Akkuyu NPP in Türkiye Holds Full-Scale Joint Emergency Exercise: Cross-Departmental Live Drill Tested Ahead of First Unit Commissioning

The Akkuyu NPP, Türkiye's first nuclear power project, constructed by Rosatom, held a large-scale comprehensive emergency and firefighting tactical live exercise on October 12 at the Büyükeceli site in Mersin Province. The exercise aimed to comprehensively test the multi-agency coordinated response capabilities of nuclear power plant operating shift personnel, external technical support organizations, and Turkish local emergency rescue teams under extreme conditions, providing critical pre-commissioning safety justification for Unit 1 of the project as it formally enters the fuel-loading and commercial power generation phase. Rosatom Director General Alexey...

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.

Unit 4 of Slovakia's Mochovce Nuclear Power Plant Reaches First Criticality

Slovenské Elektrárne stated that Unit 4 of the Mochovce Nuclear Power Plant reached first reactor criticality at 22:10 local time on August 6, and achieved minimum controllable power at 22:31. This is a key milestone in the pre-commissioning work of the unit, indicating that the reactor is ready for subsequent testing. First criticality refers to the first time the nuclear fuel in the core achieves a self-sustaining fission chain reaction. Slovenské Elektrárne stated that first criticality and reaching minimum controllable power are important steps in the commissioning process of a nuclear power plant, used to confirm the unit's readiness to enter the next phase of testing...
