Radiation detector malfunction at Unit 2 of Japan's Onagawa Nuclear Power Plant causes hundreds of abnormal reading fluctuations

Tohoku Electric Power Company of Japan announced on August 6 that a detection equipment malfunction occurred at Unit 2 of the Onagawa Nuclear Power Plant, located in Onagawa Town and Ishinomaki City, Miyagi Prefecture. The issue involved detectors used to measure radiation levels in the main steam lines, which transport steam generated by the reactor to the turbine. Among the four detectors, one displayed readings in the central control room that surged and dropped sharply, repeating hundreds of times. Based on publicly available information, Tohoku Electric has classified this incident as a detector malfunction rather than an abnormal release of radioactive materials or a sudden change in reactor operating conditions. The company stated that the situation does not constitute a problem under security regulations, meaning that from...

Basic research cracks an application challenge that has persisted for nearly half a century: quantitative prediction of neutron irradiation swelling via ion irradiation

Whether advanced nuclear energy systems can operate safely over the long term depends on the ability of structural materials to resist neutron irradiation damage. Neutrons create numerous atomic-scale defects in materials, which gradually aggregate into nanoscale cavities, ultimately causing material swelling, dimensional instability, and performance degradation. However, obtaining high-dose neutron irradiation data often requires years or even more than a decade, with high costs and post-irradiation sample radioactivity; in contrast, ion irradiation can simulate years of accumulated damage within days and is therefore widely adopted (approximately 95% of irradiation experimental data in existing literature come from ion irradiation). But the dose rate of ion irradiation is typically 3—4 orders of magnitude higher than that of neutron irradiation, making direct conversion between the two results difficult. Recently, the research team of Wang Chenxu and Wang Yugang from the Institute of Heavy Ion Physics, School of Physics, and the State Key Laboratory of Nuclear Physics and Nuclear Technology at Peking University, in collaboration with researchers from the University of Tennessee and other institutions, established a quantitative relationship between material swelling and irradiation dose and dose rate at fixed temperatures based on cluster dynamics simulations, theoretical derivations, and ion irradiation experiments, achieving prediction of neutron irradiation swelling using rapid ion irradiation and providing a new tool for rapid screening and lifetime evaluation of nuclear materials.

South Korea Advances First Domestic Commercial Production of Lu-177 Using Wolsong Heavy Water Reactors

Korea Hydro & Nuclear Power (KHNP) plans to use the heavy water reactors at the Wolsong Nuclear Power Plant to produce, for the first time domestically, the radioisotope lutetium-177 (Lu-177) for cancer treatment. Currently, South Korea relies entirely on imports for this material, which imposes cost pressures and supply instability on local radiopharmaceutical companies such as Cellbion and FutureChem. Industry experts generally believe that domestic production will help build a diversified supply chain and shorten transportation times. The primary goal of this plan is to achieve commercial production of Lu-177, with pilot production expected in 2028 and full-scale production commencing in 2031. Subsequently, KHNP will expand production to include cobalt...

Final Voyage Completed for Rebar Cage Sea Transport to Hinkley Point C Nuclear Power Station

This summer, the cargo vessel Anfield Peak departed from the Port of Bristol in the UK, heading to Hinkley Point C Nuclear Power Station in Somerset. This marked the vessel's final voyage for the related transport mission. Previously, it had made over 100 round trips between the two locations, delivering factory-prefabricated rebar cages to the nuclear construction site. These rebar cages are large in volume and high in density, serving as critical foundational components in civil engineering construction. Under traditional practices, such rebar cages are typically prefabricated on-site before concrete pouring. The Hinkley Point C project, however, has shifted part of the rebar cage prefabrication process to a factory in Bristol, with the cages then transported by sea to the site for installation...

Kazakh experts call for enhanced radioecological monitoring in border regions

As Central Asian countries accelerate the development of nuclear energy, Kazakh experts have recently proposed that the radioecological monitoring system in border regions should be improved as soon as possible to provide long-term environmental data support for the construction and operation of regional nuclear power projects. Relevant materials indicate that nuclear energy is becoming an important direction in the energy policies of several Central Asian countries. Kazakhstan has decided to build its own nuclear power plant, while neighboring countries such as Uzbekistan are also advancing or preparing similar projects. Growing electricity demand and the need to reduce greenhouse gas emissions are key factors driving the development of nuclear energy in the region. Experts believe that nuclear power development involves not only the construction of advanced units, but also the simultaneous establishment of an effective ecological and radiation safety assurance system. Modern nuclear power plants...
