University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 1 INTRODUCTION 1.1 Project Overview During the calendar year 2006, the University of Washington Nuclear Reactor (UWNR) underwent full decontamination and decommissioning (D&D) activities to support the termination of United States Nuclear Regulatory Commission (NRC) license R-73. D&D activities were conducted by LVI Services, Inc. (LVI) and its partner ENERCON Services, Inc. (ENERCON) in accordance with the NRC approved UWNR Decommissioning Plan (NES, 1994). The LVI team began project planning in January 2006 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 LVI team mobilized personnel to prepare the site for D&D activities. Radiological D&D activities began in early April 2006 and were conducted through the summer of 2006. The D&D activities resulted in the generation of 1677 cubic feet of Low Level Radioactive Waste and 32 cubic feet of Mixed Waste which were disposed at U.S. Ecology in Hanford, Washington and Energy Solutions in Clive, Utah, respectively. Final Status Surveys (FSS) in support of license termination commenced in August 2006 and were completed in the beginning of October 2006. FSS was planned and conducted in accordance with methodologies established in NUREG/CR-5849. 1.2 Ownership and Licensing The UWNR is wholly owned and operated by the University of Washington under NRC License Number R-73. 1.3 Object and Scope The objective and scope of this report is to document the relevant D&D activities conducted at the UWNR and to provide the FSS data results to support the request for NRC license termination. FSS data is included as Attachments 1-39. Attachments 40 and 41 present characterization sample results for the activated portions of the bioshield. Attachment 42 summarizes air sample collection results gathered during the course of remediation activities. 1 UW-MCP-OP-13 Rev. UW-MCP-OP-13 Rev. 1 I I

The historical information presented is not all-inclusive. However, it provides the best available reconstruction of activities from the data available. 2.1 Facility Location The UWNR is located within the More Hall Annex (Annex) (Figure 1) on the main campus of the University of Washington (UW) in Seattle, Washington. The Annex is located west and adjacent to the intersection of Jefferson and Mason Roads (Figure 2). The UW campus is located approximately 10 miles north of the center of the city of Seattle, Washington. Figure 1 - More Hall Annex 2 UW-MCP-OP-13 Rev. UW-MCP-OP-13 Rev. 1 I 2

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 2.2 Facility Operating History The UWNR was an ARGONAUT type training and research reactor. It began operation in April 1961 with an initial power output of 10 kilowatts. Following 6 years of intermittent use, the power was increased to 100 kilowatts in 1967. The reactor operated for training and research purposes until June 30, 1988 when critical operations were permanently shut down. During its operational years, the reactor generated a total of 303,443 kilowatt hours. Following its shutdown, all fuel was removed and sent to Idaho National Labs outside of Idaho Falls, ID for disposal. Radiological characterization activities in support of decommissioning planning began in 1993 by NES, Inc. Following the characterization, NES, Inc. prepared the UWNR Decommissioning Plan which was approved by the NRC in 1994. 2.3 Facility Radiological History The only radiological incident of historical note was a failed plutonium oscillator experiment on June 13, 1972 whereby plutonium contamination was dispersed throughout the Reactor Room. Decontamination efforts removed most of the contamination in the weeks following the incident, but characterization activities identified small amounts of alpha contamination in areas of the Reactor Room including the ventilation ductwork and overhead crane. Following the incident, the floor of the Reactor Room was painted and covered with composite tile to prevent transfer of any residual contamination. The walls of the Reactor Room were also painted and temporary wall partitions erected at some point following the plutonium incident. During its operational years, various radiological experiments were conducted in the reactor and in the adjacent rooms. Various experiments with short-lived isotopes and irradiated materials were prepared, conducted and analyzed in the Radiochemistry, Counting and Experiment Rooms. Other than the plutonium incident, no experiments using longer lived isotopes have been identified that could have deposited residual radioactivity at the site. Historically, waste disposal has occurred offsite at approved disposal facilities for all radiological materials, i.e., no onsite burial of radiological materials has occurred. Previous characterizations have not indicated the presence of any radiological contamination outside of the Reactor Room other than the retention tanks. 2.4 Facility Description The More Hall Annex is divided into two sections, the restricted and the unrestricted areas. The restricted area is located in the western half of the facility and is comprised of the Reactor Room and associated facilities. The unrestricted area is located in the eastern half of the facility and is comprised of three story structure previously used for classroom, supervisory offices, graduate study rooms, the reactor control room, fan loft and the mechanical equipment room. These building layouts are depicted in Drawings 1-3 which are located in Section 10 - Site Map Drawings. These areas outside of the Reactor Room have been generally kept free from activities involving radiological materials and have been historically maintained as unrestricted areas. The restricted and unrestricted areas are separated by a 20-cm concrete wall. 4 UW-MCP-OP-13 Rev. UW-MCP-OP-13 Rev. II 4

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 2.4.1 Reactor Room The Reactor Room and associated facilities are contained in an area approximately 14 meters in width by 21 meters in length. The Reactor Room measures approximately 14 meters long by 10 meters wide and is three stories high with an average height of 10.5 meters. Adjacent to the Reactor Room are four separate smaller rooms which include the Radiochemistry Laboratory (4 meters x 4.5 meters) and Crystal Spectroscopy Room (10 meters x 4 meters) to the south and the Counting (4 meters x 4 meters) and Experiment (6 meters x 5 meters) Rooms to the north. Each of these side rooms are approximately 3 meters in height. The floor and walls of the Reactor Room are poured concrete. The floors are between 15-cm and 45-cm thick and were poured over undisturbed earth. The exterior walls are 25-cm thick to a height of 4 meters above the floor. The upper surfaces of the Reactor Room are supported by a concrete column and beam structure and contain glass windows midway between the floor and ceiling. The north, west and south walls of the Reactor Room are below grade as the Annex is built into the side of a hill. The Reactor Room is isolated from the unrestricted areas of the building by a 20-cm concrete wall. Two doorways along the eastern wall provide access to Reactor Room; a single door from the control office, and a double door from the Robotics Laboratory. Direct access to Reactor Room is also available through a hatchway from the Mechanical Equipment Room, and two emergency egress hatchways located on the north wall of the Experiment Room and the south wall of the Crystal Spectroscopy Room. The Reactor Room contains four distinct features: the reactor monolith, the process pit, the fuel storage pit and the overhead bridge crane. 2.4.1.1 Reactor Monolith The reactor monolith is situated in the center of the Reactor Room. The concrete monolith is comprised of two concrete biological shields (bioshields), spaced 1.5 meters apart (Figure 3). Each bioshield is approximately 6 meters in length, 1-3 meters in width, and 3.5 meters in height. The reactor core, graphite moderator and associated components were located in this space between the bioshields. UW-MCP-OP-13 Rev. 1 5

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 Figure 3 - Reactor Monolith 2.4.1.2 Process Pit The process pit is located directly to the south of the reactor bioshield. It is located below grade and is 2 meters wide, 4 meters long and 1.5 meters deep. Before D&D activities, it contained a sump, sump pump, reactor coolant pump, heat exchanger, waste lines, and a storage tank. Reactor coolant lines and associated lines ran from underneath the reactor to the north side of the process pit. Seven solid concrete covers are placed over the pit. The top of the concrete covers are level with the finished floor of the Reactor Room. 2.4.1.3 Fuel Storage Pit The fuel storage pit is located in the southwest corner of the Reactor Room. It contains fifty-four, 10-cm diameter steel lined storage tubes. Each tube is approximately 1.5 meters deep and was lined with plastic sleeves. Each tube contained an iron encased concrete shield plug that locked into place following placement of the fuel rods for storage. Three solid concrete covers are placed over the pit. The top of the concrete covers are level with the finished floor of the Reactor Room. 2.4.1.4 Reactor Room Ventilation Systems Ventilation systems in the Reactor Room and Crystal Spectroscopy Room provided air circulation and reactor exhaust. The ductwork in the Reactor Room was typical box and frame construction located 3 UW-MCP-OP-13 Rev. I 6

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 meters above floor level and below the windows. This ductwork transported recirculated air from filters in the Crystal Cpectroscopy Room. The reactor's 250 CFM blower transported exhaust air to a 10,000 CFM dilution fan in the Fan Loft located above the Control Room via a 12 cm diameter line along the walls of the Reactor Room. Radiological characterization activities identified the reactor ventilation ductwork as potentially contaminated due to the plutonium incident. 2.4.1.5 Overhead Bridge Crane The Reactor Room is serviced by a 3-ton capacity bridge crane. The crane has historically been used to move shield blocks into various positions about the reactor monolith and heavier objects around the reactor room. The crane spans the Reactor Room and is constructed of one large I-beam approximately 10 meters in length. 2.4.2 Unrestricted Area - First Floor The unrestricted area of the first floor is located east of the Reactor Room. This area is comprised of the Robotics Lab, Directors Office, Control Office, Calculating Room, Graduate Room and restrooms. 2.4.3 Unrestricted Area - Second Floor The second floor area is an unrestricted area located adjacent to the upper surfaces of the Reactor Room. It is comprised of the Lecture Briefing Room and the Control Room. Located above these rooms are the Mechanical Equipment Room and the Fan Loft. These areas housed the air handling systems for various building systems. 2.4.4 Underground Utilities Various underground lines are located throughout the UWNR. An investigation into the design and operating history of the facility identified various lines which transported waste liquid, potable water, steam, and electrical services. There were two drainlines identified beneath the floor of the Reactor Room that had potential for radiological contamination. These lines ran from the sink and emergency shower in the southeast comer of the Experiment Room and process pit to the Radiochemistry Lab where it tied together and drained outside the building to the retention tanks. These lines connected to a drain on the northeast comer of the bioshield and two sink drains located in the Radiochemistry Lab. Drawing 4 depicts the location of these drain lines. Drawing 4 is located in Section 10 - Site Map Drawings. 2.4.5 Exterior Building Features - Retention Tanks Two retention tanks and a valve gallery are located outside the Annex, directly south of the Radiochemistry Lab. The retention tanks were used to store overflow water from the process pit and drain lines located in the restricted areas of the building. Each retention tank is approximately 2 meters wide by 2 meters long by 2 meters deep and are constructed of sealed concrete approximately 10-cm thick. The valve gallery is located between the tanks and housed the pumps, level controls and water lines which distributed the liquids between each tank. Incoming liquids were received into the valve gallery through a 2-in cast-iron line which exited the Annex from underneath the south wall of the Radiochemistry Laboratory. Drawing 1 depicts the location of the retention tanks. Drawing 1 is located in Section 10 - Site Map Drawings. UW-MCP-OP-13 Rev. I 7

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 3 DECOMMISSIONING ACTIVITIES 3.1 Site Area Identification Drawings 1, 2 and 3 (Section 10) depict all site areas involved in the decommissioning process. Drawing 1 depicts first floor survey areas, and Drawing 2 depicts second floor survey areas. Drawing 3 depicts the Fan Loft and Mechanical Equipment Room. Building areas involved in the decommissioning process are identified on the drawings by section and survey unit, for example, a plant area identified as 3-1 would refer to Section 3, Unit 1. Sub-unit numbers are assigned as necessary to meet final status survey size requirements for affected areas so that 3-1-1 would refer to Section 3, Unit 1, Sub-Unit 1. Section numbers were assigned to various areas based on distinguishing features such as floor level and survey classification; survey unit and sub-unit designations are associated with the final status survey phase of the decommissioning process. Section numbers were assigned as follows: Table 3-1: Assigned Section Numbers Survey Section Location/Description Distinguishing Features 1 First Floor Reactor Room and other restricted areas 2 Second Floor Control and Lecture Briefing Rooms 3 Building Exterior Retention Tanks 3.2 Decontamination and Decommissioning Activities Upon mobilization, various activities were conducted to prepare the site for D&D activities. Miscellaneous equipment and materials were surveyed, released and disposed to facilitate D&D activities. 3.2.1 Facility Modifications Upon mobilization, some facility modifications were necessary to provide increased access to the Reactor Room. These modifications included removal of the walls separating the Crystal Spectroscopy Room and Experiment Room from the Reactor Room. The drywall corridor between the Control Office doorway and Experiment Room was also removed, surveyed and free released. No other walls were removed from the restricted areas. Emergency egress hatchways were modified to accommodate HEPA ventilation units and make up air supply. 3.2.2 Removal of Shield Blocks Concrete shield blocks were used during reactor operation to provide increased shielding around the reactor bioshield. These shield blocks were surveyed, decontaminated as necessary and released. Any UW-MCP-OP- 13 Rev. I 8

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 shield block material that could not be released was packaged and disposed as radiological waste. One remediated shield block was surveyed to FSS standards and left within the Reactor Room. 3.2.3 Reactor Monolith The reactor monolith consisted of two reinforced concrete bioshields on the north and south. The reactor core box, lead and graphite shielding and associated reactor systems were contained in the center of the monolith between a shield tank to the east and concrete shield blocks to the west. The shield blocks and shield tank were removed and surveyed. Any portions of the shield tank or shield blocks that could not be released were packaged and disposed as radiological waste. A contamination control envelope (CCE) was installed over the top and west side of the monolith with HEPA ventilation installed on the east side of the monolith. The graphite moderator and lead shielding blocks were removed, packaged and disposed as radiological and mixed waste. After access to the core box was available, surveys were conducted to assess the radiological conditions of the core. The core box was removed, packaged and disposed as radiological waste. After the core box and the remainder of the lead and graphite were removed, demolition commenced on the activated concrete contained within the monolith using a Brokk remote demolition tool and hand tools. As the demolition progressed, periodic surveys were conducted to identify surfaces requiring additional demolition to meet the acceptance criteria. Concurrent with the demolition activities, the six steel beam tubes were cut and removed from the monolith as well as any remaining peripheral equipment. 3.2.4 Fuel Storage Pit The fuel storage pit is located in the southwest comer of the Reactor Room and consists of fifty-four steel-lined tubes which are embedded in concrete. Each tube contained removable shield plugs and plastic liners. The shield plugs and liners were removed, surveyed and released or disposed as radiological waste as necessary. Each tube was surveyed according to the survey protocol established in the Decommissioning Plan. Each tube was surveyed via 100% scan for beta-gamma and alpha activity. Additionally, five static readings, two gross alpha and beta-gamma wipes and one liquid scintillation wipe, which was counted for low energy beta activity (I3), were taken in each tube. Decontamination activities involved removing the paint from the top of the fuel storage pits. Tube A2-9 was identified as having alpha activity greater than the guideline limit and was remediated. A map showing the location of this tube is available in Attachment 6. 3.2.5 Process Pit The process pit contained a sump, sump pump, reactor coolant pump, heat exchanger, holding tank and waste lines. The equipment was removed from the pit and disposed as either clean waste or radiological waste based on total contamination surveys. The pit walls, floor, and sump were wiped down and surveyed. Areas with elevated activity were remediated in preparation for final status surveys. UW-MCP-OP-13 Rev. 1 9

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 3.2.6 Reactor Room The Reactor Room housed the reactor monolith, process pit, fuel storage pit, overhead bridge crane, and Reactor Room ventilation systems. There was ventilation ductwork which encompassed the entire room, and was mounted to the walls just under the windows. All supply and return ductwork in the Reactor Room were entirely removed, including the 12 cm diameter line transporting reactor exhaust air to the dilution fan, and disposed based on the survey results. 3.2.7 Overhead Crane D&D activities identified low levels of alpha contamination on the overhead bridge crane. These areas were remediated using abrasive measures and wiped down. Portions of the overhead crane including the catwalk, motor, and pulley system could not be surveyed due to inaccessibility and were consequently removed and disposed as Low Level Radioactive Waste (LLRW). 3.2.8 Removal of Wall and Floor Coatings During D&D activities, various wall and floor coatings were identified that either were or could have been applied after the reactor began operation. While the potential for contamination of these areas from reactor operations was low, any coatings in the Reactor Room that were applied after the plutonium incident were removed. Residual floor paint, applied to fix contamination from the plutonium incident, was removed by grinding. A layer of lead based paint, applied to the top surface of each bioshields after the plutonium incident, was removed and disposed as mixed waste. During building construction, a layer of asbestos skimcoat was applied to the lower walls of the Reactor Room and the four adjacent rooms. Through discussions with operation staff, it was determined that a layer of paint was applied over the top of the skimcoat after the plutonium incident, which required the paint on all of the walls of the Reactor Room and side rooms to be removed. Containments were constructed and all outer wall paint was removed with grinders from the Reactor Room floor to the ceiling. This material was disposed as Asbestos Containing Materials (ACM) contaminated LLRW. In effect, all wall coatings in the Reactor Room and adjacent rooms were removed, including original surfaces applied before operations began. 3.2.9 Peripheral Rooms There are four peripheral rooms within the Radiologically Controlled Area (RCA) adjacent to the reactor room. These are the:

             "   Counting Room

• Experiment Room
• Radiochemistry Laboratory
• Crystal Spectroscopy Room These rooms contained support equipment and systems such as the secondary cooling system, fume hoods and sinks, and drain lines. All of the fixed and loose equipment in these rooms was removed with the exception of piping in the overhead of the Crystal Spectroscopy Room. The materials were surveyed and disposed according to the survey results. The overhead piping was left in place because it consisted of hot and cold water supply and did not transport process water. A diagram and photograph depicted the overhead piping configuration are included in Attachment 25. Additional decontamination was performed in the Crystal Spectroscopy Room on the floor. Other discreet areas identified as having elevated activity were remediated and surveyed.

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 3.2.10 Retention Tanks The retention tanks are located outside the south end of the More Hall Annex. Scoping surveys identified low levels of discrete elevated activity within the tanks. Hand wiping successfully removed the elevated activity and the tanks were cleaned in preparation for FSS. The center section between the tanks is the valve gallery which contained piping, a pump and valves to control the tank levels. Much of the piping and valves were removed to facilitate FSS. Equipment and materials were surveyed and disposed based on the survey results. 3.2.11 Investigation and Removal of Underground Drainlines The presence of detectable radiological activity in the retention tanks required an investigation of the upstream drain lines which fed into the retention tanks. Drawing 4 presents the layout of the underground drain line system. The drain line which entered the retention tanks system was excavated and removed to its junction with the south wall of the More Hall Anmex. A lxI Nal probe was attached to a pipe snake and used to survey the interior of the upstream sections of drainline in the radiochemistry lab. This survey indicated the presence of elevated gamma activity at a few spots inside the pipe beneath the radiochemistry lab. Consequently, the drain lines in the radiochemistry lab were excavated and disposed as LLRW. Both sink drains were also removed. Two sections of drain line ran into the radiochemistry lab: one from the process pit and the other from the sink and emergency shower in the southeast corner of the Experiment Room. The entire section of drainline between the process pit and the Radiochemistry Lab could not be adequately surveyed due to bends and obstructions, therefore, it was excavated and removed. Inaccessible portions of drainline between the Experiment Room and Radiochemistry Lab were also removed. The drain located on the northeast corner of the reactor monolith was also removed. A twenty-eight foot straight section of drainline on the eastern side of the Reactor Room was left in place because it had no visual breakages and no drain line tie-ins. No detectable activity was found inside this section of pipe. 3.2.12 Confirmatory Soil Sampling Following drain line removal, soil samples were collected beneath the excavated pipes at elbows and couplings and analyzed for gamma emitting radionuclides to determine if any leaks had occurred which could have contaminated the underlying soils. Drawing 5 presents the layout of the underground drain line system and the locations where soil samples were collected. Samples results indicate that no detectable radionuclides other than Naturally Occurring Radiological Materials (NORM) were present in soils located beneath the drainlines within the building footprint. Two samples, SS-1 and SS- 11, were collected from soils outside the building and indicated low levels of Cs-137 which are consistent with background concentrations identified in the Radiological Characterization Report. Attachment 39 presents the results of the soils sample analysis. From this data, it has been concluded that soils beneath the UWNR drain lines were not radiologically impacted from reactor operations. 11 UW-MCP-OP-13 Rev. UW-MCP-OP-13 Rev. II I1I

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 3.3 Decontamination Methods A variety of safe and effective decontamination methods were used to meet unrestricted use criteria. The decontamination techniques employed are widely used in the decommissioning industry and do not pose unusual, or significant, health and safety concerns. 3.3.1 HEPA Vacuum High Efficiency Particulate Air (HEPA) vacuuming was used to collect dirt and larger particle debris that were contamninated with radioactive material. Although not generally effective as an initial decontamination technique, HEPA vacuuming is extremely effective in conjunction with any of the more aggressive methods of decontamination. 3.3.2 Chemical Cleaning Commercially available chemical agents were used when non-destructive decontamination was desired. These agents work by loosening or dissolving the host material and/or the contaminant. Chemical agents were used when it was reasonably assured the radioactive waste could be significantly reduced by removal of the residual contamination. 3.3.3 Grinding/Scarifying Grinding and scarifying incorporates a high-speed wheel made of stone or steel that aggressively abrades the surface to remove residual radioactive material. This method was used successfully on floors and walls where the aesthetics of the remaining surface was not a concern. A close-capture HEPA vacuum or enclosure was used with this method to capture airborne particulates for dust and airborne radioactive material exposure control. Water was also used to limit dust and maintain contamination control. 3.3.4 Demolition Demolition is often the most cost-effective solution when radioactive disposal rates are reasonable. Demolition of certain building components was used in areas where decontamination was not effective, proved to be cost prohibitive, or involved remediation of volumetrically contaminated media (e.g. the inner portions of the bioshields). Demolition was also required in certain areas to allow access to original building surfaces for survey purposes. Demolition was limited to non-load bearing building components. UW-MCP-OP-13 Rev.

All work evolutions with the potential to generate airborne radioactivity were monitored with air sampling equipment. Air samples collected over the course of the project were analyzed and the results demonstrated that average airborne activity was kept to less than 2% of the federal regulatory limit. A summary of air sampling data from project work evolutions is available in Attachment 42 - Summary of Air Sample Results. All site radiation workers were monitored with external dosimetry. The Decommissioning Plan estimated the minimum and maximum collective dose to be 4.93 and 6.02 person Roentgen Equivalent Man (REM) respectively. The total collective dose for the project was 1.491 person REM or 30% of the minimum estimate. The highest individual dose for the duration of the project was 0.323 REM. The monitoring was performed from April 1, 2006 through September 12, 2006. In addition, project personnel with potential for internal exposures were monitored through in vivo (bioassay) and/or in vitro (Whole Body Counting) means.

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 5 FINAL STATUS SURVEY OVERVIEW 5.1 Decontamination and FSS Objectives The purpose of the FSS activities is to demonstrate that the radiological conditions at the UWNR satisfy the USNRC guidelines and the UWNR can, therefore, be released from USNRC license Number R-73 for future use without radiological controls. For the purpose of this demonstration, each survey unit is independently evaluated. The objective of the survey is to demonstrate at a 95% minimum level of confidence that the license release conditions have been met. 5.2 Management Approach The present day management at the UWNR has fully supported efforts by the contractor to remediate known areas of residual contamination. Radiological Control Staff at the UWNR maintained overall responsibility and authority for the remediation activities. Qualified LVI remediation workers and ENERCON radiological control technician (RCTs) worked under the direction of the LVI/ENERCON management staff. Cooperative discussions between the associated parties resulted in a cost efficient approach to decommissioning while adhering to all applicable health, safety and radiation protection guidelines. Guidance documentation issued by the NRC was utilized as a basis for development of the final survey methodology and associated documentation. All survey methods and QA/QC activities have been and continue to be subject to review by the University staff that maintains final approval, authority and responsibility for work conducted under this license. 5.3 Instrumentation Instruments were selected that provided an adequate response to radionuclides of concern presented in Section 5.4. Minimum detectable activity (MDA) was calculated for each model. The MDA was calculated using formulae contained within the Multi Agency Radiation Survey and Site Investigation Manual (MARSSIM) and shown in Section 4.5.3. The MARSSIM contains the most current guidance on recommended methods of calculating survey instrument MDA. The background rate and detector efficiency used in the MDA are averages calculated from the daily operational check of each instrument. Table 4-1 shows the instrument models selected and summarizes the typical observed background counts in counts per minute (cpm), typical observed detector efficiency, and a typical observed MDA in disintegration per minute (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. 14 UW-MCP-OP-13 Rev.

Surface scans were performed over 100% of the surface area in the General Affected and Alpha Affected areas. Alpha and Beta scan surveys were performed at a probe to surface distance as close as practical, not to exceed 1-cm (1/2/2 inch). In the Alpha Affected areas, scanning differed from that of beta and gamma emitters in that the typical background count rate was usually very close to zero. Therefore the scan MDA for alpha activity is typically presented as a probability that a given contamination level is detectable at a given scan rate. 15 UW-MCP-OP-13 Rev. Rev. II 15

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 Table 5-2 provides a summary of the alpha detection probability using formula 6-12 presented in section 6.7.2.2 of the MARSSIM. The formula is:

                                                                                   -GEd Detection Probability (6-12)                                      P(n Ž_ 1) = I - e 61v Where P(n>1) = the probability of detecting a single count G = Contamination activity (DPM)

E = Detector efficiency (47r) d = Width of detector in the direction of the scan v = Scan speed (cmr/s) Table 5-2 Alpha Scan Probability of Detection Probability of Detecting 2 Probe Dimension in 300 DPM/lOOCM Detection Detector Type Efficiency Direction of Scan Scan Rate (Table 4-1) Alpha Gas Proportional 20.8% 9-cm 3-cm/s 96% _ _____ __ _ _____ _____ ____ (1/3 probe/sec) _ _ _ _ _ _ _ _ _ _ _ Alpha Gas Proportional 20.8% 9-cm 4.5-cm/s 88% __ ____ ___ ________________ (1/2 probe/sec) ____________ The results of this formula show that a scan speed between 1/2 and 1/3 probe width per second is sufficient to achieve the MALRSSIM recommended 90% probability of detection. A single count detected during a scan is cause for the surveyor to pause until the probability of achieving another count has reached 90%. This time interval may be calculated using formula 6-13 from the MARSSIM as presented below. 13800 Time Interval Probability (6-13) t-= CAE Where C = Maximum guideline criteria (300 dpm/100-cm 2) A = Detector Area (124-cm 2) E = 4nr Detector Efficiency (20.8%) Using this formula, a pause of 2 seconds was sufficient to achieve a 90% probability of detection. If no additional count was detected during the 2 second pause, then no elevated activity was found and the scan survey continued. The formula above as presented in the MARSSIM uses a 4-pi detector efficiency that is not adjusted for surface efficiency. Using a more conservative total efficiency, discussed in section 5.3.5, the probability of detection drops to approximately 80% for a scan rate of 1/3 probe width per second with a 3 second UW-MCP-OP-13 Rev.

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 dwell time. This is unrealistically low as evidenced by the numerous detections of alpha activity less than 300 dpm/100cm 2 demonstrated during the FSS evolution. 5.3.2 Instrument Calibration ENERCON (or another qualified vendor) calibrated all field instrumentation using approved procedures. At a minimum, the survey instruments were calibrated semi-annually. ENERCON maintained original instrument calibration data and certificates for the calibration sources at the calibration lab and provided copies to file on-site. Instrument calibrations followed NUREG-1507 and ISO 7503-1 guidance. 5.3.3 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. If a battery check failed, an equivalent size battery was installed and the instrument was rechecked before operation. An appropriate initial source response, as determined by a comparison to calibration information, to the appropriate on-site check source 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 (observed CPM for ratemeters or 10-minute static count for scalers) and a count of a known check source (observed CPM for ratemeters; 1-minute static count for scalers). If at any time an instrument exceeded its calibration due date or fell outside of the +/- 10 percent of the established initial source check, the instrument was recalibrated, and a new initial source check was performed. An inappropriate response resulted in the instrument being taken out of service and sent for calibration and/or maintenance. This information was recorded on a Daily Instrument Pre-Operational Check form. Additionally, at the conclusion of each FSS survey, the survey instrument received a response check. This response check entailed exposing the detector to an appropriate check source and verifying an acceptable count rate was obtained (i.e. within +/-10% of the initial source count). The result of this response check was documented on a survey instrument response check log. 5.3.4 Minimum Detectable Activity (MIDA) Calculation Background readings and calibration efficiencies were used to evaluate the MIDA for each instrument model.

Ei = Instrument efficiency E, = Surface efficiency (Alpha emitters = 0.25, Beta emitters = 0.5) The total instrument efficiency (Et) is a product of the instrument detection efficiency (Es) and the source detection efficiency (E,) and is used to convert the raw instrument counts into the standardized unit of disintegrations per minute (DPM). The source efficiency utilized for the UWNR follows the recommendations in ISO-7503-1 which makes recommendations for default source efficiencies. A source efficiency of 0.5 is recommended for beta emitters with maximum energies above 0.4 MeV, such as Co 60 , Eu' 52 and Eu154 . Alpha emitters and beta emitters with maximum beta energies between 0.15 and 0.4 MeV have a recommended source efficiency of 0.25, such as Pu 239 . As such, beta measurements use an E, of 0.5 and alpha measurements use an Es of 0.25. 18 UW-MCP-OP-13 Rev. UW-MCP-OP-13 Rev. 1I 18

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 5.3.6 Instrument Models The instrument models used are listed below and are typical of each instrument class. 5.3.6.1 Ludlum Model 2221 with 43-44 Air Proportional Detector This is a scaler/ratemeter instrument with a 50-cm 2 air proportional detector. This instrument was used for interior alpha surveys (scans and static locations) of pipes or other areas where the larger detectors can not be used. 5.3.6.2 Ludlum Model 2221 with 44-9 GM Tube Detector This is a scaler/ratemeter instrument with a 17.5-cm 2 Geiger-Mueller (GM) tube detector that was used for interior beta-gamma surveys (scans and static locations) of pipes or other areas where the larger detectors can not be used. The MDA calculations are based upon beta background and efficiency data. 5.3.6.3 Ludlum Model 2221/2241/2360 with 43-68 Gas Proportional Detector These are scaler/ratemeter instruments with a 126-cm 2 gas proportional detector that were used for all types of surveys. The Model 2221 may be dual-calibrated for alpha and beta detection while Models 2241 and 2360 are capable of discriminating between alpha and beta activity. For FSS surveys, specific meter/detector combinations were dedicated for either alpha and/or beta applications. 5.3.6.4 Ludlum Model 2929 with 43-10-1 Scintillation Detector This is a scaler instrument used for counting wipe samples. This instrument was used for all analysis of removable activity wipes. A 47-mm diameter cloth wipe is used to wipe over an area of 100-cm2 to collect a sample of removable activity. A wiping efficiency of 90% is used compensate for the inability of the wiping cloth to collect all the material that may be present on the surface. This instrument is capable of discriminating between alpha and beta activity. 5.3.6.5 Ludlum Model 19 MicroR This is a ratemeter instrument that was used for exposure rate surveys. It is generally accepted throughout the nuclear industry that the MIDA of this instrument is equivalent to the background readings. 5.4 Radionuclides of Concern Radionuclides of concern at the UWNR are those that have been previously reported or are anticipated based upon knowledge of historical site operations. Based upon historical site assessment, potential radiological contaminants could be present from neutron activation due to reactor operations and/or radiological spills. In the 1993 Characterization Report, activation products were identified as potential radiological contaminants in the biological shield and reactor core components. The types and inventories of these radionuclides were based upon activation analysis and similar findings during the decommissioning of the UCLA Boelter Research Reactor. These radionuclides are listed in Table 5-3. The Radiological Characterization Report for the UWNR also identified Pu-239/240 and Pu-241 resulting from the June 1972 failure of a plutonium foil experiment in the Reactor Room. Although the majority of the contamination was decontaminated immediately following the event, small amounts of alpha activity UW-MCP-OP-13 Rev. I 19

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 were identified in the characterization of the facility. This report also identified Cs-137 as potential radiological contaminant in the Radiochemistry Lab sink drain and retention tanks. Before the current reactor demolition activities began, concrete samples were collected from activated regions of the biological shield and analyzed for gamma emitting radionuclides, H-3 and C-14. As expected, these analyses identified Co-60, Eu-152, Eu-154, H-3 and C-14. Analytical results for these samples are available in Attachment 40 - Bioshield Concrete Characterization Analytical Results. During the initial D&D activities, wet smears were collected on shield blocks and various surfaces of the Reactor Room to determine if C-14 of H-3 had migrated outside the reactor core to other areas of the Reactor Room. These wet smears were analyzed on a QuantaSmart 1.31 liquid scintillation counter and no detectable activity was observed. The radiological surface release criteria for the UWNR are established in Table 1 of U.S. NRC Reg. Guide 1.86, "Termination of Operating Licenses for Nuclear Reactors" (U.S. NRC, 1974). Specifically,2 beta-gamma emitting radionuclides must not exceed 5000 disintegrations per minute (dpm)/100 cml average fixed plus removable activity. Removable activity must not exceed 1000 dpm/100 cm 2. The guidance also established alpha release criteria of 100 dpmi/100 cm 2 average fixed plus removable and 20 dprdm100 cm 2 removable. Some beta emitting radionuclides have a more restrictive release limit of 1000 dpm/100 cm 2, but none of these radionuclides are present in the UWNR. The only radionuclide from this list which would be resultant from fission would be Sr-90. There is no indication that any fuel ever leaked at the UWNR, therefore, Sr-90 was not identified as a radionuclide of concern at the UWNR. For areas of facility which possess residual tritium activity in addition to fission products, i.e., inner surfaces of the bioshield, a modified survey protocol was necessary to adequately account for all residual radioactivity. In this case, the beta-gamma survey results were used as a surrogate nuclide for tritium. A composite sample of concrete from areas within the remediated portions of the bioshield was collected at the completion of FSS activities and analyzed for gamma emitters, tritium and C-14. Analysis of this sample indicated a 1.86:1 ratio of tritium to Co-60 and Eu-152. No C-14 was detected in the analysis. Data from this analysis is presented in Attachment 41 - "Final Bioshield Analysis for Hard to Detect Radionuclides". Using the ratio above, the beta-gamma DCGL for the bioshield data analysis was reduced to 1700 dpm/1OOcm 2 to account for the presence of tritium. This surrogate assures tritium activity to be less than an limit of 5000 dpm/100cm 2 established for beta emitters in the Decommissioning Plan. Additional discussion of the affect of tritium on the final data analysis is included in Section 7.1.3.16.

NRC has stated that beta-gamma and alpha surveys should be conducted in the Reactor Room to account for Pu-241 beta decay and the alpha decay of Pu-239 and Am-241. Based upon this requirement and the list of potential radionuclides, the Reg. Guide 1.86 limits of 100 dpm/100 cm 2 alpha and 5,000 dpm/100 cm 2 beta-gamma activities are deemed suitable for the UWNR. The beta limit of 1,000 dpm/OOcm2 is not appropriate for this facility because, as established above, Sr-90 should not be present at the UWNR. For areas of the facility that contain tritium, i.e., the inner bioshield surfaces, a modified release limit of 1700 dpm/10Ocm2 average beta-gamma will be used. Table 5-2, "Potential Isotopes at the UWNR", provides the isotope list contained in the University of Washington Nuclear Reactor Decommissioning Plan. The remaining isotope of concern is Plutonium-241 as stated in the NRC position letter in Attachment B of the radiological Characterization Report. The release criteria are summarized in Table 5-4, "UWNR Decommissioning Release Criteria".

This was accomplished by performing surveys of at least three additional static measurements within the one square meter area and calculating a2 weighted average activity as described in NUREG/CR-5849. If the weighted average activity over 1-im UW-MCP-OP-13 Rev. I 21

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 is less than the guideline limit, the area meets unrestricted release criteria. If the 1-m2 weighted average was greater than the guideline limit, further decontamination was necessary. This report verifies that unrestricted release criteria have been met for the facility. Building surfaces have been evaluated against the following unrestricted release criteria:

• Fixed alpha activity does not exceed an average of 100 dpnl100 cm 2 above background when averaged over 1-IM 2.
• Fixed beta/gamma activity does not exceed an average of 5,000 dpm/100 cm 2 above background when averaged over 1 M2.

       "   Removable alpha activity does not exceed 20 dpilTlOO cm2 above background at any location.

• Removable beta/gamma activity does not exceed 1,000 dpm/100 cm 2 above background at any location.
• Gamma exposure rate of 5-microrem per hour ([tR/hr) above background at 1 meter from a surface averaged over a 100 m2 for inside floor surfaces. (Walls and ceilings were not surveyed for gamma exposure) 5.5.1 Area Classification Area classification was performed considering that all areas of the site did not have the same potential for residual contamination and did not need the same level of survey coverage to achieve the established release criteria. Classification required areas with higher potential for contamination to receive a higher degree of survey effort. For purposes of establishing the sampling and measurement frequency and pattern, NTJREG/CR-5849 uses two classifications, affected and unaffected. Due to the Plutonium foil incident, it was determined that only specific areas were suspect for alpha contamination. Therefore, the affected classification was further divided into alpha affected and general affected.

Affected areas are areas with potential or known radioactive contamination based on plant operating history or preliminary radiological surveys. This included areas where radioactive materials were used and/or stored, where spills or unusual occurrences may have resulted in the spread of contamination and areas immediately surrounding or adjacent to these locations. Affected and Unaffected areas are discussed in further detail below. 5.5.1.1 Affected Areas Affected areas are defined by NUREG/CR-5849 as "areas that have potential radioactive contamination (based on plant operating history) or known radioactive contamination (based on past or preliminary radiological surveillance)." NUREG/CR-5849 goes on to further define those areas directly adjacent to affected areas as affected based on potential contamination migration. Adjacent areas may be classified as unaffected if a physical, impermeable barrier is currently in place and was present during operations. An example would be a concrete or brick wall structure. The maximum size for a survey unit classified as affected is 100-M2 . There are two sub-divisions of affected for the UWNR Decommissioning project, which depend upon the relationship of the area to the plutonium foil incident. Areas that were impacted by the reactor operation, but not by the foil incident are classified as "general affected". Areas that were UW-MCP-OP-13 Rev. I 22

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 identified during the characterization surveys to have alpha contamination in excess of 25% of the established release criteria or that were directly impacted by the plutonium foil incident were classified as "alpha affected. 5.5.1.2 Unaffected Areas Unaffected areas are defined by NUREG/CR-5849 as "All areas not classified as affected". At a minimum, all areas adjacent to an affected area were also classified as affected unless separated by a permanent barrier, when they were classified as unaffected. Upper surfaces within an affected area were classified as unaffected barring a reason to be classified as affected. Areas separated from an affected area by an unaffected area were defined as unaffected and not requiring survey. There is no maximum size for an unaffected area. 5.5.2 Survey Requirements Survey requirements for each area was determined by the classification, as defined above. Table 5-5, "UW-MHA Survey Requirements' summarizes the survey types and density given for each classification.

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 5.5.3 Reference Grids Grid pattern were established at the site to facilitate systematic selection of measuring/sampling locations; to provide a mechanism for referencing a measurement/sample back to a specific location so that the same survey point can be relocated and to provide a convenient means for determining average activity levels. A grid consists of a system of intersecting lines, referenced to a fixed site location or benchmark. Typically, the grid lines are arranged in a perpendicular pattern, dividing the survey location into squares of equal area. Grid patterns were identified using a Cartesian Alpha-Numeric coordinate system (XY) where AO is the southwest-most corner of the floor for each unit or subunit and the lower left-hand corner of any wall in a unit or subunit. On floors, the x-axis runs east-west and the y-axis runs north-south. On walls, the axes match the grid established for the floor resulting in the floor grid wrapping onto the walls. All measurements are in meters. Ceiling surfaces utilized a superimposition of the floor grid system to readily identify survey locations. For example, grid location B2 on the ceiling was directly above grid location B2 on the floor. Partial grids, i.e. grids less than 1-m in at least one direction, are evaluated individually. Normally an area less than 0.5-rn is attached to the previous grid block and one greater than 0.5-m is designated as a new grid block. To facilitate survey design and assure that the number of survey data points from an area was sufficient to enable statistical evaluation, areas were divided into survey units or sub-units (as appropriate) that have common history, other common characteristics, or are naturally distinguishable from other portions of the site. Survey units could combine adjacent rooms or areas that have the same contamination potential. To account for the possibility of combining adjacent rooms or areas into a unit, subunit designations are used. A subunit is the smallest unique area of a unit having the same potential for contamination. Typically, a subunit is a room within a survey unit that has a distinct grid system. The location of any grid can be located by identifying the Section number, Unit number, and Sub-unit number for that grid. Typical nomenclature is as follows: Section # - Survey Unit # - Sub-unit # Where: Section Number = 1 through 3 as identified above Survey Unit Number = 1 through x (where x varies by section) Sub-unit Number = 1 through y (where y varies by unit) For example, Grid 3-13-2 is in Section 3, in Unit 13 in Sub-unit 2. Instances where the sub-unit is absent is an indication that the unit is sufficiently small to be evaluated in its' entirety. 5.5.3.1 Lower Surfaces Lower surfaces are defined as floors and walls up to 2-meter height. This would include structural supports, doors, windows, and any other item or structural member present within that 2-meter area. UW-MCP-OP- 13 Rev. 1 24

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 5.5.3.2 Upper Surfaces Upper surfaces are defined as those surfaces above 2-meter height. In general, upper surfaces within an unaffected area are exempt from survey requirements. Upper surfaces within an affected area may be classified as either affected or unaffected depending on the contamination potential. For project purposes, any upper surface within an affected area will be considered unaffected unless survey results or process knowledge indicate a need for reclassification. Data set analysis for some affected surfaces show that the surface area exceeds 100-m 2 , the maximum allowable by NUREG-5849. In these areas, the data sets are further delineated using sub-unit designators and individually analyzed for compliance with the requirements of NUREG-5849 and the license release criteria. 5.6 Background Level Determination Instrument background readings were taken each day and are used to adjust the final status survey data in order to provide a net activity. 5.7 FSS Survey Methods A description of each of the FSS survey methods is presented below. 5.7.1 Static measurement A two-minute fixed point measurement was collected for total alpha and/or beta-gamma activity at each selected location. For this survey type, the probe was placed on the selected surface and left in place while the instrument collected count data for the pre-set time of two minutes at which point the instrument signaled completion of the data collection with an audible tone. 5.7.2 Scan This consisted of a slow scan of the selected area or item for total alpha and/or beta-gamma activity with the detector as close as practical to the surface. Scan rates were dependent on the type of survey being performed. A scan for alpha and beta-gamma emitters was performed at 1/3 probe-width per second. A scan for only beta-gamma emitters was done at one probe-width per second. Scan rates were calculated based upon the formula presented into section 5.3.3. 5.7.3 Removable Activity Wipe Removable activity wipes were collected at each location with a 47-mm diameter cloth wipe and was2 analyzed on-site using the Ludlum Model 2929 counters. To perform the wipe test for FSS, the 100-cm area which received the static measurement was wiped with the cloth using moderate pressure. Removable activity wipes were collected to assess the activity of the low energy beta emitters C-14 and H-3. To perform the wipe test, a 100-cm 2 area was wiped with the scintillation wipe using moderate pressure. The wipe was dissolved in a scintillation cocktail and counted using a QuantaSmartTM liquid scintillation counter. UW-MCP-OP-13 Rev. 1 25

20. Scan or photocopy the survey package and staple each package together.

21. Proceed to the next survey.

5.7.6 Floor Drains and Embedded Pipe Floor drains and portions of embedded pipe which remained following remediation were surveyed using a procedure equivalent to that used at the UCLA Boelter Reactor decommissioning. Specifically, direct measurements, scans, and removable activity wipes were collected at each access point using appropriate FSS instrumentation. Interior surfaces were swabbed using an absorbent cloth and counted using field instruments and with the wipe counters. All measurement results were less than the guideline limits. 5.7.7 Excavations When a drainline was excavated, soil samples and/or direct gross gamma scan measurements were conducted in the open excavation. All gamma scan results corresponded to background levels. Eleven soil samples were collected from selected areas beneath the removed drainlines for volumetric analysis. There is no applicable release guideline limits established for either the gross gamma measurements or the volumetric samples, but the information was collected to provide a substantial indication that the drainline did not have any leaks throughout its operational lifespan.

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 6 FINAL STATUS SURVEY EVALUATION 6.1 Statistical Analysis FSS data was evaluated relative to conditions established for unrestricted release in USNRC License R-73. This included organization of collected data into data sets, and analysis of each data set using methods described in NUREG/CR-5849. For comparison to guideline values, the FSS data was organized into units, taking into consideration physical location, size, and classification to meet criteria described in NUREG/CR-5849. Each data set from each unit was evaluated using three statistical tests. An area that passed the three statistical tests is considered to have met the unrestricted release criteria for the facility. In the first test, the size of the data set was checked to determine if it was of sufficient size to demonstrate compliance. The number of data points required was determined using the formula 8-21 in NUREG/ CR-5849 along with the guideline value, the data set mean value, and the standard deviation. If the number of data points was less than required, then additional measurements would be required to demonstrate compliance. The second test compared individual measurements directly against the appropriate guideline value. If the elevated activity of an area was between the guideline value and the allowed maximum value, additional testing would be required to assure that the average surface activity level within the contiguous 1-IM 2 area containing the elevated area is less than the guideline value. Residual activity exceeding the maximum value limit would require remediation and follow-up surveys. Finally, a test was performed to confirm that the data met the guidelines at the 95% confidence level. For this test the means and standard deviations of each data set were determined for each radiological parameter. These values were used along with the actual number of individual measurements, a false positive probability of 5%, and a false negative value of 10%, to determine a value of [ta according to formula 8-13 in NUREG/CR-5849. This value was then compared to the guideline value and if it was less than the guideline, the area tested met the guideline at a 95% confidence level. An additional test was performed for unaffected areas. For these areas, all individual measurements were checked to determine if the values were less than 25% of the guideline. Any unaffected area that exceeded the 25% value would be reclassified as affected. When the data sets for a unit were determined to pass each of these statistical tests, the unit met the release criteria. If the data set failed to pass the statistical tests, the cause of the failure would be evaluated. 6.2 Data Preparation Prior to performing any statistical analysis on the collected survey data, it must first be converted into standardized units over a standardized area. Typically this is to net disintegrations per minute per 100 square centimeters (DPM/1OOcm 2). This is a straight-forward conversion following industry standard techniques done by utilizing the total efficiency formula in section 5.3.4 and correcting for the detection area of the instrument probe. Therefore, the completed formula for handheld field instruments is: UW-MCP-OP-13 Rev. I 29

This unit was divided into two sub-units in order to meet size restrictions for an affected area. 7.1.2.1 Sub-Unit 1-2-1 Experiment Room Ceiling, East and North Walls The Experiment Room ceiling, east and north walls were grouped together as a sub-unit for statistical analysis. This sub-unit is approximately 63-mr2 in surface area. Since no floor surfaces are within this sub-unit, no exposure rate measurements were taken. All survey results in this unit are less than the guideline limits. FSS results and a statistical sumnnary are provided in Attachment 2. 7.1.2.2 Sub-Unit 1-2-2 Experiment Room Floor, South and West Walls The Experiment Room floor, south and west walls were grouped together as a sub-unit for statistical analysis.

FSS results and a statistical summary are provided in Attachment 3. 7.1.3 Unit 1-3 Reactor Room The Reactor Room is located on the ground floor in the center of the building and was classified as alpha affected. It is the largest room in the facility and measures approximately 14-m by 10-m in size and is approximately 10.5-m high. As part of the remediation and in preparation for FSS, the north partition wall separating the Experiment Room from the Reactor Room and the south partition wall separating the Reactor Room from the Crystal Spectroscopy Room were removed, leaving only the original concrete archways. This unit was divided into 18 sub-units in order to meet the 100-mi2 size restriction for an affected area. 7.1.3.1 Sub-Unit 1-3-1 Overhead Crane The portions of the overhead crane remaining after remediation were grouped together as a sub-unit for statistical analysis. Fifty-two survey locations were identified on all of the crane surfaces which included the fixed travel rails on the north and south ends of the Reactor Room and the mobile bridge that spanned the travel rails. The movable lifting trolley was removed as part of the remediation. All survey results in this unit are less than the guideline limits. FSS results and a statistical summary are provided in . 7.1.3.2 Sub-Unit 1-3-2 Fuel and Process Pit Blocks Reinforced concrete blocks were used to cover the process pit and the fuel storage pits. These were grouped together as a sub-unit along with a portion of one remaining reactor shield block for statistical analysis. There were 27 survey locations for this sub-unit. Four exposure rate measurements were taken on the reactor shield block. The remaining exposure rate measurements were collected as part of the corresponding floor survey once the process pit and fuel storage pit blocks were returned to their normal positions. All survey results in this unit are less than the guideline limits. FSS results and a statistical summary are provided in Attachment 5. 7.1.3.3 Sub-Unit 1-3-3 Fuel Storage Tubes The fuel storage pit contains 54 steel lined tubes 1.5 meters in depth embedded in concrete and recessed approximately 20 cm below the Reactor Room floor surface.

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 yielded 0.6-r 2 of internal surface area. Three reinforced concrete blocks were normally in place over the storage pits. As per the Decommissioning Plan, each tube received 5 alpha and beta-gamma static counts, two alpha and beta-gamma removable surveys, one gamma exposure survey and one liquid scintillation wipe for hard to detect radionuclides. Total alpha activity for the sides of the tubes was measured with an air proportional 50-cm 2 detector. Total beta-gamma activity was collected with a 17.5-cm 2 Geiger-Mueller detector. Each tube was also scanned for total alpha and total beta-gamma activity. This scan was used to select the five locations for fixed point static measurement. A total of five locations exceeded their respective guidelines limits, but were less than the maximum guideline limits. Three locations exceeded the total alpha activity guideline of 100 dpm/100-cm 2 and two locations exceeded the total beta-gamma activity guideline of 5,000 dpm/10O-cm 2. The activity scans indicate that each area of elevated activity is less than 100-cml2 in area. The elevated areas subsequently were evaluated for weighted average activity over the internal area of the tube. In each case, the weighted average activity was deemed to meet criteria. Table 7-2 provides a summary of the elevated result and the weighted average result by location. In no case were there two elevated areas within one tube.

This sub-unit is approximately 81-M2 in surface area. While this sub-unit is classified as alpha affected, heavily remediated portions of the bioshield interior and the beam ports received surveys as general affected. Sufficient material was removed during remediation to eliminate concern of any of the plutonium incident residual activity remaining attached to the surfaces and volumetric samples of the bioshield indicated a lack of alpha emitting nuclides in the concrete. Three beam port penetrations were surveyed independently for beta-gamma and removable activity. UW-MCP-OP-13 Rev. 1 35

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 Rough surfaces within the remediated portions of the bioshield interior may have had an adverse effect on the detection efficiencies during FSS. Assurance is provided that detection efficiency was not affected by a resurvey of select locations using a smaller 17.5-cm 2 Ludlum model 44-9 Geiger-Mueller detector capable of maintaining a surface to detector distance of no greater than 1-cm. During this survey, measurement results are consistent with those obtained with the larger gas proportional Ludlum 43-68 detectors. The beta-gamma release criteria for this sub-unit and sub-unit 1-3-21 (the south bioshield) were reduced to 1700 dpm/l1OOcm 2 for total surface activity and 340 dpm/100cm 2 for removable surface activity to account for the potential presence of tritium in the bioshield concrete. Using a 1.86:1 ratio of tritium to2 2 beta-gamma emitters, the beta-gamma limit of 1700 dpm/1OOcm , would equate to 3160 dpIlrO00 cm tritium, which is below the release criteria for tritium in the Decommissioning Plan of 5000 dpnl100cm2 . Use of this criteria, which is for removable activity, is conservative in that the volumetric analysis was performed for total activity. Additional conservatism is provided through the application of the unity rule. The unity calculation is performed to assure that differing release criteria for multiple radionuclides do not result in a total contamination above release levels. This is accomplished by formula 4-3 from the MARSSIM: Unity C1 + C2 C, *1 DCGL, DCGL, DCGL, Where: C = radionuclide concentration DCGL = appropriate radionuclide release limit Applying this calculation to the release limits for beta-gamma emitters (1700 dpillo00cm 2) and tritium (5000 dpm/100cm 2) results in a unity value of 0.97, thereby assuring that a beta-gamma survey value that is equal to the reduced criteria results in true compliance to all release criteria. The calculations for the modified release criteria and unity rule are provided in Attachment 41. As a result, all survey results in this unit are less than the guideline limits. FSS results and a statistical summary are provided in 8. 7.1.3.17 Sub-Unit 1-3-21 Bioshield South Wall Including Beam Ports The surfaces of the southern half of the remaining portion of the bioshield were grouped together as a sub-unit for statistical analysis. This sub-unit is approximately 68-mi2 in surface area. While this sub-unit is classified as alpha affected, heavily remediated portions of the bioshield interior and the beam ports received surveys as general affected. Sufficient material was removed during remediation to eliminate concern of any of the plutonium incident residual activity remaining attached to the surfaces and volumetric samples of the bioshield indicated a lack of alpha emitting nuclides in the concrete. Three beam port penetrations were surveyed independently for beta-gamma and removable activity. The beta-gamma release limit for this sub-unit was also reduced to 1700 dpm/100 cm2 to account for the presence of tritium. Select locations within the remediated portions of the bioshield were surveyed with a smaller detector as was described in the above section to verify the detection efficiency was not adversely affected by the rough surfaces. All survey results in this unit are less than the guideline limits. FSS results and a statistical summary are provided in Attachment 19. 7.1.3.18 Sub-Unit 1-3-22 through 1-3-29 These Sub-Unit numbers were not utilized due to data management planning methodologies.

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492 8 FSS QUALITY ASSURANCE 8.1 Project Objective The objective of the FSS Quality Assurance section is to provide a description of the policies and procedures utilized to assure data quality in support of the decommissioning of the UWNR. 8.2 Quality Objectives The methods described in this document were utilized to ensure that the data collection and analysis achieved the Data Quality Objectives (DQOs) set forth for the UW-MHA Decommissioning. The methods employed to ensure such quality were:

• Careful planning and design of methods and procedures;
• Selection of qualified personnel and thorough training of the personnel to the procedures

             "  Audits and reviews of collected data to verify accuracy;

• Identification and correction of problems or uncertainties as they arise.

8.3 Criteria for Measurement Data The decommissioning release criteria for measurement data is based upon Regulatory Guide 1.86 'Termination of Operating Licenses for Nuclear Reactors'. 8.4 Special Training Requirements/Certification Prior to beginning work on the project, each Radiation Control Technician (RCT) received training on all pertinent project procedures. This training included, at a minimum, review of the operation of each radiological survey instrument, discussion of the QA/QC expectations, and review of the data collection and documentation procedures. The Safety and Compliance Manager documented the training on an attendance roster and retained the documentation on-site. 8.5 Documentation and Records All documentation pertinent to the final status of the UW-MHA decommissioning project was maintained on-site by the Safety and Compliance Manager. 8.6 Instrument Calibration and Frequency At a minimum, radiological instruments were calibrated: UW-MCP-OP-13 Rev. I 41

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492

• Semi-Annually
• Following any repair that may affect the calibration

             "   When the pre-operational source check is greater than +/-10% difference from the initial source response 8.7    Assessments and Response Actions 8.7.1    QA/QC Assessment Checklist Quality Assurance and Quality Control (QA/QC) checklists provided a method for assuring survey accuracy and provided a manner in which to identify and correct discrepancies. The following is the general guidance provided to the QA/QC manager to verify the proper completion of QA/QC Assessment Checklist for the UWNR decommissioning project.

1. Begin with an appropriate blank QA/QC Checklist.

2. Each checklist has a review information section that contains at a minimum QA/QC reviewer, review date, item reviewed, and an approval/rejection indicator. Ensure each of these blocks is complete, if an item does not apply, enter "N/A" in that block.

3. A section is present on each checklist that is specific to the information being examined. This section will contain block-columns for "Y", "N", "Item", and "Corrective Action / Comments"

4. In all cases, a definitive mark placed in the "Y" block-column indicates an acceptable item condition and a definitive mark in the "N" block-column indicates a deficiency condition that requires corrective action for that item.

5. Any mark placed in the acknowledgement section should be definitive in that it should not cross block boundaries and it should positively indicate which block is selected. A suggested mark would be an "X" placed within one block.

6. The "Item" block-column describes that which the reviewer is to examine and determine the acceptance or rejection thereof. In most cases, this item is strictly "Yes" or "No" and is not subject to outside conditions or reviewer opinion.

7. The "Corrective Action / Comments" block-colunm provides space for the reviewer to provide a suggested course of corrective action or it may be used to call attention to a potential future condition to be examined (i.e. "Numbers '1' and '7' appear similar on the datasheet").

8. If each line item has been satisfied (only "Y" acknowledgement blocks are marked), the checklist is approved and should receive an appropriate indicator in the approval area of the QA/QC Review Information section.

42 UW-MCP-OP-13 Rev. Rev. 1I 42

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492

9. If corrective action is necessary, complete a new checklist once all action items have been satisfied and attach the new checklist to the original. Repeat as necessary until the checklist receives an "Approved" mark.

10. File all "Approved" checklists in the UWNR QA/QC file.

8.8 QA/QC Verification Surveys QA/QC verification surveys were performed once a survey unit FSS was completed. At a minimum, one QA/QC Verification survey was performed for each survey unit as a standard practice. This was done to provide an early indication of potential problems with final status survey procedures/guidelines, instrumentation, and/or possible cross-contamination from ongoing site decontamination activities. All verification surveys were performed in accordance with the UWNR FSS Plan. Verification of final status surveys included the investigation of documentation, survey protocol, instrument calibration, and any practice associated with the collection of survey data. Verification surveys were completed by the Safety and Compliance Manager or, at the discretion of the Safety and Compliance Manager, by a different technician than performed the original survey. QA/QC verification surveys were performed on at least 5% of each survey unit. All requested information was verified complete on the surveys and all instruments were verified to be properly available for use, i.e., each instrument had received a valid daily pre-operational check. Locations within a survey unit were randomly selected for verification. The verification survey followed the same survey protocol utilized for FSS surveys. Upon completion of the verification survey, each verification location was directly compared against the original FSS location. If the QA/QC survey result was less than the final status survey result, no action was necessary. If there was a net difference within +25%, no action was required. If the net QA/QC survey result was +25% or greater, the net count differential was added to the net QA/QC survey result to calculate an adjusted net QA/QC value. If this adjusted net QA/QC value was less than unrestricted release criteria appropriate to the survey, no further action was required. If the adjusted net QA/QC result was greater than the unrestricted release criteria appropriate to the survey, "Invalid" was written on the Final Status Survey copy and in the appropriate entry of the Final Status Survey logbook along with the QA/QC reviewers' initials and date and designate locations on that survey to be resurveyed. All QA/QC verification surveys indicated the original FSS surveys to be valid and no corrective action and/or resurveys were necessary. 8.9 Data Entry and Review During data entry, all survey forms were reviewed for completeness and legibility, and survey instrumentation were reviewed to ensure a valid calibration. Any discrepancies or missing information necessitated direct communication with the originating technician for correction. If the originating technician was not available, clarification was obtained from the Safety and Compliance Manager, the on-site RSO, or the survey data was recollected. QA of the data entry was performned once the handwritten surveys had been entered into electronic versions of the form. The data entry review was performed on at least 5% of the survey records and included the following items:

• Survey Information (serial numbers, dates, unit, etc.) all corresponded to the survey original UW-MCP-OP- 13 Rev. I 43

University of Washington Final Status Survey Report More Hall Annex D&D, Project 10492

• The surface type (wall, floor, ceiling, etc.) was valid
• The grid (X, Y) represented on the survey form was present and valid
• Each reading (static measurements, scans, removable activity, etc.) on the electronic copy corresponded to the original survey
• Comments corresponded to the original survey 8.10 Completeness Review Prior to performance of the FSS statistical analysis, a completeness review was performed to verify that each surface of each survey unit had been adequately surveyed to meet density requirements set in the FSS Plan. This was accomplished by directly comparing the accumulated survey data against prepared survey maps. Any discrepancies were related to the Safety and Compliance Manager and/or the site RSO for investigation or additional survey as appropriate.

8.11 Data Analysis Data analysis was performed utilizing data spreadsheets and analysis routines developed by ENERCON specifically for the evaluation of NUREG/CR-5849 survey data. These spreadsheets have been utilized for many projects and the formulae and analysis routines have received numerous verification and validation reviews. A master database was created to manage the FSS survey data. This database provided the data source for the individual unit or sub-unit statistical analysis. Only the required survey data was placed into the spreadsheets for analysis. Survey data that was not required, such as alpha survey data collected in an unaffected area or exposure rates collected for a wall surface, was discarded from the analytical sheets, but has been retained in the master database. 44 UW-MCP-OP-13 Rev.

• All values listed in pCi/mI
• DAC values derived from 10CFR20 Appendix B Table 1, Column 3.

DAC Relation to ALl The derived air concentration (DAC) values are derived limits intended to control chronic occupational exposures. The relationship between the DAC and the ALI is given by: DAC=ALI(in pCi)/(2000 hours per working year x 60 minutes/hour x 2 x 104 ml per minute)=[ALI/2.4x10 9] pCi/ml, where 2x10 4 ml is the volume of air breathed per minute at work by "Reference Man" under working conditions of "light work." (10 CFR 20 Appendix B, pg 357, January 2006) In other words, a worker must breathe an air concentration at a level of 10% of the DAC for 2000 hours to receive 10% of the ALl for a given nuclide.}}
