Technical Approach Provided by Project Manager:
The D&D Project will achieve cleanup goals through decontamination in conjunction with demolition and/or entombment of facilities. The wastes generated through the D&D Project will typically be disposed in the ERDF. Surplus facilities that are currently in the ER program will be characterized in preparation for D&D activities. Hazardous substances will be removed from the facilities and radiological contamination will be removed or fixed prior to demolition activities. Clean structures will be removed to below grade (3ft), collapsed in place, and covered with clean soil for site restoration. Contaminated facilities will be removed and disposed at the Environmental Restoration Disposal Facility (ERDF). Soil contamination sites in close proximity to the surplus facilities, and soil contamination under the facilities, may be remediated during D&D. If the contamination in the soil is extensive the work will transfer to the Remedial Action project. The 100 Area ancillary facilities will be D&D with any wastes being disposed of in the ERDF. The 100 Area reactors are assumed to be placed in interim safe storage with final disposition being one-piece removal and burial in the 200 Area. The interim safe storage is a planning assumption only. Currently a team of regulators, DOE, and contractor staffs are negotiating a path forward for the 100 Area reactors. The majority of 200 Area facilities will be D&D with any waste being disposed of in the ERDF. The exceptions are the 200 Area canyon facilities, which are assumed (for planning purposes only) to be demolished in place and covered by a barrier. The 200 Area Canyon Strategy development is being initiated in FY97. This activity will evaluate alternatives for the D&D of these facilities. The final decision will be through a Record of Decision. The 300 Area facilities will be D&D with any waste being disposed of in the ER Disposal Facility. The technologies used for D&D consist of standard construction demolition techniques (i.e., wrecking ball, shears, excaualer, explosives, etc.) The Hanford Site utilizes the Site Technology Coordination Group to identify technology needs for Hanford projects. Once the needs are identified they are presented to the Technology Management Council, which determines the needs that should be forwarded as funding requests to DOE-HQ EM-50 National Focus Areas. When approved, the technology demonstration is performed as an integrated EM-40 and EM-50 activity. The following technology needs have been identified as high priority for D&D: Cutting technologies for size reduction of radioactive equipment and materials. Improved techniques foe removal of fixed surface contamination. Improved characterization techniques for differentiation of contaminated and non-contaminated materials. Improved techniques for the cleanup of reactor basin water. The interim safe storage of the C Reactor is being utilized as an integrated demonstration of D&D technologies with EM-50.Post 2006 Project Scope Provided by Project Manager:
102 facilities will remain to be D&D in the 100 Areas. Several hundred 200, and 300 Area facilities will remain to be D&D. Included in this group are five canyon facilities and the Plutonium Finishing Plant.Project End State Provided by Project Manager:
The D&D Project will support the goals and endstates for the areas of the Hanford Site that are referenced in the Hanford Site Strategic Plan as the Reactors on the River, the Central Plateau, and the South 600 Area. Reactors on the River Goal: Remove and/or stabilize spent fuel, surplus facilities, and waste sites to protect groundwater and the Columbia River, and ensure protection of people, the environment, and natural/cultural resources. Pending Congressional action on the Wild and Scenic River designation, use will continue to be restricted; sensitive ecological, cultural, and native American resources will be protected. Facilities Endstate ? Reactors placed in interim safe storage for up to 75 years pending future removal. ? Reactor blocks transported to Central Plateau for disposal. ? Removal of non-essential, surplus buildings and facilities that do not have identified post-cleanup uses. Central Plateau Goal: The 200 Areas and Central Plateau will be used for the management of nuclear materials and for the collection and disposal of waste materials that remain onsite and for other related and compatible uses. Cleanup levels and disposal standards will be established that are consistent with these long-term uses. Facilities Endstate ? Dismantle, or close through entombment, D&D facilities currently assigned to the ER program. ? Remove non-essential, surplus buildings and facilities that don't have identified post-cleanup uses. South 600 Area Goal: The 300 Area waste sites, materials and facilities will be remediated to allow industrial and economic diversification opportunities. The federal government will retain ownership of land in and adjacent to the 300 and 400 Areas, but will lease land for private and public uses to support regional industrial and economic development. Excess land within the 1100 area will be targeted for transition to non-federal ownership. Facilities Endstate ? Reuse facilities for economic diversification where feasible. ? Remove non-essential, surplus buildings and facilities that don't have identified post-cleanup uses.The full list of science research awards that have the potential to address projects such as this one, which deals with Decontamination and Decommissioning, Health / Ecology / Risk, and Remedial Action problems, are listed in the Index of Research Awards by Environmental Management Problem Area, in the back of this appendix, under the headings "Decontamination and Decommissioning, Health / Ecology / Risk, and Remedial Action".
