Hungary's Paks II Nuclear Project May Require Major Adjustments

According to sources familiar with Hungary's nuclear industry and discussions on the Paks II nuclear project, the new Hungarian government led by Peter Magyar believes that the Paks II project, based on Russia's Rosatom design, can only proceed if major adjustments are made. Sources said that due to factors such as ethics, technology, sanctions restrictions, licensing procedures, and existing contract terms, the Paks II project is difficult to continue under its original arrangement. However, industry insiders also believe that it would not be appropriate to abandon the project outright due to short-term sentiment or temporary setbacks. If more participants could be brought in,...

Non-compliant Welding Procedures at Two Units of South Korea's Hanbit Nuclear Power Plant

The Hanbit Nuclear Power Plant headquarters of Korea Hydro & Nuclear Power Co., Ltd. (KHNP) recently confirmed that Units 1 and 2 of the plant had used welding procedure specifications (WPS) that had not undergone impact testing during maintenance of the component cooling water heat exchangers. A retrospective inspection found that among 14 repair activities conducted since the relevant heat exchangers were replaced in 2007, 6 cases involved similar non-compliance. The issue was identified during the 28th planned preventive maintenance outage of Hanbit Unit 1. Inspections revealed that some welding procedure specifications used for repairs to the water chambers of the component cooling water heat exchangers did not meet requirements, involving repair work on worn areas inside the heat exchanger water chambers in the cooling systems of Units 1 and 2.

Radiation Emergency Drill Conducted at Unit 6 of South Korea's Hanul Nuclear Power Plant

Korea Hydro & Nuclear Power (KHNP) recently conducted a comprehensive radiation disaster prevention drill at Unit 6 of its Hanul Nuclear Power Plant to test the emergency response system and on-site handling capabilities under radiation emergency conditions. According to the Hanul Nuclear Power Plant, the drill was held on September 3, organized in accordance with the evaluation guidelines established by the Korea Institute of Nuclear Safety (KINS) and based on the National Radiation Emergency Plan. The drill scenario was not disclosed in advance, and the evaluation methods were also adjusted, with a focus on verifying the unit's response capabilities under actual emergency scenarios. During the drill, all emergency personnel of Unit 6 at Hanul Nuclear Power Plant participated in the response. The scenario simulated a casualty incident occurring within the controlled area, with medical rescue operations organized, and a 3.2 MW mobile generator was used to inspect the operational capability of emergency facilities.

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.
