Rolls-Royce was awarded a contract by China National Nuclear Corporation (CNNC) to provide the Neutron Flux Monitoring System for two nuclear reactors currently under construction in China.
As part of the contract, Rolls-Royce say they will provide a complete system using the Spinline digital technology, including ex-core neutron detectors, cables and connections and associated electronic systems, to Zhangzhou 1 and Zhangzhou 2, both of which use the Hualong One (HPR1000) reactor design.
“The system will be designed, manufactured, tested by Rolls-Royce I&C teams based in Grenoble, France. The on-site installation and commissioning will be performed by CNNC, under the supervision of Rolls-Royce I&C teams. The Neutron Flux Monitoring System is a key system for the safety and availability of nuclear reactors, since it measures the neutron flux of the reactor, and thus continuously and instantly monitors its power, the fluctuations of that power, as well as its axial and radial distribution within the reactor.”
Stéphane Lessi, Rolls-Royce Civil Nuclear France, Business Unit Director, said:
“For more than 25 years, we have been collaborating with CNNC in China. We are delighted to have signed this new contract, which is further proof of the confidence that CNNC places in our I&C technologies and in our people.”
Rolls-Royce say they are a world leader for digital Neutron Flux Monitoring System, with more than 130 systems installed or chosen for nuclear reactors worldwide, including 42 systems in China.
