1. EXECUTIVE

SUMMARY

This Final Status Survey (FSS) Release Record for survey unit S1-011-102, Circulating Water Discharge (CWD) Pipe, 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 (LACBWR LTP) (Reference 2).

An FSS sample plan for this survey unit was developed in accordance with LaCrosseSolutions procedures LC-FS-PR-002, Final Status Survey Package Development (Reference 3) and LC-FS-PR-018, Radiation Surveys of Pipe Interiors Using Sodium/Cesium Iodide Detectors (Reference 4), the LACBWR LTP, and with guidance from NUREG-1575, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (Reference 5).

Survey unit S1-011-102 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 () and Type II () decision error rates were set at 0.05. As a systematic measurement population, five hundred and ten (510) static gamma measurements were acquired from the survey unit. The data assessment results for survey unit S1-011-102 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 0.1131 when applying the respective Operational Derived Concentration Guideline Levels (OpDCGLBP) for buried pipe. The mean SOF when applying the respective Base Case DCGLs (DCGLBP) is 0.0012. This SOF equates to a dose for the survey unit of 0.0299 mrem/yr.

2. SURVEY UNIT DESCRIPTION S1-011-102 is an impacted Class 1 buried pipe survey unit. The survey unit consists of the interior surface of the CWD Pipe. The steel pipe has an internal diameter (ID) of 60 inches and a total length of 421 feet. The pipe runs from the Turbine Building to a combined discharge structure on the banks of the Mississippi River. The interior surface area of the CWD Pipe is 614.37 m2 (6,143,736.42 cm2). Refer to Attachment 1 of this report for figures and maps depicting survey unit S1-011-102.
3. CLASSIFICATION BASIS Based on the La Crosse Boiling Water Reactor Historical Site Assessment (HSA)

(Reference 6), the CWD Pipe was identified as a Class 1 system.

5

FSS RELEASE RECORD CIRCULATING WATER DISCHARGE PIPE SURVEY UNIT S1-011-102 Based upon review of the historical information and completion of a final Survey Unit Classification Worksheet from LC-FS-PR-006, Survey Unit Classification (Reference 7),

the correct final classification of survey unit S1-011-102 was determined to be Class 1.

4. DATA QUALITY OBJECTIVES FSS 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 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 S1-011-102 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).

EnergySolutions Technical Support Document (TSD) RS-TD-313196-001, Radionuclides of Concern during LACBWR Decommissioning (Reference 8) established the basis for an initial suite of potential ROC for decommissioning. Insignificant contributors (IC) 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 9). 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 IC 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, 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 6

FSS RELEASE RECORD CIRCULATING WATER DISCHARGE PIPE SURVEY UNIT S1-011-102 ROC for the decommissioning of buried pipe at LACBWR and the normalized mixture fractions based on the radionuclide mixture.

Table 4 Dose Significant Radionuclides and Mixture for Buried Pipe 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 (1) Based on maximum percent of total activity from Table 22 of RS-TD-313196-001, normalized to one for the dose significant radionuclides.

The 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 (i.e., calculation of surrogate DCGLs and investigations levels). 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 10).

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 DCGLW.

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 buried pipe, the DCGLs are expressed in units of activity per surface area (dpm/100 cm2).

7

FSS RELEASE RECORD CIRCULATING WATER DISCHARGE PIPE SURVEY UNIT S1-011-102 Buried piping is defined as below ground pipe located outside of structures and basements.

The dose assessment methods and resulting DCGLs for buried piping are described in detail in LTP, Section 6.20. The buried piping was separated into two categories. The first category included the summation and grouping of all impacted buried pipe other than the CWD Pipe and is designated as the Buried Pipe Group. The second category consisted of the CWD Pipe only. The separation of the Circulating Water pipe was necessary because the geometry of the CWD pipe was significantly different than the other pipes, and the pipes are located in distinctly different parts of the site.

EnergySolutions TSD RS-TD-313196-004, LACBWR Soil DCGL, Basement Concrete DCGL, and Buried Pipe DCGL (Reference 11) and LTP, Section 6.20, provide the exposure scenarios and modeling parameters that were used to calculate the site-specific buried pipe DCGLs. The final DCGLs to be used during FSS account for the fact that the dose from the In Situ and Excavation scenarios must be summed in the conceptual model for buried pipe dose assessment (i.e., the In Situ and Excavation scenarios occur in parallel). The summed Buried Pipe Base Case DCGLs are reproduced in Table 4-2 below. The IC dose percentages for each of the buried pipe scenarios were used to adjust each buried pipe Base Case DCGL to account for the dose from the eliminated IC radionuclides. The Operational DCGLs for the CWD Pipe are provided in Table 4-3.

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.

In accordance with the LTP, 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 unit 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 S1-011-102 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 Waste Treatment Building. 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/buried pipe is given in Table 5-1.

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

For the survey of interior pipe surfaces, areal coverage is achieved by the area of detection for each static measurement collected. Scanning, in the traditional context, is not applicable to the survey of pipe internal surfaces. For the survey of the CWD Pipe, the detector was erroneously calibrated for a specific geometry of a 3,050 cm2 (1 ft x 1 m) area of contamination on the bottom of the pipe, resulting in inaccurate detector efficiencies and inaccurate calculations for activity per area. TSD LC-FS-TSD-005, MCNP Modeling of Water Discharge Pipes for the LaCrosse Boiling Water Reactor (Reference 12) was written 10

FSS RELEASE RECORD CIRCULATING WATER DISCHARGE PIPE SURVEY UNIT S1-011-102 to address the discrepancy in efficiency and area of detection. The TSD details the Monte Carlo Neutral Particle (MCNP) radiation transport code that modeled the response of a NaI detector to a calibration source for several different pipe sizes. The MCNP models resulted in efficiency correction factors. The calculated efficiency from original source calibration can be multiplied by the correction factors to obtain an efficiency that more realistically portrays the specific contamination geometry of the pipe. For a 60 ID pipe, each measurement has a true Field-of-View (FOV) of 14,590 cm2.

The CWD Pipe contains 421 linear feet of 60 ID steel piping, which equates to a surface area of 614.37 m2 (6,143,736.42 cm2). The LTP states that a Class 1 FSS survey unit shall have an areal coverage of 100%. Therefore, one (1) measurement was to be collected every one (1) linear foot traversed through the pipe, for a total of at least four hundred and twenty-one (421) distinct measurements over the entire accessible pathway of the piping system.

During survey design, eighty-nine (89) systematic static measurements (approximately four

[4] every twenty [20] feet) were added in an effort to assess the sides and top of the pipe (see Figure 16-2), for a total of five hundred and ten (510) static measurements that make up the systematic measurement population.

Each static measurement represents the gamma activity in gross counts per minute (cpm) for each specific measurement location. Background is subtracted, then the value is converted to dpm using an efficiency factor based on the calibration source and the efficiency correction factors detailed in TSD LC-FS-TSD-005, MCNP Modeling of Water Discharge Pipes for the LaCrosse Boiling Water Reactor. The total activity in dpm is then adjusted for the assumed effective surface area commensurate with the pipe diameter, resulting in units of dpm/100 cm2. The total gamma surface activity for each measurement was converted to an activity concentration for each gamma-emitting ROC, based on the normalized gamma mixture from Table 4-1. Concentrations for the HTD ROC Sr-90 were inferred using the surrogate approach in accordance with LTP Chapter 5.

The implementation of quality control measures as referenced by LTP, Section 5.9 and LaCrosseSolutions LC-QA-PN-001, Final Status Survey Quality Assurance Project Plan (QAPP) (Reference 13) includes the collection of replicate static measurements on 5% of the systematic measurements collected in the survey unit, with the locations selected at random. Twenty-five (25) replicate static measurements were selected for Quality Control (QC) analysis for the FSS of this survey unit.

For this Class 1 buried pipe survey unit, the Investigation Levels for measurement results are those levels specified in LTP Chapter 5, Table 5-16, and are reproduced below in Table 5-2.

6. SURVEY IMPLEMENTATION 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. The survey unit was inspected and controlled in accordance with LC-FS-PR-010, Isolation and Control for Final Status Survey (Reference 14). A Field Log was used to document field activities and other information pertaining to the performance of the FSS.

FSS field activities commenced on April 22, 2018.

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 and concluded on April 25, 2018.

Background measurements were acquired in the North Yard area of the site. These readings were found to be inconsistent with the activity measured in the pipe; nearly all measurements were negative after subtracting background. It was determined that the backgrounds originally collected for the CWD pipe were not representative of true background levels. Because the CWD pipe was no longer accessible after survey implementation, a background value was developed from the existing survey data. TSD LC-FS-TSD-003, Assessment of the LACBWR Circulating Water Discharge Pipe Final Status Survey Data for Detection Efficiency and Detector Background (Reference 15) details the process and justification for using a mean value of the data as a reasonable background value.

Daily, prior to and following use, each detector was subjected to an Operational Response Check in accordance with procedure LC-FS-PR-018, Radiation Surveys of Pipe Interiors Using Sodium/Cesium Iodide Detectors. The Daily Operational Response Check compared the background response and the response to check source ranges established for normal background and detector source response to ensure that the detector was working properly.

The five hundred and ten (510) systematic 1-minute static measurements were collected using a Ludlum Model 2350-1 paired with a Model 44-10 NaI detector operated in the rate-meter mode and using audio response. The detector was fitted into a wheeled rig, which maintained a fixed detector geometry, an area of detection of 14,590 cm2. The static MDC was sufficient to detect residual radioactivity at the action level (adjusted gross gamma Operational DCGL of 4.81E+04 dpm/100 cm2). Complete measurement results are provided in Attachment 2.

Two (2) judgmental static measurements were collected during implementation of FSS.

The implementation of survey specific QC measures included the collection of twenty-five (25) replicate static measurements for QC analysis.

7. SURVEY RESULTS 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 C1 C2 Cn

.......... .. 1 DCGL1 DCGL 2 DCGL n Where: Cn = concentration of radionuclide n DCGLn = DCGL of radionuclide n.

The application of the unity rule serves to normalize the data to allow for an accurate comparison of the various data measurements to the release criteria. When the unity rule is applied, the DCGLW (used for the nonparametric statistical test) becomes one (1). The DCGLBP 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 described in LTP, Section 5.10.3.2, the Sign Test was used to evaluate the measured residual radioactivity against the dose criterion. The SOF for each measurement was used as the sum value for the Sign Test. The Sign Test then demonstrated that the mean activity for each ROC was less than the OpDCGLBP at a Type I decision error of 0.05. The results of the Sign Test are presented in Attachment 3.

For buried pipe, areas of elevated activity were defined as any area identified by measurement (systematic or judgmental) that exceeded the OpDCGLBP but was less than the DCGLBP. The SOF (based on the OpDCGLB) for a systematic or judgmental measurement can exceed one (1) without remediation as long as the survey unit passes the Sign Test, and the mean SOF (based on the OpDCGLBP) for the survey unit does not exceed one (1). Once the survey data set passes the Sign Test (using Operational DCGLs), then the mean radionuclide activity for each ROC from systematic measurements along with any identified elevated areas from systematic and judgmental samples can be used with the Base Case DCGLs to perform a mean SOFBP calculation. The dose from residual radioactivity assigned to the FSS unit is the mean SOFBP multiplied by 25 mrem/yr.

The systematic measurement population consisted of five hundred and ten (510) static measurements that were acquired using the Ludlum Model 2350-1 paired to a Model 44-10 detector. In total, five hundred and thirty-seven (537) static measurements were collected, including the systematic, judgmental, and QC measurements. A breakdown of the total static measurements and SOF for systematic measurements compared to the OpDCGLBP is provided in Table 7-1. A summary of the results of the systematic measurements taken for 14

FSS RELEASE RECORD CIRCULATING WATER DISCHARGE PIPE SURVEY UNIT S1-011-102 non-parametric statistical testing when compared to the DCGLBP is provided in Table 7-2.

The complete results of the data assessment for survey unit S1-011-102 are provided in Attachment 2.

This SOF equates to a dose of 0.0299 mrem/yr.

8. QUALITY CONTROL The implementation of survey specific QC measures included the collection of twenty-five (25) replicate static measurements for QC analysis. The acceptance criteria for replicate static measurements is that the same conclusion is reached for each measurement. This is defined as the replicate measurement being within 20% of the standard measurement. In cases where the replicate measurement is not within 20% of the standard measurement, but both measurements are below the Operational DCGL, there is an acceptable agreement.

15

FSS RELEASE RECORD CIRCULATING WATER DISCHARGE PIPE SURVEY UNIT S1-011-102 Fourteen (14) QC replicate measurement did not fall within the 20% criteria, but both the standard and replicate measurements were well below the Operational DCGL. No further action was deemed necessary, and there is an acceptable agreement between standard and replicate results. Refer to Attachment 4 for QC analysis results.

9. INVESTIGATIONS AND RESULTS No investigations were performed during the performance or analyses of the survey.
10. REMEDIATION AND RESULTS No radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit. Chapter 4 of the LTP determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in buried pipe was ALARA.
11. CHANGES FROM THE FINAL STATUS SURVEY PLAN TSDs LC-FS-TSD-003, Assessment of the LACBWR Circulating Water Discharge Pipe Final Status Survey Data for Detection Efficiency and Detector Background, and LC-FS-TSD-005, MCNP Modeling of Water Discharge Pipes for the LaCrosse Boiling Water Reactor, were developed in response to inaccurate efficiency calibration geometries and backgrounds originally assumed in the sample plan and during survey implementation.
12. DATA QUALITY ASSESSMENT The DQO survey design and data were reviewed in accordance with LC-FS-PR-008, Final Status Survey Data Assessment (Reference 16) for completeness and consistency.

Documentation was complete and legible. Surveys 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 5).

All measurements were less than a SOF of one (1) when compared to the OpDCGLBP.

The Sign Test was performed on the data and compared to the original assumptions of the DQOs. The evaluation of the Sign Test results clearly demonstrates that the survey unit passes the unrestricted release criteria, thus, the null hypothesis is rejected.

The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). All data was considered valid including negative values, zeros, values reported below the MDC, and values with uncertainties that exceeded two standard deviations. The mean and median values for each ROC were well below the respective 16

FSS RELEASE RECORD CIRCULATING WATER DISCHARGE PIPE SURVEY UNIT S1-011-102 Operational DCGLs. Also, the retrospective power curve shows that a sufficient number of measurements were collected to achieve the desired power. Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs.

13. ANOMALIES No anomalies were observed during the performance or analyses of the survey.
14. CONCLUSION Survey unit S1-011-102 has met the DQOs of the FSS plan. The ALARA criteria as specified in Chapter 4 of the LTP were achieved.

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. Therefore, in accordance with LTP Section 5.11, the survey unit meets the release criteria.

The dose contribution from survey unit S1-011-102 is 0.0299 mrem/yr TEDE, based on the average concentration of the ROC in measurements used for non-parametric statistical testing (mean SOF).

Survey unit S1-011-102 is acceptable for unrestricted release.

This is defined as the replicate measurement being within 20% of the standard measurement. In cases where the replicate measurement is not within 20% of the standard measurement, but both measurements are below the Operational DCGL, there is an acceptable agreement.
