en.Wedoany.com Reported - The North China Regional Office of Nuclear and Radiation Safety Supervision (hereinafter referred to as the North China Regional Office) recently conducted supervision and inspection on the design and manufacturing activities of the domestically produced Class 1E electronic governor for emergency diesel generator sets in the first phase expansion project of the Shidaowan Nuclear Power Plant.
The inspection team went deep into the assembly, commissioning, and testing sites, focusing on reviewing equipment nuclear-grade qualification, manufacturing process compliance, and software V&V, to ensure that equipment quality meets the requirements of nuclear safety regulations and standards. In response to discrepancies between the qualification tests of domestically produced equipment and standard requirements, the North China Regional Office adhered to a problem-oriented approach, tightened the quality responsibilities of the general project contractor, system integrator, and equipment sub-supplier, and promoted the advancement of self-developed products from "usable and controllable" to "reliable and stable."
The electronic governor is a core control component of emergency diesel generator sets, and its performance directly determines the response speed and operational reliability of the sets. In the next step, the North China Regional Office will continue to focus on its primary responsibility of nuclear safety supervision, adhere to the principle of combining supervision with service, closely monitor the localization of core equipment and components, and carry out supervision, inspection, and technical support with higher standards and stricter requirements, to safeguard the high-level technological self-reliance and self-improvement of China's nuclear power equipment.
