SUMMARY

Operation of the Alan J. Blotcky reactor facility was permanently shut down in November 2001 following a decision to cease operations and decommission the reactor. The ftiel was shipped to a similar reactor in Colorado in June 2002. Duratek was contracted to perform a characterization of the facility and surrounding environs so that the Department of Veterans Affairs (DVA) could develop a detailed decommissioning plan.The characterization included performing a Historical Site Assessment (HSA), preparing plans, performing a comprehensive radiation survey, performing activation analysis calculations of surrounding materials, and sampling for lead and asbestos. The HSA involved a site walk-down, interviews with current and former employees, and a review of facility records. Information obtained during the HSA was included in the characterization plan, the survey packages, and this report. APPENDIX A to this report lists the historical documents reviewed and notes regarding the document content that could be important to the radiological status of the facility.In addition to the Characterization Survey Plan, a Site Safety and Health Plan, Quality Assurance Project Plan, and Project Management Plan were written and approved to control the characterization efforts. The plans were developed by Duratek staff at the Commercial Services office in Kingston, Tennessee, and reviewed and approved for use at the project site. The characterization of the facility was performed according to these plans and the procedures referenced in the plans. Data quality objectives (DQOs) stated in the plans were achieved in the characterization survey.Once the planning phase was completed, the Duratek survey team mobilized to the site.Training was completed on the project plans for the Duratek personnel, and the equipment was set up to begin surveys. Instrumentation included an on-site gamma spectroscopy system; data loggers capable of interfacing with numerous probes including thin window Geiger-Muller (GM) detectors, gas flow proportional detectors, and Nal (Tl)exposure rate detectors; and an Eberline RO-7 with a high range detector for pool components. Nine survey packages describing rooms and areas of the reactor facility and site surfaces, structures, and environs were developed. Each survey package contained detailed instructions, drawings, and location codes to collect the 3,100 measurements and samples that were analyzed for the characterization. The measurements and samples collected for the radiological characterization survey consisted of direct beta measurements; direct alpha measurements; smear samples for alpha and beta contamination; smear samples for removable tritium; exposure rate measurements; and soil, sediment, and water samples analyzed by gamma spectroscopy. Soil borings were made by HDR Engineering to evaluate the groundwater flow and direction and to analyze the soil adjacent to the reactor core for gamma emitting radionuclides. Three test wells were installed to depths between 100 and 131 feet. Four additional borings (without installation of wells) were made to a depth of 36 feet (approximately 10 feet below the bottom of the reactor). Eighty-eight soil samples for various depths from all seven borings were analyzed by gamma spectroscopy. None of Revision 0 8 of69 the samples showed activity other than naturally occurring radionuclides present at concentrations typical for US soils'.In addition to the soil borings, 30 surface soil and 30 subsurface soil samples were obtained during the characterization. None of the samples showed activity other than naturally occurring radionuclides. A sample of resin was obtained from the reactor coolant demineralizer and sent to Eberline Services Laboratory in Oak Ridge, Tennessee, for analysis of 10 CFR part 61 radionuclides and other radionuclides typical of reactor activation and fission products.The sample analysis identified the radionuclide mixture that could be used to establish derived concentration guideline levels (DCGLs) for the site decommissioning. DCGLs were developed to meet the intent of Subpart E, 10 CFR 20.1402, Radiological Criteria for Unrestricted Use. The DCGL for gross activity measurements equivalent to the 25 mrem annual total effective dose equivalent was calculated to be 27,000 dpmIlOO cm 2 for building surfaces and structures. The building surfaces (walls, floors, and overheads) are characterized to be relatively free of licensed materials and none of the measurements exceeded the calculated DCGL of 27,000 dpml1 OOcm 2.Table 1. I provides a summary of the areas and identifies measurements that exceeded 1000 dpm/100 cm 2 total beta contamination or 40 dpm/I00 cm 2 of removable beta contamination. 1000 dpmIlOO cm 2 was the highest minimum detectable activity (MDA) for fixed beta measurements. The required MDA for removable beta measurements was 100 dpm/I00 cm 2 , but actual measurement MDAs were less than 35 dpm/100 cm 2.All measurements of total alpha contamination were less than the 100 dpm/I00 cm 2 required MDA. The highest total alpha measurement was 79 dpm/100 cm 2.Activity of the drains and vents was evaluated, and the highest measurements are identified in Table 1.1. Bolded values are values that exceed the calculated DCGL of 27,000 dpm/lOO cm 2 for fixed measurements or 2,700 dpm/100 cm 2 for removable measurements (10% of the DCGL). The only survey areas that exceeded the calculated DCGL were: (1) the south lab hood in room SW2D and (2) Drain 3 in the south lab hood of room SW2D. Table 1.1 does not include the activity measurements of the reactor pool components. Reactor pool components and the concrete and stainless steel reactor pit are assumed to be above guideline values and will need to be disposed of as radioactive waste. The reactor pool components are discussed in Attachment 11 to this report, Materials Disposition Report.I Reference values for US soils are noted in NUREG-1501, Background as a Residual Radioactivity Criterion for Decommissioning. Draft Report, August 1994. Table 2.2 of NUREG 1501 lists the average concentration of background radionuclides in US soils as 1.0 pCi/g for uranium series radionuclides (range of 0.1 to 3.81 pCi/g) and an average of 1.0 pCi/g for thoriurn series radionuclides (range of 0.1 to 3.41 pCi/g).Revision 0 9 of 69 Fifteen field screen chemical tests and three scraping samples were taken to evaluate for the presence of lead in paint. Eight samples were taken to evaluate the presence of asbestos. Asbestos samples showed asbestos in the lab counters, fume hood panels, floor tiles, pipe insulation, and in the floor tile mastic adhesive. Paint samples from the three paint locations (beige paint from dumbwaiter frame, beige paint from the south stairwell door frame, and beige paint from the south east corner column) all showed measurable lead (from 0.066 to 1.068 % lead by weight). Two of these samples exceeded the limit of 0.5% lead by weight established in the Lead-Based Paint Poisoning Prevention Act of 1971, as amended by the Housing and Community Development Act of 1987. Both of the positive lead samples were taken on painted metal and typical of older metal primers.Revision 0 10 of 69 (h ((Table 1.1 Summary of Areas with Measurable Activi _Direct Alpha Survey Package Direct Beta Activity Activity Removable Activity H-3 (Area) (0/y dpm/100 cm 2) (a dpm/100 cm 2) (dpm/100 cm) (dpm/100 cm 2) Notes A0001 (Rooms 2A None None None None None& 2B)_A0002

Blotcky (AJB) reactor facility located within the Veterans Affairs Medical Center in the city of Omaha, Douglas County, Nebraska maintains United States Nuclear Regulatory Commission (U.S. NRC) Facility Operating License R-57. The reactor is housed in the basement of the southwest wing of the medical center building.This report describes the survey protocols used to characterize the AJB reactor facility.The characterization of the facility included rooms, ventilation systems, drainage systems, cooling systems, storage areas, the reactor structures, and outside areas. Figure 2.1 shows the location of the reactor within the VA Medical Center.The purpose of the characterization survey was to collect sufficient survey data to allow the Department of Veterans Affairs (DVA) to develop a detailed decommissioning plan.The characterization was completed by implementing plans and procedures developed for the project.2.1 Site Description The AJB reactor facility is located in the basement of the southwest wing of the medical center. The 11- story medical center research addition (Figure 2. 1) was erected in 1951. The medical center is built on the high point of a knoll. To the north is a county hospital, to the south a commercial district, to the west a residential area, and to the east a golf course. Omaha is situated on the west bank of the Missouri river; the river level at Omaha is normally about 965 ft above sea level. The rolling hills in and around Omaha rise to approximately 1300 ft above sea level.2.2 AJB Reactor General Description and Operational History Reactor Type The reactor is a Training, Research, Isotopes, General Atomics (TRIGA) MARK I reactor, owned by the U.S. Department of Veterans Affairs. Operated by the Omaha Veterans Affairs Medical Center, the reactor is licensed pursuant to 10 CFR Part 50 (Domestic Licensing of Production and Utilization Facilities) under Facility License R-57. The reactor is a pool-type facility that was previously fueled with standard TRIGA fuel elements enriched to less than 20% uranium-235 zirconium hydride. Fuel elements were removed in June 2002 and shipped to the United States Geological Survey (USGS) TRIGA reactor in Denver, Colorado.Revision 0 14 of 69 The below ground AJB TRIGA reactor contains a graphite-reflected fixed core resting on the bottom of a 20 foot steel, concrete, gunite, and epoxy coated tank.The surrounding earth and demineralized water within the tank provided the required shielding so that no special containment building was necessary.

Blotcky Reactor Facility Location VA Medical Center';1 *I/rV~;~ii flGA k .r,~' ' '1/ / 7/ 7-7/Revision 0 15 of 69 Reactor History Reactor construction began on January 8, 1959, when the core centerline 30-foot test auger boring was taken in the basement of the facility. Construction of the AJB reactor facility was completed on June 24, 1959, in conformity with: construction permit No. CPRR-36 the provisions of the Atomic Energy Act of 1954 and the regulations of the Atomic Energy Commission. The reactor was safely operated at 18 kW between June 1959 and April 12, 1991, and at 20 kW from April 12, 1991, to November 5, 2001. Total operational hours at the facility were usually between 1000 and 2000 hours annually. During the last 3 years of operation, the reactor operation was approximately 1000 kW-hrs. The lifetime total from 1959 through 2002 is approximately 515,000 kW-hrs.The AJB reactor was used to support nuclear medicine and research programs conducted at the medical center. Between 1959 and 1965 the reactor was funded as a national laboratory and employed approximately 30 people. The principle use of the reactor was for neutron activation of biological samples. Typical irradiation times were 3 minutes. Samples were irradiated in 5 ml vials. The vials were opened in the fume hood to allow the argon-41 (Ar-l) to vent to the atmosphere. 2.3 AJB Reactor Facility Structures, Components, and Systems The medical center building is constructed of brick and reinforced concrete, including the floors and ceiling, except that the walls between the rooms in the reactor area are of wood and plaster construction. Entrance to the reactor laboratory is normally through the door marked SW 2 (Figure 2.2). The area to the left of the access door serves as a health physics control point. Samples to be irradiated were typically prepared in either room SW 2C or SW 2E. Isotopes were stored in the isotope storage area SW 2F. The pneumatic transfer system is shown in Figure 2.2. Gamma counting of irradiated samples was performed in the area marked shield. Looking at various drawings, the room use sometimes changed; a list of the various room use noted on the drawings is provided.Room or Area Number Use SW I Lockers SW IA Restroom and Shower SW 2 Radioisotope Reactor Research Lab SW 2A Office Electron Microscope SW 2B Office Dark Room Clothing Change Room Intermediate Monitoring Room SW 2C Nuclear Research Lab Office and Lab Revision 0 16 of 69 SW 2D Walk-in Cooler and area surrounding cooler accessed from outside SW 2E Nuclear Research Lab Office and Lab SW 2F Isotope Storage General Storage Figure 2.2 AJB Reactor Facility Basement Areas Medical Center Basement N I,<f J ISW 2F fun Arrows indicate evacuation route Dashed line indicates operation boundary To first floor-research Double dashed line from the reactor to the console Indicates cable conduit Revision 0 17 of 69 The reactor room ventilation supply provides heated or cooled 100% outside air to the reactor laboratory at the rate of 1,520 CFM through six ceiling ducts. The exhaust effluent of 2,970 CFM exits the reactor room into the outside air by means of an exhaust fan installed in the outside wall of the building. In addition, two laboratory fume hoods (Figure 2.2) are operated continuously and exhaust a total of 919 CFM by means of fans installed on the roof of the medical center (Figure 2.3). Since the blower for the hood exhaust is on the roof, resulting in the entire duct having a negative pressure, any leakage would be into the duct, eliminating the potential for exposure within the medical center. The ventilation exhaust point of interest is the area labeled Reactor Lab Hoods (Figure 2.3).Figure 2.3 Veterans Affairs Medical Center Roof Exhaust Locations OPC Clinic rXenon Exhiaust Elev. 405'- O'L' XMain HosMit Reactor Lab Hoods uclear edicine Eev. 371'- OI Suite I Exhaust Elev. 37V-O Revision 0 18 of 69 Reactor Pit The reactor is located near the bottom of a cylindrical pit 6.1 meters below ground level. The pit contains a steel tank of 208 cm (inside diameter) with a wall thickness of 0.64 cm. The tank rests on a 28 cm concrete slab, and approximately 25 cm of poured concrete surround the outside of the tank. The inside of the steel tank is covered on the sides by a layer of gunite approximately 5 cm thick and on the bottom by poured concrete approximately 10 cm thick. The entire inner surface is coated with two applications of a waterproof epoxy resin. The reactor pit has been designed to ensure against leakage of the water. The gunite and its waterproof coating protect the steel tank against corrosion by water, and if a small defect in the coating should occur, the steel tank will provide a secondary containment vessel. 4.9 meters of water provides shielding above the reactor core.Figure 2.4 provides a schematic of the reactor and pit.Three emergency storage pits are located immediately adjacent to the reactor tank.These pits are vertical steel pipes 25 cm in diameter and 305 cm long. The pits were never used but could have been filled with water to store irradiated specimens or failed fuel elements.Revision 0 19 of 69 Figure 2.4 Reactor and Pit Revision 0 20 of 69 Reactor Core and Graphite Reflector The core is at the bottom of the reactor pit and is approximately 0.36 meters long.The core contained 85 fuel-element positions; 57 contained active fuel elements, and graphite elements (elements in which the uranium-zirconium-hydride fuel is replaced by graphite) occupied the remainder of the positions. The assemblies were supported above by the top grid plate and below by the bottom grid plate.Both grid plates were 1.9 cm of aluminum. The final core consisted of 56 aluminum clad fuel elements and one stainless steel clad element that was added to the core on October 2, 1995.The core was cooled by natural circulation of water flowing through the core from bottom to top.A cylindrical reflector 30.5 cm thick (inner diameter of 43 cm and outer diameter of 107 cm) surrounded the core. The graphite reflector is completely encased in a welded aluminum can. Reflectors on the top and bottom of the core are 10 cm graphite sections encased in fuel element cans. General Atomic reports that impurities in the graphite may include iron (Fe), silicon (Si), titanium (Ti), zirconium (Zr), and calcium (Ca).Irradiation Facilities Irradiation facilities are part of the reactor structure and provided for the production of radioisotopes. These include a rotary specimen rack located in the well in the reflector can, a pneumatic transfer tube, and a central thimble. In addition, odd-shaped specimens could be irradiated in the water outside the reflector. The rotary specimen rack (also referred to as the "Lazy Susan") is an aluminum ring that could be rotated around the core. Forty evenly spaced aluminum cups are hung from the ring and served as irradiation specimen holders. The ring could be manually rotated from the top of the reactor pit so that any cup could be aligned with the single isotope-removal tube that runs to the top of the reactor.Additional detail about the rotary specimen rack can be found in the Safety Analysis Report (SAR).The pneumatic transfer system (PTS) provided for the production of isotopes with short half-lives. It consists of two tubes leading down through the water tank to a position at the outer edge of the core where the tubes are joined. The specimen was fed in and out through one of the tubes and a blower connected to the other tube provided the pressure difference to inject or eject the specimen. Specimens were inserted and removed from the PTS in the reactor laboratory. Revision 0 21 of 69 The central thimble was installed to provide irradiations or experiments in the region of maximum neutron flux. The thimble consists of a vertical aluminum tube with a 3.4 cm inner diameter leading from the top of the reactor pit through the center of the core and ending at the bottom of the core. The vertical aluminum tube has holes in the region of the core to ensure water flow through the core during reactor operation. The shield water could be removed from the portion of the central thimble above the upper grid plate using air pressure to force the water out of the tube through the holes in the bottom. This provided a highly collimated beam of neutron and gamma radiation for experiments. The central thimble was only used once during operation to determine dose levels during such use.Control Rods and Control Rod Drives Three boron carbide control rods were operated in perforated aluminum guide tubes. The control rod has an extension tube that connects to the control rod drive mechanism. The control rod drive mechanism is located on the bridge at the top of the reactor pool. Control rods and control rod drives remain in place in the tank.Reactor Water Cooling and Purification The reactor was cooled by natural convection of the pool water. A 5-ton freon vapor compression chiller with an air cooled condenser was used as the heat sink.Water from the reactor went through a water monitor where the temperature, gamma activity, and conductivity of the water were measured. The water was pumped to the chiller unit, through a filter and a mixed-bed demineralizer, and then returned to the tank.The water system served four functions: I. Maintain low conductivity of the water to minimize corrosion of reactor components.

2. Reduce radioactivity in the water by removing particulate and soluble impurities.

3. Maintain optical clarity of the water.4. Provide a means of dissipating the heat generated in the reactor.Nuclear Control System A wide-range fission chamber and a boron-lined uncompensated ion chamber provided the reactor core monitoring system. The fission chamber and ion chamber were removed in December 2002.Revision 0 22 of 69 Facility Changes and Equipment Replacements and Approximate Dates The following list identifies the major facility changes that could have impacted the radiological status of the facility.

Additional information notes from the review of historical information is contained in APPENDIX A to this report.August 1966: The rotary specimen rack was replaced. The original rotary specimen rack is stored along with another irradiated component in a below ground location accessed from the outside noted on Figure 2.2 as SW 2D.Sometime in the 1960's, the PTS, which was originally routed to the ISt floor, was cut and routed to the reactor laboratory. 1993 or 1994: Re-routed Ar-41 exhaust from the PTS from outside the reactor pit and connected into a fume hood in the reactor laboratory. 1995: A stainless steel TRIGA fuel element was added to the core on October 2, 1995, due to the core fuel bum-up since 1959.1995: The terminus end of the PTS tube was replaced due to leakage. Leakage and leakage repairs are a frequent entry in the reactor records between 1983 and 1995.1999: The original 1959 General Atomics console was replaced with a solid state General Atomics Mark II console along with safety, shim, and regulating rod drives.1999: An inner wall between SW2A and SW2B was redesigned. 2.4 Identity of Contaminants Lead in paint and asbestos in building materials are the hazardous contaminants of concern that were analyzed for during the characterization survey.The radionuclides of concern within AJB reactor facility are those associated with the sources possessed, long lived nuclides from experiment irradiation, and fission and activation products. The list of radionuclides from 10 CFR 61 Tables 1 and 2 were analyzed for as well as a number of other radionuclides that are typically identified in reactor facilities. Short-lived radionuclides from reactor operation and experiments are not a concern for decommissioning and were not analyzed for. Nuclides in this short lived category include: Na-24 (15 hour half-life), Al-28 (2.3 minute half-life), V-52 (3.75 minute half-life) Co-58 (70 day half-life), Fe-59 (49 day half-life), Zr-95 (64 day half-life), Nb-95 (35 day half-life), Tc-99m (6 hours half-life), I-131 (8 day half-life), Cs-136 (13 day half-life), Ba-140/ La-140 (13 day half-life), and Sm-153 (47 hour half-life).

The resin sample was sent to Eberline Services Laboratory for analysis. Sample analysis can be used to determine the radionuclides of concern for decommissioning and final survey. The results of the resin analysis are summarized in Table 2.2. Many of the results are below the minimum detectable activity (MDA); those above the MDA are bolded. Attachment 1 to this report provides the Eberline Services Final Report of Analysis Summary and the case narrative. APPENDIX F provides Eberline's analysis report package for this sample.Derived concentration guideline levels (DCGLs) were calculated from the nuclide mixture identified in the resin sample. The NRC criterion (10 CFR 20.1402) for unrestricted use is 25 mrem/yr annual total effective dose equivalent. Therefore, the DCGL is the activity level that would deliver this dose to an average member of the public. The calculation and resulting DCGL of 27,000 dpml100 cm 2 are provided in Section 8 and Attachment 2 of this report. The data collected during this characterization were collected using a conservative value of 5,000 dpm/l 00 cm 2 as a preliminary guideline. The resin sample analysis results were available after demobilization from the site, and the data were then reviewed against the site specific DCGL. The 5,000 dpm/lOO cm 2 preliminary guideline was a conservative estimate for survey planning and data collection.

The use of detectors calibrated using Tc-99 and Th-230 for the characterization was conservative considering the energies and yields of the alpha and beta particles emitted from the range of potential radionuclides at the AJB Reactor Facility. Coincidentally, Th-230 was the only alpha emitting radionuclide detected in the offsite analysis.2.5 Historical Site Assessment An historical site assessment was performed and information gathered was used to design the Characterization Survey Plan and survey packages. APPENDIX A contains a list of the documents reviewed. The following past and present individuals provided time for interviews and the information provided was extremely useful for completing the characterization effort.Individual John Claassen Mike Christiansen Ed Fennell Lynell Klassen, M.D.Dean Tuma, Ph.D.Greg Hansen Ron Jones Jan Vallery Position Reactor Manager Radiation Safety Officer Research Service Electronics Technician Associate Chief of Staff for Research Research Chemist Reactor Operator Engineering Health and Safety Manager Employment Dates 2/89 -1/03 1996 -present 1976 -present 1991 -present 1963 -present 1984- 1988 1996 -present 1989 -present Revision 0 27of 69 3.0 ORGANIZATION AND RESPONSIBILITIES The on-site survey team consisted of a project manager, senior health physics (HP)technicians, and a data management technician.

12. Developing a report that addresses the survey objectives and survey results.Revision 0 29 of 69 5.0 SURVEY OVERVIEW The characterization followed the general guidance provided in NUREG-1575, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM).

The characterization survey is frequently the most comprehensive of the surveys in the decommissioning process, and as such, more measurements are frequently taken in this survey than in the Final Status Survey. The intent was to collect enough measurements so that the areas could be appropriately classified for remediation and final survey.The survey included survey unit classification, systematic and/or random measurements, and surface scans. The characterization survey was based in part on the guidance contained in the MARSSIM. Design of the survey included the establishment of the Data Quality Objectives, defining the number and types of measurements per survey unit, and specifying the MDA requirements. To ensure that the measurements were of facility residual contamination rather than influenced by sources or radioactive waste, it was optimum to have materials such as waste, sources, and irradiated samples, removed prior to characterization. Areas where measurements were influenced by a nearby source required taking a shielded background measurement at each survey measurement location. This technique provided the best estimate for subtracting the influence from sources or waste materials. 5.1 Data Quality Objectives To ensure that the survey would provide the necessary data for the VA to develop a detailed decommissioning plan and provide data that might be used as final survey data, the following survey objectives were established in the Characterization Survey Plan and the Quality Assurance Project Plan.1. Identify the radionuclides of concern and DCGLs by a. collecting representative samples throughout the facility, b. analyzing samples at an onsite and offsite laboratory, and c. reviewing previous data.2. Identify the extent of the contamination and, where applicable, the depth of the contamination.

3. Estimate waste volumes.4. Estimate the scope of future remediation and decontamination required to achieve license termination.

5. Assure instrument accuracy through calibration of instrumentation with sources traceable to the National Institute of Standards and Technology (NIST) and the thorough daily verification of instrument response QC Revision 0 30 of 69 checks.6. Assure instrument reliability of both field and laboratory instruments by performing daily QC checks as required by Duratek procedure REDS-INST-104 Calibration and Test Requirements for Radiation Protection Instrumentation.

7. Ensure representativeness of survey measurements and samples by a careful overview of all data with particular focus on duplicate and split sample analysis and results.8. Ensure completeness of survey packages through repetitive, concurrent reviews of survey results relative to the Characterization Survey Plan and survey package data requirements.

9. Provide the radionuclide data for the determination of DCGLs.10. Comply with the Site Characterization Survey Plan by ensuring all the surveys are complete and meet sensitivity, accuracy, and reproducibility requirements, and are well documented.

11. Ensure data collection is optimized by walking down all areas to be surveyed as part of the characterization survey package development.

Minimum data requirements will be defined, special conditions identified, specific instruction given, etc. during the walkdowns.

12. To minimize uncertainty, efficiency checks, source checks, background checks, data reviews, etc. will be conducted.

13. MDAs for each measurement will be set at the following levels:* 1000 dpm/lOOcm 2 direct beta* 100 dpm/lOOcm 2 direct alpha* 200 dpm/lOOcm 2 removable beta* 20 dpm/lOOcm 2 removable alpha 14. To ensure that samples selected for offsite analysis receive the proper controls necessary to reduce the possibility for lost or mislabeled samples, the contract laboratory chain of custody forms will be implemented to address the steps and requirements for the identification and control of samples.Surveys and data evaluation were based on the guidance in NUREG-1575, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM), and included measurements for exposure rate, direct surface activity, removable activity, and radionuclide analysis.Revision 0 31 of 69 5.2 Structure Surveys Characterization surveys of building surfaces and structures (including paved areas outside the facility) included surface scanning, surface activity measurements (alpha and beta), exposure rate measurements, and sample collection (e.g., smears, subfloor soil, water, paint). Both systematic and biased measurements were taken. Biased measurements were based on the judgment of the survey team and included areas where scans were elevated.

Biased measurements provide information on the upper range of residual contamination levels.5.3 Land Area Surveys Characterization surveys for surface and subsurface soils included surface gamma scans, and soil sample collection and analysis.Boring samples were obtained at 4 locations to depths of 10 feet below the reactor pit (approximately 36 feet) to determine the vertical and horizontal contamination (if any) from the reactor either due to neutron activation or tank leakage. It is noted that the reactor personnel indicate that operational data, such as make up water volumes, indicate that there was no tank leakage. Three test wells were installed outside of the facility and the removed soils sampled. The test wells were installed to depths of 100 to 131 feet.5.4 Background Study A background study was performed on building materials to determine direct measurement levels from areas similar to but not associated with reactor operations. The local background determination served as the baseline for the characterization survey data. The background study could be used in the evaluation of the onsite survey data and, as such, was designed so that measurements (and if necessary, sampling, sample preparation, and sample analysis activities) were similar to those used for the onsite measurements. The background reference areas were selected from areas not impacted by operation of the reactor or the hospital or research facility's radionuclide use. The reference areas had similar physical, radiological, and geological characteristics as the impacted survey unit areas but were unaffected by radionuclide use.The data collected during the background study was reviewed for trends and statistics performed on the various data sets. The background data could be used for evaluation of the site radiological survey data. Data collected from the AJB reactor facility site could be compared to the background data to determine if it is statistically different. If site residual activity levels are near the expected DCGL 2 , 2 DCGLs were developed after the characterization survey was performed, and results of the radionuclides and their relative activities were identified through analysis at Eberline Services laboratory. Revision 0 32of69 then a background statistic could be developed which could be added to the residual radioactivity criteria to establish the cleanup goals.Direct beta measurements were taken for the various background surfaces. The number of measurements for each surface were defined in the survey package.A background study of soils was not performed because no licensed activity was detected in the characterization soil samples. If radionuclides attributable to licensed activities (e.g. Cs-137) had been identified in significant quantities in the characterization soil samples, then a background study would have been performed on soils, sediments, and waters with common characteristics to the samples and measurements collected onsite but that were unaffected by reactor operations. 5.5 Characterization Survey Classification Approach After completion of the background study, characterization surveys were performed. The characterization surveys used a classification approach that distinguishes between the following:

• Impacted -Areas potentially affected by reactor operations (e.g., areas that may have been contaminated and/or activated by reactor operations)
• Non-Impacted

-Areas not suspected of being affected by reactor operations The site area classifications were based on a review of the site history as documented in the updated Safety Analysis Report (SAR), the AJB reactor facility emergency plan, and information gathered during the historical site assessment. 5.6 Impacted Area Survey and Sample Plan Methodology Areas classified as impacted had the potential of being radioactively contaminated based upon operations conducted in the area. These areas comprised the following.

• Reactor Room and Pool (SW 2)* Nuclear Research Labs (SW 2C)* Radioisotope Reactor Research Laboratory (SW 2)* Office and Lab (SW 2E)* General Storage Area (SW 2F)* General Storage Area -vertical and horizontal storage tubes* Refrigeration Area (SW 2D)* Supply Warehouse (SW 3)* Male Locker Room, Shower, and Restroom (SW I and SW IA)* Pit Outside the Walk-in Cooler (accessed from outside, houses the walk-in cooler)Revision 0 33 of 69
• East Cooling Pit Area (main reactor ventilation unit, area also houses water filters, water demineralizer, and a sump, accessed from outside)* Dark Room (SW 2B)* Electron Microscope Room (SW2A)* Fume Hood Ventilation Units in Labs and at the Roof Discharge points* Penetrations and Drain Lines in the various rooms* Stairway (south side of the Reactor Research Laboratory)

The objective of measurements and sampling in impacted areas was to confirm the presence or absence of radioactive material in excess of background readings and to determine the extent of contamination in building, equipment, and environmental media through a program of systematic and biased measurements and sampling.A 1 square meter grid reference was established and measurements taken at each grid intersection on floors and walls up to 2 meters.Ceilings were surveyed as impacted -Class 3 in accordance with the instructions in the survey package.Surface measurements included:* direct beta measurements,* direct alpha measurements,* beta scans inside, exposure rate scans outside, and* removable alpha and beta (smears).Biased measurements were taken at locations showing elevated scans or locations where contamination is likely (such as horizontal surfaces). 5.7 Non-Impacted Area Survey and Sample Plan Methodology In non-impacted areas the presence of radioactive material is not expected. These areas included the areas chosen for background surveys and outside areas (the roof, building exteriors, sidewalks, parking lots, and soils). Non-impacted areas were divided into sampling strata representing distinct statistical populations based on type of environmental medium, depositional mechanisms, or structural and process similarities. The samples and measurements for non-impacted included: direct beta, direct alpha, beta scans for inside areas, gamma scans for outside areas, surface and subsurface soil samples, and removable alpha and beta (smears).Revision 0 34 of 69 5.8 Neutron Activation Analysis of the Core Area Neutron activation analysis calculations were performed to determine potential radionuclides in the materials surrounding the reactor. The reactor pit materials are described in Section 2.3 of this report. This analysis estimated the extent that concrete, soil, and other media materials may have become radioactively activated as a result of reactor operations. 5.9 Deep Soil Borings HDR Engineering performed a total of four borings around the core area. Three of these borings were performed vertically. One angular boring allowed for a sample beneath the core area. The test borings were drilled in the soil backfill zone around the reactor pit. These borings varied in distance from the reactor wall to develop a profile of activity that may exist out from the reactor and into the soil.The borings extended to a depth of 10 feet below the base of the reactor pit. Soil samples were initially analyzed using the onsite gamma spectroscopy equipment. If significant activity had been found in any sample, then the highest representative sample would have been shipped off site for additional analysis (e.g., hard-to-detect nuclides). 5.10 Hazardous Materials Assessment A hazardous material walk down was performed to identify possible hazardous constituents (e.g., asbestos, lead, PCB oils, PCB lead based paint, PCB lamp ballasts, mercury lamps, etc.) that may be present at the facility.No contaminants other than lead and asbestos were discovered. Asbestos The Assessment Group Inc. conducted a modified AHERA asbestos inspection and obtained applicable samples for analysis at the AJB reactor facility. Bulk asbestos samples were sent to an accredited laboratory for analysis.Lead Sampling for lead paint was initially conducted using chemical reaction swabs. At the conclusion of the swab sampling, lead paint chip samples were taken and sent to a laboratory for analysis.Revision 0 35 of 69 5.11 Surface and Subsurface Soil Samples Surface (O -6") and subsurface (O -12") soil samples were taken in accordance with survey package instructions. Because no outside areas showed elevated gamma scan measurements, samples were taken in biased judgment locations where there is a potential for material contaminated by reactor operations. The samples were analyzed on site by gamma spectroscopy. 5.12 Number of Samples/Measurements The simplified procedures in MARSSIM recommend a minimum of 30 measurements in each survey unit. A minimum of 30 measurements in each survey unit was used for this characterization. In accordance with guidance in MARSSIM, inside grids were I square meter for the impacted survey unit floors and walls below 2 meters. Grids for non-impacted outside areas are not required.Revision 0 36 of 69 6.0 SURVEY DESIGN AND IMPLEMENTATION The purpose of the survey was to collect sufficient survey data to characterize AJB Reactor Facility. The project technician(s) performed surveys according to survey packages, specific procedures, and the Characterization Survey Plan. Implementation of this Characterization Survey Plan included the following:

• Survey instrumentation was set up and source checked to ensure proper operation.
• The project manager and technicians performed preliminary inspections of the areas to identify additional specific survey requirements.
• The technicians or project manager developed survey packages for the survey areas.* The technician gridded the survey areas as specified by the survey package protocols and/or marked the survey locations as applicable.
• The technician took survey measurements and analyzed samples using appropriate calibrated instruments and performed daily source and background checks before and after each day's work.* Direct survey data were collected during the project and downloaded from the survey instrument into a database for storage and processing.
• Measurement locations were marked on a map.* The project manager reviewed the completed survey packages to ensure that all required surveys had been performed.
• The technician and project manager reviewed the survey results to identify any areas exceeding the preliminary guideline value of 5,000 dpm/l 00 cm 2.6.1 Instrumentation and Selection Selection and use of survey instrumentation ensured sensitivities were sufficient to detect the identified radionuclides at the minimum detection requirements.

Table 6.1 provides a list of the instruments, types of radiations detected, and calibration sources that were used. Table 6.2 is the table from the QAPP that defined the project detection sensitivity requirements. Duratek used the Ludlum Model 2350 Data Logger with a variety of detectors for direct beta measurements and beta scans. The Data Logger is a portable microprocessor computer-based counting instrument capable of operation with NaI(TI) gamma scintillation, gas-flow proportional, GM and ZnS scintillation detectors. Detector selection depended on the type of survey, surface contour, and survey area size. The project team typically used the 126 cm 2 gas-flow proportional detector for direct alpha and direct beta measurements for most areas, and the 15.5 cm 2 GM detector for smaller areas in which the gas-flow proportional detector will not fit or for the release of items and equipment. Analysis for removable alpha and beta activity was performed using a Tennelec LB 5100 low background smear counter at the Duratek facility in Kingston, Tennessee.

Calibration includes:* High voltage calibration,* Discriminator/threshold calibration,* Window calibration,* Alarm operation verification, and* Scaler calibration verification The detector calibration included:* Operating voltage determination,* Calibration constant determination, and* Dead time correction determination Calibration labels showing the instrument identification number, calibration date, and calibration due date were attached to all portable field instruments. Revision 0 39 of 69 6.1.2 Sources All sources used for calibration or efficiency determinations for the survey were representative of the instrument's response to the identified radionuclides and are traceable to NIST.Health physics technicians controlled the radioactive sources used for instrument response checks and efficiency determinations. Sources were stored securely when not in use.6.2 Survey Unit Classification Survey units are discrete areas consisting of building surfaces of a specific size and shape. Survey units were defined based on the site's history, potential for residual contamination, and physical characteristics. All impacted areas were divided into survey units. Impacted areas were those areas with a potential of being contaminated. Non-impacted areas were generally areas that did not have a potential for being contaminated. Background measurements and outside areas were surveyed as non-impacted. hipacted survey units were classified as Class 1, 2, or 3. A Class 1 survey unit is a survey unit where contamination levels prior to remediation were anticipated to approach or exceed the preliminary guideline level (5000 dpm/l 00 cm 2 beta). A Class 2 survey unit is a survey unit that did not have contamination approaching or exceeding the preliminary guideline level. Typically Class 2 survey units would not require remediation. A Class 3 survey unit is expected to contain contamination at a fraction (< 10 %) of the preliminary guideline. Although no areas at the AJB Reactor Facility were expected to contain residual activity, floor areas where radioactive materials were used or stored were conservatively classified as Class 1.Survey units are limited in size to ensure adequate survey coverage. The type of measurements and scanning coverage are also defined for each survey unit classification. The size limits, measurements, scanning frequency, and a conservative preliminary classification are specified in Table 6.3.Revision 0 40 of 69 Table 6.3 Survey Units Impacted Survey Size Limit, m 2 Scan Frequency AJB Reactor Unit Classification Facility Initial Classification Class I Building < 100 100 % coverage of Floors of reactor Surfaces! accessible floors facility rooms, structures walls to 2 meters, and wall vaults Class 2 Building <1,000 10- 100% No areas at the AJB Surfaces/ coverage reactor facility were structures classified as Class 2 Class 3 Building No limit Judgment Walls, ceilings, Surfaces/ overhead structures structures Based on the probability for contamination, the floors were classified as Class 1, and the walls, ceilings, and overhead structures were initially classified as Class 3 impacted.The survey plan included guidelines to reclassify survey units when residual activity was encountered at higher than a preset limit during the survey process.No areas required reclassification. 6.3 Survey Package Development For each survey area/unit, the project team developed a package by performing a walk-down and preparing a worksheet/tracking sheet outlining the general survey instructions, location codes, and any specific survey instructions for any abnormal conditions within the survey area. Completion and review signature blocks were used to track the progress of the surveys.During the survey, the technician updated the survey package(s) with the survey data and results of any special surveys or sample analyses performed. Revision 0 41 of 69 6.4 Survey Protocols/Requirements The characterization of the building consisted of gamma scans, beta scans, fixed beta measurements, fixed alpha measurement, and smears for gross alpha and beta analysis. Gamma scans were performed over outside areas. Surveys were performed as follows: 6.4.1 Surface Gamma Scans and Beta Scans For class 1 survey units, gamma scans and beta scans were performed over 100% of the accessible building surfaces (interior) using a Nal detector and a gas-flow proportional detector while listening to the audible output of the instrument. There were no class 2 areas. For Class 3 survey units, beta scans were performed over approximately 10% of the accessible building surfaces. All areas of elevated activity were identified for further investigation and potential decontamination. Beta scan speeds were established such that contamination at levels below the preliminary guideline of 5000 dpm/100 cm 2 beta would be detected (using the MDA scanning equation defined in section 7.0).Gamma scans were performed with 2 inch by 2 inch Nal(TI) detectors approximately 10 cm from the surface at a scan rate of approximately 0.5 m/s. The MARSSIM approximates the soil detection sensitivity under these measurement conditions to be 6.4 pCi/g for Cs-137 and 3.4 pCi/g for Co-60. These radionuclides were identified in the resin sample analysis.The sensitivity provides information on the activity concentrations that can be seen with gamma scans.6.4.2 Direct Alpha and Beta Measurements Direct alpha and beta measurements were taken on the structural surfaces of AJB Reactor Facility within each survey area/unit. A minimum of 30 beta measurement locations were established in each survey unit. Alpha measurements were taken at approximately 10% of the measurement locations. 6.4.3 Removable Activity Measurements Smears were taken at each direct measurement location for gross alpha and beta analysis.Tritium smears were taken at approximately 10% of measurement locations. Revision 0 42 of 69 6.4.4 Grid Spacing Only floors and walls in Class I areas were gridded. All measurement locations were marked on appropriate drawings. The grid spacing was 1 square meter unless otherwise directed by the project manager.6.5 Survey Records The project team maintained records of surveys in the survey packages for each area. The survey package included the following records depending upon the survey design and protocols:

• Survey Package Worksheet giving the package identification, survey location information, general survey instructions, and any specific survey instructions
• Survey Unit Diagram of the area to be surveyed as available* Photographs of the survey area, as necessary, to show special or unique conditions
• Printout of laboratory analysis results (if performed)
• Ludlum Model 2350 data files and associated spreadsheets for all radiation survey measurements Duratek used a proprietary computer program to download the contents and survey data from the Data Logger's memory to a database and generate a survey report that presents all raw data, converted data, and information by survey location.

The survey technician and supervisor reviewed these reports for completeness, accuracy, suspect entries, and compare the data to requirements of this plan and the Quality Assurance Project Plan (QAPP) for this characterization. Any changes to the database tables, such as detector efficiency and background that could affect survey results required management approval.Data and document control included the maintenance of the raw data files, translated data files (spreadsheets), and documentation of all corrections made to the data. The databases were backed up on a daily basis.Revision 0 43 of 69 7.0 MINIMUM DETECTABLE ACTIVITY, MDA MDA is defined as the smallest amount or concentration of radioactive material that will yield a net positive count with a 5% probability of falsely interpreting background responses as true activity. The MDA is dependent upon count times, geometry, sample size, detector efficiency background, and for scanning the scanning rate and the efficiency of the surveyor.The MDAs for direct alpha and beta measurements and analyses for removable activity were set at the values specified in the QAPP (Table 6.2 of this report). The MDA for beta scans was set equal to or less then 5000 dpm/100 cm 2.Since the MDA for scanning was equal to or less than the preliminary guideline, the scanning MDAs did not affect the number of measurements or samples required to evaluate a specific survey unit.Direct Measurements The equation used for calculating the MDA for direct measurements is:-+ 3.29 &L+ -MDA t ts tb E ( `)Where: MDA = Minimum Detectable Activity (dpm/100 cm 2)Rb = Background Count Rate (cpm)tb = Background Count Time (min)ts = Sample Count Time (min)A = Detector Area (cm 2)E = Detector Efficiency (c/d)Beta Scans The equation used for calculating the MDA for beta scans is: d' ;* 60 MDA=V*+/-A Ei*E,*f;* o100 Where: MDA = Minimum Detectable Activity (dpm/100 cm 2)d' = Decision error taken from Table 6-5 of MARSSIM i = Observation counting interval (scan speed divided by the detector width)bi = Background count per observation interval Es = Detector Efficiency counts per disintegration (cfd)Revision 0 44 of 69 Es = Surface Efficiency (typically around 50% for beta contamination on concrete)p = Surveyor Efficiency (typically 0.5 -0.75 MASSIM recommends using 0.5)A = Detector Area (cm 2)8.0 CHARACTERIZATION SURVEY RESULTS All survey package results with the associated documentation and drawings of each are contained in APPENDIX B to this report. A summary of the alpha and beta smear sample analysis is contained in Attachment 4 of this report. Summaries of tritium smears, total beta surface contamination measurement, total alpha surface contamination measurements, gamma exposure rate measurements, and gamma spectral analysis results can be found in Attachments 5 through 9 of this report. Figure 8.1 provides a reference of the breakdown of areas into the survey package numbers. A key to the location codes can be found in the front of APPENDIX B.A slight negative bias was noted on the smear sample results. The smear results are reported in net dpm/100 cm 2.A blank smear sample is counted for 20 minutes daily prior to counting samples. The blank smear result is then subtracted from each subsequent measurement for the day. Most of the smears taken at the A.J. Blotcky facility did not show contamination and were essentially background measurements. The daily blank may have had slightly more background activity on it than the samples obtained during characterization. All data was reviewed and because the blank background data are low, the measurement counts are low, and the MDAs are all low, this bias does not change the decisions about the data. A reanalysis of the data without background (blank sample)subtraction would make all results greater than zero but would still be minimal.A slight negative bias was also noted for a few locations of direct measurements. Review of the data showed these locations had measurements that were very close to and sometimes slightly less than the instrument background measurements. The data are well below the MDA and if the background measurements were removed from the data sets showing a negative bias, the conclusion for these locations would still be that the areas do not contain residual activity.Revision 0 45 of 69 Figure 8.1 Survey Areas I h R OU P6::mga A0003 Pit-acage A0002 IlSacREWge AO1OOI Arrows indcate evacuaton route N Dashed IMe ikcates operaon bouncy To first floorresearch Revision 0 46 of 69 8.1 Enviromnental Background Results (Package NOOO1)Package Description Background measurements were taken on surfaces with similar material characteristics as those being measured for the characterization.

Other than iodine-125, radioactive materials were seldom used in this area. Research personnel used the area for non-radioactive studies. The room was completely refurbished to house a FACS SCANNER (high speed cell sorter)used in cancer research during 1999. In the spring of 2002 the FACS-SCANNER was moved to a new location in anticipation of decommissioning. Package Description Measurements of the floors, walls, and structures within the room were surveyed.Sinks were surveyed as part of the structure (the counter top). Drains were surveyed as part of the systems package (D0001).Data Summary Summaries of the data collected are presented in Table 8.3. The data are all low in activity (many below the MDA), and no measurements exceeding approximately 25% of the preliminary guideline levels were noted.Table 8.3 Rooms SW2A and SW2B Results (Package A0001)Location Description Measurement Number Maximum Mean Std Dev Type __ _ dpm/100 cm2? dpm/100 cm, dpm/100 cm 2 AOOOlOlFOI Tile Floor Total beta 35 640 241 192._ contamination AOOO1OSOI Structure I Cabinets Total beta 5 640 202 262 contamination AOOOlOIS02 Structure 2 Cabinet/Sink Total beta 10 97 -61 132 contamination AOOOIOISO3 Structure 3 Cabinet/sink Total beta 5 -132 -191 71 contamination AOO01OIWOI-Walls 1-4 Total beta 58 682 64 221 W04 contamination AOOOIOIFOI Tile Floor Total alpha 33 51 7 16 contamination AOOOlOIWO1-Walls 1-4 Total alpha 58 38 4 13 W04 contamination AOOO I01 FOI Tile Floor Removable 34 3 0 2 alpha AOOO 10I FOI Tile Floor Removable 34 4 -4 4 beta AOOOIO1SO Structure I Cabinets Removable 5 3 0 2 (smears) alpha AOOO1OISOI Structure I Cabinets Removable 5 13 6 5 (smears) beta AOOOIO IS02 Structure 2 Cabinet/Sink Removable 10 3 0 2 (smears) alpha AOOOIOIS02 Structure 2 Cabinet/Sink Removable 10 4 -2 4 (smears) beta Revision 0 49 of 69 Location Description Measurement Number Maximum Mean Std Dev Type .dpmIlOO cm 2 dpm/100 cm 2 dpnJ100 cm, AOOOIOIS03 Structure 3 Cabinet/sink Removable 5 3 1 2 alpha AOOOIOIS03 Structure 3 Cabinet/sink Removable 5 0 4 4 beta AOOOlOlWOI-Walls 14 Removable 58 7 0 2 W04 alpha AOOOlOIWOI-Walls 14 Removable 58 9 -3 5 W04 beta AOOOIOIFOI Rn.

This area was primarily used for reactor operations and maintenance. The area served as the reactor manager's office, research office, and records retention area. The pneumatic tube system is located in this area.The majority of irradiations performed in this area consisted of various isotopes with half-lives of less than 10 minutes. Samples that were irradiated were prepared in adjoining rooms and counted in the shield located in the Southeast corner of the room.Package Description Measurements of the floors, walls, primary cooling system pit, accessible parts of the pneumatic transfer system lab counter tops, trenches, and the structures within the room were surveyed. Sinks were surveyed as part of the structure (the counter top). Trench TOI is the sub floor around the top of the reactor. Trench T02 is the conduit below the floor for cables and PTS tubes. Drains were surveyed as part of the systems package (DOO01). The components within the reactor pool were characterized with an R07 and a high range detector; measurements obtained at a plane with the top of the reactor.Data Summary Summaries of the data collected are presented in Table 8.4. Data are generally low in activity. The reactor pool cover, the pneumatic transfer system, and the east cooling pit floor are noted to have measurements exceeding 1,000 dpm/100 cm 2 .The components within the reactor pool ranged from 0.1 R/hr to 1.5 R/hr (see reactor core profile figure in package A0002 contained in APPENDIX B to this report). The east cooling pit was surveyed as a structure. The reactor cooling system piping and demineralizer tank were assumed to be contaminated due to the Revision 0 50 of 69 activity of the resin sample obtained from the system. No additional measurements were taken to characterize the tank. The tank and all piping and instrumentation are assumed to be contaminated and will need to be disposed of as radioactive waste.Table 8.4 Room SW2: Reactor Room Console Area, Reactor Pool, Primary Cooling System Pit, Structures and Trenches Results (Package A0002)Location Description Measurement Number Maximum Mean Std Dev Type dpml100 cm2 dpm/lO0 cm 2 dpm/1OO cm 2 A000201FO1 Rx Room Console Area/ Total beta 92 12116 313 1399 Tile Floor contamination A000201S01 Structures 1/Lead Shield Total beta 5 125 -16 89 contamination A000201S02 Structure 2/ Rx Control Total beta 5 39 -107 116 Panel contamination A000201S03 Structures 3 /Lab Counter Total beta 10 361 138 133 contamination A000201S04 Structure 4 / East Cooling Total beta 31 1734 508 343 Pit contamination A00020IT01 Trench 1/Pit Surrounding Total beta 10 604 282 198 RX contamination A000201T02 Trench 2/ Pneumatic Total beta 10 1243 304 389 Transfer System contamination A000201WO1-Walls 1-4 Total beta 90 808 269 278 W04 contamination A000201FOl Rx Room Console Area/ Total alpha 91 50 4 15 Tile Floor contamination A000201WOl-Walls 1-4 Total alpha 91 50 4 15 W04 contamination A000201FOI Rx Room Console Area/ Removable 91 3 1 2 Tile Floor alpha A000201FO1 Rx Room Console Area/ Removable 91 0 -4 4 Tile Floor beta A000201S01 Structures I/Lead Shield Removable 5 1 0 alpha A000201SOI Structures 1/Lead Shield Removable 5 0 4 3 beta A000201S02 Structure 2/ Rx Control Removable 5 3 0 2 Panel alpha A000201S02 Structure 2/ Rx Control Removable 5 0 -2 2 Panel beta A000201S03 Structures 3 /Lab Counter Removable 10 3 0 2 alpha .A000201S03 Structures 3 /Lab Counter Removable 10 13 -1 6 A000201S04 Structure 4 / East Cooling Removable 31 7 .2 Pit alpha .A000201S04 Structure 4 / East Cooling Removable 31 6 -2 4 Pit beta A000201T01 Trench 1/Pit Surrounding Removable 10 7 1 3 RX alpha A00020IT01 Trench 1/Pit Surrounding Removable 10 69 7 23 RX beta Revision 0 51 of 69 Location Description Measurement Number Maximum Mean Std Dev Type dpml100 cm 2 dpnlOO cm A000201T02 Trench 2/ Pneumatic Removable 10 1 0 Transfer System alpha A000201T02 Trench 2/ Pneumatic Removable 10 8 -2 5 Transfer System beta A000201WOl-Walls 1-4 Removable 89 7 0 2 W04 alpha A000201WO1-Walls 1-4 Removable 89 17 -2 5 W04 beta A000201FO1 Rm.

This room was used primarily for storage. The room originally contained a 1.2 Curie sealed Cs-137 Shepard calibration source. The Shepard calibrator was moved in 1997 to the research wing of the hospital. The room was then used to store samples requiring refrigeration. Room 2C is the nuclear research office and lab area. This room/area was used for gas chromatography and sample preparation. Two hoods are located in this area.The hood located on the north side filters and discharges back into the room. The hood located on the south side discharges on the roof of the hospital. In 1993 the pneumatic transfer system exhaust was routed into the south hood. The sink in the hood of this area was used for disposal of liquid effluents to the sanitary sewer system.Package Description Measurements of the floors, walls, one drain, the walk in cooler, lab hoods, cabinets, and structures within the room were surveyed. Sinks were surveyed as part of the structure (the counter top). One drain was surveyed as part of this package. The lab hoods were surveyed up to the point of filtration. The ventilation system beyond this point was surveyed in package DOOOI.Data Summary Summaries of the data collected are presented in Table 8.5. The south hood (structure 02S01) has activity, which exceeds the calculated DCGL. This hood discharges to the ventilation system marked EF 11; the ventilation system was surveyed as V02 in the ventilation and drain system package (DO001). All other Revision 0 52 of 69 data are generally low in activity.Table 8.5 Rooms SW2C and SW2D (Packa e A0003)Location Description Measurement Number Maximum Mean Std Dev Type dpm/100 cm dpm/100 cm 2 dpmthO0 cmz A000301DOl Drain in O/S Walk-In Total beta 1 268 268 Cooler Pit contamination A000301FOI Walk In Cooler Floor Total beta 8 98 -55 169 contamination A000301SOI West Pit Surrounding Total beta 30 779 380 269 Walk-In Cooler contamination A000301WOI-Walk In Cooler Wall 14 Total beta 24 406 80 165 W04 contamination A000302F01 Rm.2C Tile Floor Total beta 28 737 172 191 contamination A000302S01 Rnm.2C/ Lab Hood Total beta 5 72211 14481 32272 contamination A000302S02 Rm. 2D Lab Hood Total beta 5 602 164 311 contamination _ _A000302S03 Rm.2C / Lab Cabinets Total beta 5 124 -60 145 contamination A000302S04 Rm. 2D / Lab Cabinets Total beta 10 408 -9 208 contamination_ A000302S05 Rm.2D / Lab Cabinets Total beta 5 211 23 160 contamination A000302W01-Rooms 2C&D / Walls 14 Total beta 34 2227 241 484 W04 contamination A000301FOI Walk In Cooler Floor Total alpha 8 8 -7 9 contamination A000301WOI-Walk In Cooler Wall 14 Total alpha 24 21 -6 12 W04 contamination A000302F01 Rnt2C Tile Floor Total alpha 27 46 5 19 contamination A000302S01 Pit Surrounding Walk-In Total alpha 3 34 13 19 Cooler contamination A000302S02 Rim 2D Lab Hood Total alpha 3 8 0 7 contamination A000302S03 Rm.2C / Lab Cabinets Total alpha 3 21 4 15 contamination A000302S04 Rim 2D / Lab Cabinets Total alpha 5 8 -4 13 contamination A000302S05 Rm.2D / Lab Cabinets Total alpha 3 34 4 26 contamination A000302W01-Rooms 2C&D / Walls 1-4 Total alpha 33 8 -S 11 W04 contamination A000301FOl Walk In Cooler Floor Removable 8 1 0 alpha A000301FOl Walk In Cooler Floor Removable 8 4 -5 5 beta A000301WOI Walk In Cooler Wall 1-4 Removable 24 3 -1 1 W04 alpha A000301WOI-Walk In Cooler Wall 1-4 Removable 24 8 -3 5 W04 beta Revision 0 53 of 69 Location Description Measurement Number Maximum Mean Std Dev Type _dpm/100 cmz dpm/100 cm dpm/100 cm A000302FOI Rmn2C Tile Floor Removable 24 7 0 2 alpha A000302FOI Rm.2C Tile Floor Removable 24 8 -3 5 beta _A000302SOI Rm. 2C/ Lab Hood Removable 5 1 0 alpha A000302SO1 Rm. 2C/ Lab Hood Removable 5 1081 217 483 beta A000302S02 Rim 2D Lab Hood Removable 5 3 0 2 alpha A000302S02 Rm 2D Lab Hood Removable 5 16 5 8 beta A000302W01-Rooms 2C&D / Walls 1-4 Removable 33 3 -1 1 W04 alpha A000302W01-Rooms 2C&D / Walls 1-4 Removable 33 8 -4 4 W04 beta I A000301FO1 Tritium 1 All tritium smears were less than the A000301WOl-smears instrument MDA (51 -61 dpm/100 cm 2)W04 4 A000302F02 3 A000302SOI-S03 5 A000302W01-W04 _ 4 8.6 Rooms SW2E and SW2F (Package A0004)Historical Sumrnai Room SW2E was a laboratory in support of research. This area housed two vacuum systems in support of hot atom chemistry. In the northwest is a committed fume hood (labeled EFIO) that exhausts to the roof on the 12*' floor.From 1992 to 1996 this hood was used for radiochemical neutron activation analysis. The sink on the southeast side was intermittently used to dispose of radioactive liquids to the sanitary sewer system. Glassware was cleaned in this area.Room SW2F is a vault room used primarily for storage. This room was also used for decay and storage of radioactive waste from the medical research facility. This room housed the molybdenum generators for the hospital until 1993.Package Description Measurements of the floors, walls, source room wall penetrations, floor storage penetrations, and the structures within the room were surveyed. Sinks were surveyed as part of the structure (the counter top). The fume hood to the point of filtration was surveyed as structure 02S01. The ventilation system beyond this point was surveyed in package DOOO. Drains were surveyed as part of the systems package (DOOOl).Revision 0 54 of 69 Data Summary Summaries of the data collected are presented in Table 8.6. The data show elevated direct beta measurements on the source storage area floor. Data reported are data collected after removal of radioactive materials from the area.Background measurements with the probe shielded with a plexiglass shield were taken at each survey measurement point. Each of these background measurements was subtracted from the corresponding survey point measurement. One tritium smear had measurable activity, but it is noted to be insignificant when compared to the tritium screening DCGL in the Federal Register of 1.2 E8 dpmn/100 cm 2.Floor and wall penetrations used to store radioactive materials survey results are included in this package. The well covers could not be removed on two of the floor wells; the other 8 floor penetrations were surveyed but due to the measurement geometry, the measurements are recorded in the survey package as "for information only."

The lab hoods numbered EFIO (in room SW2E surveyed in package A0004) and EFi 1 (the southern hood shown in Figure 2.2 surveyed in package A0003) were used for radioactive material experiments. These two hoods are dedicated hoods for radioactive materials and exhaust to the 12th floor roof. The ventilation systems after the hood filtration were surveyed in this package as 01 VOI (EFI0) and 01V02 (EFI 1). The vents can be accessed easily in four locations: (1) the entry point, (2) the 1st floor damper area, (3) the 4h floor, and (4) the doghouse on the roof.Package Description Measurements of the ventilation systems were obtained at each accessible location, after the fume hood filtration point.Measurements of the drains were made by removing the drain trap and surveying up to the nearest obstruction using a pipe detector. Surveys of drains marked OlD01, OD02, OID03, OID04, OID05, OID06, 01D07, and OlD1O were obtained. Drains marked OID08 and OD09 were not surveyed. Drain OID08 immediately angled so that the pipe detector would not fit beyond one inch. Drain 01D09 was behind the hood and could not be accessed.Data Summarx Summaries of the data collected are presented in Table 8.3. Measurements in the lab hood drain showed activity exceeding the DCGL, and two sink drains are noted to have activity measurement greater than 25% of the preliminary guideline. The lab hood drain is the drain from the lab hood in package A0003 that showed activity exceeding the DCGL. The ventilation systems did not show elevated measurements.

Since none of the soil samples showed measurable licensed radioactivity, and remediation of land areas is not expected, a DCGL for open land areas was not calculated. The site-specific DCGL for building surfaces was calculated based on the relative fraction of each radionuclide detected in the resin sample. Radionuclide specific guideline values relate activity concentrations in terms of dpm/100 cm 2 to 25 mrem/yr. A gross activity DCGL was calculated for the mixture of radionuclides using the screening values published in the Federal Register [FR Vol. 63, No. 222, 11/18/98] and values generated using the NRC DandD screening code (referenced in FR Vol. 63 No. 222) when there was no published value for the radionuclide. The screening values for DCGL were based on a conservative set of assumptions. The Federal Register notes that "Sites with building surface contamination levels below those [screening values] listed would be deemed acceptable for release for unrestricted use in accordance with the dose criteria in 10 CFR 20.1402, provided that residual radioactivity has been reduced to 'as low as reasonably achievable' (ALARA) levels." If the screening DCGL values prove to be unacceptably low, a site-specific dose model can be developed and a dose assessment performed to calculate more realistic radionuclide specific guideline values. However, based on the mixture of nuclides identified in the resin sample and the resulting gross DCGL, a site-specific dose assessment is not anticipated to be necessary. The gross DCGL calculation for building surfaces is provided in Attachment 2 to this report. Attachment 2 also includes the DandD computer runs that were generated. Table 8.10 shows the radionuclide specific screening levels and the resulting DCGL of 27,000 dpm/100 cm 2 for the resin mixture. If a lower dose criterion is used during decommissioning, then the surface DCGL will decrease proportionally. For example, if an annual dose equivalent of 15 mrem/yr is used for decommissioning, the DCGL reduces to 16,000 dpm/lOOcm 2.Table 8.10 A.J.

An estimate of activities was made for a conservative set of assumptions. Europium isotopes are frequently seen in activated concrete from impurities in the materials Eu-152 and was identified in the resin sample. The report contained in APPENDIX C does not list europium isotopes. Although soil activity is predicted, soil sampling and analysis provides the best information on the radionuclide concentrations in soil.The analysis of 34 samples taken during soil boring did not show any measurable radioactivity by gamma spectral analysis. The soil from the borings was only analyzed by gamma spectroscopy. Many of the radionuclides listed for soil in APPENDIX C are radionuclides that cannot be detected by gamma spectroscopy. Therefore, analysis of a few samples during decommissioning for these radionuclides is suggested. NUREG/CR-3474, "Long-Lived Activation Products in Reactor Materials" provides a comparison of calculated activation activities and measured activities. The measured activities (through component sampling and analysis) are consistently higher than calculations predict sometimes by as much as a factor of 21. During decommissioning sample analysis may be very different from the calculation estimate.8.12 Soil Borings and Installation of Test Wells Soil Borings An investigation was conducted to evaluate whether or not there was historical soil contamination around or underneath the reactor vessel resulting from neutron activation or tank leakage. During the HSA, discussions with reactor personnel indicated that data on make-up water required for the pool during the operation of the reactor indicated that there was no tank leakage. Three vertical soil borings were drilled at locations adjacent to the reactor vessel inside the building and one angle boring was drilled from the outside of the building to access soil from underneath the vessel. Soil samples were taken and analyzed for stratigraphy and gamma-emitting radionuclide concentrations using the on site gamma spectroscopy system.Three vertical borings (J13-1, IB-2, and 1B-3) were drilled around the reactor to depths of 36 feet (approximately 10 feet below the bottom of the reactor). The drilling method was direct-push using a Geoprobe 6610DT rig and MacroCore sampler. Initial drilling through the concrete floor at each boring location required the use of a GH60 hammer and carbide tip bit. This resulted in a 4-inch diameter hole with minimal dust/debris generated. After the drill bit was Revision 0 62 of 69 advanced through the concrete floor, the remainder of drilling involved hydraulic push of the sampler through the soil. The sample tube was advanced 4 feet at a time, and a continuous sample throughout the soil column was obtained. The diameter of soil boring was approximately 2 1/2-inches O.D.The continuous sample cores were logged for geological information and then split approximately every 2 feet to obtain composite samples for radiological parameters. Each sample was initially screened for radioactivity using a Ludlum Model 177 Frisker with a GM Pancake Probe. The samples were then processed in accordance with Section 5.3 of Duratek Procedure REDS-CHR-107, Subsurface Soil Sampling.After sampling, the holes were grouted using bentonite and a concrete cap at the surface. Diesel exhaust from the Geoprobe was vented to the outside via the vent fan in the reactor room. Air monitoring was performed for oxygen, carbon monoxide, and Lower Explosive Limit (LEL). This air monitoring was performed at the source of the exhaust, general areas of the reactor room, and at the exhaust of the reactor-cooling pit.The angle boring (EB-4) was drilled from a point outside the reactor building at a 530 angle to a depth of 88 feet. This boring was used to obtain soil samples below the reactor. Procedures for obtaining this sample were basically the same as those mentioned above for vertical borings. Samples for analysis were taken as follows: one composite sample for gamma spectral analysis was taken every 10 feet for the first 60 feet then every 4 feet thereafter until reaching approximately 5 feet beyond the far side of the reactor tank.The soil boring logs with a description of the stratigraphy and results of the radiological field screening are presented in APPENDIX D to this report.Radionuclides other than naturally occurring radionuclides were not detected by analysis of the soil samples by gamma spectroscopy. A summary of the gamma spectral analysis results is contained in Attachment 9 to this report. This supports the operational history data that there was no tank leakage, and therefore no contamination of the soils surrounding the reactor vessel at the sample points monitored. Groundwater Flow Study An investigation was conducted to evaluate whether or not there is a measurable impact by the reactor on the groundwater directly beneath the facility. To accomplish this goal, three soil borings were drilled and installed with monitoring wells. Groundwater samples were subsequently taken and groundwater flow direction was determined. Revision 0 63 of 69 Three soil borings (EB-l, EB-2 and EB-3) were drilled outside the VA Medical Center facility at preselected locations (Figure 1 of APPENDIX D). The locations were cleared for the presence of utilities prior to drilling. The borings were advanced until a significant geological confining unit (glacial till) was encountered using 41/4-inch I.D. hollow stem augers. The total depths of the borings were 131 feet for EB-1, 110 feet for EB-2, and 100 feet for EB-3. Soil core samples were obtained using a split-spoon sampler. Samples were obtained at 5-foot intervals for the first 50 feet of drilling and at 10-foot intervals at depths greater than 50 feet below ground surface. The sampler was decontaminated between samples.After the samples were taken from the split-spoon sampler they were analyzed for stratigraphy by a geologist and were screened by a health physicist for radiological parameters. Certain soil samples were composited in the field for subsequent gamma spectral analyses. The soil boring logs with a description of the stratigraphy and results of the radiological field screening are presented in APPENDIX D.After each boring was completed and samples taken, a 2-inch diameter PVC monitoring well was installed. Each well was equipped with a 10 -foot long PVC screen. Filter pack sand was placed around the screen and a bentonite seal was placed directly above the sand. Above the bentonite was placed Portland cement grout to the ground surface. Each well was completed using a flush-mount manhole and lockable cap. Monitoring well construction details are shown in APPENDIX D. Auger cuttings were placed in one cubic yard containers and moved off-site for disposal.Each well was installed. The groundwater gradient was determined by measuring the depth of the groundwater in each well and the distance between the wells.Stratigraphs The site is covered by approximately 3 feet of fill material. The fill material consists of firm, moist, light brown silty clay sediments with intermixed fine sand and rust stains. The fill material is underlain by Peoria Loess depositions. Peoria Loess depositions consist mostly of medium- stiff, moist, low plasticity silty clay with iron and calcium nodules. The thickness of Peoria Loess depositions is 34 to 34.5 feet.Peoria Loess is underlain by Loveland Loess depositions. Loveland Loess depositions consist mostly of medium-stiff, moist, medium-plastic, reddish-brown silty clay with iron and manganese nodules. The thickness of these depositions were 97 feet, 74.5 feet, and 65.5 feet at locations EB-1, EB-2 and EB-3 respectively. Revision 0 64 of 69 Loveland Loess is underlain by glacial till that consisted of very stiff, moist, medium-plastic, gray, silty clay with some gravel.Groundwater Flow Direction Relative elevations of tops of groundwater monitoring well casings (TOCs) were obtained from field survey. Relative elevations of water table were determined on the basis of relative elevations of TOCs and water levels measured from TOCs after monitoring well development. Groundwater is generally encountered in the Loess with a flow to the westward direction. The hydraulic gradient is approximately 0.01 ftlt.Relative elevations of water table and direction of groundwater flow are presented in Figure 1 of APPENDIX D.8.13 Asbestos and Lead Sampling Fifteen field screen chemical tests and three scraping samples were taken to evaluate for the presence of lead in paint. Eight samples were taken to evaluate the presence of asbestos. Asbestos samples showed asbestos in the lab counters, fume hood panels, floor tiles, pipe insulation, and in the floor tile mastic adhesive.Paint samples from the three paint locations (beige paint from dumbwaiter frame, beige paint from the south stairwell door frame, and beige paint from the south east corner column) all showed measurable lead ranging from 0.66 to 1.068 %lead by weight. Two of these samples exceeded the limit of 0.5% lead by weight established in the Lead-Based Paint Poisoning Prevention Act of 1971, as amended by the Housing and Community Development Act of 1987. Both of the positive lead samples were taken on painted metal and typical of older metal primers. Results are provided in Attachment 10.Revision 0 65 of 69 9.0 DATA QUALITY ASSESSMENT, QUALITY ASSURANCE AND QUALITY CONTROL Once all the surveys were complete, the data was assessed and evaluated to ensure that all the requirements of this characterization plan and the QAPP were met and the data are acceptable. Duratek's Quality Assurance/Quality Control Programs ensure that all quality and regulatory requirements are satisfied. All activities affecting quality were controlled by procedures and plans. The plans and procedures included the following Quality Control measures as an integral part of the survey process.9.1 Selection of Personnel Project management and supervisory personnel were required to have extensive experience with Duratek procedures and be familiar with the requirements of MARSSIM and the Survey and Sampling Plan. Management had prior experience with the radionuclide(s) of concern and a working knowledge of the instruments used to detect the radionuclides on site. Project management and supervision were required to maintain OSHA safety qualifications as safety is a primary concern of Duratek.Duratek selected supervisory personnel to direct the survey based upon their experience and familiarity with the survey procedures and processes. Likewise, Health Physics technicians who will perform the surveys were selected based upon their qualifications and experience. 9.2 Training All project personnel received site-specific training to identify the specific hazards present in the work and survey areas. Training included a briefing and review of the plans and Duratek procedures. During site orientation and training, survey personnel became familiar with site emergency procedures. 9.3 Written Procedures All survey tasks essential to survey data quality were controlled by procedures and the written plans.9.4 Instrumentation Selection, Calibration and Operation Duratek selected instruments proven to reliably detect the radionuclides present at the facility. Instruments were calibrated by Duratek or qualified vendors under approved procedures using calibration sources traceable to the National Institute of Standards and Technology (NIST).Revision 0 66 of 69 All instruments and detectors were inspected and source checked daily when in use to verify proper operation. Control charts and/or source check criteria were established at the beginning of the project for reference. Procedures for calibration, maintenance, accountability, operation, and quality control of radiation detection instruments implement the guidelines established in American National Standard Institute (ANSI) standard ANSI N323-1978 and ANSI N42.17A-1989. 9.5 Survey Documentation Survey packages were the primary method of controlling and tracking the hard copy records of survey results. Records of surveys were documented and maintained in the survey package for each area according to Duratek procedures. Each survey measurement was identified by the date, technician, instrument type and serial number, detector type and serial number, location code, type of measurement, mode of instrument operation, and Quality Control (QC) sample number as applicable. 9.6 Chain of Custody Procedures establish responsibility for the custody of samples from the time of collection until results are obtained. Samples shipped off site for analysis were accompanied by a chain-of-custody record to track each sample.9.7 Records Management Generation, handling and storage of survey data packages was controlled by an approved procedure. 9.8 Duplicate Review of Survey Results The survey package and survey data from each area were reviewed by two people to verify all documentation is complete and accurate. This included the surveyor and either the project manager or his designee.Revision 0 67 of 69 10.0

SUMMARY

AND CONCLUSIONS The results of this comprehensive characterization effort show the A.J. Blotcky reactor facility to be relatively free of radiological contamination. Over 3,100 measurements and samples were obtained to characterize the facility. The building surfaces (walls, floors, and overheads) characterization showed no measurements exceeding the calculated DCGL of 27,000 dpm/l 00cm 2.The only areas where contamination is present in elevated levels above the calculated DCGL of 27,000 dpm/I00 cm 2 are: 1) Reactor pool components and the reactor vessel 2) The south lab hood in room SW2D, and 3) Drain 3 in the south lab hood of room SW2D.Measurements taken of outside areas and soils did not show activity concentrations above the detection levels required for this survey. Soil borings were made by HDR Engineering to evaluate the groundwater flow and direction, and to analyze the soil adjacent to the reactor core for gamma emitting radionuclides. Three test wells were installed to depths between 100 and 131 feet. Four additional borings (without installation of wells) were made to depths of 36 feet (approximately 10 feet below the bottom of the reactor).Eighty-eight soil samples for various depths from all seven borings were analyzed by gamma spectroscopy. None of the samples showed activity other than naturally occurring radionuclides. In addition to the soil borings, 30 surface soil and 30 subsurface soil samples were obtained during the characterization. None of the samples showed activity other than naturally occurring radionuclides. Lead paint above the standard was detected in two samples of paint taken from metal surfaces (door frarne and column). Asbestos was detected in lab counters, fume hood panels, floor tiles, pipe insulation, and in the floor tile mastic adhesive.A sample of resin was obtained from the reactor coolant demineralizer and sent to Eberline Services laboratory in Oak Ridge, Tennessee, for analysis of 10 CFR part 61 radionuclides, and other radionuclides typical of reactor activation and fission products.The sample analysis was used to calculate DCGL for the beta surface contamination levels for site decommissioning. The DCGL was developed to meet the intent of Subpart E, 10 CFR 20.1402, Radiological Criteriafor Unrestricted Use. The DCGL for gross activity measurements equivalent to the 25 mrem annual total effective dose equivalent was calculated to be 27,000 dpm/100 cm 2 for building surfaces and structures.

Release of the data contained in this hard copy data package has been authorized by the cognizant project manager or his/her designee to be accurate as verified by the following signature. I M.R. McDougall Laboratory Manage'Date: 12/18/2002 Page 7 of 7 g 77-00035 Attachment 2: Calculation of Derived Concentration Guideline Values DCGLs were calculated using guidance from section 4.3 of NUREG-1575, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM). For building surfaces it is assumed that the final status surveys used to demonstrate compliance with the criteria for release for unrestricted use will be performed with large area detectors. When only one radionuclide is present, then the site-specific DCGL is the single screening value DCGL for that radionuclide. Since the survey technique cannot provide radionuclide specific information, if more than one radionuclide is present, the site specific gross activity DCGL can be calculated using the following equation: Gross Activity DCGL =F+D L + +DCGL, DCGL 2 DCGL 3 DCGLU)Where: DCGL = the derived concentration screening value for the specific equivalent to 25 mrel/yr, (dpm/100 cm 2)F = the fraction of the radionuclide mix which is considered detectable based on the radionuclide beta yields and end-point energies relative to the radionuclide used to calibrate the detector, (unitless) f = the relative fraction of radionuclide i in the mix, (unitless) The fractional radionuclide mixture was obtained from a resin sample (VA-02-0176) analyzed at Eberline Services Laboratory. Radionuclide specific DCGLs for building surfaces were obtained from the screening values published in the Federal Register [FR Vol. 63, No. 222, 11/18/98], and values generated using the NRC DandD screening code when there was no published value for the radionuclide.
