Engineered Barriers

An experimental approach is introduced for understanding how the engineered barriers of a deep geological repository system are affected by fault movement. The experiments are conducted using laboratory simulation test equipment. So far, the experiments indicate that the metal overpack is rotated within the bentonite buffer due to its plasticity, but not breached. Numerical analyses are also carried out to supplement the range of the experiments, which is limited by the capability of the test equipment.

Engineered Barriers

The Waste Isolation Pilot Plant (WIPP) is a deep geological repository being developed by the Department of Energy as a research and disposal facility in the bedded salt deposit of New Mexico. WIPP is essentially an underground salt mine at 2150 feet (655 meters) below the surface and operates on multiple barrier mechanism. Engineered barriers provide an additional protective measure to prevent the movement of fluid towards the accessible environment. Four types of engineered barriers are used in the WIPP disposal system. This paper presents an analysis of the effectiveness of the engineered barriers in various repository environments.
