SDDI Heated Canister Test
The Salt Defense Disposal Investigations (SDDI) heater tests included both numerical models and field experiments to investigate a method for the disposal of DOE high-level waste canisters.
The canisters were placed in an open drift at the Waste Isolation Pilot Plant (WIPP) and covered with run-of-mine salt backfill (about 6 feet deep). The canisters emitted heat, acting as a proxy for radiative emissions, where the salt piles were intended to act as a shield preventing the heat from escaping.
Further, it was expected that the self-sealing plasticity of salt will seal fractures, compact the salt backfill, and close the test drift, effectively permenantly sealing in high-level waste products.
Brine Availability Test in Salt (BATS)
The Brine Availability Test in Salt (BATS) is two-phase thermal testing program in bedded salt at the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico.
Phase 1s of the BATS experiment ran from June 2018 to May 2019, and marked the first heated borehole salt experiments conducted underground at WIPP in more than 28 years. This phase used existing boreholes and was used to "shakedown" the process for Phase 1.
Phase 1 of the BATS experiment is currently under development. Bespoke borehole patterns have been drilled and instrumented for electrical resistivity measurements, acoustic emission monitoring, strain gauges, fiber optic cables, temperature monitoring locations, gas composition analysis, gas stable isotope analysis, and injection and sampling locations for both liquid and gas tracers.
