Hungary Plans to Sink Two Barges Near Paks Nuclear Power Plant to Raise Danube Water Level

Hungary Plans to Sink Two Barges Near Paks Nuclear Power Plant to Raise Danube Water Level

Hungarian authorities plan to conduct controlled sinking of two giant barges, each about 80 meters long, in the river section near the Paks Nuclear Power Plant on August 14, aiming to raise the local water level of the Danube and ensure cooling water supply for the nuclear power units. According to European sources, after the two barges are sunk, the water level in the relevant river section is expected to rise by about 20 centimeters. Recently, persistent high temperatures across many parts of Europe have driven the Danube's water level to a low point, putting pressure on water intake and power generation along the river. The Paks Nuclear Power Plant is the only operating nuclear power plant in Hungary. Due to the low water level of the Danube, the plant's power output has dropped to about 25% of its installed capacity. Earlier this week, Hungarian authorities also announced plans to build a riverbed weir on the Danube. Under current expectations, the project could raise the water level in the relevant river section by about 1 meter.

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 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.

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.
