Conceptual Site Model - Argonne National Laboratory

WVDP Phase 1 CSAPWMA 6 to house the 275 canisters of vitrified high-level waste currently stored in theMain Plant Process Building. Preliminary designs for the CISF include a concrete padwith approximate dimensions of 150 ft by 200 ft by 3 ft in thickness. This concrete padwill be used to temporarily store horizontal or vertical shielded concrete storage modulescontaining canisters of vitrified HLW. The exact number of storage modules will dependon the number of canisters of vitrified HLW that will be stored in each individual storagemodule.• WMA 7 is approximately 8 acres. WMA 7 contains the Nuclear Regulatory Commission-(NRC-) Licensed Disposal Area (NDA). Removal of a hardstand is the only activityplanned for WMA 7 as part of Phase 1 DP activities, as described in Section 7.8 of thePhase 1 DP.• WMA 8 contains the SDA, which is not within the scope of the WVDP.• WMA 9 is approximately 12 acres. WMA 9 contains the Drum Cell. The Drum Cell andseveral hardstands will be removed from WMA 9 as part of Phase 1 DP activities, asdescribed in Section 7.9 of the Phase 1 DP.• WMA 10 is approximately 30 acres. WMA 10 includes several support facilities andparking lots. Removal of some of the facilities, facility pads, hardstands, and parking lotsis planned for WMA 10 as part of Phase 1 DP activities, as described in Section 7.10 ofthe Phase 1 DP.• WMA 11 includes the Bulk Storage Warehouse and Hydrofracture Test Well Area. Thesefacilities/areas are physically separated from the primary WVDP premises. WMA 11 isnot within the scope of the Phase 1 DP.• WMA 12 includes all other WVDP areas. As indicated in Figure 1, there are two separateportions of the primary WVDP premises that fall within WMA 12, a portion along thenorthern boundary of the WVDP premises, and a larger area in the central/eastern part ofthe WVDP premises. Currently, there are no Phase 1 DP activities planned for eitherportion of WMA 12 within the WVDP premises.Rev. 1 11
