Long-term radiation environment at Kola NPP remains under control: gamma dose rates within natural background levels, 15 permanent observation stations operating since 1972

Long-term monitoring results from the external radiation monitoring group at Russia's Kola Nuclear Power Plant show that gamma radiation dose rates around the plant site have consistently remained within natural background radiation levels, with radionuclide concentrations matching background values, indicating a sound radiation environment with no differences from surrounding areas. The station's radiation safety department collects surface water samples from the discharge canal monthly, with monitoring coverage encompassing all elements including the atmosphere, snow cover, bottom sediments, food products, algae, berries, mushrooms, and caged fish. The monitoring architecture consists of two tiers: 15 permanent environmental observation stations have been in continuous operation since before the commissioning of the first reactor unit in 1972; 13 ASKRO automated radiation environment monitoring system stations provide real-time ground-level gamma dose rate data, which is transmitted directly to the Rosenergoatom crisis center and integrated into the national unified radiation monitoring network. Approximately 200,000 cubic meters of air are drawn weekly through air filtration units to capture radionuclides, with volumetric activity of radioactive iodine also measured. A mobile radiological laboratory performs on-site spectrometric analysis. Annually, about 1,200 environmental samples are collected from around the plant site and delivered to the Polyarnye Zori laboratory, where well water samples analyzed by Canberra spectrometers yield "zero nuclide" results, with samples retained for one year for potential re-analysis. Biological samples are processed using the ashing method, and instrument sensitivity is sometimes insufficient to even detect any signal from the plant's impact.

ITER Tokamak Advances Assembly in France, Fusion Experiment Targets 150 Million Degree Celsius Plasma

The ITER tokamak being assembled in southern France is one of the most closely watched large-scale experimental devices in global nuclear fusion research. The machine weighs approximately 23,000 tonnes in total and adopts a donut-shaped toroidal structure, using strong magnetic fields to confine high-temperature plasma, with the goal of replicating on Earth the conditions for fusion reactions that occur inside stars. Its plasma volume is approximately 830 cubic meters, far exceeding previous tokamak devices, and it is therefore expected to validate the key physics and engineering technologies required for future commercial fusion reactors. ITER adopts the toroidal tokamak structure because charged particles can move along toroidal paths under strong magnetic fields, thereby minimizing direct contact with the device's inner walls...

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.

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.

Radioactivity Levels in Arctic Archipelagos Within Background Range, Russian Research Team Reports No Anomalies

On August 13, Andrei Puchkov, senior researcher at the Environmental Radioactivity Laboratory of the N.P. Laverov Federal Arctic Integrated Research Center, Ural Branch of the Russian Academy of Sciences, stated that measurements taken during the 2026 Arctic Floating University expedition's landings on Novaya Zemlya and Franz Josef Land showed very low radioactivity levels, with no anomalies detected. Puchkov noted that the expedition measured radon concentrations at all landing sites, with radon flux densities ranging from below 1 millibecquerel per square meter per second to 200 millibecquerels per square meter per second, all recorded values remaining within background levels. He indicated that permafrost acts as a barrier and shield in the region, preventing radioactive gases from reaching the surface; relatively higher radon fluxes in some areas may be associated with geological features such as fault zones and fracture zones.
