MSA will supply valves to Tianwan nuclear power plant in China

Czech valve manufacturer MSA, a member of Rimera group, will provide its production to construction project of the third and the fourth block of the Tianwan nuclear power plant, Jiangsu province.

The specially-designed ball valves will be manufactured from November 2014 to May 2015 for Atomstrojexport. The valve medium is sea water that is pumped in the beginning of the nuclear plant operational process, after chemical processing the water is desalted and turned into fresh water that is used for the cooling of power plant reactors.

Valves in nominal sizes 12" – 50" will be equipped with electric actuators or hand wheels and made of stainless steel suitable for operating in aggressive conditions. In this particular case the sealing seats were made of Teflon instead of stainless steel. This modification guarantees maximum tightness as well as reliability and longer service life.

The first and second block of Tianwan nuclear plant were commissioned in 2005. Commissioning of two new blocks is planned to year 2018.
