我国首个核电站核功率自动标定系统投用

Core Points - The first automatic nuclear power calibration system in the domestic nuclear power industry has been put into operation at Liaoning Hongyanhe Nuclear Power Co., Ltd, significantly reducing calibration time from at least 8 hours to 70 seconds, enhancing response speed by over 400 times [1][2] - The system addresses the common industry issue of measurement accuracy affected by fuel burnup at the end of the fuel cycle, which traditionally relied on manual calculations and adjustments, posing risks of operational errors and power generation losses [1] - The development of the system involved a collaborative team from Liaoning Hongyanhe Nuclear Power Co., Ltd and Suzhou Thermal Engineering Research Institute, overcoming multiple technical challenges over a 20-month period [1] Economic and Safety Benefits - The automatic calibration system is expected to eliminate the risk of human error in operations, providing a more reliable guarantee for the safe and stable operation of the units [2] - It is estimated that each unit can increase power generation by approximately 7.2 million kilowatt-hours during each fuel cycle (about 18 months), enhancing both economic and safety benefits [2]
