Core Viewpoint - The achievement of 100% localization of spare parts for the Haiyang Nuclear Power Units 1 and 2 marks a significant step towards the self-sufficiency of China's nuclear energy industry, enhancing the high-quality development of the sector [2]. Group 1: Localization Achievements - The Haiyang Nuclear Power project has completed the localization of key components and materials, transitioning from technology introduction to independent innovation over eight years [2]. - The main pump frequency converter, a critical device for the third-generation passive nuclear power units, has been successfully localized, which previously relied heavily on imports [4]. - The localization of the frequency converter has prevented four instances of unplanned shutdowns, demonstrating its technical performance meets international advanced levels [4]. Group 2: Collaborative Innovation - Shandong Nuclear Power has established an integrated collaboration mechanism involving production, education, research, and application, exemplified by the development of the ultrasonic flow meter for main water supply [6]. - The successful development of the nuclear-grade flow meter has overcome numerous technical challenges and is recognized as a domestic innovation with international leadership [6]. - Partnerships with various institutions have led to the design and manufacturing of core components, fostering an open and collaborative innovation ecosystem [6]. Group 3: Systematic Advancement - Over the past eight years, Shandong Nuclear Power has conducted 60 review and appraisal meetings, resulting in the localization of over 100 spare parts projects [8]. - The company has established a positive development path from "single-point breakthroughs" to "systematic verification" and "scale application," significantly reducing the impact of international supply chain fluctuations [9]. - The achievement of 100% localization of spare parts reflects not only technical capabilities but also an overall enhancement of the collaborative and self-controlled capabilities of the industry [9].
