1. EXECUTIVE

SUMMARY

Final Status Survey (FSS) was performed on this survey unit in March of 2019. Following the completion of this FSS, a concrete foundation structure was found in the survey unit that did not meet the requirement that all remaining structures be below 588 grade. Excavations were performed to remove this concrete. Because the geologic features of the survey unit significantly changed during the excavation, the FSS was reperformed following the completion of this work. This release record addresses the results of the reperformance of FSS. This FSS Release Record for Survey Unit 12201E, North Protected Area Yard, 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 FSS package (L1-12201E-F Plan #2) was developed in accordance with ZionSolutions procedure ZS-LT-300-001-001, Final Status Survey Package Development (Reference 3), the ZSRP LTP, and 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 1. The 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. Eighteen (18) systematic surface soil samples were acquired from the survey unit. In addition, surface scanning was performed on 100% of the total surface area in the survey unit. One (1) latch value reading was recorded in in an area with elevated activity identified during the scan. An investigation soil sample taken showed no activity above MDA for the ROC. The analytical results for the systematic soil samples taken in Survey Unit 12201E indicate that the Sum-of-Fraction (SOF) for each sample, when compared to the Operational Derived Concentration Guideline Levels (OpDCGL), was less than 1.0, with a maximum Operational SOF (OpSOF) of 0.039. The mean OpSOF for the systematic samples was 0.013. The mean SOF (BcSOF), when the analytical results were compared to the Base Case DCGLs (BcDCGL), was 0.003, which results in a dose assigned to the survey unit of 0.085 mrem/yr. Therefore, the null hypothesis is rejected and survey unit 12201E is acceptable for unrestricted release.

2. SURVEY UNIT DESCRIPTION Survey Unit 12201E, North Protected Area Yard, is a Class 1 open land survey unit and is 1,902 m2 in size. It is bounded on the west by survey unit 12201D, the south by 12205A, the east by 12101, 12102 and 12103; and the north by 10202D.

[7]

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E The boundary of the survey unit was defined using a Global Positioning System (GPS) based on the Illinois State Plane System North American Datum (NAD) 1983 East. The reference coordinates associated with the sample locations in this survey unit are presented in Table 8.

3. CLASSIFICATION BASIS Survey unit 12201E was classified in accordance with ZionSolutions procedure ZS-LT-300-001-002, Survey Unit Classification (Reference 5).

The area encompassing this survey unit is located within Survey Unit 10102 and the north portions of Survey Units 10103 and 10104 as identified in Figure 3 of the Zion Station Historical Site Assessment (HSA) (Reference 6). The Zion Station Restoration Project License Termination Plan (LTP) subsequently designated these areas as Survey Unit 12201, a Class 2 open land survey unit, and described it as the North Restricted Area Yard in Table 2-30 of the ZSRP LTP. On July 15, 2016, due to changing radiological and operational conditions brought about by site decommissioning activities inside or adjacent to this area, Survey Unit 12201 was reclassified as a Class 1, and divided into 5 survey units: 12201A, 12201B, 12201C, 12201D and 12201E. Figure 1 below shows the boundaries of the resulting Class 1 survey units. Figure 1 - The The Five Class 1 Open Land Survey Units Created from the Original Class 2 Survey Unit 12201 A Final Status Survey of 12201E was completed in March of 2019 as a Class 1 survey unit. This classification remains applicable to this survey design. [8]

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E A Radiological Engineer (RE)/Characterization/License Termination (C/LT) Supervisor performed a visual inspection and walk-down of the survey unit on 06/16/2022 prior to performing this 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. The assessment confirmed that Survey Unit 12201E was correctly classified as Class 1.

4. DATA QUALITY OBJECTIVES (DQO)

FSS 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 LTP in accordance with MARSSIM. The appropriate design for a given survey is developed using the DQO process as outlined in Appendix D of MARSSIM. 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 12201E does 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 Technical Support Document (TSD) 11-001, Potential Radionuclides of Concern during the Decommissioning of Zion Station (Reference 7), written in 2012, established the basis for an initial suite of potential ROC for the decommissioning of the Zion Nuclear Power Station (ZNPS). ZionSolutions TSD 14-019, Radionuclides of Concern for Soil and Basement Fill Model Source Terms (Reference 8), completed in February 2017, was written to refine the initial selection of ROC for decommissioning at ZSRP. The list of ROC was evaluated using Containment Building(s) and Auxiliary Building concrete core analysis data to evaluate the dose significance of each radionuclide in the end state model. Section 4.4 of the TSD evaluated the results of the characterization data of surveys taken of soils. The following conclusion was reached: The results of surface and subsurface soil characterization in the impacted area surrounding Zion [9]

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E indicate that there is minimal residual radioactivity in soil. Essentially all of the soil results were reported as non-detectable. Other than Cs-137 at very low levels, and Co-60 at a concentration of 0.24 pCi/g in one sample, the results for all radionuclides were less than MDC. Therefore, the direct determination of radionuclide mixture fractions for initial suite radionuclides in soil is not technically feasible due to the MDC biasing issues discussed above. Based on a generalized assumption that the contaminated water that caused concrete contamination would be similar to the source of soil contamination, the ROC and radionuclide mixture derived for the Auxiliary Building concrete was considered to be reasonably representative of soils for FSS planning and implementation. The ROC for surface soils are listed in Table 1 below (From Table 5-2 of the LTP): Table 1 - Dose Significant Radionuclides and Mixture Auxiliary Building Radionuclide  % of Total Activity (normalized)(1)(2) Co-60 0.92% Ni-63 23.71% Sr-90 0.05% Cs-134 0.01% Cs-137 75.32% (1) Based on maximum percent of total activity from Table 20 of TSD 14-019, normalized to one for the dose significant radionuclides (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. Surface soil is defined as soil residing in the first 0.15 m (6 inches) 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 9) 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 BcDCGL in this Release Record). [10]

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E 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 BcDCGLs for the unrestricted release of open land survey units are listed in Tables 5-5 and 5-6 of the LTP and are provided in Table 2 and Table 3, respectively. The Insignificant Contributor (IC) dose percentage of 10% was used to adjust the DCGLs in soils to account for the dose from the eliminated IC radionuclides. Table 2 - Base Case DCGLs for Surface Soils (BcDCGLSS) Surface Soil DCGL Radionuclide (pCi/g) Co-60 4.26 Cs-134 6.77 Cs-137 14.18 Ni-63 3,572.10 Sr-90 12.09 Table 3 - Base Case DCGLs for Subsurface Soils (BcDCGLSB) Subsurface Soil Radionuclide DCGL (pCi/g) 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/yr or less after all FSS is completed, the BcDCGLs 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 BcDCGLs 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 OpDCGL is then used as the [11]

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E DCGL for the FSS design of the survey unit (calculation of surrogate DCGLs, investigations levels, etc.). Details of the OpDCGLs 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 10) The OpDCGLs for the FSS of surface and subsurface soils are listed in Tables 5-7 and 5-8 of the LTP and are presented in Table 4 and Table 5, respectively. Table 4 - Operational DCGLs for Surface Soils (OpDCGLSS) Surface Soil DCGL Radionuclide (pCi/g) Co-60 1.091 Cs-134 1.733 Cs-137 3.630 Ni-63 914.458 Sr-90 3.095 Table 5 - Operational DCGLs for Subsurface Soils (OpDCGLSB) Subsurface Soil Radionuclide DCGL (pCi/g) Co-60 0.881 Cs-134 1.137 Cs-137 1.984 Ni-63 195.333 Sr-90 0.425 In accordance with NUREG-1757, Appendix G, if the HSA indicates that there is no likelihood of substantial subsurface residual radioactivity, subsurface surveys are not necessary. The HSA as well as the results of the extensive characterization of subsurface soils in the impacted area surrounding the Zion facility have shown that there is minimal residual radioactivity in subsurface soil. Consequently, Zion proposes to perform minimal subsurface sampling during FSS. Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest at the required scan MDC, which for Class 1 Open Land survey units, is the a priori elevated measurement comparison DCGL (DCGLEMC). 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 ensure the quality and prevent the loss of data. [12]

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E 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 maximum acceptable MDC for measurements obtained using field instruments was the a priori DCGLEMC, which was calculated using the methodology described in the LTP, Section 5.6.4.3.

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 DQO process determined that Co-60, Ni-63, Sr-90, Cs-134 and Cs-137 would be the ROC in survey unit 12201E. During FSS, concentrations for HTD ROC Ni-63 and Sr-90 are inferred using a surrogate approach. Cs-137 is the principal surrogate radionuclide for Sr-90 and Co-60 is the principal 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 and are presented in Table 6. The maximum ratios will be used in the surrogate calculations during FSS unless area specific ratios are determined by continuing characterization. Table 6 - Surrogate Ratios Auxiliary Building Ratios Mean Max 95%UCL Ni-63/Co-60 44.143 180.450 154.632 Sr-90/Cs-137 0.001 0.002 0.002 For the FSS of survey unit 12201E, the surrogate OpDCGLs for Co-60 and Cs-137 were computed based on the maximum ratios from Table 6. The equation for calculating a surrogate DCGL is as follows: Equation 1 1

Using the BcDCGLs presented in Table 2 and the maximum ratios from Table 6, the following surrogate calculations were performed: Equation 4 1 (137) = = 14.15 / 1 0.002 [(14.18 )+( )] (137) 12.09(90) The surrogate BcDCGL for surface soils that was used for Cs-137 in this survey unit for calculating the DCGLEMC is 14.15 pCi/g.

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E The surrogate BcDCGL for surface soils that was used for Co-60 in this survey unit for calculating the DCGLEMC is 3.51 pCi/g. 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 Chapter 5, Table 5-25 and are reproduced below in Table 7. Table 7 - Investigation Levels Direct Investigation Classification Scan Investigation Levels Levels

                            >Operational DCGL or >MDCscan if Class 1                                                         > Operational DCGL MDCscan is greater than Operational DCGL The MDCscan for the 2350-1/44-10 was calculated using the methodology of TSD-11-004, Ludlum Model 44-10 Detector Sensitivity (Reference 11) with the following parameters:

• background count rate of 5500 counts per minute (cpm)
• scan speed of 0.25 m/sec
• distance from detector to surface of 2
• isotopic mix of 95% Cs-137 and 5% Co-60 The calculated MDCscan value was 2.78 pCi/g, which was greater than the calculated Surrogate DCGLs, therefore the scan investigation level was set at the MDCscan of the 2350-1/44-10. The collimator was not used during the scan surveys.

The Sign Test was selected as the non-parametric statistical test. 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 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 Bound 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 /. For this survey design, a conservative estimate of the sample variability of 0.30 was used as the coefficient of variation to calculate /. The calculated relative shift was 1.67. 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 17. [15]

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E VSP was used to generate the sample map, in accordance with ZS-LT-300-001-001. The map used was provided by the Survey Mapping/CAD Specialist, with coordinates based on the NAD standard topographical grid coordinate system. The number of samples generated by VSP for a systematic triangular grid was 18. The Prospective Power Curve generated by VSP showed adequate power for the survey design. In accordance with Section 5.6.4.3 of the LTP, the a priori DCGLEMC values were calculated for the gamma emitting ROC to ensure that the MDCSCAN of the selected instrument was sufficient to detect small areas of elevated activity in the survey unit. The calculations were: 1902

• To calculate the area bounded by the systematic samples: = = = 105.7 2 18
• From the LTP, Table 5-16, the Area Factors for the next larger area, 300 m2 area were used:

o Cs-137 - 1.46 o Cs-134 - 1.30 o Co 1.16

• The DCGLEMC is the Surrogate Base Case DCGL times the Area Factor:

o The DCGLEMC for Cs-137 = 1.46 14.15 = 20.66 / o The DCGLEMC for Cs-134 - 1.30 6.77 = 8.80 / o The DCGLEMC for Co 1.16 3.51 = 4.07 / The calculated MDCSCAN, 2.78 pCi/g, is less than the DCGLEMC values calculated above, therefore, the spacing of the statistical systematic sampling and measurement locations was adequate to detect small areas of elevated radioactivity. No adjustment to the sample number was required. 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 12) 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) surface soil sample, L1-12201E-FQGS-214-SS was selected randomly for split sample analysis for the FSS of this survey unit. In accordance with Section 5.7.1.6.2 of the LTP, a subsurface soil sample was taken at 10% of the systematic surface soil sample locations in the survey unit with the location(s) selected at random. Locations L1-12201E-FSGS-203-SB and L1-12201E-FSGS-217-SB were selected for this survey unit. The locations of the eighteen (18) systematic samples are listed in Table 8. Note, samples were numbered starting with 201. This is because systematic sample numbers 1 to 17 were used in the previous FSS of this survey unit.

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 6). The maximum ratios (Table

6) will be used unless specific survey information supports the use of a surrogate ratio that is specific to the area. In these cases, the survey unit-specific radiological data and the derived surrogate ratios will be submitted to the NRC for approval. If approved, then the survey unit-specific ratios used and the survey data serving as the basis for the surrogate ratios will be documented in the release record for the survey unit.

In addition, LTP Chapter 5, Section 5.1 states that if levels of residual gamma radioactivity in an individual soil sample exceed an OpSOF of 0.1, then the sample(s) will be analyzed for HTD ROC. No soil samples exceeded an OpSOF of 0.1. Three (3) soil samples were chosen to be analyzed for HTD. Each sample was sent off-site (GEL Laboratories) for HTD analysis as specified in the FSS Sample Plan. The following samples were selected: [17]

6. SURVEY IMPLEMENTATION Survey instructions for this FSS were incorporated into and performed in accordance with FSS Sample Plan L1-12201E-F Plan #2, which was developed in accordance with ZionSolutions procedure ZS-LT-300-001-001, Final Status Survey Package Development. The FSS unit was inspected and controlled in accordance with ZionSolutions procedure ZS-LT-300-001-003, Isolation and Control for Final Status Survey (Reference 13).

For survey unit 12201E, 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, two (2) subsurface samples were obtained. Also, if during the performance of FSS, the analysis of a surface soil sample, or the results of a surface gamma scan indicated the potential presence of residual radioactivity at a concentration of 75% of the subsurface Operational DCGL, then a biased subsurface soil sample(s) would be taken to the appropriate depth within the area of concern as part of the investigation. This threshold was encountered during the FSS of survey unit 12201E during the surface scans. One (1) scan alarm was recorded during the gamma walkover survey. The area showing activity above the Action Level was marked. QC gamma walkover scans were performed of these areas, and an investigation soil sample was taken. A detailed discussion of these surveys/samples are included in Section 9 (Investigations and Results). FSS field activities were conducted under FSS Sample Plan L1-12201E-F Plan #2. 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 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. The survey required field activities were performed during normal working hours starting on June 20, 2022, and concluding on July 6, 2022. The eighteen (18) systematic surface soil sample locations were measured, using XY coordinates provided by VSP, from the southwest corner of the survey unit and marked with flags. Gamma scans were performed on 100% of the surface area of the survey unit 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 within 2 to the ground and was moved at a scan speed of approximately 0.25 meters per second. One (1) area of elevated activity was detected on the scans (see Section 9 for further discussion). Daily prior to use and daily following use, each detector was subjected to an Operational Response Check in accordance with procedure ZS-RP-108-004-011, Operation of the Ludlum Model 2350-1 Data Logger (Reference 14). The Daily Operational Response Check compared the background response and the response to [19]

FSS RELEASE RECORD - REV. 2 NORTH PROTECTED AREA YARD SURVEY UNIT 12201E check sources ranges established for normal background and detector source response to ensure that the detector was working properly. The instruments and detectors used for this survey are presented in Table 10. The instruments and detectors were verified to be properly calibrated prior to use.

In addition, two (2) subsurface samples and one (1) QC sample were collected at the randomly selected systematic sample locations. Three (3) investigation soil samples were collected at locations identified as elevated activity on the surface scans: two (2) surface samples and one (1) QC surface sample. Three (3) samples were selected for HTD radionuclide analysis.

7. SURVEY RESULTS One hundred percent (100%) of the surface of the survey unit was scanned for elevated radiation levels. Seventy-four (74) 1-m wide scan rows, as shown on the map in Attachment 1, were marked in the field and scanned with the 2350-1/44-10 using latching mode. Readings were recorded at approximately 10-meter intervals during the scans. Numerous elevated measurement locations were identified by surface scan. Table 11 provides an overview of the scan results.

(2) Ni-63 and Sr-90 are inferred concentrations using the maximum HTD ratio. The sample plan also directed that 5% of the survey unit area be surveyed for QC by gamma walkover scans, with the area to be selected by the RE. Areas selected for the QC scan included the section of the row that identified a scan reading above the Action Level for the initial survey. QC scan surveys were documented on survey 22-0139. The area covered was 100 m2, 5.4% of the survey unit. The results of the QC scans agreed with the results of the initial scan surveys. The SOF or unity rule is the mathematical test used to evaluate compliance with radiological criteria for license termination when more than one radionuclide has been determined to be potentially present. The equation for the unity rule is: Equation 6 C1 C2 Cn

                              +               +............         1 DCGL1 DCGL2                                DCGLn Where:         Cn               = concentration of radionuclide n DCGLn            = DCGL of radionuclide n.

The results of the unity rule calculation for the ROC in the systematic sample population when compared against the OpDCGLs for surface soils for survey unit 12201E are provided in Table

8. QUALITY CONTROL GEL laboratories processed two (2) split samples, L1-12201E-FQGS-214-SS and L1-12201E-QIGS-202-SS using gamma spectroscopy analysis. The data was evaluated using acceptance criteria specified in ZionSolutions procedure ZS-LT-01. There was acceptable agreement between field split results. Refer to Attachment 5 for data and quality control analysis results.

9. INVESTIGATIONS AND RESULTS An investigation was performed at the location of a scan alarm at the west end of row 70. One (1) latch reading was recorded. A field gamma spec reading taken with the Inspector 1000 identified no plant related nuclides. A DRP was not identified during the investigation. Two (2) investigation samples, L1-12201E-FIGS-202-SS and L1-12201E-QIGS-202-SS were collected.

These samples showed no activity above MDC for the ROC. An investigation sample, L1-12201E-FIGS-201-SS, was also taken of the east end of row 58, in an area that showed a higher background, to verify that plant related nuclides were not present. This sample showed no activity above MDC for the ROC.

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. 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 when compared to the Operational DCGLs. 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 Sign Test is included in Attachment 4. 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. [28]

13. ANOMALIES None.

14. CONCLUSION Survey unit 12201E 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 needed for this survey unit 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 mean BcSOF, when the analytical results were compared to the BcDCGLs, was 0.0034, which results in a dose contribution from soil in survey unit 12201E of 0.085 mrem/yr. based on the average concentration of the ROC in samples used for non-parametric statistical sampling. The conclusion of this Release Record is that survey unit 12201E 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.

** Indicates analyte is a surrogate/tracer compound.
^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence 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.

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.

^       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.

** Indicates analyte is a surrogate/tracer compound.
^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence 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.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

UI Gamma Spectroscopy--Uncertain identification UJ Gamma Spectroscopy--Uncertain identification UL Not considered detected. The associated number is the reported concentration, which may be inaccurate due to a low bias. X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y Other specific qualifiers were required to properly define the results. Consult case narrative.

^       RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL. Qualifier Not Applicable for Radiochemistry.

h Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more or %RPD not applicable.

** Indicates analyte is a surrogate/tracer compound.
^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence 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.

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.
