Page 2 of20, Rev. PURPOSE Final status surveys of site soils at the Plum Brook Rector Facility (PBRF) decommissioning will include scans and static measurements, using Sodium Iodide (NaI) detectors, and soil sampling. Scanning and static measurement techniques do not measure individual radionuclide activity concentrations; they measure the gamma decay activity of the soil matrix. Scanning and static measurements provide for screening a survey unit's surface as appropriate for that survey unit's Final Status Survey classification. Soil sampling allows for the comparison of individual radionuclide concentrations against derived concentration guideline levels (DCGLs) and demonstrates that survey unit's compliance with the release criterion. Application of these methods requires knowledge of the radionuclides present and their activity ratios. As this document supposes the reviewer is versed and qualified in the discipline(s) required to perform and assess Final Status Surveys, this document will make use of common FSS terminology, principles and lexicon, without copious footnotes or references to supporting documents. DCGLs for individual radionuclides were developed previously and are reported in the Final Status Survey Plan for the Plum Brook Reactor Facility (FSSP) [NASA 2006]. Included in that document was an evaluation of residual contamination radionuclide profiles in site soils. This document builds on the existing FSSP in two ways: The final products of this document are as follows: to ascertain an appropriate soil DCGLsur (Surrogate DCGL) for areas which can be defined by;

• similar activity deposition histories
• comparable nuclide distributions after assessing characterization data and, to delineate where on the PBRF grounds these DCGLsurs apply. The referenced coding to designate where samples were taken, and which survey packages directed and documented them, is provided in Appendix A of this document.

Maps showing the locations of soil samples are depicted in Appendix B. Soil sample results from both on-site and off-site analyses are shown in Appendix C. Appendix D presents the DCGL sur calculations. Appendix E contains the map(s) which graphically delineate where the DCGLsurs apply. BACKGROUND 2.1 Initial Sampling Efforts Under MWH, Characterization Survey Packages were developed and executed in order to collect soil samples from around the Plum Brook Reactor Facility PBRF-TBD-09-00Page 3 of20, Rev. * (PBRF). Survey package areas designated with the A21 00, A2200, and A2400 codes accounted for all sampling inside the PBRF perimeter fence. Survey packages designated A2300 collected samples along the centerline of Pen to lite Ditch from the WEMS outfall to the v-notch weir on the south side of Pentolite Road at the confluence of Pen to lite Ditch and Plum Brook. The A2300 packages were expanded to include open land areas away from the ditch, particularly to the south of Pen to lite Ditch. Geo-probe samples (for taking samples at depth) were collected in order to aid in bounding the depth of contamination. Survey packages designated as A2500 encompassed soil sampling outside the perimeter fence not including the Pentolite Ditch. On January 30, 2004, eight samples were sent to off-site laboratories for IOCFR61 analyses. Four samples were from the Emergency Retention Basin (A2I00) and four from what is now Spill Area #4. Results from the IOCFR61 analyses were eventually incorporated into the FSSP [NASA 2006]. On August 26, 2004, four additional samples were sent off site. These samples originated from Areas of Cone em AOC-IB (one sample), AGC l-C (two samples), and AOC-2 (one sample). Dose assessments and DCGL calculations for site soils are described in detail in the FSSP from which excerpts appear in the next few paragraphs. The results of those DCGL calculations are reprinted as Table 2-1. The Site-Specific DCGL

• values are the surface soil activity levels, in pico-curies per gram, that will be used during FSS to determine compliance with the 25 mrem/yr unrestricted use criterion.

Values in Table 2-1 were calculated by RESRAD using parameters specified in Tables B-1 through B-8 of the FSSP. Table 2-1 DCGLs for Surface Soils Radionuclide Site-Specific DCGL (pCi/g) Fe-55 71,000 Fe-59 14,000 Co-60 3.8 Ni-63 5,400 Sr-90 5.4 Cs-137 14.7 Eu-152 8.8 Eu-I54 8.2 Per NUREG-1757, the Nuclear Regulatory Commission (NRC) staff considers radionuclides and exposure pathways that contribute no greater than 10% of the

• 25 mrem/yr dose criteria to be insignificant contributors

[USNRC 2003]. As the 10% limit for insignificant contributors is an aggregate limitation, the sum of the dose contributions for all radionuclides and pathways considered insignificant PBRF-Page 4 of20, Rev.

• will be no greater than 10% of the dose criteria of 25 mrem/yr per 10CFR20, Subpart E [USNRC 1997b]. For PBRF soils, the dose from all radionuclides other than Co-60, Sr-90, and 137 totaled 0.5 mrem/yr. Because this dose is only 2% of the 25 mrem/yr.limit, all radionuclides, other than Co-60, Sr-90, and Cs-13 7, were eliminated from further consideration.

To ensure the 25 mrem/yr criterion is met any open land survey unit, where the mean of the FSS results indicates that the dose may be greater than 24.5 mrem/yr, will be reviewed for compliance with the unrestricted use limit. Table 2-2 follows from the removal of insignificant radionuclides. Table DCGLs for Surface and Sub-Surface* Radionuclide Site-Specific DCGL (pCilg) Co-60 3.8 Sr-90 5.4 Cs-137 14.7 *As conservatism in the public interest, NASA determined to use the surface soil DCGLs for both surface and sub-surface soils.

• 2.2 Subsequent Sampling Efforts MOTA Corporation was issued a contract to continue decommissioning work after MWH. Under the direction of the NASA Project RSO, MOTA and other contract personnel initiated the Survey Request program to follow up on soil samples taken from around the site; SR43 for the Pentolite Ditch, SR3 plus SRI6 for the six spill sites within the perimeter fence, the former burn site on Snake Road (SRI), and the waste treatment facility on Taylor Road which was demolished in 2005 (SR2l). 2.3 General The DCGL w is the DCGL for average concentrations over a wide area, used with statistical tests. At the PBRF, soil samples were collected and analyzed over large soil surfaces on the site. One basis for collecting and analyzing these samples is to assess for minor disparities in the distribution ofthe site specific radionuclides.

These disparities are used to refine the DCGL sur value for radiologically contiguous areas at the PBRF. The surrogate radio nuclide can be detected with high certainty using equipment readily available on-site. In the case of the PBRF, Cs-137 can be readily detected by existing equipment and Cs-137 will be used as the surrogate nuclide in most, but not all, soil survey unit packages.

• There are defined spill locations on the PBRF where Co-60 dominates the mix of radionuclides and is the appropriate surrogate nuclide. Co-60 can be readily PBRF-TBD-09-00 1 Page 5 of20, Rev. 0
• detected by existing equipment and Co-60 will be used as the surrogate nuclide for these survey unit packages.

For these survey unit packages, a Co-60 DCGLsur value will be calculated. PBRF radiation detection equipment utilized for scanning and static measurements can be calibrated to Cs-137 or Co-60 "windows". These windows discriminate for the photon energies of the appropriate surrogate nuclides. This discrimination optimizes the detectors response for the surrogate photon energies in the sampling environment. PBRF utilizes a qualified on-site laboratory for performing gamma-spectrum analysis of soil samples (see section 4.2 of this document). A contractor supplied, conveyorized, soil sorting system will also be employed to segregate soils complying with the unrestricted use criterion, from soils which require disposal as waste. DCGLsur values as determined in this TBD are assigned to areas exhibiting similar radiological distributions and characteristics. The expectation is that there will be more than one DCGLs ur value for the site soils. The primary determinants for these radionuclide distributions are the historical operational conditions and uses around the PBRF, known radioactive spills in the area, soil movement and cleanup during D&D activities, ditch cleanout and restoration, and other activities which could deposit definable radionuclide distributions into a specific area.

• Review of the facility design, operational history, and available survey and sample results (MWH 2004), indicate that radionuclide distributions in PBRF soils have some variability across the PBRF. The PBRF has been shut down for approximately 36 years. This represents more than six half-lives for Co-60, and little more than one half-life for Sr-90 and Cs-137. The expectation will be for Cs-137 to dominate the radionuclide distributions, but as described earlier for spill areas, etc., this expectation does not hold true over the entire site. The following is a description of what is meant by a radionuclide profile (distribution).

The NRC Staffhas stated that "A unique radionuclide profile must be developed for each of the major types of materials expected to remain onsite after remediation" [USNRC 2003].1 To that end, this technical basis document provides a summary of and the rationale for use of unique DCGL sur values for soils around the PBRF site. Radionuclide profiles were developed for each of the three sets of samples which were sent for off-site analyses (see Appendix D). Section 2.1 of this document described and defined how the list of significant radionuclides has been sorted to consist of three; Co-60, Sr-90, and Cs-137. In this document, the DCGLsur values for specific soil areas are developed in Appendix D and listed in Table 5-2. These DCGLsurs and their respective nuclide distributions correspond to an annual dose of 25 mremlyr to a future occupant.

• The purpose of the PBRF decommissioning project is to release the site for unrestricted use in compliance with the NRC's annual dose limit of25 mremlyr TEDE to an average member of the critical group. Additionally, the residual radioactivity should be reduced to levels that are as low as reasonably achievable (ALARA) [USNRC 1997b]. The NRC dose limits apply to residual radioactivity that is distinguishable from background.

The DCGL values established within the FSSP will not be increased without prior NRC approval. PBRF-TBD-09-00Page 7 of20, Rev. *

• 4.0 MATERIAL DESCRIPTIONS 4.1 Description of Samples All soil samples referenced in this document are collected in accordance with site procedures (e.g. split spoon, geo-probe, or hand augers). Site procedures also direct and control the methods used for moisture removal, dimensional reduction, removal of extraneous materials, homogenizing the samples, and packaging the samples for gamma-spectroscopy.

Site procedures also direct the methods and documentation used for the custody control of samples from the point of collection to long term storage or disposal. 4.2 Analyses of Samples The PBRF has an on-site counting lab capable of performing gamma spectroscopy using high-purity germanium detectors. Soil samples are evaluated for gamma-emitting radioisotopes: typically Cs-137 and Co-60. On March 8, 2005, the lab implemented RP-60, Revision 0 which is the PBRF Radiological Laboratory Quality Assurance/Quality Control Program.

• To supplement the on-site lab, two off-site labs were used to perform lOCFR61 analyses prior to and after the implementation of RP-60, "PBRF Radiological Laboratory Quality Assurance/Quality Control Program".

Both Severn Trent Laboratories, Inc., Earth City, Missouri and Eberline Services Lionville Laboratory, Inc., Oak Ridge, Tennessee were used to perform supplemental analyses of samples. These labs were capable of drying samples and performing the requisite digestions, separations, wet chemistry, and neutralization in order to perform alpha spectroscopy, liquid scintillation, and gamma spectroscopy. All soil samples collected on this project were analyzed by gamma spectroscopy in the PBRF Counting Laboratory. Twelve soil samples were sent off site for further gamma-spec analyses to include alpha-emitting radionuclides, hard to detects (H-3, C-14, Fe-55), and pure beta-emitters (Sr-90, Ni-63).

• 5.0 ASSESSMENT 5.1 Radionuclide Mixtures for FSS The radionuc1ides listed in Tables 2-1 and 2-2 were selected after a detailed evaluation of characterization data, collected in 2004, which included soil samples taken from the both Emergency Retention Basin (ERB) and what is now Spill Site 4. ERB, Spill Site 4, and additional soil samples from AOC-1B, AOC-IC, and AOC-2 were used to calculate DCGLs ur values in Attachment D. Current soil sample data, listed in Appendix C, are used for comparison to the DCGLsur values for FSS. Table 5-1 shows the radionuclides remaining after eliminating the insignificant radionuclides from Table 2-1. Table 5-1 DCGLs for both Surface and Sub-Surface Soils Site-Specific DCGL Radionuclide (pCi/g) Co-60 Sr-90 Cs-137 A reasonable and conservative assumption would be that all soil samples will contain a mixture of the three radio nuclides shown in Table 5-1. 5.2 Equations Hard-to-detect radionuclides (low energy beta emitters such as H-3, C-14, Ni-63, 1-129 and non-beta emitters for soils, HTDs) were eliminated as being a portion of the large number of insignificant contributors.

Sr-90 remained as the sole HTD needing a surrogate relationship to a radionuclide that is detectable. Cs-137 and Co-60 are readily detectable surrogates. They will be the DCGLsurs as appropriate to direct soil segregation prior to utilizing the contractor supplied, conveyorized, soil sorting system, and when performing final status surveys of soil for each discrete survey area, and the survey unites) within that area. The DCGL sur accounts for the surrogate being used to assess Sr-90 contribution to the unrestricted use criterion. For site soils, the final DCGL for FSS design and implementation is an activity per unit of mass DCGL that represents the 25 mrem/yr unrestricted use criterion. PBRF-TBD-09-00 1 Page 10 of20, Rev. 0

• As described in Section 2.3 the PBRF is using detectors and conveyorized, soil sorting systems which are calibrated with photon energy specific windows. 137 or Co-60 can therefore be the surrogate(s) for all significant contributor radionuc1ides.

The equations to be used were derived from NUREG-1505 [USNRC 1997a] and are presented below. 5.2.1 Surrogate DCGL Equation The surrogate DCGL is computed based on the distribution ratio between the hard-to-detect radionuclides and the easy-to-detect radionuclides. The surrogate DCGL is calculated using the following equation: Where: DCGL sur = Surrogate radionuclide DCGL DCGLt = DCGL for the radionuclide to be used as the surrogate for the other radionuclides DCGL 2 , DCGL 3 , *.. DCGL n , = DCGL for each radionuclide to be

• represented by the surrogate R2, R3, Rn =Ratio of concentration (or nuclide activity fraction) of each radionuclide to the surrogate radionuc1ide 5.2.2 Unity Rule Equation When more than one radionuclide is present in a soil sample, the unity rule is used as the first test to evaluate compliance with radiological criteria for license termination.

A surrogate DCGL, if applicable, would be used in the unity rule calculation. The unity rule equation is: Where: C n = concentration of radionuclide "n" DCGL n= DCGL of radionuclide

n. If the unity rule test fails (Le., the calculated sum of fractions is > 1), the evaluation of the individual radionuc1ide concentrations against their respective DCGL values is performed.

• 5.3 Compilation of Site Soil Data Analyses 5.3.1 Overview The PBRF has been shut down for approximately 36 years. This represents more than six half-lives for Co-60, and little more than one half-life for 90 and Cs-137. The expectation will be for Cs-137 to dominate the radionuclide distributions, but as described earlier for spill areas, this expectation does not hold true over the entire site. Ratios 3.0 indicate an area where Co-60 is more limiting as compared to it's DCGL and is the more appropriate surrogate nuclide. Significant and reproducible variations in the expected ratio provide a timely marker to cognizant personnel that further evaluation of the survey areas radionuclide distribution may be required.

5.3.2 Evaluation of Soil Sample Data Several sampling campaigns have taken place under different contractors as described in Section 2.0. The data gathered from these campaigns supports four calculated DCGLsur values (see Appendix D) that will be used during FSS. The four calculated DCGLsur values, in pCi/g, are;

• 13.34 from the Pentolite Ditch 11.55 from Spill Site 4 (representing areas inside the security fence exclusive of the ERB and the PPH spill area) [DCGLsurCs137] 10.31 from the ERB [DCGLs urCs 137] 3.28 from the PPH Spill Site 1 (representing Spill Sites 1,2 and 3) [DCGLsur Co60] The values in Table 5-2 present the DCGLsur values to be used in the FSS design packages.

Appendix C collates the laboratory results and analytical data used in the equations and the DCGLs ur calculations found in Appendix D. All data used in calculating the DCGL sur values in Appendix D are decay-corrected to 8/1/07 to reflect the radionuclide activity mix within the same time reference as the last data collected. The data collated in Appendix C was not decay-corrected; any ratios and activity fractions are current as of the dates those samples were analyzed. In a significant number of data sets, enough time has elapsed since the samples were analyzed, that the activity values of those samples have now decayed to <MDA. Assessing data for DCGL sur development and compliance with the unrestricted use criterion within these parameters, adds a significant factor of conservatism to the analysis. Nuclides whose fractions are eliminated as per Section 3.5 of the PBRF FSSP and Section 7.3 of Attachment A of the PBRF FSSP are not presented in Table Following Table 5-2, each area or group of areas is analyzed as to why listed DCGLs ur is PBRF-TBD-09-00 1 Page 12 of20, Rev. 0

A ratio could not be calculated for all samples due to either radionuclide being <MDA. 717 samples had both radionuclides

>MDA. There were 1280 samples where positive Cs-137 existed with Co-60 <MDA. The highest value ofCs-137 in this case was 431 pCi/g at Spill Site 3, while most of the values were just above MDA. There were only 57 instances of positive Co-60 with 137 <MDA. In most of those 57 instances, the Co-60 value was just above the MDA of 0.08-0.09 pCi/g. There were 320 samples where both radionuclides were <MDA. 5.3.3 Emergency Retention Basin (Surrogate nuclide: Cs-137) Four soil samples were sent for off-site analysis. The samples revealed the presence of all three of the Table 5-1 radionuclides and other selected radionuclides. The surrogate DCGL value of 10.31 was calculated from the results of the off-site, full spectrum analysis. 5.3.4 Pentolite Ditch and Areas ofConcem (Surrogate nuclide: Cs-137) Two samples from the Pentolite Ditch and one sample each from AOC-IB and AOC-2 were used to calculate the surrogate DCGL value of 13.34. Sr-90 is represented in the surrogate calculation by MDA or actual sample activity whichever is greater. Evaluation ofthe Cs-137:Co-60 ratios from Appendix C data determines that, without exception, single digit Cs:Co ratios were calculated from samples where both radionuclides were only 5-10 times their respective MDA values and a factor of 10 or more under their respective DCGLs. For sample results greater than the proposed surrogate DCGL value, the Cs:Co ratios invariably are greater than 10: 1 and generally much greater than 10:1. This has the effect of having the lower ratios associated with noise and the larger ratios associated with meaningful activity.

• Interviews with retirees indicate that the Pentolite Ditch was cleaned out periodically with an excavator, and the spoils were placed in piles on the south side of the ditch, and on the east and west banks of the Plum Brook south of the weir. The spoils piles were then graded off with a bulldozer, filling in low spots and leveling the grounds south of the Pentolite Ditch, and to the east and west ofthe banks ofthe Plum Brook south of the weir.

• It is not unreasonable to expect that all the Areas of Concern will have radioactive materials in similar concentrations and ratios to those encountered in the Pentolite Ditch, since the Areas of Concern exist because of these ditch spoils. Therefore, the Pentolite Ditch and the Areas of Concern use the surrogate DCGL value of 13.34. 5.3.5 Survey Units 1 through 10 (Surrogate nuclide: Cs-137) There were 1784 samples taken inside the PBRF perimeter fence, not including those taken specifically for known or suspected spill areas. Of those, fewer than 17% actually had quantifiable Cs:Co ratios and approximately 80% of those ratios were based on values close to the MDAs. The remainder of the samples were Cs-137 consistent with atmospheric bomb fallout. Four samples from the Spill Site 4 were sent for off-site analysis.

The samples revealed the presence of all three of the Table 5-1 radionuclides and other de-selected radionuclides. The surrogate DCGL value of 11.55 was calculated from results of the off-site analysis. Sr-90 is represented in the surrogate calculation by MDA or actual sample activity whichever is greater. The Spill Site 4 DCGLsur is evaluated to be the most limiting based on mechanisms for activity deposition and operating history for these areas inside the PBRF security fence. The DCGLsurof 11.55 will be used for Survey Units 1 through 10Of 103 samples collected in Survey Unit 1, two are greater than 10% of unity, two are greater than 50% of unity, and none are greater than unity. Co-60 appears in 21 samples and there are 19 samples with quantifiable Cs:Co ratios. Cs-137 represents almost 85% of the total activity of all samples. With the exception of the two samples greater than 50% of unity, the remaining Cs-137 samples are indicative of what one would expect to see from fallout due to nuclear bomb tests. Of 184 samples collected in Survey Unit 2, 28 are greater than 10% of unity, 20 are greater than 50% of unity, and 13 are greater than unity. 60 appears in 63 samples and there are 56 samples with quantifiable Cs:Co ratios. Cs-137 represents almost 88% of the total activity of all samples. Most of the remaining Cs-13 7 samples are indicative of what one would expect to see from fallout due to nuclear bomb tests. Of20l samples collected in Survey Unit 3, 25 are greater than 10% of unity, 17 are greater than 50% of unity, and 13 are greater than unity. 60 appears in 52 samples and there are 48 samples with quantifiable Cs:Co ratios. Cs-137 represents more than 95% of the total activity of all samples. Most of the remaining Cs-137 samples are indicative of what one would expect to see from fallout due to nuclear bomb tests.

• Of 134 samples collected in Survey Unit 4, three are greater than 10% of unity, none are greater than 50% of unity, and by default, none are greater PBRF-TBD-09-00 1 Page 15 of20, Rev. 0
• than unity. Co-60 appears in 23 samples and there are 21 samples with quantifiable Cs:Co ratios. Cs-137 represents more than 95% of the total activity of all samples. Of 134 samples 130 contain Cs-13 7 levels consistent with what one would expect to see from fallout due to nuclear bomb tests. Two samples had Cs-137 activities less than 10% of unity, but were clearly above what would be expected from fallout. Of 139 samples collected in Survey Unit 5, two are greater than 10% of unity, none are greater than 50% of unity, and by default, none are greater than unity. Co-60 appears in 13 samples and there are 12 samples with quantifiable Cs:Co ratios. Cs-137 represents more than 82% of the total activity of all samples. Of 139 samples 135 contain Cs-137 levels consistent with what one would expect to see from fallout due to nuclear bomb tests. Three samples had Cs-137 activities less than 10% of unity, but were clearly above what would be expected from fallout.
• Of 397 samples collected in Survey Unit 6, seven are greater than 10% of unity, two are greater than 50% of unity, and none are greater than unity. Co-60 appears in 76 samples and there are 67 samples with quantifiable Cs:Co ratios. Cs-137 represents more than 79% of the total activity of all samples. Only six samples appear to contain Cs-137 activity levels above what one would expect from fallout. This means that even though there were 67 quantifiable Cs:Co ratios, only about six are meaningful, because the others were ratios of values just above the respective MDAs for the two radionuclides.

Of 164 samples collected in Survey Unit 7, six are greater than 10% of unity, one is greater than 50% of unity, and none are greater than unity. Co-60 appears in 25 samples and there are 20 samples with quantifiable Cs:Co ratios. Cs-137 represents more than 82% of the total activity of all samples. Only three samples appear to contain Cs-137 activity levels above what one would expect from fallout. One sample was greater than 10% of unity from its Co-60 activity alone. It turns out that the four samples, which were greater than 10% of unity, are the only ones that have physical significance with respect to their Cs:Co ratios because all the others were ratios of values just above the individual radionuclide MDAs. Of 230 samples collected in Survey Unit 8, three are greater than 10% of unity, one is greater than 50% of unity, and that same one is greater than unity. Co-60 appears in 35 samples and those same 35 samples have quantifiable Cs:Co ratios. Cs-137 represents more than 93% of the total activity of all samples. Only two samples appear to contain Cs-137 activity levels above what one would expect from fallout. One sample

• was greater than 10% of unity from its Co-60 activity alone. As it turns out, the three samples which were greater than 10% of unity are the only ones that have physical significance with respect to their Cs:Co ratios PBRF-TBD-09-00 1 Page 16 of20, Rev. 0
• because all the others were ratios of values just above the individual radionuclide MDAs. Of 145 samples collected in Survey Unit 9, none were greater than 10% of unity. Co-60 appears in 14 samples of which 13 samples have quantifiable Cs:Co ratios. Cs-137 represents more than 80% of the total activity of all samples. All the samples were at or slightly above the respective MDAs for Cs-137 and Co-60. Of 87 samples collected in Survey Unit 10, none were greater than 10% of unity. Co-60 appears in 12 samples of which 10 samples have quantifiable Cs:Co ratios. Cs-137 represents more than 93% of the total activity of all samples. All the samples were at or slightly above the respective MDAs for Cs-137 and Co-60. 5.3.6 Spill Sites 1,2, and 3 (Surrogate nuclide: Co-60)
• Appendix D uses data taken from Spill Site 1 to calculate soil DCGLs for the single DCGLsurCo60.

This represents samples acquired under SR-3 and analyzed on-site after implementing RP-60, "PBRF Radiological Laboratory Quality Assurance/Quality Control Program." These samples were not subjected to full-spectrum analysis, the sample results were consistent with site norms for gamma emitting nuclides with the exception of the typical Cs-Co ratio. For this soil area (and two others as reflected in Table 5-2 of this TBD) Co-60 is the more appropriate surrogate DCGL. For nuclide distribution, four representative samples were deselected of the radionuclides that contribute no more than 10% to the 25 mrem/yr dose. The resultant fractions were normalized for Co-60 and Cs-137 to baseline the representative fractions for the DCGL sur cooo. Review of samples analyzed off-site for full-spectrum analysis indicated the most conservative (i.e. greatest) fractional contributor from Sr-90 for any sample would be 8.54%. This value was used to determine a normalized distribution including Co-60, Cs-137 and Sr-90 for the DCGLsurCo60 of 3.28. 5.3.6.1 Spill Site 1 Eleven surface soil samples were collected from the Spill Site 1 area. Seven of the samples produced Cs:Co ratios less than one which indicates that Co-60 is the predominant species in the mix. A representative selection of these samples will be assessed for full spectrum analysis. Any necessary adjustments to the DCGL sur Co60 will be made prior to performing final status survey of Spill Sites 1,2 or 3. PBRF-TBD-09-00 1 Page 17 of20, Rev. 0 5.3.6.2 Spill Site 2 (Surrogate nuclide: Co-60)

• Only six surface soil samples were collected at Spill Site 2. All Cs-137 appear to be consistent with fallout from atomic bomb testing. Three samples contained Co-60 above the detection limit. 5.3.6.3 Spill Site 3 (Surrogate nuclide: Co-60) Of23 samples collected from Spill Site 3, four indicate Cs-137 activity levels greater than that which would be expected from atomic bomb fallout testing while two others indicate Co-60 activity well in excess ofthe Cs-137 activity at the same location.

5.3.7 Spill Site 4 (Surrogate nuclide: Cs-137)

• For this area four soil samples were sent for off-site analysis.

The samples revealed the presence of all three of the Table 5-1 radionuclides and other de-selected radionuclides. Sr-90 and Co-60 are represented in the surrogate calculation by MDA or actual sample activity whichever is greater. The surrogate DCGL value of 11.55 was calculated from results of the off-site analysis. The surrogate DCGL has an artificially higher 60 distribution. This is due to a single sample of the four sample set with a specific activity for Cs-138 lower than the other three samples by one order of magnitude. As Co-60 is the most limiting single nuclide it has been assessed to keep this artificial distribution as a conservative adjustment to the surrogate DCGL of 11.55. 5.3.8 Spill Sites 5 and 6 5.3.8.1 Spill Site 5 (Surrogate nuclide: Cs-137) Nine of 11 samples collected from Spill Site 5 indicate no detectable Co-60 and Cs-137 consistent with atomic bomb fallout. Two samples indicate detectable levels of both radionuclides dominated by the Cs-13 7 component. The unity calculations for the two are 0.42 and 0.09. These indicators plus an operational history otherwise consistent with Survey Units 1 through 10 infer the appropriate surrogate DCGL value to be 11.55. 5.3.8.2 Spill Site 6 (Surrogate nuclide: Cs-137) All 10 samples from Spill Site 6 indicate <MDA Co-60. Nine of 10 samples have Cs-137 activities consistent with atomic bomb fallout values. These indicators plus an operational history otherwise consistent with Survey Units 1 through 10 infer the appropriate surrogate DCGL value to be 11.55. 5.3.9 Outside Perimeter Fence (Surrogate nuclide: Cs-137)

• The area directly east of the WEMS (Building 1192) has detectable activity in the soil with two samples (52 and 57) above unity and five PBRF-TBD-09-00 1 Page 18 of20, Rev. 0
• others (13, 52, 54, 55, and 56) greater than 50% of unity. This area clearly needs some remediation.

The remainder of the survey unit outside the perimeter fence displays Cs-137 values consistent with fallout and Cs:Co ratios calculated using Co-60 values near the MDA. All sub-surface samples are less than 10% of unity. As indicated by retiree interviews, the WEMS was cleaned out periodically. In addition, the north end of the WEMS was excavated in order to bury drainage piping entering the WEMS as part of the PBRF site drainage modifications. Spoils from both the excavation and periodic algae removal operations were deposited east of the WEMS. In attempting to choose an appropriate surrogate DCGL value, the following logic was used. The ERB received water from the WEMS when liquid effluent release alarms sounded in the Control Room. The WEMS gates would close and the water routed to the ERB until the alarm condition cleared. Since the material east of the WEMS originated in the WEMS, the surrogate DCGL value assigned is 10.31, consistent with the ERB surrogate DCGL value. 5.3.10 Radioactive Material Storage Area (Surrogate nuclide: Cs-137)

• This area was used as a storage area for soil sacks during the remediation of AOC-IA. There is no indication that radioactive materials were stored there in the past. All samples collected during the execution of this survey package indicated Cs-13 7 levels consistent with those due to fallout from nuclear bomb tests and all Co-60 values were near its MDA. The most appropriate surrogate DCGL value to be assigned would be 13.34, consistent with the Pentolite Ditch. 5.3.11 Burn Site (Surrogate nuclide: Cs-137) Twelve samples were taken and none of them revealed Co-60. All Cs-13 7 values are consistent with bomb test fallout. The most appropriate surrogate DCGL value to be assigned would be 13.34, consistent with the Pentolite Ditch's high Cs-137 and small Co-60 contributors.

5.3.12 Waste Treatment Facility (Surrogate nuclide: Cs-137) Similar to the Burn Site, no Co-60 was detected in 17 samples. Very low Cs-137 values detennined fonn gamma spectroscopic analysis. The most appropriate surrogate DCGL value to be assigned would be 13.34, consistent with the Pentolite Ditch.

6.0 CONCLUSION

S

• From section one, the final products of this document are as follows:

PBRF-TBD-09-00 1 Page 19 of20, Rev. 0 to ascertain an appropriate soil DCGLsur (Surrogate DCGL) for areas which can be defined by; similar activity deposition histories comparable nuclide distributions after assessing characterization to delineate where on the PBRF grounds these DCGLsurs apply. Appendix D calculates the DCGLsur value. Table 5-2 delineates where the new DCGL sur values apply and sections 5.3.3 through 5.3.14 describe why the DCGLs ur is acceptable. There are three Cs-137 surrogate values (DCGLs ur cSl37) associated with site soils. In pCi/g, the DCGLsurcs137S are 10.31 from the ERB, 11.55 from Spill Site 4, and 13.34 from the Pentolite Ditch. There are a few areas where Co-60 predominates the nuclide mix or is a significant contributor <<3.0 Cs:Co ratio). In these areas a Co-60 surrogate value DCGL (DCGL sur C060) is used. In pCi/g, the DCGLs ur C060 is 3.28 from Spill Site 1. Choosing the DCGL sur value for an area was based on evaluation of the Appendix C data, basic statistics, and good engineering judgment. There are discrete areas of the Plum Brook inside the Plum Brook Facility security fence which will be remediated. These portions of Plum Brook are designated as being contiguous with the Pentolite Ditch for characterization, remediation, and evaluation for compliance with the release criterion. Cs-137 and Co-60 constitute the prevalent radioactive species throughout the site. Their activity ratios are a useful marker for evaluating the consistency of soil characterization as remediation progresses. As a result of decay half-life, the Cs-137: Co-60 ratio for any discrete survey area increases over time (the Cs-137 half life is effectively five times as long as the Co-60 halflife). As Cs-137 represents the majority of the activity for the vast majority of survey areas, the DCGLs ur Csl37 value will increase over time. An administrative ceiling will be implemented for determining that adequate remediation has been accomplished using the surrogate radionuclides. This ceiling is being implemented to accomplish two goals; provide remediation contractors with a ceiling for segregation and remediation which assures any given survey unit's compliance with the release criterion during Final Status Survey, and ease the physical precision with which survey areas undergoing remediation must be segregated from each other incident to boundary control in the presence heavy equipment movement, this provides an acceptable level of remediation boundary control, while maintaining cost-effectiveness A comprehensive map which depicts where the appropriate administrative ceiling should be applied is included as Appendix E. PBRF-TBD-09-00 1 Page 20 of 20, Rev. 0

• The administrative ceiling is determined to be 10.31 pCi/g (rounded down to 10.0 pCi/g) for those survey areas listed in table 5-2 as using Cs-137 as the surrogate radionuclide.

The administrative ceiling is determined to be 3.28 pCi/g (rounded down to 3.0 pCi/g) for those survey areas listed in table 5-2 as using Co-60 as the surrogate radionuclide. Other conclusions reflected in Table 5-2 are: The DCGLs ur for the Pentolite Ditch (including the contiguous portions of Plum Brook) and all six Areas ofConcem are identical. All were dominated by Cs-l37 at or above 90% of the radio nuclide mix. The Cs-137:Co-60 activity ratio is in the double digits: averaging approximately 80: 1. Of 12 samples sent for off-site analyses, none showed alpha emitters greater than a few tenths of a percent of the total activity. Pure beta-emitters, although representing 10-20% of activity in some cases, were dominated by H-3, C-14, and Ni-63: all characterized by emission of very low energy betas with average energies of6 keY for H-3, 52 keY for C-14, and 20 keY for Ni-63). For these reasons, those radionuclides were eliminated from the DCGL calculations as they were deemed to be insignificant contributors.

• PBRF-TBD-09-001, Appendix C
• Page -z.. of e, , Rev 0 Appendix B was a presentation of maps indicating the locations where most soil samples were collected.

Data from the soil samples collected and analyzed for this document are presented in Attachment C. The NOTES: I. Samples sent for off-site analyses are highlighted in boldface type as " OFF -SITE". 2. AOC-I was split into three separate regions due to its size (see maps in Appendix B): a. AOC-IB extends from west of the WEMS (1192) to E23200. b. AOC-IC extends from E23200 to E23600. c. AOC-IA extends from E23600 to E2400. Samples used for DCGL development in Appendix D are presented as discrete sample sets. Sample sets used for assessing Cs:Co ratios are presented as full sample sets with the specific number of samples used for ratio assessment documented in the lower left comer of each set.

• Page 2 of 2 , Rev 0 Appendix D uses data taken from Spill Site 4, the ERB, Pentolite Ditch, AOC-IB, and AOC-2 to calculate soil DCGLs for the three DCGL sur Cs137S. These represent those samples sent for off-site, spectrum analysis. Addendum 1 shows the actual results from the off-site analyses, Addendum 2 takes the Addendum 1 data and removes radionuclides that contribute no more than 10% to the 25 mrem/yr dose as they are deemed to be insignificant.

It also decay-corrects the remaining data to August 1,2007: the end of characterization data acquisition for DCGL refinement. Addendum 3 takes the Addendum 2 data and calculates the site soil DCGLs. In summary, the distribution of radionuclides in the soil at the PBRF are consistent within the three calculated DCGLs ur cs137 areas identified in Section 5.3.2 with only minor, non-compliance limiting, variations within each area.

• Appendix D uses data taken from Spill Site I to calculate soil DCGLs for the single DCGLsur Co60. This represents samples acquired under SR-3 and analyzed on-site after implementing 60, "PBRF Radiological Laboratory Quality Assurance/Quality Control Program." These samples were not subjected to full-spectrum analysis, the sample results were consistent with site norms for gamma emitting nuclides with the exception of the typical Cs-Co ratio. For this soil area (and two others as reflected in Table 5-2 of this TBD) Co-60 is the more appropriate surrogate DCGL. For nuclide distribution, four representative samples were deselected of the radionuclides that contribute no more than 10% to the 25 mrem/yr dose. The resultant fractions were normalized for Co-60 and Cs-137 to baseline the representative fractions for the DCGL sur C060. Review of samples analyzed off-site for spectrum analysis indicated the most conservative (i.e. greatest) fractional contributor from Sr-90 for any sample would be 8.54%. This value was used to determine a normalized distribution including 60, Cs-137 and Sr-90 for the DCGLsurCo60.

These samples will be assessed for full spectrum analysis. Any necessary adjustments to the DCGL sur Co60 will be made prior to performing final status survey of Spill Sites I, 2 or 3. TBO-o9-o01, Appendix 0, Surface Soil Sample Analytical Results Addendum 1 Page 1 of 3,
