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...

BESIII Experiment First Confirms the Existence of Glueballs

On August 6, Beijing time, the international collaboration of the Beijing Spectrometer III experiment (BESIII) at the Beijing Electron-Positron Collider announced at the International Conference on High Energy Physics (ICHEP 2026) held in Brazil, in the form of a special plenary report: after 15 years of sustained research, the BESIII experiment has established a complete chain of evidence proving the existence of glueballs, unraveling the mystery that has puzzled the academic community for nearly half a century. This discovery not only provides a decisive validation of the theory of quantum chromodynamics, but also demonstrates the existence of a completely new form of matter—matter composed purely of force. Atomic nuclei are composed of protons and neutrons, which in turn are composed of quarks. Gluons mediate the strong interaction between quarks...

Site Handover for Poland's First Commercial Nuclear Power Plant to Bechtel

New progress has been made in the construction of Poland's first commercial nuclear power plant. The Lubiatowo-Kopalino site in the Pomerania region of northern Poland has been handed over to Bechtel of the United States, and earthworks at the project site are underway. Polskie Elektrownie Jądrowe (PEJ), Poland's state-owned project company, stated that Bechtel has replaced PEJ as the site coordinator for the project. Under the Polish government's earlier arrangement, the nuclear power plant will feature three Westinghouse Electric Company AP1000 pressurized water reactor units. In 2023, Westinghouse Electric Company and Bechtel formed a consortium to jointly advance project implementation. The nuclear power plant is sited in the Lubiatowo-Kopalino area along the Baltic Sea coast in Poland.
