Bus 10 Pad was originally an outdoor staging area designed to function as 'a decontamination facility. It was initially comprised of a concrete pad equipped with a drain system that emptied into the plant radwaste system. The pad was also used as a storage area for containers of radioactive spent primary resins and other contaminated items. In 1975, attempts to radiologically decontaminate the pad were unsuccessful.

Gamma spectrometry of dirt samples collected from the switchyard identified Co-60 and Cs-137. Loose contamination, was discovered under the switchyard fence.
Major demolition and remediation activities began in 2002. All radioactive systems and components located inside the SFB were removed and building structural surfaces were decontaminated to ensure contamination levels were acceptable for controlled demolition. Confirmatory radiological surveys were performed throughout the demolition process. The SFP liner was removed and the exposed concrete was decontaminated. The structural concrete of the SFP and the SFB was then demolished to grade. No above grade structures currently reside within Survey Unit 9312-0002.

The analysis of samples taken of the soils located along the northwest corner of the SFB between the SFB and Containment structure indicated the presence of significant concentrations of Cs-137, Co-60 and Sr-90.
Contamination was also identified in the soils to the south of the SFP as a result of SFB sump and cask wash-down pad leakage. In this area, a significant volume of contaminated soil that exhibited direct exposure rates was removed prior to commencing soil sampling for isotopic analysis. The soils in both of these areas were remediated to bedrock and the excavations were backfilled following the performance of radiological assessments. Soil remediation also occurred at the "Bus 10" area.

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.
DATA QUALITY OBJECTIVES (DQO)
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, 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.

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.

The DQO process determined that Cs-137, Co-60 and Sr-90 would be the radionuclides of concern in Survey Unit 9312-0002 (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 performance of this FSS would be evaluated to ensure adequate survey design.

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 Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 0.73 to achieve a relative shift (A/G) 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 MARSSIM in support of the decommissioning license termination rule (10CFR20, 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, three (3) judgmental samples were taken in this survey area. One (1) judgmental location was taken at the north quadrant of the survey unit in the vicinity of former Excavation 5, one (1) judgmental sample was taken in the southeast corner of the survey unit in the vicinity of the Bus 10 excavation and one (1) judgmental sample was taken in the southwest corner of the survey unit in the vicinity of former Excavation 3.
The resulting adjusted relative shift was 2.0.
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.

1.39E-02 1.1OE-02 1.21E-02 Cs-137 was positively detected in only two (2) of the samples collected for non-parametric statistical testing. This minimizes the usefulness of a statistical analysis of the data set. The range of the data is approximately four (4) standard deviations indicates a calculated skew of 0.46. 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 not positively identified in any 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.

The dose contribution from soil is 0.06 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.
The dose contribution from soil is 0.06 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) mrem/yr TEDE.
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) 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) mrem/yr 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 4.06 mremlyr TEDE. Therefore, Survey Unit 9312-0002 is acceptable for unrestricted release.

Revision 0 3

SPENT FUEL BUILDING (SFB)

(FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0002 RELEASE RECORD During plant operation, Survey Unit 9312-0002 was the location of significant, radiologically contaminated structures and systems, including the Spent Fuel Pool (SFP), the Spent Fuel Building (SFB), the "Bus 10" area and the northeastern quadrant of the 115kV Switchyard.

The Spent Fuel Building (SFB) was a concrete structure designed for the storage of new and spent fuel.

It contained radiologically contaminated items and process.

equipment necessary for safe handling and storage of spent nuclear fuel. The Spent Fuel Pool (SFP) itself was a thirty-six (36) ft long by thirty-seven (37) ft wide by thirty-five (35) ft deep pool located in the northern half of the SFB. The pool was filled with borated water and contained the spent fuel assemblies stored in racks.

Highly irradiated reactor components and other debris were stored in the pool as well.

Historical surveys of the building show that significant levels of fixed and loose contamination were present in this structure.

Bus 10 Pad was originally an outdoor staging area designed to function as 'a decontamination facility. It was initially comprised of a concrete pad equipped with a drain system that emptied into the plant radwaste system. The pad was also used as a storage area for containers of radioactive spent primary resins and other contaminated items. In 1975, attempts to radiologically decontaminate the pad were unsuccessful.

Subsequently, a layer a lead shielding was placed on top of the pad and a layer of concrete was poured over the lead. This pad eventually became the foundation for the Waste Compactor Building. In the late 1990s, the building was removed and the concrete pad and surrounding soils were remediated.

The 115 kV Switchyard (#111) was situated outside the RCA just south of the Containment building.

This area included two (2) Station Service Transformers

(# 204 & #205) and the 115 kV Tie Breaker (#218). Also, Bus 12 (#120) was located at the SW corner of the yard. There were several other transformers with associated power lines that extended beyond the switchyard area.

A review of the Historical Site Assessment and Supplement, as well as, other historical documents (e.g., the 10CFR50.75(g)(1) files) indicated a significant number of operational events have impacted Survey Unit 9312-0002. Operational events were considered to be 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.

Some of the major events are summarized as follows:

In October of 1976, a routine survey identified contaminated stones near the SFB concrete pad. The stones were removed and properly dispositioned as radioactive waste.

In June of 1977, a hot particle was discovered during a routine survey of the area adjacent to the 115 kV Switchyard. The contaminant was removed and a resurvey of the entire area as well as some equipment removed from the area indicated no remaining detectable activity.

SURVEY UNIT 9312-0002 RELEASE RECORD

  • In October of 1981, a survey identified loose surface contamination on the rails outside the SFB following a spill from the SFB lower level. The source or system where the spill originated was not identified.
  • In February of 1989, there was a release of radioactive liquid from the Spent Fuel Building drainpipe that resulted in distribution of plant related radioactivity to the drain trench located in the 115 kV Switchyard, the storm drain system components and soils at the storm drain outfall. Remediation of the plant related radioactivity associated with this event resulted in decontamination of the drain trench, the storm drain system and removal of a significant volume of soil.
  • During an annual survey performed in August of 1995, radioactive particles were found in and around the switchyard area. Some of the particles were embedded in the pavement around the switchyard.

Gamma spectrometry of dirt samples collected from the switchyard identified Co-60 and Cs-137. Loose contamination, was discovered under the switchyard fence.

The contaminated soil in the switchyard and portions of pavement were remediated.

In 1995, the track area near the SFB was contaminated during hydrolazing.

Major demolition and remediation activities began in 2002. All radioactive systems and components located inside the SFB were removed and building structural surfaces were decontaminated to ensure contamination levels were acceptable for controlled demolition. Confirmatory radiological surveys were performed throughout the demolition process. The SFP liner was removed and the exposed concrete was decontaminated.

The structural concrete of the SFP and the SFB was then demolished to grade. No above grade structures currently reside within Survey Unit 9312-0002.

Outside of the structures, considerable remediation was performed on the soils surrounding the SFP and SFB. The analysis of samples taken of the soils located along the northwest corner of the SFB between the SFB and Containment structure indicated the presence of significant concentrations of Cs-137, Co-60 and Sr-90.

Contamination was also identified in the soils to the south of the SFP as a result of SFB sump and cask wash-down pad leakage. In this area, a significant volume of contaminated soil that exhibited direct exposure rates was removed prior to commencing soil sampling for isotopic analysis. The soils in both of these areas were remediated to bedrock and the excavations were backfilled following the performance of radiological assessments.

Soil remediation also occurred at the "Bus 10" area.

Previous investigations had identified elevated levels of Cs-137 and Co-60 in the soils in this area.

Remediation was successful in this area prior to excavating to the beginning of the saturated zone or bedrock. As with other excavations, the area was backfilled following the performance of a radiological assessment.

In Survey Area 9312, post-remediation soil samples were taken from the as-left surface soils under two (2) Survey and Sampling Work Plans, SSWP-06-08-000 and SSWP-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.

SURVEY UNIT 9312-0002 RELEASE RECORD 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.

3.10E-01 2.76E-01 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.

Cs-137 0.689 Co-60 0.311 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.

SURVEY UNIT 9312-0002 RELEASE RECORD While Sr-90 was not identified in the soil characterization results, it was decided to include Sr-90 as 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, "Preparation of 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. 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 9312-0002 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.

SURVEY UNIT 9312-0002 RELEASE RECORD 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 =Hsoil + HExistingGW + HFutureGW 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) mrem/yr TEDE.

Equation 2 19 mrem/yrTotal = 15 mrem/yrsoil + 2 mrem/yrExisting Gw+ 2 mrem/yrrutureGW 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.

SURVEY UNIT 9312-0002 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 9312-0002 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 it's 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, "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 9312-0002 (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 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.

(FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0002 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 5.1-11 to 0.73 to achieve a relative shift (A/G) 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 MARSSIM in support of the decommissioning license termination rule (10CFR20, 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, three (3) judgmental samples were taken in this survey area.

One (1) judgmental location was taken at the north quadrant of the survey unit in the vicinity of former Excavation 5, one (1) judgmental sample was taken in the southeast corner of the survey unit in the vicinity of the Bus 10 excavation and one (1) judgmental sample was taken in the southwest corner of the survey unit in the vicinity of former Excavation 3.

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.

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 information pertaining to the FSS.

A single scan area was established that constituted approximately 100% of the surface area of Survey Unit 9312-0002. 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 8,390 counts per minute (cpm) up to 13,500 cpm.

SURVEY UNIT 9312-0002 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.

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."

Three (3) samples (9312-0002-003F, 9312-0002-004F and 9312-0002-015F) were randomly selected for HTD radionuclide analysis.

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 three (3) 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 two (2) of the fifteen (15) samples collected for non-parametric statistical testing. Co-60 was not positively identified in any 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. A summary of the fifteen (15) samples collected for non-parametric statistical testing results as well as the fraction of the DCGLOp is provided in Table 8.

SURVEY UNIT 9312-0002 RELEASE RECORD In addition to the non-parametric statistical sample population, three (3) 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.

No radionuclides of concern were positively identified in any of these samples.

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 Final Status Survey ".

Cs-137 was not detected in sufficient quantity in the field split results at location 9312-0002-005FS to evaluate in accordance with procedure. Evaluation using the reported results for naturally occurring K-40 resulted in acceptable agreement between the field-split results at this location.

The sample analysis vendor, General Engineering Laboratories, LLC, maintains quality control and quality assurance plans as part of normal operation.

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.

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 9.

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 not positively identified in any 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.

CONCLUSION Survey Unit 9312-0002 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.

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 0.06 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) 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) mrem/yr 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 4.06 mremlyr TEDE. Therefore, Survey Unit 9312-0002 is acceptable for unrestricted release.

Notes:

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 0

C Analyte has been confirmed by GC/MS analysis D

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 QC Samples were not spiked with this compound 86

Range Anist Date Time Y

A RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL h

Preparation or preservation holding time was exceeded 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.

Description:

Comparison of split samples collected from sample measurement location Y5 and analyzed using gamma spectroscopy by off-site Vendor Laboratory. The standard sample was 9312-0002-0051F, the comparison sample was 9312-0002-0051FS.

STANDARD COMPARISON Radionuclide Activity Standard Resolution Agreement Activity Standard Comparison Acceptable Value Error Range Value Error Ratio (Y/N)

K-40 1.19E+01 0.570 21 0.75-1.33 1.12E+01 0.505 0.94 Y

Comments/Corrective Actions: Cs-137 was not detected in sufficient quantities in the field split results at location 9312-0002-005F to evaluate in accordance with procedure. Evaluation using the reported results for K-40 resulted in acceptable agreement between the field-split results at these locations.. Since K-40 was found to be present at an acceptable level of agreement, no further action is warranted.

Table is provided to show acceptance criteria used to assess split samples.
