SUMMARY

The Alan J. Blotcky Reactor Facility (AJBRF) is located in the Omaha Veterans Affairs Medical Center (VAMC) in the city of Omaha, Nebraska. The Omaha VAMC is located in a commercial area within the city limits, and the reactor facility is housed in the southwest corner basement of Building One. The reactor facility contained a low-power Mark l Training, Research, Isotopes, General Atomics (TRIGA) nuclear reactor, which was operated as a source for neutron activation analysis of biological samples and for hot atom chemistry research. Additionally, from 1989 to 2001, the reactor was used for training Fort Calhoun Station nuclear power reactor operators.

The AJBRF initial Operating License No. R-57 was issued on June 26, 1959. The most notable license amendment, Amendment 9, was issued on April 12, 1991, to allow for operation of the reactor at steady-state power levels up to a maximum of 20 kilowatts (kW) thermal and for the installation of a microprocessor-based neutron monitoring system. The most recent license renewal was issued as Amendment 12 [Reference 1] approving the Alan J. Blotcky Reactor Facility Decommissioning Plan

[Reference 2].

The facility ceased operation of the reactor on November 5, 2001. The fuel elements were subsequently removed and shipped to the U.S. Geological Survey TRIGA reactor in Denver, Colorado in June 2002.

The facility underwent decommissioning activities from July 2015 through November 2015 followed by Final Status Surveys (ESS) using calibrated instruments to measure total (static) beta activity and to perform radiological scan measurements. Smears were also collected for tritium and beta at every measurement location plus several items based on professional judgment. A total of 173 measurement locations and twelve (12) concrete sampling locations were used to assess the final radiological status of the facility.

All total beta measurements were less than the release criteria for the most restrictive isotope (Cobalt 60 at 7,100 disintegrations per minute per 100 square centimeters [DPM/100 cm 2]) and all scan measurements were less than the investigation levels. The maximum result surveyed on a building surface was 1,284 DPM/100 cm2 on the floor in Room 526.

Nine concrete samples had detectable radionuclides at very low levels with the most elevated result being for Europium-152 at 3.66 picocuries per gram (pCi/g) which is approximately 53 percent of the screening level criteria (6.9 pCi/g).

Based on the results described in Section 4.0 of this FSS report, the AJBRF meets the requirements for unrestricted release specified in 10 Code of FederalRegulations 20, Subpart E, Radiological Criteriafor License Termination [Reference 3], by meeting the requirements of the NRC approved AJBRF-FSSP-01 FinalStatus Survey Plan [Reference 4] and the DP [Reference 2].

2.0 INTRODUCTION

2.1 Purpose and Objective This report describes the purpose, scope, and technical approach used during the FSS of the AJB RF.

The purpose of the FSS activities is to demonstrate that the radiological conditions at the facility satisfy the release criteria and the U.S. Nuclear Regulatory Commission (NRC) license may be terminated. For the purpose of this demonstration, each survey unit is independently evaluated. The objective of the survey is to demonstrate at a 95 percent minimum level of confidence that the radiological release conditions have been met.

2.2 Project Background The AJBRF is located in the Omaha VAMC in the city of Omaha, Nebraska. The Omaha VAMC is located in a commercial area within the city limits, and the reactor facility is housed in the southwest corner basement of Building One. The reactor facility contained a low-power Mark I TRIGA nuclear reactor, which was operated as a source for neutron activation analysis of biological samples and for hot atom chemistry research. Additionally, from 1989 to 2001, the reactor was used for training Fort Calhoun Station nuclear power reactor operators.

The AJBRF initial Operating License No. R-57 was issued on June 26, 1959. The most notable license amendment, Amendment 9, was issued on April 12, 1991, to allow for operation of the reactor at steady-state power levels up to a maximum of 20 kW thermal and for the installation of a microprocessor-based neutron monitoring system. The most recent license renewal was issued as Amendment II on August 5, 2002, authorizing operation for an additional 20 years (VA, 2002a).

The facility ceased operation of the reactor on November 5, 2001. The reactor core, defueled in June 2002, was located in a reactor tank that was 21 feet deep and 6.5 feet in diameter, located below grade in Room 526. The tank contained approximately 5,000 gallons of demineralized water. The fuel elements were removed and shipped to the U.S. Geological Survey TRIGA reactor in Denver, Colorado in June 2002.

There was no history of major accidents or spills.

2.3 Decommissioning Activities During 2015, the facility underwent full decontamination and decommissioning (D&D) activities to support the termination of NRC License No. R-57. D&D activities were conducted by NorthStar Federal Services, Inc. (NorthStar) in accordance with the NRC-approved DP [Reference 2]. The NorthStar team began project planning in May 2015 with the development of all plans and procedures needed to perform the decommissioning activities. Following owner review and approval of the plans and procedures, the team mobilized personnel to prepare the site for D&D activities. Radiological D&D activities began in early July 2015 and were conducted through November 2015.

The D&D activities consisted of disposing or free releasing miscellaneous equipment from the facility; removing the control rods, dummy fuel rods, drives, bridge, and reactor assembly from the reactor tank; draining the tank water; and removing the activated sections of reactor tank steel liner and gunite. The filtration system, cooling compressor, and associated piping were removed and disposed of as low-level radioactive waste (LLRW). After all items were removed from the pool, the water was analyzed with the results less 10 CFR 20 [Reference 3] Appendix B Table 2 Column 3 concentration levels for releases to sewers. The water was released to the sanitary sewer.

Following removal of reactor internals and poo1 water, a 12 inch long by 3 inch diameter concrete core drill was advanced through twelve (12) locations in the sidewalls and the reactor pit floor to collect samples for analysis to investigate the depth of activation in the reactor pit. The core drill was advanced horizontally through the gunite, steel, and concrete at the core mid plane and at one location vertically downward at the axial centerline of the reactor tank. Additional cores were advanced at elevations up to six feet above the reactor pit floor. Surface radiological measurements at the 6 foot elevation were background. Each core

rAlan Excellence--Every project. Every day.

J. Blotcky Reactor Facility Final Status Survey Report was then segmented by layer, i.e., gunite, steel, and concrete. The gunite layer ranged from approximately 2 to 4 inches thick, the steel liner was from 1/4A to 1/2/inch thick, and the concrete was approximately 9 inches thick. Samples were sent to an off-site radioanalytical laboratory for analysis of the Radionuclides of Concern (ROCs) listed in Table 3-1 below, including analysis of the hard-to-detect radionuclides Tritium, Carbon-14, lron-55, and Nickel-63.

The analysis of the cores revealed that the lower six-foot of the reactor pit required remediation. The activated gunite lining was removed from the reactor tank walls and disposed of as LLRW. An oxyacetylene torch was used to cut away the steel liner located in the floor and lower 6 feet of the reactor pit including portions of the steel liner where sample results indicated concentrations less than the release criteria. All the steel was sized and packaged as LLRW. Each of the core samples was collected in accordance with the FSS Plan [Reference 4] in order to utilize relevant portions of the sample data for FSS.

Following the removal of all radiologically impacted materials, the FSS was conducted in the facility using the methodology described in the following section.

t* Alan J. Blotcky Reactor Facility Exce/ferce--Ev ry proiect. Evei day. Final Status Survey Report 3.0 FINAL STATUS SURVEY METHODOLOGY The ESS provided data and information to demonstrate that the facility complies with the NRC annual dose limit criteria of 25-millirem (mrem) per year Total Effective Dose Estimate (TEDE) the radiological criteria listed in the NRC approved DP [Reference 21.

The FSS was designed in accordance with the NRC's NUREG-15 75, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) [Reference 5], and the NRC-approved FSS Plan [Reference 4], in order to demonstrate that the facility complies with the radiological release criteria stated in Section 3 of the FSS Plan [Reference 4]. The PSS Plan [Reference 4] described the process for survey preparation, survey design, data collection, data evaluation, and documentation of survey results.

3.1 Release Criteria The NRC-approved screening criteria for the ROC are listed in Table 3-1 for building surfaces. The approved DP [Reference 2] provides a list of ROC for use during implementation of the FSS Plan

[Reference 4]. Table 3-1 lists those ROC along with the approved release criteria originating in NUREG-1757 Consolidated Decommissioning Guidance [Reference 6], Appendix B. The release criteria listed below serve as Derived Concentration Guideline Level (DCGL) input parameters for the FSS calculations.

The classification of an area is based on characterization measurements and historical use of the area. Areas that have no reasonable potential for residual contamination because there was no known impact from site operations are classified as non-impacted areas. Non-impacted areas are not required to be surveyed beyond what is completed as a part of site characterization to confirm the area's non-impacted classification.

Areas that may contain residual radioactivity from licensed activities are considered impacted areas. Based on the levels of residual radioactivity present, impacted areas are further divided into Class I, Class 2, or Class 3 designations. Class I areas have the greatest potential for residual activity, while Class 3 areas have the least potential for residual contamination. Each classification will typically be bounded by areas classified one step lower to provide a buffer zone around the higher class. Exceptions occur when an area is surrounded by a significant physical barrier that would make transport of residual activity unlikely from one area to the adjacent area. In such cases, each area will be classified solely on its own merit using the most reliable information available.

Table 3-2 lists the survey units and classification for the areas of the facility included in the FSS Plan

All survey locations within survey unit 006 were biased survey locations.

3.2.1 Sample and Location Identification Measurement and sampling locations were plotted using Visual Sample Plan and numbered sequentially using a two digit number, e.g., 01, 02, 03, and 04.

3,3 Types and Methods of Surveys Survey measurements and sample collection were performed by personnel trained and qualified in accordance with the FSS Plan [Reference 4]. FSS measurements included surface scans, direct surface measurements, removable radionuclide measurements (beta and tritium), and gamma spectroscopy of volumetric material samples. Off-site laboratory facilities were used for gamma spectroscopy.

3.3.1 Scan Surveys Scanning was performed in order to locate small areas of residual activity above the investigation level.

Structures receive scan surveys, direct measurements and, when necessary, volumetric sampling. The percent of scan measurement coverage was based on the survey unit classification and was provided in Table 3-4 of the approved FSS Plan [Reference 4].

3.3.2 Two-Stage Scanning Method The two-stage scanning method was one where a surveyor begins the scan at a pre-determined speed, e.g.

10-cm per second, until they detect an elevated count rate. At such time, they return to a location immediately before the elevated detection and repeat the scan at a slower rate to determine the maximum count rate in the area. When the count rate returned to expected levels, the scan speed was returned to normal. This method relies on the ability of the surveyor to reliably detect elevated count rates. The

'Surveyor Efficiency' (p) is detailed in NUREG-1507, Minimnun Detectable Concentrations With Typical Radiation Survey Instrumentsfor Various Field Conditions [Reference 7]. A variable accounting for this efficiency (a value from 0.5 to 0.75) is included in the formulae used in the MARSSIM [Reference 5].

Lower values for p increase the Minimum Detectable Concentration for Scanning (MDCs.....) indicating a smaller probability of detecting elevated count rates. The MDCsc... equations used throughout this project assumed a value for p of 0.5. All scans performed in support of the FSS used the two-stage scan method to assure residual radioactive material is sufficiently quantified.

Blotcky Reactor Facility Exce/Ience--E ey po~ec Ever./day Final Status Survey Report 3.3.3 Beta-gamma Surface Scans Surface scans for beta-gamma activity on structures and selected systems were performed at a scan rate capable of meeting a pre-determined MDCs .... applicable to the survey unit classification. Surface scans had a probe to surface distance as close as practical, and did not exceed I -cm ('1/2/ inch). The MDCscan for all areas was no greater than 50 percent of the applicable DCGL. Minimum scan coverage is detailed in Table 3-3 by classification.

Table 3-3 Minimum Scan Coverage Classification Required Minimum Scan Coverage Class 1 100% of accessible areas Class 2 >10% of accessible areas Class 3 Judgmental, but generally a -in2 area around each data location 3.3.4 Direct Measurements Direct measurements were performed to detect surface activity levels. Direct measurements were conducted by placing the detector on or very near the surface to be measured and acquiring data over a pre-determined count time. A six (6) second count time was used for direct surface measurements and provided detection levels well below the release criteria. Direct measurements could have been collected anywhere within the grid block, but were generally collected in the center.

3.3.5 Exposure Rate Gamma exposure rate measurements were taken at each floor location approximately 1-m from the surface.

3.3.6 Removable Activity Removable contamination surveys, while not required as part of the MARSSLM [Reference 5], were collected to assess the removable activity fraction for selected structural and system surfaces. Wipe samples comprised 100-cm 2 of surface area. Wipe samples were analyzed on-site utilizing a wipe sample counter.

3.3.7 LSC Analysis All direct measurement survey locations had a removable activity wipe sample collected for tritium and C-14 analysis on-site using a liquid scintillation counter (LSC). Each 100 cm2 wipe sample was collected on dry wipe media, placed into a counting vial with 5 mL of Ultima GoldTM scintillation cocktail, and counted for 6 seconds.

3.3.8 Volumetric Samples Volumetric samples were analyzed at a qualified off-site laboratory by appropriate analytical methods for the radionuclides of concern applicable to thle subject area. Sample results where only one radionuclide had a result greater than the Minimum Detectable Concentration (MDC) were evaluated by direct comparison of the result against the appropriate release criteria. Samples with multiple radionuclides greater than MDC were evaluated using the sum of the fractions (SOF) calculation where the SOF value must be less than 1.

Sample preparation was performed by the off-site laboratory. Separate containers were used for each sample and each sample was tracked through the analysis process using a chain-of-custody record.

3.4 Survey Instrumentation Instruments were selected that provided an adequate response to ROC and were capable of having an MDC less than 50 percent of the applicable release criteria for the survey. MDC was calculated for each model using formulae contained in MARSSIM [Reference 5] and shown in Section 5.2.3. MARSSIM [Reference 5] contains the most current guidance on recommended methods of calculating survey instrument MDC.

The background rate and detector efficiency used in the MDC are averages calculated from the daily

NorthStar maintains original instrument calibration data and certificates for the calibration sources at the calibration laboratory and provided copies to file on-site. Appendix B provides the calibration records for the instruments used.

3.4.2 Pre-Operational Checks All background readings for counting instruments were conducted daily during instrument use. Any instrument that used a battery had a daily battery check performed before instrument operation. An initial source response to an appropriate on-site check source, as determined by a comparison to calibration information, was obtained prior to the instrument being placed in service for the project.

Each day an instrument was used, the instrument received an operational check that consisted of a background reading and a count of a known check source with the detector in contact with the source in its

Alan J. Blotcky Reactor Facility Eelnce--Every troject E, ydveda Final Status Survey Report holder to provide a consistent source to detector distance. This information was recorded on a Daily Source Check Log form. All ESS was completed while the instruments were within their 1 year calibration, thus no recalibrations were required.

3.4.3 Instrument Efficiency The efficiency of the detection capabilities for each applicable instrument was calculated using the following formula:

(C,,- C)

S Instrument Efficiency (El)

Where:

Cs=measured source count in cpm Cb = measured background count in cpm S = 2 pi source activity value in dpm Total Instrument Efficiency (Et)

Where:

Ei= instrument efficiency E*= surface efficiency (0.5 for beta emitters >400 keY f3i....)

The total instrument efficiency (Er) is a product of the instrument efficiency (Es) and the surface efficiency (Es) and is used to convert the raw instrument counts into the standardized unit of dpm. The surface efficiency utilized follows the recommendations in ISO 7503-1, Evaluation of Surface Contamination, 1988

[Reference 8], which makes recommendations for default surface efficiencies. A surface efficiency of 0.5 is recommended for beta emitters with maximum energies greater than 400 kiloelectronvolts (keV) as per NUREG-1 507 [Reference 7]; therefore, the surface efficiency used for the FSS was 0.5 based on a weighted maximum beta energy of 1496.87 keV. Table 3-5 shows the weighted maximum energy based on characterization data in the AJBlotcky Reactor Facility CharacterizationReport [Reference 9].

The MDC is the concentration of radioactivity that an instrument can be expected to detect at a 95 percent confidence level. For instruments performing direct and/or scan measurements, the MDC goal was 10 to 50 percent of the applicable release criteria. The MDC goals were met for the FSS instruments, and information used to calculate the MDC for instrumentation used during the FSS was documented on the radiation survey form.

Alan J.,lotcky RatrFclt Final Status Survey Report For static (direct) surface measurements, with conventional detectors, the MDC was calculated using the formula:

MDC (DPM/100 cm2) [: +32 1(bT,.E)Q T)

Where:

Rh = background count rate (cpm)

/Tb background count time (mai)

T..= sample count time (min)

E, = total instrument efficiency (MARSSIM [Reference 5] Section 6.6.1)

The MDCsca,, for beta-gamma measurements was calculated by determining the minimum detectable count rate (MDCR). The MDCR was determined by first detennining the minimum detectable net source counts using Formula 6-8 in the MARSSIM [Reference 5] as below.

Minimum number of detectable source counts: s, d'*.T-7 Where:

d'= value from MARSSIM [Reference 5] Table 6.5 for applicable true and false positive rates (1.38 for a true positive proportion of 0.95 and a false positive proportion of 0.60) bi= number of background counts in a given time interval The MDCR is calculated from Formula 6-9 in the MARSSIM [Reference 5]:

Minimum detectable count rate: MDCR = si 2--

Where:

[Reference 7]. It is a percentage estimate of the likelihood a surveyor will reliably detect an elevated count rate.

Material specific background, i.e., naturally occurring radioactive materials in brick and concrete, was not subtracted from the gross results.

4.1 Survey Unit 001 -Reactor Pit The reactor pit was surveyed as one Class 1 survey unit. The lower portion of the tank liner and gunite was impacted by the neutron flux of the reactor. These impacted portions were removed and disposed as LLRW.

Core samples collected during the remediation indicated the presence of low levels radioactivity within some portions of the reactor pit gunite, steel liner, and/or concrete. The relative shift for the survey unit was therefore conservatively assumed to be 1, which requires a minimum of 24 valid static survey results to meet MARSSIM [Reference 51 requirements. The survey consisted of 33 static locations on the floor and walls of the pit chosen using a triangular grid with a random start location. Some residual radioactive materials remain in volumetric concentrations. Table 4-1 provides a summary of the surface contamination results.

The four radionuclides listed in Table 4-2 were detected above the MDC. All results in the concrete were below the release criteria.

Consequently this area was defined as a Class 1 survey unit. Characterization data and routine surveys performed during D&D activities did not indicate the presence of any radioactive contamination, therefore the relative shift of the area was set at 3 which requires a minimum of 11 valid static survey results to meet MARSSIM [Reference 5] requirements. Fifteen (15) static survey locations were identified using a triangular grid and a random start location. The area was surveyed for tritium, total beta, and removable beta with the data results summarized in Table 4-4 below.

5.0 CONCLUSION

S Based on the results described in Section 4.0 of this FSS report, the facility meets the requirements for unrestricted release specified in the FSS Plan [Reference 4] and the DP [Reference 2].

All total beta measurements were less than the MDC. The maximum result for total beta activity was located on the floor in Room 526 with a result of 1,284 DPM/1 00 cm 2. The average beta activity for each survey unit was less than 500 DPM/1 00 cm2.

The average level of residual radioactive materials on building surfaces is 11 percent of the screening criteria, which would theoretically result in a dose to the average member of the critical group, i.e. a member of the general public, of 2.3 mrem TEDE per year. The average SOF for the remaining reactor pit concrete is 0.26 which would theoretically result in a dose to a member of the general public, of 6.5 mrem TEDE per year.

~AnaIyticaI Greensburg, PA 15601 www.psce)abs.com (724)850-5600 PROJECT NARRATIVE Project: AJ Blotcky Pace Project No.: 30161079 Date: November 16, 2015 Samples received identified as "steel" samples by the client could not be processed to match the exact calibration geometry for gamma spectroscopy analysis. Each steel sample received was placed in the bottom of a 4-ounce can. None of the steel samples were of sufficient size as to fill the entire volume of the cans used. Reported gamma-spec results for the steel samples should be construed as over-estimated based on differences between the sample configuration and the calibration source used for analysis.

Reported results for these samples are likely over-estimated by approximately 25%.

The LCS recovery associated with the Fe-55 analysis of samples 30161079001, 30161079006, 30161079009, and 30161079027 was low and outside of Pace's default acceptance criteria for LOS recovery. The recovery was 68%. Both the LCSD and MS recoveries were acceptable. Data is being reported as possibly biased low.

WORKORDER QUALIFIERS WO: 30161079

[1] Samples received identified as "steel" samples by the client could not be processed to match the exact calibration geometry for gamma spectroscopy analysis. Each steel sample received was placed in the bottom of a 4-ounce can.

None of the steel samples were of sufficient size as to fill the entire volume of the cans used. Reported gamma-spec results for the steel samples should be construed as over-estimated based on differences between the sample configuration and the calibration source used for analysis. Reported results for these samples are likely over-estimated by approximately 25%.

[2] The LCS recovery associated with the Fe-55 analysis of samples 30161079001, 30161079006, 30161079009, and 30161079027 was low and outside of Pace's default acceptance criteria for LCS recovery. The recovery was 68%. Both the LCSD and MS recoveries were acceptable. Data is being reported as possibly biased low.

ANALYTE QUALIFIERS N2 The lab does not hold TNI accreditation for this parameter.

ANALYTE QUALIFIERS lc Chemical recovery is determined gravimetrically for Ni-63 analysis. Sample 30163346007 had a chemical recovery of 687.2%. During the analysis, it was noted that a white precipitate formed in addition to the expected Ni-DMG precipitate per the method. Cobalt can precipitate with nickel in the presence of DMG and may be the cause for the high chemical yield. To minimize the bias caused by the elevated yield on the final result, Pace has applied the maximum recovery of 130% to sample 30163346007 Ni-63 results, however, it should be noted that the results may still be biased low depending on the actual contribution of the unknown contaminant. An attempt will be made to re-prepare and re-analyze the sample using a lesser aliquot.

N2 The lab does not hold TNI accreditation for this parameter.

SUMMARY

The Alan J. Blotcky Reactor Facility (AJBRF) is located in the Omaha Veterans Affairs Medical Center (VAMC) in the city of Omaha, Nebraska. The Omaha VAMC is located in a commercial area within the city limits, and the reactor facility is housed in the southwest corner basement of Building One. The reactor facility contained a low-power Mark l Training, Research, Isotopes, General Atomics (TRIGA) nuclear reactor, which was operated as a source for neutron activation analysis of biological samples and for hot atom chemistry research. Additionally, from 1989 to 2001, the reactor was used for training Fort Calhoun Station nuclear power reactor operators.

The AJBRF initial Operating License No. R-57 was issued on June 26, 1959. The most notable license amendment, Amendment 9, was issued on April 12, 1991, to allow for operation of the reactor at steady-state power levels up to a maximum of 20 kilowatts (kW) thermal and for the installation of a microprocessor-based neutron monitoring system. The most recent license renewal was issued as Amendment 12 [Reference 1] approving the Alan J. Blotcky Reactor Facility Decommissioning Plan

[Reference 2].

The facility ceased operation of the reactor on November 5, 2001. The fuel elements were subsequently removed and shipped to the U.S. Geological Survey TRIGA reactor in Denver, Colorado in June 2002.

The facility underwent decommissioning activities from July 2015 through November 2015 followed by Final Status Surveys (ESS) using calibrated instruments to measure total (static) beta activity and to perform radiological scan measurements. Smears were also collected for tritium and beta at every measurement location plus several items based on professional judgment. A total of 173 measurement locations and twelve (12) concrete sampling locations were used to assess the final radiological status of the facility.

All total beta measurements were less than the release criteria for the most restrictive isotope (Cobalt 60 at 7,100 disintegrations per minute per 100 square centimeters [DPM/100 cm 2]) and all scan measurements were less than the investigation levels. The maximum result surveyed on a building surface was 1,284 DPM/100 cm2 on the floor in Room 526.

Nine concrete samples had detectable radionuclides at very low levels with the most elevated result being for Europium-152 at 3.66 picocuries per gram (pCi/g) which is approximately 53 percent of the screening level criteria (6.9 pCi/g).

Based on the results described in Section 4.0 of this FSS report, the AJBRF meets the requirements for unrestricted release specified in 10 Code of FederalRegulations 20, Subpart E, Radiological Criteriafor License Termination [Reference 3], by meeting the requirements of the NRC approved AJBRF-FSSP-01 FinalStatus Survey Plan [Reference 4] and the DP [Reference 2].

2.0 INTRODUCTION

2.1 Purpose and Objective This report describes the purpose, scope, and technical approach used during the FSS of the AJB RF.

The purpose of the FSS activities is to demonstrate that the radiological conditions at the facility satisfy the release criteria and the U.S. Nuclear Regulatory Commission (NRC) license may be terminated. For the purpose of this demonstration, each survey unit is independently evaluated. The objective of the survey is to demonstrate at a 95 percent minimum level of confidence that the radiological release conditions have been met.

2.2 Project Background The AJBRF is located in the Omaha VAMC in the city of Omaha, Nebraska. The Omaha VAMC is located in a commercial area within the city limits, and the reactor facility is housed in the southwest corner basement of Building One. The reactor facility contained a low-power Mark I TRIGA nuclear reactor, which was operated as a source for neutron activation analysis of biological samples and for hot atom chemistry research. Additionally, from 1989 to 2001, the reactor was used for training Fort Calhoun Station nuclear power reactor operators.

The AJBRF initial Operating License No. R-57 was issued on June 26, 1959. The most notable license amendment, Amendment 9, was issued on April 12, 1991, to allow for operation of the reactor at steady-state power levels up to a maximum of 20 kW thermal and for the installation of a microprocessor-based neutron monitoring system. The most recent license renewal was issued as Amendment II on August 5, 2002, authorizing operation for an additional 20 years (VA, 2002a).

The facility ceased operation of the reactor on November 5, 2001. The reactor core, defueled in June 2002, was located in a reactor tank that was 21 feet deep and 6.5 feet in diameter, located below grade in Room 526. The tank contained approximately 5,000 gallons of demineralized water. The fuel elements were removed and shipped to the U.S. Geological Survey TRIGA reactor in Denver, Colorado in June 2002.

There was no history of major accidents or spills.

2.3 Decommissioning Activities During 2015, the facility underwent full decontamination and decommissioning (D&D) activities to support the termination of NRC License No. R-57. D&D activities were conducted by NorthStar Federal Services, Inc. (NorthStar) in accordance with the NRC-approved DP [Reference 2]. The NorthStar team began project planning in May 2015 with the development of all plans and procedures needed to perform the decommissioning activities. Following owner review and approval of the plans and procedures, the team mobilized personnel to prepare the site for D&D activities. Radiological D&D activities began in early July 2015 and were conducted through November 2015.

The D&D activities consisted of disposing or free releasing miscellaneous equipment from the facility; removing the control rods, dummy fuel rods, drives, bridge, and reactor assembly from the reactor tank; draining the tank water; and removing the activated sections of reactor tank steel liner and gunite. The filtration system, cooling compressor, and associated piping were removed and disposed of as low-level radioactive waste (LLRW). After all items were removed from the pool, the water was analyzed with the results less 10 CFR 20 [Reference 3] Appendix B Table 2 Column 3 concentration levels for releases to sewers. The water was released to the sanitary sewer.

Following removal of reactor internals and poo1 water, a 12 inch long by 3 inch diameter concrete core drill was advanced through twelve (12) locations in the sidewalls and the reactor pit floor to collect samples for analysis to investigate the depth of activation in the reactor pit. The core drill was advanced horizontally through the gunite, steel, and concrete at the core mid plane and at one location vertically downward at the axial centerline of the reactor tank. Additional cores were advanced at elevations up to six feet above the reactor pit floor. Surface radiological measurements at the 6 foot elevation were background. Each core

rAlan Excellence--Every project. Every day.

J. Blotcky Reactor Facility Final Status Survey Report was then segmented by layer, i.e., gunite, steel, and concrete. The gunite layer ranged from approximately 2 to 4 inches thick, the steel liner was from 1/4A to 1/2/inch thick, and the concrete was approximately 9 inches thick. Samples were sent to an off-site radioanalytical laboratory for analysis of the Radionuclides of Concern (ROCs) listed in Table 3-1 below, including analysis of the hard-to-detect radionuclides Tritium, Carbon-14, lron-55, and Nickel-63.

The analysis of the cores revealed that the lower six-foot of the reactor pit required remediation. The activated gunite lining was removed from the reactor tank walls and disposed of as LLRW. An oxyacetylene torch was used to cut away the steel liner located in the floor and lower 6 feet of the reactor pit including portions of the steel liner where sample results indicated concentrations less than the release criteria. All the steel was sized and packaged as LLRW. Each of the core samples was collected in accordance with the FSS Plan [Reference 4] in order to utilize relevant portions of the sample data for FSS.

Following the removal of all radiologically impacted materials, the FSS was conducted in the facility using the methodology described in the following section.

t* Alan J. Blotcky Reactor Facility Exce/ferce--Ev ry proiect. Evei day. Final Status Survey Report 3.0 FINAL STATUS SURVEY METHODOLOGY The ESS provided data and information to demonstrate that the facility complies with the NRC annual dose limit criteria of 25-millirem (mrem) per year Total Effective Dose Estimate (TEDE) the radiological criteria listed in the NRC approved DP [Reference 21.

The FSS was designed in accordance with the NRC's NUREG-15 75, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) [Reference 5], and the NRC-approved FSS Plan [Reference 4], in order to demonstrate that the facility complies with the radiological release criteria stated in Section 3 of the FSS Plan [Reference 4]. The PSS Plan [Reference 4] described the process for survey preparation, survey design, data collection, data evaluation, and documentation of survey results.

3.1 Release Criteria The NRC-approved screening criteria for the ROC are listed in Table 3-1 for building surfaces. The approved DP [Reference 2] provides a list of ROC for use during implementation of the FSS Plan

The classification of an area is based on characterization measurements and historical use of the area. Areas that have no reasonable potential for residual contamination because there was no known impact from site operations are classified as non-impacted areas. Non-impacted areas are not required to be surveyed beyond what is completed as a part of site characterization to confirm the area's non-impacted classification.

Areas that may contain residual radioactivity from licensed activities are considered impacted areas. Based on the levels of residual radioactivity present, impacted areas are further divided into Class I, Class 2, or Class 3 designations. Class I areas have the greatest potential for residual activity, while Class 3 areas have the least potential for residual contamination. Each classification will typically be bounded by areas classified one step lower to provide a buffer zone around the higher class. Exceptions occur when an area is surrounded by a significant physical barrier that would make transport of residual activity unlikely from one area to the adjacent area. In such cases, each area will be classified solely on its own merit using the most reliable information available.

Table 3-2 lists the survey units and classification for the areas of the facility included in the FSS Plan

All survey locations within survey unit 006 were biased survey locations.

3.2.1 Sample and Location Identification Measurement and sampling locations were plotted using Visual Sample Plan and numbered sequentially using a two digit number, e.g., 01, 02, 03, and 04.

3,3 Types and Methods of Surveys Survey measurements and sample collection were performed by personnel trained and qualified in accordance with the FSS Plan [Reference 4]. FSS measurements included surface scans, direct surface measurements, removable radionuclide measurements (beta and tritium), and gamma spectroscopy of volumetric material samples. Off-site laboratory facilities were used for gamma spectroscopy.

3.3.1 Scan Surveys Scanning was performed in order to locate small areas of residual activity above the investigation level.

Structures receive scan surveys, direct measurements and, when necessary, volumetric sampling. The percent of scan measurement coverage was based on the survey unit classification and was provided in Table 3-4 of the approved FSS Plan [Reference 4].

3.3.2 Two-Stage Scanning Method The two-stage scanning method was one where a surveyor begins the scan at a pre-determined speed, e.g.

10-cm per second, until they detect an elevated count rate. At such time, they return to a location immediately before the elevated detection and repeat the scan at a slower rate to determine the maximum count rate in the area. When the count rate returned to expected levels, the scan speed was returned to normal. This method relies on the ability of the surveyor to reliably detect elevated count rates. The

'Surveyor Efficiency' (p) is detailed in NUREG-1507, Minimnun Detectable Concentrations With Typical Radiation Survey Instrumentsfor Various Field Conditions [Reference 7]. A variable accounting for this efficiency (a value from 0.5 to 0.75) is included in the formulae used in the MARSSIM [Reference 5].

Lower values for p increase the Minimum Detectable Concentration for Scanning (MDCs.....) indicating a smaller probability of detecting elevated count rates. The MDCsc... equations used throughout this project assumed a value for p of 0.5. All scans performed in support of the FSS used the two-stage scan method to assure residual radioactive material is sufficiently quantified.

Blotcky Reactor Facility Exce/Ience--E ey po~ec Ever./day Final Status Survey Report 3.3.3 Beta-gamma Surface Scans Surface scans for beta-gamma activity on structures and selected systems were performed at a scan rate capable of meeting a pre-determined MDCs .... applicable to the survey unit classification. Surface scans had a probe to surface distance as close as practical, and did not exceed I -cm ('1/2/ inch). The MDCscan for all areas was no greater than 50 percent of the applicable DCGL. Minimum scan coverage is detailed in Table 3-3 by classification.

Table 3-3 Minimum Scan Coverage Classification Required Minimum Scan Coverage Class 1 100% of accessible areas Class 2 >10% of accessible areas Class 3 Judgmental, but generally a -in2 area around each data location 3.3.4 Direct Measurements Direct measurements were performed to detect surface activity levels. Direct measurements were conducted by placing the detector on or very near the surface to be measured and acquiring data over a pre-determined count time. A six (6) second count time was used for direct surface measurements and provided detection levels well below the release criteria. Direct measurements could have been collected anywhere within the grid block, but were generally collected in the center.

3.3.5 Exposure Rate Gamma exposure rate measurements were taken at each floor location approximately 1-m from the surface.

3.3.6 Removable Activity Removable contamination surveys, while not required as part of the MARSSLM [Reference 5], were collected to assess the removable activity fraction for selected structural and system surfaces. Wipe samples comprised 100-cm 2 of surface area. Wipe samples were analyzed on-site utilizing a wipe sample counter.

3.3.7 LSC Analysis All direct measurement survey locations had a removable activity wipe sample collected for tritium and C-14 analysis on-site using a liquid scintillation counter (LSC). Each 100 cm2 wipe sample was collected on dry wipe media, placed into a counting vial with 5 mL of Ultima GoldTM scintillation cocktail, and counted for 6 seconds.

3.3.8 Volumetric Samples Volumetric samples were analyzed at a qualified off-site laboratory by appropriate analytical methods for the radionuclides of concern applicable to thle subject area. Sample results where only one radionuclide had a result greater than the Minimum Detectable Concentration (MDC) were evaluated by direct comparison of the result against the appropriate release criteria. Samples with multiple radionuclides greater than MDC were evaluated using the sum of the fractions (SOF) calculation where the SOF value must be less than 1.

Sample preparation was performed by the off-site laboratory. Separate containers were used for each sample and each sample was tracked through the analysis process using a chain-of-custody record.

3.4 Survey Instrumentation Instruments were selected that provided an adequate response to ROC and were capable of having an MDC less than 50 percent of the applicable release criteria for the survey. MDC was calculated for each model using formulae contained in MARSSIM [Reference 5] and shown in Section 5.2.3. MARSSIM [Reference 5] contains the most current guidance on recommended methods of calculating survey instrument MDC.

The background rate and detector efficiency used in the MDC are averages calculated from the daily

Table 3--4 shows the instrument types selected and summarizes the typical observed background counts in counts per minute (cpm), typical observed detector efficiency, and a typical observed MDC in DPM/100 cm 2 for each instrument model. Other objectives in selecting instruments included special features such as digital displays to provide a more accurate reading than conventional analog displays.

NorthStar maintains original instrument calibration data and certificates for the calibration sources at the calibration laboratory and provided copies to file on-site. Appendix B provides the calibration records for the instruments used.

3.4.2 Pre-Operational Checks All background readings for counting instruments were conducted daily during instrument use. Any instrument that used a battery had a daily battery check performed before instrument operation. An initial source response to an appropriate on-site check source, as determined by a comparison to calibration information, was obtained prior to the instrument being placed in service for the project.

Each day an instrument was used, the instrument received an operational check that consisted of a background reading and a count of a known check source with the detector in contact with the source in its

Alan J. Blotcky Reactor Facility Eelnce--Every troject E, ydveda Final Status Survey Report holder to provide a consistent source to detector distance. This information was recorded on a Daily Source Check Log form. All ESS was completed while the instruments were within their 1 year calibration, thus no recalibrations were required.

3.4.3 Instrument Efficiency The efficiency of the detection capabilities for each applicable instrument was calculated using the following formula:

(C,,- C)

S Instrument Efficiency (El)

Where:

Cs=measured source count in cpm Cb = measured background count in cpm S = 2 pi source activity value in dpm Total Instrument Efficiency (Et)

Where:

Ei= instrument efficiency E*= surface efficiency (0.5 for beta emitters >400 keY f3i....)

The total instrument efficiency (Er) is a product of the instrument efficiency (Es) and the surface efficiency (Es) and is used to convert the raw instrument counts into the standardized unit of dpm. The surface efficiency utilized follows the recommendations in ISO 7503-1, Evaluation of Surface Contamination, 1988

[Reference 8], which makes recommendations for default surface efficiencies. A surface efficiency of 0.5 is recommended for beta emitters with maximum energies greater than 400 kiloelectronvolts (keV) as per NUREG-1 507 [Reference 7]; therefore, the surface efficiency used for the FSS was 0.5 based on a weighted maximum beta energy of 1496.87 keV. Table 3-5 shows the weighted maximum energy based on characterization data in the AJBlotcky Reactor Facility CharacterizationReport [Reference 9].

The MDC is the concentration of radioactivity that an instrument can be expected to detect at a 95 percent confidence level. For instruments performing direct and/or scan measurements, the MDC goal was 10 to 50 percent of the applicable release criteria. The MDC goals were met for the FSS instruments, and information used to calculate the MDC for instrumentation used during the FSS was documented on the radiation survey form.

Alan J.,lotcky RatrFclt Final Status Survey Report For static (direct) surface measurements, with conventional detectors, the MDC was calculated using the formula:

Where:

/Tb background count time (mai)

T..= sample count time (min)

E, = total instrument efficiency (MARSSIM [Reference 5] Section 6.6.1)

The MDCsca,, for beta-gamma measurements was calculated by determining the minimum detectable count rate (MDCR). The MDCR was determined by first detennining the minimum detectable net source counts using Formula 6-8 in the MARSSIM [Reference 5] as below.

Minimum number of detectable source counts: s, d'*.T-7 Where:

Where:

[Reference 7]. It is a percentage estimate of the likelihood a surveyor will reliably detect an elevated count rate.

Excellence--Every project. Everj day, Final Status Survey Report 4.0 FINAL STATUS SURVEY RESULTS The following sections describe the FSS survey techniques employed in each survey unit and are organized by survey area, i.e., room or reactor pit. The data collected in the FSS are summarized in each section, with each radiological survey record provided in Appendix B. Data results were calculated with instrument background subtraction only. Material specific background, i.e., naturally occurring radioactive materials in brick and concrete, was not subtracted from the gross results.

4.1 Survey Unit 001 -Reactor Pit The reactor pit was surveyed as one Class 1 survey unit. The lower portion of the tank liner and gunite was impacted by the neutron flux of the reactor. These impacted portions were removed and disposed as LLRW.

Core samples collected during the remediation indicated the presence of low levels radioactivity within some portions of the reactor pit gunite, steel liner, and/or concrete. The relative shift for the survey unit was therefore conservatively assumed to be 1, which requires a minimum of 24 valid static survey results to meet MARSSIM [Reference 51 requirements. The survey consisted of 33 static locations on the floor and walls of the pit chosen using a triangular grid with a random start location. Some residual radioactive materials remain in volumetric concentrations. Table 4-1 provides a summary of the surface contamination results.

The four radionuclides listed in Table 4-2 were detected above the MDC. All results in the concrete were below the release criteria.

5.0 CONCLUSION

S Based on the results described in Section 4.0 of this FSS report, the facility meets the requirements for unrestricted release specified in the FSS Plan [Reference 4] and the DP [Reference 2].

All total beta measurements were less than the MDC. The maximum result for total beta activity was located on the floor in Room 526 with a result of 1,284 DPM/1 00 cm 2. The average beta activity for each survey unit was less than 500 DPM/1 00 cm2.

The average level of residual radioactive materials on building surfaces is 11 percent of the screening criteria, which would theoretically result in a dose to the average member of the critical group, i.e. a member of the general public, of 2.3 mrem TEDE per year. The average SOF for the remaining reactor pit concrete is 0.26 which would theoretically result in a dose to a member of the general public, of 6.5 mrem TEDE per year.

~AnaIyticaI Greensburg, PA 15601 www.psce)abs.com (724)850-5600 PROJECT NARRATIVE Project: AJ Blotcky Pace Project No.: 30161079 Date: November 16, 2015 Samples received identified as "steel" samples by the client could not be processed to match the exact calibration geometry for gamma spectroscopy analysis. Each steel sample received was placed in the bottom of a 4-ounce can. None of the steel samples were of sufficient size as to fill the entire volume of the cans used. Reported gamma-spec results for the steel samples should be construed as over-estimated based on differences between the sample configuration and the calibration source used for analysis.

Reported results for these samples are likely over-estimated by approximately 25%.

The LCS recovery associated with the Fe-55 analysis of samples 30161079001, 30161079006, 30161079009, and 30161079027 was low and outside of Pace's default acceptance criteria for LOS recovery. The recovery was 68%. Both the LCSD and MS recoveries were acceptable. Data is being reported as possibly biased low.

WORKORDER QUALIFIERS WO: 30161079

[1] Samples received identified as "steel" samples by the client could not be processed to match the exact calibration geometry for gamma spectroscopy analysis. Each steel sample received was placed in the bottom of a 4-ounce can.

None of the steel samples were of sufficient size as to fill the entire volume of the cans used. Reported gamma-spec results for the steel samples should be construed as over-estimated based on differences between the sample configuration and the calibration source used for analysis. Reported results for these samples are likely over-estimated by approximately 25%.

[2] The LCS recovery associated with the Fe-55 analysis of samples 30161079001, 30161079006, 30161079009, and 30161079027 was low and outside of Pace's default acceptance criteria for LCS recovery. The recovery was 68%. Both the LCSD and MS recoveries were acceptable. Data is being reported as possibly biased low.

ANALYTE QUALIFIERS N2 The lab does not hold TNI accreditation for this parameter.

Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.

TN! - The NELAC Institute.

ANALYTE QUALIFIERS lc Chemical recovery is determined gravimetrically for Ni-63 analysis. Sample 30163346007 had a chemical recovery of 687.2%. During the analysis, it was noted that a white precipitate formed in addition to the expected Ni-DMG precipitate per the method. Cobalt can precipitate with nickel in the presence of DMG and may be the cause for the high chemical yield. To minimize the bias caused by the elevated yield on the final result, Pace has applied the maximum recovery of 130% to sample 30163346007 Ni-63 results, however, it should be noted that the results may still be biased low depending on the actual contribution of the unknown contaminant. An attempt will be made to re-prepare and re-analyze the sample using a lesser aliquot.

N2 The lab does not hold TNI accreditation for this parameter.
