Assessment of the effective surface area of vitrified waste in Supercontainer disposal conditions

Research outputpeer-review

Abstract

This report corresponds to the level 5 topical report, requested as a deliverable in WP6 of research plan RP.W&D.0061 (O/N reference LTBC02-WAS-01), "HLW and MLW glass source term studies: research programme 2009-2014", as part of the framework agreement with O/N reference CCHO-2009-00970000 (SCK•CEN reference CO-90-08-2214-00). It presents a selection of source and expert ranges for the effective cracking factors and the data to support this selection, as input for performance calculations for vitrified waste in the framework of the Safety and Feasibility Case 1 (SFC-1). This topical report presents and evaluates the most suitable literature data for the initial specific surface area of the Belgian reference vitrified waste. Based on this literature review, we propose a range of reference surface areas that can be used in performance assessment. To select the source and expert range, we follow the definitions given by ONDRAF/NIRAS. Ranges are given for the cracking factor, which is the ratio between the total effective surface area and the external surface area of the waste package.
