FC-20-006 Revision 0 FCS Bldg End State Concrete Surface Areas & Volumes Page 4 of 52 1.0 ISSUE STATEMENT The primary purpose of this paper is to provide bounding and conservative estimates of the concrete surface areas, volumes and void spaces in the Fort Calhoun Station Building basements that will remain as part of the end state during License Termination. The Fort Calhoun License Termination Plan (LTP) states that structures will be removed to 3 feet below grade. These estimates are for the basements of the structures that are greater than 3 feet below grade.
2.0 BACKGROUND
STATEMENT The Fort Calhoun LTP states that structures will be removed to 3 feet below grade. Grade level is the 1004 foot elevation at the site. Therefore, basement structures below the 1001 foot elevation will remain as part of the end state and will require characterization and survey in order to meet the 10 CFR 20 Subpart E release criteria. T he impacted end state structures below grade consist of the Turbine Building, Containment, Auxiliary Building, Intake Structure, and Circ Water Tunnels.
3.0 METHODOLOGY This calculation report was prepared in accordance with procedure RP-1010 Rev. 0. Each structure was analyzed for concrete surface area, void space, and concrete volume. The values for simple shapes were determined with an Excel spreadsheet as presented within this paper.
More complex shapes were modeled in AutoCAD, from which data was incorporated into the same spreadsheets to determine the totals for each structure. In order to be bounding and conservative, the concrete volume of piers and other deep foundations are not included. This would further dilute the remaining source term and resulting concentrations for alternate scenarios evaluated. Any rounding or estimating was performed in a conservative manner to assume more surface area, void space, or concrete volume rather than less.
4.0 ASSUMPTIONS The surface areas of the tops of the walls at the 1001 elevation have not been included in the surface area calculations. In addition, only the exposed interior surface areas are calculated.
The exterior surface areas surrounded by soil, including the tops of the walls, are not likely to be contaminated. Therefore, only interior surface areas are calculated in this document. Any further assumptions unique to a structure are included in the corresponding section of the calculation. This report and all assumptions are to be reviewed before, during, and after decommissioning to ensure it reflects the actual end state of the project.

The top of the spent fuel pit foundation is at EL 995-6. It is assumed that the surrounding walls are cut such that the base of the walls are at the same EL 995-6.
B. All interior walls will be removed UNO.
C. The floor above the sub-basement at EL 971-0 will be removed to expose the entire sub-basement.
D. Any deep footings are excluded from the concrete volume total.
FC-20-006 Revision 0 FCS Bldg End State Concrete Surface Areas & Volumes Page 6 of 52 E. This section includes all items up to, but not including, the Containment exterior wall.
For calculation simplicity, this includes an imaginary line in the foundation, rather than the existing construction joints.
F. The Containment concrete curb volume is included in the volume total for floors and foundations.
