China Nuclear Control successfully developed a million kilowatt nitrogen 16 radiation monitor independently
[ Instrument Network Instrument Development ] Recently, the first domestically produced million kilowatt-level nitrogen 16 radiation monitor successfully completed the trial operation in Jiangsu Nuclear Power. China Nuclear Control successfully developed a million kilowatt-level nitrogen 16 radiation monitor independently, breaking the technical monopoly of foreign nuclear power plant leakage rate radiation monitoring, laying a solid foundation for subsequent market applications.
The one million kilowatt nitrogen 16 radiation monitor belongs to the nuclear power plant Class 1E equipment. By measuring the nitrogen 16 high-energy gamma radiation appearing in the main steam pipe of the second circuit, the leakage condition of the U-tube of the steam generator is indirectly determined; under the thermal shutdown condition, the gamma radiation of other nuclei appearing in the main steam pipe can be measured. Level is the necessary equipment for the operation of pressurized water reactor nuclear power plants.
CNNC is a wholly-owned company of China National Nuclear Corporation. It was reorganized on October 15, 2013 by China Nuclear (Beijing) Nuclear Instrument Factory and former Beijing Nuclear Advanced Control System Engineering Co., Ltd. It is an international nuclear instrument and control system field. The longest product chain, the most complete variety, and the most complete professional nuclear instrument control supplier.
Based on the high standard, high starting point and high level of business philosophy, China Nuclear Control integrates scientific research and production. Its business scope covers the whole process of nuclear engineering digital control system product development, design, system manufacturing, system integration, engineering implementation and after-sales service. Solutions for the manufacture of nuclear and electronic instruments, environmental monitoring instruments, laboratory instruments, stack measurement control instruments, industrial and agricultural isotope applications, nuclear detection instruments, gas ionization detectors, photomultiplier tubes, inorganic organic nuclear detectors, semiconductor detectors, and Business services, products and technology related to the above-mentioned business import and export, agent import and export business.
The trial period lasted for 5 months, and the million kilowatt nitrogen 16 radiation monitor experienced all phases of the nuclear power plant from zero power to full power. No faults, alarms, abnormal conditions occurred during the test run, data measurement was normal, and operation was stable. The performance indicators meet the operational requirements of the nuclear power leakage rate radiation monitoring channel equipment in Jiangsu.
