Orano USA Transport Cask Reaches S. Korea

Orano USA said Wednesday its first TN-LC transport cask had been delivered to a delegation from Korea Hydro & Nuclear Power Co., Ltd. (KHNP).

Oranao USA cask in S. KoreaKHNP, the third-largest nuclear power company in terms of capacity, capacity, operates 24 nuclear plants in South Korea.  The TN-LC final assembly and testing was conducted in Gunsan, South Korea at SeAH Besteel Nuclear Shop, Orano’s regional partner for the development of high-quality casks.

The TN-LC cask is intended for the secure transport of used nuclear fuel between KHNP sites, but will also be used for global transport services under the TN-LC’s international licenses in the United States and other countries. The first use of the cask is planned by the end of 2021 for an international transport between South Korea and Sweden.

The TN-LC transport cask is designed for both wet and dry used fuel loading procedures. The relatively lightweight cask is designed to be in compliance with safety standards for nuclear energy facilities and research reactors around the world.

On June 22, 2021, KHNP received a license for the first TN-LC transport cask from South Korea’s regulatory agency, the Nuclear Safety and Security Commission (NSSC), for the transport of high burn-up used nuclear fuel. “Burn-up” describes how much energy was produced by a used nuclear fuel assembly and “high burn-up” usually applies to assemblies that powered a reactor for a relatively longer period of time. High burn-up fuel has been safely stored and transported worldwide for many years, including more than 15,000 high burn-up assemblies transported by Orano.
