Waste Removal Operations and Tank Closure
Maximum Public, Worker, and Environmental Risks in the year 2007 and beyond:
| Public: Low
| Worker: Medium
| Environment: Low
|
Technical Approach Provided by Project Manager:
Key HLW waste removal and tank/facility closure technologies are:
- Salt dissolution via mechanical agitation (slurry pumps),
- Sludge suspension via mechanical agitation (slurry pumps),
- Remote process sampling,
- Corrosion control of the carbon steel waste tanks,
- Heel removal techniques and specialized equipment, and
- Grout formulation to chemically bind radioactive contaminants
The key technology development needs are:
- More cost effective salt removal methods than slurry pumps such as water jetting, hydraulic mining, modified density gradient, etc.,
- Effective methods to remove tank heels (sludge heel, hardened sludge, zeolite, sand, etc.), and
- Enhanced method for retrieval of waste from annulus spaces.
Post 2006 Project Scope Provided by Project Manager:
Waste Removal - Waste will be removed from the remaining 39 tanks and the tanks water washed by FY25. Process facilities will be de-inventoried and flushed out in a similar manner by FY25.
Waste Removal Demonstrations - There are no waste removal demonstrations scheduled after FY04.
Tank/Facility Closure - The remaining 41 tanks will be closed by FY26. Process facilities will also be closed by FY26.
Area Closures - All geographical areas will be closed by FY26 and ready to transition to Environmental Restoration for characterization, remediation (if needed) and final closure activities.
Project End State Provided by Project Manager:
The project will end in FY26 when all waste removal, tank closure, and facility closure activities are complete. All HLW facilities will be transitioned to Environmental Restoration project SR-ER02.
