1. EXECUTIVE

SUMMARY

This Final Status Survey (FSS) Release Record for survey unit 10301, West Training Area, has been generated for the Zion Station Restoration Project (ZSRP) in accordance with ZionSolutions procedure ZS-LT-300-001-005, Final Status Survey Data Reporting (Reference 1) and satisfies the requirements of Section 5.11 of the Zion Station Restoration Project License Termination Plan (LTP) (Reference 2).

A Final Status Survey (FSS) package (L3-10301A-F) was developed in accordance with ZionSolutions procedure ZS-LT-300-001-001, Final Status Survey Package Development (Reference 3), the ZSRP LTP, and with guidance from NUREG-1575, Revision 1, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)

(Reference 4).

This open land survey unit has a MARSSIM classification of 3. 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) randomly located surface soil samples were acquired from the survey unit. In addition, surface scanning was performed on 5% of the total surface area in the survey unit. As an investigation of the manhole present in the survey unit, one (1) gamma measurement was collected with the In Situ Object Counting System (ISOCS) and two (2) surface soil samples were collected. Additionally, one (1) judgmental surface soil sample was collected to investigate the soil nearest the roadway on the north border of the survey unit. The analytical results for all soil samples taken in survey unit 10301 indicate that the Sum-of-Fraction (SOF) for each sample, considering the concentration of all applicable Radionuclides of Concern (ROC), either by direct measurement or by inference, is less than 0.0825 when applying the respective Operational Derived Concentration Guideline Levels (OpDCGL). Therefore, the null hypothesis is rejected and survey unit 10301 is acceptable for unrestricted release.

2. SURVEY UNIT DESCRIPTION West Training Area, survey unit 10301, is an impacted Class 3 open land survey unit. It is bounded by Shiloh Boulevard to the north. The area of the survey unit is 55,942 m2.

The topography of the survey unit is mainly flat with some small dips and depressions.

The soil is loam. The terrain consists of thick underbrush, small and large trees, and wetlands. Solid physical items such as rocks, concrete jersey barriers, a 6x9 concrete pad, a make-shift wooden bridge, a manhole, a steel cable, telephone poles, and power lines are present in the area.

3. CLASSIFICATION BASIS Survey unit 10301 was classified in accordance with ZionSolutions procedure ZS-LT-300-001-002, Survey Unit Classification (Reference 5).

Impacted Class 3 open land survey unit 10301 was originally identified as non-impacted by the Historical Site Assessment (HSA) (Reference 6). Due to the fact that the area was once the location of the Training Building which housed a Westinghouse Nuclear Training Reactor as well as other structures that were impacted by site operations, the survey unit was reclassified as an impacted Class 3 survey unit. The HSA does not cite any processes and/or incidents involving the use and/or handling of radioactive material in this open land survey unit and an inspection of the survey unit did not identify any visual indications that there are any subsurface burial sites present in this area.

Characterization surveys were performed in this survey unit from August 1, 2013, through August 12, 2013. The original survey design for this survey unit called for fifty-six (56) static measurements using the ISOCS with locations selected at random. Of the fifty-six (56) locations selected at random, twenty-one (21) were deemed as inaccessible or obstructed. Eleven (11) additional ISOCS measurements were taken as investigations prompted by observations of potential burial locations based on visual inspection. All

[5]

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 eleven (11) investigation measurements were taken with the ISOCS elevated to one-meter, reducing the effective FOV to three (3) square meters. Cs-137 was the only plant-derived gamma emitting radionuclide detected by the ISOCS at a concentration greater than the instrument MDC. Cs-137 was positively detected in seven (7) of the forty-six (46) ISOCS measurements taken. The average observed concentration of Cs-137 was 0.18 pCi/g with a maximum observed concentration of 0.25 pCi/g.

Thirteen (13) random locations were selected for survey by gamma scan and surface soil sampling. Nine-thousand one-hundred one (9,101) square meters or approximately 16% of the total surface area in the survey unit was scanned using a Ludlum Model 2350-1 and a Model 44-10 NaI detector. The average observed background in the survey unit was 4,914 cpm. The average observed scan measurement was 5,433 cpm with a maximum observed measurement of 9,499 cpm. Twenty-three (23) scan alarms were observed in this survey unit with the scan alarm set-point set at the MDCR plus background. The area was investigated by additional scans and eleven (11) investigative surface soil samples were acquired at the locations were the scan alarms were observed.

Twenty-four (24) surface soil samples and two (2) QC split sample were acquired and analyzed by the on-site gamma spectroscopy system. Cs-137 was identified at concentrations greater than the MDC of the instrument in twelve (12) of the twenty-four (24) surface soil samples. No other potential plant-derived radionuclides were positively identified. The average Cs-137 concentration observed in the analysis of the surface soil samples was 0.17 pCi/g with a maximum observed concentration of 0.39 pCi/g.

The locations of scan areas and surface soil samples taken during characterization in survey unit 10301 are illustrated on Figure 2 in Attachment 1. A summary of the analyses results for the surface soil samples taken during site characterization are presented in Table 1.

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 A Radiological Engineer (RE) performed a visual inspection and walk-down of the survey unit on 04/26/2016 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. A final classification assessment was performed in accordance with procedure ZS-LT-300-001-002, Survey Unit Classification as part of the survey design for FSS.

Based upon completion of Survey Unit Classification Basis for final classification, which included a review of the historical information, the results of the Characterization Survey data and, completion of a final Survey Unit Classification Worksheet, it was concluded that there was a low probability for the presence of residual radioactivity in soils in concentrations greater than 50% of the Operational DCGLs, justifying a final survey unit classification of Class 3.

4. DATA QUALITY OBJECTIVES (DQO)

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 ZSRP LTP in accordance with MARSSIM. The appropriate design for a given survey will be 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 is to demonstrate that the level of residual radioactivity in survey unit 10301 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).

ZionSolutions TSD 11-001, Potential Radionuclides of Concern during the Decommissioning of Zion Station (Reference 7) established the basis for an initial suite

[7]

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 of potential ROC for the decommissioning of the Zion Nuclear Power Station (ZNPS).

LTP Chapter 2 provides detailed characterization data that describes the results of surveys taken of soils. 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 ZNPS indicate that there is minimal residual radioactivity in soil. Consequently, due to the absence of any significant source term in soil, the suite of ROC and radionuclide mixture derived for non-activated concrete was considered as a reasonably conservative mixture to apply to soils for FSS planning and implementation.

LTP Chapter 6, section 6.5.2 discusses the process used to derive the ROC for the decommissioning of ZNPS, including the elimination of insignificant dose contributors (IC) from the initial suite. Based upon the analysis of the mixture, it was determined that Co-60, Ni-63, Sr-90, Cs-134 and Cs-137 accounted for 99.5% of all dose in the non-activated contaminated concrete mixes.

Table 2 presents the ROC for the decommissioning of soils at ZNPS and the normalized mixture fractions based on the radionuclide mixture.

(2) Does not include dose significant radionuclides for activated concrete (H-3, Eu-152, Eu-154).

A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity. This is done through the development of DCGLs.

The DCGLs represent average levels of radioactivity above background levels and are presented in terms of surface or mass activity concentrations. Chapter 6 of the LTP describes in detail the modeling used to develop the DCGLs for soils.

[8]

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 Surface soil is defined as soil residing in the first 0.15 m layer of soil. A subsurface soil category, which is defined as a layer of soil beginning at the surface but extending to a depth of 1 m is also assessed to allow for flexibility in compliance demonstration if contamination deeper than 0.15 m is encountered. Site-specific DCGLs for soil were calculated for both the 0.15 m and 1 m thicknesses. 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.

ZionSolutions TSD 14-011, Soil Area Factors (Reference 8) and LTP Chapter 6, section 6.8 provides the exposure scenarios and modeling parameters that were used to calculate the site-specific DCGLs for soils (referred to as Base Case Soil DCGLs in this Release Record).

At ZNPS, compliance is demonstrated through the summation of dose from four distinct source terms for the end-state (basements, soils, buried pipe and groundwater). Basements are comprised of the summation of four structural source terms (surfaces, embedded pipe, penetrations and fill). When applied to soil, the DCGLs are expressed in units of activity per unit of mass (pCi/g). The unity rule is applied when there is more than one ROC.

The measurement results for each singular ROC present in the mixture are compared against their respective DCGL to derive a dose fraction.

The surface and subsurface soil Base Case DCGLs for the unrestricted release of open land survey units are provided in Table 3 and Table 4, respectively. The IC dose percentage of 10% was used to adjust the DCGLs in soils to account for the dose from the eliminated IC radionuclides.

Co-60 3.44 Cs-134 4.44 Cs-137 7.75 Ni-63 763.02 Sr-90 1.66 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 per year to an Average Member of the Critical Group (AMCG). To ensure that the summation of dose from each source term is 25 mrem/year 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/year 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 applied a priori dose fractions are provided in ZionSolutions TSD 17-004, Operational Derived Concentration Guideline Levels for Final Status Survey (Reference 9).

The Operational DCGLs for the FSS of surface and subsurface soils are presented in Table 5 and Table 6, respectively.

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 recorded 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. 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 percent 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 ZS-LT-300-001-001 Final Status Survey Package Development. The FSS plan uses an integrated sample design that combines scanning surveys and sampling which can be either random or judgmental.

The DQO process determined that Co-60, Ni-63, Sr-90, Cs-134 and Cs-137 would be the ROC in survey unit 10301. During FSS, concentrations for Hard-to-Detect (HTD) ROC Ni-63 and Sr-90 are inferred using a surrogate approach. Cs-137 is the principle surrogate radionuclide for Sr-90 and Co-60 is the principle surrogate radionuclide for Ni-63. The mean, maximum and 95% Upper Confidence Level (UCL) of the surrogate ratios for concrete core samples taken in the Auxiliary Building basement were calculated in ZionSolutions TSD 14-019, Radionuclides of Concern for Soil and Basement Fill Model Source Terms (Reference 10) and are presented in Table 7. The maximum ratios will be used in the surrogate calculations during FSS unless area specific ratios are determined by continuing characterization.

The equation for calculating a surrogate DCGL is as follows:

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 Using the Operational DCGLs presented in Table 5 and the maximum ratios from Table 7, the following surrogate calculations were performed:

The action level for investigation in a Class 3 open land survey unit is 50% of the Operational DCGL. The surrogate DCGL for Co-60 while inferring Ni-63 is 0.898 pCi/g, and the surrogate DCGL for Cs-137 while inferring Sr-90 is 3.622 pCi/g. Using the normalized mixture for gamma emitting ROC from Table 2, the surrogate adjusted gamma DCGL is then calculated as follows:

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.

The Elevated Measurement Comparison (EMC) did not apply to this survey unit since it is a Class 3 survey unit and discrete, elevated areas of contamination were not expected.

The number of soil samples for FSS was determined in accordance with procedure ZS-LT-300-001-001 Final Status Survey Package Development. 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) (SOF of 0.5), divided by sigma (), which is the standard deviation of the data set used for survey design. The optimal value for / should range between 1 and 3. The largest value the / can have is 3. If the / exceeds 3, then the value of 3 will be used for /. The / for survey unit 10301, based on characterization data for Cs-137, was calculated as follows:

Equation 4

/ = 0.5/0.03 = 16.67 As the calculated relative shift (16.67) was greater than 3, then a value of 3 was used as the adjusted /. Both the Type I error, or value and the Type II error, or 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 14.

A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission

[14]

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 (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) surface soil samples for non-parametric statistical testing.

As the survey unit was classified as Class 3, systematic sample locations were selected at random. The random locations of the systematic surface soil samples were selected using Visual Sample Plan (VSP), in accordance with ZS-LT-300-001-001. Input parameters included use of Bing or Google Maps aerial photographs and the random sampling tool set with a predetermined number (14) of sample points. These coordinates were integrated with a GPS to locate sample locations in the field. Sample measurement locations for the surface soil samples taken for systematic design are listed with the GPS coordinates in Table 9.

ZSRP LTP Chapter 5, section 5.1 states that soil samples will be collected during FSS to confirm the HTD to surrogate radionuclide ratios (Table 7). Ten percent (10%) of the FSS samples collected from open land survey units will be analyzed for HTD ROC. Only HTD radionuclides included as ROC (Ni-63 and Sr-90 for soils) will be analyzed in the FSS confirmatory samples. For soil samples with positive results for both a HTD ROC and the corresponding surrogate radionuclide (Cs-137 or Co-60), the HTD surrogate ratio will be derived and compared against the maximum ratio (see Table 7). If the derived ratio from the confirmatory samples exceeds the maximum ratios (see Table 7), then the area-specific ratios as determined by actual survey data will be used in lieu of the maximum ratios.

The selection of two (2) soil sample met the requirement that 10% of the samples collected for the FSS of survey unit 10301 be analyzed for HTD ROC. Sample numbers L3-10301A-FRGS-003-SS-A and L3-10301A-FRGS-017-SS-A were selected based on exhibiting the highest concentration of Cs-137. Each selected sample was sent off-site (Eberline Analytical) for analysis of the HTD ROC as specified in LTP Chapter 5, section 5.1.

The implementation of quality control measures as referenced by LTP Chapter 5, section 5.9 and ZionSolutions ZS-LT-01, Quality Assurance Project Plan (for Characterization and FSS) (QAPP) (Reference 11) includes the collection of a soil sample for split

[16]

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 sample analysis on 5% of the soil samples taken in a survey unit with the locations selected at random. One (1) surface soil sample, L3-10301A-FQGS-010-SS was selected randomly for split sample analysis for the FSS of this survey unit.

LTP Chapter 5, section 5.6.4.4 and Table 5-24 specifies that for Class 3 survey units, judgmental (biased) surface scans will be performed on areas with the greatest potential of contamination. For open land areas, this may include surface drainage areas and collection points. The fraction of scanning coverage required for survey unit 10301 was determined during the DQO process with the total amount and location(s) based on the likelihood of finding elevated activity during FSS. Based on the HSA, the results of the characterization survey, and the operational use of this survey unit, fourteen (14) different scan areas representing 2,800 m2, or approximately 5% of the survey unit, of surface area was chosen at random. A map of the scan grid locations are provided in Figure 3.

For this Class 3 open land survey unit, the Investigation Levels for area scanning and soil sample measurement results are those levels specified in LTP Chapter 5, Table 5-25 and are reproduced below in Table 11.

6. SURVEY IMPLEMENTATION For survey unit 10301, compliance with the unrestricted release criteria was demonstrated through a combination of surface scanning with a Ludlum Model 44-10 gamma detector and the sampling of surface soil for isotopic analysis. In accordance with the LTP Chapter 5, section 5.7.1.6.2, no subsurface soil sample(s) will be taken as part of the survey design in Class 3 open land survey units. However, 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 subsurface Operational DCGL, then a biased subsurface soil sample(s) would have been taken to the appropriate depth within the area of concern as part of the investigation. This threshold

[18]

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 was not encountered during the FSS of survey unit 10301. Consequently, no subsurface soil samples were collected during FSS.

In addition, LTP Chapter 5, section 5.1 states that if levels of residual gamma radioactivity in an individual soil sample exceed a SOF of 0.1, then the sample(s) will be analyzed for HTD ROC. This threshold was not encountered during the FSS of survey unit 10301.

FSS field activities were conducted under FSS Sample Plan L3-10301A-F. FSS Sample Plan L3-10301A-F included DQOs, survey design, detailed FSS instructions, job safety analysis, and related procedures for reference. A Field Log (ZS-LT-300-001-001 Attachment 14) was used to document field activities and other information pertaining to the performance of the FSS.

FSS field activities were projected to take eight (8) working days to complete. Daily briefings were conducted to discuss the expectations for job performance and to review safety aspects of the job. The survey required field activities were performed during normal working hours starting on April 27, 2016 and concluding on June 14, 2016.

The fourteen (14) systematic surface soil sample locations were marked with flags based on GPS coordinates provided by VSP. Around each surface soil sample location, a 200 m2 scan area was marked out. A total of fourteen (14) different scan areas were established, constituting an areal scan coverage of 2,800 m2, or approximately 5% of the surface area in survey unit 10301. Background was assessed in the survey unit and it was determined that, using an Ludlum 2350-1 paired with a Model 44-10 (2x 2) sodium iodide (NaI) detector, background ranged from 2,569 counts per minute (cpm) up to 6,782 cpm.

All designated scan areas as denoted on Figure 3 in 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 as close to the ground as possible and was moved at a scan speed of approximately 0.25 meters per second. In accordance with ZionSolutions TSD 11-004, Ludlum Model 44-10 Detector Sensitivity (Reference 12), scan MDC was sufficient to detect residual radioactivity at the action level (adjusted gross gamma DCGL of 1.747 pCi/g, which was based on 50% of the normalized surrogate adjusted Operational DCGLs for gamma emitting ROC). Complete scan results are provided in Attachment 2.

In accordance with FSS design, fourteen (14) surface soil samples were collected at random locations for the systematic sample population. As an investigation of the manhole present in the survey unit, one (1) gamma measurement was collected with the In Situ Object Counting System (ISOCS) and two (2) surface soil samples were collected.

Additionally, one (1) judgmental surface soil sample was collected to investigate the soil

[19]

FSS RELEASE RECORD WEST TRAINING AREA SURVEY UNIT 10301 nearest the roadway on the north border of the survey unit. The addition of the systematic, judgmental, and investigational samples results in a total of seventeen (17) surface soil samples collected for the FSS of this survey unit. Each surface soil sample consisted of 1 liter of soil. The sample media was sifted to remove stones and other media larger than 1 centimeter in diameter. All collected soil samples were controlled, transported, stored, and transferred to the on-site laboratory using Chain-of-Custody (CoC) process from ZionSolutions procedure ZS-LT-100-001-004, Sample Media Preparation (Reference 13).

Two (2) samples (L3-10301A-FRGS-003-SS-A and L3-10301A-FIGS-017-SS-A) were selected for HTD radionuclide analysis.

The implementation of survey specific QC measures included the collection of one (1) sample (L3-10301A-FQGS-010-SS) for split sample analysis.

7. SURVEY RESULTS The scan areas identified in the FSS plan were scanned for elevated radiation levels. No elevated measurement locations were identified by surface scan. Table 13 provides an overview of the scan results. Complete scan results are provided in Attachment 2.

A summary of the fourteen (14) samples collected for non-parametric statistical testing results is provided in Table 14. Gamma spectroscopy results (summarized in Table 14) revealed nine (9) samples above MDC for Cs-137 and no samples above MDC for Co-60 or Cs-134. The concentration for Ni-63 and Sr-90 are inferred based on the maximum ratios as specified in Table 7. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels lower than the concentrations of Cs-137 expected to be found in off-site soil at within the vicinity of the ZNPS as presented in ZionSolutions TSD 13-004, Examination of Cs-137 Global Fallout in Soils at Zion Station (Reference 14).

The 2 samples, L3-10301A-FIGS-017-SS and L3-10301A-FIGS-017-SS, were analyzed using the on-site gamma spectroscopy system. Gamma spectroscopy results revealed both samples above MDC for Cs-137 and no samples above MDC for Co-60 or Cs-134. Additionally, two (2) qualitative LaBr Inspector 1000 gamma measurements and one (1) ISOCS gamma measurement were collected at the location of the discovered manhole. The Inspector 1000 results revealed a positive identification of Cs-137 for both measurements. The gamma spectroscopy results for the ISOCS measurement revealed no detection of gamma-emitting ROC at concentrations greater than MDC.

10. REMEDIATION AND RESULTS Historically, 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 ZSRP 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 ZionSolutions procedure ZS-LT-300-001-004, Final Status Survey Data Assessment (Reference 16) for completeness and consistency. Documentation was complete and legible. Surveys and sample collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 3. The sampling design had adequate power as indicated by the Retrospective Power Curve.

The analytical results of all samples were less than a SOF of one. Additionally, the maximum activity for each ROC did not exceed 10% of their respective Operational DCGL for surface soils.

Although MARSSIM states that the Sign Test need not be performed in the instance that no measurements surpass the 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 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 greater than 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 data for Co-60 and Cs-137 is represented graphically through a frequency plot and a quantile plot. All graphical representations are provided in Attachment 6.

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

14. CONCLUSION Survey unit 10301 has met the DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved. The EMC 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 ROC concentration values exceeds the Operational DCGL or any investigational levels; therefore, in accordance with the LTP Section 5.10, the survey unit meets the release criterion.

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 3.

The dose contribution from soil in survey unit 10301 is 0.2439 mrem/yr TEDE, based on the average concentration of the ROC in samples used for non-parametric statistical sampling.

Survey unit 10301 is acceptable for unrestricted release.
