SUMMARY

This Final Status Survey (FSS) Release Record for survey unit L1-SUB-TDS, West Excavation (within open land survey unit L1-010-102), has been generated in accordance with LaCrosseSolutions procedure LC-FS-PR-009, Final Status Survey Data Reporting (Reference 1) and satisfies the requirements of Section 5.11 of the La Crosse Boiling Water Reactor License Termination Plan (LTP) (Reference 2). An FSS sample plan for this survey unit was developed in accordance with LaCrosseSolutions procedure LC-FS-PR-002, Final Status Survey Package Development (Reference 3), the LACBWR LTP, and with guidance from NUREG-1575, Revision 1, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (Reference 4). This survey unit has a MARSSIM classification of 1. A survey plan was designed based upon use of the Sign Test as the nonparametric statistical test for compliance. Both the Type I () and Type II () decision error rates were set at 0.05. As a systematic sample population using a random start point, fourteen (14) soil samples were acquired from the survey unit. In addition, soil scanning was performed on 100% of the total surface area in the survey unit. The analytical results for all soil samples taken in survey unit L1-SUB-TDS indicate that the maximum Sum-of-Fraction (SOF), considering the concentration of all applicable Radionuclides of Concern (ROC) either by direct measurement or by inference, is equal to 0.0552 when applying the respective Operational Derived Concentration Guideline Levels (OpDCGLS) for soil. Therefore, the null hypothesis is rejected and survey unit L1-SUB-TDS is acceptable for unrestricted release. The mean SOF when applying the respective Base Case DCGLs (DCGLS) for soil is 0.0125. This SOF equates to a dose for the survey unit of 0.3115 mrem/yr.

2. SURVEY UNIT DESCRIPTION L1-SUB-TDS is an impacted Class 1 excavation survey unit. The survey unit consists of the underlying soil post-removal of the Turbine Building/Turbine Building Offices and 1B Diesel Generator Building, as well as associated system lines. The surface area of the survey unit is 1,185.5 m2.

The boundary of the survey unit and the location of the soil samples were defined using a Global Positioning System (GPS). Refer to Attachment 1 of this report for figures and maps depicting survey unit L1-SUB-TDS. 5

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS This survey unit includes only the western portion of the original L1-SUB-TDS. The eastern portion of the original survey unit did not undergo FSS because of high background readings emanating from the Reactor Building and surrounding environs. The eastern portion of the survey unit (now identified as L1-SUB-TDS A) will undergo FSS under a separate sample plan. Additionally, the Reactor Plant Generator Plant Area (RPGPA) Sump Area, also within the east portion of the original survey unit, experienced groundwater intrusion due to rising Mississippi River levels and has caused it to become inaccessible. The backfilled RPGPA Sump Area (L1-SUB-TDS B) will undergo FSS via use of GeoProbe technology using a separate sample plan.

3. CLASSIFICATION BASIS Based on the Historical Site Assessment (HSA) (Reference 5), open land survey unit L1-010-102 had a past history of minor radiological surface contamination on the grounds and outside the truck bay and therefore was categorized as a Class 1 area. As survey unit L1-SUB-TDS consists of the underlying soils from L1-010-102, it is also deemed Class 1. The following summarizes the results of the characterization surveys for survey unit L1-010-102.

The initial site characterization surveys performed by EnergySolutions were conducted between October 9, 2014, and August 6, 2015. In 2014, a total of two (2) surface soil samples, and seven (7) subsurface soil samples (including one sub-slab soil sample taken beneath the Turbine Building Tunnel Area) were collected in the survey unit. In 2015, as part of a broader site characterization, five (5) locations were selected for angled coring to obtain soil from beneath the Turbine Building at the location of suspected broken drain lines. GeoProbe technology was used to obtain the samples. At each of the 5 locations, samples were collected from the 10, 15 and 20 depths, for a total of fifteen (15) soil samples. A total of 2 surface soil samples and 22 subsurface soil samples were collected in the survey unit prior to FSS. All samples were analyzed by the on-site gamma spectroscopy system. No ROC were detected at concentrations above Minimum Detectable Concentration (MDC) for the surface soil samples. For subsurface soil samples, Cs-137 was detected at concentrations above MDC in four (4) of the samples, at a maximum concentration of 0.130 pCi/g. Co-60 was not detected at concentrations above MDC for subsurface soil samples. A summary of the analyses for the surface soil and subsurface soil samples taken during site characterization are presented in Table 3-1. 6

The subsurface soil samples were analyzed for the full suite of initial ROC, while the surface soil sample was analyzed for Co-60, Nb-94, Cs-137, Eu-152, Eu-154, Eu-155, and Am-241. For subsurface samples, H-3 was identified in two (2) samples and Ni-63 was identified in one (1) sample at maximum concentrations of 24.7 pCi/g and 4.0 pCi/g; respectively. No ROC were identified with concentrations greater than MDC for surface soil samples.

In September of 2017, the Turbine Building foundation was removed in its entirety, including all broken drain lines and adjacent soil. As required by Section 5.3.3.4 of the LTP, in the western portion of the excavation, a total of eight (8) samples were collected from the region beneath the broken drain lines, turbine sump, turbine pit, and condenser pit. Although part of continuing characterization, these samples were collected as judgmental samples during the FSS. As per Section 5.1 of the LTP, all samples were analyzed by the on-site gamma spectroscopy system. Gamma spectroscopy results revealed eight (8) samples above MDC for Cs-137 with a maximum concentration of 0.188 pCi/g. Two (2) samples were above MDC for Co-60 with a maximum concentration of 0.257 pCi/g. No samples were identified with concentrations greater than MDC for any other ROC. A summary of the on-7

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS site analytical results for the judgmental soil samples for continuing characterization is provided in Table 7-5. Section 5.1 of the LTP states that the actual Insignificant Contributor (IC) dose will be calculated for each individual sample result using the DCGLs from TSD RS-TD-313196-004, LACBWR Soil DCGL, Basement Concrete DCGL, and Buried Pipe DCGL, Table 4 (Reference 6) for soil. If the IC dose calculated is less than the IC dose assigned for DCGL adjustment, then no further action is required to be taken. If the actual IC dose calculated from the sample result is greater than the IC dose assigned for DCGL adjustment, then a minimum of five (5) additional investigation samples will be taken around the original sample location. Each investigation sample will be analyzed by the on-site gamma spectroscopy system and sent for HTD analysis (full suite of radionuclides from LTP Table 5-1). As with the original sample, the actual IC dose will be calculated for each investigation sample. In this case, the actual calculated maximum IC dose from an individual sample observed in the survey unit will be used to readjust the DCGLs in that survey unit. If the maximum IC dose exceeds 10%, then the additional radionuclides that were the cause of the IC dose exceeding 10% will be added as additional ROC for that survey unit. The survey unit-specific DCGLs used for compliance, the ROC for that survey unit, and the survey data serving as the basis for the IC dose adjustment are required to be documented in the release record for the survey unit. Although four (4) of the samples were required to be sent off-site for Sr-90 analysis (per the FSS sample plan), as a conservative measure, all were sent off-site for Sr-90 analysis. Additionally, seven (7) of the eight (8) samples were sent off-site for HTD analyses for the full initial suite of ROC. An assessment of the results of continuing characterization confirmed that the IC dose is unchanged (dose fraction less than 10%). A summary of the off-site analytical results for the judgmental soil samples collected for Continuing Characterization is provided in Table 7-4. Based upon review of the historical information, the results of the characterization survey data, and completion of a final Survey Unit Classification Worksheet, the correct final classification of survey unit L1-SUB-TDS was determined to be Class 1. Between December 18, 2017, and December 21, 2017, a Remedial Action Support Survey (RASS) was performed in the survey unit after the excavation was complete and before FSS was performed. The purpose of the RASS was to ensure that residual radionuclide concentrations in the excavation were below the Operational DCGL for soil. 100% of the surface area of soil in the excavation was scanned using a Ludlum Model 2350-1 data logger paired with a Ludlum Model 44-10 detector. The alarm set point (ASP) was set using a gross background of 31,800 cpm and a minimum detectable count rate (MDCR) of 1,906 cpm for a total of 33,706 cpm. One (1) alarm was produced and verified during the RASS scan 8

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS survey. In accordance with the RASS sample plan, five (5) judgmental soil samples were collected in the excavation at areas where scan alarms occurred or where significant increases in count rate were noted. The five (5) samples were analyzed using the on-site gamma spectroscopy system. Gamma spectroscopy revealed Cs-137 concentrations ranging between 3.94E-02 pCi/g and 6.74E-01 pCi/g. Co-60 concentrations ranged between 4.30E-01 pCi/g and 5.52E-01 pCi/g. Areas that alarmed and where judgmental samples were collected were bounded and remediated to levels below the Operational DCGL. Remediation was deemed sufficient as no further alarms were produced upon rescan of the elevated areas.

4. DATA QUALITY OBJECTIVES Final Status Survey planning and design hinges on coherence with the Data Quality Objective (DQO) process to ensure, through compliance with explicitly defined inputs and boundaries, that the primary objective of the survey is satisfied. The DQO process is described in the LACBWR LTP in accordance with MARSSIM. The appropriate design for a given survey was developed using the DQO process as outlined in Appendix D of MARSSIM. A summary of seven steps of the DQO process are outlined as follows.

The DQO process incorporated hypothesis testing and probabilistic sampling distributions to control decision errors during data analysis. Hypothesis testing is a process based on the scientific method that compares a baseline condition to an alternate condition. The baseline condition is technically known as the null hypothesis. Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided for rejection. In designing the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria. Rejection of the null hypothesis would indicate that residual activity within the survey unit does not exceed the release criteria. Therefore, the survey unit would satisfy the primary objective of the FSS sample plan. The primary objective of the FSS sample plan was to demonstrate that the level of residual radioactivity in survey unit L1-SUB-TDS did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA). LaCrosseSolutions TSD RS-TD-313196-001, Radionuclides of Concern during LACBWR Decommissioning (Reference 7) established the basis for an initial suite of potential ROC for decommissioning. LTP Chapter 2 provides detailed characterization data that describes the results of surveys taken of soil. Surface and subsurface soil samples were taken in each impacted open land survey units and analyzed for the presence of plant-derived 9

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS radionuclides. The results of surface and subsurface soil characterization in the impacted area surrounding LACBWR indicate that there is minimal residual radioactivity in soil. Insignificant dose contributors were determined to be consistent with the guidance contained in Section 3.3 of NUREG-1757, Volume 2, Revision 1, Consolidated Decommissioning Guidance - Characterization, Survey, and Determination of Radiological Criteria, Final Report (Reference 8). In all soil and concrete scenarios, Cs-137, Co-60, Sr-90, Eu-152 and Eu-154 contribute nearly 100% of the total dose. The remaining radionuclides were designated as insignificant dose contributors and are eliminated from further detailed evaluation. Therefore, the final ROCs for LACBWR soil, basement concrete and buried piping are Cs-137, Co-60, Sr-90, Eu-152 and Eu-154. LTP Chapter 6, Section 6.14.1 discusses the process used to derive the ROC for the decommissioning of LACBWR, including the elimination of insignificant dose contributors from the initial suite. Table 4-1 presents the ROC for the decommissioning of soil at LACBWR and the normalized mixture fractions based on the radionuclide mixture. Table 4 Dose Significant Radionuclides and Mixture for Soil Fraction of Total Activity Radionuclide (normalized)(1) Co-60 0.064 Sr-90 0.098 Cs-137 0.829 Eu-152 0.005 Eu-154 0.003 (1) Based on maximum percent of total activity from Table 22 of RS-TD-313196-001, normalized to one for the dose significant radionuclides. LTP, Section 5.2 states that each radionuclide-specific Base Case DCGL is equivalent to the level of residual radioactivity (above background levels) that could, when considered independently, result in a Total Effective Dose Equivalent (TEDE) of 25 mrem/yr to an Average Member of the Critical Group. To ensure that the summation of dose from each source term is 25 mrem/yr or less after all FSS is completed, the Base Case DCGLs are reduced based on an expected, or a priori, fraction of the 25 mrem/yr dose limit from each source term. The reduced DCGLs, or Operational DCGLs can be related to the Base Case DCGLs as an expected fraction of dose based on an a priori assessment of what the expected dose should be based on the results of site characterization, process knowledge, and the extent of planned remediation. The Operational DCGL is then used as the DCGL for the FSS design of the survey unit (calculation of surrogate DCGLs, investigations levels, etc.). Details of the Operational DCGLs derived for each dose component and the basis for the 10

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS applied a priori dose fractions are provided in LC-FS-TSD-002, Operational Derived Concentration Guideline Levels for Final Status Survey (Reference 9). The dose contribution from each ROC is accounted for using the SOF to ensure that the total dose from all ROC does not exceed the dose criterion. A Base Case DCGL that is established for the average residual radioactivity in a survey unit is equivalent to a DCGLW. The DCGLW can be multiplied by Area Factors to obtain a Base Case DCGL that represents the same dose to an individual for residual radioactivity over a smaller area within a survey unit. At LACBWR, compliance is demonstrated through the summation of dose from five (5) distinct source terms for the end-state (basements, soils, buried pipe, above-ground structures, and groundwater). When applied to soil, the DCGLs are expressed in units of activity per unit of mass (pCi/g). For LACBWR, soil is defined as a layer of soil beginning at the surface but extending to a depth of 1 m to allow for flexibility in compliance demonstration if contamination deeper than 0.15 m is encountered. Based on characterization data and historical information, there are no expectations of encountering a source term geometry that is comprised of a clean surface layer of soil over a contaminated subsurface soil layer. EnergySolutions TSD RS-TD-313196-004 and LTP Chapter 6, Sections 6.4 and 6.8 provide the exposure scenarios and modeling parameters that were used to calculate the site-specific soil DCGLs. The adjusted soil DCGLs for the unrestricted release of open land survey units as provided in Chapter 6, Section 6.16.1 are reproduced in Table 4-2. The insignificant dose contributor percentages for the most limiting basement scenario was used to adjust the DCGLs for soil to account for the dose from the eliminated insignificant contributor radionuclides.

The OpDCGLS for the unrestricted release of soil are provided in Table 4-3. 11

Survey instrument response checks were required prior to issuance and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data. As part of the DQOs applied to laboratory processes, analysis results were reported as actual concentrations, therefore, the actual concentrations are used as the recorded FSS result for measurement and/or sample values even if less than the reported MDC. Negative reported concentrations are recorded as zero. Results were not reported as less than MDC (<MDC). Sample report summaries included unique sample identification, analytical method, radionuclide, result, uncertainty, laboratory data qualifiers, units, and the observed MDC. In accordance with the LTP, for laboratory analysis, MDCs less than 10% of the Operational DCGL were preferable while MDCs up to 50% of the Operational DCGL were acceptable. The minimum acceptable MDC for measurements obtained using field instruments was 50% of the applicable Operational DCGL.

5. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. Guidance for preparing FSS plans is provided in procedure LC-FS-PR-002, Final Status Survey Package Development.

The DQO process validated that Co-60, Sr-90, Cs-137, Eu-152, and Eu-154 would be the ROC in survey unit L1-SUB-TDS as presented in LTP Section 5.1. During the data analysis of the FSS results, concentrations for the HTD ROC Sr-90 are inferred using a surrogate approach. Cs-137 is the principle surrogate radionuclide for Sr-90. During characterization, both Sr-90 and Cs-137 was positively detected in all thirty (30) concrete core samples 12

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS assessed in the Reactor Building, Tunnel, and Waste Treatment Building. The 95% Upper Confidence Limit (UCL) of the Cs-137 fractions was chosen to represent the overall nuclide mix for soils/buried pipe, the Reactor Building, and the Waste Gas Tank Vault. The surrogate ratio for soil is given in Table 5-1. Table 5 Soil Surrogate Ratio Radionuclides Ratio Sr-90/Cs-137 0.502 The equation for calculating a surrogate DCGL is as follows: Equation 1 1

The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation. This approach was conservative since it included background Cs-137 as part of the sample set.

A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARSSIM in support of the decommissioning license termination rule (10CFR20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design. The survey design specified fourteen (14) soil samples for non-parametric statistical testing. 14

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS As the survey unit was classified as Class 1, sample locations were selected based on a systematic triangular grid with a random starting point. The systematic locations of the soil samples were selected using Visual Sample Plan (VSP), in accordance with LC-FS-PR-002. Input parameters included use of aerial photographs, the GPS route of the boundary of the excavation, and seventy (70) 20 by 20 grids. The systematic coordinates generated with VSP were integrated with a GPS to identify sample locations in the field. Table 5-3 lists the systematic samples collected for FSS and the corresponding GPS coordinates, based on the Wisconsin State Plane North American Datum 1983 coordinate system.

Ten percent (10%) of the FSS samples collected from open land survey units (including excavations where major sub-grade structures previously resided) will be analyzed for HTD ROC. In addition, if any sample has a SOF of 10% of the Operational DCGL or more, it must be sent for HTD ROC analysis. Only the HTD radionuclide included as ROC (Sr-90) will be analyzed in the FSS confirmatory samples. For samples with positive results for both the HTD ROC and the corresponding surrogate radionuclide (Cs-137), the HTD surrogate ratio will be derived and compared against the 95% UCL ratio (see Table 5-1). If the derived ratio from the confirmatory samples exceeds the 95% UCL ratio, then the area-specific ratio as determined by actual survey data will be used. The selection of one (1) soil sample, L1-SUB-TDS-FSGS-010-SB, from the systematic sample population met the requirement that a minimum of 10% of the samples collected for the FSS of the survey unit be analyzed for HTD ROC. The selected sample was sent off-site (GEL Laboratories) for analysis of the HTD ROC as specified in LTP Chapter 5, Section 5.1. Seven (7) of the eight (8) judgmental samples collected for continuing characterization were sent off-site for full suite ROC analysis, as explained in Section 3 of this release record. The implementation of quality control measures as referenced by LTP Chapter 5, Section 5.9 and LaCrosseSolutions LC-QA-PN-001, Final Status Survey Quality Assurance Project Plan (QAPP) (Reference 10) includes the collection of a soil sample for split sample analysis on 5% of the soil samples taken in a survey unit with the locations selected at 16

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS random. One (1) soil sample, L1-SUB-TDS-QSGS-004-SB, was designated for split sample QC analysis for the FSS of this survey unit. LTP Chapter 5, Section 5.6.4.4 and Table 5-15 specifies that for Class 1 survey units, surface scans will be performed on 100% of the surface area in the survey unit. For survey unit L1-SUB-TDS, 100% scan coverage equates to 1,185.5 m2. To encapsulate the entire area of the survey unit, a 20 by 20 grid pattern was overlaid on a map of the survey unit. The survey unit spanned through portions of thirty-eight (38) of the sixty-three (63) total grids. A map of the scan grid locations is provided in Attachment 1. For this Class 1 excavation survey unit, the Investigation Levels for area scanning and soil sample measurement results are those levels specified in LTP Chapter 5, Table 5-16, and are reproduced below in Table 5-5.

6. SURVEY IMPLEMENTATION For survey unit L1-SUB-TDS, compliance with the unrestricted release criteria was demonstrated through a combination of soil scanning with a Ludlum Model 44-10 gamma detector and the sampling of soil for isotopic analysis.

An FSS Supervisor performed a visual inspection and walk-down of the survey unit on January 4, 2018, prior to performing FSS. The purpose of the walk-down was to assess the physical condition of the survey unit, evaluate access points and travel paths, and identify potentially hazardous conditions. FSS field activities were conducted under the FSS Sample Plan, which included DQOs, survey design, detailed FSS instructions, job safety analysis, and related procedures for reference. A Field Log was used to document field activities and other information pertaining to the performance of the FSS. FSS field activities commenced on January 5, 2018. FSS field activities were projected to take ten (10) working days to complete. Daily briefings were conducted to discuss the expectations for job performance and to review safety aspects 18

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS of the job. The survey required field activities were performed during normal working hours and concluded on January 15, 2018. The fourteen (14) systematic soil sample locations were marked with flags based on GPS coordinates provided. Each soil sample consisted of approximately one (1) liter of soil. The sample media was sifted to remove stones and other media larger than one (1) centimeter in diameter. All soil samples were collected, controlled, transported, stored and transferred to the on-site laboratory using the Chain-of-Custody process from LC-FS-PR-012, Chain of Custody Protocol (Reference 11), and in accordance with LC-FS-PR-004, Sample Media Collection for Site Characterization and Final Status Survey (Reference 12), LC-FS-PR-005, Sample Media Preparation for Site Characterization and Final Status Survey (Reference 13), and LC-FS-PR-001, Sample Storage (Reference 14). A total of thirty-eight (38) scan grids, constituting a total scan coverage of 1,185.5 m2, or approximately 100% of the surface area in the survey unit, were established. Background was assessed in the survey unit using a Ludlum 2350-1 paired with a Ludlum Model 44-10 (2x 2) sodium iodide (NaI) detector. The background was established as the average of five (5) 1-minute static measurements, while maintaining the detector 6 from the soil. In survey unit L1-SUB-TDS, background ranged from 7,263 counts per minute (cpm) up to 8,899 cpm. All designated scan areas as denoted on Figure 1in Attachment 1 were scanned using a Ludlum 2350-1 paired with a Model 44-10 2x 2 NaI detector operated in the rate-meter mode and using audio response. The probe was positioned no more than 3 from the ground and was moved at a scan speed of approximately 0.5 meters per second. In accordance with RS-TD-313196-006, Ludlum Model 44-10 Detector Sensitivity (Reference 15), scan MDC was sufficient to detect residual radioactivity at the action level (adjusted surrogate DCGL of 17.31 pCi/g, which was based on the surrogate adjusted DCGL of Cs-137 while inferring Sr-90). Complete scan results are provided in Attachment 2. Ten (10) judgmental soil samples were collected during implementation of FSS. These samples were collected to investigate locations where scanning revealed higher readings and for continuing characterization as required by the LTP Chapter 5, Section 5.3.3.4. The locations of the judgmental samples are presented in Figure 2 of Attachment 1. The survey design specified that a minimum of one (1) sample (10%) was required for HTD ROC analysis. Sample L1-SUB-TDS-FSGS-010-SB was selected for HTD radionuclide analysis. Seven (7) additional samples from continuing characterization (L1-SUB-TDS-FJGS-003-SB, L1-SUB-TDS-FJGS-004-SB, L1-SUB-TDS-FJGS-005-SB, L1-SUB-TDS-FJGS-006-SB, L1-SUB-TDS-FJGS-007-SB, L1-SUB-TDS-FJGS-008-SB, and L1-SUB-TDS-FJGS-010-SB) were selected for HTD analysis of the initial full suite of radionuclides. 19

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS The survey design specified one (1) sample to be collected for QC split and duplicate analysis. The implementation of survey specific QC measures included the collection of three (3) samples (L1-SUB-TDS-QSGS-004-SB, L1-SUB-TDS-FJGS-008-SB SPLIT, and L1-SUB-TDS-FJGS-009-SB SPLIT) for split and duplicate sample analysis.

7. SURVEY RESULTS All areas identified in the FSS plan were scanned for elevated radiation levels. No elevated measurement locations were identified by surface scan. Table 7-1 provides an overview of the scan results for all scan grids (identified as A1 through G9), the 1 m2 scan areas around each sample location (identified as SP1 through SP14 and JSP2 through JSP10), and QC locations (identified with a Q). Complete scan results are provided in Attachment 2.

The Action Level was calculated using a background of 31,800 cpm and an MDCR of 1,906 cpm for a total of 33,706 cpm. The MDCR value equates to Cs-137 concentration of 9.2 pCi/g, which is equivalent to approximately 20% of the Cs-137 Base case DCGL for soil. A pre-established gross background and ASP was used during FSS because of an anticipated elevated background due to the survey units proximity to the Reactor Building. Retroactively fitting the scan data to Action Levels based on the Operational DCGL and the actual background data collected during the FSS, resulted in fourteen (14) scan measurements that would have alarmed, and in turn would have triggered the collection of investigational soil samples. As can be seen in Table 7-1 above, no investigational samples were collected. Because 100% of the soil in the survey unit was scanned and the maximum Sum-of-Fraction (SOF) of all applicable Radionuclides of Concern (ROC), either by direct measurement or by inference, is equal to 0.0552 when applying the respective Operational Derived Concentration Guideline Levels (OpDCGLS) for soil, the probability of discovering an elevated soil sample is very low, even had investigational samples been collected. The on-site laboratory analyzed the fourteen (14) soil samples taken for non-parametric statistical testing using the on-site gamma spectroscopy system. A summary of the gamma spectroscopy results for the fourteen (14) samples collected for non-parametric statistical testing is provided in Table 7-2. Gamma spectroscopy results revealed ten (10) samples above MDC for Cs-137 and one (1) sample above MDC for Co-60; there were no samples above MDC for any other ROC. The concentration for Sr-90 was inferred based on the ratio 22

Continuing characterization samples L1-SUB-TDS-FJGS-003-SB, L1-SUB-TDS-FJGS-004-SB, L1-SUB-TDS-FJGS-005-SB, L1-SUB-TDS-FJGS-006-SB, L1-SUB-TDS-FJGS-007-SB, L1-SUB-TDS-FJGS-008-SB, L1-SUB-TDS-FJGS-010-SB, and FSS sample L1-SUB-TDS-FSGS-010-SB were selected. All off-site samples were analyzed for the initial suite of radionuclides, except for sample L1-SUB-TDS-FSGS-010-SB, which was only analyzed for Sr-90. All analyses met the required MDC. Sr-90 was not detected in any of the samples sent for off-site analysis. Therefore, there was no need to re-evaluate the 95% UCL ratio of 0.502 established during continuing characterization. Gamma spectroscopy results revealed six (6) samples above MDC for Cs-137 with a maximum concentration of 0.189 pCi/g. Two (2) samples were above MDC for Co-60, and two (2) samples were above MDC for Tc-99 with maximum concentrations of 0.0816 pCi/g and 0.628 pCi/g, respectively. No samples were above MDC for any other ROC. The positive Tc-99 samples are part of the continuing characterization population. As stated in Section 3 of this release record, the IC dose is unchanged (dose fraction less than 10%). The results are provided in Table 7-4.

8. QUALITY CONTROL The on-site laboratory processed three (3) split and duplicate samples (L1-SUB-TDS-QSGS-004-SB, L1-SUB-TDS-FJGS-008-SB SPLIT, and L1-SUB-TDS-FJGS-009-SB SPLIT) using gamma spectroscopy analysis. The data was evaluated using USNRC acceptance criteria specified in Inspection Procedure No. 84750, Radioactive Waste Treatment, and Effluent and Environmental Monitoring (Reference 16). There was acceptable agreement between field split results. Refer to Attachment 4 for data and quality control analysis results.

9. INVESTIGATIONS AND RESULTS No investigations were performed during the performance or analyses of the survey.

10. REMEDIATION AND RESULTS The purpose of the excavation of the portion of survey unit L1-010-102 was to remove the Turbine Building/Turbine Building Offices and 1B Diesel Generator Building, as well as associated system lines. The purpose of the excavation was not to support removal of contaminated subsurface soil.

11. CHANGES FROM THE FINAL STATUS SURVEY PLAN There were no addendums to the FSS plan.

12. DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with LC-FS-PR-008, Final Status Survey Data Assessment (Reference 17) for completeness and consistency. Documentation was complete and legible. Surveys and the collection of samples were consistent with the DQOs and were sufficient to ensure that the survey unit was properly 28

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS designated as Class 1. The survey design had adequate power as indicated by the Retrospective Power Curve (see Attachment 6). The analytical results indicated that all samples were less than a SOF of one (1) when compared to the OpDCGLS. Additionally, the maximum activity for each ROC did not exceed 10% of their respective OpDCGLS. Although MARSSIM states that the Sign Test need not be performed in the instance that no measurements surpass the Operational DCGL, the test was conducted to demonstrate coherence to the statistical principles of the DQO process. The Sign Test was performed on the data and compared to the original assumptions of the DQOs. The evaluation of the Sign Test results clearly demonstrates that the survey unit passes the unrestricted release criteria, thus, the null hypothesis is rejected. The results of the Sign Test are presented in Attachment 3. The data assessment and review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). All data was considered valid including negative values, zeros, values reported below the MDC, and values with uncertainties that exceeded two standard deviations. The mean and median values for each ROC were well below the respective Operational DCGLs. Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power. Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs. The mean of all identified isotopes are less than the Consultation Triggers for Residential Soil Concentration depicted in Table H.1 of NUREG 1757, Vol.1, Rev. 2 (MOU Table 1). The full table is included in Attachment 5 of this release record. The data for Cs-137 is presented graphically through a frequency plot and quantile plot. All graphical presentations are provided in Attachment 6.

13. ANOMALIES No anomalies were observed during the performance or analyses of the survey.

14. CONCLUSION Survey unit L1-SUB-TDS has met the DQOs of the FSS plan. The ALARA criteria as specified in Chapter 4 of the LTP were achieved and remediation was not required.

All identified ROC were used for statistical testing to determine the adequacy of the survey unit for FSS. Evaluation of the data shows that none of the systematic ROC concentration values exceeds the OpDCGLS; therefore, in accordance with LTP Section 5.11, the survey unit meets the release criteria. 29

FSS RELEASE RECORD L1-010-102 EXCAVATION SURVEY UNIT L1-SUB-TDS The sample data passed the Sign Test. The null hypothesis was rejected. The Retrospective Power Curve showed that adequate power was achieved. The survey unit is properly classified as Class 1. The dose contribution from soil in survey unit L1-SUB-TDS is 0.3115 mrem/yr TEDE, based on the average concentration of the ROC in samples used for non-parametric statistical sampling. Survey unit L1-SUB-TDS is acceptable for unrestricted release.

K-40 was substituted as the radionuclide for split assessment because Cs-137 was only present in the comparison sample. The split assessment for L1-SUB-TDS-FJGS-009-SB & L1-SUB-TDS-FJGS-009-SB SPLIT resulted in a failure. Because the values are well below the operational DCGL no further action is necessary. 42

    ^     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. Page 31 of 44
