UK-based Rolls-Royce on 6 April signed a contract to modernise control rod system equipment in 14 of China General Nuclear Power Corporation’s (CGN’s) CPR1000 NPP units in China. It is the first contract of its kind for Rolls-Royce in China and was signed with CGN subsidiary, Suzhou Nuclear Power Research Institute (SNPI). The newly formed partnership will also allow the CGN group to achieve cost reduction and efficiency improvements for the operations of its power plants. Liu Xiaowei, China Country Head, Rolls-Royce Nuclear, said: “SNPI is a leading nuclear technology institution in China, dedicated to ensuring safe and efficient operation of power plants. CGN is a much-valued customer of Rolls-Royce. We’re pleased with the trust they place in us and will continue providing the optimal service solutions to support Chinese nuclear plants modernisation.”

Meanwhile, Rolls-Royce has also signed a new agreement with the Hongyanhe NPP in Liaoning province and renewed contracts for long-term services with Daya Bay NPP in Guangdong province and Ningde NPP in Fujian province. Rolls-Royce has been supplying Instrumentation and Control (I&C) systems since 1994 when the Qinshan and Daya Bay plants began operation. The company currently supplies I&C technology to more than 70% of nuclear reactors in operation or under construction in China, as well as emergency diesel generators to almost 40% of Chinese units.

In March 2017, Rolls-Royce announced that it had completed modernisation of neutron instrumentation systems at units 1 and 2 of the Ling Ao NPP in Guangdong province, based on a contract signed in October 2012 - its first I&C modernisation programme in China. The work involved replacing the analogue system it originally supplied in the early 2000s with a new digital system. The safety critical neutron instrumentation system allows monitoring of instantaneous nuclear power, power fluctuations, and radial/axial power distribution in the reactor by measuring the reactor neutron flux.
