Evaluation of Frost Heave on Waste Transfer Lines with Shallow Depths in DST Farms

摘要

The purpose of this document is to evaluate the effect of frost heave on waste transfer lines with shallow depths in DST farms. Because of the insulation, and well compacted sandy material around waste transfer lines, the type of sandy and gravel soil, and relatively low precipitation at Hanford site, it is concluded that waste transfer lines with one foot of soil covers (sandy cushion material, and insulation) are not expected to undergo frost heave damaging effects.
