CONSTOR –SPENT NUCLEAR FUEL STORAGE AND TRANSPORT CASK SYSTEM

摘要

Previously, GNB of Essen, Germany developed the CASTOR series of ductile cast ironcontainer systems for the storage and shipping of spent nuclear fuel (SNF). TheCASTOR system has been accepted and deployed internationally by GNB. However,GNB recognized that it needed to develop a new SNF container option for EasternEuropean markets where fabrication capabilities and financial resources are morelimiting. Thus, GNB developed the CONSTOR system (steel-concrete-steel sandwichcask) which incorporates the advantages of the CASTOR system, but at an inexpensivecost.The CONSTOR system was developed specifically for storage/transport of SNF fromRussian RBMK reactors, but can be utilized for other Russian type reactor fuel.Advantages of the system include its ease of handling and loading, bolted lid design ashas been proven with the CASTOR as well as heavy shielding capacity and inexpensivefabrication costs. The system meets the regulations of the IAEA for Type B(U) packagesand has been approved for use by GAN, the Russian licensing authority. In addition to itsuse in the Russian reactor market, the CONSTOR has application for SNF at U.S. utilityand DOE sites.
