1. EXECUTIVE

SUMMARY

This Final Status Survey (FSS) Release Record for survey unit 10205, Switchyard, 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 (L3-10205-F #2) 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.

Fourteen (14) randomly located surface soil samples were acquired from the survey unit.

Surface scanning was not performed because of the danger, discovered and documented during characterization, of using electrical hand-held instruments in proximity to high-voltage lines discovered during characterization. The analytical results for all surface soil samples taken in survey unit 10205 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 0.1 when applying the respective Operational Derived Concentration Guideline Levels (OpDCGL). Therefore, the null hypothesis is rejected, and survey unit 10205 is acceptable for unrestricted release.

2. SURVEY UNIT DESCRIPTION The Switchyard, survey unit 10205, is an impacted Class 3 open land survey unit. It is bounded by Class 2 survey unit 10214A, 10214B, and 10214C to the north, Class 1 survey units 10204A, 10206A, 10207A, 10208A to the east, the Independent Spent Fuel Storage Installation (ISFSI) to the south, and non-impacted survey units 10216 and 10217 to the west. The total area of the survey unit is 54,573 m2.

In 2016, ComEd performed work in the Switchyard to reinforce the outer fence and add new gravel. A previous FSS, under package L3-10205-F #1, was conducted before the ComEd restoration activities took place. As a result of the work performed after the FSS was performed on the area, it was determined that another FSS would be performed, on the survey unit, once the restoration activities were concluded. Package L3-10205-F #1 is superseded by package L3-10205-F #2.

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

The ground consists of a mixture of mostly gravel and loamy soil. No vegetation is present in the survey unit. Solid physical items such as transformer pads, electrical panels, chain-link fencing, small buildings, energized high-voltage lines, and other switchyard support components are present in the area. The Switchyard is and continues to be energized.

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 this survey unit are denoted on Figure 1 located in Attachment 1.

3. CLASSIFICATION BASIS Survey unit 10205 was classified in accordance with ZionSolutions procedure ZS-LT-300-001-002, Survey Unit Classification (Reference 5).

Impacted Class 3 open land survey unit 10205 was originally designated as a Class 3 survey unit by the Historical Site Assessment (HSA) (Reference 6). 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 May 23, 2013 through June 27, 2013. The survey design for this survey unit called for the acquisition of twenty-seven (27) surface soil samples taken at random locations. Due to the nature of the equipment in this survey unit, no subsurface soil samples were required.

[8]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 The survey design also required the gamma-scan of 25% of the exposed ground surface in the survey unit using a Ludlum Model 2350-1 and a Model 44-10 Sodium Iodide (NaI) detector. During the implementation of the characterization survey, a safety concern was raised regarding the use of electrical hand-held instrumentation in close proximity to live high-voltage lines. It was decided to suspend the remainder of the scan survey and compensate with additional surface samples. Only scan area number three (3), which measures 5,009 square meters was scanned. Of the area scanned, the average observed background was 2,229 counts per minute (cpm), the mean count rate observed was 2,594 cpm and the maximum observed count rate was 5,437 cpm. One (1) scan alarm was observed in this survey unit with the scan alarm set-point set at the Minimum Detectable Count Rate (MDCR) plus background. Five (5) additional surface soil samples were obtained as investigations at biased locations.

Thirty-two (32) surface soil samples and two (2) Quality Control (QC) split samples were acquired and analyzed by the on-site gamma spectroscopy system. No plant-derived radionuclides greater that their respective Minimum Detectable Concentration (MDC) was detected in any sample in this survey unit.

The locations of surface soil samples taken during characterization in survey unit 10205 are illustrated on Figure 2 in Attachment 1. A summary of the analysis results for the surface soil samples taken during site characterization are presented in Table 1.

Table 1 - Statistical Quantities for Cs-137 and Co-60 from the 2013 Characterization Survey Cs-137 Co-60 Statistical Quantities (pCi/g) (pCi/g)

The reason for this was safety concerns with static electricity. During the implementation of the characterization survey, a safety concern was raised regarding the use of electrical hand-held instrumentation in close proximity to live high-voltage lines after a technician felt a shock in his instrument earpiece (CR-2013-0540, Injury Report 2013-39). It was determined that the use of scanning equipment was unsafe and that additional soil samples would be acquired as recompense. Because of this

[9]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 incident, the RE decided to minimize the amount of time spent in the survey unit, which meant forgoing a walk-down and scanning for FSS. 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 OpDCGLs, 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, which is in accordance with MARSSIM guidance. The appropriate design for a given survey will be 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 10205 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 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

[10]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 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.

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

[11]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 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, provide the exposure scenarios and modeling parameters that were used to calculate the site-specific DCGLs for soils (referred to a Base Case Soil DCGLs

[BcDCGL] 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 BcDCGLs 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.

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/year 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 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 9).

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

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 relative to the OpDCGL. 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. For radionuclides less than MDC, the value representing the highest abundance was selected. 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 OpDCGL were preferable while MDCs up to 50% of the OpDCGL were acceptable. The maximum acceptable MDC for measurements obtained using field instruments was 50 percent of the applicable OpDCGL.

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

[14]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 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 10205. 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.

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 Using the OpDCGLs presented in Table 5 and the maximum ratios from Table 7, the following surrogate calculations were performed:

The surrogate OpDCGL that was used for Co-60 in this survey unit for direct comparison of sample results to demonstrate compliance is 0.898 pCi/g.

The action level for investigation in a Class 3 open land survey unit is 50% of the OpDCGL. 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 surrogate adjusted gamma DCGL equals 3.494 pCi/g. The action levels for survey unit 10205 are based on 50% of the DCGL and are presented in Table 8.

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 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 () (0.08), 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 10205 was calculated as follows:

Equation 5

/ = 0.5/0.012 = 41.67 As the calculated relative shift (41.67) 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 MARSSIM 2000, a software package developed for implementation of the MARSSIM in support of the decommissioning license termination rule (10CFR20, Subpart E). The result of the MARSSIM 2000

[17]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 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, sample locations were selected at random.

The random locations of the 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 random design are listed with the GPS coordinates in Table 9.

In Class 3 open land survey units, no subsurface soil sample(s) will be taken as part of FSS survey design in accordance with LTP Chapter 5, section 5.7.1.6.2. 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 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 not encountered during the FSS of survey unit 10205.

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). The maximum ratios will be used unless 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.

No judgmental or investigational samples were acquired during the performance of FSS. A map of the random surface soil sample locations is provided on Figure 3 located in Attachment 1.

The selection of one (1) surface soil sample met the requirement that 10% of the samples collected for the FSS of survey unit 10205 be analyzed for HTD ROC. Sample L3-10205A-FRGC-011-CV was selected. The 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 sample analysis on 5% of the soil samples taken in a survey unit with

[19]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 the locations selected at random. One (1) surface soil sample, #L3-10205A-FQGC-013-CV 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. As discussed in section 3 of this Release Record, scanning during characterization was discontinued due to safety concerns. For the design of this FSS, the same concerns that arose during characterization were heeded, and it was decided that scanning would not be performed in order to negate the danger of using electrical hand-held instrumentation in close proximity to live high-voltage lines. The HSA, characterization, and process knowledge show, with confidence, that there is a negligible chance of any residual radioactivity residing in the survey unit and that scanning is not necessary to demonstrate compliance with the release criteria.

For this Class 3 open land survey unit, the Investigation Levels for soil sample measurement results are those levels specified in LTP Chapter 5, Table 5-25, and are reproduced below in Table 10.

6. SURVEY IMPLEMENTATION For survey unit 10205, compliance with the unrestricted release criteria was demonstrated through 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 OpDCGL, 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 was not encountered during the FSS of survey unit 10205. 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 exceeds a SOF (OpSOF) of 0.1 when compared against the OpDCGL, then the sample(s) will be analyzed for HTD ROC. Again, this threshold was not encountered during the FSS of survey unit 10205. Consequently, no additional surface soil samples in excess of the one surface soil sample designated during survey design were analyzed for HTD ROC.

FSS field activities were conducted under FSS Sample Plan L3-10205-F #2. The Sample Plan 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 on Friday, March 24, 2017.

The fourteen (14) random surface soil sample locations were marked with flags based on GPS coordinates provided by VSP. In accordance with FSS design, fourteen (14) surface soil samples were collected at random locations. Each surface soil sample consisted of 1 liter of soil. The sample media was sifted to remove stones and other media larger than 1 cm 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 12).

One (1) sample (L3-10205A-FRGC-011-CV) was selected for HTD radionuclide analysis.

[22]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 The implementation of survey specific QC measures included the collection of one sample (L3-10205A-FQGC-013-CV) for split sample analysis.

7. SURVEY RESULTS The on-site laboratory analyzed the fourteen (14) surface soil samples taken for non-parametric statistical testing using the on-site gamma spectroscopy system. A summary of the 14 samples collected for non-parametric statistical testing results is provided in Table 12. The results for the gamma emitting ROC (Co-60, Cs-134 and Cs-137) presented in Table 12 are the measured values from gamma spectroscopy analysis. The results for HTD ROC were inferred using the ratios presented in Table 7. Gamma spectroscopy results (summarized in Table 12) revealed no samples above MDC for Cs-137, 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 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 13). The complete gamma spectroscopy reports are presented in Attachment 5. The basic statistics for the random sample population is summarized in Table 13.

8. QUALITY CONTROL The on-site laboratory processed one split sample, L3-10205A-FQGC-013-CV, 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 14). There was acceptable agreement between field split results. Refer to Attachment 3 for data and quality control analysis results.

9. INVESTIGATIONS AND RESULTS No investigations were performed in survey unit 10205.

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 ZionSolutions Procedure ZS-LT-300-001-001, Final Status Survey Package Development states, If a selected location is found to be either inaccessible or unsuitable, then the location will be adjusted to the closest adjacent suitable location. In these cases, a notation will be made in Attachment 14, FSS Field Log, and the coordinates of the new location documented. Random sample locations 2, 8, 13 and 14 were relocated due to the presence of physical obstructions. The location coordinates presented in Table 9 are the designed coordinates.

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 15) 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 generated by MARSSIM Power 2000.

[27]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 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 OpDCGL 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 OpDCGLs. 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 4.

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

14. CONCLUSION Survey unit 10205 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 OpDCGL 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.

[28]

FSS RELEASE RECORD SWITCHYARD SURVEY UNIT 10205, Revision 1 The mean SOF, when the analytical results were compared to the Base Case DCGLs, was 0.0041, which results in a dose contribution from soil in survey unit 10205 of 0.1015 mrem/yr TEDE, based on the average concentration of the ROC in samples used for non-parametric statistical sampling.

Survey unit 10205 is acceptable for unrestricted release.

comparing with Cs-137 because Cs-137 was not positively identified in either sample. A further evaluation was performed on the K-40 data. NRC IP 84750 does not specify an agreement range for when the resolution is less than 4 because it is considered not comparable. Consequently, the comparison of the K-40 results is considered to be in agreement.
