Fire alarms triggered nine times in four weeks at Japan's Fukushima Daiichi Nuclear Power Station

At 21:44 on September 3, a fire alarm was triggered in the water treatment control room building of Japan's Fukushima Daiichi Nuclear Power Station. Tokyo Electric Power Company (TEPCO) stated that no open flames or smoke were found at the scene. After firefighters arrived and conducted inspections, it was confirmed shortly after 22:30 that evening that this was not a fire. TEPCO said it would subsequently inspect the relevant detectors. Including this incident, the Fukushima Daiichi Nuclear Power Station has triggered a total of nine fire alarms in the past four weeks. Previously, on August 8, a fire alarm was triggered in the maintenance building for Units 5 and 6; on August 12, an alarm sounded in the emergency diesel generator room for the high-pressure core spray system of Unit 6; on August 13, an alarm sounded in the main office building; on August 15, an alarm sounded in the southwest stairwell area of the turbine building for Unit 5...

Cause Identified for Automatic Shutdown of Unit 3 at Shin-Kori Nuclear Power Plant in South Korea

The Nuclear Safety and Security Commission (NSSC) of South Korea reported on the 4th that it has completed its investigation into the automatic shutdown of Unit 3 at the Shin-Kori nuclear power plant during commissioning tests on the 11th of last month, and has approved the resumption of commissioning tests for the unit. The investigation confirmed that the direct cause of the incident was an operator error in inputting parameters during the process of restoring reactor power after the tests. According to the investigation findings, at the time of the incident, while setting the parameters for the turbine control valve position limiter, the operator mistakenly entered a value intended to limit the upper opening limit of the valve as a value in the valve closing direction. This limiter is used to prevent a rapid increase in the amount of steam entering the turbine for power generation within a short period. After the parameter error, the unit experienced an interruption in power output at approximately 80% power level, followed by an automatic shutdown.

The Fifth Meeting of 2026 on the Construction of the Nuclear Power Safety and Health Archive System Convened

Recently, the Working Group on the Construction of the Nuclear Power Safety and Health Archive System held its fifth promotion meeting of 2026 and thematic subgroup meetings. Representatives from all member units of the working group and relevant organizations attended the meetings. The meetings discussed the progress of informatization construction, computing resource allocation, data governance and sharing, and R&D of digital and intelligent applications for the nuclear power safety and health archive system. Live demonstrations were conducted on the functional implementation of the health archive information systems on both the regulatory side and across various corporate groups. The achievements in system construction were summarized on a phased basis, existing issues were reviewed, and near-term work tasks were deployed. The meetings noted that the construction of the nuclear power safety and health archive system is an important endeavor in promoting the transformation of nuclear safety management and regulatory mechanisms. At present, data governance has achieved initial results, the data verification mechanism has been effectively implemented, and the development of application scenarios is being steadily advanced, creating conditions for the continued improvement of the system. The meetings required that: first, continue to adhere to a goal-oriented and problem-oriented approach, focus on the fundamental functions of the system, concentrate efforts on further addressing shortcomings in a targeted manner, and steadily advance system construction; second, in light of pilot application results, promptly conduct reviews and summaries, comprehensively identify difficulties, bottlenecks, and weak links, and improve the system's operational effectiveness across the entire process; third, continue to coordinate and advance various tasks including data benchmarking and warehousing, frontline demand research, and scenario development and implementation, making every effort to ensure the high-quality completion of the nuclear power safety and health archive system, thereby contributing to the continuous improvement of the operational safety and construction quality of nuclear power plants in China.
