SUMMARY

This Final Status Survey (FSS) Release Record for survey unit L1-010-101C, the Waste Treatment Building (WTB) excavation, has been generated in accordance with LaCrosseSolutions procedure LC-FS-PR-009, Final Status Survey Data Reporting (Reference 1) and satisfies the requirements of Section 5.11 of the La Crosse Boiling Water Reactor License Termination Plan (LTP) (Reference 2).

An FSS sample plan for this survey unit was developed in accordance with LaCrosseSolutions procedure LC-FS-PR-002, Final Status Survey Package Development (Reference 3), the LACBWR LTP, and with guidance from NUREG-1575, Revision 1, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (Reference 4).

This survey unit has a MARSSIM classification of 1. A survey plan was designed based upon use of the Sign Test as the nonparametric statistical test for compliance. Both the Type I (a) and Type II ( ) decision error rates were set at 0.05. As a systematic sample population, fifteen (15) soil samples were acquired from the survey unit. In addition, soil scanning was performed on 100% of the total surface area in the survey unit. The analytical results for all soil samples taken in survey unit L1-010-101C indicate that the maximum Sum of Fractions (SOF), considering the concentration of all applicable Radionuclides of Concern (ROC) either by direct measurement or by inference, is equal to 0.1033 when applying the respective Operational Derived Concentration Guideline Levels (OpDCGL S) for soil.

Therefore, the null hypothesis is rejected and survey unit L1-010-101C is acceptable for unrestricted release. The mean SOF when applying the respective Base Case DCGLs (DCGLS) for soil is 0.0144. This SOF equates to a dose for the survey unit of 0.3597 mrem/yr.

2. SURVEY UNIT DESCRIPTION L1-010-101C is an impacted Class 1 excavation survey unit within open land survey unit L1-010-101. The survey unit consists of the underlying soil post-removal of the WTB. The surface area of the survey unit is 87.8 m2.

The boundary of the survey unit and the location of the soil samples were defined using a Global Positioning System (GPS). Refer to Attachment 1 of this report for figures and maps depicting survey unit L1-010-101C.

3. CLASSIFICATION BASIS Based on the Historical Site Assessment (HSA) (Reference 5), survey unit L1-010-101 was identified as a Class 1 area. As survey unit L1-010-101C consists of the underlying soils 6

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C from L1-010-101, it is also designated as Class 1. The following summarizes the results of the characterization surveys for survey unit L1-010-101.

The initial site characterization surveys performed by EnergySolutions were conducted between October 9, 2014, and August 6, 2015. In total, twelve (12) surface soil samples and eighteen (18) subsurface soil samples were collected in the survey unit. All samples were analyzed by the on-site gamma spectroscopy system. For surface soil samples, Cs-137 was detected at concentrations above Minimum Detectable Concentration (MDC) in all twelve (12) samples, at a maximum concentration of 1.07E+00 pCi/g, and Co-60 was detected at concentrations above MDC in two (2) samples, at a maximum concentration of 2.87E-01 pCi/g. For subsurface soil samples, Cs-137 was detected at concentrations above MDC in eight (8) of the samples, at a maximum concentration of 1.61E-01 pCi/g. Co-60 was not detected at concentrations above MDC for subsurface soil samples. A summary of the analyses for the surface soil and subsurface soil samples taken during site characterization are presented in Table 3-1.

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C Section 5.1 of the LTP states that the actual Insignificant Contributor (IC) dose will be calculated for each individual sample result using the DCGLs from TSD RS-TD-313196-004, LACBWR Soil DCGL, Basement Concrete DCGL, and Buried Pipe DCGL, Table 4 (Reference 6) for soil. If the IC dose calculated is less than the IC dose assigned for DCGL adjustment, then no further action will be taken. If the actual IC dose calculated from the sample result is greater than the IC dose assigned for DCGL adjustment, then a minimum of five (5) additional investigation samples will be taken around the original sample location. Each investigation sample will be analyzed by the on-site gamma spectroscopy system and sent for HTD analysis (full suite of radionuclides from LTP Table 5-1). As with the original sample, the actual IC dose will be calculated for each investigation sample. In this case, the actual calculated maximum IC dose from an individual sample observed in the survey unit will be used to readjust the DCGLs in that survey unit. If the maximum IC dose exceeds 10%, then the additional radionuclides that were the cause of the IC dose exceeding 10% will be added as additional ROC for that survey unit. The survey unit-specific DCGLs used for compliance, the ROC for that survey unit, and the survey data serving as the basis for the IC dose adjustment will be documented in the release record for the survey unit.

Two continuing characterization soil samples were collected during FSS in survey unit L1-010-101 C (L1-010-101-FSGS-C06-SB, and L1-010-101-FSGS-C14-SB) to confirm that IC dose and Sr-90 to Cs-137 ratio remained unchanged. The on-site gamma spectroscopy analysis revealed that Cs-137 was detected at concentrations above MDC in both samples, at a maximum concentration of 1.41E+00 pCi/g. Co-60 was detected in one sample at a concentration of 4.10E-02 pCi/g. A summary of the on-site analysis results are provided in Table 7-2. Both samples were sent off-site to GEL Laboratories for full suite radionuclide analysis. Inadvertently, H-3 and C-14 were not included in the suite of radionuclides for analysis. However, H-3 and C-14 were never identified in any soil sample from the site, so their absence from these particular analyses should not warrant any action. An assessment of the results of continuing characterization confirmed that the IC dose is unchanged. The maximum calculated IC dose was 0.0725 mrem/yr, which is below the 2.5 mrem/yr limit provided in the LTP for DCGL adjustment. A summary of the off-site analytical results for continuing characterization samples is provided in Table 3-3 below. Only Cs-137 and Co-60 was positively identified in the off-site analysis of the continuing characterization samples.

4. DATA QUALITY OBJECTIVES Final Status Survey planning and design relies on a properly executed Data Quality Objective (DQO) process to ensure, through compliance with explicitly defined inputs and boundaries, that the primary objective of the survey is satisfied. The DQO process is described in the LACBWR LTP in accordance with MARSSIM. The appropriate design for a given survey was 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 10

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C hypothesis would indicate that residual activity within the survey unit does not exceed the release criteria. Therefore, the survey unit would satisfy the primary objective of the FSS sample plan.

The primary objective of the FSS sample plan is to demonstrate that the level of residual radioactivity in survey unit L1-010-101C 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).

LaCrosseSolutions TSD RS-TD-313196-001, Radionuclides of Concern during LACBWR Decommissioning (Reference 7) established the basis for an initial suite of potential ROC for decommissioning. LTP Chapter 2 provides detailed characterization data that describes the results of surveys taken of soil. Surface and subsurface soil samples were taken in each impacted open land survey units and analyzed for the presence of plant-derived radionuclides. The results of surface and subsurface soil characterization in the impacted area surrounding LACBWR indicate that there is minimal residual radioactivity in soil.

Insignificant dose contributors were determined consistent with the guidance contained in Section 3.3 of NUREG-1757, Volume 2, Revision 1, Consolidated Decommissioning Guidance Characterization, Survey, and Determination of Radiological Criteria, Final Report (Reference 8). In all soil and concrete scenarios, Cs-137, Co-60, Sr-90, Eu-152 and Eu-154 contribute nearly 100% of the total dose. The remaining radionuclides were designated as insignificant dose contributors and are eliminated from further detailed evaluation. Therefore, the final ROCs for LACBWR soil, basement concrete and buried piping are Cs-137, Co-60, Sr-90, Eu-152 and Eu-154.

LTP Chapter 6, Section 6.14.1 discusses the process used to derive the ROC for the decommissioning of LACBWR, including the elimination of IC from the initial suite.

Table 4-1 presents the ROC for the decommissioning of soil at LACBWR and the normalized mixture fractions based on the radionuclide mixture.

Table 4 Dose Significant Radionuclides and Mixture for Soil Fraction of Total Activity Radionuclide (normalized)(1)

Co-60 0.064 Sr-90 0.098 Cs-137 0.829 Eu-152 0.005 Eu-154 0.003 11

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C (1) Based on maximum percent of total activity from Table 22 of RS-TD-313196-001, normalized to one for the dose significant radionuclides.

LTP, Section 5.2 states that each radionuclide-specific Base Case DCGL is equivalent to the level of residual radioactivity (above background levels) that could, when considered independently, result in a Total Effective Dose Equivalent (TEDE) of 25 mrem/yr to an Average Member of the Critical Group. To ensure that the summation of dose from each source term is 25 mrem/yr or less after all FSS is completed, the Base Case DCGLs are reduced based on an expected, or a priori, fraction of the 25 mrem/yr dose limit from each source term. The reduced DCGLs, or "Operational" DCGLs can be related to the Base Case DCGLs as an expected fraction of dose based on an a priori assessment of what the expected dose should be based on the results of site characterization, process knowledge, and the extent of planned remediation. The Operational DCGL is then used as the DCGL for the FSS design of the survey unit (calculation of surrogate DCGLs, investigations levels, etc.).

Details of the Operational DCGLs derived for each dose component and the basis for the applied a priori dose fractions are provided in LC-FS-TSD-002, Operational Derived Concentration Guideline Levels for Final Status Survey (Reference 9).

The dose contribution from each ROC is accounted for using the SOF to ensure that the total dose from all ROC does not exceed the dose criterion. A Base Case DCGL that is established for the average residual radioactivity in a survey unit is equivalent to a DCGL W.

The DCGLW can be multiplied by Area Factors to obtain a Base Case DCGL that represents the same dose to an individual for residual radioactivity over a smaller area within a survey unit.

At LACBWR, compliance is demonstrated through the summation of dose from five (5) distinct source terms for the end-state (basements, soils, buried pipe, above-ground structures, and groundwater). When applied to soil, the DCGLs are expressed in units of activity per unit of mass (pCi/g).

For LACBWR, soil is defined as a layer of soil beginning at the surface but extending to a depth of 1 m to allow for flexibility in compliance demonstration if contamination deeper than 0.15 m is encountered. Based on characterization data and historical information, there are no expectations of encountering a source term geometry that is comprised of a clean surface layer of soil over a contaminated subsurface soil layer. EnergySolutions TSD RS-TD-313196-004 and LTP Chapter 6, Sections 6.4 and 6.8 provide the exposure scenarios and modeling parameters that were used to calculate the site-specific soil DCGLs. The adjusted soil DCGLs for the unrestricted release of open land survey units as provided in Chapter 6, Section 6.16.1 are reproduced in Table 4-2. The insignificant dose contributor 12

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C percentages for the most limiting basement scenario was used to adjust the DCGLs for soil to account for the dose from the eliminated insignificant contributor radionuclides.

Survey instrument response checks were required prior to issuance and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data.

As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. The actual recorded value was used as the recorded FSS result for measurement and/or sample values that are less than MDC. Negative values were recorded as "zero." Results were not reported as "less than MDC" (< MDC). Sample report summaries included unique sample identification, analytical method, radionuclide, result, uncertainty, laboratory data qualifiers, units, and the observed MDC.

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C In accordance with the LTP, for laboratory analysis, MDCs less than 10% of the Operational DCGL were preferable while MDCs up to 50% of the Operational DCGL were acceptable.

The minimum acceptable MDC for measurements obtained using field instruments was 50% of the applicable Operational DCGL.

5. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. Guidance for preparing FSS plans is provided in procedure LC-FS-PR-002, Final Status Survey Package Development.

The DQO process validated that Co-60, Sr-90, Cs-137, Eu-152, and Eu-154 would be the ROC in survey unit L1-010-101C as presented in LTP Section 5.1. During the data analysis of the FSS results, concentrations for the HTD ROC Sr-90 are inferred using a surrogate approach. Cs-137 is the principle surrogate radionuclide for Sr-90. During characterization, both Sr-90 and Cs-137 was positively detected in all thirty (30) concrete core samples assessed in the Reactor Building, Tunnel, and WTB. The 95% Upper Confidence Limit (UCL) of the Cs-137 fractions was chosen to represent the overall nuclide mix for soils/buried pipe, the Reactor Building, and the Waste Gas Tank Vault. The surrogate ratio for soil is given in Table 5-1.

Table 5-1 Soil Surrogate Ratio Radionuclides Ratio Sr-90/Cs-137 0.502 The equation for calculating a surrogate DCGL is as follows:

Equation 1 Where: DCGLSur = Surrogate radionuclide DCGL DCGL2,3 ... n = DCGL for radionuclides to be represented by the surrogate Rn = Ratio of concentration (or nuclide mixture fraction) of radionuclide "n" to surrogate radionuclide Using the Operational DCGLs presented in Table 4-3 and the ratio from Table 5-1, the following surrogate calculation was performed:

The surrogate Operational DCGL that was used for Cs-137 in this survey unit for direct comparison of sample results to demonstrate compliance was 17.31 pCi/g.

The action levels for survey unit L1-010-101C are based on the Operational DCGL and are presented in Table 5-2.

(2) Based on the surrogate adjusted DCGL of Cs-137 while inferring Sr-90.

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 LC-FS-PR-002. The relative shift (11/u) for the survey unit data set is defined as shift(~), which is the Upper Boundary of the Gray Region (UBGR), or the DCGL (SOF of 1), minus the Lower Bound of the Gray Region (LBGR) (SOF of 0.5), divided by sigma (u), which is the standard deviation of the data set used for survey design. The optimal value for ~/u should range between one (1) and three (3) . The largest value the 11/u can have is three (3). If the

~/u exceeds three (3), then the value of three (3) will be used for 11/u. The 11/u for survey unit L1-010-101C, based on Cs-137 and Co-60 data for subsurface soil samples collected during characterization of L1-010-101, was calculated as follows:

Equation 3

= 0.5/0.03 = 16.67 15

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C As the calculated relative shift (16.67) was greater than three (3), then a value of three (3) was used as the adjusted 11/cr. Both the Type I error, or a 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 fourteen (14).

One (1) additional systematic sample location was added during survey design, for a total sample size of fifteen (15) for use with the Sign Test.

A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARSSIM in support of the decommissioning license termination rule (10CFR20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.

As the survey unit was classified as Class 1, sample locations were selected based on a systematic triangular grid with a random starting point. The systematic locations of the soil samples were selected using Visual Sample Plan (VSP), in accordance with LC-FS-PR-002.

Input parameters included use of aerial photographs and the GPS route of the boundary of the excavation. The systematic coordinates generated with VSP were integrated with a GPS to identify sample locations in the field. Table 5-3 lists the systematic samples collected for FSS and the corresponding GPS coordinates, based on the Wisconsin State Plan North American Datum 1983 coordinate system.

'IOL SURVEY UNIT L1-010-101C Sample ID Northing Easting L1-010-101-FSGS-C15-SB 571003.7518 1642221.8651 The LACBWR LTP Chapter 5, Section 5.1 states that soil samples will be collected during FSS to confirm the HTD to surrogate radionuclide ratio. Ten percent (10%) of the FSS samples collected from open land survey units (including excavations where major sub-grade structures previously resided) will be analyzed for HTD ROC. Only the HTD radionuclide included as ROC (Sr-90) will be analyzed in the FSS confirmatory samples. In addition, if any sample has a SOF of 10% of the Operational DCGL or more, it must be sent for HTD ROC analysis. For samples with positive results for both the HTD ROC and the corresponding surrogate radionuclide (Cs-137), the HTD surrogate ratio will be derived and compared against the 95% UCL ratio (see Table 5-1). If the derived ratio from the confirmatory samples exceeds the 95% UCL ratio, then the area-specific ratio as determined by actual survey data will be used.

The selection of one (1) soil sample (L1-010-101-FSGS-C06-SB) met the requirement that a minimum of 10% of the samples collected for the FSS of survey unit L1-010-101C be analyzed for HTD ROC. In addition, sample L1-010-101-FSGS-C14-SB was selected for off-site HTD ROC analysis, on the basis of a SOF greater than 10%. The selected samples were sent off-site (GEL Laboratories) for analysis of the HTD ROC as specified in LTP Chapter 5, Section 5.1. These two samples were also analyzed for the full suite of radionuclides as part of continuing characterization.

The implementation of quality control measures as referenced by LTP Chapter 5, Section 5.9 and LaCrosseSolutions LC-QA-PN-001, Final Status Survey Quality Assurance Project Plan (QAPP) (Reference 10) includes the collection of a soil sample for "split sample" analysis on 5% of the soil samples taken in a survey unit with the locations selected at random. One (1) soil sample, L1-010-101-QRGS-C03-SB, was designated for split sample QC analysis for the FSS of this survey unit.

LTP Chapter 5, Section 5.6.4.4 and Table 5-15 specifies that for Class 1 survey units, surface scans will be performed on 100% of the surface area in the survey unit. For survey unit L1-010-101C, 100% scan coverage equates to 87.8 m2. To encapsulate the entire area of the survey unit, fifty (50) half-meter wide scan lanes were established in the survey unit.

A map of survey unit is provided in Attachment 1.

For this Class 1 excavation survey unit, the "Investigation Levels" for area scanning and soil sample measurement results are those levels specified in LTP Chapter 5, Table 5-16, and are reproduced below in Table 5-4.

6. SURVEY IMPLEMENTATION For survey unit L1-010-101C, compliance with the unrestricted release criteria was demonstrated through a combination of soil scanning with a Ludlum Model 44-10 gamma detector and the sampling of soil for isotopic analysis.

An FSS Supervisor performed a visual inspection and walk-down of the survey unit on September 11, 2017, prior to performing FSS. The purpose of the walk-down was to assess the physical condition of the survey unit, evaluate access points and travel paths, and identify potentially hazardous conditions. At the time of survey, the walls of the excavation were widely sloped as to allow safe access into the survey unit. The soil in the survey unit was dry and only some concrete piers from the WTB foundation were left in the survey unit.

Nothing was noted as a considerable constraint for the safe collection of samples and scan measurements.

FSS field activities were conducted under the FSS Sample Plan, which included DQOs, survey design, detailed FSS instructions, job safety analysis, and related procedures for reference. Daily briefings were conducted to discuss the expectations for job performance and to review safety aspects of the job. A "Field Log" was used to document field activities and other information pertaining to the performance of the FSS. FSS field activities commenced on September 12, 2017.

During implementation of the FSS on September 13, 2017, elevated scan readings were identified near concrete foundation caps and residual concrete chunks that remained post-demolition of the WTB foundation. These elevated scan readings were verified by a Region III NRC Inspector who was performing confirmatory scan surveys. Count rates of up to 70,000 counts per minute (cpm) were identified in these areas. FSS Supervision determined that the elevated areas needed to be remediated and the remaining concrete in the survey unit taken out. The work crew was instructed to continue taking out soil and concrete until count rates were consistently below 10,000 cpm. Gamma scans of the material in excavator buckets during removal of the material indicated count rates of up to 1,400,000 cpm.

Approximately seventy (70) cubic yards of soil and concrete debris were removed from the excavation.

After completion of the remediation, three (3) soil samples were collected at the edges of the remediated area and analyzed using the on-site gamma spectroscopy system. Cs-137 was detected at concentrations greater than MDC in three (3) of the samples, with a maximum concentration of 2.30E-01 pCi/g. Co-60 was detected at concentrations above MDC in two (2) of the samples, with a maximum concentration of 2.71E-02 pCi/g. The results of these samples are far below the Operational DCGLs.

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION

'IOL SURVEY UNIT L1-010-101C A 100% gamma scan of the excavation (summarized in Section 7 of this release record) was performed after remediation was completed, on September 14, 2017. A total of fifty (50) half-meter wide grids (labeled E, EX, and N) were scanned using a Ludlum 2350-1 paired with a Ludlum Model 44- 10 (2"x 2") sodium iodide (Nal) detector. The background for the scan grids was established as the average of five (5) 1-minute static measurements collected in the environmental lab. The background values collected in the environmental lab (ranging from 5,004 cpm up to 5,095 cpm) were used as the final backgrounds for the scan survey.

All designated scan areas were scanned using a Ludlum 2350-1 paired with a Model 44-10 2"x 2" Nal detector operated in the rate-meter mode and using audio response. The probe was positioned no more than 3" from the ground and was moved at a scan speed of approximately 0.5 meters per second. In accordance with RS-TD-313196-006, Ludlum Model 44-10 Detector Sensitivity (Reference 11), the scan MDC was sufficient to detect residual radioactivity at the action level (adjusted surrogate DCGL of 17.31 pCi/g, which was based on the surrogate adjusted DCGL of Cs-137 while inferring Sr-90). Complete scan results are provided in Attachment 2.

After scanning was completed with no alarms, the area was backfilled. Upon further review of the FSS data and implementation, it was determined that the remediation and additional excavation in the survey unit invalidated eleven (11) of the original fifteen (15) soil samples, as those samples no longer represented the end state condition of the survey unit. In addition, the survey unit size expanded during additional excavation. A Condition Report (CR), ES-LCR-CR-2017-0073 (Reference 12), was issued on October 9, 2017, which documented the need for resurvey of L1-010-101C, in addition to reviews and revisions of several key FSS procedures to clarify what controls were needed to eliminate the potential for leaving building components or systems in below grade survey units.

The FSS sample plan was revised for the acquisition of fifteen (15) new soil samples.

Because the survey unit was backfilled, soil samples had to be collected using a GeoProbe direct push machine, which could reach and obtain soil from the end state elevation of the excavation. The scan measurements collected post-remediation of the survey unit were still valid for FSS because they represented the end state condition of the excavation. Although not required, additional scanning was performed during the collection of the new soil samples; a 1 m2 area at each sample location and, in some cases, scans of the actual samples in a low-background area, were scanned using the Ludlum 2350-1 paired with a Model 44-10 2"x 2" Nal detector. Background measurements for the sample location scans were collected in a field near a non-impacted survey unit that had little influence or "shine" from the Reactor building and ranged from 6,129 cpm up to 7,385 cpm. Field work for the revised FSS sample plan concluded on October 18, 2017.

20

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C The fifteen (15) systematic soil sample locations were marked with flags based on GPS coordinates provided. Each soil sample consisted of approximately one (1) liter of soil. The sample media was sifted to remove stones and other media larger than one (1) centimeter in diameter. All soil samples were collected, controlled, transported, stored and transferred to the on-site laboratory using the Chain-of-Custody process from LC-FS-PR-012, Chain of Custody Protocol (Reference 13), and in accordance with LC-FS-PR-004, Sample Media Collection for Site Characterization and Final Status Survey (Reference 14), LC-FS-PR-005, Sample Media Preparation for Site Characterization and Final Status Survey (Reference 15), and LC-FS-PR-001, Sample Storage (Reference 16).

The survey design specified that a minimum of one (1) sample was required for HTD ROC analysis. In total, two (2) samples (L1-010-101-FSGS-C06-SB and L1-010-101-FSGS-C14-SB) were selected for full suite radionuclide analysis. L1-010-101-FSGS-C06-SB was selected, and L1-010-101-FSGS-C14-SB was selected because of a sample SOF of 0.1033, which is greater than the 10% threshold described in the LTP.

The survey design specified one (1) sample to be collected for QC split analysis. The implementation of survey specific QC measures included the collection of one (1) sample (L1-010-101-QRGS-C03-SB) for split sample analysis.

7. SURVEY RESULTS All areas identified in the FSS Sample Plan were scanned for elevated radiation levels. No elevated measurement locations were identified by surface scan. Table 7-1 provides an overview of the scan results for all fifty (50) scan grids (identified with E, EX, and N), the 1 m2 scan areas around each sample location (identified with SP), and QC locations (identified with Q).

The Action Level for scanning was established as the average background plus 22,140 cpm.

The 22,140 cpm value is equal to the scanning instrumentation response to a Cs-137 concentration of 12 pCi/g. This value is equivalent to 22% of the IC adjusted DCGL for soil that was in use before the Operational DCGLs were established. Typically, the 25% IC adjusted DCGL value (13 pCi/g) would be used for the Action Level calculation, but a more conservative value was selected for this survey unit.

'IOL SURVEY UNIT L1-010-101C Evaluating the logged scan data to the correct and current Action Levels based on the Operational DCGL shows that nearly all the scan measurements from the E, EX, and N grids, and would have produced alarms, and in turn would have triggered the collection of investigational soil samples. It was discovered that background values for the scan grids (E, EX, and N) for this survey unit were erroneously collected in the environmental lab and were not representative of actual background levels. The lab backgrounds ranged from 5,004 cpm to 5,095 cpm. The background values for the scan measurements at the sample locations (measurements labeled with SP) were collected in a field near a non-impacted survey unit that had little influence or "shine" from the Reactor building and ranged from 6,129 cpm up to 7,385 cpm. Both sets of backgrounds are lower than the activity of scan measurements collected for FSS, which ranged from 8,449 cpm to 16,110 cpm (as shown in Table 7-1 above), though the backgrounds collected for the sample locations are a closer representation of true background in the survey unit. If the average background for the sample locations (6,824 cpm) was applied to the scan grids, and the scan data was evaluated against the current Action Levels based on the Operational DCGL, only two (2) locations would have produced alarms. Because 100% of the soil in the survey unit was scanned and no soil samples collected for FSS resulted in ROC concentrations above the Operational DCGLs, the probability of discovering an elevated soil sample is very low, even had investigational samples been collected.

The higher measurements in the data set can be attributed to "shine" from the Reactor building. The higher scan area measurements were collected in the northern portion of the survey unit, which had the least amount of natural shielding (soil) from the Reactor Building (which is south-west of the survey unit). The lower range of logged measurements were collected near the bottom of the excavation. Because of the close proximity to the Reactor Building, the background count rate varied with distance and depth below the ground surface surrounding the excavation. The field logs that detail the collection of scan measurements at the sample locations note that measurements were likely higher due to the survey unit's proximity to a ramp being used to access the Reactor building.

The on-site laboratory analyzed the fifteen (15) soil samples taken for non-parametric statistical testing using the on-site gamma spectroscopy system. A summary of the fifteen (15) samples collected for non-parametric statistical testing results is provided in Table 7-

2. Gamma spectroscopy results revealed twelve (12) samples above MDC for Cs-137 and one (1) sample above MDC for Co-60. No other ROC were positively identified. The concentration for Sr-90 was inferred based on the ratio specified in Table 5-1. The complete gamma spectroscopy reports are presented in Attachment 7. The basic statistics for the systematic sample population is summarized in Table 7-3.

Samples L1-010-101-FSGS-C06-SB and L1-010-101-FSGS-C14-SB were selected. Only the analysis of the HTD ROC Sr-90 was required for FSS, but both samples were analyzed for the full initial suite of radionuclides, as the sample were used for continuing characterization. All analyses met the required MDC. The results of the off-site analysis are provided in Table 3-3.

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C The implementation of survey specific QC measures included the collection of one (1) sample (L1-010-101-QRGS-C03-SB) for split sample analysis. The on-site laboratory analyzed the designated QC sample using the on-site gamma spectroscopy system. A summary of the analytical results for the QC sample is provided in Table 7-4. Gamma spectroscopy results revealed that the sample was above MDC for Cs-137. The concentration for Sr-90 was inferred based on the ratio specified in Table 5-1.

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 4 Ci + C2 + ......... .. Cn ~l 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 for survey unit L1-010-101C are provided in Table 7-6.

8. QUALITY CONTROL The on-site laboratory processed one (1) split samples (L1-010-101-QRGS-C03-SB) 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 17). There was acceptable agreement between field split results. Refer to Attachment 4 for data and quality control analysis results.

9. INVESTIGATIONS AND RESULTS No investigations were performed during the performance of the survey or analyses of the survey results.

10. REMEDIATION AND RESULTS The original purpose of the excavation was not to support removal of contaminated subsurface soil, but rather to support the demolition and removal of the WTB. Additional excavation was necessary to remove elevated soil and concrete after scan measurements indicated areas of activity in excess of the Operational DCGL for soil. See Section 6 of this 27

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C release record for a description and results of the Remedial Action Support Survey (RASS) conducted in survey unit L1-010-101C.

11. CHANGES FROM THE FINAL STATUS SURVEY PLAN The original FSS sample plan was revised to include the collection of fifteen (15) new soil samples after remediation invalidated previous sample results. In addition, background measurements for the performance of the scan survey were not collected in the field as prescribed by the sample plan, but rather were erroneously collected in the environmental lab. See sections 6 and 7 of this release record, which provide details on the scan survey in this survey unit.

12. DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with LC-FS-PR-008, Final Status Survey Data Assessment (Reference 18) for completeness and consistency.

Documentation was complete and legible. Surveys and the collection of samples were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 1. The survey design had adequate power as indicated by the Retrospective Power Curve (see Attachment 6).

The analytical results indicated that all samples were less than a SOF of one (1) when compared to the OpDCGLS.

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 results are provided in Attachment 3.

The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). All data was considered valid including negative values, zeros, values reported below the MDC, and values with uncertainties that exceeded two standard deviations. The mean and median values for each ROC were well below the respective Operational DCGLs. Also, the retrospective power curve shows that a sufficient number of samples were collected to achieve the desired power. Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs.

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C The mean of all identified isotopes are less than the Consultation Triggers for Residential Soil Concentration depicted in Table H.1 of NUREG 1757, Vol.1, Rev. 2 (MOU Table 1).

The full table is included in Attachment 5 of this release record.

The data for Cs-137 is presented graphically through a frequency plot and quantile plot. All graphical presentations are provided in Attachment 6.

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

14. CONCLUSION Survey unit L1-010-101C has met the DQOs of the FSS plan. The ALARA criteria as specified in Chapter 4 of the LTP were achieved. The Elevated Measurement Comparison for soils was not applicable, and remediation was not required.

All identified ROC were used for statistical testing to determine the adequacy of the survey unit for FSS. Evaluation of the data shows that none of the systematic ROC concentration values exceeds the OpDCGLS; therefore, in accordance with LTP Section 5.11, the survey unit meets the release criteria.

The sample data passed the Sign Test. The null hypothesis was rejected. The Retrospective Power Curve showed that adequate power was achieved. The survey unit is properly classified as Class 1.

The dose contribution from soil in survey unit L1-010-101C is 0.3597 mrem/yr TEDE, based on the average concentration of the ROC in samples used for non-parametric statistical sampling.

Survey unit L1-010-101C is acceptable for unrestricted release.

FSS RELEASE RECORD REVISION 1 WTB EXCAVATION SURVEY UNIT L1-010-101C Table H.1 Consultation Triggers for Residential and Commercial/Industrial Soil Contamination (MOU Table 1)

Except for radium-226, thorium-232, or total uranium, concentrations should be aggregated using a sum of the fraction approach to determine site-specific consultation trigger concentrations. This table is based on single contaminant concentrations for residential and commercial/industrial land use when using generally accepted exposure parameters. Table users should select the appropriate column based on the site's reasonably anticipated land use.

Fe-55/N i-59 /N i-63 Co-60/Nb-94/Cs-137 /Eu-152/Eu-154/Eu-155 Sr-90/Tc-99 Pu238/239/240/241 Np-237 Am241/243 Cm243/244 For each soil sample with all analyses on normal turnaround.

Edie, could you let me know if GEL can proceed with these analyses on this email direction or what else I would need to do please .
