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.

U.S. NRC to Debut Modernized Hearing Process in Advanced Reactor Licensing Review for the First Time

The U.S. Nuclear Regulatory Commission (NRC) will hold a public hearing on August 13 in Oak Ridge, Tennessee, to consider the Tennessee Valley Authority's (TVA) application to build a small modular reactor at the Clinch River site. This will mark the first time the NRC applies its modernized mandatory hearing framework in an advanced reactor licensing review. According to the NRC, the new hearing process is designed to give the public earlier insight into the agency's review of the project's safety and environmental impacts, while improving the transparency, predictability, and efficiency of licensing reviews. As part of its licensing modernization efforts, the NRC currently aims to complete construction permit-related decisions within 18 months. TVA plans to...

Construction of Proton Therapy Center in Ulsan, South Korea Faces Hurdles: Government Funding Allocation Adjustments Impact Project Progress

The proton therapy center construction project in Ulsan, South Korea, has recently encountered obstacles to progress. The project was once regarded as a key component in improving the regional cancer treatment system in southeastern South Korea, but due to shifts in government medical financial support priorities, the difficulty of securing large-scale national funding independently has increased significantly. According to information from Ulsan City on August 6, Ulsan City completed the feasibility study and basic planning services for the proton therapy center construction in March of last year and began seeking national funding. However, the Ministry of Health and Welfare responded that it would be difficult to provide large-scale project funding to Ulsan City alone. Previously, Ulsan City had planned to establish a proton therapy center to build a system enabling cancer patients to undergo surgery...

UK's MAST Upgrade sets plasma pressure record in fifth experimental campaign

The UK Atomic Energy Authority (UKAEA) has completed the fifth experimental campaign of its flagship fusion experiment, MAST Upgrade. The campaign, conducted between 2025 and 2026 at the Culham Campus in Oxfordshire, UK, produced over 1,100 plasma pulses and achieved the device's highest-ever plasma pressure while overcoming plasma instability issues. In fusion devices, hydrogen isotopes must be heated, compressed, and confined under extremely high temperatures and pressures. The higher the plasma density and temperature, the stronger the fusion reaction, and high-pressure plasmas are also closer to the operating conditions required for future commercial fusion power plants. UKAEA stated that this...
