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...
