Hydraulic pressure test of containment penetration protection sleeves for Haiyang Nuclear Power Unit 3 in China succeeds on first attempt

Recently, the hydraulic pressure test of the containment penetration protection sleeves for the main steam and main feedwater pipelines of Haiyang Nuclear Power Unit 3 of State Power Investment Corporation (SPIC) Shandong Nuclear Power was completed, with all four sleeves passing the test on the first attempt. The protection sleeves are an important part of the containment pressure boundary and can safeguard the bellows expansion joints under abnormal pipeline conditions. It is understood that this test was relatively difficult. The sleeves had long been embedded in the containment, the original pipelines could not be damaged, and the on-site space was narrow, making it impossible to install the tooling. To address these challenges, the production preparation project team innovatively adopted the process of "removing the original guard plate + welding flanges to build a pressure chamber," and joined forces with the design institute and equipment manufacturer to form a special team, conducting multiple simulation verifications and reviewing...

Ganzhou District of Zhangye, Gansu Deepens Full-Chain Closed-Loop Regulation of Nuclear and Radiation: Focusing on 70 Nuclear Technology Utilization Units, with a 100% Closed-Loop Rate for Hazard Rectification

The Ganzhou Branch of the Zhangye Municipal Ecology and Environment Bureau in Gansu Province has recently comprehensively deepened full-chain regulation of nuclear and radiation safety within its jurisdiction, keeping a close watch on 70 nuclear technology utilization units across the district. Through refined management and source-based prevention and control, it has maintained a 100% closed-loop rate for radiation safety hazard rectification, ensuring that the regional radiation environment quality remains continuously safe and controlled. In regulatory practice, the Ganzhou Branch has implemented a multi-dimensional linkage mechanism of inspection, verification, service, and monitoring: internal and external linkage with checklist-based case closure: focusing on four key dimensions—maintenance and operation of protective facilities, implementation of laws and regulations, emergency response capacity, and data quality of the regulatory system—it urges enterprises to carry out grid-based self-inspections, establishes three lists of "problems, responsibilities, and rectification," and implements ledger-based closure management within deadlines...

3-meter-wide hole found at bottom of Unit 3 reactor pressure vessel at Fukushima Daiichi Nuclear Power Station: molten nuclear fuel burned through the base plate, TEPCO advances evaluation of debris removal project

The latest investigation data released by Tokyo Electric Power Company (TEPCO) shows that an irregular circular hole with a maximum diameter of 3 meters exists at the bottom of the reactor pressure vessel (RPV) of Unit 3 at the Fukushima Daiichi Nuclear Power Station (Fukushima No. 1 NPP). This is the first time since the March 11, 2011 Great East Japan Earthquake triggered a tsunami and caused core meltdown that TEPCO has determined the specific shape and dimensions of the damaged bottom of the pressure vessel among the three reactors that experienced meltdown. The conclusion is based on image data obtained by a technical team in March this year using palm-sized micro-drones to conduct 21 flight surveys inside the containment vessel of Unit 3. Based on the multi-angle...
