Construction Begins at Lianyungang Nuclear Power Plant with Production of Eight Main Steam Valve Units

CCI has been awarded a $15million contract to provide eight main steam valve units to serve the first two1000-MWe, Russian-designed type NPP91/WWER at the Lianyungang Nuclear Power Plant (LNPP), to be built in Lianyungang, China, north of Shanghai. The selection was madejointly by the Jiangsu Nuclear Power Corp. (JNPC) and the China Nuclear Energy Industry Corp. (CNEIC).

According to Stuart Carson, CCI’s President, “This substantial order represents thegrowing international recognition of the superiority of our many severe service valve types, each specifically designed for a wide variety of applications in the fossil fuel and nuclear power industries, the oil and gas industry, the pulp and paper industry, and many others.”

Four of the main steam valve units will serve each of the two new 1000-MWe NPP units. Each main steam valve unit is made up of five valves: A nominally 23-inch (580 mm) system-medium operated, globe-type, main-steam-isolation valve; a quick-acting pressure-reducing valve with up-stream isolating valve; and two safety relief valves which operate sequentially.
