CGN partners with Rolls-Royce to develop DCS platform

2018-06-27

China General Nuclear Power Corporation (CGN) signed an agreement with UK-based engine manufacturer Rolls-Royce at the third World Nuclear Exhibition (WNE) in Paris, France on June 26.

The agreement will see CGN cooperate more closely with Rolls-Royce to improve the nuclear-grade distributed control system (DCS) solutions with their own advantages for customers across the globe.

This was the third time CGN has attended the WNE. It promoted its “FirmSys”, China’s first nuclear-grade DCS platform developed by CGN subsidiary China Techenergy Co to players in the nuclear power industry from all over the world.



The signing ceremony of the agreement reached by CGN subsidiary China Techenergy Co (L) and the UK-based engine manufacturer Rolls-Royce is held at the World Nuclear Exhibition in Paris, France on June 26.

In addition, CGN also exhibited its robots, Hualong One (HPR1000) reactor design, plasma-based hazardous waste treatment project and electron beam technology for industrial waste water treatment.



The promotion event on CGN’s FirmSys attracts a great deal of attention from the industry during the WNE.

The “FirmSys”, known as the central nervous system of nuclear power plants, is a nuclear-grade digital I & C platform, critical in safe shutdowns and accident mitigation for reactors. It can be applied in safety-grade I&C systems such as reactor protection systems, engineered safety feature actuation systems, and post-accident monitoring systems.

It fills the gap in this field and makes China the fourth country to own intellectual property rights of DCS after the United States, France and Japan.

Boasting a group of cutting-edge technologies such as safety analysis, self-diagnosis, and nuclear grade communication network design, FirmSys has taken a leading position in the industry.

In order to ensure system security, FirmSys adopts an independently designed operating system and communication network. The research and development teams wrote nearly one million lines of software code independently to set up a multi-layer defense system.

FirmSys can be applied in not only various types of reactors but also areas that have highly reliable security control requirements, such as watercraft, high-speed trains and aerospace applications.

It has been involved in the transformation of the nuclear-grade instrument control system of several domestic units already in service, including the Daya Bay, Qinshan and Ling Ao NPPs and is applied in the nuclear power stations at Yangjiang, Hongyanhe, Tianwan and Fangchenggang as well as at the Shidao Bay high temperature gas cooled reactor.

Unit 5 of Yangjiang NPP in South China’s Guangdong province was connected to the power grid on May 23.

Launched in 2014, the World Nuclear Exhibition is held every two years. This year’s event focused on the civil nuclear power and housed 750 exhibitors from 27 countries in an exhibition area of 25,000 square meters (2.5 hectares).

About 80 activities including round-table conferences and seminars were held during the three-day event, which received more than 20,000 visitors.
