Mechanical and cathodic protection aspects of multi-barrier tuff repository canister designs

The main objective of this work is to design a Multi-Barrier container for storing spent fuel. Design analysis included dimensioning the canister and the concrete pedestal utilizing available materials data, stress calculations and corrosion data. The various corrosion modes were identified, and a sacrificial anode was designed to cathodically protect the waste package for a period of 10,000 years. The sacrificial anode is to be made of magnesium. Langelier and Larson's Indices were calculated and speciation calculations of J-13 water was carried out with the help of a program (WQ4F). This program determines the solids that might precipitate and form scales. When the design was completed, aspects of fabrications were examined to see if this design was practical enough and whether fabrication was feasible.
