China News Service, Changjiang, Hainan, September 30 (Reporter Wang Xiaobin) On September 29, reporters visited the Hainan Nuclear Power Base Emergency Command Center as part of the "Nuclear Safety Culture Media Tour" event.
Hainan Nuclear Power Base currently has 5 nuclear power units, of which 3 are in operation and 2 are under construction.
Hainan Nuclear Power Base is located in Changjiang County in the west of Hainan Island and is the southernmost nuclear power base in China. After the base's emergency command center completes a new round of transformation in July 2025, it will be able to coordinate the emergency response work of all units at the base, with complete decision-making, communications, radiation monitoring, and fire protection systems. It is regarded as the "emergency center" and "security fortress" of the Hainan Nuclear Power Base.
In a corner of the base, the emergency command center sits quietly on weekdays. Only when the emergency response is activated, will it become the nerve center for the operation of the entire base. To ensure the safety of personnel during emergencies, the center's water, electricity, and air systems have been specially designed to maintain a slight positive pressure indoors, and the air "seeps" from the room to the outside, so that external polluted air cannot penetrate through the gaps; the fresh air system is equipped with filters to filter the air entering the building; the diesel generator set and oil storage facilities can maintain continuous power supply for many days, and domestic water tanks meet the basic water needs of emergency personnel; the building has been reinforced against earthquakes, and the ground elevation is much higher than the design baseline flood level of the factory site.
As an emergency command center, its core mission is to maintain control and command capabilities during emergencies. The Hainan Nuclear Power Base Emergency Command Center is connected to various key points in the base, has the ability to take over and control emergency situations, and is equipped with redundant communication means to connect inside and outside the site. The radiation monitoring system collects environmental data in real time and transmits it back to the command center. The emergency auxiliary decision-making system can realize auxiliary judgment of emergency status and prediction and evaluation of accident consequences.
Unlike many domestic nuclear power bases, the Hainan Nuclear Power Base is not a site with a single owner and a single reactor type - multiple owners such as Hainan Nuclear Power and Huaneng Changjiang Nuclear Power operate here, and multiple reactor types coexist. In an emergency situation, how to ensure that the emergency forces of different units act in a unified manner?
During the interview, the reporter learned that all owners of the Hainan Nuclear Power Base coordinated to formulate the "Hainan Changjiang Nuclear Power Base Emergency Integrated Plan", jointly established emergency organizations, shared facilities and equipment such as the emergency command center, and communication system equipment such as radio alarms and video conferencing to support the collaborative linkage of on-site and off-site emergency organizations. In the event of an emergency, the base will unify the emergency status classification, and the emergency organization will have unified command and response.
This mechanism has been tested on the training ground. From September 28 to 29, 2025, a nuclear accident emergency verification exercise at the Changjiang Nuclear Power Base under the super typhoon scenario code-named "Haihe-2025" and a joint on-site and off-site nuclear accident emergency joint exercise before the first loading of units 3, 4 and small reactors were conducted in Haikou, Danzhou and Changjiang. The exercise simulated being affected by a super typhoon. The power supply outside the base was lost at the same time, the reactor of Unit 3 was shut down, and the base entered an emergency state. The exercise focused on evaluating the execution effectiveness of the base's integrated emergency response plan.
