This overhaul will carry out a series of planned tasks including reactor core unloading, equipment inspection and repair, and system testing. The overhaul team will strictly follow nuclear safety regulations and technical specifications to conduct comprehensive inspections and maintenance on the unit's key equipment and systems, promptly identify and address potential issues, laying a solid foundation for the safe and stable operation of the unit in the next fuel cycle.
Since being put into commercial operation, Hainan Nuclear Power's Unit 1 has maintained excellent operational performance, providing stable power supply for Hainan's economic and social development. The successful implementation of this ten-year overhaul will further enhance the unit's reliability and safety, laying the groundwork for its subsequent long-term stable operation. During the overhaul period, Hainan Nuclear Power will closely cooperate with all collaborative units to ensure that all work progresses smoothly according to plan.
