Letter from P. R. Simpson (Exelon Generation Company, LLC (EGC)) to NRG, "Request to Dispose of Slightly Contaminated Soil In Accordance With 10 GFR 20.2002," dated March 18, 2014
- 2.
Email from B. Mozafari to M. Mathews, "FW: Draft-Dresden_RAls_20 2002 Request," dated April 20, 2015 In Reference 1, EGG requested to dispose of slightly contaminated soil onsite at Dresden Nuclear Power Station, Units 2 and 3 (DNPS). Specifically, EGG requested permission to spread the current inventory of approximately 6,000 cubic meters (m3) of soil, and approval to conduct future disposal operations onsite within the bounds of a radiological dose assessment, not to exceed a total volume of 20,000 m3. This request was submitted in accordance with 10 GFR 20.2002, "Method for obtaining approval of proposed disposal procedures." During the course of its review of the Reference 1 request, the NRC determined that additional information was required for it to complete an Environmental Evaluation of this request. The additional information is requested in Reference 2. Attachment 1 provides the information requested in Reference 2 in.

ATTACHMENT 1 Response to Request for Additional Information Related to Proposed 10 CFR 20.2002 Disposal Procedure Page 2of16 Figure 1: Aerial View of Proposed Disposal Site with Proposed Disposal Area Footprint Highlighted NRC REQUEST GEN-2: Please clarify how the contaminated soil will be emplaced at the proposed disposal site to include the average and maximum thickness of the contaminated soil that will be managed at the site and the maximum dimensions of the controlled disposal area.
EGC Response:
The proposed disposal area would first be prepared by leveling the area and measuring the initial elevation for reference purposes. The addition of soils to the disposal area would occur in campaigns. For example, the initial campaign would involve transfer of the existing 6,000 cubic meters (m3) of soil. Future campaigns would be associated with future projects that displace soil. Soils would be placed in the disposal area and worked to a final depth of not more than two (2) meters (m) above reference elevation and to overall dimensions of 100 m in length by 100 m in width. Soils would be graded and seeded with native grasses to minimize field drainage out of the proposed disposal area and to minimize erosion. The average thickness will depend on the amount of soil being placed in this location, but will at no time exceed 2 m from the reference elevation.

EGC Response:
Both surface water and groundwater pathways were considered in the selection of the site. The most conservative modeling scenario was utilized for the analysis which assumes the resident farmer utilizes water from both pathways. The proposed disposal area is currently listed as a
ATTACHMENT 1 Response to Request for Additional Information Related to Proposed 10 CFR 20.2002 Disposal Procedure Page 10 of 16 "Radioactive Waste Storage" area in DNPS's Offsite Dose Calculation Manual (ODCM) as shown in Figure 5 below, which is a copy of the DNPS ODCM Figure 1-3. The proposed disposal site was selected based on being within the DNPS Restricted Area.
The resident farmer dose modeling scenario was selected and represents a bounding analysis from a radiological exposure perspective. Any potential migration offsite will only serve to further reduce the concentration of radiological constituents and resulting dose. The proposed disposal area location is in an area that minimizes pathways to surface water and in a groundwater flow path that would not impact any groundwater well uptake.
