The PAB was a concrete structure designed to house systems containing radioactive materials. The building was designed to contain and control leakage occurring during routine operations as well as unusual conditions. With the exception of various service water, gas and air systems, the majority of the systems within the PAB were radiologically contaminated. The PAB also contained highly contaminated pipe trenches and pump pit areas. The lower level of the PAB under the boron recovery equipment was contaminated due to past spills involving evaporator bottoms.

The DWST and CST were also designated as Tank "TK-25-lA" and Tank "TK IB" respectively. The DWST and the CST was 'located to the southwest of the Containment Building in the northwest corner of the 115 kV Switchyard. Even though these tanks were designed to normally contain only non-radioactive water, there was a documented history of radiologically contaminated water occasionally being introduced into these systems. Events that may have contributed to the introduction of contaminated water into these tanks were steam generator tube failures and misalignment of valves. Historical surveys performed in the vicinity of these tanks did not indicate any significant levels of radioactive contamination. During April 1999, a shallow monitoring well and a deep monitoring well on the west side of the DWST produced samples that showed positive results for tritium.
In addition, 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A review of the Historical Site Assessment and Supplement, as well as, other historical documents (e.g., the 10CFR50.75(g)(1) files) indicated a significant number of operational events have impacted Survey Unit 9312-0003. 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;
The DWST and CST were also designated as Tank "TK-25-lA" and Tank "TK IB" respectively.
* A hot particle was discovered during a routine survey of the area adjacent to the 115 kV Switchyard in June 1977. The contaminant was removed and a resurvey of the entire area as well as equipment removed from the area indicated no remaining detectable activity.
The DWST and the CST was 'located to the southwest of the Containment Building in the northwest corner of the 115 kV Switchyard.
"  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.
Even though these tanks were designed to normally contain only non-radioactive water, there was a documented history of radiologically contaminated water occasionally being introduced into these systems.
"  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.

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.

The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9312-0003 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.

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.

SURVEY UNIT 9312-0003 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/a) 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 surface soil sample was taken at the east quadrant of the survey unit in the vicinity of former Excavation 3, one (1) judgmental sample was taken in the northwest comer 6f the survey unit in the vicinity of the PAB excavation and one (1) judgmental sample was taken in the vicinity of the former location of the DWST.

SURVEY UNIT 9312-0003 RELEASE RECORD 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.
SURVEY UNIT 9312-0003 RELEASE RECORD 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 4.07 mrem/yr TEDE. Therefore, Survey Unit 9312-0003 is acceptable for unrestricted release.

SOUTHWEST 115 KV SWITCHYARD (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0003 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9312-0003 (Southwest 115 kV Switchyard) is designated as Final Status Survey (FSS) Class 1 and consists of approximately one thousand four hundred eighty-six (1,486) square meters of open land and is located approximately one thousand four hundred seventy-seven feet (1,477 ft) to the southeast of the site benchmark.(Northing: 237370.20, Easting: 667394.57) associated with the site reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see ). The survey unit is bounded as follows: land Survey Unit 9312-0006 and land Survey Unit 9312-0001 to the north (called north as oriented with the north to south flow of the Connecticut River), land Survey Unit 9312-0001 and land Survey Unit 9312-0002 to the east, land Survey Unit 9312-0008 to the south, and land Survey Unit 9306-0000 to the west.

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 E008 through EO I1 by S068 through S070 (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 "Classification Basis Summary" conducted for Survey Unit 9312-0003 consisted of:

a) A review of the 10CFR50.75 (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.

Revision 0 3

SOUTHWEST 115 KV SWITCHYARD (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0003 RELEASE RECORD During plant operation, Survey Unit 9312-0003 was the location of significant reactor support structures and systems, including the southwestern corner of the Primary Auxiliary Building (PAB), the Feed Water/Steam Penetration Building (FW/STM),

the Shutdown Auxiliary Feed Pump House, the De-mineralized Water Storage Tank (DWST), the Condensate Storage Tank (CST) and the northwestern quadrant of the 115kV Switchyard.

The PAB was a concrete structure designed to house systems containing radioactive materials. The building was designed to contain and control leakage occurring during routine operations as well as unusual conditions.

With the exception of various service water, gas and air systems, the majority of the systems within the PAB were radiologically contaminated.

The PAB also contained highly contaminated pipe trenches and pump pit areas. The lower level of the PAB under the boron recovery equipment was contaminated due to past spills involving evaporator bottoms.

Contamination levels in several of these systems were high enough. to create high radiation areas in their vicinity.

Most of the cubicles that contained major systems were posted as "Contaminated Areas" identifying the presence of loose radioactive contamination in these areas.

Radiological surveys performed during facility operations indicated substantial levels of beta/gamma and alpha contamination.

Historically, leaks were found at the junction between the steam generator blow down line and the service water discharge line beneath the floor of the PAB drumming room. On at least one occasion, a leak resulted in contamination of the soil beneath the drumming room floor.

The FW/STM Penetration Building or "Terry Turbine Building" was located directly to the west of the Containment Building location. The building had three basic levels.

The lower level room contained auxiliary Feedwater pumps and piping, the middle level room contained the main steam dump valves and the upper level rooms housed the main steam stop valves. An outside catwalk that connected this building to the Service Building was located directly above Main Steam and Feedwater piping. The upper level also served as the alternate access HP control point to the Containment Building during decommissioning.

The FW/STM Penetration Building was maintained free of loose radioactive contamination during facility opera tion. Periodic radiological surveys were routinely performed to substantiate this radiological condition.

The Electric Shutdown Auxiliary Feed Pump House contained the Electric Shutdown Auxiliary Feed Pump and all above grade DWST piping.

The building was an independent structure with outer aluminum siding, inner sheetrock walls, slightly tapered sheet metal roof, asphalt floor, a building exhaust ventilation and a concrete support base beneath the pump. No significant radiological events were identified regarding this building.

SOUTHWEST 115 KV SWITCHYARD (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0003 RELEASE RECORD The 115 kV Switchyard (#111) was situated outside the RCA just south of the Containment building. This area included two Station Service Transformers (# 204 &

  1. 205) and the 115 kV Tie Breaker (#218). Also, Bus 12 (#120) was located at the SW corner of the yard.

In addition, there were several other transformers with associated power lines that extended beyond the switchyard area.

The DWST and CST were also designated as Tank "TK-25-lA" and Tank "TK IB" respectively.

The DWST and the CST was 'located to the southwest of the Containment Building in the northwest corner of the 115 kV Switchyard.

Even though these tanks were designed to normally contain only non-radioactive water, there was a documented history of radiologically contaminated water occasionally being introduced into these systems.

Events that may have contributed to the introduction of contaminated water into these tanks were steam generator tube failures and misalignment of valves. Historical surveys performed in the vicinity of these tanks did not indicate any significant levels of radioactive contamination.

During April 1999, a shallow monitoring well and a deep monitoring well on the west side of the DWST produced samples that showed positive results for tritium.

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 9312-0003. 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; A hot particle was discovered during a routine survey of the area adjacent to the 115 kV Switchyard in June 1977. The contaminant was removed and a resurvey of the entire area as well as equipment removed from the area indicated no remaining detectable activity.

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.

SURVEY UNIT 9312-0003 RELEASE RECORD Major demolition and remediation activities began in 2002. All radioactive systems and components located inside the PAB 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 structural concrete of the PAB and FW/STM Penetration Building was then demolished to grade. The Electric Shutdown Auxiliary Feed Pump House, the DWST, the CST and the concrete base pads for all three (3) structures were completely demolished and removed.

No above grade structures currently reside within Survey Unit 9312-0003.

Outside of the structures, remediation was performed on the soils surrounding the PAB. The excavation around the PAB footing was designated as Excavation #2; the excavation around the FW/STM Penetration Building was designated as Excavation

  1. 6 and the excavation adjacent to the Containment Building in the east section of the survey unit was designated as Excavation #3.

Remediation was successfully performed in these areas by the excavation of all affected soils to the beginning of the saturated zone or to 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.

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.

SURVEY UNIT 9312-0003 RELEASE RECORD 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.

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 I (refer to Section 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 9312-0003 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 I shows the mathematical relationship between the three (3) components and the total dose.

Equation 1 HTotaI =H Soil + HExistingGW + HFutureGW Revision 0 8

SOUTHWEST 115 KV SWITCHYARD (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0003 RELEASE RECORD 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/yrFutureGW 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.

SOUTHWEST 115 KV SWITCHYARD (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0003 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 9312-0003 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 9312-0003 (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.

SOUTHWEST 115 KV SWITCHYARD (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0003 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/a) 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 surface soil sample was taken at the east quadrant of the survey unit in the vicinity of former Excavation 3, one (1) judgmental sample was taken in the northwest comer 6f the survey unit in the vicinity of the PAB excavation and one (1) judgmental sample was taken in the vicinity of the former location of the DWST.

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.

Each sample was sent off-site for a full suite analysis of the HTD radionuclides specified in the LTP, Table 2-12, "Radionuclides Potentially 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" 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. Table 5 provides a synopsis of the survey design.

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 9312-0003. 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 7,770 counts per minute (cpm) up to 12,500 cpm.

SOUTHWEST 115 KV SWITCHYARD (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0003 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 (9312-0003-002F, 9312-0003-012F and 9312-0003-015F) were randomly selected for HTD radionuclide analysis.

Subsequently, all samples were subjected to analysis by gas proportional counting for Sr-90. All analyses met the required minimum MDC.

Sr-90 was positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in only one (1) of the fifteen (15) samples collected for non-parametric statistical testing. Sr-90 was observed in sample 9312-0003-007F at a concentration of 3.65E-02 pCi/g or 4.1% of the Operational DCGL for Sr-90 of 9.30E-0 1 pCi/g.

In addition to Sr-90, the off-site laboratory also processed, as required by the sample plan, three (3) 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 detected.

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.

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 Final Status Survey ".

SURVEY UNIT 9312-0003 RELEASE RECORD Cs-137 was not detected in sufficient quantity in the field split results at location 9312-0003-009FS 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. Refer to Attachments 3 and 4 for data and data quality analysis results

8.

INVESTIGATIONS AND RESULTS There were no investigations performed for this survey

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 Cs-137 and Co-60 were not positively detected in any of the samples collected for non-parametric statistical testing. Subsequently, a statistical analysis of the data sets for any of these radionuclides would provide no useful information.

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.

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.

Sr-90 was positively identified in only one (1) of the samples collected for non-parametric statistical testing. Subsequently, a statistical analysis of the data sets for any of these radionuclides would provide no useful information.

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

12.

ANOMALIES No anomalies were noted.

13.

CONCLUSION Survey Unit 9312-0003 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 0.07 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.

Revision 0 20

SOUTHWEST 115 KV SWITCHYARD (FORMER RADIOLOGICALLY CONTROLLED AREA)

SURVEY UNIT 9312-0003 RELEASE RECORD 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 4.07 mrem/yr TEDE. Therefore, Survey Unit 9312-0003 is acceptable for unrestricted release.

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 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.

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

Preparation or preservation holding time was exceeded

[VA 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.

The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the imple is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is

ss than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.

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

Vhere the analytical method has been performed under NELAP certification, the analysis has met all of the

-quirements of the NELAC standard unless qualified on the QC Summary.
