[Asia Economy Reporter Jeong Hyunjin] Doosan Heavy Industries & Construction announced on the 31st that it has signed a supply contract for seismic automatic shutdown equipment, a key component of nuclear power plant instrumentation and control systems, with CTEC, a measurement and control subsidiary under the Chinese state-owned CGN Group.

Seismic automatic shutdown equipment is one of the components that make up the nuclear power plant instrumentation and control system, which functions as the brain and nervous system of a nuclear power plant. It is a safety device that detects earthquakes during plant operation and automatically controls the reactor to stop its reaction if the seismic intensity exceeds a set threshold.

Doosan Heavy Industries & Construction plans to design, manufacture, and test the seismic automatic shutdown equipment it recently secured and supply it to Units 3 and 4 of the Shidao Bay Nuclear Power Plant, located on the coast of Liaoning Province in northeastern China, by 2024. The company also stated that it is negotiating additional supplies with the client.

Previously, Doosan Heavy Industries & Construction completed the development of seismic automatic shutdown equipment in 2011 and supplied it to all 28 nuclear power plants constructed domestically. Nagi Yong, Vice President of Doosan Heavy Industries & Construction, said, "We will strive to secure additional orders for seismic automatic shutdown equipment in the Chinese nuclear power market."

Doosan Heavy Industries & Construction entered the Chinese nuclear power market in 1997 by securing steam generators and heat exchangers for Units 1 and 2 of Phase 3 at the Qinshan Nuclear Power Plant, a Canadian nuclear power plant model (Candu 6 PHWR). In 2005, it secured the reactor for Unit 3 of Phase 2 at Qinshan Nuclear Power Plant, a Chinese nuclear power plant model, and manufactured steam generators and reactors for Unit 1 of the Sanmen Nuclear Power Plant and Unit 1 of the Haiyang Nuclear Power Plant, both based on the US AP1000 model, delivering them in 2012.
