Maximum Public, Worker, and Environmental Risks in the year 2007 and beyond:
| Public: Medium | Worker: High | Environment: Urgent |
Technical Approach Provided by Project Manager:
The key technologies used in the safe storage and management of this liquid high level radioactive waste are: - Evaporation (necessary for volume reduction of waste to manage current available tank space) - Chemical Additions (required to control the pH of the waste being stored to minimize that corrosion of these underground carbon steel waste tanks) - Ventilation (to remove hydrogen gas from tank vapor space) - Cooling (to remove radioactive decay heat from waste tanks) - Transfer Systems (pumping, piping, and jets)Post 2006 Project Scope Provided by Project Manager:
- Waste will be removed from the remaining 11 underground high level radioactive waste storage tanks. These remaining tanks will be closed by the end of FY25 (i.e., services and connecting piping cut and capped, tanks filled with grout). NOTE: Tank closure is covered by Waste Removal Operations and Tank Closure, Project SR-HL03. - By FY16 a second group of tanks (tanks 1, 2, 3, 4, 5, 6, 7, and 8) with common systems plus a Control Room and related waste transfer systems will be closed. Beginning in FY15 a mortgage reduction will be put in place by reducing the Surveillance & Maintenance cost by $20.0 million. - The evaporator systems will have achieved 13.5 million gallons of space gain. - The waste volume being stored will have been reduced from 13.3 million gallons in FY07 to zero gallons.Project End State Provided by Project Manager:
The project will end in FY21 when all waste removal activities are complete and all remaining tanks and facilities have been prepared for closure. This includes de-inventorying the existing underground high level radioactive waste storage tanks and associated facilities. Closure of remaining tanks and facilities is covered by Waste Removal Operations and Tank Closure, Project SR-HL03.The full list of science research awards that have the potential to address projects such as this one, which deals with High Level Waste and Health / Ecology / Risk problems, are listed in the Index of Research Awards by Environmental Management Problem Area, in the back of this appendix, under the headings "High Level Waste and Health / Ecology / Risk".
