Title: Concrete Over Packs in Dry-Cask Storage Containment Units
Author(s): Samuel Johnson
Publication: Web Session
Appears on pages(s):
Abstract:Cementitious materials have widespread use in nuclear waste storage and disposal applications, including waste form stabilization, dry storage structures, and repository applications, and in each application, the use of cement-based materials presents unique challenges. For cement-stabilized wastes and repository applications, the transport of radionuclides through the cementitious materials is of great concern, as certain radionuclides are highly mobile in high-pH pore fluid. For intermediate-term dry storage, thermal, radiation, and environmental loading can influence degradation of the portland cement concrete structures, which in turn impacts safe storage.
This session addresses the measurement and modeling of properties that will improve the understanding and prediction of the long-term structural, hydraulic, and chemical performance of cementitious materials used in nuclear waste disposal.
