SURVEY UNIT 93 12-0001 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9312-0001 (Containment) is designated as Final Status Survey (ESS)

Class 1 and consists of approximately one thousand nine hundred-seventy five (1,975) square meters of open land and is located approximately one thousand four hundred eighty feet (1,480 ft) to the southeast of the site benchmark (Northing:

237370.20, Easting: 667394.57) site reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see Attachment 1). The survey unit is bounded as follows: land Survey Unit 93 12-0005 and land Survey Unit 93 12-0006 to the north (called north as oriented with the north to south flow of the Connecticut River), land Survey Unit 9312-0003 to the west and south and land Survey Unit 9312-0002 to the east and south. As a result of demolition and remediation activities, the area topography is mostly flat and de-vegetated. The survey unit has a moderate slope running from east to west.

The reference coordinates associated with this survey unit are E009 through E0 12 by S067 through S069 (refer to "HNP License Termination Plan" (LTP) Section 5.4.4).

The reference coordinates provide the maximum dimensions of a rectangle containing this survey unit. Some areas contained in this rectangle may not be part of this survey unit. The boundary of the survey unit was defined using a Global Positioning System (GPS) based on the Connecticut State Plane System North American Datum (NAD) 1927.

2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5. 1-10, "Survey Unit Classification."

The "ClassificationBasis Summary" conducted for Survey Unit 93 12-0001 consisted of:

a) A review of the 10CFR5O.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historic Site Assessment Supplement, "

c) Historic and current survey records review, d) Visual inspections and a "walkdown."

A review of the "Initial and Supplemental CharacterizationReports" as well as the previous "ClassificationBasis Summaries" was performed. The source documents, the "Connecticut Yankee Haddam Neck Characterization Report" and "Initial Classification for Survey Areas at Connecticut Yankee", were incorporated by reference in LTP, Revision 0.

CONTAINMENT (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 93 12-0001 RELEASE RECORD During plant operation, Survey Unit 9312-0001 was the location of significant, radiologically contaminated structures and systems, namely the reactor, the reactor systems and the Containment structure.

The Containment Building housed the reactor, reactor primary systems and components as well as numerous other support systems. With the exception of various service water, gas and air systems, the majority of the systems within the Containment were radiologically contaminated. Radioactive material concentrations in many of these components and systems were high enough to create high radiation areas in their vicinity. The entire Containment Building interior was posted as a "Contaminated Area". Hi storical surveys of the building show that significant levels of fixed and loose contamination were present in this structure. Some components, equipment, structural steel and concrete became radioactive due to neutron activation.

A review of the Historical Site Assessment and Supplement, as well as, other historical documents (e.g., the IOCFR5O.75(g)(l) files) indicated a significant number of operational events have impacted Survey Unit 9312-0001. These events included significant spills and leakage from contaminated systems. These events would have had the most impact on the radiological condition of subsurface structures and footers; and the underlying soil and bedrock prior to system and structural decontamination and demolition.

Major demolition and remediation activities began in 2002. All contaminated systems and components located inside the Containment Building, including the reactor vessel, were removed and appropriately packaged and shipped to an approved off-site disposal facility. Interior structural surfaces inside the Containment Building were decontaminated to ensure contamination levels were acceptable for controlled demolition, Interior walls and floors were then demolished and removed. The Containment liner was removed with the exception of the Incore Sump, which was filled with grout to the basement floor elevation. The remaining interior surfaces inside the Containment shell were decontaminated.

Following decontamination, the Containment basement was filled with soil to the grade of the exterior open land. The above grade portion of the Containment structure was then demolished and removed. Fill was then placed over the survey unit, raising the grade of the area by approximately four (4) feet. No above grade structures currently remain within Survey Unit 93 12-000 1.

Outside of the structures, considerable remediation was performed on the soils surrounding the Containment structure, particularly around the northeast, northwest and southeast quadrants of the survey unit. A large excavation was created to the north of the Containment that was designated as Excavation #1. This excavation included the area in the vicinity of the Refueling Waster Storage Tank and the Primary Auxiliary Building (PAB) corridor. A second large excavation, designated as Excavation #2 was located over the Primary Auxiliary Building (PAB) footprint.

A third excavation, designated as Excavation #3 was located in the area between the Containment Building and Spent Fuel Building (SFB).

CONTAINMENT (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 93 12-0001 RELEASE RECORD As adjacent structures were demolished, soil was excavated and removed. This process continued until bedrock was exposed. Subsurface structures and footings that remained following demolition and excavation include the Containment Mat, the Cable Vault wall, the Service Building east wall, a remnant of the PAB northwest wall, Waste Disposal Building (WDB) footing and miscellaneous fragments of footings and slabs on the bedrock. As with the Containment basement shell, all excavations were backfilled following the performance of radiological assessments.

In Survey Area 9312, post-remediation soil samples were taken from the as-left surface soils under two (2) Survey and Sampling Work Plans, SSWVP-06-08-000 and SSWPT-06-12-001. Thirty-five (35) post remediation surface soil samples were collected from the various locations within Survey Area 9312. All samples were collected and analyzed by gamma spectroscopy by an approved off-site laboratory.

Ten (10) of the thirty-five (35) post remediation samples collected were analyzed for the full suite of "Hard-to-Detect" (HTD) radionuclides specified in the LTP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant" and as provided in Table 3. Statistical quantities (mean, median and standard deviation) from the 2006 post-remediation survey conducted under SSWP-06-08-000 and SSWP-06-12-001 are provided in Table 1.

Minimum Value: 1.32E-02 -5 .OOE-02 Maximum Value: 1.70E+00 1.43E+/-00 Mean: 2.3 8E-0lI 1.08E-01 Median: 1.65E-01 1.46E-02 Standard Deviation: T3. 1OE-0 I 2.76E-0lI A review of this sample data shows Cs-137 and Co-60 to be the primary radionuclides of concern, with both isotopes reported at fairly low concentrations.

The sample population as a whole was evaluated to assess the distribution of the detected radionuclides. The radionuclide distribution percentage for each sample in the population was calculated by dividing the concentration of each detected radionuclide by the total activity concentration in the sample, expressing the abundance of the specific nuclide in the sample compared against the total activity.

The mean radionuclide distribution was then calculated by taking the average of the individual sample distribution fractions. The results are provided in Table 2.

SURVEY UNIT 93 12-0001 RELEASE RECORD Cs-137 0.689 Co-60 0.3 11 No HTD radionuclides were positively identified in concentrations meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty). Radionuclide screening or de-selection is a process where an individual radionuclide or aggregates may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates.

While Sr-90 was not identified in the soil characterization results, it was decided to include Sr-90 is a radionuclide of concern for this survey unit as Sr-90 was prevalent in the soils prior to remediation. Therefore, all volumetric soil samples taken as part of the survey design for this survey unit were subjected to direct analysis for Sr-90.

The FSS Engineer performed a visual inspection and walk-down during March 2007 to assess the physical condition of the survey unit, evaluate access points, travel paths and identify potentially hazardous conditions.

This survey area is affected by existing and future groundwater (reference CY memo ISC 06-024) which will be a source of dose from residual radioactivity, as discussed in Section 3 under the Data Quality Objectives.

Based upon the identification of radioactive material above the Derived Concentration Guideline Levels (DCGLs), and the need for radiological remediation, it was concluded that there was some probability for residual radioactivity in concentrations greater than the DCGLs, justifying a final survey unit classification of Class 1 (refer to Section 3).

3. DATA QUALITY OBJECTIVES (DQO)

FSS design and planning used the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5. 1-11, "Preparationof Final Status Survey Plan," and the "Multi-Agency Radiation Survey and Site Investigation Manual" (MARSSIM). A summary of the main features of the DQO process are provided herein.

The DQO process incorporated hypothesis testing and probabilistic sampling distributions to control decision errors during data analysis. Hypothesis testing is a process based on the scientific method that compares a baseline condition to an alternate condition. The baseline condition is technically known as the null hypothesis.

Revision 06 6

CONTAINMENT (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 93 12-0001 RELEASE RECORD Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided for rejection. In designing the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria. Rejection of the null hypothesis would indicate that residual activity within the survey unit does not exceed the release criteria.

The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9312-0001 did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).

A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity. This is done through the development of DCGLs. The DCGLs represent average levels of radioactivity above background levels and are presented in terms of surface or mass activity concentrations.

Chapter 6 of the LTP describes in detail the modeling used to develop the DCGLs for soil (called Base Case Soil DCGL), existing groundwater radioactivity and future groundwater radioactivity that will be contributed by building basements and footings.

The DCGLs presented in Chapter 6 of the LTP were developed for exposures from three (3) components, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity.

Equation 1 shows the mathematical relationship between the three (3) components and the total dose.

Equation 1 Hiotai -H Soil +/-HExistingGW +/-H FutureGW The total dose under the LTP criteria is twenty-five (25) mrem/yr Total Effective Dose Equivalent (TEDE) from all three (3) components. The allowable total dose under the Connecticut Department of Environmental Protection (CTDEP) radiological remediation standard for CY is nineteen (19) mrem/yr TEDE. To satisfy both the LTP and CY CTDEP criteria, the dose from soil must be reduced when using the existing and future groundwater dose values discussed above.

This survey area is affected by existing groundwater (reference CY memo ISC 06-024). Therefore, the dose contribution from existing groundwater is bounded by two (2) mrem/yr TEDE.

This survey unit is considered impacted by future groundwater radioactive contamination, as there are underground foundations containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contribution from future groundwater, the third dose component, is bounded by two (2) mremlyr TEDE.

CONTAINMENT (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 93 12-0001 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability. Soil samples were collected in 2006 to establish the radiological condition of Survey Unit 9312-0001 for FSS.

Cs-137 and Co-60 were the two (2) gamma emitting radionuclides reported in concentrations with the potential for exceeding the release criteria. Sr-90 was included as a radionuclide of concern due to its prevalence in the soil prior to remediation. The characterization data were used for the survey design and are provided in Table 1.

Instrument DQOs included a verification of the ability of the survey instrument to detect the radiation(s) of interest relative to the DCGL. Survey instrument response checks were required prior to issue and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data.

As, part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. Results reported as less than Minimum Detectable Concentration (MDC) were not accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result, and uncertainty to two (2) standard deviations, laboratory data qualifiers, units, and the required and observed MDC.

4. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. Guidance for preparing FSS plans is provided in Procedure RPM 5.1-11, "Preparationof FinalStatus Survey Plans". The FSS plan uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.

The DQO process determnined that Cs-137, Co-60 and Sr-90 would be the radionuclides of concern in Survey Unit 93 12-0001 (refer to Section 3). The characterization survey did not include any other additional HTD radionuclides of concern for this survey unit. As Sr-90 concentrations were determined by direct analysis, surrogate DCGLs were not required as part of the survey design for this survey unit via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". Other radionuclides that were positively identified in concentrations greater than the screening criteria during the performnance of this FSS would be evaluated to ensure adequate survey design.

As the survey unit is classified as a Class 1 surface soils area, and discrete, elevated areas of contamination was possible, the application of the Elevated Measurement Comparison (EMC) remained an option.

The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation. This approach was conservative since it included background Cs- 137 as part of the sample set.

SURVEY UNIT 93 12-0001 RELEASE RECORD The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Surface Samples for Final Status Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5. 1-11ito 0.73 to achieve a relative shift (A/cy) in the range of 1 and 3.

The resulting adjusted relative shift was 2.0. A Prospective Power Curve was generated using COMPASS, a software package developed under the sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of the MARS SIM in support of the decommissioning license termination rule (IOCFR2O, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design. The survey design specified. fifteen (15) surface soil samples for non-parametric statistical testing. Based upon a review of the historical information and Characterization Survey data, four (4) judgmental samples were taken in this survey area. One (1) judgmental sample was taken at the northeast corner of the survey unit in the vicinity of the "Tank Farm" excavation; two (2) judgmental samples were taken in the southeast corner of the survey unit in the vicinity of the Fuel Transfer Tube excavation and the Spent Fuel Building foundation and one (1) judgmental sample was taken in the northwest quadrant in the vicinity of the Primary Auxiliary Building excavation.

The grid pattern and locations of the soil samples were determnined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status Survey." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 1 area.

Sample locations were identified using AutoCAD-LT, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 4.

Each sample was sent off-site for a full suite analysis of the HTD radionuclides specified in the LTP, Table 2-12, "RadionuclidesPotentially Present at Haddam Neck Plant" and as provided in Table 3.

The LTP requires a minimum of 5% of the samples taken for non-parametric statistical testing be selected for QC evaluation. The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey," included the collection of one (1) soil sample for "split sample" analysis by the off-site laboratory. This location was selected randomly using the Microsoft Excel "RANDBETWEEN" fuinction.

The LTP specifies a required scanning coverage of 100% for outdoor Class 1 areas.

For this Class 1 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8. Table 5 provides a synopsis of the survey design.

5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under a Final Status Survey Plan (FSSP). The FSSP package included a detailed survey plan, job safety analysis, job planning checklist and related procedures for reference. Daily briefings were conducted to discuss the expectations for job performance and the safety aspects of the survey. The "Daily Survey Journal" was used to document field activities and other inform-ation pertaining to the FSS.

A single scan area was established that constituted approximately 100% of the surface area of Survey Unit 9312-0001. Grid lines, one (1) meter wide, were painted on the ground of the scan area. A background survey was performed around the survey unit and it was determined that, using an Eberline E-600 with a SPA-3 sodium iodide detector, background ranged from 7,170 counts per minute (cpm) up to 13,200 cpm.

SURVEY UNIT 9312-0001 RELEASE RECORD The scan area was established and scanned for elevated readings (see Attachment 2 for all scan results). Scanning was performed with an Eberline E-600 using a SPA-3 sodium iodide detector. The E-600 was operated in the rate-meter mode and used with audio response. The probe was positioned as close to the ground as possible and was moved at a scan speed of about 0.5 meters per second. Approximately 100% of the survey unit was scanned.

Meastfr ement locations were identified* in North American Datum (NAD) 1927 coordinates using GPS coordinates; sample locations were identified and marked with a surveyor's flag or paint for identification. At each sample location, a one (1) meter radius circle was established around the sample flag or paint mark was scanned for elevated radiation levels.

Nineteen (19) surface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Media for Final Status Survey" and FSS design. Samples were controlled, transported, stored, and transferred to the off-site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples."

Two (2) samples (93 12-0001-005F and 9312-0001-015F) were randomly selected for HTD radionuclide analysis.

The implementation of survey specific quality control measures included the collection of one (1) sample (9312-0001-003F) for "split sample" analysis.

6. SURVEY RESULTS All field survey activities were conducted between March 24, 2007 and March 26, 2007.

The sample locations identified in the FSS plan were scanned over approximately a one (1) meter radius for elevated radiation levels. Table 6 provides an overview of the scan results for sample measurement locations. Scan results are provided in Attachment 2.

The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC. The laboratory analyzed the fifteen (15) samples collected for non-parametric statistical testing, the associated field splits and the four (4) judgmental samples using gamma spectroscopy. Gamma spectroscopy analysis was performed to the required MDCs. Gamma spectroscopy results identified some radionuclides meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty). However, Cs-137 was the only gamma-emitting radionuclide reported in any appreciable concentration.

Cs-137 was positively identified in six (6) of the fifteen (15) samples collected for non-parametric statistical testing. Co-60 was positively identified in one (1) sample from the statistical sample population. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels at or below expected environmental levels for Cs-137 within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063.

The "sum-of-fractions" or "unity rule" is the mathematical test used to evaluate compliance with radiological criteria for license termnination when more than one radionuclide has been determined to be potentially present. The combination of the fractions of each detected radionuclide against their respective Operational DCGL must be less than or equal to one (1).

SURVEY UNIT 93 12-0001 RELEASE RECORD In addition to the non-parametric statistical sample population, four (4) judgmental surface soil samples were taken at biased locations. These locations were selected by the FSS Engineer based upon a review of the historical site assessment for this area and previous survey results. These judgmental soil samples were analyzed for Cs- 137, Co-60 and Sr-90 in accordance with the DQOs used during the survey design.

A summary of the four (4) judgmental samples collected as well as the results of the unity rule calculation for the identified radionuclides are provided in Table 9.

(3) B = biased - indicates judgmental sample location In addition to Cs-137 and Co-60, Sr-90 was also identified during the DQO process as a radionuclide of concern. Subsequently, all samples were subjected to analysis by gas proportional counting for Sr-90. All analyses met the required minimum MDC.

Sr-90 was not positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in any of the fifteen (15) samples collected for non-parametric statistical testing nor in any of the judgmental soil samples. In addition to Sr-90, the off-site laboratory also processed, as required by the sample plan, two (2) samples for the full suite of HTD radionuclides as specified in LTP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck Plant" and as provided in Table 3. The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses performed met the required minimum MDC. No other HTD radionuclides were positively identified.

7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. One sample location was selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for FinalStatus Survey ".

Gamma spectroscopy results identified some radionuclides meeting the accepted criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty). However, no gamma emitting radionuclide was reported in any concentration greater than its respective MDC.

9. REMEDIATION AND RESULTS Radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to FSS. All excavations were characterized and backfilled prior to performing FSS. In the area where remediation occurred, the ground area is comprised of barren dirt with no vegetation, and the soils have been graded relatively flat to the corresponding elevation of the adjacent survey units. The results for Cs-137 following remediation were well below the Operational DCGL provided in Table 3. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in soil was ALARA.

10. CHANGES FROM THE FINAL STATUS SURVEY PLAN No changes were made to the FSS plan.

11. DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessment, " for completeness and consistency. The sampling design had adequate power as indicated by the Retrospective Power Curve. The Sign Test was performed on the data and compared to the original assumptions of the DQOs. The evaluation of the Sign Test results demonstrates that the survey unit passes the unrestricted release criteria, thus, the null hypothesis is rejected.

SURVEY UNIT 9312-0001 RELEASE RECORD Documentation was complete and legible. Surveys and sample collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class 1.

The preliminary data review consisted of calculating basic statistical quantities (e.g.,

mean, median, standard deviation). The mean and median values are well below the Operational DCGL. Also, the retrospective power curve shows that a sufficient number of samples were cOllected to achieve the desired power. Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs. The basic statistical quantities for the statistical sample population are provided below in Table 9.

DCGLoP: 4.75E+/-00 2.29E+/-00 9.30E-01 Minimum Value: -2.03E-02 -4.50E-03 -3.49E-02 Maximum Value: 7.99E-02 2.57E-02 2.82E-02 Mean: 2.15E-02 5.43E-03 -3.5 1E-03 Median: 1.20E-02 2.14E-03 -7.40E-04 Standard Deviation: 3.28E-02 9.40E-03 1.44E-02 Cs-137 was positively detected in six (6) of the samples collected for non-parametric statistical testing. The range of the data is less than one (1) standard deviation and the data set exhibits a calculated positive skew of 0.74. The Cs-137 results are represented graphically through posting plots, a frequency plot, and a quantile plot.

Co-60 and Sr-90, although included in the FSS plan for compliance purposes, was positively identified in only one (1) of the fifteen (15) samples collected for non-parametric statistical testing. Assessment of the basic statistical quantities and graphical representation of Co-60 and Sr-90 was not considered useful given the non-existent number of actual data points to represent the distribution.

All data, assessments, and graphical representations are provided in Attachment 4.

12. ANOMALIES No anomalies were noted.

13. CONCLUSION Survey Unit 9312-0001 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved. Elevated Measurement Comparison was not required.

CONTAINMENT (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 93 12-0001 RELEASE RECORD All positively identified radionuclides of concern were used for statistical testing to determine the adequacy of the survey unit for FSS.

The sample data passed the Sign Test. The null hypothesis was rejected. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. The survey unit is properly designated as Class 1.

The dose contribution from soil is 0.10 mremlyr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.

This survey area is affected by existing groundwater (reference CY memo ISC 06-024); therefore the dose contribution from existing groundwater is bounded at two (2) mrem/yr TEDE.

This survey unit is considered impacted by future groundwater radioactive contamination, as there are underground foundations containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contribution from future groundwater, the third dose component, is bounded by two (2) mremlyr TEDE.

The average total dose from residual radioactivity in this survey unit, including exposures from the three (3) components as described in Section 3, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity will not exceed 4.10 mremlyr TEDE. Therefore, Survey Unit 9312-0001 is acceptable for unrestricted release.

Data Review Qualifier Definitions Page 12 of 110

Data Review Qualifier Definitions Qualifier Explanation

• A quality control analyte recovery is outside of specified acceptance criteria

• • Analyte is a surrogate compound

• Result is less than value reported

• Result is greater than value reported RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL A The TIC is a suspected aldol-condensation product

• Target analyte was detected in the associated blank B Metals-Either presence of analyte detected in the associated blank, or MDL/IDL < sample value < PQL BD Results are either below the MDC or tracer recovery is low C Analyte has been confirmed by GC/MS analysis D Results are reported from a diluted aliquot of the sample d 5-day SOD-The 2:1 depletion requirement was not met for this sample E Organics-Concentration of the target analyte exceeds the instrument calibration range E Metals-%difference of sample and SD is >10%. Sample concentration must meet flagging criteria H Analytical holding time was exceeded h Preparation or preservation holding time was exceeded J Value is estimated N Metals-The Matrix spike sample recovery is not within specified control limits N Organics-Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC) . Quantitation is based on nearest internal standard response factor N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Analyte concentration is not detected above the reporting limit UT Gamma Spectroscopy-Uncertain identification X Consult Case Narrative, Date Summary package, or Project Manager concerning this qualifier Y QC Samples were not spiked with this compound Z Paint Filter Test-Particulates passed through the filter, however no free liquids were observed.

The Qualifiers in this report are defined as follows:

• • Analyte is a surrogate compound

• Result is less than value reported

• Result is greater than value reported A The TIC is a suspected aldol-condensation product B For General Chemistry and Organic analysis the target analyte was detected in the associated blank.

BD Results are either below the MDC or tracer recovery is low C Analyte has been confirmed by GC/MS analysis

• Results are reported from a diluted aliquot of the sample H Analytical holding time was exceeded J Value is estimated N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Analyte concentration is not detected above the detection limit R Sample results are rejected U Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.

UI Gamma Spectroscopy~-Uncertain identification X Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y QC Samples were not spiked with this compound A RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL h Preparation or preservation holding time was exceeded Page 109 of 10

GEL LABORATORIES LLC 2040 Savage Road Charleston SC 29407 - (843) 556-8171 - www.gel .com QC Summary Workorder: 183245 Page 13 of 13 Parmname NOM Sample Qual ~QC Units RPD% REC% Range Anlst Date Time N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.

• • Indicates analyte is a surrogate compound.

A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.
