SUMMARY

The University of Illinois at Urbana-Champaign (University, UIUC) Nuclear Reactor Laboratory

.(NRL) was an 80-foot by 45-foot, steel frame, concrete block building located between Green

,Street and Springfield Street on the 1,468-acre campus of the UIUC in the twin cities of Urbana and Champaign in Champaign County, Illinois. The building housed an Advanced TRIGA pool-type reactor designed and constructed by General Atomic Division of General Dynamics Corporation. The reactor operated under U.S. Nuclear Regulatory Commission (NRC)

License R-1 15.

The University discontinued operations of the Advanced TRIGA nuclear research reactor in 1998 and decided to- decommission the facility. Removal of the reactor fuel elements was accomplished in 2004. In 2007, the NRC approved the NRL Decommissioning Plan (DP) Which required complete removal of the reactor, systems, and demolition of the, facility.

In 2011, the University selected a Decontamination and Demolition (D&D) contractor to decommission the NRL in accordance with the DP. In October 2011, the D&D contractor mobilized to the site and began preparing the facility for D&D. Facility systems were isolated

-and all legacy waste was removed from the NRL. The reactor core and internals were removed in January 2012 with the subsequent removal of activated portions of the bioshield. Following removal of all auxiliary systems within the NRL, the NRL was decontaminated where necessary and a full radiologicali release survey was performed. A confirmatory survey was performed by NRC Region 3 personnel in May 2012 and the building was demolished.....

In July 201 a Final Status Survey (FSS) was conducted in the soils of thebuilding f6otprintper the NRC-approved FSS Plan. The Class 1 survey unit consisted of the exposed soils in -the building footprint and the Class 2 survey unit was the immediate area surrounding the excavation area.

University -ofIllinois Nuclear Reactor Lab D&D SER..CES' - Final Status Survey Report

2.0 INTRODUCTION

This report describes the D&D activities of the University of Illinois Nuclear Reactor Lab as well as thepurpose, scope, and technical approach used during the FSS.

2.1 Purpose -

The purpose of the FSS is to -demonstrate that the radiological conditions at~the UIUC NRL satisfy the release criteria approved in the DP; thus supporting a request to the NRC to terminate the NRL license. For the purpose of this demonstration, the area"is divided into survey units with each survey unit being independently evaluated. The objective of the evaluation is to demonstrate that the radiological release conditions have been achieved.

2.2 Project Background The NRL was an 80-foot by, 45-foot, steel frame, concrete block, building located between Green Street and Springfield Street. on the 1,468-acre campus of the UIUC in the twin cities of Urbana and Champaign in Champaign County Illinois as shown in Figures 2-1 and 2-2: The building

.,was,,supported by 30 metal-shell, cast-in-place concrete piles with minimum lengths of 40.5 feet.

A 6.5-foot deep by 1-foot wide concrete foundation, which was laid on concrete pile caps, supported the walls. The building housed a TRIGA pool-type reactor designed and constructed by General Atomic Division of General Dynamics Corporation. The reactor operated under NRC License R-I 15.

The University discontinued operations, of its Advanced TRIGA nuclear research reactor at the NRL in 1998. Prior to shutdown of the. reactor and the removal of the reactor fuel elements in 2004, the University decided to decommission and dismantle the NRL and terminate the NRC license. In 2007, the NRC approved the. NRL DP which required the, complete removal of the reactor,, systems, and demolition of the facility.

In 2011, the University selected a team led by LVI Environmental Services, Inc. (LVI), a D&D contractor, to safely implement the DP. Additional members of this team included Enercon Services, Inc. and AECOM Technical Services; Inc. Beginning in October 2011, the team began removing the legacy waste from the NRL. The reactor bridge and control *rod drive were 3

The reactor-core assembly (core; Lazy Susan, reflector; grid.plates; stand, etA.), as removed in.

January 2012 with the subsequent- removal of activated portions of the bioshield. Auxiliary systems within the NRL were removed and the NRL was decontaminated where necessary to support *afilul radiological releae survey.- The contractor performed the release survey and following a confirmatory survey by the NRC, the building was demolished except for the cast-in-place concrete pilings and the concrete sumps.

_ V"'I In July 2012, the FSS was conducted per the NRC-approved FSS Plan. A Class I survey unit consisted of the building .footprint (i.e., the exposed soil excavation area). A Class 2 survey unit.

consisted of the immediate. area surrounding the excavation area.

2.3 Decommissioning Activities Decommissioning entailed numerous tasks -involving remediation, dismantlement; and.-

demolition of various systems,:.structures, and components with a"constantfocus on safety and limiting radiation dose to the on-site staff. This section details the result of these tasks. The final project collective Total Effective Dose Equivalent (TEDE) to personnel was 2.57 person-rem.

The DP estimated the collective project dose to be 8.5 person-rem and there were no. OSHA recordable injuries or lost work time incidents.

-SERVICES, Nuclear Reactor Final Status LabReport Survey D&D 2.3.1 Miscellaneous Non-contaminated Items.

Following site mobilization, the non-reactor related equipment and materials located throughout the facility .were collected, surveyed- with Geiger Muller (GM) detectors,. and released-from the-facility for reuse or for disposal as clean trash. All released items were surveyed for removable and fixed contamination, including removable tritium. There were no indications of any activity above detectable levels with minimum detectable concentrations (MDC) equal t6 no -greater than 50 percent of the Regulatory Guide 1.86 release criteria as described in the DP. These materials included office and shop equipment, old radiation detectors that were no longer in serVice, and miscellaneous materials used or stored in the NRL.

2.3.2 Glove Box One of the. first,jlarge., radioactive items removed, during the initial decommissioning activities.

was a glove box located on the reactor room lower level. The glove box was characterized for waste disposal and determined to contain uranium isotopes. The glove box was disconnected from its ventilation stack and duct work and packaged without disassembly into a 20-foot sealand container. The ventilation ductwork was additionally wrapped in polyvinyl and added to the container alofig with herculite fill material. The container was shipped offsite for processing and disposal as low level radioactive waste (LLRW).

2.3.3 Reactor Components More .than 90 percent of the reactor components were removed prior to bioshield demolition.

Pool water was Jleft i6 the reactor tank to provide shielding. The reactor bridge was removed and-all of the components packaged for disposal as LLRW.

The "LazySusan," which contained several, curies of Co-60 in its activatedstellite bearings, was separated from the reactor assembly to reduce worker dose*exposure during reactor assembly-dismantlement.,,It was placed in a shielded container and stored in the southeast comer of the reactor room floor until a shipping cask was available. Prior to removal, an ALARA review was performed to ensure dose to radiation workers and the public was kept as low as possible and within regulatory limits. Concrete blocks from the bioshield were placed around the container for shielding.. Dose rate .surveys of the container and surrounding area were performed after placement and the area was posted in accordance with the radiation control plan.

1151 ".University of Illinois I' .. Nuclear Reactor Lab D&D SERVIS Final Status Survey Report Due to the elevated dose rate of the Lazy Susan, a: Type A shipping cask was-required to" transport .the article to the waste disposal site. When the shipping cask arrived- at the NRL, the Lazy Susan container-was removed from the facility..and placed in the.cask and shipped to EnergySolutions' Containerized Waste Facility in Clive, Utah.

Following removal of the Lazy Susan, the reactor tank water was pumped to a holding tank, the core support was unbolted from the tank bottom, the beam ports were cut from the reflector, and

.the reactor assembly was removed. The assembly contained three lifting eyes and was pulled from. the pool with the NRL's overhead crane. The reflector contained poured lead inside an aluminum shell. This reflector was shipped for offsite processing to remove the lead-which was disposed as mixed waste. The remaining portions of the aluminum assembly were repackaged.

offsite and disposed as LLRW.

The TEDE for-the removal of the reactor assembly (.including removal of the Lazy Susan) as well as the loading and shipping of the same was approximately 1. 1 person-rem.

2.3.4 Reactor Tank Water Initially'the" water in the reactor tank was partially drained and the water was managed according to the existing Universityprocedures. :-This allowed better access to reactor components while still providing* sufficient shielding to keep dose rates ALARA. After the reactor components were removed, the tank was completely drained. When the water level approached the bottom, the water was agitated to suspend radioactive deposits on the bottom of the reactor tank. The tank water was filtered to remove the suspended particulate matter. After passing through a particulate filter and ion exchange resin, the tank water was added to a 1,000-gallon hold up tank and sampled according to current University procedures allowing the filtered water to be discharged to the sanitary sewer system. Dose rates were carefully monitored as the tank was drained, .and never exceededlimits set in the Radiation Work Permit (RWP).

2.3.5 'Reactor Tank The upper portions of the reactor tank were removed during diamond wire cutting activities described in the following section. -As the concrete blocks from the top 12 feet of the bioshield were removed, the top portion of thealuminum tank sections was also removed: The tank pieces 7

'"I~ .Nuclear Reactor Lab D&D SERVICES .. .- Final Status Survey Report, were. not anchored or attached to -the concrete in any way and were easily separated from the..

blocks. The tank pieces were surveyed and some surface contaminration was identified. These pieces of the tanks were managed as LLRW.'

The lower part of the reactor tank was removed during the inside-out demolition of the-lower

- section of the bioshield described below. The removal of the lower part of the reactor tank-was performed- remotely in a negative air containment that was .constructed over the bioshield.

Aluminum pieces were removed from the bioshield interior and. packaged for disposal as LLRW. .

2.3.6 Bioshield and Bulk Shielding Tank Segmentation .

LVI used diamond wire cutting, performed by Cutting Edge, Inc., to segment the upper level of the concrete bioshield and the Bulk Shielding Tank (BST). The purpose of the removal action was to allow more direct access tO the reactor and internals and to remove the BST walls to support the demolitionof the lower activated regions of the bioshield using a Brokk demolition tool. The Bioshield Wiresaw Cutting Work Plan (MCP-OPS-04) provided instructions for cutting the: concrete into manageable sections. However, prior to making the initial cuts in the top of the bioshield, the top surface of the bioshield was decontaminated. Contamination-levels of approximately. 10,000 dpm beta/gamma were reduced to non-detectable levels. The decontamination waste was collected into vacuums and added to the LLRW waste stream..

The bioshield concrete was cut into 3-ton maximum blocks, using air-cooled diamond core drills and water-cooled track saw and diamond wire saws. With these specialized cutting tools, .dust and debris were strictly controlled. A recycling system utilizing a "Slurry Fox" filter press was used to filter the water before* circulating back to the cutting tools. The resulting slurry from the filtered cutting water was drummed and shipped offsite as LLRW for processing and disposal..

. Concrete blocks. removed from the bioshield and BST were surveyed with GM detectors to demonstrate that they contained no detectable levels of contamination or-activation prior to their release as clean-waste. Additionally, concrete samples were collected from 14 different blocks - -

using a hammer-drill. These samples were biased toward the most likely activated areas such as the blocks in proximity to, the reactor core. Samples were examined by an independent laboratory for tritium, iron-55, nickel-63, and gamma-emitting radionuclides. The analysis of 8

.. .W "Nuclear Reactor Lab D&D SERVICES* Final Status SurveyReport each concrete block sample indicated that contaminants of concern were below detectable levels.

Concrete blocks were shipped to a local landfill as non-radiological "clean" waste.,

2.3.7 Bioshield Demolition and Beam Tube

'Removals The Site Characterization Report (Scientech 2005b)-

estimated that the reactor bioshield 'was activated to a depth of about 3 feet into the concrete from the-tank wall and to a -height of about 4 feet from the reactor core centerline. With the use of a remote contr6l Brokk 330 and demolition hammer attachment; this "area of activation" was removed working from the inside out. This demolition work was performed under negative air with air filtered through high-efficiencyparticulate air (HEPA) filters. concrete rubble and rebar was packaged in "super

_sacks" and ultimately disposed of as LLRW.

The characterization assessment of the area of activation was relatively accurate6- However, neutron scatter along the length of the beam tubes had activated a few inches of the concrete surrounding the beam tubes. As such, four of the six beam tubes were completely removed from the bioshield using the Brokk and the surrounding concrete decontaminated. The remaining two beam tubes were left for removal during the final demolition of the bioshield.

Following the removal of the activated, concrete, the interior cavity of the bioshield was surveyed and sampled. If a survey point demonstrated potential residual activity, the'location was further decontaminated using hand demolition tools. Concrete samples indicated that the bioshield met the release criteria provided in the DP.

2.3.8 Forced Circulation System The primary pump and heat exchanger from the reactor tank water circulation system were located in the Mechanical Equipment Room. These items were disconnected and removed from the Mechanical Equipment Room intact (no cutting or sawing). All system components were surveyed for free release. No contamination was detected on approximately 75% of the systems and they were free released. The heat exchanger. and primary pump were determined to be.

. . . .University

. of Illinois fi Nuclear Reactor Lab D&D SERWCES. Final Status Survey Report internally contaminated above release limits and managed as LLRW. The pump motor, which was separate from the pump, was free of internal contamination.

There were two nitrogen- 16 (N- 16) decay tanks located in a vault under the Mechanical Equipment Room. One tank had a 3,000-gallon-capacity and the other tank had a 1,500-gallon capacity. These tanks were emptied to the extent possible and the.water was added to the hold-up tank- for filtering and testing' according to. University procedures before -ultimately being released. into the sewer. Once the water was .removed from each -of the tanks, they were segmented into manageable-sections. Each piece was surveyed with GM detectors with more-than 75%/*of the sections. shown to be free of detectable contamination and free released. The contaminated. sections were packaged and shipped offsite for processing and disposal as LLRW.

2.3.9 Water Retention System The water retention system consisted of three floor drains, a trench.drain; the emergency shower drain, the utility sink drain, associated piping embedded in the concrete floor of the reactor room, and the 500-gallon storage tank located in a small vault under the western side of the reactor room floor north of the Radioactive Materials Storage Cage.ý-. The water retention system remained intact through the majority, of the D&D project so that it could be utilized to contain spills and/or process water (such as water needed for, concrete cutting or coring). The 500-gallon storage tank-was removed from the pit when wet decommissioning tasks were complete. It was surveyed and released as clean waste. --

One of the three floor drains was identified during confirmatory surveys as having measureable contamination.'. The drain and an impacted section of pipe and conduit were removed during the -

demolition of the concrete floor. About -4 feet of pipe and 4 feet of conduit were disposed as&:

LLRW.

2.3.10 Dry Fuel Storage Pits There were six dry fuel storage pits located in the floor of the truck loading bay. These pits were 1 foot in diameter, 8 feet deep, and lined with 3/8-inch steel with a 1/2-inch bottom plate. Each pit had a 1-foot thick concrete end plug with a 14-inch diameter steel cap. Each pit contained an aluminum storage rack. Surveys with GM detectors showed no activation or contamination 10

University of Illinois Nuclear Reactor Lab D&D SERVES Final Status Survey Report above detectable levels within the tubes or the caps. The tubes were removed as clean waste along with concrete floor during final demolition.

2.3.11 Building Exhaust System The building exhaust system consisted of filter housing on the storage level, a charcoal filter bed, exhaust ducts, and the roof stack and blower. The exhaust system was operated during decommissioning operations until after the removal of the activated interior concrete of the bioshield. Once the system was shut down, the filter media (charcoal and fiber filters) were removed and disposed as LLRW. The entire exhaust system was then surveyed and no contamination was identified above detectable levels. The exhaust system components were disposed of as clean waste.

2.3.12 Interference Removal After the final removal of activated concrete from the interior of the bioshield, the remaining interferences within the NRL were removed. These materials consisted of piping, conduit, wall hangers' and other miscellaneous items. These materials were surveyed and determined to be free of detectable contamination.

2.3.13 Building Clearance Survey and Sampling The goal of the building clearance surveys was to document that the building materials included in the demolition debris meet free-release criteria established in the Section 2.1.5 of the DP. The methods described in MARSSIM were used to provide a statistical basis for the design of the surveys. Surveys included interior floor and wall surfaces in the reactor room, control room, offices, materials storage areas, mechanical rooms, etc. (including doors). Surveys also included overheads such as ceilings, roofing supports, the bridge crane, and the roof of the mezzanine office. Exterior surveys included wall surfaces, doors, and roof materials.

Samples from the-concrete floors and the interior surface of the bioshield were also collected and analyzed for the activation products of concern provided in Table 2-4 for the DP. A total of 33 samples (including one duplicate: sample) were collected and analyzed by Teledyne Brown Engineering, Inc.

• University of Illinois

,Nuclear ReactorLab D&D Final Status Survey Report After the completion of the building clearance surveys and sampling, Oak Ridge Institute for Science and Education (ORISE) performed a confirmatory survey for the NRC. ORISE collected five split concrete samples from the reactor bioshield; collected two additional biased bioshield samples, and collected a sample fromthe pipe tunnel below the reactor bioshield. A collective analysis of all surveys and sample results indicated that the building could be demolished in accordance with the DP.'

2.3.14 Building Demolition After the completion of the building clearance survey and approval from the NRC, the. building, including the remainder of the bioshield, was demolished. Demolition began with the systematic removal of the exterior concrete block walls. This approach was required because the hollow blocks, were discovered to contain vermiculite, an asbestos-containing material. Theblocks and the vermiculite were disposed of at a local landfill as asbestos-containing material.

Following removal of these blocks, the remaining structure was demolished in two weeks utilizing a large track hoe with various demolition attachments. Demolition debris and rubble was segregated and disposed of as clean waste. Metal and roofing materials were separated from concrete rubble resulting in approximately two truckloads of each material. About 8000 cubic feet of concrete waste was generated from the.

floor and bioshield demolition. All trucks containing demolition debris were surveyed using a gamma exposure rate meter prior to leaving the site; none measured higher than background. Concrete footings and pylons remained in place following demolition of the NRL structure consistent with DP. The survey of these items is described as part of the FSS in Section 4.0.

3.0 FINAL

STATUS SURVEY METHODOLOGY The' FSS provided data and information to demonstrate that the NRL facility and site complies-,

with the NRC annual dose 'limit -c iteria of 25-mrem/yr TEDE, by meeting the radiological criteria listed in'the DP as approved by the-NRC for use for the termination of NRC`

License R-115.

The FSS was designed in accordance with -the ,.NRC-approved FSS' Plan, CS-RS-PN-003

• (EnergySolutions, 201.1),. in order, to, demonstrate that the NRL site complies with..the radiological release criteria stated. in Section 3.1. The FSS Plan described the process for survey preparation, survey design, data collection, data evaluation, and documentation of survey-results.

The FSS included gross gamma scans and collection of soil samples analyzed via gamma spectroscopy for the radionuclides of interest and analyzed for HTD radionuclides.

3.1 Release Criteria For the UI FSS, the NRC License Termination Screening Levels for surface soils listed in NUREG 1757, Volume I, Appendix B Table B.2 were approved as the derived concentration.-

guideline -levels (DCGLw). The NRC-approved screening criteria for UIUC NRL radionuclides of concern are listed in Table 3-1. Compliance with the volumetric contamination screening criteria was -demonstrated with a combination of gamma walkover --surveys and -volumetric material sampling and analysis. - -

"lefU.- University of Illinois Nuclear Reactor Lab D&D SERVICE. Final Status Survey Report The release criteria for surface contamination on remaining buildingg materials, such as concrete or steel footingsand foundation, are provided in Table 3-2. -These release criteria are from the:

NRC's Regulatory Guide 1.86.

Table 3-2: Release Criteria for Surface Contamination.

Average" 1 Maximum"2 Removable Net beta-gammia activity 5,000 15,000 1,000 in dpm/100 cm 2 Notes: n' Averaged over not more than 1 square meter

'2 Applicable to an area of not more than 100 square centimeters The average and maximum activity values apply to the total beta-gamma activity from the gamma-emitting radionuclides in Table 3-2 and, carbon-14. The detector efficiency. for-carbon-14 was used to conservatively estimate the total activity. The removable contamination limit applies to theihard-to-detect isotopes as well as those detectable with direct measurements, 3.2 Classification and Sample Size Area classification in accordance with MARSSIM protocols ensures that the number of

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

Areas that may contain residual radioactivity from licensed activities are considered impacted areas. Based on the levels of residual radioactivity .present, impacted areas are further divided into Class 1, Class 2, or Class 3 designations. Class I areas have the greatest potential for residual activity while Class 3 areas have the least potential for residual contamination. Each-classification will typically be bounded by areas classified one step lower to provide a buffer zone around the higher class. Exceptions occur when an area is surrounded by a significant 14

L-:.Nuclear SERWCE5 university of Illinois Reactor Lab D&D Final Status Survey Report physical barrier that would make transport of residual activity unlikely from one area to the adjacent area. In such cases, each area will be classified solely on its own-merit using the most reliable information available.....

3.2.1 Sample and Location Identification Measurement and sampling locations were determined using the methods provided in MARSSIM.

For the Class I survey unit, the random start location for the sample location-grid was biased so that it would fall within the footprint of the N-16 tank vault so that samples could be collected from under the concrete floor before building demolition. This was necessary as the vault was not to be removed during building demolition because of safety concerns. The number of primary samples, twenty-eight'(28), was determined in the FSS Plan using MARSSIM protocols and site characterization data. Also as described in the FSS Plan, because HTD .isotopes are not detectable with a walkover survey, additional secondary sample locations within the MARSSIM-derived sample grid were added to the sampling scheiiiem*. There were twenty-eight (28) additional sample locations.-

For the Class 2 survey unit, sample locations were evenly spaced'around the rectangular

• perimeter.Class 1 survey unit. The number of samples was determined in the FSS Plan.

An off-site laboratory facility, Teledyne Brown Engineering Laboratory in Knoxville,-TN, was used for gamma spectroscopy and HTD analyses of all FSS Soil samples.

-3.3 Types and Methods of Surveys Survey measurements Were performed by personnel trained and qualified in accordance With the' FSS Plan.

... . .University of Illinois LV. . Nuclear Reactor Lab D&D SER. ES. Final Status Survey Report 3.4 Survey Instrumentation Handheld portable instruments were selected that provided an adequate response to radionuclides of concern and capable of having a MDC less than the applicable release criteria for the survey.

The MDC was calculated using formulae contained in MARSSIM and shown in Section 5.2.3.

The MARSSIM contains the most. current guidance on recommended methods of calculating survey instrument. MDC. The background rate and detector efficiency used in the MDCare..

averages calculated from the daily operational check of each instrument.

3.4.1 Instrument Models The instruments selected for this survey are described .in the following sections. Technical description data sheets for each instrument and detector used are provided in Appendix A.

3.4.1.1 Ludlum Model 2221 with 44-9 "Pancake" GM Detector The Model 2221 with 44-9 detector was used for beta/gamma static and scan measurements on the concrete footings. The active area of the-detector is 15 cm2 .

3.4.1.2 Ludlum Model 2221 with Model 44-10 2x2 Nal Detector The Model 2221 with 44-10 was used for gamma radiation walkover .surveys and direct measurements across the Class 1 and Class 2 FSS areas. The 2x2 Nal detector has a sensitivity of approximately 900 cpm per microRoentgen per hour (PtR/hr) for Cs- 137.

3.4.1.3 Ludlum Model 19 MicroR The Model 19 was-used for gamma exposure rate surveys. The generally accepted MDC of this instrument is equivalent to. the background readings.

3.4.2 Instrument Calibration All field instrumentation was calibrated by MJW Technical Services located in Olean, NY. The survey instruments were calibrated prior, to initiation of the FSS. ENERCON maintains original instrument calibration data at the calibration lab and provided copies to the on-site project file.

Appendix B provides the calibration records for the instruments used.

University of Illinois Nuclear Reactor Lab D&D SERVCE5. Final Status Survey Report 3.4.3 Pre-Operational Checks Background readings for counting-instruments were conducted daily during instrument use. Any instrument that used a battery had a daily battery check performed before instrument operation.

An 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 response rate for rate meters and 1-minute static count for scalers) and a count of a known check source. (observed response rate. for rate meters .and 1-.minute static count for scalers) with the detector in contact with the source in its holder to provide a consistent source to detector distance. If at any time an instrument exceeded its calibration due date or fell outside of the +/-10 percent of the established initial source response, the instrument was replaced or recalibrated, and a new initial source check was performed.- This information was recorded on a Daily Source Check Log form. Appendix C provides the results of the source check measurements made for instruments used during the FSS.

3.4.4 Instrument Efficiency The efficiency of the detection capabilities for each GM instrument was'calculated using the following formula:

E W,(C-Cb)

Instrument Efficiency (El) S Where:

Cs= Measured source count in cpm Cb = Measured background count in cpm S = 2 pi source activity value in dpm Total instrument Efficiency (Et) Et Ei E* .

Where:

Ei = Instrument efficiency E, = Surface efficiency (0.25 for beta emitters < 400 keV f3max) 17

5*jJ -~University of Illinois WI Nuclear Reactor Lab D&D SERCES.. ..... . Final Status Survey Report The total instrument efficiency (Et) is a product of the instrument efficiency (Ei) and the surface efficiency. (Es) and is used to convert the raw instrument counts into the standardized unit of dpm. The surface efficiency utilized follows the recommendations in ISO-7503-1, which makes recommendations for default surface efficiencies. A surface efficiency of 0.25 is recommended for beta emitters with maximum energies less than 400 keV (NUREG 1507); therefore, the surface efficiency used for the FSS was 0.25 based on a beta energy maximum 318 keV for Co-60.

3.4.5 Minimum Detectable Concentration The instrument and detector combination selected for the wall and floor scans had a MDC well below the.release criteria specified in Section 3.1 as shown in Table 3-3. The MDC is the concentration Iof radioactivity that, an- instrument- can be expected to detect.. at- a,95 percent.

confidence level. For instruments performing direct and/or scan measurements, the MDC goal was 10 to 50% of the applicable release criteria. The MDC goals were met for the FSS instruments and information used to calculate the MDC for instrumentation used during the FSS were documented on the radiation survey form.

For static (direct) surface measurements, with conventional detectors, the MDC was calculated using the formula:

2 +Ts /Tbr MDC.(dpm/lO00cm ) =[3+3.29-(A/XTsX1 Variables:

Rb = Background count rate (cpm)

Tb = Background count time (min)

T =SampleCount Time (min) - .

E, = Total Instrument Efficiency (MARSSIM Section 6.6.1)

The MDCsan for beta-gamma measurements was calculated by determining the Minimum Detectable Count Rate (MDCR). The MDCR was determined by first determining the minimum detectable net source, counts using Formula 6-8 in the MARSSIM as below...

5.0 CONCLUSION

S The results for the soil samples support an unrestricted release of the NRC license. In the Class 1 excavation area survey unit, only two of the 56 soil samples had detectable Cs-137 concentrations with a maximum result of 0.1 pCi/g; approximately I% of its release criteria. In the Class 2 perimeter survey unit, the maximum result for 28 soil samples collected was 0.25 pCi/g of Cs-137 (i.e., 2% of the release criteria) out of only 4 samples that had detectable Cs-137.

The Cs-137 results can be! attributable to fall-but from historical atmospheric testing of nuclear weapons. No other radionuclides of concern were detected in the FSS samples and all gamma walkover count rates were at background levels.

Based on the results of the NRL FSS, the conditions in 10CFR20.1402, Radiologicalcriteriafor unrestricieduse, have been met with the absolute maximum dose to. an average member of the

.public calculated (by compwison of the residual concentration of material to the release criteria) to be less that 0.5 mrem per year or 2% of the release criteria.
