Disposal Concepts for Radioactive Waste in Clay or Till Deposits

Abstract

Two generic schemes for disposal of low and intermediate level radioactive wastes at shallow to intermediate depths in clay/till geomedia are discussed in this paper. Engineered trenches, tunnels and augered boreholes are the technical concepts used in these schemes. Both schemes are constructable at direct construction costs of 377-392 dollars/m^3 for low level and up to 1734 dollars/m^3 for intermediate level wastes, using well proven construction methods and technologies.
