1. EXECUTIVE

SUMMARY

This Final Status Survey (FSS) Release Record for survey unit 06201, Unit 1 Diesel Fuel Oil Storage Tank Room, 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).

The FSS Sample Plan #B1-06201AF 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).

In April of 2016, an FSS was conducted on the Turbine Building basement structure.

The sample plan design for the FSS of the Turbine Building did not include the surface area of the Unit 1 or Unit 2 Diesel Fuel Oil Storage Tank Rooms. A separate sample plan was written to include fifty-one (51) judgmental measurements to represent the surface area of the Diesel Fuel Oil Storage Tank Room. The weighted average of the judgmental ISOCS measurements was added to the systematic mean of the Turbine Building basement.

In accordance with ZSRP LTP Chapter 5, section 5.5.2.1.2 and Table 5-19, the Turbine Building survey unit has a MARSSIM classification of 3. The Diesel Fuel Oil Storage Tank Room was re-classified as a Class 1 due to it becoming a pathway for radioactive waste removed from the Auxiliary Building during decommissioning.

Final Status Survey was performed on the Diesel Oil rooms to demonstrate that the concentrations of residual radioactivity were equal to or below site-specific Derived Concentration Guideline Levels (DCGL) corresponding to the dose criterion in 10 CFR 20.1402. The Diesel Fuel Oil Storage Tank Room has a MARSSIM Classification of 1. A Sample 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. The Canberra In Situ Object Counting System (ISOCS) was selected as the primary instrument used to perform FSS. To ensure 100%

of the surface area was surveyed in accordance with the classification, fifty-one (51)

ISOCS measurement locations were selected using several adjusted Field-of-View (FOV) geometrys as specified in ZionSolutions TSD 14-022, Use of In-Situ Gamma Spectroscopy for Final Status Survey of End State Structures (Reference 5).

The results of the 51 ISOCS judgmental measurement results showed that the Sum-of-Fractions (SOF) for each measurement was less than one (1) when applying the respective Operational Derived Concentration Guideline Levels (OpDCGL) for the

[5]

FSS RELEASE RECORD UNIT 1 DIESEL FUEL OIL STORAGE TANK ROOM SURVEY UNIT 06201 Turbine Building Basement from ZionSolutions TSD 17-004, Operational Derived Concentration Guideline Levels for Final Status Survey (Reference 6). Therefore, the null hypothesis is rejected and the Unit 1 Diesel Fuel Oil Storage Tank Room is acceptable for unrestricted release.

2. SURVEY UNIT DESCRIPTION Unit 1 Diesel Fuel Oil Storage Tank Room was located on the 570 foot elevation and housed the oil for the Unit 1 Diesel Generator. The rooms were adjacent to the Turbine Building on the West side of the G (Column) Wall which divided the Turbine Building and Auxiliary Building. The entrance into the Unit 1 Diesel Fuel Oil room was from the Steam Tunnel stair wells from elevation 592 of the TB to the 570 foot elevation. (See Figure 1) The area of this structural survey unit is estimated at approximately 813 m2.

3. CLASSIFICATION BASIS The Turbine Building basement (survey unit 06100) was classified in accordance with ZionSolutions procedure ZS-LT-300-001-002, Survey Unit Classification (Reference 7). The Diesel Fuel Oil Storage Tank Room is part of the Turbine Building basement survey unit. The Turbine Building was classified as a mixture of Class 2 and Class 3 structural survey units in accordance with the Zion Station Historical Site Assessment (HSA) (Reference 8). In LTP Chapter 5, section 5.5.2, it states that the survey units designated for structures below 588 foot elevation from the HSA that were presented in LTP Chapter 2, Table 2-2 were based on screening values and source term assumptions

[6]

FSS RELEASE RECORD UNIT 1 DIESEL FUEL OIL STORAGE TANK ROOM SURVEY UNIT 06201 that are significantly different from the Basement Fill Model (BFM) and are therefore not applicable. LTP Chapter 5, section 5.5.2.1.1 states that the FSS units for the basements of the Turbine Building, the Crib House/Forebay and the Circulating Water Discharge Tunnels are designated as Class 3 as defined in MARSSIM section 2.2 in that the FSS units are not expected to contain any residual radioactivity, or are expected to contain levels of residual radioactivity at a small fraction of the DCGLs, based on site operating history and previous radiation surveys.

During decommissioning, the primary pathway into and out of the basement of the Auxiliary Building became the Unit 1 and Unit 2 570 foot elevation Diesel Fuel Oil floors. Ramps were constructed through each into the 542 foot elevation to allow for the transit of heavy equipment and removal of radioactive commodities. Due to the introduction of radioactive material into both of these areas, they were reclassified as Class 1 survey units in accordance with ZS-LT-300-001-002.

The FSS Radiological Engineer (RE) performed a visual inspection and walk-down of the survey unit on 05/30/2018 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 as part of the survey design for FSS.

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 objectives of the survey is satisfied. The DQO process 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.

[7]

FSS RELEASE RECORD UNIT 1 DIESEL FUEL OIL STORAGE TANK ROOM SURVEY UNIT 06201 The primary objective of the FSS sample plan is to demonstrate that the level of residual radioactivity in survey unit 06201 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, Technical Support Document for Potential Radionuclides of Concern During the Decommissioning of Zion Station (Reference 9) 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 described contamination levels in the basements. Concrete core samples collected during characterization surveys were obtained at biased locations where there were elevated contact dose rates and/or evidence of leaks/spills. The collected core samples were analyzed for the presence of plant-derived radionuclides.

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. LTP section 6.5.2 also states that the Auxiliary Basement ROC and the IC percentage of 5% for adjusting ROC DCGLs will also be applied to all other basements including the Diesel Fuel Oil Storage Tank Room unless different values are justified by the results of continuing characterization or FSS HTD analysis. Table 1 presents the ROC for the Auxiliary Basement and, therefore, the Diesel Fuel Oil Storage Tank Room structural surfaces and the normalized fractions based on the radionuclide mixture.

Table 1 - Dose Significant Radionuclides and Mixture

% of Total Activity Radionuclide (normalized)(1)

Co-60 0.92%

Cs-134 0.01%

Cs-137 75.32%

Ni-63 23.71%

Sr-90 0.05%

(1) Based on maximum percent of total activity from Table 20 of TSD 14-019, normalized to one for the dose significant radionuclides.

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 structures.

[8]

FSS RELEASE RECORD UNIT 1 DIESEL FUEL OIL STORAGE TANK ROOM SURVEY UNIT 06201 The End State basements will be comprised of steel and/or concrete structures which will be covered by at least three feet of clean soil and physically altered to a condition which would not realistically allow the remaining structures, if excavated, to be occupied. The exposure pathways in the BFM are associated with residual radioactivity in floors and walls released through leaching into water contained in the interstitial spaces of the fill material. The BFM assumes that the inventory of residual radioactivity in a given building is released either instantly or over time by diffusion, depending on whether the activity is surficial or volumetric, respectively. The activity released into the fill water will adsorb onto the clean fill, as a function of the radionuclide-specific distribution coefficients, resulting in equilibrium concentrations between the fill and the water.

Consequently, the only potential exposure pathways after backfill, assuming the as-left geometry, are associated with the residual radioactivity in the water contained in the fill.

The final outputs of the BFM are the Basement Derived Concentration Guideline Levels (DCGL), in units of pCi/m2, which are calculated using the BFM Groundwater (GW) and BFM Drilling Spoils Dose Factors (LTP Chapter 6, Tables 6-24 and 6-25). The DCGLs for basement structure surfaces are calculated separately for the GW and Drilling Spoils scenarios and for the summation of both scenarios. The summation DCGL is designated as the Base Case DCGL (BcDCGL) and is used during FSS to demonstrate compliance (analogous to the DCGLW as defined in MARSSIM). The BcDCGLs are radionuclide-specific concentrations that represent the 10 CFR 20.1402 dose criterion of 25 mrem/year and are calculated for each ROC and each backfilled basement.

When applied to structures, the DCGLs are expressed in units of activity per unit of area (pCi/m2). 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 BcDCGLs for the unrestricted release of the Turbine Building (including the Diesel Fuel Oil Storage Tank Rooms) are provided in Table 2. The IC dose percentage of 5%

was used to adjust the Turbine Building BcDCGLs 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 (OpDCGL) 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 TSD 17-004. The OpDCGLB for FSS of the Diesel Fuel Oil Storage Tank Room is provided in Table 3.

Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the OpDCGL. The Canberra ISOCS was selected as the primary instrument used to perform FSS of basement surfaces. Response checks were required prior to issuance and after each use. Control and accountability of ISOCS units was required to assure data quality.

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 Guidance for preparing FSS plans was provided in procedure ZS-LT-300-001-001 Final Status Survey Package Development. The Canberra ISOCS was selected as the primary instrument for performing FSS of basement surfaces. The ISOCS was selected as the instrument of choice to perform FSS of basement surfaces due to the fact that an ISOCS measurement will provide results that can be used directly to determine total activity with depth in concrete and, the surface area covered by a single ISOCS measurement is large (a nominal FOV of 10-30 m2) which essentially eliminates the need for a scan surveys.

In addition, after an ISOCS measurement is collected, it can be tested against a variety of geometry assumptions to address uncertainty in the source term geometry if necessary.

The source term geometry for ISOCS efficiency calibration, i.e., concentration depth profile and areal distribution of the residual radioactivity in structures, is required to generate efficiency curves (i.e., efficiency as a function of energy) for the ISOCS gamma spectroscopy measurements. The basis for the chosen ISOCS efficiency calibrations for the FSS of the Diesel Fuel Oil Storage Tank Rooms concrete are documented in

[11]

FSS RELEASE RECORD UNIT 1 DIESEL FUEL OIL STORAGE TANK ROOM SURVEY UNIT 06201 ZionSolutions TSD 14-022. Several different ISOCS geometries were developed for the Diesel Fuel Oil Storage Tank Rooms that ranged from a Field of View (FOV) of 50.3 m2 to a FOV of 7.06 m2. The basis for the selection of this latter geometry was the result of accessibility into open door frames with limited space.

LTP Chapter 5, section 5.5.2.1.1 states that the FSS units for the basements of the Turbine Building, the Crib House/Forebay and the Circulating Water Discharge Tunnels are designated as Class 3. During decommissioning, the primary pathway into and out of the basement of the Auxiliary Building became the Unit 1 and Unit 2 570 foot elevation Diesel Fuel Oil floors. Due to the introduction of radioactive material into both of these areas, they were reclassified as Class 1 survey units in accordance with ZS-LT-300-001-002. Consequently, the weighted average of the judgmental ISOCS measurements will be added to the systematic mean of the Turbine Building basement FSS. This is addressed in LTP Chapter 5, section 5.5.6.1. In accordance with TSD 14-014, End State Surface Areas, Volumes, and Source Terms of Ancillary Buildings (Reference 10), the total surface area of the Diesel Fuel Oil Storage Tank Room is 813 m2 .

The area-weighted SOF is calculated in accordance with LTP Chapter 5, Equation 5-8, which is reproduced as follows. The SOFBi,B variable in the equation is based on the mean of the judgmental samples.

SOFB,B = total surface SOF including all surface survey units in basement (B)

SAAdjust,B = adjusted surface area for DCGL calculation (Table 5-23) for basement (B)

SOFBi,B = SOFB for survey unit (i) in basement (B)

The sample plan for the Unit 1 Diesel Fuel Oil Storage Tank Room consisted of fifty-one (51) judgmental locations, to capture 100% of the surface area. Attachment 1, Figures and Maps, illustrates the locations of the ISOCS measurements taken.

The DQO process determined that Co-60, Ni-63, Sr-90, Cs-134, Cs-137 would be the ROC in survey unit 06202. During FSS, concentrations for Hard-to-Detect (HTD) ROC Ni-63 and Sr-90 are inferred using a surrogate approach specified in LTP section 5.2.11.

Cs-137 is the principle surrogate radionuclide for Sr-90 and Co-60 is the principle

[12]

FSS RELEASE RECORD UNIT 1 DIESEL FUEL OIL STORAGE TANK ROOM SURVEY UNIT 06201 surrogate radionuclide for Ni-63. The mean, maximum and 95% Upper Confidence Level (UCL) of the surrogate ratios were calculated in TSD 14-019 , Radionuclides of Concern for Soil and Basement Fill Model Source Terms (Reference 11) and are presented in LTP Chapter 5, Table 5-15, which is reproduced in Table 4 below.

6. SURVEY IMPLEMENTATION For the judgmental measurements performed in this survey unit 06201, compliance with the unrestricted release criteria was demonstrated through a combination of direct measurements using the ISOCS and analysis of concrete core samples obtained from the Diesel Fuel Oil Storage Tank Room. The concrete core data was used to validate the ratios of gamma emitters to HTD ROC.

A walk down was performed by FSS personnel on 05/30/18. A turnover survey was not required to accept the Diesel Fuel Oil Storage Tank Room survey unit for FSS as the implementation of the continuous characterization survey provided sufficient information pertaining to the radiological condition. The continuing characterization surveys included smears for loose surface contamination, eight (8) concrete core samples and several biased ISOCS measurements in suspect areas. All smear results were less than 1,000 dpm/100 cm2 and all ISOCS measurements indicated sum of fractions (OpSOF) of less than one when compared against the OpDCGLs. The Diesel Fuel Oil Storage Tank Room was deemed acceptable for turnover and FSS commenced on 06/01/18.

Field Logs (ZS-LT-300-001-001 Attachment 14) were used to document field activities and other information pertaining to the performance of the FSS. Daily briefings were conducted to discuss the expectations for job performance and to review safety aspects of the job.

ZionSolutions TSD 14-022 provides the initial justification for the selection of reasonably conservative geometries and efficiency calibrations for the ISOCS based on the physical conditions of the remediated surface and the anticipated depth and distribution of activity.

All ISOCS measurements were acquired using approved geometries. Various sources to detector distances were utilized due to space constraints and to ensure 100%

measurement coverage.

The ISOCS detector was positioned horizontally or vertically to the surface at the center-point of each selected measurement location. In most cases, the exposed face of the detector was positioned at a distance of 4 meters from the surface with the 90-degree collimation shield installed; this orientation corresponded to a nominal FOV of 50.3 m2, respectively. As necessary, the detector to source distance and subsequent FOV was reduced to accommodate physical constraints or obstructions while the number of measurements increased to ensure 100% areal coverage was achieved.

The measured activity for each gamma-emitting ROC (and any other gamma emitting radionuclide that was positively detected by ISOCS) was recorded (in units of pCi/m2).

Background was not subtracted from any measurement. An OpSOF calculation was performed for each measurement by dividing the reported concentration of each ROC by

[16]

FSS RELEASE RECORD UNIT 1 DIESEL FUEL OIL STORAGE TANK ROOM SURVEY UNIT 06201 the OpDCGL for each ROC to derive an individual ROC fraction. The individual ROC fractions were then summed to provide a total OpSOF value for the measurement.

Three (3) duplicate measurements were taken with the ISOCS on the Diesel Fuel Oil Storage Tank Room concrete during FSS. The locations selected for taking duplicate measurements were at locations 002, 025 and 046. These locations were randomly selected using the Microsoft Excel RANDBETWEEN function. The number of replicate measurements satisfies the requirement that a minimum of 5% percent of the number of measurements that will be used for duplicate samples in accordance with the QAPP.

7. SURVEY RESULTS The SOF or unity rule was applied to the data used for the survey planning, data evaluation and statistical tests for basement surfaces since multiple radionuclide-specific measurements were performed and concentrations inferred based on known relationships.

The application of the unity rule served to normalize the data to allow for an accurate comparison of the various data measurements to the release criteria. When the unity rule was applied, the DCGLw (used for the nonparametric statistical test) becomes one (1).

The BcDCGLB are directly analogous to the DCGLW as defined in MARSSIM. The use and application of the unity rule was performed in accordance with section 4.3.3 of MARSSIM.

As previously stated, as the extent of this survey was the acquisition of judgmental measurements at biased locations, compliance was demonstrated by direct comparison of each measurement result to the release criterion. For building surfaces, areas of elevated activity were defined as any area identified by measurement/sample (systematic or judgmental) that exceeded the OpDCGL but was less than the BcDCGL. Any area that exceeded the BcDCGL would have required remediation. This was not the case for the FSS of the Unit 1 Diesel Fuel Oil Storage Room. All measurements taken, when compared against the OpDCGL was less than an OpSOF of one. The ISOCS measured concentration results from the Unit 1 Diesel Fuel Oil Storage are listed in Table 7. Table 8 presents the mean concentration of the judgmental measurements and the Base Case SOF (BcSOF) when compared against BcDCGL.

The sample population consisted of fifty-one (51) direct measurements that were acquired using the ISOCS. The concentrations for Ni-63 and Sr-90 are inferred based on the maximum ratios as specified in LTP Chapter 5, Table 5-15. The complete ISOCS gamma spectroscopy reports are presented in Attachment 4.

Of the five (5) samples, there was no indication of plant derived radionuclides at concentrations greater than MDC. Two (2) samples were selected at random and sent to Eberline Laboratory for analysis of HTD ROC (Ni-63 and Sr-90). The analysis results indicated positive concentration of Ni-63 in sample B1-06201A-FSWC-024-CV. No other activity for any of the ROC at concentrations greater than MDC was detected in the samples. No further action or analysis was performed.

The results of the Eberline analysis are presented in Table 10 below.

8. QUALITY CONTROL The implementation of required QC measures included the collection of three additional ISOCS measurements in (survey unit 06201) for replicate measurement analysis. The complete ISOCS gamma spectroscopy reports for the replicate measurements are presented in Attachment 4. All replicate ISOCS measurements met the required acceptance criteria. The completed Replicate Sample Assessment Forms are included in Attachment 3 of this Release Record.

9. INVESTIGATION AND RESULTS No measurements were taken for an investigation during the performance of FSS in this survey unit.

10. REMEDIATION AND RESULTS No remediation was required prior to performance of FSS.

11. CHANGES FROM THE FINAL STATUS SURVEY PLAN There were no addendums to the FSS plan, however, there were changes to the ISOCS survey plans as noted earlier in this Release Record. Those changes were required due to structural interferences restricting placement of ISOCS detectors that were not obvious when the FSS plan was first written. The changes in ISOCS measurement locations were made to ensure 100% areal coverage of the survey unit.

12. DATA QUALITY ASSESSMENT (DQA)

In accordance with procedure ZS-LT-300-001-004, Final Status Survey Data Assessment (Reference 13), the DQOs, sample design, and data were reviewed for completeness, accuracy, and consistency. Documentation was complete and legible. The FSS unit was properly classified as Class 1. All measurement results were individually reviewed and validated. The FOV for the number of measurements ensured 100% areal coverage of the exposed structural surfaces. The instrumentation used to perform the FSS were in calibration, capable of detecting the activity with an adequate MDC and successfully response checked prior to and following use. An adequate number of replicate measurements were taken and the results meet the acceptance criteria as specified in the QAPP.

The analytical results of the fifty-one (51) judgmental measurements were less than an OpSOF of one.

The preliminary data review consisted of calculating basic statistical quantities (e.g.,

mean, median, standard deviation). All data was considered valid and the values reported below the MDC, and values with uncertainties that exceeded two standard deviations.

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

14. CONCLUSION Fifty-one (51) judgmental measurements were taken in Unit 1 Diesel Fuel Oil Storage Tank Room. The FOV of each measurement included the floor and three walls. The total surface area is 813 m2. The FOV for the Circular Plan geometry used for the majority of the ISOCS measurements was 28 m2, which equated to an areal coverage 100% of the surface area of the remaining Diesel Fuel Oil Storage Tank Room.

[23]

FSS RELEASE RECORD UNIT 1 DIESEL FUEL OIL STORAGE TANK ROOM SURVEY UNIT 06201 All of the measurements were below an OpSOF of one. The mean BcSOF for the survey unit was 0.004, which equates to a dose of 0.102 mrem/yr. The requirements for a Class 1 survey unit have been met.

Survey unit 06201 is acceptable for unrestricted release.

EBS-OR-43977 July19,2018 Patricia Giza Zion Solutions, LLC 101 Shiloh Blvd Zion, IL 60099 CASE NARRATIVE Work Order# 18-06123-0R SAMPLE RECEIPT This work order contains four solid samples received 06/28/2018. Samples were analyzed for Total Strontium, Tritium, Nickel-63 and by Gamma Spectroscopy.

CLIENT ID LAB ID B l-06202A-FSFC-O 16CV 18-06123-04 B l-06202A-FSWC-035CV 18-06123-05 B 1-06201 AFSWC-027CV 18-06123-06 B 1-0620 I A-FSWC-024CV 18-06123-07 ANALYTICAL METHODS Total Strontium was analyzed using EIChroM Method SR WO 1 Modified. 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 Unce1tainty 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.

[324]

ANALYTICAL RESULTS CONTINUED TOT AL STRONTIUM Samples were prepared by digesting with acids and diluting as appropriate. Aliquots were removed from dilution followed by adding Strontium recovery carriers to the samples. Chemical separations were conducted using selective extractions. Strontium precipitated was 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 repo1ied from Total Strontium assuming secular equilibrium. Chemical recovery was acceptable for all samples. The Total Strontium method blank demonstrated an acceptable result. Results for the Total Strontium duplicate demonstrated a high relative percent difference; however, normalized difference is within acceptable limits for the analytical technique. 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 transfeJTed 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 Samples were prepared by digesting with acids and diluting as appropriate. Aliquots were removed from dilution and placed into appropriately sized beakers. Stable elemental Nickel carrier was added to each sample prior to digestion. After digestion, sample pH was 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.

ANALYTICAL RESULTS CONTINUED GAMMA SPECTROSCOPY CONTINUED Samples demonstrated acceptable results for all gamma-emitting radionuclides as rep01ied. Some samples demonstrated results that are greater than the method detection limit. These results are reported from the Canberra Gamma Apex "Nuclide MDA Report" and are not positive. These results are qualified as non-detect (U). The method blank demonstrated acceptable results for all radionuclides as repo1ied. Results for the Bismuth-214 and Potassium-40 replicate demonstrated an acceptable relative percent difference and normalized difference. Results for the Cesium-137 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-13 7 laboratory control sample demonstrated an acceptable percent recovery.
