Finite Element Analysis Enhancement or B-25 Container Dynamic Compaction

PDF Version Also Available for Download.

Description

The document describes initial structural finite element modeling for dynamic compaction of B-25 containers buried in Engineered Trench number 1 at the U.S. Department of Energy's Savannah River Site (SRS), Aiken, South Carolina. Dynamic compaction is the practice of dropping a heavy weight to compact material that has been placed in the subsurface for disposal. B-25s placed in Engineered Trench number 1 contain low-level radioactive waste. Dynamic compaction of buried B-25s is an option that could mitigate subsidence of the cap that is eventually constructed over an engineered trench disposal site. The objective of numerical modeling of the Engineered trench ... continued below

Description

The document describes initial structural finite element modeling for dynamic compaction of B-25 containers buried in Engineered Trench number 1 at the U.S. Department of Energy's Savannah River Site (SRS), Aiken, South Carolina. Dynamic compaction is the practice of dropping a heavy weight to compact material that has been placed in the subsurface for disposal. B-25s placed in Engineered Trench number 1 contain low-level radioactive waste. Dynamic compaction of buried B-25s is an option that could mitigate subsidence of the cap that is eventually constructed over an engineered trench disposal site. The objective of numerical modeling of the Engineered trench system was to evaluate the response of B-25 Containers to dynamic compaction, eventually incorporating dynamic compaction behavior with various degrees of B-25 corrosion. Understanding the structural behavior of buried B-25s over time is important for anticipating and dealing with subsidence. Subsidence may compromise the long-term integrity of the caps placed over the buried waste to limit downward water and contaminant movement through the material.
