Dismantling

The three objectives of this work are:
- Obtain representative samples of rock and buffer,
- Select instrument components for characterization,
- Document sample and exposed surrounding environment conditions.

The work involves:
- Removal/modification of monitoring/control systems to maintain continuity of remaining in situ-sensors,
- Removal/sampling of surface materials and concrete surrounding the steel liner,
- Obtaining representative samples of borehole sand, backfill, bentonite, liner, and instruments while dismantling,
- Document activities, samples, and setting conditions (photographs, video clips),
- Securing the excavation, borhole vicinity, and remaining instrumentation for continued monitoring, and
- Maintaining a project activity record.

Results are summarized in the final report of the HE project.
