South Korea's Taesung advances order for Unit 2 of US TerraPower SMR, pivoting to new track in nuclear power and gas turbine forgings

South Korean open-die forging company Taesung is accelerating its entry into the small modular reactor (SMR) supply chain. Data shows that Taesung secured its first order in June this year for rotating plug components of the primary equipment for Unit 1 of US-based TerraPower's SMR, and is expected to advance follow-up orders for related components of Unit 2 of the same project in September. The rotating plug is installed on the upper section of the reactor to support nuclear fuel replacement and in-vessel equipment maintenance, requiring high material resistance to high temperatures and radiation, as well as large-scale forging capabilities. This order therefore not only carries revenue significance but also demonstrates the company's technical validation value in the high-end nuclear power forging segment. TerraPower, founded by Microsoft founder Bill Gates, is developing...

Radiation detector malfunction at Unit 2 of Japan's Onagawa Nuclear Power Plant causes hundreds of abnormal reading fluctuations

Tohoku Electric Power Company of Japan announced on August 6 that a detection equipment malfunction occurred at Unit 2 of the Onagawa Nuclear Power Plant, located in Onagawa Town and Ishinomaki City, Miyagi Prefecture. The issue involved detectors used to measure radiation levels in the main steam lines, which transport steam generated by the reactor to the turbine. Among the four detectors, one displayed readings in the central control room that surged and dropped sharply, repeating hundreds of times. Based on publicly available information, Tohoku Electric has classified this incident as a detector malfunction rather than an abnormal release of radioactive materials or a sudden change in reactor operating conditions. The company stated that the situation does not constitute a problem under security regulations, meaning that from...

Shimane Nuclear Power Station Unit 2 scheduled inspection completion date moved up to September 16

Chugoku Electric Power Co., Inc. announced on August 5 that the schedule for the 18th periodic utility inspection of Shimane Nuclear Power Station Unit 2 has been revised, with the inspection completion date moved up from September 17, 2026 to September 16, and the power generation resumption date moved up from August 19 to August 18. Shimane Nuclear Power Station Unit 2 is a boiling water reactor unit with a rated electrical output of 820 MW. The unit was shut down on February 9, 2026 and entered its 18th periodic utility inspection. The reason for this adjustment is that, during the reactor start-up preparation work, the procurement of the nitrogen gas source used to fill the reactor containment vessel was completed earlier than planned, allowing the related work to be advanced accordingly...

Water Leak at Pipe Joint of Primary Cooling Pump in Unit 2 of Takahama Nuclear Power Plant; Kansai Electric Confirms No Radioactive Impact

Kansai Electric Power announced on August 3 that a water leak was found at a cooling water pipe joint in Unit 2 of the Takahama Nuclear Power Plant in July. According to Kansai Electric Power, an inspection crew discovered the issue during a check inside the intermediate building on July 11, with a leak volume of approximately 3.4 liters, and repairs were carried out on the 14th. The leak occurred at the pipe connection of the No. 1 cooling water pump during a periodic inspection. The pipe has an outer diameter of 2 centimeters, is secured by threaded fittings, and was sealed with sealing tape. Kansai Electric Power preliminarily determined that the leak may have been caused by tape deterioration due to friction or insufficient wrapping. Currently, Kansai Electric Power re-wrapped the sealing tape on the 14th, and Unit 2 of the Takahama Nuclear Power Plant resumed normal operation on July 16, with no other abnormalities identified to date. It is worth noting that the taped section had undergone a disassembly inspection in 2018, when the plant was in a long-term shutdown state.

Unit 2 of Romania's Cernavoda Nuclear Power Plant can only operate for about 5 more days due to the continuously declining water level of the Danube River

Unit 2 of Romania's Cernavoda Nuclear Power Plant is expected to operate for only about five days due to the declining water level of the Danube River. Romeo Urjan, the plant's director, stated that if the Danube's water level continues to drop at a rate of 2 to 3 centimeters per day, Unit 2 will soon cease operation. Unit 1 has already been shut down due to insufficient water flow. Urjan emphasized that despite this, Unit 2 continues to operate within normal parameters, and nuclear safety is not under any threat. To alleviate the situation, relevant authorities are preparing to deploy four barges to divert more water to the plant, hoping to raise the water level by 7 to 8 centimeters, thereby extending the plant's operating time.

Second Ring of Steel Containment Vessel for Reactor Building of Unit 2 at Xudabao Nuclear Power Plant Successfully Hoisted into Place

At 9:57 on August 4, the second ring of the steel containment vessel (hereinafter referred to as CV Ring 2) for the reactor building of Unit 2 at Xudabao Nuclear Power Plant was successfully hoisted into place. The CV Ring 2 hoisted this time is the third ring segment of the steel containment vessel for Unit 2, with a hoisting weight of nearly 890 tons. During the assembly phase, the installation of multiple discipline items, including annular air ducts, steel structural annular corridors, and U-shaped supports for air turbulence, was completed simultaneously for this module, effectively reducing the risk of cross-operation interference in subsequent internal construction of the nuclear island. This approach fully leveraged the advantages of modular construction and effectively translated the concept of "modularize wherever applicable, prefabricate wherever installable" into tangible engineering outcomes. During the assembly and hoisting of CV Ring 2 for Unit 2, Liaoning Nuclear Power, in collaboration with...

Third fuel debris retrieval test at Fukushima Daiichi Unit 2 postponed due to robotic arm malfunction

The robot used by Tokyo Electric Power Company (TEPCO) for the third experimental fuel debris retrieval at Fukushima Daiichi Nuclear Power Station Unit 2 malfunctioned during an on-site operational test, forcing the cancellation of the plan originally scheduled to start after July 2026 if all went well. The company stated it will reassess the relevant procedures. The malfunction occurred in part of the large robotic arm equipment used to collect fuel debris. During an operational test in the reactor building of Unit 2, TEPCO found an abnormality in one of the motors driving the robotic arm, causing the brake to fail to release and the arm to be unable to extend. The company is currently studying the replacement of the faulty motor. The third experimental retrieval plan was to use a large robotic arm...
