SUMMARY

This Final Status Survey (FSS) Release Record for Survey Unit 12101, Waste Water Treatment Facility (WWTF) Sludge Drying Bed 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).

An FSS package (L1-12101A-F) 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, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (Reference 4).

This open land survey unit has a MARSSIM classification of one. A survey plan was designed based upon use of the Sign Test as the nonparametric statistical test for compliance. Both the error rates were set at 0.05. Seventeen (17) 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. No areas of elevated activity were detected during the scans. The analytical results for all soil samples taken in survey unit 12101 indicate that the Sum of Fractions (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 0.200. The mean OpSOF for the systematic samples was 0.055. The mean Base Case SOF (BcSOF), when the analytical results were compared to the Base Case DCGLs (BcDCGL), was 0.014, which results in a dose assigned to the survey unit of 0.355 mrem/year.

Therefore, the null hypothesis is rejected and survey unit 12101 is acceptable for unrestricted release.

2. SURVEY UNIT DESCRIPTION Survey unit 12101, WWTF Sludge Drying Bed Area, is a Class 1 open land survey unit that is 2,036 m2 in size. It is bounded on the west by survey unit 12201E, the south by survey unit 12102, the east by survey unit 10223, and the north by survey units 10201D and 10202D.

The topography of the survey unit is mainly flat with some small dips and depressions. The soil is mostly loam. There is a fence running along the east side of the survey unit.

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 12101 was classified in accordance with ZionSolutions procedure ZS-LT-300-001-002, Survey Unit Classification (Reference 5).

The area encompassing this survey unit was described in the Zion Station Historical Site Assessment (HSA) (Reference 6) as the WWTF Area and was located within survey unit 10101 as identified in Figure 3 of the HSA. Subsequently, in the LTP, the area of survey units 10112 and 10101 that was inside the Security Area fence line was split into three survey units, 12101, 12102, and 12103. Survey unit 12101 was described as the WWTF Sludge Drying Bed Area in Table 2-4 of the LTP. The location of these survey units is represented in Figure 2-7 of the LTP, which is replicated below as Figure 1.

Figure 1 - Class 1 and Class 2 Open Land Survey Units from Figure 2-7 of the LTP A Characterization Survey was performed in September 2012 for survey unit 12101. This characterization survey consisted of gamma walkover scans using a Ludlum Model 2350-1 and a Model 44-10 (2 x 2) sodium iodide (NaI) detector. These scans identified areas with activity above the Minimum Detectable Count Rate (MDCR) of the instrument. Investigations were performed and thirteen (13) of these locations were selected for surface and subsurface sampling.

[8]

FSS RELEASE RECORD - REV. 1 WWTF SLUDGE DRYING BED AREA SURVEY UNIT 12101 Characterization samples were taken in June 2013 at the thirteen (13) locations identified from the previous survey. The results were:

Thirteen (13) surface soil samples were taken, two (2) of which had positive activity for Cs-137. The activities for the two samples were 0.16 and 0.21 pCi/g. Co-60 was less than the Minimum Detectable Concentration (MDC) for all samples.

Thirteen (13) locations had subsurface samples taken to a depth of three (3) meters, composited in 1-meter intervals. One (1) of the samples had positive Cs-137 activity at 0.08 pCi/g. All of the subsurface samples were < MDC for Co-60.

In August of 2014, a surveillance survey was performed in the three WWTF Drying Beds.

Gamma walkover scans were performed, which identified seven (7) points with activity above the MDCR of the instrument. Nine (9) investigation samples were taken, three (3) in each of the beds. Cs-137 was detected in all nine (9) samples, ranging from 0.21 to 4.72 pCi/g. Co-60 was identified in six (6) samples, ranging from 0.18 to 1.83 pCi/g. The soil in the three WWTF Drying Beds was subsequently removed.

In August of 2015, the security fence was removed at the north Section of survey unit 12101, enabling access to the area between the double fence. A gamma walkover survey was performed of this area of the survey unit. No areas of activity above the MDCR of the instrument were identified.

In April and May of 2017, excavations were performed to remove buried pipe in survey units 12101, 12102, and 12103. Surveys and sampling were performed during this pipe removal on a Radiological Assessment (RA) survey. Gamma scans on the pipe Sections and excavated soil showed no activity above the MDCscan of the instrument, and soil samples showed no activity above MDC for the Radionuclides of Concern (ROC).

In February of 2019, scans and surface/subsurface sampling was performed in the drying bed area to ensure the activity identified in 2014 had been removed. The gamma walkover scans did not identify any areas of activity above MDCR. Four (4) sample locations were marked, at the approximate locations of the 2014 samples. One (1) surface sample had Cs-137 activity above MDC, at 0.06 pCi/g. Two (2) subsurface samples had Cs-137 activity above MDC, at 0.17 pCi/g and 0.18 pCi/g.

A Radiological Engineer (RE) and a Characterization/License Termination (C/LT) Supervisor performed a visual inspection and walk-down of the survey unit on February 21, 2019, prior to performing FSS. The purpose of the walk-down was to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

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 12101 was correctly classified as Class 1.

4. DATA QUALITY OBJECTIVES 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, utilized in accordance with MARSSIM, is described in the ZSRP LTP. 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 12101 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, Technical Support Document for Potential Radionuclides of Concern During the Decommissioning of the Zion Station (Reference 7), 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), was written to refine the initial selection of ROC for decommissioning at the 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 TSD 14-019 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 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.

[10]

FSS RELEASE RECORD - REV. 1 WWTF SLUDGE DRYING BED AREA SURVEY UNIT 12101 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, Section 6.8 provide the exposure scenarios and modeling parameters that were used to calculate the site-specific DCGLs for soils (referred to as Base Case Soil DCGLs [BcDCGL] in this Release Record).

At ZNPS, compliance is demonstrated through the summation of dose from four distinct source terms (basements, soils, buried pipe and groundwater). for the end-state. 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.

[11]

FSS RELEASE RECORD - REV. 1 WWTF SLUDGE DRYING BED AREA SURVEY UNIT 12101 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.

Co-60 3.44 Cs-134 4.44 Cs-137 7.75 Ni-63 763.02 Sr-90 1.66 Each radionuclide-specific BcDCGL is equivalent to the level of residual radioactivity (above background levels) that could, when considered independently, result in a TEDE of 25 mrem/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 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 10).

[12]

FSS RELEASE RECORD - REV. 1 WWTF SLUDGE DRYING BED AREA SURVEY UNIT 12101 The OpDCGLs for the FSS of surface and subsurface soils are listed in Tables 5-7 and 5-8 of the LTP and are reproduced below in Table 4 and Table 5, respectively.

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, the ZSRP performed 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.

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

[13]

FSS RELEASE RECORD - REV. 1 WWTF SLUDGE DRYING BED AREA SURVEY UNIT 12101 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 Operational DCGL were preferable while MDCs up to 50% of the OpDCGL 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 12101. 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 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.

For this Class 1 open land survey unit, the Investigation Levels for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-25, 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 5,000 counts per minute (cpm) scan speed of 0.5 m/sec distance from detector to surface of 2 inches isotopic mix of 95% Cs-137 and 5% Co-60 The calculated MDCscan value was 3.75 pCi/g, which was greater than the calculated Surrogate DCGLs, therefore the scan investigation level was set at the MDC scan of the 2350-1/44-10. The collimator was used during the scan surveys to lower the background count rate.

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.

FSS RELEASE RECORD - REV. 1 WWTF SLUDGE DRYING BED AREA SURVEY UNIT 12101 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 seventeen (17).

The computer program Visual Sample Plan (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/Computer Assisted Design Specialist, with coordinates based on the Illinois State Plane NAD 1983 standard topographical grid coordinate system. The number of samples generated by VSP for a systematic triangular grid was 17. 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 MDC SCAN of the selected instrument was sufficient to detect small areas of elevated activity in the survey unit. The calculations were:

To calculate the area bounded by the systematic samples: = = = 119.8 From the LTP, Table 5-16, the Area Factors for the next larger area (300 m 2) 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, 3.75 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, 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 (L1-12101A-FQGS-009-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 L1-12101A-FSGS-002-SB and L1-12101A-FSGS-008-SB were selected for 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. The maximum ratios 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, 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. Four (4) samples, L1-12101A-FSGS-011-SS, L1-12101A-FSGS-012-SS, L1-12101A-

These soil samples satisfy the requirement that 10% of the samples collected for the FSS of survey unit 12101 be analyzed for HTD ROC. Each sample was sent off-site (Eberline Analytical) for analysis of the HTD ROC as specified in LTP Chapter 5, Section 5.1.

6. SURVEY IMPLEMENTATION Survey instructions for this FSS were incorporated into and performed in accordance with FSS sample plan L1-12101A-F, 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 12101, 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 and analyzed. 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 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 12101.

FSS field activities were conducted under FSS sample plan L1-12101A-F. 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 February 25, 2019, and concluding on March 6, 2019.

The seventeen (17) systematic surface soil sample locations were marked with flags based on GPS coordinates provided by VSP.

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 (2 x 2) NaI detector operated in the rate-meter mode and using audio response. The probe was positioned within 2 inches to the ground and was moved at a scan speed of approximately 0.5 meters per second. No areas of elevated activity were detected on the scans. Daily, prior to and 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 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 were collected at the randomly selected sample locations.

Four (4) samples (L1-12101A-FSGS-011SS, L1-12101A-FSGS-012-SS, L1-12101A-FSGS-014-SS, and L1-12101A-FSGS-002-SB) 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. Sixty-nine (69) 1-meter 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. No elevated measurement locations were identified by surface scan. Table 11 provides an overview of the scan results.

Complete scan results are provided in Attachment 2.

FSS RELEASE RECORD - REV. 1 WWTF SLUDGE DRYING BED AREA SURVEY UNIT 12101 The mean of all identified isotopes are less than the Consultation Triggers for Residential and Commercial/Industrial Soil Contamination depicted in Table H.1 of NUREG 1757, Vol. 1, (MOU Table 1). The full table is included in Attachment 3 of this Release Record.

8. QUALITY CONTROL The on-site laboratory processed one (1) split sample, L1-12101A-FQGS-009-SS, using gamma spectroscopy analysis. The data was evaluated using acceptance criteria specified in ZionSolutions procedure ZS-LT-01, Quality Assurance Project Plan (for Characterization and FSS). The standard sample and QC sample did not both have positive results for gamma-emitting ROC; therefore, K-40 was used in the QC comparison. There was acceptable agreement between field split results. Refer to Attachment 5 for data and quality control analysis results.

9. INVESTIGATIONS AND RESULTS No investigations were performed in survey unit 12101.

10. REMEDIATION AND RESULTS No remediation was performed in this survey unit.

11. CHANGES FROM THE 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. The sampling design had adequate power as indicated by the Retrospective Power Curve. The analytical results of all samples were less than an OpSOF 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

[29]

FSS RELEASE RECORD - REV. 1 WWTF SLUDGE DRYING BED AREA SURVEY UNIT 12101 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 6.

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

14. CONCLUSION Survey unit 12101 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 exceed 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 mean BCSOF, when the analytical results were compared to the B CDCGLs, was 0.014, which results in a dose contribution from soil in survey unit 12101 of 0.355 mrem/year TEDE, 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 12101 is acceptable for unrestricted release.

Laboratory qualifiers are as follows:

U - Result is less than the MDA.

ANALYTICAL RESULTS Combined Standard Unce1tainty is rep01ted at I-sigma value.

Minimum Detectable Activity (MDA) values for data represented in this repo1t are sample-specific. MDA measurements are determined based on factors and conditions including instrument settings, aliquot size and matrix type.

ANALYTICAL RESULTS CONTINUED TOTAL STRONTIUM Samples were prepared by leaching aliquots as appropriate and adding Strontium recovery carriers to each sample. Chemical separations were conducted using selective extractions. Strontium precipitates were mounted on tared filter media. Chemical recovery was determined by Strontium carrier mass determinations. Samples were counted by gas flow prop01tional counting and corrected for Yttrium-90 ingrowth.

Samples demonstrated acceptable results for all Total Strontium analyses. Strontium-90 results are reported from Total Strontium activity assuming secular equilibrium. All results demonstrated slightly high method detection limits. Chemical recovery was acceptable for all samples. The Total Strontium method blank demonstrated an acceptable result. Results for the Total Strontium duplicate demonstrated an acceptable relative percent difference and normalized difference. Results for the Total Strontium laboratory control sample demonstrated an acceptable percent recovery.

Tritium was performed using Method LANL ER-210 Modified. Nickel-63 was performed using Method ASTM 3500-Ni Modified.

Gamma Spectroscopy was performed using EPA Method 901.1 Modified.

Laboratory qualifiers are as follows:

U - Result is less than the MDA.

ANALYTICAL RESULTS Combined Standard Uncertainty is reported at I-sigma value.

Minimum Detectable Activity (MDA) values for data represented in this report are sample-specific.

MDA measurements are determined based on factors and conditions including instrument settings, aliquot size and matrix type.

Page 1 of 3 0014

ANALYTICAL RESULTS CONTINUED TOT AL STRONTIUM Samples were prepared using selective extractions. Strontium precipitates were mounted on tared filter media. Chemical recovery was determined by Strontium carrier mass determinations. Samples were counted by gas flow proportional counting and corrected for Yttrium-90 ingrowth.

Samples demonstrated acceptable results for all Total Strontium analyses. Strontium-90 results are reported from Total Strontium. Chemical recovery was acceptable for all samples. The Total Strontium method blank demonstrated an acceptable result. Results for the Total Strontium duplicate demonstrated an acceptable relative percent difference and normalized difference. Results for the Total Strontium laboratory control sample demonstrated an acceptable percent recovery.

TRITIUM A representative aliquot of each sample was equilibrated with Tritium free water. Equilibrates were transferred into round-bottomed distillation flasks and attached to single stage stills. A portion of each middle distillation fraction was transferred to a liquid scintillation vial and cocktail was added. Samples were then counted by beta liquid scintillation.

Samples demonstrated acceptable results for all Tritium analyses. The Tritium method blank demonstrated an acceptable result. Results for the Tritium duplicate demonstrated a high relative percent difference; however, normalized difference is within acceptable limits for the analytical technique.

Results for the Tritium laboratory control sample demonstrated an acceptable percent recovery.

NICKEL-63 A representative aliquot of each sample was placed into an appropriately sized beaker. Stable elemental Nickel carrier was added to each sample prior to digestion. Samples were digested in concentrated Nitric acid. After digestion, sample pH adjusted and Nickel-63 was precipitated selectively with Dimethylglyoxime. Precipitates were selectively separated, redissolved, and residual acid was effectively neutralized. Sample residuals were placed into scintillation vials, scintillation cocktail was added and Nickel-63 activity was determined by beta liquid scintillation.

Samples demonstrated acceptable results for all Nickel-63 analyses. The Nickel-63 method blank demonstrated an acceptable result. Results for the Nickel-63 duplicate demonstrated a high relative percent difference; however, normalized difference is within acceptable limits for the analytical technique. Results for the Nickel-63 laboratory control sample demonstrated an acceptable percent recovery.

GAMMA SPECTROSCOPY Samples for Gamma Spectroscopy analysis were prepared by transferring a known mass of each homogenized sample to a standard geometry container. Samples were counted on a High Purity Germanium (HPGe) gamma ray detector.

Page 2 of 3 0015

ANALYTICAL RESULTS CONTINUED GAMMA SPECTROSCOPY CONTINUED Samples demonstrated acceptable results for all gamma-emitting radionuclides as reported. The method blank demonstrated acceptable results for all radionuclides as reported. Results for the Bismuth-214 and Potassium-40 replicate demonstrated an acceptable relative percent difference and normalized difference.

Results for the Cobalt-60 replicate demonstrated a high relative percent difference; however, normalized difference is within acceptable limits for the analytical technique. Results for the Cobalt-60 and Cesium-137 laboratory control sample demonstrated an acceptable percent recovery.
