1. EXECUTIVE

SUMMARY

This Final Status Survey (FSS) Release Record for survey unit B2-010-103, La Crosse Boiling Water Reactor (LACBWR) Administration Building, 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-015, Final Status Surveys for Structures (Reference 3), LC-FS-PR-002 and Final Status Survey Package Development (Reference 4), the LACBWR LTP, and with guidance from NUREG-1575, Revision 1, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (Reference 5).

This above grade building survey unit has a MARSSIM classification of 2. A survey plan was designed based upon use of the Sign Test as the nonparametric statistical test for compliance. Both the Type I ((l) and Type II ( ) decision error rates were set at 0.05. As a systematic measurement population, one hundred and twelve (112) static beta measurements were acquired from the survey unit. In addition, surface scanning was performed on approximately 25% of the total surface area in the survey unit. The data assessment results for survey unit B2-010-103 indicate that the maximum gross activity among systematic measurements is equal to 1,199 dpm/100 cm2, which is 37.93% of the Adjusted Gross Operational Derived Concentration Guideline Level (DCGL) for above grade buildings (see Section 5 of this release record for the calculations of adjusted gross DCGLs). Therefore, the null hypothesis of the Sign test is rejected, and survey unit B2-010-103 is acceptable for unrestricted release. The mean gross activity among systematic measurements is equal to 113 dpm/100 cm2, which is 0.57% of the Adjusted Gross Base Case DCGL. Multiplying this fraction by 25 mrem/yr results in a dose for the survey unit of 0.1426 mrem/yr.

2. SURVEY UNIT DESCRIPTION B2-010-103 is an impacted Class 2 above grade building survey unit. The facility has historically been used for office space and records storage. It also housed an environmental lab to support the LACBWR and Genoa 3 Coal Plant operations. The total surface area of the survey unit is approximately 5,433 m2. Refer to Attachment 1 of this report for figures and maps depicting survey unit B2-010-103.

3. CLASSIFICATION BASIS Based on the La Crosse Boiling Water Reactor Historical Site Assessment (HSA)

(Reference 6), survey unit B2-010-103 was identified as a Class 2 structure survey unit.

There are no documented incidents of identified radioactive contamination, radioactive material spills or the use of unsealed radioactive sources in the LACBWR Administration Building. The Administration Building was classified as a Class 2 structure due to its proximity to the LACBWR Site Enclosure (LSE) and its previous occupancy by LACBWR facility workers. In addition, the building had equipment used to conduct whole-body counts.

A characterization survey for the LACBWR Administration Building was performed in 2014, as documented in GG-EO-313196-RS-RP-001, Characterization Survey Report for La Crosse Boiling Water Reactor (Reference 7). The initial survey design for characterization did not call for beta scanning or biased direct alpha/beta measurements; however, following the discovery of a discrete particle on the second floor of the building, additional surveys were performed. Beta scans were conducted on 50% of the accessible floor surfaces in hallways and rooms. Additionally, biased direct alpha/beta and gamma measurements, with a focus on surface areas in rooms and hallways which were stained, discolored, or disturbed, were performed. Beta scans on 10% of the roof surfaces, as well as the acquisition of six (6) random direct and removable contamination samples, were conducted. The roof was surveyed to evaluate the potential for the large, flat, and elevated open air surface to be potentially impacted by atmospheric dispersion of radioactive contamination from past LACBWR operations. The survey plan originally called for obtaining two (2) representative samples of sediments from drain lines in the facility.

However, this was not accomplished as the cleanout areas of the drain systems were not readily accessible without excavation. As an alternative, floor and sink drains in the mechanical rooms, environmental lab, and a restroom were surveyed, with direct and removable contamination surveys for alpha and beta/gamma. The results of the beta scans of carpet, laminated wood, and 12 " by 12 " tile surfaces inside the structure ranged from 1,420 dpm/100 cm2 to 2,710 dpm/100 cm2 with a scan MDC of 2,000 dpm/100cm 2. The results of beta scans of glazed type tiles located on the first floor, in and around the access control area, ranged from 3,876 dpm/100 cm 2 to 4,915 dpm/100cm2 with a scan MDC of 2,100dpm/100 cm2. Gamma spectroscopy was performed on a non-impacted sample of the glazed tile and it exhibited a significant presence of uranium and thorium NORM.

Additionally, during the beta scan survey of the second floor, a small elevated area was noted outside an office location on 12" by 12" tiles which were subsequently quantified with a hand held beta-gamma detector direct measurement to show contamination levels 6

FSS RELEASE RECORD REVISION 1 LACBWR ADMINISTRATION BUILDING ~

SURVEY UNIT B2-010-103 LACROSSESOLUTIONS nearing 6,000 dpm/100 cm2. The area and its control were turned over to the licensee for management.

The area of concern was verified to be a discrete radioactive particle (DRP) in the 12" by 12 " tile that was removed by the licensee. The DRP was verified by the on-site gamma spectroscopy unit to be an approximately 0.005 uCi discrete particle containing Cs-137. A total of ten (10) direct biased direct surveys were subsequently taken on the first and second floor laminated wood, carpet, and 12"by 12" tile areas.

The results of the surveys showed all the beta-gamma and alpha direct results were well below 50% of the action levels for structural surfaces.

The two (2) direct beta-gamma and alpha measurements on the glazed tile results demonstrated that the beta-gamma were less than 50% of the action levels for structural surfaces but were elevated at higher levels due to the presence of NORM.

The elevated alpha on the glazed tile were due to the tile's content of natural thorium and uranium series radionuclides.

The scan survey results of 10% of the roof area indicated results ranging from 1,872 dpm/100 cm2 to 2,261 dpm/100 cm2, which are well below 50% of the action level.

The direct alpha measurements were elevated with an average measurement of 112 dpm/100 cm2 and a maximum measurement of 152 dpm/100 cm 2.

Direct and removable contamination surveys were performed on nine (9) sink and floor drains. The survey results indicated no residual radioactivity exceeding 50% of the structural surface action level. Results of the survey are presented in GG-EO-313196-RS-RP-001, Characterization Survey Report for La Crosse Boiling Water Reactor.

Based upon review of the historical information, the results of the characterization survey data, and completion of a final Survey Unit Classification Worksheet, the correct final classification of survey unit B2-010-103 was determined to be Class 2.

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, utilized in accordance with MARSSIM, is described in the LACBWR LTP. 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 7

FSS RELEASE RECORD REVISION 1 LACBWR ADMINISTRATION BUILDING ~

SURVEY UNIT B2-010-103 LACROSSESOLUTIONS 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 B2-010-103 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).

LaCrosseSolutions 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 were eliminated from further detailed evaluation. Therefore, the final ROCs for LACBWR above grade buildings, soil, basement concrete, and buried piping are Cs-137, Co-60, Sr-90, Eu-152 and Eu-154.

The 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 ROC for the decommissioning of above grade buildings at LACBWR and the normalized mixture fractions based on the radionuclide mixture.

FSS RELEASE RECORD REVISION 1 LACBWR ADMINISTRATION BUILDING ~

SURVEY UNIT B2-010-103 LACROSSESOLUTIONS 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 10).

At LACBWR, compliance is demonstrated through the summation of dose from five (5) distinct source terms (i.e., basements, soils, buried pipe, above grade buildings, and groundwater) for the end-state. When applied to above grade buildings, the DCGLs are expressed in units of activity per surface area (dpm/100 cm2).

The Screening Values in NUREG-1757, Volume 2, Revision 1, Consolidated Decommissioning Guidance Characterization, Survey, and Determination of Radiological Criteria, Final Report, Table H-1, are applied to the FSS of above grade buildings. The Table H-1 Screening Values are presented as Base Case DCGLs (equivalent to 25 mrem/yr) and are reproduced in Table 4-2 below.

The Operational DCGLs for the unrestricted release of above grade buildings 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. 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 procedures LC-FS-PR-015, Final Status Surveys for Structures and LC-FS-PR-002, Final Status Survey Package Development.

For the FSS of above grade buildings, Adjusted Gross DCGLs are calculated. This is done because radionuclide-specific data is not acquired with static measurements. The equation for calculating the Adjusted Gross DCGL is as follows:

Equation 1 1

DCGLAG = [( fi ) ( fz ) ( h )]

DCGL 1 + DCGL 2 + ... DCGLi Where: DCGLAG = Adjusted Gross DCGL in units of dpm/100 cm 2 DCGLi = Gross DCGL for detectable radionuclide in units of dpm/100 cm2 fi = Mixture fraction of detectable radionuclides 10

FSS RELEASE RECORD REVISION 1 LACBWR ADMINISTRATION BUILDING ~

SURVEY UNIT B2-010-103 LACROSSESOLUTIONS Using Equation 1, and values within Tables 4-1 and 4-3, the Adjusted Gross Operational DCGL was calculated as follows:

= 19751 dpm/100 cm 2 The Adjusted Gross Base Case DCGL was calculated as 19,751 dpm/100 cm 2. The mean activity from the FSS systematic measurements is compared to the Adjusted Gross Base Case DCGL, and the dose contribution from the survey unit is calculated.

The Sign test was selected as the nonparametric statistical test for compliance with the release criteria. The number of measurements for use with the Sign test was determined in accordance with procedures LC-FS-PR-002 and LC-FS-PR-015. The relative shift (f:Jcr) for the survey unit data set is defined as shift(~), which is the Upper Boundary of the Gray Region (UBGR), or the DCGL, minus the Lower Bound of the Gray Region (LBGR),

divided by sigma (cr), which is the standard deviation of the data set used for survey design.

The optimal value for f:Jcr should range between one (1) and three (3). The largest value the

~/cr can have is three (3). If the calculated value of f:Jcr exceeds three (3), an adjusted value of three (3) will be used for f:Jcr. The ~/cr for survey unit B2-010-103, based on data from characterization of the LACBWR Administration Building, was calculated as follows:

Equation 4

= 3160/518 = 5.16 11

FSS RELEASE RECORD REVISION 1 LACBWR ADMINISTRATION BUILDING ~

SURVEY UNIT B2-010-103 LACROSSESOLUTIONS As the calculated relative shift was greater than three (3), a value of three (3) was used as the adjusted !1/cr. Both the Type I error (i.e., a value) and the Type II error (i.e., 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 hundred and twelve (112) total systematic measurements (84 interior and 28 exterior) were included in the survey design for survey unit B2-010-103. This was done because the total surface area of the survey unit surpasses the recommended Class 2 structure survey unit size from Table 1 in MARSSIM. The survey unit was split into eight (8) areas, with 14 required compliance measurements each, to accommodate the MARSSIM recommended survey unit size restrictions.

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 designated Class 2, measurement locations were selected based on a systematic grid with a random starting point. The systematic locations of the static measurements were selected using Visual Sample Plan (VSP). Input parameters included the use of survey unit drawings and the systematic sampling tool set with a predetermined number of measurement locations. The systematic measurement locations were identified in the field using dimension parameters provided on the survey unit map (see Attachment 1). Table 5-1 lists the systematic, judgmental, and QC measurements collected for FSS of survey unit B2-010-103.

Thirteen (13) replicate measurements, B2-010-103-FQFO-A09-BD, B2-010-103-FQCM-B13-BD, B2-010-103-FQWB-C13-BD, B2-010-103-FQFO-D02-BD, B2-010-103-FQCM-E06-BD, B2-010-103-FQWO-F05-BD, B2-010-103-FQRO-G06-BD, B2-010-103-FQWO-H08-BD, B2-010-103-FQFO-A21-BD, B2-010-103-FQFC-D20-BD, B2-010-103-FQSM-B16-BD, B2-010-103-FQSM-E19-BD, and B2-010-103-FQSM-B21-BD were selected at random for the QC replicate measurement analysis for the FSS of this survey unit.

The LTP, Section 5.6.4.4 and Table 5-15 specifies that for Class 2 structure survey units, systematic and judgmental surface scans will be performed on 10% to 100% of the surface area in the survey unit. For survey unit B2-010-103, 25% scan coverage was selected for the floor and walls, and 10% coverage was selected for the ceilings. This coverage equates to total scan coverage of 1,230 m2. One hundred and forty-seven (147) scan areas (one [1]

scan area at each systematic measurement location and thirty-five [35] judgmental scan areas), equating to 1,345 m2, were established. Refer to Attachment 1 for figures and maps depicting the measurement and scan locations in survey unit B2-010-103.

For this Class 2 structure survey unit, the "Investigation Levels" for area scanning and direct measurement results are those levels specified in the LTP, Table 5-16, and are reproduced below in Table 5-2.

6. SURVEY IMPLEMENTATION For survey unit B2-010-103, compliance with the unrestricted release criteria was demonstrated through a combination of surface scanning and surface static measurements with a Ludlum Model 44-116 beta/gamma detector.

An FSS Supervisor performed a visual inspection and walk-down of the survey unit during the Unconditional Release Survey (URS) that was performed prior to 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 FSS, the interior and exterior of the building was dry and reasonably free of debris. No conditions prohibited the proper collection of static and scan measurements.

SURVEY UNIT B2-010-103 LACROSSESOLUTIONS 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. 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. A "Field Log" was used to document field activities and other information pertaining to the performance of the FSS. FSS field activities commenced on October 9, 2019, and were concluded on October 16, 2019.

A total of one hundred and forty-seven (147) different scan areas, constituting an areal coverage of 1,345 m2 were scanned using a Ludlum 2350-1 paired with a Ludlum Model 44-116 detector (125 cm2 detector area). The background was established as the average of five (5) 1-minute static measurements, while maintaining the detector waist high with the detector face pointed away from the surface of interest. In survey unit B2-010-103, background ranged from 195 cpm up to 400 cpm.

All designated scan areas were scanned using a Ludlum 2350-1 paired with a Model 44-116 beta/gamma detector operated in the rate-meter mode and using audio response. The probe was positioned as close to the surface as possible and was moved at a scan speed of approximately one (1) detector width per second. Scan MDC was sufficient to detect residual radioactivity at the action level of 3,160 dpm/100cm2 (Adjusted Gross Operational DCGL). Complete scan results are provided in Attachment 2.

The one hundred and twelve (112) systematic static measurement locations were marked based on the dimensions provided on the survey map. Thirty-five (35) judgmental measurement locations were selected and marked as per the sample plan. Using the Ludlum 2350-1 paired with a Model 44-116 detector, a 1-minute static measurement was acquired at the location of highest scan indication within each systematic and judgmental scan area.

The implementation of survey specific QC measures included the collection of thirteen (13) replicate static measurements for QC analysis.

7. SURVEY RESULTS All areas identified in the FSS plan were scanned for elevated activity levels. No alarms were produced during the scanning of survey unit B2-010-103. Table 7-1 provides an overview of the scan results. Complete scan results are provided in Attachment 2.

Fraction 113 0 1,199 0 249 19,751 0.0057 0.1426 The mean activity from systematic static measurements was divided by the Adjusted Gross Base Case DCGL to derive a mean fraction. The mean fraction was then multiplied by twenty-five (25) mrem/yr to derive the dose attributed to the survey unit. For survey unit B2-010-103, the calculated dose from residual activity is 0.1426 mrem/yr.

8. QUALITY CONTROL The implementation of survey specific QC measures included the collection of thirteen (13) replicate static measurements (B2-010-103-FQFO-A09-BD, B2-010-103-FQCM-B13-BD, B2-010-103-FQWB-C13-BD, B2-010-103-FQFO-D02-BD, B2-010-103-FQCM-E06-BD, B2-010-103-FQWO-F05-BD, B2-010-103-FQRO-G06-BD, B2-010-103-FQWO-H08-BD, B2-010-103-FQFO-A21-BD, B2-010-103-FQFC-D20-BD, B2-010-103-FQSM-B16-BD, B2-010-103-FQSM-E19-BD, and B2-010-103-FQSM-B21-BD) for QC analysis. The acceptance criterion for replicate static measurements is that the same conclusion is reached for each measurement. The acceptance criterion is satisfied if the replicate measurement is 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 as well as the static MDC, there is an acceptable agreement. Seven (7) of the QC replicate measurements did not fall within the 20% criteria; however, the standard and replicate measurements for each were well below the Adjusted Gross Operational DCGL as well as the static MDC, and no further action was deemed necessary.

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 prior to or as a result of the FSS. 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 above grade buildings was ALARA.

11. CHANGES FROM THE FINAL STATUS SURVEY PLAN There were no addendums to the FSS plan.

12. DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with LC-FS-PR-008, Final Status Survey Data Assessment (Reference 12) for completeness and consistency.

Documentation was complete and legible. Scan surveys and the collection of static measurements were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 2. The survey design had adequate power as indicated by the Retrospective Power Curve (see Attachment 5).

The measurement results indicated that all measurements were less than 50% of the Adjusted Gross Operational DCGL.

Although MARSSIM states that the Sign test need not be performed in the instance that no measurements exceed 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 results of the Sign test are presented in Attachment 3.

The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). The mean and median values of the data were well below the Adjusted Gross Operational DCGL. 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 B2-010-103 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 2. Therefore, in accordance with the LTP, Section 5.11, the survey unit meets the release criteria.

The dose contribution from survey unit B2-010-103 is 0.1426 mrem/yr TEDE, based on the mean activity of measurements used for non-parametric statistical sampling.

Survey unit B2-010-103 is acceptable for unrestricted release.
