NX-503 Rev. 0 Page 3 of 10 NE Caisson Dewatering Well Assessment
Purpose:
This calculation/ assessment estimates the maximum residual source term surrounding the Northeast Caisson Dewatering Well and compares it with the DCGL for License Termination. To perform this assessment, sediment composite and grab sample results, and gross down-hole gamma measurements were evaluated.
Background Discussion:
During the performance of the Remediation Turnover Survey for the Caisson Area on January 4, 2018, two sediment samples were collected inside the pump casing for NE Dewatering Well #1. It was noted that water containing concrete fines material had been pumped to this well which had b_ecome inoperable during efforts to remove groundwater in the Caisson. The two samples had been collected using a hand auger through an access port cut in the side of the casing. The wet sample results of the two samples were evaluated and indicated elevated activity exceeding the DCGLEMc collectively by a factor of 3 for a 1 m 2 area. The following table shows the gamma results from the two samples collected and the EMC fraction calculated based solely on gamma spec results.

Since both characterization samples exceeded the DCGLEMu the NE well, along with the three other operational dewatering wells were excluded from the FSS unit which was independently surveyed by ORISE on January 11, 2018. As part of corrective actions for the NE well remediation to determine the extent of condition, additional characterization samples were collected of the material removed and material remnant remaining along with down-hole gamma characterization measurements to determine the extent of the residual source term outside the casing. This issue was captured SAPN 1439210.
For an operational perspective, it should be noted that the well logs indicate that water containing debris material which had accumulated in the suppression cha mber was pumped to the well on four separate occasions between February 2017 and May of 2017. After May 18, 2017, the well pump was inoperable and never returned to service.
Assumptions and Inputs:
Drawings indicate 12 inch ID, schedule 80, PVC well cas ing which became 14 inch OD casing to achieve the 12 inch minimum ID. The ASTM D1785 PVC pipe schedu le indicates that 12 inch PVC, schedule 80 piping should have a wall thickness of approximately 0.687 inches, an ID of 11.3 inch and an OD= 12.75 inch. 14 inch sched ule 80 PVC is 14 inch OD and 12.4 ID with a 0. 75 wall thickness. The 14 inch pipe
NX-503 Rev. 0 Page 4 of 10 NE Caisson Dewatering Well Assessment dimensions are used in the modeling: 12.4 inch ID and 0. 75 inch wall thickness. PVC pipe density ranges from 1.3 to 1.45 g/cc; 1.4 g/cc is used in the model.
The well was pumped down prior to taking individual measurements and sediment removal to the extent practical. For the purpose of the modeling, a dry well casing is modeled.
The cross-sectional sketch to the right indicates the basic modeling concept and it is not to scale. The MicroShield modeling geometry is called "Annular Cylinder - Internal Dose Point" and is intended to model piping with the source term either inside or outside the piping. In this case, the assumed source term is outside the piping. The thickness of the source term is initially estimated at 8 inches.
Assumed Source Term = 8 inches thick; modeled as concrete with density adjusted to 1.8 g/cc embedded in mud/soils of similar density.

NX-503 Rev.a Page 5 of 10 NE Caisson Dewatering Well Assessment Source term modeling was based on a mix of radionuclides expected to be present and contribute to the gamma response ofthe instrumentation: Cs-137 (Ba-137m); Co 60, Eu-152.The relative concentrations can be manipulated based on sample results. Top,of casing is at approximately -75 feet elevation for an overall height of the model of 23 feet (276 inches). However, modeling increments of 3 or 4 foot sections allows better assessment of varying dose rates along the well casing axis.
Source Term:
Several samples were collected from the NE Caisson Well during remediation activities as components and sediment were removed and analyzed by gamma spectroscopy. The results are summarized below:

The Eu-152 dominant sample (2018-0370) was composited from material removed above the pump and it is a reasonable assumption that whatever debris may have been transferred into the well when it was being used as an injection point the debris settled out on top of the pump.
Less than 1 pCi/g of Eu-152 was found in two samples below the pump or on the pump itself.
Case 1:
In Case 1, it is assumed that sample 2018-0373 best represents the residual source term in the gravel pack surrounding the well. Therefore, the relative ratio of Co-60:Cs-137:Eu-152 will be used in the model to represent the gamma source term measured by the scintillation detector.
3 The input to MicroShield is in units of uCi/cm so the following table is developed for ease of reference :

Co-60 1.3 pCi/g 1.4% 2.34 pCi/cm 2.34E-6 uCi/cm 3 3 3 Cs-137 93.4 pCi/g 97.9% 168.1 pCi/cm 1.68E-4 uCi/cm 3

In the model, the Cs-137 gamma source term is represented by the Ba-137m gamma emission at 94.6% of the Cs-137 concentration. Case 1 is more appropriate for the conservative assumption that a potential exposure pathway includes ingestion of the water at some point in the future. This estimate is based on results from a grab sediment sample collected using a clam-shell sampler inside the
NX-503 Rev.a Page 6 of 10 NE Caisson Dewatering Well Assessment casing nearing the completion of remediation activities with ~1' of material remaining in the bottom of the well. The decision to perform an EMC calculation based on the above sample results was considered inappropriate as the there was no corresponding proximal down-hole gamma measurement response indicating there were source materials in the 8" gravel fill material surrounding the casing.
Case 2:
In Case 2, it is assumed that sample 2018-0370 best represents the residual source term in the gravel pack surrounding the well. Therefore, the relative ratio of Co-60:Cs-137:Eu-152 will be used in the model to represent the gamma source term measured by the scintillation detector.
The input to MicroShield is in units of uCi/cm 3 so the following table is developed for ease of reference:
Nuclide Sample 2018-0370 Fractional density corrected MicroShield input 3
Co-60 1.5 pCi/g 2.6% 2.7 pCi/cm 2.7E-6 uCi/cm 3 3 3 Cs-137 20.6 pCi/g 36.3% 37.1 pCi/cm 3.71E-5 uCi/cm 3

In the model, the Cs-137 gamma source term is represented by the Ba-137m gamma emission at 94.6% of the Cs-137 concentration. Case 2 is more appropriate for the assumption that the solid material in the gravel pack moves to the surface in an intrusion scenario.
Limitations:
MicroShield only allows definition of a single source term at a time. Therefore, in the model concept shine through the end cap at the bottom of the well is not considered. A higher measured response at the bottom of the well should be expected if the source term is uniformly distributed.
Modeling is established assuming that the detector is at the centerline of the well casing.
However, based on the ID of the well casing, there may be some bias in individual measurements based on proximity to the casing wall. No stand-off was built-in to minimize this geometry error. The average of several measurements should minimize this bias.
Method Summary / Data:
Down-hole gamma survey data was collected (HBPP-CHAR-CAISSON-DW-00) at six inch increments using a 3" by 3" thick Nal scintillation detector. The collected data allows averaging several measurements along a segment of the well. The multiple measurements identify non-uniformities in the source term and minimize the bias toward individual measurements. From the data plotted in Figure 2, the ncpm line depicts the raw down-hole gamma measurement adjusted for instrument background. The smoothed line shows averaged ncpm data for each 1' span (three data points averaged, the segment 6" above, the original segment, and the segment 6" below). Note that the O' segment corresponds to the top of the casing, and the -22.5' location is the segment located 1' above the casing end cap bottom which was inaccessible because of water. It is also interesting to note that the dominating peak extents (15,000-20,000 ncpm)
NX-503 Rev. 0 Page 7 of 10 NE Caisson Dewatering Well Assessment range from the -7.5' to -14.5' elevation. This elevation range spans the original sediment characterization location collected during the remediation turnover survey from the top layer of material on top of the pump (estimated to be collected at the -10' segment location). The detector response observed for this region was likely from concrete slurry-like materials deposited in the casing which migrated through the perforated portion of the casing during
. remediation activities within the active core region and thus represents a Eu-152 dominated source term ..

This conversion factor is based on a Cs-137 source term, however, for the two MicroShield cases considered the dose rate does not change whether the Cs-137 dominant source term is assumed or the Eu-152 dominant source term is assumed.
The Ludlum detector is partially shielded on the back side so the conversion factor is likely based on a 2 pi response rather than the 4 pi response predicted in the MicroShield model. Therefore, the conversion factor is adjusted to compensate for the detection efficiency in the environment to 1200 cpm per uR/hr. Using the 1200 cpm per uR/hr conversion factor, text is overlaid on the graphic above to indicate an approximate observed dose rate. Note that only the exposure
NX-503 Rev.a Page 8 of 10 NE Caisson Dewatering Well Assessment conversion graphic is adjusted. The ncpm data results have only been adjusted for instrument background.
Interpretation of the data plot above reveals that the well effect is likely responsible for the essentially linear detecto r response from the -22.5' to -12.5' segments. Starting around segment
-12, the detector starts indicating increasing activity from the source term in the gravel pack with a peak response around the -10' segment. The decreasing response from the -9.5' to the -8' segment provides confidence that the deposited source term is likely in a gravel pack volume of approximately 2' in height. It also suggests that the source term did not move vertically within the gravel pack, which is expected given that the well pump has been out of commission since May 2017.
Calculations:
Using the source terms above and MicroShield 9 (See Appendix 1) with the detector at a center-point in a 4 foot section of the casing, initial calculations indicate a dose rate inside the well casing:
Case 1 Source term (Cs-137 dominant) = 81 uR/hr:
75 uR/hr ( 0.6 MeV), 2.5 uR/hr (1.0 Mev), and 3.3 uR/hr (1.5 Mev). These energies reflect the Cs-137 dominant source term and the Co and Eu contribute about 7% to the overall dose rate.
The total residual activity to generate this dose rate would be about 75 uCi around the 4 foot section of casing.
Case 2 Source term (Eu-152 dominant)= 80 uR/hr 5 uR/hr (0.3-0.4 MeV),18 uR/hr ( 0.6 MeV), 8 uR/hr (0.8 MeV), 26 uR/hr (1.0 Mev), and 22 uR/hr (1.5 Mev). These energies reflect the Eu-152 dominant source term and Cs contributes about 23% to the overall dose rate. The total residual activity to generate this dose rate would be about 44 uCi around the 4 foot section of casing. In case 2, the source term is somewhat shorter lived than in the Cs-137 dominant case (T112Cs-137 = 30 yrs; T112 Eu-152 = 13.6 yrs).
The MicroShield predicted dose rates (80 uR/hr) assume the removed sediments sample represents the residual source term concentration and is nominally 5 times the actual measured residual activity. The residual measured activity is actually 19% of that concentration (i.e. 10-18 uR/hr vs. 80 uR/hr).
Comparing the observed dose rate with the MicroShield predicted dose rate a correction to the sa mple
- concentrations can be made based on the ratio of the observed to predicted dose rate:
15 uR/hr = the maximum observed dose rate in a 4' section from Figure 2 in the -8 to -12 ft range 80 uR/hr = the predicted dose rate based on sample 2018-0370 results in a 4' section (i.e. Case 2)
The residual concentration is 15/80 or 19% of the sample concentration.
