Docket No. 70-3073 License No. SNM-1999
Dear Mr. Widmayer:
This letter requests NRC approval of the attached Sector 10 Rubble Survey Work Plan and Technical Memorandum. These documents are similar in nature to our June 18, 2003 submittals for Sector 8 which were approved by your letter dated August 15, 2003. The contamination in Sector 10 is primarily SNM, as addressed in the modified Work Plan and Technical Memorandum. However, the procedures and modeling utilize similar concepts which were previously applied toward successfully surveying the Sector 8 rubble materials.
We will use the knowledge and lessons learned from the Sector 8 work to ensure that this work is also implemented in a manner that meets all criteria.
We would like to begin work on this project as soon as possible. As the procedures and technical justification are similar in nature to that submitted for the Sector 8 work, we would appreciate your assistance in expediting the review and approval process as much as possible.
Copies of the Work Plan and Technical Memorandum are attached for your review. If you have any questions or comments, please contact Jeff Lux at (918) 223-2522 or call me at (918) 223-2526.

DRI(A1F1 Kerr-McGee Citshim: Site Scctol 10 itublle Scegiegatiunand Survcy Work Phnil 1.(I PURPOSE The purpose of this work pklai is to provide instruct ions for segregating and surveying small rubble and debris fe.g.. building materials, primarily concrete and brick chunks) found in tile Sedinieuit Pile Area of Sector 10 of tile Kerr-McGee (KM) Gushing site-This debris has to be removed to complpete decommissioning of the soil and structures in Sector 10. This material is more soil-like than equipment-like and the exposure scenario is similar to tile soil exposure scenario. Con11SCqUelntly tIle volumltric criterion is morc alpprolpriate tlan the surfacc contamination criterion. Normal swiipC. scan, amid integrated survey methods are ineffective and impractical on much of this debris due to size andlor irregular shape. The objective is to demonstrate that the material mects the release cmitcria specified in tile Site Decommissionimig Pllanl (SDP) and NRC License SNM-1999.
2.0 HISTORY Tue Sediment Pile Area of Sector 10 consists of approximately 250 square ineters of property bounded by thc I-laul lRoad Corridor oll the northwest, west, and south and theRMA-10 on the northeast and cast. Tle area forumis a linger-oflf oflMA-10.
During t(ie JELLWaR project thie Process Buildings were rdismanlded. Thle initial ient was to remove the concretc that exceeded the criteria for disposal as Low Level Radioactive Waste (LLRW) and (hien remove the non-impacted concrete as industrial waste. However; the concrete became brittle with age and the initial phases of the removal caused large sections of time concrete to shatter into rubble. T7he large pieces that wcre identifiable as impacted were stacked for disposal as LLRW. Thle remaining large pieces have been surveyed using conventional swipe, scan, and integrated survey mnetliods. Approximately 200 cubic yards of smiall, irregular shaped rubble remains to be surveyed by an alternate method.
3.0 IKllELY CONTlAMINANTS The concrete rubble and debris remaining is not identifiable as being from a particular building surface. Conscqunctly, both uranium anmd thorium contamination is possible. The uranium contamination could be in tile lori) of natural or enriched uraniun. The impacted soil in the area of tile Process Buildings showed an average enrichiment of 3.5%.
Portions of the buildings were used for refinery operations prior to the nuclear processing years. Thus, TENORM (radiun pipe scale) is also a possible contamiination source. While not a licensed radioactive material, tile TENORM will also have to be remediated to satisfy thle Consent Order with the State of Oklahoma and the exposure rate criteria of the SDP.
The thoritiui and radiumil arc easily (letectable with ganima instrumentatioum. By modifying the procedure used for tile Sector 8 rubble as described in Section 6, the uranium call also be reliably detected as sh5owI n [iCe attached Technical Memo.

Subject:
Na Scan Survey of Concrete Rubble Containing SNM' in Sector 10 of the Xerr-McGee Cushing Site Revision: 0 ENDORSEMENT This document contains the results of research and technical analysis which have been reviewed an approved for publication by the Technical Director, NEXTEP Environmental, Inc.
iX27Ao3 Harry J. Newman, CHP, Technical Director Date I
INTRODUCTION The work plan for the Kerr-McGee Cushing Site includes the survey and release of concrete rubble from buildings that were demolished2. Technical Memorandum (TM) 03-14 discussed this situation for natural Uranium, natural Thorium and their mixtures under the assumption of equilibrium. The measurement results of sector 10 show that enriched uranium exists in this area and there is no evidence show radiological equilibrium.
In this TM, the MCNP3 code is used to simulate the radiological characteristics and geometry of concrete block and to determine the detection capabilities of the instrumentation that is proposed for the release surveys.
Accordingly, the objectives of this Technical Memo are:
- 1) Estimate the detection limit LD for direct measurement and the a priori Minimum Detectable Count Rate (MDCR) for scan surveys based upon the predicted background for several detector configurations.
SNM stands for Special Nuclear Material.

- 2) Simulate the count rate (in units of cpm) that result from different cases of contamination in order to show whether contamination at the release limit can be observed.
- 3) Recommend a measurement method for the concrete.
2 ANALYSIS OF ON-SITE MEASUREMENT RESULTS Table 1 shows on-site measurement results from concrete in Sector 10 at the Kerr-McGee Cushing site.
From these results, the following conclusions can be made; these conclusions will be applied to the MCNP model construction.
- 1) The enrichment of U-235 varied from 1.04% to 8.8%.
- 2) The average enrichment of U-235 is 3.54%.
- 3) There is no evidence to show that natural uranium (i.e. in equilibrium) is present.
The assumption of natural uranium in equilibrium in TM 03-144 is invalid for these samples.
- 4) To verify the reliability of measurement results, the activity percentage of U-234, U-235, and U-238 vs. the enrichment of U-235 was plotted as shown in Figure 1.
Figure 1 was compared with Figure 2-2 from the Health Physics Manual of Good Practices for Uranium Facilities5 (see Appendix E, attached). The comparison visually and empirically shows good agreement and implies that the measurement results are reliable.
The regression trend lines are given for U-234 and U-238. These trend lines will be used to estimate the activity percentage for U-234 and U-238.
These percentages will be further used to calculate the activity for each nuclide at various enrichments.

- 5) The average ratio of U-238 to Ra-226 is 15.9. This result indicates that the radiological equilibrium has not been established for U-238.
- 6) The average activity density of 0.8 pCi/g for Ra-226 shows that the activity of Ra-226 in these samples is at approximately background levels.
- 7) The average total Uranium for the sample data set is about 90 pCi/g (82.4 pCi/g in Table 1). According to Equation 1 of TM 03-146, for the Uranium only case, this amount of Uranium is about 3 FMPC.
- 8) The average amount of total Thorium for the sample data set is about 5pCi/g (4.58pCi/g in Table 1).
This average amount of Thorium is equal to a contamination level of approximately 0.5 FMPC (no background subtraction) for Thorium only and is elevated above background. Table 1 also shows that Thorium was not present in some samples (B101E80S55-035-D, BIOIE85S50-020, BlOlE85S50-010, B101E90S45-005, BlOlE8OS55-035). Therefore, in this TM, Thorium-232 will not be included in the MCNP model. This consideration will make the conclusion of this TM more conservative since Thorium is easier to detect than uranium. The presence of even fractional FMPCs of thorium above background can significantly improve detection sensitivity.
3 LAYOUT OF MATERIAL (GENERAL GEOMETRY)
It is assumed that the concrete debris has been broken into small chunk-like pieces and that larger pieces will have been removed7. These small chunk-like pieces will be placed together to form a "wind row," which is a long row 1 foot high and 4 feet wide. There will be air gaps within the "wind row" in between the chunks of concrete. In the MCNP model the "wind row" is modeled as a standard 1 meter x 1 meter by 1 foot whole concrete block. Also, for modeling simplification, the physical existence of the air gap within the "wind row" is accounted for by a decrease in the density of the concrete block.
In the MCNP model for this TM, it is assumed that 15% of the concrete block volume will be air, so the density of this concrete block is decreased from 2.6g/cm3 to 2.2g/cm 3.
Figure 2 illustrates the basic geometry for the MCNP model used in this TM. The contaminated layer as depicted can vary in location and be on the top or bottom surface to provide a range of detector sensitivities.

Figure 2 General Geometry of MCNP Model The detector to be used for surveying the concrete is a 3"xl/2" Nal detector. There are two detector configurations and usage modes which are generally adopted on-site:
shielded with measurements made at a height of 6" above the surface, and unshielded with measurments made at a height of 24" above the surface. To study more possible detector configurations, both shielded and unshielded cases as well as the additional measurement heights of 0" (detector placed directly onto surface) and 2" above the surface will be also considered in this TM.
4 REPORTED BACKGROUND COUNTING RATE According to TM 03-148 and TM 03-119, 16 m2 is a large enough surface area for the performance of background simulation modeling. This area is much larger than the effective detectable area for each detector configuration.
The MCNP model used for background simulation was very similar to the general model shown in Figure 1, except the dimensions of the concrete block were changed to 4m x 4m x I foot.
Table 2 lists the background activity densities assumed for the concrete block.
These activities were uniformly distributed throughout the concrete block in the background models.

The total number of photons used to determine background the count rate was 55,794,600 y/minute (929,950 y/second). These results were calculated by running the MicroShield code. The output for this result is listed in Attachment A-1, and was obtained by summing the photon emission rate from all available energy bins for each radionuclide.
As in TM 03-14, "an additional count rate of 2,500cpm was added to the (simulated) background to account for other environmental sources of gamma radiation at the site" Table 3 shows the calculated background counting rate for the detector configuration.

DETECTION LIMITATION After the background counting rates are obtained, several important detection limits can be derived according to these background counting rates.
5-1 LD - DETECTION LIMIT FOR DIRECT MEASUREMENT The theory of Detection Limit can be found in MARSSIM" ' and will be omitted in this section. The equation for calculation of the detection limit is as follows.
Equation 1 LD =3+ 4.654B Where B = Background Counts The LD demonstrates the detection capability for direct measurement for a certain type of detector. LD is an a priori estimate of the detection capability of a measurement system and is reported in units of net counts above background. If the measurement count is lower than this number, the source that generated this lower count cannot be distinguished from background and therefore cannot be detected. On the other hand, if the measured counts are higher than this number, there is radioactivity above background.

5-2 MNIMUM DETECTABLE COuNT RATE(MDCR)
The formula for calculating the minimum detectable net count rate (MDCR) of a scanning instrument is given by equation 2.
MDCR is used for scan survey so in its calculation, it considers the factor called surveyor efficiency (p in equation 2).
The observation interval i is determined by dividing 1 meter length of concrete block by the survey speed. In this TM, two scan speeds will be assumed, 30cm/seond and 15 cm/second.
Equation 2 MDCR =
dF,6 4-4P Where:
MDCR = minimum detectable net count rate (ct/min) d'

According to the discussion above, the LD for different counting times and MDCR for different scan speeds are calculated according to the background counting rates listed in Table 3. All the results are listed in Table 4.
From Table 4, it can be seen that the limits of shielded cases are very close, no matter the detector height. The same can be said for the unshielded cases. Based on this fact, Table 4 can be simplified to Table 5. In Table 5, the limits are categorized by shielded and unshielded. For each category, the limit with the largest value from the three heights under each category is reported.

CONTAMINATION In TM 03-14, to determine the total amount of radioactivity, it was assumed that contamination at the level of either 1 FMPC or 3 FMPC was uniformly distributed throughout the entire concrete block. In this TM, this assumption is still valid and it will be denoted as Assumed Total Activity (ATA). The ATA for different enrichments will be different.
In TMO3-14, all the ATA was assigned to a lcm-contamination layer on the bottom surface. This assumption is also valid in this TM.
However, in this TM, the contamination layer will be assigned to the top surface of the concrete block (least conservative case), bottom surface of concrete block (most conservative case) and randomly assigned within the concrete block (most realistic case).
In this TM, total-U is the only contaminant of concern. The enrichment of U-235 will be the key factor affecting the activity distribution. Four enrichments were selected for modeling and they are listed in Table 5 along with the reason for selection.
If the enrichment of U-235 is known, the activity percentage of each nuclide in the uranium family can be determined. Once the activity for each nuclide is known, the ATA can be calculated by MICROSHIELD code. The results of these calculations are also listed in Table 6.

- The activity percentage for each nuclide at enrichment 3.54 is calculated from the equations in Figure 1. The activity percentage for each nuclide at enrichment of 8.08 and 1.03 are measurements results from Table 1.

7-3 CONTAMINATION RANDOMLY ASSIGNED TO THE CONCRETE BLOCK.
The discussion above assumed the contamination layer was either at the top or bottom of the concrete. Neither of these two cases are realistic. From TM 03-14, it is known that the concrete debris will be broken into small chunks and any chunks that are larger than 16" x 16" will be removed. Any remaining chunks will be dumped into a "wind row."
Under this arrangement, the contamination layer will be randomly distributed within the concrete "wind row."
To construct the random distribution model, the concrete block was divided into 27 cells, which is illustrated in Figure 5(a). Number 1 to 6 are assigned to each surface of each cell as shown in Figure 5(b).
MS EXCEL was then used to randomly select contamination surfaces for each of 27 cells according to Equation 4.
Equation 4 Random Surface Number = INT(RANDO*6+1)
Then the ATA was assigned to the 27 randomly selected 1 cm thick surfaces.

For the random case, use of the average results from several model runs will give a better estimate of the mean than if only a single model result is used. The ideal case is to run 30 random models or more and then take the average of these 30 simulation results.
However, this is not practicable since there are 4 detector configurations (2" shielded, 2" unshielded, 6" shielded and 24" unshielded) and 4 enrichment arrangements (0.72%,
1.04%, 3.54%, and 8.8%), their combinations would require a total of 480 separate model runs.

- 1) One random model (baseline) was run for each case. This gave a simulation result for each enrichment case. This random model was called random model-00.

- 2) Because 3.54% enrichment was the average concrete enrichment, it was selected as the basis for running the 30 random models.
- 3) For contamination with 3.54% enrichment, 30 random models were run for each of the 4 detector configurations. These models were called random models 01-30 for each configuration.
- 4) The average result of these 30 random models were then compared with the result from baseline random model-00. The comparison result, i.e., average-to-00 ratio, was then applied to all the other 00 (baseline) results so that corrected results could be obtained for each enrichment.
These corrected results were then reported as simulation results.
Table 9 shows the simulation results for the baseline cases. Table 9(a) gives the results for 1 FMPC contamination level and Table 9(b) gives the results for 3 FMPC level.

- All results cpm Table 10 shows that the 2" unshielded configuration is the best configuration within the six selections. The most difficult case is for 8.8 enrichment. For this case, the predicted counting rate is 495 cpm.
This value is larger than the MDCR of 407 with a 15cm/second scan speed. This means if a 15cm/second scan speed is adopted, every enrichment combination can be detected.
The 6" shielded configuration is presently used on site.
The results show that thel 5cm/second scan speed is adequate for detecting 1 FMPC at all enrichments.
An evaluation was performed to evaluate the random partitioning of the contamination.
It was found that the values in the Table 10 may be somewhat underestimated due to the following two facts.
One is from the random model itself. For 30 random models, each model has 27 cells.
Each cell is assigned a surface number. So, 810 surfaces are selected in total. Figure 6 shows the frequency plot for surface selection. (The arrangement of each surface are listed in Appendix B) Figure 6 shows that the appearances of each surface follows the Binomial distribution. If the probability of each surface appears is equal, the probability for each surface is 1/6=0.17. According to the properties of the binomial distribution, the expected number of appearances should be the total number of samples, (810 in this case) times the associated probability, and should be 135. The standard deviation (1 a) should be the square root of 135 x (1-0.17) and equal to 10. From appendix B, the number of appearances for each surface, 1 to 6 are: 125, 156, 132, 136, 121 and 140. This result shows that each surface appears evenly from a statistic viewpoint (i.e. within expected statistical deviation).

Figure 6 also shows that surface 2 appears more than the other surfaces. Because surface 2 is at the bottom of each cell, the results from these 30 samples potentially underestimate the counting rate to a small degree.

Figure 6 Appearance Frequency for the Contaminated Surface The second factor is that Thorium was not considered in these models. From Table 1, it can be seen that, although some samples show that there is no Thorium in those samples, the average of total Thorium is about 5 pCi/g. This will contribute 0.5 FMPC to the total contamination. So the counting rate will be larger than those listed in Table 9. Thorium is much easier to detect than Uranium as has been documented in TM 03-14.
Table I1 shows the summary of analysis of 30 random samples for each detector configuration. The detailed data and statistic summary are listed in Appendix C.
Appendix C lists the MCNP simulation results from the 30 sample runs in the left hand columns. The simulated cpm is the modeled count rate at an enrichment of 3.54% and at 1.0 FMPC total uranium above background. In the center of each data summary there is a statistical analysis. The mean count rate can also be found in Table 10(a). At the bottom of each summary page are rows labeled "Limit,"
"# > limit," and "% > limit."
The "Limit" row is equivalent to the highest LD or MDCR for shielded or unshielded detectors, as applicable from Table 4.
The '# > limit" is equal to the number of measurements above the LD or MDCR, as applicable, for the count time or scan rate of interest. The '"°/0 > limit" is equal to the percentage of measurements above the LD or MDCR, as applicable, for the count time or scan rate of interest.

Table I I shows that for the average enrichment, the 2" unshielded detector configuration has more advantages than other detector configurations. First, for direct measurements, 1 minute is sufficient to detect contamination at 1 FMPC in all cases in the '"vind row."
Second, if a 15 cm/second scan speed is adopted, the possibility of detecting the contamination by scan survey is larger than 900%.
Table I I also shows that the 6" shielded configuration is a good choice. 2-minute direct measurements can guarantee finding the contamination at I FMPC in the "wind row."
Use of al5cm/second scan speed will allow for an 87% success rate in locating contamination at 1 FMPC during scans.
Table 1 1 suggests that the 2" shielded and 24" unshielded configurations may not be used for scan surveys.
Appendix D contains a listing of all files used to generate this TM. Copies of all files will be maintained by NEXTEP as proprietary material for review as required.
8 CONCLUSIONS I) If uranium contamination is located on the top surface of a concrete layer, it can be detected using a 3" x 0.5" NaI detector (all configurations).
- 2) Uranium contamination located on the bottom surface of concrete cannot be detected with confidence.
- 3) For the general case, if the contamination is randomly distributed on the surface of concrete chunks, it can be detected.
- 4) The 2" unshielded and 6" Shielded configurations can provide guaranteed detection of uranium at 1 FMPC average concentration and 3.54% enrichment for direct surveys with appropriate measurement time selection and are satisfactory TM-0324R0, WalScan Survey of Concrete Rubble Containing SNMin Sector 10, KMCushing Site Revision 0 NEXTEP Environmental, Inc.

for on-site survey methods for uranium. For scan surveys, a 15 cm/second scan speed is recommended to obtain up to 87% sensitivity.
9 RECOMMENDATIONS
- 1) Use of the shielded 3" x 0.5" Nal detector configuration is recommended for scans at a height of 6" above the surface of the concrete. Scans should be performed at a maximum scan speed of 15 cm/sec.
- 2) Direct measurements at 6" above the surface (shielded detector) should be performed at intervals to provide additional assurance of detecting any spots containing enriched uranium materials. A grid encompassing one survey point each 2-3 meters along the linear window axis would provide over 300 survey points.
- 3) Samples of the concrete should be collected if any direct measurement exceeds 540 cpm above background plus 2 sigma, which is equivalent to the counts from uranium at 3.54 % enrichment at an average concentration of I FMPC. For direct measurements using the 3" x Y2" shielded Nal detector, Table 3 gives an a priori background of 4,190 cpm. Two sigma of background is 130 cpm. Therefore, the a priori threshold for sampling is established as 4850 cpm. Adjustments can be made in the field as appropriate based upon the actual measured background and/or differences in enrichment or presence of thorium. The decision to dispose of materials rather than perform sampling should be left to the managers discretion.
