Welding of main circulation pipeline completed for Unit 2 of Turkey's Akkuyu NPP

On August 27, welding of the main circulation pipeline was completed for Unit 2 of Turkey's Akkuyu Nuclear Power Plant. The pipeline connects the reactor, steam generators, and main circulation pumps, and is one of the key components forming the primary circuit system of the reactor facility. The welding work lasted 73 days and involved welding 32 pipe joints. Engineering technicians, welders, fitters, pipe cutters, non-destructive testing personnel, heat treatment personnel, and quality inspection personnel participated in the relevant operations. During construction, each process step proceeded according to the established technological workflow, and welded joints had to pass inspection before moving to the next stage. According to reports, all welded joints underwent high-temperature heat treatment to relieve internal stress in the metal and ensure compliance with design performance requirements.

Hungary's Paks Nuclear Power Plant Resumes Full-Capacity Operation

Hungary's Paks Nuclear Power Plant has resumed full-capacity operation. Hungarian authorities announced that the plant, which had previously reduced output due to falling water levels in the Danube River, now has all four reactor units and eight turbines operating normally, with electricity generation restored to maximum levels. Located on the banks of the Danube approximately 100 kilometers south of Budapest, the Paks Nuclear Power Plant is Hungary's only nuclear power station. Previously affected by low water levels in the Danube, the plant's water intake conditions for system cooling were constrained, and three units were temporarily impacted with reduced power output. To improve water intake conditions, dike construction was initiated on the riverbed near the plant, with Hungarian experts using thousands of tons of rock and gravel to advance the work, which was completed ahead of schedule.

First unit of Türkiye's Akkuyu Nuclear Power Plant expected to generate power within months

Turkish Energy Minister Alparslan Bayraktar stated on August 13 at the Bosphorus Diplomatic Forum held in Istanbul that the first reactor at Türkiye's Akkuyu Nuclear Power Plant is expected to begin generating electricity within the coming months. Bayraktar said that four reactors are currently being constructed simultaneously at the Akkuyu Nuclear Power Plant, and Türkiye hopes to achieve power generation from the plant's first unit in the coming months. He noted that developing nuclear power has been a long-term goal for Türkiye, and the Akkuyu project will bring Türkiye into the ranks of countries utilizing nuclear energy. Previously, Bayraktar had stated that Türkiye plans to launch the first power unit of the Akkuyu Nuclear Power Plant by the end of this year...

Russia's Atommash Commissions Ultrasonic Weld Inspection Robot to Boost NPP Equipment Testing Efficiency

Atommash, a plant under the mechanical engineering division of Russia's State Atomic Energy Corporation (Rosatom), has recently commissioned a new ultrasonic inspection robot for welded joints, used for weld quality checks on large nuclear power equipment such as nuclear reactors and steam generators. The plant is located in Rostov Oblast, Russia. The new equipment employs two scanning modes and can identify weld defect types and locate defect coordinates. Compared with traditional inspection methods involving manual probe movement, the robot can automatically perform scanning on components with complex geometries, increasing inspection speed by approximately 30% while reducing the need for manual work in hard-to-reach areas. At present, Atommash already operates...

Vacuum test of the turbine condenser at Unit 1 of Akkuyu NPP successfully completed

The vacuum test of the turbine condenser at Unit 1 of Turkey's Akkuyu NPP, built by Rosatom, has been completed. The operation confirmed that the main systems of the turbine unit are ready for the next stage of commissioning. During the test, technicians established the required negative pressure in the condenser, checked the tightness of the vacuum system and the thermomechanical condition of the turbine, while monitoring parameters such as condenser vacuum, steam pressure, bearing temperatures, and thermal expansion of the casing and rotor. During the turning gear rotation of the turbine, the proper operation of the flow path (blades) was confirmed. Systems involved in the operation included: start-up boiler house boilers, vacuum system, bearing lubrication system, hydraulic jacking oil system, main turning gear, steam supply and extraction systems, as well as the equipment thermomechanical condition monitoring system.

Türkiye plans to commission subsequent Akkuyu nuclear power plant units at one-year intervals

Turkish Energy Minister Alparslan Bayraktar said on August 6 that Türkiye plans to commission subsequent units of the Akkuyu Nuclear Power Plant (NPP) at one-year intervals after the first unit goes into operation. Bayraktar stated that Unit 1 of the Akkuyu NPP is scheduled to begin generating electricity by the end of the year, with work on the first reactor's commissioning currently progressing at full speed. According to Türkiye's plan, after Unit 1 enters service, the remaining units will successively enter the commissioning phase.

Czech Republic Leads EU Project to Assess Application of Commercial-Grade Items in VVER Nuclear Power Plants

The Czech State Office for Nuclear Safety (SÚJB) has launched a two-year EU project focused on assessment methodologies for the application of high-quality commercial-grade items in nuclear power plants equipped with VVER reactors. The project aims to establish a unified, expert-judgment-based evaluation process that provides methodological support for nuclear facilities when introducing relevant items, while ensuring that nuclear safety requirements are not compromised. As the nuclear power supply chain landscape evolves, certain plant-specific components may face the need to be replaced by commercial-grade products. In response, regulatory authorities need to establish clear rules to review the suitability, quality assurance, and safety implications of substitute items. The project will focus on evaluating...
