Turkey's Nuclear Regulatory Authority (NDK) Relaxes Certification Requirements for Testing of Short-Cycle Equipment

Turkey's Nuclear Regulatory Authority (NDK) Relaxes Certification Requirements for Testing of Short-Cycle Equipment

Turkey's Nuclear Regulatory Authority (NDK) has recently adjusted testing requirements for equipment related to nuclear facilities, providing flexibility for equipment with a production cycle of less than 15 days. According to the decision published in the Official Gazette, under specific conditions, when such equipment undergoes certain tests, testing laboratories will no longer be required to hold specific accreditation for the corresponding test methods. This adjustment applies to the supply chain under the framework of the Regulation on Authorization of Nuclear Facilities. When the NDK, suppliers, or subcontractors are unable to provide a laboratory accredited for the relevant test methods, the original accreditation prerequisite may be waived for the testing of such equipment. This indicates that the regulatory authority, while ensuring quality control of nuclear facility equipment, has also left operational leeway for the testing process of short-cycle production equipment.

Kazakhstan Enters a New Era of Atomic Energy, with the Institute of Nuclear Physics Viewed as a Key Pillar of the National Nuclear Industry

Kazakhstan Enters a New Era of Atomic Energy, with the Institute of Nuclear Physics Viewed as a Key Pillar of the National Nuclear Industry

Kazakhstan is entering a new stage of nuclear energy development. The construction of a nuclear power plant means not only the addition of a major energy project, but also the need for the country to simultaneously establish a complete nuclear industry system, including research support, personnel training, experimental infrastructure, nuclear and radiation safety systems, and indigenous technological capabilities. The article points out that a nuclear power plant can be built using foreign project designs, but true scientific and technological capability cannot be purchased along with the equipment; it is gradually formed through the long-term operation of nuclear facilities, conducting research, training engineering teams, and passing on experience. Against this backdrop, the Institute of Nuclear Physics of Kazakhstan is regarded as an important pillar of the future nuclear energy industry. The institution...

Polish President Signs Key Nuclear Power Bill, Allowing Early Construction Works to Start Ahead of Schedule

Polish President Signs Key Nuclear Power Bill, Allowing Early Construction Works to Start Ahead of Schedule

Polish President Karol Nawrocki signed an amendment to the Act on the Preparation and Implementation of Nuclear Energy Facilities and Associated Investments on August 14, aiming to accelerate the construction of nuclear power plants in the country. According to information released by the Presidential Chancellery, the core of this legal adjustment is to allow certain preliminary construction and preparation works to proceed before the final construction permit for the entire project is granted, thereby shortening the timeline for large-scale nuclear projects. The amendment concerns Polish laws related to the preparation and implementation of nuclear energy facilities and associated investments. The new regulations introduce a new type of permit, namely the permit for preliminary construction works of nuclear energy facilities. Once this permit is obtained, the investor can carry out some early-stage construction and preparation works before all complete project investment documents have been fully approved.

CGN Dasheng Launches BV Cable X-Ray Thickness Gauge for Full Online Inspection of Cable Insulation Layers

CGN Dasheng Launches BV Cable X-Ray Thickness Gauge for Full Online Inspection of Cable Insulation Layers

CGN Dasheng Accelerator Technology Co., Ltd. recently announced that its BV cable X-ray thickness gauge can be used for online inspection of insulation layers during cable production. The system employs X-ray technology to perform real-time measurement of key parameters such as cable outer diameter, inner diameter, wall thickness, eccentricity, and concentricity, replacing the potential detection blind spots inherent in traditional sampling inspection methods. In cable production, insulation layer thickness directly affects product safety and material utilization. Traditional inspection typically relies on sample cutting, manual measurement, and recording, with limited inspection frequency. If issues such as uneven wall thickness or eccentricity occur during production, they are often difficult to detect in a timely manner, which also hinders subsequent quality traceability and process adjustment. According to the company, the equipment...

Heat Exchangers and Mechanical Filters for Russian Nuclear-Powered Icebreakers Complete Testing

Heat Exchangers and Mechanical Filters for Russian Nuclear-Powered Icebreakers Complete Testing

On August 11, 2026, the manufacturing project for equipment supporting Russian nuclear-powered icebreakers achieved a milestone. InterPolaris has completed testing of multiple key equipment items, including two shell-and-tube heat exchangers and two mechanical filters. The shell-and-tube heat exchangers that completed testing this time are primarily used to heat water containing purification solutions using heating steam. Compared with conventional heat exchange equipment, the operating environment of marine nuclear power platforms is more complex, imposing higher requirements on structural strength, sealing performance, and operational stability. The horizontal heat exchanger is designed to accommodate prolonged vessel inclination conditions, with mounting brackets capable of withstanding loads from different directions and maintaining stable equipment parameters under complex operating conditions.

Study Reveals Three-Dimensional Pore Networks Inside Uranium-Zirconium Metallic Nuclear Fuel

Study Reveals Three-Dimensional Pore Networks Inside Uranium-Zirconium Metallic Nuclear Fuel

Researchers at the Massachusetts Institute of Technology (MIT), in collaboration with Idaho National Laboratory (INL), conducted three-dimensional imaging studies on irradiated uranium-10 zirconium metallic fuel, revealing the internal pore networks within the fuel and their relationship with chemical changes and fuel-cladding interactions. The researchers believe these results will help improve metallic fuel performance models, providing references for extending the operating cycles of certain reactors and for the design of next-generation sodium-cooled fast reactor fuel systems. Uranium-10 zirconium (U-10Zr) is a uranium-zirconium alloy metallic fuel containing 10% zirconium, which has been extensively tested in sodium-cooled fast reactors such as Experimental Breeder Reactor II (EBR-II) and the Fast Flux Test Facility (FFTF). As advanced reactor research and development progresses, this type of metallic fuel has regained attention, but the details of pore formation, swelling, heat transfer, and interactions with cladding materials under reactor irradiation conditions still require further clarification.
