An Advanced Cold Process Canister Design for Nuclear Waste Disposal

  • Heikki Raiko (a1) and Jukka-Pekka Salo (a2)

Abstract

An advanced cold process canister design, ACPC-design, is introduced in this paper. The cold process canister consists of a steel canister as a load bearing element, with an outer corrosion shield of copper, Fig. 1 - Fig. 4. The canister will be rilled with granular material, such as lead shots, glass beads or quartz sand.

The conditions for the canister design are presented: dimensioning against radiation, allowed heat loads, strains, corrosion and leak tightness etc. The mechanical dimensioning of the copper/steel canister is made according to the Finnish standards (SFS) for pressure vessels.
