Three-dimensional thermal analysis for a conceptual high-level waste repository in welded tuff

Creators

Description

A near-field, three-dimensional, thermal-conduction analysis was done for 2.16-kW high-level waste canisters emplaced in welded tuff. Initial thermal loadings of 75 and 100 kW/acre were investigated. The conductivities used were 2.4 W/m.0C for the saturated tuff and 1.55 W/m.0C for the dry tuff. The tuff was modeled as always saturated and with boiling of the interstitial water. Calculations were done with the ADINAT finite-element code and associated pre- and post processor codes. For the 100-kW/acre initial loading, boiling of the interstitial water, and an initial temperature of 350C, the maximum canister temperature was 2960C
