The survey unit is bounded as follows: land Survey Unit 9312-0009 to the north (called north as oriented with the north to south flow of the Connecticut River), land Survey Units 9312-0009 and 9527-0005 to the east, land Survey Units 9522-0007 to the south, and land Survey Unit 93 12-0002 and 93 12-0007 to the west. The survey unit is located along the east boundary of Survey Area 9312. It is comprised of flat gravel terrain. The eastern boundary is bordered by a steep rock cliff that transitions to a steep soil bank from north to south.The reference coordinates associated with this survey unit are E013 through E014 by S067 through S071 (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 "Classijfication Basis Summary" conducted for Survey Unit 9312-0010 consisted of: a) A review of the 1OCFR5O.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 Characterization Reports " as well as the previous "Classification Basis 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.During plant operation, Survey Unit 9312-0010 was a part of the radiological controlled area and the location of significant, radiologically contaminated structures and systems. Structures included the yard crane, primary water Revision 0 3 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD storage tank and backup primary water storage tank.Major demolition and remediation activities began in 2002. All radioactive 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. The dose from residual radioactivity on the remaining steel and concrete in the sump was accounted for in the "Basement Fill Model". The Incore Sump was then 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 clean soil to the grade of the exterior open land. The above grade portion of the Contairnment structure was then demolished and removed. Confirmatory radiological surveys were performed throughout the demolition process. No above grade structures currently reside within Survey Area 9312.Outside of the containment shell, soil remediation began 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. 1.This excavation included the area in the vicinity of the Refueling Water Storage Tank and the Primary Auxillary Building (PAB) corrider.

A second large excavation, also designated as Excavation

1. 2 was located over the Service Building footprint.

A third excavation, designated as Excavation

1. 3 was located in the area between the Containment Building and Spent Fuel Building (SFB).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 footing and miscellaneous fragments of footings and slabs on the bedrock. As with the Containment basement shell, all excavations were backfilled with clean fill following the performance of a radiological assessment.

This report represents the second of two (2) attempts to FSS this survey unit. An initial FSS survey was performed starting on 0 1-22-07. Subsequent to the completion of this FSS Survey, but prior to the submittal of its Release Record, a remediation campaign was performed on the steep hillside in adjacent survey unit 9312-0009.

The remediation efforts were followed by heavy rains that washed a portion of the hill side soils into the portion of the eastern end of this survey unit.A surveillance of the affected area was performed on 03-15-07.

Four (4) biased samples were collected at the location of the highest observed scan readings.RevisionO0 4

NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD Two (2) of the four (4) samples had on-site sample results in excess of the DCGL, primarily due to the presence of Cs-137, which was determined to be present at concentrations up to 7 pCi/g.A remediation was performed over the affected area, the remediation survey results indicated that the area was cleaned to levels below the DCGL.Table 1 -Basic Statistical Quantities for Cs-137, Co-60 and Sr-90 from the Initial Final Status Survey & Surveillance Soil Sample Population Cs-137 Co-60 Sr-90 (Pci/g) 00/0lg (Pcilg)Minimum Value: -6.60E-03

6.52E-0 I 3.43E-02 2.78E-0 I A review of this sample data shows Cs-137, Co-60 and Sr-90 to be the primary radionuclides of concern, with both Cs-137 and Co-60 reported at fairly low concentrations.

Sr-90 was the predominant nuclide primarily due to one scan investigation sample result from the initial FSS (sample 9312-0010-0161).

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.Revision 05 5 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD Table 2 -Distribution Fraction for Detectable Radionuclides in Soil Sample Population Detected Radionuclide Distribution Fraction Cs-137 0.408 Co-60 0.047 Sr-90 0.545 No additional 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.

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, "Preparation of Final Status Survey P/an, " and the "Mu/ti-Agency Radiation Survey and Site Investigation Manual" (MARS SIM). 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.

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, Revision 06 6 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD 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 9312-0010 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 HTotal=Hs 0 oii+HExistingGw

+/-HFutureGW The total dose under the LTP criteria is twenty-five (25) mremlyr 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) mremlyr 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.Equation 2 19 mrem/yrT 0 t,, = 15 mremlyrs 1 il + 2 mnreM/YrExisting GW+ 2 mremn/yrhFtureGW Revision 07 7 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD The allowable dose for soil in this survey unit is fifteen (15) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in fifteen (15) mrem/yr TEDE is designated as the Operational DCGL (DCGLOp), and has been established for the radionuclides of concern as provided in Table 3.Revision 08 8 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD Table 3 -Radionuclide Specific Base Case Soil DCGLs, Operational DCGLs and Required Minimum Detectable Concentrations (MDCs)Radionuclide

The preferred result is the alpha spectroscopy's when both analyses are performed Revision 09 9 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 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 9312-0010 for FSS.Cs-137, Co-60 and Sr-90 were the three (3) radionuclides reported in concentrations with the potential for exceeding the release criteria.

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, "Preparation of Final Status 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 determined that Cs-137, Co-60 and Sr-90 would be the radionuclides of concern in Survey Unit 9312-0010 (refer to Section 3). The characterization surveys did not include any 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 performance 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.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 Revision 0 10 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD Final Status Survey." The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5. 1-11 to 0. 5 to achieve a relative shift (A/oY) in the range of 1 and 3. The resulting relative shift was 1.5. 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 MARSSIM in support of the decommissioning license termination rule (lOCFR2O, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design. The survey design specified eighteen (18) surface soil samples for non-parametric statistical testing. Based upon a review of the historical information and Characterization Survey data, the acquisition of five (5) judgmental surface soil samples from two (2) areas within this survey unit was deemed appropriate.

These two (2) areas included where the remediation was performed and the sample location that indicated an elevated Sr-90 concentration, based on the initial FSS sample results.The grid pattern and locations of the soil samples were determined 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.Table 4 -Sample Measurement Locations with Associated GPS Coordinates Designation Northing Easting 9312-0010-IOIF 236722.97 668813.41 9312-0010-102F 236696.79 668858.76 9312-0010-103F 236670.61 668904.10 9312-0010-104F 236670.61 668934.33 93 12-0010-105F 236670.61 668964.55 93 12-0010-106F 236644.43 668919.21 93 12-0010-107F 236644.43 668949.44 9312-0010-1 08F 236644.43 668979.67 Revision 0 1 I I NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD Table 4 -(continued)

Two (2) soil samples, or about 10% of the number of samples that would be used for non-parametric statistical testing were randomly selected for HTD radionuclide analysis using the Microsoft Excel "RAND" function.

Each sample was sent off-site for a full suite analysis of the HTD radionuclides specified in the LIP, Table 2-12, "Radionuclides Potentially Present at Haddam Neck P/ant" 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 "RAND" function.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.

SURVEY IMPLEMENTATION Final status survey field activities were conducted under the Final Status Survey Plan (FSSP). The FSSP contained a 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 information pertaining to the FSS.A single scan area was established that constituted approximately 100% of the surface area of Survey Unit 93 12-0010. 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 8,240 counts per minute (cpm) up to 14,000 cpm.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 Revision 0 1 13 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD 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.Measurement 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.Eighteen (18) 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 (9312-0010-1 02F and 9312-00 10-111 IF) were randomly selected for HTD radionuclide analysis.The implementation of survey specific quality control measures included the collection of one (1) sample (93 12-0010-1 14F) for "split sample" analysis.6. SURVEY RESULTS All field survey activities were conducted from March 26, 2007 to March 29, 2007.The sample locations identified in the FSS plan were scanned over approximately a one (1) meter radius for elevated radiation levels. Table 5 provides an overview of the scan results for sample measurement locations.

The laboratory analyzed the eighteen (18) samples collected for non-parametric statistical testing, the associated field splits 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 concentrations exceeding the de-selection criteria.Cs-137 was identified in twelve (12), Co-60 was identified in one (1) and Sr-90 in two (2) of the eighteen (18) samples collected for non-parametric statistical testing. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels higher than expected environmental levels for Cs- 137 within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide Revision 0 18 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD and the measurement method. All analyses performed met the required minimum MDC. In one (1) sample, C-14 was detected at two (2) percent of the DCGL which is below the selection criteria discussed in Section 2. No additional HTD radionuclides were positively identified (i.e., a result greater than two (2) standard deviations uncertainty).

The "sum-of-fractions"~

or "unity rule." is the mathematical test used to evaluate compliance with radiological criteria for license termination 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). The unity rule is: Equation 3 Cl- C 2 Cn DCGL, DCGL 2 DCGL, Where: Cn = concentration of radionuclide n and DCGLn DCGL of radionuclide n.The results of the unity rule calculation for the radionuclides of concern in the statistical sample population for Survey Unit 9312-0010 are provided in Table 9 below.Table 9 -Results of Unity Calculation for Surface Comprising the Statistical Sample Population Soil Samples Sample Number Fraction of the Operational DCGL1' )(2) unity___________

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 Final Status Survey ". There was acceptable agreement between the field split results.The sample analysis vendor, General Engineering Laboratories, LLC, maintains quality control and quality assurance plans as part of normal operation.

Refer to Attachments 3 and 4 for data and data quality analysis results 8. IN4VESTIGATIONS AND RESULTS Three (3) investigative samples were collected from locations exhibiting elevated scan measurements and (5) judgmental samples were taken from the survey area.Four (4) of the judgmental samples were taken from the vicinity of the area that was subjected to remediation.

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 with "clean" fill 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 Final Status Survey Plan.Revision 0 2 21 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD 1. 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.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 11.Table 11 -Basic Statistical Quantities for Cs-137, Co-60 and Sr-90 from the Final Status Survey Cs-137 Co-60 Sr-90 pCi/g pCi/g pCi/g DCGL,,p: 4.75 2.29 0.93 Minimum Value: -2.35E-02

The difference between the mean and median was about 40% to 60% of the standard deviation which indicates some skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot indicates a slight to diminishing skewness as confirmed by the calculated skew of 2.13, 0.58 and 0.26 for Cs-137, Co-60 and Sr-90 respectively.

Revision 0 2 22 NORTHEAST PROTECTED AREA GROUNDS SURVEY UNIT 93 12-0010 RELEASE RECORD All data, assessments, and graphical representations are provided in Attachment 4.12. ANOMALIES No anomalies were noted in the performance of this Final Status Survey.13. CONCLUSION Survey Unit 93 12-0010 has met the final DQOs of the FSS plan. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.All 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 1.2 mrem/yr 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) mremlyr 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 5.2 mremlyr TEDE. Therefore, Survey Unit 9312-0010 is acceptable for unrestricted release 14.
