SUMMARY

The radiological characterization of the High Level Waste (HLW) Canister Interim Storage Area is the subject of this report. Characterization was performed in accordance with the Field Sampling Plan (FSP) for Task Order 4, West Valley Demonstration Project Environmental Characterization Services (SEC 2012).

The objective was to perform a characterization survey by collecting soil samples and performing a gamma walkover survey (GWS). The soil samples were analyzed for 18 Radionuclides of Interest (ROIs) and 12 Potential Radionuclides of Interest (PROIs) as described in the Characterization Sampling and Analysis Plan (CSAP) (DOE 2011). The GWS was performed with a field instrument for detecting low energy radiation (FIDLER) and a standard 2-inch diameter by 2-inch tall sodium iodide (Nal) detector.

1.0 INTRODUCTION

The West Valley Demonstration Project (WVDP) (established to implement the WVDP Act) is located on approximately 152 acres within the 3,345-acre Western New York Nuclear Service Center (WNYNSC), owned by the New York State Energy Research and Development Authority (NYSERDA) in rural Cattaraugus County, about 35 miles south of Buffalo, New York. The WVDP site is complex, involving a large number of potential radionuclides of concern and a variety of historical processes and events that are known to have or may have released contaminants into the environment. Known affected environmental media include surface soils, subsurface soils, groundwater, surface water, and sediments. The decommissioning of the WVDP site will involve a sequential set of activities that will vary significantly depending on the exact location and activity purpose.

The WVDP is a unique operation within the U.S. Department of Energy (DOE). The West Valley Demonstration Project Act of 1980 directed the Secretary of Energy to undertake five major activities, as follows:

• Solidify the liquid high level waste (HLW) stored at WNYNSC into a form suitable for transportation and disposal (completed);

" Develop containers for the solidified HLW suitable for permanent disposal of the HLW (completed);

" Transport the waste to a federal repository for disposal (pending);

• Dispose of low-level radioactive waste (LLRW) and transuranic (TRU) waste produced by the Project (in progress); and

• Decontaminate and decommission the HLW storage tanks (PUREX and THOREX HLW tanks deactivated, July 2003), the HLW solidification facilities (in progress), and any material and hardware used in connection with the Project (in progress).

Decommissioning of the site will occur in two phases. Phase I of the decommissioning will entail removal of the Main Plant Process Building, the Low-Level Waste Treatment Facility, and certain other facilities within the WVDP area, which is known as the project premises. These activities will clean up much of the project premises to standards that will not prejudice decisions on the approach for Phase 2, which will complete the decommissioning. The Phase 2 decision shall be made within 10 years of the Record of Decision and Findings Statement documenting the Phase I decisions. Phase 2 actions will complete the decommissioning or long-term management of those facilities remaining at WVDP and WNYNSC following the completion of Phase I decommissioning.

One activity conducted as part of the Phase I decommissioning is the construction of the new HLW Canister Interim Storage Area. This facility will be constructed on the south plateau near the rail spur. The facility will consist of a reinforced concrete pad of sufficient size and load capacity to store 57 vertical concrete storage casks containing 275 canisters of vitrified HLW, two evacuated canisters, and two drums of spent nuclear fuel debris.

The radiological characterization of the location where the HLW Canister Interim Storage Area will be constructed is the subject of this report. Characterization was performed in accordance with the Field Sampling Plan (FSP) for Task Order 4, West Valley Demonstration Project Environmental Characterization Services (SEC 2012).

UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 1.1 Site Description The HLW Canister Interim Storage Area is in the southwest comer of the WVDP premises. It consists of approximately 4.8 acres, 3 of which are covered with gravel (referred to as hardstands) and 1.8 acres are open land. When the characterization was performed, much of the site was covered with knee to waist high grasses and weeds. There were several stands of chokeberry bushes, a few small trees, and three drainage features. These drainages converge into the northernmost drainage which is the headwaters of Erdman Brook. Figure 1-1 shows an aerial map of the study area.

For planning purposes, the WVDP premises have been divided into Waste Management Areas (WMAs) as described in the Phase I Decommissioning Plan (DP) (DOE 2009). There are 12 WMAs, numbered I through 12. The HLW Canister Interim Storage Area is located in the southern ends of WMAs 6 and 10.

WMA 6 is approximately 14.5 acres and contains a variety of facilities, including the Rail Spur, the Above-Ground Petroleum Storage Tank, the Sewage Treatment Plant, the New Cooling Tower, the two Demineralizer Sludge Ponds, the Equalization Basin, the Equalization Tank, the South Waste Tank Farm Test Tower, the Road-Salt and Sand Shed, and the LLW Rail Packaging and Staging Area. There is an area west of the site rail spur, referred to as the vitrification hardstand, in the southern portion of WMA 6. This vitrification hardstand, along with a grassy area to its north, is where a portion of the HLW Canister Interim Storage Area will be constructed.

WMA 10 is approximately 30 acres and contains support and service facilities. WMA 10 includes the Administration Building, the Expanded Laboratory, the New Warehouse, the Security Gatehouse, the Meteorological Tower, the Main Parking Lot, and the South Parking Lot. In addition, concrete slabs and foundations from several removed structures remain in place, along with the Former Waste Management Storage Area and various hardstands. One of these hardstands was part of the vitrification hardstand. This patch of hardstand is not contiguous with the hardstand in WMA 6. This patch of hardstand in WMA 10 is in the area where the HLW Canister Interim Storage Area will be built. A grassy area to the south of this hardstand is also included in the area where the HLW Canister Interim Storage Area will be constructed.

The conceptual site models for WMAs 6 and 10, presented in the Characterization Sampling and Analysis Plan (CSAP), indicate little reason for the soils at the HLW Canister Interim Storage Area to be contaminated (DOE 2011a). However, in 1990 and 1991, gamma exposure rate measurements ranged from II - 25 pR/hr at several locations where the HLW Canister Interim Storage Area will be constructed. These readings are elevated above typical natural background readings of 10 micro-R/hr or less. Also, during drilling to characterize geotechnical characteristics of the area, fill material was found from 4.5 feet (ft) to 11 ft throughout the area.

Field screening measurements for gamma radiation collected during the geotechnical investigation did not detect radioactivity above natural background levels.

1.2 Objectives The primary objective of the FSP was to perform a characterization survey of surface and subsurface soils at the HLW Canister Interim Storage Area. The characterization survey April 2013 1-2

IUNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 2.0 CHARACTERIZATION ACTIVITIES AND RESULTS The site was characterized by performing GWSs, collecting soil samples with a hand auger and with a geoprobe, and performing a civil survey to record the sampling locations. Systematic and biased locations were sampled. Gamma radiation was measured at each sampling location. The soil cores were scanned for gross gamma radiation, and down-hole gamma logs were performed, where feasible. Lithologic logs were created at each soil sampling location. A portion of the site was cleared to allow access for the GWS. In addition, two background reference areas were surveyed using GWS and by collecting soil samples.

The work performed is specified in the FSP for Task Order 4 (SEC 2012) and briefly summarized in this section. FSP data collection results are presented and interpreted in this characterization report.

Gross gamma measurements were made with both the field instrument for detecting low energy radiation (FIDLER) and sodium iodide (Nal) detector for 30 seconds each, 15 centimeters (cm) above the ground surface at the location where each soil sample was collected. The gross gamma measurements were made before a soil sample was collected.

According to the FSP, down-hole gamma logs were to be performed when feasible, in the holes where the geoprobe cores were taken in areas where the surface cover type was hardstand. When this was infeasible, the cores were to be scanned for gamma radiation after extraction from the hole. Down-hole logs met this specification.

A background area, Background Reference Area 1, was characterized both for gamma radiation signal and by collecting soil samples. Information collected at Background Reference Area I is discussed in the West Valley Demonstration Project Terrestrial Background Study (SEC 2013a).

This area had sand and gravel geology. The lithologic logs for each sampling location shown in Appendix E revealed that the fill material that was present and was sampled to a depth of at least I m in the study area was typically sand and gravel, similar to Background Reference Area 1.

The results from Background Reference Area I are compared to results from the three survey units for this reason.

2.1 Gamma Walkover Survey Brush was cleared from the site in all areas that were not a wetland or on a slope such that the work would be unsafe. There were wetlands with a stand of cattails at the northern end of the study area near Erdman Brook.

SEC performed a GWS of 100% accessible surfaces of the HLW Canister Interim Storage Area and at Background Reference Area 1 with a 2-inch diameter by 2-inch tall Nal detector and a FIDLER detector. The FSP required a 100 percent survey of accessible areas with the FIDLER.

While not required, 100% of accessible areas were also surveyed with the Nal detector to address an FSP objective of evaluating results of different detector types. An area on the northeast comer of the survey area was not surveyed. It included both uneven terrain and vegetation that was too large to be cut safely with the available brush cutting tools. Approximately 450 square meters (m-) of this area is designated as wetlands based on information provided by the DOE Project Manager and was left undisturbed.

April 2013 2-1

UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 The detectors were coupled to a Large Area GPS Gamma Survey System (LAGGSS) consisting of a Trimble Global Positioning System (GPS) unit coupled to a Nal detector and to a FIDLER detector to survey the area and subsequently download and plot the results to provide a visual map and the relative gross gamma radiation. The SEC LAGGSS system delivers multiple gross gamma radiation results and coordinates per square meter of surface area. The raw data was processed into graphic depictions of gamma ray count contours to aid in the selection of biased sample locations. The data was also used to compare the relative sensitivity of the Nal and FIDLER detectors for the mix of radionuclides present.

The walkovers were performed using the cart shown in Photograph 4 in Appendix A in large open areas of the site. Detectors on the cart were positioned no farther apart than 85 cm to assure the minimum data density of one measurement per m 2 would not be exceeded. A technician walked with the detector in other areas of the site where cart access was difficult or impractical.

The GWS recorded a survey measurement and a paired position approximately every second.

The GPS attained sub-meter accuracy (x, y data). Data were electronically logged and included coordinates in New York West State Plane coordinates (NAD83). Coordinates were measured with a density of approximately six points per square meter, exceeding the FSP requirement of attaining at least one measurement per square meter. The data contained counts per minute (cpm), northing and easting (x, y), and position dilution of precision (PDOP), date, and time. The average walkover speed was approximately 0.5 meters per second (m/s) in accordance with the survey plan.

Figure 2-1 shows contours of the GWS results for the FIDLER and Figure 2-2 shows contours of the GWS results for the Nal detector.

There were HLW vitrification vessels along the southeastern boundary of the study area as shown in Photograph 4 in Appendix A. These vessels were in an area posted as a Radiation Area, meaning that the gamma exposure rate at 30 cm from the surfaces exceeded 5 millirems per hour (mR/hr). This Radiation Area caused significant gamma radiation signal, referred to as shine, on the hardstand area in the southeastern portion of the study area. FIDLER detectors were shielded with 1 inch thick lead collars placed on the detectors to collimate them such that the field of view was directly below the detectors. The results of the measurements performed with the collimated detectors are shown in Figure 2-3.

The lead shielding reduced the gamma-ray signal and reduced the areal extent of the hardstand that was affected by the shine. The shielding, however, did not eliminate the shine. Shine still affected the detector as it entered above the lead collar and travelled through the photomultiplier tube into the detector. The ability to determine if there is contamination on the hardstand area affected by the shine is still greatly inhibited. Soil sample results were relied upon to characterize the area affected by shine. Future work with differing shielding configurations and thicker shielding is recommended. Shielding the smaller Nal detector may prove effective as a longer collar will eliminate shine entering from above the collar. The weight of the longer collar will be offset by the smaller diameter of the detector.

Hardstand areas, covered with gravel, had lesser GWS readings than did areas where the surface cover was soil, except when influenced by radiation from the vitrification vessels. The two largest areas of hardstand are in the northwest part of the site and the southeast portion of the site.

UNCONTROLLED DOCUMENT I Radiological Characterization Report (RCR) (T04) - Rev. 0 Other than the southeastern hardstand influenced by the vitrification vessels, the FIDLER survey data (Figure 2-1) shows four other areas of elevated gamma measurements. Refer to Figure 2-4 which shows a side-by-side comparison of FIDLER and Nal GWS data. The areas of elevated radiation are numbered on Figure 2-4 for ease of discussion.

Area 1 is the southeast hardstand affected by shine from the vitrification vessels. Area 2 is in the northwest side of the northwestern hardstand area. This was a small depression near the road where the surface cover was more soil than hardstand. The elevated gamma readings are not likely indicative of contamination; rather the readings are likely caused because the bowl forming the depression exposes a greater surface of soil with naturally occurring radioactivity to the field of view of the detector. This will be referred to as the "well-counter" effect. The remaining areas, numbered 3 - 5 on Figure 2-4, occur in the surface soils areas. The likely reason for the elevated readings in these areas is the well-counter effect. Area 3 on the northeast corner of the southern surface soil unit was on the edge of an elevation change. There was no visual evidence that distinguished this area from other areas that were typical in the surface soils area.

Area 4 on the southern portion of the northern surface soils unit was split by the area that was designated as wetlands. The western side of this area was a slope that drained toward the wetlands. Again, there was nothing present to visually distinguish it from other surface soils areas. Finally, Area 5 on the northern portion of the surface soils area was a grassy area located between the two surface drainage features.

The Nal survey provided less survey data to analyze in the five elevated areas detected by the FIDLER survey because the data density was less. However, the Nal survey produced similar results in four out of the five areas identified by the FIDLER. The exception was Area 4, on the south side of the north surface soil area. The Nal data was not as dense in this area as was the FIDLER data set.

One of the objectives of this survey was to evaluate the performance of the FIDLER detector versus the Nal detector. Qualitatively, the FIDLER appears to reveal areas with elevated radioactivity better than does the Nal, albeit likely from surface feature effects and not radioactive contamination. Even if this conclusion is influenced more by the higher data density collected with the FIDLER detectors, future GWS only need to be performed with one of the detectors.. The cost of surveying with both types of detectors does not appear to be justified by the extra data that was acquired. The FIDLER is better used in areas that are not influenced by shine. The large diameter and shape of the FIDLER makes it difficult to effectively collimate to help eliminate shine. The Nal detector is easier to collimate and may prove useful to correlate static gamma radiation readings to soil concentrations in areas that have soil contaminated with radioactivity. A static reading means holding the detector above the ground surface for a predetermined time such as 30 seconds and recording the counts registered by the detector.

Table 2-1 provides a summary of the gamma walkover statistics for each detector type for the three survey units. Provided are measurement minimum, maximum, average, standard deviation, median, and average walking velocity.

• Three drainage linear features totaling 380 rn.

2.2 Soil Sampling Shallow surface and deep surface soil samples were collected in each survey unit and in two background reference areas. For the purposes of the discussion in this section, shallow surface soil is referred to as soil collected from 0 - 15 cm below the surface or hardstand material. Deep surface soil is referred to as soil taken from a depth of 15 - 100 cm below the surface or hardstand. These designations for surface soil are used to avoid confusion with the definitions in the Phase I Decommissioning Plan where surface soil is defined as soil from 0 - 100 cm below ground surface and subsurface soil is defined as soil deeper than 100 cm below ground surface (DOE 2009).

Surface soil samples to a depth of 15 cm below ground surface or below hardstand material were collected using a 10 cm diameter hand auger. Samples deeper than 15 cm below ground surface or below hardstand material were collected using direct-push drilling methods except in some instances when the drill rig could not access the location. This happened at three locations in Survey Unit 3 and one location in Survey Unit 1 where the location was on the bank above the headwaters to Erdman Brook. In these cases the hand auger was used to acquire samples to I m or where refusal occurred due to large cobbles in the drainages and in one case due to rocks in the survey unit comprised of exposed surface soils.

UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 Seven potential biased sample locations were proposed after reviewing the GWS results. Five locations were sampled based on discussions with DOE representatives. The biased locations where samples were collected were numbers 1, 2, 4, 5, and 7.

A sufficient volume of soil was collected allowing all 18 ROls and 12 PROIs to be analyzed according to the methods shown in Table 1-1. Sufficient sample volume was approximately 900 g. By collecting surface soil samples from 10-cm diameter holes 15-cm deep and subsurface soil samples from 5-cm diameter holes, a sufficient volume of media was collected.

A 30-second static FIDLER count and a 30-second Nal detector count were performed at a distance of 15 cm above the ground surface prior to acquiring samples. A physical description of the material sampled, date, and time was included in the field logbooks and is provided with the lithologic logs in Appendix E. Additionally, the location (coordinates) of the sample was recorded in NY State Plane West NAD83 with a quality of+ a hundredth of a foot (+ 0.01 ft) for each sample. Table 2-2 includes the sample count rates that were converted to cpm (30 second measurement multiplied by two).

Five pairs of static counts, both Nal and FIDLER, were not recorded for Survey Unit 2 before the samples were collected as specified in the FSP. These sample locations are shown with an asterisk in Table 2-2. The data was collected after the samples had been extracted.

Hand-auger samples were placed in stainless steel mixing bowls and homogenized with a stainless steel trowel and packaged as samples. The mixing bowls were placed on plastic sheeting to prevent contamination.

Samples obtained by direct push methods were collected in acetate liners. Once removed from the steel collection tube, the acetate liners were cut open and the sample was extracted and placed into a mixing bowl for homogenization and packaging. Such sample collection was performed on a table that was covered with plastic sheeting. The typical sample collection approach is shown in Photograph 5 in Appendix A.

Sample tools and drilling equipment was wiped clean with masslin and 409 cleaning solution as necessary to remove visible dirt. Tools were scanned for alpha and beta-gamma radiation and a swipe for radioactive contamination was collected. The swipe was counted in a low background counter in the sampling van. No gross alpha radiation exceeding the instrument lower critical level (Lc) of 1 cpm was ever detected on the sampling equipment. No gross beta-gamma contamination exceeding the Lc of 19 cpm was ever detected on the sampling equipment. The swipe counter is shown in Photograph 6 in Appendix A.

Surface and subsurface samples were scanned for gamma radiation before they were homogenized. This was done to help determine if there are discrete horizons of radioactive contamination in the soil cores. None were found.

Figure 2-5 shows the systematic and biased soil sampling plan for the study area. Most, but not all, of the planned locations were sampled, as discussed in subsections below. Included on the figure are the locations of all three survey units along with biased sample locations. Systematic samples for Survey Units I and 2 sample points were located using a random start triangular grid developed before field mobilization.

• Measurements made after the soil sample was collected.

Unit 3 was one per approximately 30 m. Details regarding the rationale for the numbers of samples collected are specified in the FSP and are not repeated herein. Some locations were moved during the field work to: 1) locate in a nearby spot where contamination may have accumulated such as a depression or swale, 2) avoid potential contact with buried utilities as specified on the WVDP Ground Disturbance Permit, and 3) to gain better accessibility.

UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 Some soil samples were archived per the FSP. A table showing the archived samples is provided in Appendix B. The sample holding time for all samples except tritium is 180 days per the FSP.

The sample holding time for tritium is 45 days and the tritium samples sent for analysis were kept on ice at 4 degrees C or less. If any of the archived samples are to be analyzed, the holding time for tritium will have been exceeded in all cases. None of the archived tritium samples are maintained at 4 degrees C.

The soil sampling specifications in the FSP were slightly different for each of the survey units.

These differences are discussed and the laboratory analytical results are provided in Sections 2.2.1 through 2.2.3. Field changes or other deviations from the FSP, notably when sample locations were moved, are discussed. The gamma scans of the soil cores after extraction are also reported.

2.2.1 Discussion of Results Sample results were reviewed in light of background concentrations taking into account the error associated with sample results and minimum detectable activity (MDA). A discussion of background concentrations is provided in reference SEC 2013a.

Background comparisons are based on results from the reference area surface soil sampling. The 95 percent upper tolerance limit (UTL) was estimated for each radionuclide that could be expected to be present in measurable quantities in background soils (i.e., naturally occurring radionuclides and those anthropogenic radionuclides present in background surface soils due to historical fallout) based on the 0 - 15 cm deep sample results and the 15 - 100 cm deep sample results. The raw sample results were used to perform this calculation regardless of whether sample results were considered detections or not. The naturally occurring radionuclides evaluated in this manner were carbon-14, tritium, uranium-234, uranium-235, uranium-238, actinium-227, protactinium-231, radium-226, and radium-228. Review of the overall data set including the background sampling results revealed that cesium-137 was the only anthropogenic radionuclide found in fallout with enough results in excess of the MDA to compute a meaningful 95 percent UTL. Sample results for these radionuclides were considered inconsistent with background if the activity concentration of one or more radionuclides exceeded its respective 95 percent UTL. All other ROIs and PROls were considered inconsistent with background when a soil sample result was greater than three times its reported uncertainty (DOE 201 la).

One objective of the sampling effort was to evaluate whether additional PROIs should be added to future sampling efforts. Review of the gamma spectra for the samples did not reveal that any other gamma-emitting radionuclides might be present. No additional gamma-emitting PROIs were identified.

2.2.2 Survey Unit 1 - Exposed Surface Soils Eight systematic sample locations were required per the FSP because the survey unit was approximately 8,000 mi2 . Eight locations were sampled. The FSP required collection of a 0 - 15 cm sample and a 15 - 100 sample. Additionally, the FSP required collection and archival of a I -

2 m sample and that the sample not be comprised of hardstand or fill. Fill was found under each sample location. The FSP was clarified such that a I--m long core extending into the Lavery till underneath the fill was collected and archived.

April 2013 2-12

UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 Location 1-1 was moved 3 m east. It was at a location where sampling below 2/3 m was prohibited by the Ground Disturbance Permit.

Location 1-7 was on a slope and could not be reached safely with the drill rig. The 0 - 15 cm depth was sampled with the hand auger ahd the sample was sent for analysis. The 15 - 100 cm depth was attempted with the hand auger and a large rock prevented sampling beyond 58 cm.

Location 1-8 was moved because it was inaccessible. It was in a thick stand of chokeberry bushes, on a slope and behind a stand of mature trees. The 0 - 15 cm and 15 - 100 cm samples were collected using the hand auger. Because the drill rig could not access the area, no sample of I m length was collected into the Lavery till and archived.

Sample 1-6 at a depth of 15 - 100 cm was split into two samples as a field duplicate.

The tables in Appendix C contain the analytical results for the ROIs and PROIs. These tables include the sample results, total propagated uncertainty (TPU), and the MDA. The TPU is the analytical error at two standard deviations taking into account all potential error sources, including sample counting error, background counting error, error in tracer yield, etc. The soil sample analytical data is evaluated in light of background sampling in Background Reference Area I and the MDA.

The results are summarized in Tables 2-3 and 2-4 for the ROIs and PROIs, respectively. The tables show the analytical result along with notations whether the result exceed the MDA and were considered inconsistent with background according to the criteria specified in Section 2.2.1.

Values shown in bold font were determined to exceed the analytical MDA. Underlined values reflect whether the sample was determined inconsistent with background.

There were analytical method interferences that biased the results for iodine-129, radium-226, actinium-227, thorium-229, and protactinium-231. This is discussed in the Radiological Interferences Technical Memorandum (SEC 2013b).

2.2.3 Survey Unit 2 - Hardstand Thirteen systematic sample locations were required by the FSP because the survey unit was approximately 13,000 mi. The FSP required collection of a 0 - 15 cm near surface sample and a 15 - 100 cm deep surface sample below the surface of the hardstand material. Therefore the depth intervals for sample results did not begin at a depth of 0 cm; rather, the top of the sampling interval begins at a depth greater than 0 cm.

The FSP required collection and archival of a 1 - 2 m sample and that the sample not be comprised of hardstand or fill. Fill was found under each sample location. The FSP was clarified such that a 1-m long core extending into the Lavery till underneath the fill was collected and archived.

Twelve locations were sampled. Location 2-1 was not sampled. It was in an isolated area of hardstand at a location where sampling below 2/3 in was prohibited by the WVDP Ground Disturbance Permit. It was determined to use the location as a later biased sample and save the April 2013 2-13

UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (104) - Rev. 0 analytical costs. The sampling rationale provided in the FSP showed that approximately nine samples per survey unit would satisfy the MARSSIM-based statistical design such that collecting this sample was determined unnecessary.

Location 2-9 was at a location where sampling below 2/3 m was prohibited by the WVDP Ground Disturbance Permit. The location was moved approximately 2 m east and sampled.

Two field duplicates were taken from this survey unit. The field duplicates were taken at Location 2-13.

The sample from 0 - 15 cm below the hardstand and the sample from 15 - 100 cm below the hardstand were split into field duplicates. One field duplicate was supposed to be collected from each survey unit; however, the field duplicate from Survey Unit 3 was not collected. This mistake occurred because all samples had been sent to the laboratory for analysis from Survey Unit 3 before the requirement for collecting field duplicates was recognized. The second field duplicate from Survey Unit 2 was taken to compensate for this.

The tables in Appendix C contain the analytical results for the ROIs and PROIs. The results are summarized in Tables 2-5 and 2-6 for the ROI and PROI, respectively.

2.2.4 Survey Unit 3 - Drainage Features Thirteen sample locations were set in the FSP, located approximately 30 m apart in the three drainage features. Twelve locations were sampled. The FSP required collection and analysis of a 0 - 15 cm near surface sample. The FSP specified collection and archival of a 15 - 100 cm deep surface sample. When field work was performed, it was found that some of the Survey Unit 3 sample locations were on fill.

Therefore the sampling approach in the FSP was modified to collect and archive an additional I - 2 m core in the Lavery till below the fill.

Location 3-6 was moved. As originally laid out, it was not in a drainage feature. The location was moved down-slope and 10 m to the east. Both the samples were collected with the hand auger because the location was inaccessible to the drill rig. The first sample was collected from 0 - 15 cm and sent for analysis. Auger refusal occurred at 46 cm when drainage cobbles were encountered.

Location 3-9 was not sampled. It was in a deep ravine on rocks and cobbles. There was no soil to sample and there was no reasonable location to move the sample point. Because nine locations would meet the MARSSIM statistical design, twelve locations were considered acceptable to characterize Survey Unit 3.

Location 3-13 was moved 8 m north and east to better place it in the drainage feature. This location was sampled entirely with the hand auger because it could not be accessed by the drill rig. The 0 - 15 cm sample was collected. The second sample was collected to 68 cm where auger refusal occurred due to drainage cobbles.

The tables in Appendix C contain the analytical results for the ROIs and PROIs. The results are summarized in Tables 2-7 and 2-8 for the ROI and PROI, respectively.

UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 2.2.5 Biased Samples Biased sample Location 7 was placed in Survey Unit 1. It was placed at a specific location with elevated gamma radiation signal determined during the walkover surveys. Biased sample Locations 1, 2, 4, and 5 were placed in Survey Unit 2. These were placed in the area influenced by shine from the vitrification vessels. Tables 2-9 and 2-10 provide evaluations of biased sample ROIs and PROIs, respectively; Biased samples were targeted toward the area affected by shine to characterize this area where the GWS could not discern potentially contaminated areas. Biased samples were not taken from other locations with higher gamma radiation signal because this elevated signal was likely due to the well counter effect and because systematic samples were located near these areas.

2.2.6 Down-hole Gamma Logs Down-hole gamma logs were created for all boreholes in the hardstand material. The logs were taken with a '/2-inch by 1-inch Nal detector. The smaller detector was used so that it could fit into the borehole. Note that the smaller volume detector has a lower efficiency and a lower count rate response than the bigger Na! detectors used for the GWSs.

The maximum depth logged was 10 feet because either the hole collapsed or water was encountered. The logs are shown in Appendix D. The results of all the logs are indicative of background in the holes. None of the logs indicate increased count rates indicative of a specific horizon of contamination.

2.2.7 Lithologic Logs The lithologic logs for each sampling location are shown in Appendix E. Lavery till was considered native soil. Other material above the till had characteristics of unconsolidated sand and gravel fill. There was a wet zone of perched water overlying the dense clay till. The depth of fill material ranged from 2.7 m to 4.1 m and was typically 3 m in all locations in Survey Unit 1.

UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 3.0 QUALITY ASSURANCE Quality assurance (QA) information was collected for soil data and for the GWS data. Soil QA data is presented in Section 3.1 and GWS QA data is presented in Section 3.2.

The soil analytical data was validated and verified by an independent third party. Ten percent of the data was validated and 100 percent was verified. The data validation is discussed in Section 3.3. Verification of the data was performed to assure that the electronic data deliverable matched the hard copy laboratory reports with 100 percent accuracy.

3.1 Soil Sample Ouality Assurance The characteristics of precision, accuracy, representativeness, completeness, comparability, and sensitivity are discussed in Sections 3.1.1 through 3.1.5, respectively.

3.1.1 Precision Precision is a measure of the degree to which two or more measurements are in agreement.

Precision in the laboratory results was assessed through the calculation of relative percent differences (RPDs) for the replicate laboratory control samples (LCSs) and laboratory control sample duplicates (LCSDs). Precision was also evaluated for field duplicate sample analyses.

According to the CSAP, precision reflects measurement variability as observed in repeated measurements of the same subsample; for radio-analytical methods, the required precision is reflected by required method detection limits (DOE 201 Ia). In other words, specifying the required detection limits is equivalent to specifying the required method precision; therefore, specific tolerance limits for precision were not set in the FSP. The results of precision evaluations are simply reported.

Field duplicates are the least precise because they introduce all sample uncertainty from field sample collection through laboratory analysis. Field duplicates are collected as sample splits from the same sample mass. Two samples were extracted after homogenization with hand tools.

These two samples were sent separately for laboratory analysis and the results were compared to establish a measure of precision.

The RPD calculation allows for the comparison of two analysis values in terms of precision with no estimate of accuracy. RPD is calculated as:

RPD = ( . M 100 Where:

m = First measurement value, M = Second measurement value, and M = Mean value of M and m.

LCS and LCSD samples were analyzed for the following:

April 2013 3-1

UNCONTROLLED DOCUMENTI Radiological Characterization Report (RCR) (T04) - Rev. 0

• Americium-241 by alpha spectroscopy and gamma spectroscopy,

• Carbon-14 by liquid scintillation,

• Cobalt-60 by gamma spectroscopy,

• Cesium-137 by gamma spectroscopy,

• Tritium by liquid scintillation,

• Neptunium-237 by alpha spectroscopy,

" Plutonium-239/240 by alpha spectroscopy,

" Strontium-90 by chemical extraction and gross beta analysis,

• Technetium-99 by chemical extraction and liquid scintillation,

• Uranium-232 by alpha spectroscopy, and

• Uranium-238 by alpha spectroscopy.

The LCS and LCSD RPD for gamma spectroscopy were all performed using a calibration check source with an activity of 40,000 to 70,000 disintegrations per minute (dpm) in the radionuclide-specific energy channel for the spectrometer. While this is a measure of precision, this amount of radioactivity (dpm) is significantly higher than the amounts measured in the actual samples. The LCS and LCSD RPD for liquid scintillation, alpha spectroscopy, and gross beta analysis were calculated at concentrations that were representative of the soil Cleanup Goals (CGs) established in the Phase I DP (DOE 2009).

There were 103 LCS and LCSD data pairs that were evaluated. In 80 percent of the data pairs, the RPD was 10 percent or less. Analyses for tritium, carbon-14, americium-241, plutonium 239/240, strontium-90, and uranium-232 each had at least one RPD result greater than 10 percent.

The Normalized Absolute Difference (DER) between the LCS and LCSD is used to determine that the results do not differ significantly (at the 99 percent confidence interval) when compared to their respective combined standard uncertainty. A DER of less than or equal to three is considered acceptable.

DER = IS- DI 2 +(csuD) 2

/(csus)

Where:

S = LCS result D Duplicate result CSUs = Combined Standard Uncertainty of the LCS CSUD = Combined Standard Uncertainty of the duplicate Ninety-eight percent of the DER calculations for the LCS and LCSD were three or less.

Precision for the field duplicates was calculated for cases when both samples analyzed for the same analyte had results greater than the MDA. Precision for field duplications was determined for cesium-137, uranium-233/234, radium-226, radium-228, and thorium-232. Precision is shown as both the RPD and the coefficient of variation (CV) in Table 3-1. The coefficient of variation is less than 20 percent in three of the four samples. This is considered acceptable. The CV for the fourth duplicate pair is relatively high. This was a duplicate set of samples taken April 2013 3-2

One split contained more fine grained material than the other. This may be the reason for the difference in the results.

3.1.2 Accuracy Accuracy addresses the potential for bias and lack of precision in laboratory analytical results and is typically monitored through the use of standards, spikes, blanks, and control charts, as appropriate, depending on the method. The accuracy requirement for off-site laboratory analyses set in the CSAP is a relative standard error of 10 percent, as measured at the CGw value, after correcting for precision.

Analytical accuracy is expressed as the percent recovery of an analyte that has been added to the control samples at a known concentration prior to analysis or duplicate analysis of a gamma spectroscopy standard with a known amount of radioactivity.

The accuracy of data was summarized in terms of relative error (RE). This calculation reflects the degree to which the measured value agrees with the actual value, in terms of percent of the actual value. RE is calculated as:

There is no formal quantitative requirement for representativeness; representativeness is monitored by ensuring that sampling and analytical protocols are, in fact, carried out during field and laboratory work and that the quantity of data collected are sufficient to allow decision-making with the necessary level of confidence.

The data were collected in accordance with the FSP and the standard operating procedures (SOPs) contained in the FSP and the supporting plans and procedures. The data are considered representative of the field conditions and locations where they were collected.

3.1.4 Completeness Completeness is a measure of the degree to which the amount of sample data collected meets the scope and a measure of the relative number of analytical data points that meet the acceptance criteria, including accuracy, precision, and any other criteria required by the specific analytical method used. Completeness is defined as a comparison of the actual numbers of valid data points and expected numbers of points expressed as a percentage. The data completeness goal for the CSAP is 80 percent, consistent with the Phase 1 Final Status Survey Plan (FSSP).

Completeness is calculated after the quality control (QC) data have been evaluated, and the results applied to the measurement data. In addition to results identified as being outside of the April 2013 3-4

IUNCONTROLLED DOCUMENT I Radiological Characterization Report (RCR) (T04) - Rev. 0 QC limits established for the method, broken or spilled samples, or samples that could not be analyzed for any other reason, are included in the assessment of completeness. The percent of valid results is reported as completeness. The completeness will be calculated as follows:

Completeness (%) = T - (I + NC) X 100 T

Where:

T = Total number of expected measurements for a method and matrix, I = Number of invalidated results for a method and matrix, and NC = Number of results not collected (e.g., bottles broken, etc.) for a method and a matrix.

The percentage completeness is shown in Table 3-3. The completeness criterion of 80 percent was met for all analytes except carbon-14, iodine-129, and protactinium-231. The carbon-14 and protactinium-231 had data rejected during validation when there were negative results with an absolute value greater than the MDA. The iodine-129 data was rejected due to interference from bismuth-212 (SEC 2013b).

Comparability is a qualitative parameter expressing the confidence with which one data set can be compared with another. The comparability of the data, a relative measure, is influenced by sampling and analytical procedures. The data was collected with the specific April 2013 3-5

UNCONTROLLED DOCUMENTI Radiological Characterization Report (RCR) (T04) - Rev. 0 protocols in the FSP. The collection methods were in accordance with the CSAP; therefore, this data set and future data sets should be comparable regardless of who obtains the sample or performs the analysis.

3.2 Gamma Walkover Quality Assurance GWS QA included the following:

" Each detector was calibrated according to procedure SEC-RP-08, Workplace Monitoring.

" Instruments were set-up and checked according to procedure SEC-RP-52, Set-up and Operability Tests for Portable Field Instruments. This establishes reference readings and a plus or minus 20 percent acceptance range.

• Instruments were checked with a source of known radioactivity and for background according to procedure SEC-RP-53, Operability Tests - Field Instruments. Instruments all passed the specification that source and background checks fall within plus or minus 20 percent of their original set-up readings. The purpose of these measurements is to assure the instruments are functioning properly at the beginning of each day. Control charts were generated. Example source and background charts are provided in Appendix F.

• A 30-second measurement was made each day before use and at the end of the day at a reference location as specified in the FSP.

In addition to the measures listed above, each different detector was to be used to survey a I 00-m2 area established in Background Reference Area I. The purpose was to allow measurements made by different detectors of the same type (FIDLER or Nal) to be normalized, if needed. A tarp was then placed over the area to attain, over time, and maintain stable soil moisture content. Soil moisture may have an impact on the detector response. It is expected that the moisture content will equilibrate over the course of several weather seasons.

The FSP called for measurements on this 100-mi2 plot to be performed before putting a specific instrument used for performing GWS measurements in service. This was not possible, however, because approval to perform surveys on Background Reference Area I could not be immediately obtained at the start of the survey work. Approval of Background Reference Area 1 was obtained after the GWS was completed at the HLW Interim Storage Area. The survey of the 100-mi2 area was performed one week before demobilizing from the site. One of the FIDLER detectors malfunctioned. Other detectors required recalibration and were taken out of service. When the survey of the I 00-M 2 area was performed, two FIDLER and two Nal detectors were still in use.

The number of measurements, minimum, maximum, average, and standard deviation for each2 detector at the 100-m2 test plot are shown in Table 3-4. Now that approval for use of the 100-mi plot on Background Reference Area I has been established, future site survey work can begin with the survey of this plot.

A t-test showed that the mean count rate of the FIDLER and the NAI detectors were different with 99 percent confidence. The two FIDLER detectors exhibited a 552 cpm difference in the mean response. The Nal detectors exhibited a 709 cpm difference in the mean response. A way to normalize the detector response would have been to add 276 cpm to the response of one FIDLER and subtract 276 cpm from the response of the other FIDLER. Similarly, 355 cpm could be added to the response of one Nal detector and 354 cpm could be subtracted from the response of the other Nal detector.

This would have virtually no impact in the GWS data interpretation. The gamma radiation contours shown in Figures 2-1 and 2-2 are +/-2,000 cpm. Because the results of the two detector pairs shown in Table 3-4 is considered typical, normalization of detector response for the detectors used to survey the HLW Interim Storage Area would not have added value to the way the data was interpreted. The differences in the detector response are considered typical because detector crystals of the same media, size, and shape that are operated at their similar plateau voltages with photomultiplier tubes of a similar age will behave as the detectors shown in Table 3-4.

3.3 Data Verification and Validation Data verification was performed on 100% of the laboratory analytical data. Verification was performed to assure that samples sent for analysis were analyzed with results returned in hard copy and as an Electronic Data Deliverable (EDD). Verification of completeness for chain of custody records was performed. Verification that hard copy records from the laboratory matched the EDD was also completed. Errors found during verification were corrected.

Data deliverables meet U.S. Environmental Protection Agency (EPA) Level IV quality. Contract Laboratory Procedure (CLP)-like data packages were provided by the analytical laboratory to support independent third party validation. Ten percent of analyses were validated by an independent third party. The independent third party performed validation according to the U.S.

Department of Energy NNSA Service Center Model Data Validation Procedure(AQA 2010) and the applicable methods.

All data were used in computations (e.g., means of data sets) unless it was rejected by the validator. The data that were rejected are shown in Appendix C. Reasons for rejected data were:

0 Samples with a negative result with an absolute value greater than the minimum detectable concentration (MDC),

• 1-129 results where there was significant interference from a gamma photo-peak from naturally occurring Bi-212, and

• Samples where the chemical yield was less than 10 percent and with results less than the MDC.

IUNCONTROLLED DOCUMENT IUNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 APPENDIX D Borehole Gamma Logs April 2013

IUNCONTROLLED DOCUMENT UNCONTROLLED DOCUMENT Radiological Characterization Report (RCR) (T04) - Rev. 0 Appendix D Borehole Gamma Logs The borehole gamma logs were performed using a V2-inch by ]-inch Nal detector. The smaller detector was used so that it could fit into the borehole. Note that the smaller volume detector has a lower efficiency and a lower count rate response than the bigger Nal detectors used for the GWSs. Note also that the background count rate taken outside the borehole is less than that taken inside the borehole because, inside the borehole the detector is surrounded by the source of gamma radiation signal.

The borehole gamma logs were handwritten while work was performed. The borehole gamma logs shown in this appendix were typed for this report. The signed original forms are on file.

Detectors are taken out of service if the source or background checks are not within the required tolerance of 20 percent. If a detector does not pass the morning daily check, the data from the previous day is evaluated for use.

One FIDLER detector was taken out of service because it failed the background check above the upper tolerance. The detector was damaged and the failure was due to a light leak. The detector was not returned to service.
