SUMMARY

This Final Status Survey (FSS) Release Record for survey unit L1-010-104, North LACBWR Site Enclosure (LSE) Grounds, 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 (LACBWR 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). Survey unit L1-010-104, an open land 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, 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 L1-010-104 indicate that the maximum Sum-of-Fractions (SOF), considering the concentration of all applicable Radionuclides of Concern (ROC) either by direct measurement or by inference, is equal to 0.0534 when applying the respective Operational Derived Concentration Guideline Levels (OpDCGLS) for soil. Therefore, the null hypothesis is rejected and survey unit L1-010-104 is acceptable for unrestricted release. The mean SOF when applying the respective Base Case DCGLs (DCGLS) for soil is 0.011. This SOF equates to a dose for the survey unit of 0.2624 mrem/yr.

2. SURVEY UNIT DESCRIPTION Survey unit L1-010-104 is an impacted Class 1 open land survey unit. The surface area of the survey unit is 2,387 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 L1-010-104. 5

3. CLASSIFICATION BASIS Survey unit L1-010-104 was identified in the Historical Site Assessment (HSA) (Reference

5) as a Class 1 survey unit. The following summarizes the results of the characterization survey for survey unit L1-010-104.

The initial site characterization surveys performed by EnergySolutions were conducted between October 9, 2014, and August 6, 2015. In total, one (1) surface soil sample, fourteen (14) subsurface soil samples, and ten (10) asphalt samples were collected in survey units L1-010-104. All samples were analyzed by the on-site gamma spectroscopy system. For the surface soil sample, no ROC was detected. For subsurface soil samples, Cs-137 was detected at concentrations above MDC in three (3) of the samples, at a maximum concentration of 5.10E-02 pCi/g. Co-60 was not detected at concentrations above MDC in any of the subsurface samples. For asphalt samples, Cs-137 was detected at concentrations above MDC in one (1) of the samples, at a maximum concentration of 5.70E-02 pCi/g. Co-60 was not detected at concentrations above MDC in any of the asphalt samples. A summary of the analyses for the surface soil, subsurface soil, and asphalt samples taken during site characterization are presented in Table 3-1. Two (2) subsurface soil and two (2) asphalt samples from characterization were sent to Test America Laboratories for off-site analysis. A summary of the off-site analyses is presented in Table 3-2. 6

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS 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 Table 4 of TSD RS-TD-313196-004, LACBWR Soil DCGL, Basement Concrete DCGL, and Buried Pipe DCGL (Reference 6) for soil. If the IC dose calculated is less than the IC dose assigned for DCGL adjustment, then no further action will 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 hard-to-detect (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 will be documented in the release record for the survey unit. A Radiological Assessment (RA) in survey unit L1-010-104 was performed in May of 2019. Twenty-two (22) soil samples were collected and analyzed by the on-site gamma spectroscopy system. The average SOF of the sample set was 0.022, with a standard deviation 0.0103. The RA data was used to design the FSS. Five samples from the RA were sent off-site for full suite radionuclide analysis. An assessment of the results of continuing characterization confirmed that the IC dose is unchanged. The maximum calculated IC dose was 0.0837 mrem/yr, which is below the 2.5 mrem/yr limit provided in the LTP for DCGL adjustment. A summary of the off-site analytical results for continuing characterization (RA) samples is provided in Table 3-3 below. Only Cs-137 and Co-60 were detected at concentrations greater than MDC in the off-site RA samples.

Based upon review of the historical information, the results of the characterization survey data and RA data, and completion of a final Survey Unit Classification Worksheet, the correct final classification of survey unit L1-010-104 was determined to be Class 1.

4. DATA QUALITY OBJECTIVES (DQO)

FSS planning and design relies on a properly executed 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, utilized in accordance with MARSSIM, is described in the LACBWR LTP. 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 10

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS 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 is to demonstrate that the level of residual radioactivity in survey unit L1-010-104 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). EnergySolutions 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 radionuclides. The results of surface and subsurface soil characterization in the impacted area surrounding LACBWR indicate that there is minimal residual radioactivity in soil. IC were determined 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 IC 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. The LTP, Section 6.14.1 discusses the process used to derive the ROC for the decommissioning of LACBWR, including the elimination of IC 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. 11

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS 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. The 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 (i.e., 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 (e.g., calculation of surrogate DCGLs, investigation levels). Details of the Operational DCGLs derived for each dose component and the basis for the applied a priori dose fractions are provided in LC-FS-TSD-002, Operational Derived Concentration Guideline Levels for Final Status Survey (Reference 9). Multiple ROCs are known to be present at LACBWR. 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. In Class 1 land survey units, 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 (e.g., basements, soils, buried pipe, above-ground structures, and 12

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS groundwater) for the end-state. 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, Section 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 LTP, Section 6.16.1 are reproduced in Table 4-2. The IC 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.

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the Operational DCGL. 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 calculated results. The actual reported value was used as the recorded FSS result for measurement and/or sample values that are less than MDC. Negative values were 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 L1-010-104 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 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: 14

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS design and implementation. This approach was conservative since it included background Cs-137 as part of the sample set. The number of soil samples for FSS was determined in accordance with procedure LC-FS-PR-002. The relative shift (/) for the survey unit data set is defined as shift (), which is the Upper Boundary of the Gray Region (UBGR), or the DCGL (SOF of 1), minus the Lower Bound of the Gray Region (LBGR) (mean SOF), divided by sigma (), which is the standard deviation of the data set used for survey design. The optimal value for / should range between one (1) and three (3). The largest value the / can have is three (3). If the calculated value of / exceeds three (3), an adjusted value of three (3) will be used for /. The / for survey unit L1-010-104, based on the data for surface soil samples collected during the RA of survey unit L1-010-104, was calculated as follows: Equation 3

     /     =      (1 - 0.022) / 0.0103    =       95 As the calculated relative shift was greater than three (3), a value of three (3) was used as the adjusted /. Both the Type I error (i.e.,  value) and the Type II error (i.e.,  value) was set at 0.05. The sample size from Table 5.5 of MARSSIM that equates to the Type I and Type II error of 0.05 for use with the Sign Test is an N value of fourteen (14).

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. 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 and the systematic sampling tool set with a predetermined number (14) of samples. 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.

The number of judgmental samples actually obtained was four (4). In addition, one (1) investigational sample was collected. The total number of samples collected for the FSS of survey unit L1-010-104 was nineteen (19).

Ten percent (10%) of the FSS samples collected from open land survey units will be analyzed for HTD ROC. Only the HTD radionuclide included as ROC (Sr-90) will be analyzed in the FSS confirmatory samples. In addition, if any sample has a SOF of 10% of the Operational DCGL or more, it must be sent for HTD ROC analysis. For samples with positive results for both the HTD ROC and the corresponding surrogate radionuclide (Cs-137), the HTD surrogate ratio will 17

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS 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 two (2) soil samples (L1-010-104-FSGS-006-SS and L1-010-104-FJGS-016-SS) met the requirement that a minimum of 10% of the samples collected for the FSS of survey unit L1-010-104 be analyzed for HTD ROC. The implementation of quality control measures as referenced by LTP, 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 random. One (1) soil sample, L1-010-104-FQGS-003-SS, was designated for split sample QC analysis for the FSS of this survey unit. The LTP, Section 5.6.4.4 and Table 5-15 specifies that for Class 1 open land survey units, surface scans will be performed on 100% of the surface area in the survey unit. For survey unit L1-010-104, 100% scan coverage equates to 2,387 m2. One hundred and sixteen (116) scan lanes were established. For this Class 1 open land survey unit, the Investigation Levels for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-16, and are reproduced below in Table 5-5.

6. SURVEY IMPLEMENTATION For survey unit L1-010-104, 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 August 20, 2019, 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. At the time of survey, the survey unit was dry and nothing was deemed to be a considerable constraint for the collection of samples and scan measurements. 19

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS 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. FSS field activities were projected to take four (4) working days to complete. Daily briefings were conducted to discuss the expectations for job performance and to review safety aspects of the job. A Field Log was used to document field activities and other information pertaining to the performance of the FSS. FSS field activities commenced on August 21, 2019, and were concluded on August 23, 2019. A total of one hundred and sixteen (116) different scan lanes, constituting an areal coverage of 2,387 m2, were scanned using a Ludlum 2350-1 paired with a Ludlum Model 44-10 (2 x 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 L1-010-104, background ranged from 3,935 cpm up to 7,368 cpm. All designated scan areas were scanned using a Ludlum 2350-1 paired with a Model 44-10 2 x 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 11), 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. The fourteen (14) systematic sample locations were marked with flags based on GPS coordinates provided. Each soil sample consisted of approximately one (1) liter of soil. The soil 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 12), and in accordance with LC-FS-PR-004, Sample Media Collection for Site Characterization and Final Status Survey (Reference 13), LC-FS-PR-005, Sample Media Preparation for Site Characterization and Final Status Survey (Reference 14), and LC-FS-PR-001, Sample Storage (Reference 15). The LTP, Section 5.7.1.5.2 states that in Class 1 open land survey units, a subsurface soil sample will be taken at 10% of the systematic surface soil sample locations in the survey unit with the location(s) selected at random. In addition, if during the performance of FSS, the analysis of a surface soil sample, or the results of a surface gamma scan indicates the potential presence of residual radioactivity at a concentration of 75% of the soil Operational DCGL, then biased subsurface soil sample(s) will be taken to the appropriate depth within the area of concern as part of the investigation. Two (2) judgmental subsurface soil samples 20

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS (L1-010-104-FSGS-009-SB and L1-010-104-FSGS-014-SB) were collected to satisfy the 10% requirement from the LTP. Subsurface soil samples were collected using a hand auger. The survey design specified that a minimum of one (1) sample was required for HTD ROC analysis. In total, two (2) samples (L1-010-104-FSGS-006-SS and L1-010-104-FJGS-016-SS) were selected for HTD radionuclide analysis. In accordance with the sample plan, at least one (1) judgmental sample is required from the survey unit. The number of judgmental samples actually obtained was four (4), and one (1) investigational sample was obtained due to a scan alarm. One of the judgmental samples was collected due to higher readings in an area around the building and another was collected at a previous concrete core site. The implementation of survey specific QC measures included the collection of two (2) samples (L1-010-104-FQGS-003-SS, and L1-010-104-FSGS-003-SS SPLIT) for split and duplicate sample analysis.

7. SURVEY RESULTS All areas identified in the FSS sample plan were scanned for elevated activity levels. A total of one (1) alarm was verified during scanning of lanes. One (1) investigational sample was collected in response to the scan alarm. Table 7-1 provides an overview of the scan results for all scan lanes (identified as 01 through 116), the 1 m2 scan areas around each sample location before and after sample collection (identified with SP), and QC locations (identified with a QC). Complete scan results are provided in Attachment 2.

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS

8. QUALITY CONTROL The on-site laboratory processed two (2) split and duplicate samples (L1-010-104-FQGS-003-SS, and L1-010-104-FSGS-003-SS 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). Cs-137 was not detected in any sample; as such, K-40 was substituted for the comparison. There was acceptable agreement between field split and duplicate results. Refer to Attachment 4 for data and quality control analysis results.

9. INVESTIGATIONS AND RESULTS One (1) soil sample was collected to investigate a scan alarm in scan lane 90. The sample (L1-010-104-FJGS-015-SS) was analyzed using the on-site gamma spectroscopy system.

Gamma spectroscopy results revealed that no ROC were positively identified. The SOF for the investigational sample, when compared to the Operational DCGL, is 0.06955.

10. REMEDIATION AND RESULTS No radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS. Chapter 4 of the LTP determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in soil was ALARA.

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 designated as Class 1. The survey design had adequate power as indicated by the Retrospective Power Curve (see Attachment 6). The measurement results indicated that all samples were less than a SOF of one (1) when compared to the OpDCGLS. 30

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS 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 preliminary data 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 is 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 L1-010-104 has met the DQOs of the FSS plan. The ALARA criteria as specified in Chapter 4 of the LTP were achieved. The Elevated Measurement Comparison for soils was not applicable 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. 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. 31

FSS RELEASE RECORD - REVISION 1 SURVEY UNIT L1-010-104 ~ NORTH LSE GROUNDS LACROSSESOLUTIONS The dose contribution from soil in survey unit L1-010-104 is 0.2624 mrem/yr TEDE, based on the average concentration of the ROC in samples used for non-parametric statistical sampling. Survey unit L1-010-104 is acceptable for unrestricted release.

   ^     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.
