HF Spiking Station #1 Soil Sampling Assessment Report Mrs. Kuhn:
Attached for your review and approval are the Westinghouse Columbia Fuel Fabrication Facility (CFFF or Site) assessment report (Assessment) for the Hydrofluoric Acid Spiking Station (HFSS) #1 as well as the Technical Basis Document (TBD). The Assessment and TBD were prepared by AECOM Technical Services (AECOM) and Leidos, respectively, and document the investigation activities, results and conclusions from completion of the Work Plan which was approved by South Carolina Department of Health and Environmental Controls (SCDHEC or Department) on March 30, 2020. Based on these submittals, CFFF concludes that HFSS #1 is protective of employee health and safety and poses no threat to the public.
 
===Background===
CFFF uses two independent spiking stations referred to as Hydrofluoric Acid Spiking Stations 1 or 2 (HFSS
#1 or HFSS #2). The stations are adjacent to each other and mix hydrofluoric acid with uranyl nitrate (UN) for the conversion process. Previous assessment of HFSS #2 after the discovery in 2018 of a release from this station indicated the presence of uranium (U) within sub-slab soils beneath HFSS #2. Subject to DHECs review and approval, the station was subsequently remediated and returned to normal operation.
Following the HFSS #2 assessment, CFFF completed the following actions to mitigate future issues at the spiking stations in the plant.
* Developed an improved design for both spiking stations and diked areas that prevents spills of process solution from impacting the concrete, protects the concrete with a floor coating that is impervious to acidic materials and guards against undetected deterioration of the concrete floor.
o The improved design for HFSS #2 was implemented and also included a new preventive maintenance strategy.

Page 2 of 4 Our ref: LTR-RAC-20-65 July 30, 2020 To comprehensively assess potential environmental impacts at the CFFF from current and historical operations, the Site also:
* Entered into Consent Agreement (CA) 19-02-HW with SCDHEC in February of 2019 to address environmental impacts originating from facility operations. This included the establishment of eight operational units (OUs) and the installation of sentinel wells. One OU (Chemical Area) includes the portions of the manufacturing building where liquid uranium processing and handling operations occur. A network of sentinel wells was installed around the Chemical Area OU to detect a potential leak or contaminant migration from this area.
* Completed the first phase of a comprehensive Remedial Investigation (RI) performed under the CA, with a final summary report submitted to SCDHEC on July 15, 2020. The results of this assessment show there is no off-site impact from CFFF operations, and the extent of the existing impact is limited, generally well-defined and poses no significant threat to plant workers, the general public or the environment.
* Developed procedure RA-433, Environmental Remediation, using industry best practices to standardize a risk-based, decision-making process for analysis of environmental data and facility response to a release with potential environmental impact. This procedure uses best practices from an industry groundwater protection initiative to prevent migration of material off-site and to minimize decommissioning impacts.
* Developed and implemented a Conceptual Site Model (CSM) to assist CFFF with the assessment of environmental data. The CSM was enhanced using the data from the first phase of the RI, making it a more effective decision-making tool. The CSM coupled with improved environmental monitoring and the remediation procedure provide a robust environmental protection program.
HFSS #1 Investigation Due to the conditions found in HFSS #2 CFFF investigated the conditions of HFSS #1. CFFF submitted for SCDHECs approval a Work Plan for the subsurface investigation of the HFSS #1 area in a letter (LTR-RAC-20-31) dated March 20, 2020. The Department subsequently approved the plan on March 30, 2020.
In accordance with the aforementioned plan and as part of implementation of the improved HFSS #1 design, the concrete floor was removed to construct the new containment dike. Soil samples were collected from May 4-6 of 2020 to evaluate the subsurface conditions. The results of the sampling are included within the Assessment Report prepared by AECOM (Attachment 1).
 
Page 3 of 4 Our ref: LTR-RAC-20-65 July 30, 2020 Calculations of Dose and Risk Following the Sites Environmental Remediation procedure, RA-433 and AECOMs recommendations, CFFF contracted Leidos to evaluate risk and dose to the industrial worker at HFSS #1 resulting from residual uranium beneath the concrete floor. The Technical Basis Document prepared by Leidos and dated July 28, 2020 is attached to this cover letter (Attachment 2).
Conclusions and Further Environmental Evaluation Based on the data provided in the AECOM HFSS #1 Assessment Report and the Leidos TBD, the following conclusion were made:
* Neither fluoride nor nitrate exceeded the CFFF action levels delineated in the Sites Remediation Procedure.
* Tc-99 results were non-detect and further evaluation of Tc-99 was not warranted.
* Uranium results showed exceedances of the remedial action levels, triggering an evaluation of the residual contamination.
* Based on the operating configuration of the HF Spiking Station, the concrete floor slab provides an adequate barrier between the residual U and an industrial worker under current conditions.
* Over the course of the 100-year timeframe that was modeled, the highest dose was calculated at 0.324 mRem/year and the highest Total Excess Cancer Risk (TR) was calculated at 6.47E-6.
* Based on the TBD results, it is acceptable to leave the material in place beneath a 6-in concrete cover at present time and for the next 100 years.
* The current decommissioning cost estimate includes funding for the removal of material beneath the process-building slab in the Chemical Area OU, including the area where the Spiking Stations are located.
* Leaving the residual contamination in-place, with the existing controls and monitoring program poses no risk for off-site impacts.
* Based on the Final Interim RI Data Summary Report, the potential for U to migrate with groundwater has been shown to be limited at the Site.
Closing We look forward to continuing work with SCDHEC to finalize this assessment. CFFF is committed to protecting the safety of its employees, the community, and the environment, and we believe the transparency and ongoing activities being performed under the Consent Agreement demonstrate this commitment. If you have any questions or comments, or if we can be of further assistance, please do not hesitate to contact me or Nancy Parr at (803) 647-3338 or parrnb@westinghouse.com.

==1.0        INTRODUCTION==
 
The Westinghouse Columbia Fuel Fabrication Facility (CFFF) uses two spiking stations, located directly adjacent to each other, where hydrofluoric acid (HF) is mixed with uranyl nitrate for the conversion process. Previous assessment of HF Spiking Station (HFSS) #2 in 2018 after the discovery of a potential release from this station indicated the presence of uranium (U) within subslab soils beneath HFSS #2.
Approximately 76 metric tons of soil from beneath HFSS #2 were excavated and disposed prior to HFSS
#2 being rebuilt. As part of CFFFs extent of condition review, the facility is also upgrading the HFSS #1 to the new design which includes investigation of subslab soil quality beneath HFSS #1 under the Consent Agreement (CA) with the South Carolina Department of Health and Environmental Control (SCDHEC).
The CA, Conceptual Site Model (CSM) and a risk-based site remediation procedure were not in place when the HFSS #2 issue was discovered. This report documents assessment activities related to HFSS
#1.
1.1 Site Background 1.1.1 Site Description The CFFF (the Site") is located at 5801 Bluff Road (SC Hwy 48) near Hopkins, South Carolina (Figure 1). The Site includes approximately 1,151 acres, the majority of which is undeveloped. The developed portion of the property including the plant building, an employee parking area, several smaller support buildings, outdoor supply staging areas, and wastewater lagoons encompasses approximately 75 acres.
The developed area is located approximately 2,700 feet southwest of Bluff Road within the north-central portion of the property. The position of the developed area within the Site creates a substantial buffer from downgradient, adjoining properties. HFSS #1 is located in the south central portion of the plant building.
A manmade dike approximately 1,850 feet south of HFSS #1 backs up water in Mill Creek, creating Lower Sunset Lake. A second manmade dike cuts across Mill Creek creating Upper Sunset Lake. Upper and Lower Sunset Lake are located approximately 1,250 feet southwest of the HFSS #1 (Figure 2) within a natural oxbow of Mill Creek. A small, man-made pond known as the Gator Pond is also located approximately 900 feet southwest of HFSS #1. Surface water drainage on the developed portion of the property is managed by several ditches which empty into Upper Sunset Lake.
The southern portion of the property, including the Gator Pond, and both portions of Sunset Lake (part of Mill Creek) are located within the floodplain of the Congaree River. The plant and the floodplain are separated by a bluff, approximately 20 feet high, located immediately south of the east-west trending dirt road on the plant property.

HF Spiking Station #1 Assessment Report Westinghouse Columbia Fuel Fabrication Facility AECOM Project No. 60633543                                                              Hopkins, South Carolina 1.1.2 Site History The CFFF plant was constructed in 1969 to manufacture fuel assemblies and components for the commercial nuclear power industry. Prior to construction the Site consisted of farmland, woodlands, and floodplain.
As a result of historical operations and the need to further assess environmental impacts, the Site entered into a CA with SCDHEC on February 26, 2019. As discussed in the Final Remedial Investigation Work Plan (AECOM, 2019), CFFF records indicate historic releases in the Chemical Area of the manufacturing building. This area was established as the Chemical Area Operable Unit (OU). The soil underneath this portion of the manufacturing building is known to be radiologically impacted with residual quantities of U.
Because of this, a Chemical Area OU groundwater monitoring well network was established in 2018-2019. Collectively, the monitoring wells and the CSM provide a robust early detection program to monitor the OU for migration of potential impacts from past or future manufacturing operations for the life of the plant.
The HFSS #1 system and containment dike were last replaced in March 2002 following an above ground piping leak in October 2001. The previous containment dike, with interior dimensions of 112 inches by 84 inches, used the exterior manufacturing building wall as one of its four sides. The replacement project included moving the south wall of the dike approximately 12 inches from the exterior building wall.
Seventeen 55-gallon drums of concrete floor and subsurface soils were removed to install the new containment dike. The event was documented in the Sites decommissioning records in 2001 and was incorporated into the initial CSM included with the Final Remedial Investigation (RI) Work Plan approved in June 2019 (AECOM, 2019).
1.2 Site Investigation Objective As part of the CA, CFFF is performing an RI to understand the source, nature and extent of impacts, resulting from current and historical operations at the Site. The first phase of the investigation has been completed and supported the conclusion that there are no known offsite impacts from plant operations.
CFFF is currently developing the scope of work to be proposed to SCDHEC for the second phase of the RI.

HF Spiking Station #1 Assessment Report Westinghouse Columbia Fuel Fabrication Facility AECOM Project No. 60633543                                                              Hopkins, South Carolina 2.0      SITE INVESTIGATION ACTIVITIES This section discusses the rationale and methods used during the soil investigation. AECOM Technical Services, Inc (AECOM) performed the soil assessment in HFSS #1 from May 4, 2020 to May 6, 2020.
The investigative efforts were performed to determine if subsurface soils and plant building footers have been impacted by potential releases from HFSS #1.
2.1 Field Investigation Activities Field investigation activities included the following:
* Installation of 5 vertical hand auger borings (HF1-B1 through HF1-B5) to collect soil samples from beneath HFSS #1 footprint; and
* Installation of 2 angled hand auger borings (HF1-B6 and HF1-B7) to collect soil samples within and adjacent to the HFSS #1 footprint that were also in close proximity to the building footer for structural engineering evaluation.
2.1.1 Soil Assessment To protect CFFF workers outside of the HFSS #1 study area from potential exposure to dust generated during concrete removal and soil disturbance, a tented structure was set up around the work station. A temporary berm was also installed on the floor to keep potential spills from outside of the study area from reaching the exposed subslab soil.
Seven (7) borings (HF1-B1 through HF-B7) were advanced using dedicated stainless steel hand augers within the HFSS #1 study area (Figure 3). These borings were advanced to hand auger refusal or a depth of 10 feet below soil surface (bss), whichever was less. The depth to the water table below HFSS
#1 is approximately 12 feet bss. Boreholes HF1-B4, HF1-B6, and HF1-B7 encountered hand auger refusal at depths ranging from 5.08 feet to 5.37 feet bss.
Composite soil samples were collected from the following intervals: 1-2 feet bss, 3-4 feet bss, 5-6 feet bss, 7-8 feet bss, and 8-10 feet bss, with the exception of borings where hand auger refusal was encountered at shallower depths. The top foot of soil generated at each boring was discarded because the surface of the soil beneath the concrete was likely cross contaminated with Uranium (U) during the cutting and removal of the concrete floor. The concrete floor in this area is known to contain elevated U concentrations.
When pulling the hand auger bucket out of the borehole and pushing the hand auger bucket back into the borehole, soil from the sidewalls of the borehole could have collapsed into the bottom of the borehole. To ensure that representative samples were collected from the desired depths, AECOM personnel used a tape measure before and after each advancement of the hand auger bucket within the sample interval to document how much soil within each retrieved hand auger bucket was native soil at a given depth. Soil from the top of the hand auger bucket was emptied into 3-gallon plastic bags until only the measured increase in the total borehole depth remained within the hand auger bucket.

HF Spiking Station #1 Assessment Report Westinghouse Columbia Fuel Fabrication Facility AECOM Project No. 60633543                                                                Hopkins, South Carolina One grab sample (HF1-B7 REFUSAL) was collected at the refusal depth of borehole HF1-B7 to assess pH at the depth that is believed to be the top of the plant buildings footer.
Soil from the composite sample intervals was emptied from the hand auger bucket onto a 3 foot by 3 foot 4-mil polyethylene plastic mixing square, dedicated to the specified sampling interval, and homogenized.
Homogenized soil samples were placed in pre-cleaned, laboratory-provided sample bottles.
After the soil samples were collected from HF1-B6 and HF1-B7, CFFF and AECOM personnel used the hand auger extension rods and a plumb bob to obtain measurements that would allow for the assessment of the angle at which boreholes B-6 and B-7 extended into the subsurface, the depth below soil surface of the sampling intervals, and how far from the borehole opening each borehole extended towards the plant buildings footer.
Subsurface lithology from each borehole was logged by an AECOM geologist. Boring logs are included in Appendix A.
2.1.2 Soil Sample Analysis and Results Soil samples were submitted to GEL Laboratories, LLC (GEL) for analysis of percent moisture using ASTM D 2216 (Modified), fluoride and nitrate using EPA Method 9056A, isotopic U using EPA DOE EML HASL-300 (U-02-RC Modified), technetium 99 (Tc-99) using DOE EML HASL-300 (Tc-02-RC Modified) and pH using EPA Method 9045D. Soil analytical results and the depth bss of the samples are summarized in Table 1 and displayed on Figure 3. Laboratory analytical results are contained in Appendix B.
Soil from borings HF1-B1, HF1-B3, HF1-B5, and HF1-B7 contained uranium above the Site-specific remediation action level (RAL), as documented in the facilitys Procedure RA-433 Environmental Remediation Revision 1 (CFFF, 2020), with the greatest impact encountered in soil samples from boreholes HF1-B1 and HF1-B3 at depths ranging from two feet bss to eight feet bss. The Site-specific RAL incorporates established regulatory screening levels that are protective of human health and the environment for decision making purposes. Impact in soil within boreholes HF1-B1 and HF1-B3 increased from the surface to the greatest impact in the 4-6 feet sampling interval and decreased thereafter.
Surficial soils from the two angled borings (HF1-B6 0-2 foot and HF1-B7 0-2 foot) were intended to be analyzed for pH only due to potential cross contamination with U impacted concrete from the floor.
However, the chain of custody for the surficial composite soil sample from HFSS1-B7 0-2 foot was errantly marked to also analyze soil from this interval for fluoride, nitrate, Tc-99 and U. Analytical results from the 0-2 foot interval in samples HFSS-1 B6 and HFSS-1 B-7 are similar to the analytical for the surface soil samples from the 1-2 foot interval for HFSS-1 B1 through HF1-B5.

==3.0      CONCLUSION==
S Based upon the results of this assessment, AECOM concludes the following:
* Some of the soil below the concrete floor within the HFSS #1 area is impacted with fluoride, nitrate, and uranium, and has areas of low pH (<5 standard units). This data is representative of other soils below the Chemical Area OU.
* In general, surficial soils (0-2 feet bss) had minimal impact from the operations of HFSS #1. This is likely due to the dike replacement early 2002. Based on the minimal impact in the shallow surficial soil beneath the concrete slab, operations of HFSS #1 do not appear to have impacted these soils since this replacement.
* Soil from borings HFSS1-B1, HFSS1-B3, HFSS1-B5, and HFSS1-B7 exceed the Site-specific remedial action levels. Based upon the facilitys Procedure RA-433 Environmental Remediation Revision 1, the following evaluations should be undertaken:
: 1. Complete dose/risk assessment under current circumstances (industrial worker scenario).
: 2. Determine the potential for off-site impacts if the impacted soil is left in place.
: 3. Complete an assessment of Site conditions and future use of the area.
The results of these evaluations are documented in the Technical Basis Document prepared by Leidos (Leidos, 2020).

Data Summary:
All sample data provided in this report met the acceptance criteria specified in the analytical methods and procedures for initial calibration, continuing calibration, instrument controls and process controls where applicable, with the following exceptions.
Quality Control (QC) Information Matrix Spike (MS)/Post Spike (PS) Recovery Statement The percent recoveries (%R) obtained from the spike analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. The matrix spike recovered outside of the established acceptance limits due to matrix interference and/or non-homogeneity.
Analyte                Sample                      Value Fluoride 1204556273 (HF1-B1-(1-2)MS) 46.8* (75%-125%)
Technical Information Sample Dilutions The following samples 1204556272 (HF1-B1-(1-2)DUP), 1204556273 (HF1-B1-(1-2)MS), 510581001 (HF1-B1-(1-2)), 510581002 (HF1-B1-(2-4)), 510581003 (HF1-B1-(4-6)), 510581004 (HF1-B1-(6-8)) and 510581005 (HF1-B1-(8-10)) were diluted because target analyte concentrations exceeded the calibration range.
Dilutions may be required for many reasons, including to minimize matrix interferences or to bring over range target analyte concentrations into the linear calibration range.

Counting Uncertainty is calculated at the 95% confidence level (1.96-sigma).
The Qualifiers in this report are defined as follows:
    **    Analyte is a Tracer compound
    <    Result is less than value reported
    >    Result is greater than value reported BD    Results are either below the MDC or tracer recovery is low FA    Failed analysis.
H    Analytical holding time was exceeded J    See case narrative for an explanation J    Value is estimated K    Analyte present. Reported value may be biased high. Actual value is expected to be lower.
L    Analyte present. Reported value may be biased low. Actual value is expected to be higher.
M    M if above MDC and less than LLD M    REMP Result > MDC/CL and < RDL N/A RPD or %Recovery limits do not apply.
N1    See case narrative ND    Analyte concentration is not detected above the detection limit NJ    Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Q    One or more quality control criteria have not been met. Refer to the applicable narrative or DER.
R    Sample results are rejected U    Analyte was analyzed for, but not detected above the MDL, MDA, MDC or LOD.
UI    Gamma Spectroscopy--Uncertain identification UJ    Gamma Spectroscopy--Uncertain identification UL    Not considered detected. The associated number is the reported concentration, which may be inaccurate due to a low bias.
X    Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y    Other specific qualifiers were required to properly define the results. Consult case narrative.
    ^    RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL. Qualifier Not Applicable for Radiochemistry.
h    Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more or %RPD not applicable.
^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptance criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.
* Indicates that a Quality Control parameter was not within specifications.
For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.

PURPOSE The purpose of this Technical Basis Document (TBD) is to evaluate the risk and dose to the industrial worker at Spiking Station #1 resulting from residual uranium beneath the concrete floor.
Since the WCFFF is an operating manufacturing plant, the levels do not need to be reflective of an unrestricted use area (10 CFR 20.1402), as would be required for decommissioning, but rather, should be established to protect the workers, be as low as reasonably achievable (ALARA), and be protective of the environment to prevent leaching of residual uranium into groundwater.
HF Spiking Station #1:
In May of 2020, as part of the floor replacement beneath Spiking Station #1, soil samples were collected to evaluate the subsurface conditions. Samples were taken from 2-foot intervals from 7 locations beneath the concrete floor of Spiking Station #1. Soil was collected to a depth of 10 feet, except in cases where the sampling device encountered refusal (HF1-B4, -B6, and B7). Two of the sample locations were set at an angle to intercept the known footing (HF1-B6 and -B7). Soil samples were submitted to GEL Laboratories for isotopic Uranium (U) and Technetium -99 (Tc-99) analysis along with corrosivity, fluoride, nitrate, and moisture content. This report focuses on the radiological contaminants U and Tc-99; however, it was noted that neither fluoride nor nitrate exceeded the CFFF action levels (Procedure RA-433) shown in Table 1 below.

Tc-99 results were non-detect and further evaluation of Tc-99 was not warranted. Uranium results showed exceedances of the CFFF action levels triggering an evaluation of the residual contamination.
Because multiple isotopes of uranium were detected in the soil samples, a sum of fractions or SOF approach was used to determined compliance. The Sum of Fractions screening was initially compared to the SSLs presented in Table 2 of Procedure RA-433. Six of the seven sample locations contained sample intervals with SOF calculations exceeding 1.0. Therefore, the laboratory results for each samples were then compared to the action levels provided in Table 1 above [from Table 4 of procedure RA-433 (Section 5.2.4 2
 
E)]. The SOF for each soil sample was calculated using the concentration for each isotope and the Action Level for each isotope. The calculation for each unique sample used the following equation:
                                . 234 . 235 . 238
                        =                    +                    +
3,310                  39                  179 A SOF result exceeding 1.0 indicates that the action levels have not been met. SOF calculations for each sample interval are shown in Table 2, with SOF calculations exceeding 1.0 in bold. All sample locations, with the exception of HF1-B2, had at least one sample interval where the SOF exceeded 1.0. Since both individual isotopes exceeded action levels and sample locations exceeded an SOF of 1.0, further evaluation of the effects of leaving residual uranium beneath the spiking station was warranted.
Per RA-433, further evaluation included:
* Calculation of dose and risk under the current circumstances (industrial worker scenario);
* Evaluation of the potential for off-site impacts if the contamination is left in place; and
* Assessment of the site conditions and future use of the area.
CALCULATION OF DOSE AND RISK RESRAD-ONSITE Version 7.2 was used to calculate potential dose and risk to the evaluated receptor.
RESRAD-ONSITE (formerly RESRAD) is a computer model developed by the Argonne National Laboratory (ANL) for the U.S. Department of Energy (DOE). RESRAD-ONSITE calculates site-specific risk and dose to various future hypothetical on-site receptors at sites with residual radioactive materials.
The use of the RESRAD family of codes for modeling risk and dose has become an acceptable regulatory standard. RESRAD-ONSITE Version 7.2 incorporates recently (2014) updated dose conversion and morbidity slope factors calculated by Oak Ridge National Laboratory (ORNL). These updated factors are presented in the ORNL document entitled Calculation of Slope Factors and Dose Coefficients (ORNL 2014) and are included in the DCFPAK 3.02 library of the RESRAD-ONSITE Version 7.2 model. The derivations of these factors are based on updated decay chain and nuclide energy data presented in International Commission on Radiological Protection Publication (ICRP)-107, Nuclear Decay Data for Dosimetric Calculations (ICRP 2008).
Uranium was detected in all the samples collected from the soil under Spiking Station #1. Three of the seven sample locations (HF1-B2, HF1-B4, and HF1-B6) did not have samples that exceeded the Action Level. The remaining four locations (HF1-B1, HF1-B3, HF1-B5, and HF1-B7) had at least one sample interval where the levels of uranium exceeded the action level for at least one isotope. Figure 1 below shows the sample locations within the HSFF#1 footprint. Table 2 below contains the isotopic uranium results for the samples collected. Exceedances of the action levels are shown in bold typeface.

In order to calculate the dose and risk using RESRAD-ONSITE, an estimate of the residual contamination needed to be calculated. Because the contamination is not homogeneous either vertically or horizontally, it was determined that the model would be based on 2 foot thick layers of impacted soil. The residual U in each layer was conservatively estimated by calculating the 95% Upper Confidence Level (UCL) for each 2-foot interval. The 95% UCL provides a reasonable confidence that the true concentration average will not be underestimated. This is important given the heterogeneity of the material and the variability of the sampling results. The RESRAD-ONSITE model was then executed for each 2-foot layer and the dose and risk contribution from each layer was summed to account for a total dose and risk. The 95% UCL concentrations of U-isotopes used for each 2-foot layer are shown in Table 3.

As each layer was modeled, the protective cover included the 6-inch concrete layer and the depth of overlying soil. For example, the 0 to 2-foot interval was modeled with only the concrete floor as a cover, while the 2-4 foot layer was modeled with the concrete floor plus 2 feet of soil. This process was continued until the final layer (8-10 feet) was modeled with the concrete and 8 feet of soil.
Additionally, the concrete floor within the spiking station diked area will have a chemical resistant non-permeable coating covering the floor and the dike once restored. This coating will be a Milimar Coatings 6200 FS, which is a highly chemical resistant, multi-layered Novolac Vinyl Ester laminate flooring system, built up to approximately 1/4 inch (250 mils) thick. The monolithic surface is resistant to concentrated chemicals, thermal shock and abrasion. This coating creates not only a barrier for chemical migration downward into the concrete, but also prevents upward radon migration through the concrete floor and into the indoor air. However, for conservativeness, no credit was taken for this coating during the dose and risk calculations for the spiking station.
The radon pathway was set as active for the dose and risk modeling. It is understood that there are relative uncertainties of the model predictions for radon; however, the predictions are still valuable in estimating the protectiveness. RESRAD-ONSITE does contain parameters that can be adjusted to specific building design characteristics, but actual radon migration does not necessarily adhere to the parameters and transport mechanisms within the model. Indoor radon concentrations are driven by meteorological conditions, indoor heating and air conditioning practices, local geological characteristics, structural air spaces and airflow conduits, seasonal variances, and other factors. For this TBD, the default RESRAD parameters for radon were used with the exception of the air changes per hour, and wind speed. Spiking Station #1 is located in an area of the facility that is kept under negative air pressure. The actual air changes with the area are maintained at a minimum of 6 per hour, versus the default of 0.5 air changes per hour in the RESRAD model. Also, the wind speed parameter, found on the Cover and Contaminated Zone Hydrological Data window within the program model, is used for radon dose calculation. The default for wind speed is 2 meters per second and is based on outdoor conditions. Since the spiking station is indoors, the wind speed was reduced from 2 meters per second to 0.15 meters per second. This deviation from the default wind speed was a more conservative approach because overall airflow is created by designed ventilation systems.

Although not accounted for in the model, the chemical resistant coating will provide additional means of preventing radon migration from the soil through the floor slab. Accounting for the coating would reduce the overall cover permeability and the emanation coefficient for radon, thereby lowering the calculated risk.
As these parameters could not be definitively assessed, the default numbers were used in the model, leading to another layer of conservativeness.
The spiking station itself is contained within a building structure, which prevents any precipitation from providing a migration driver for the residual contamination to the underlying groundwater. Additionally, the floor of the spiking station is raised approximately 4 feet above the natural ground surface, providing approximately 12 feet of unsaturated material between the base of the spiking station and the groundwater.
With no mode of force driving the residual U vertically, the building and concrete floor provide an impervious engineered barrier. The concrete floor covering also provides a protective barrier between the industrial worker and the residual U, lowering any potential risk. If conditions change, such that sub-slab excavation and work becomes necessary, the utility worker scenario will require evaluation.
Tables 4 and 5 present the dose and risk calculations from the RESAD model for each 2-foot layer and modeled duration. The individual 2-foot layer results are then added to determine the total dose (Table 4) and risk (Table 5) for each modeled year. Based on the results of the RESRAD model, shown in Tables 4 and 5 above, the residual U does not currently pose a threat to human health and the environment, nor will it pose a threat over the next 100 years. Over the course of the 100-year timeframe that was modeled, the highest dose was calculated at 0.324 mRem/year and the highest Total Excess Cancer Risk (TR) was calculated at 6.470E-6. Both of these maximums occur at year 100. Based on these model results, it is acceptable to leave the material in place beneath a 6-in concrete cover at present time and at least for the next 100 years. Currently, the life span of the facility is not known, but can be reasonably assumed to be less than 100 years. At the time of facility decommissioning, the soil beneath the process building, including soil at this location, will be removed and disposed of off-site as outlined in the Westinghouse CFFF Decommissioning Funding Plan (WDD-PD-00591-CFFF).

In its current configuration, there is not a mode of force to cause migration of the uranium vertically into the groundwater. Additionally, the potential for uranium to migrate with groundwater has been shown to be limited at the CFFF site. If monitoring, as described below, indicates that migration or uranium from beneath the process building is occurring, it will be corrected/remediated before it reaches the facility boundary.
The primary mechanism for contaminant transport is migration with water. Contaminants generally move as a solution in water, based on solubility, and their rates of migration are controlled by both water migration rates and by sorption and desorption reactions involving the surrounding soils. Some contaminants are strongly sorbed on soils, thus migration is significantly retarded. The equilibrium distribution coefficient (Kd [cm3/g]) is defined as the amount of contaminant absorbed into soil divided by the amount remaining in solution. Contaminants with a low Kd are more readily transported through the soil than those with a high Kd.
Site-specific Kd values for contaminants at CFFF have not been established. It may be prudent to conduct site-specific studies prior to the final decommissioning, when unrestricted release criteria will be met, but in the interim, literature values, combined with knowledge of site geology will be sufficient as they are generally lower (more conservative) than the site-specific values and therefore predict greater mobility than would actually occur.
Soil type has a significant impact on the published values of Kd. NUREG/CR-6697 separates Kd values by soil type based on Sheppard and Thibault (1990). The Sheppard and Thibault ranges grouped by soil type for uranium are: Sand - 0.03 to 2,200 cm3/g (mean 35); Loam - 0.22 to 4,500 cm3/g (mean 15); Clay 395,100 cm3/g (mean 1,600); and Organic - 33 to 7,350 cm3/g (mean 410).
Further literature review provided the following distribution coefficients (Kd) for Uranium across all soil types. (Source Table 3-13, EPA 402-R-96-011A).
* EPA Best Case - 15 cm3/g
* RESRAD Version 7.2 Default - 50 cm3/g
* NUREG/CR-5512 Default - 15 cm3/g
* Proposed EPA Median Value - 220 cm3/g 8
 
Based on the Remedial Investigation Report (AECOM 2013), the uppermost geologic formation is composed of a stratified, but poorly sorted, mixture of alluvial clay, silt, sand, and gravel. These layers can generally be differentiated into an upper firm clay/silty sand and a lower loose sand/silty sand unit.
Potentiometric surface maps indicate that the unsaturated zone is the firm clay/silty sand with the saturated zone being primarily the loose sand/silty sand layers. Based on this interpretation, the residual impact at CFFF is within the clay/silty sand and would need to migrate downward into the saturated zone to have a detrimental impact on the groundwater within the loose sand/silty sand layer. Due to the spiking station being beneath a building roof and concrete floor, there is not infiltration from precipitation creating a mode of force. Using the RESRAD default Kd for uranium is appropriate until the site enters into decommissioning, at which time a site-specific study may be performed.
The oxidizing and pH conditions also affect the mobility of contamination with the subsurface. Under oxidizing conditions, anticipated to be similar to the surface soils at CFFF, dissolved U is predicted to exist as a cation up to a pH of approximately 6; as a neutral hydroxide species from a pH of 6 to 8, and as an anionic carbonate above a pH of 8 (PNL 1995). This suggests that U would sorb, via cation exchange, under conditions observed at CFFF, resulting in a higher Kd, indicating that the migration of U is significantly retarded. Comingling of contamination, such as nitrate, can have an effect on the transport of U; however, the nitrate contamination at CFFF is not collocated with U. If a nitrate plume or other conditions, such as pH extremes, are identified in the future, a re-evaluation may be required.
Verification that there are no off-site impacts will be confirmed through monitoring and inspection.
Monitoring of the groundwater downgradient from HF Spiking Station #1 will be conducted on a regular basis as part of the site-wide groundwater-monitoring program. The results will be reviewed and compared to historic levels to detect any increases in U that could be attributed to the residual U beneath Spiking Station #1. Monitoring wells have been installed around the east, south, and west sides of the process building to monitor potential contaminant migration from beneath the process building, including contamination beneath the spiking station. These wells serve as an early detection system of groundwater impacts from the residual U beneath HF Spiking Station #1 as well as any potential future releases.
An inspection program is in place to evaluate the status of engineered controls at HF Spiking Station #1.
The program is designed to ensure that the concrete floor which provides a protective cover, remains in place and is functional. In addition, the chemical resistant coating on the concrete in the diked area will also be inspected on an annual basis.
RESIDUAL URANIUM AND ENGINEERING CONTROL REGISTRY The results of the current soil sampling event will be kept in the site registry until the time of site decommissioning. This registry will be included in the WCFFF site procedure (RA-137 Decommissioning Recordkeeping) and will conform to the requirements of 10 CFR 20.1501. The registry should include a description of the location and nature of the residual U, the concentrations remaining, an estimate of the mass remaining, the controls necessary to retain protectiveness, and a list of the downgradient wells used to monitor for potential migration.

CONCLUSIONS AND RECOMMENDATIONS Based on the operating configuration of the HF Spiking Station, the concrete floor slab provides an adequate barrier between the residual U and an industrial worker under current conditions. Over the course of the 100 year timeframe that was modeled, the highest dose was calculated at 0.324 mRem/year and the highest Total Excess Cancer Risk (TR) was calculated at 6.47E-6. Both of these occur at year 100. Based on these model results, it is acceptable to leave the material in place beneath a 6-in concrete cover at present time and for the next 100 years. Since the facility will likely be decommissioned prior to this timeframe, there is no need to remove the contaminated soil at this time. The current decommissioning cost estimate includes funding for the removal of material beneath the process-building slab, including the area of each HF Spiking Station.
