SUBSURFACE AREA ASSOCIATED WITH THE SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9807-0000 RELEASE RECORD

1.

SURVEY UNIT DESCRIPTION Survey Unit 9807-0000 (Subsurface Area associated with the Southwest Site Storage Area) is designated as Final Status Survey (FSS) Class B and consists of 1,983 m2 (0.5 acres) of uninhabited open land located approximately 1,860 feet from the reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see Attachment 1). The surface area is bounded by Survey Unit 9520-0004. The surface land unit that resides above this subsurface survey unit is relatively level open space of the peninsula. The restoration of the peninsula for FSS has removed most of the surface interference in the survey unit.

The reference coordinates associated with this survey unit are E007 through E0I10 by S089 through S093 (refer to 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 9807-0000 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 10CFR50.75(g)(1) database report and historical files shows a documented history of the Southwest Site Storage Area as a radioactive materials storage area. Examples of some of the major events are provided below.

a) Plant Incident Report (PIR) 80-37 reported the discovery of three (3) discrete sources of elevated activity on the Southeast Site Storage area in March 1980, along with other areas around the site.

The three (3) discrete sources were identified within adjacent Survey Units 9520-0001 and 9520-0002.

The elevated areas were removed upon detection according to the.report.

.RELEASE RECORD b) Health Physics surveys performed in 1983 and 1985 document the discovery of radioactive material (strainers, bolts, wood pallets, sections of pipe, etc.) on the peninsula.

The 1985 survey documents the discovery of contaminated dirt under a pallet.

c) Condition Report (CR) 05-0314: Documents the discovery of excavation spoils, intended for backfill, above the radiological criteria for use as backfill. These spoils were likely located in Survey Units 9520-0003 and 9520-0004, based on a review of the documentation. According to the CR closure documentation, the affected spoils were removed and packaged for disposal. Follow-up survey and sampling was performed and the results were below established action levels.

A review of the "Initial and Supplemental Characterization Reports" as well as the previous "Classification Basis Summaries" was performed.

Survey Unit 9807-0000 was originally part of subsurface Survey Unit 9805-0000, which was initially designated as Class C during the development of the LTP.

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 (references 2-2 and 277 respectively). The second source document justified a Class C designation for those areas for which there was historical evidence of contamination above the Derived Concentration Guideline Levels (DCGLs -

refer to Section 2 for definition and description of DCGL), but for which recent surveys had shown that decontamination efforts had occurred and that the radiological conditions were expected to be below the DCGLs. Additional justification for a Class C designation based on survey and sampling data was provided as another reference to the LTP by the "Haddam Neck Plant Historical Site Assessment Supplement".

However, in March of 2006, Co-60 and Cs-137 were identified in subsurface soils in sufficient quantities to warrant radiological remediation. Radiological remediation was performed in July 2006. A new Class 1 survey unit, Survey Unit 9520-0004, and a new subsurface unit, Survey Unit 9807-0000, were established to bound the area of remediation.

Remedial action was performed in July 2006.

Although Co-60 has been identified in the past, Cs-137 was the only radionuclide with the potential to exceed the screening criteria following the remedial action.

Statistical quantities (mean, median and standard deviation) from the 2006 remedial action survey are provided in Table 1.

8.39E-03 The FSS Engineer performed a visual inspection and walk-down during September 2006 to assess the physical condition of the survey unit, evaluate access points, and travel paths and identify potentially hazardous conditions.

This survey area is affected by existing 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 results of radiological surveys performed over six years of restoration and the 2006 remedial action survey, it was concluded that there was a probability for residual radioactivity in concentrations less than the DCGLs, justifying a final survey unit classification of Class B (refer to Section 3). Note, due to the size of the survey unit, the sample to area frequency far exceeds the frequency requirement for Class A survey units of one sample every 500 m2 as specified by LTP Section 5.7.3.2.2.

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. Therefore, the survey unit does satisfy the primary objective of the FSS plan.

The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 9807-0000 did not exceed the release Revision 0 5

Revision 0 5

SUBSURFACE AREA ASSOCIATED WITH THE SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9807-0000 RELEASE RECORD 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 I HTotal =Hsoil + HExistingGW + HFutureGW The total dose under the LTP criteria is twenty-five (25) mrem/yr 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) mremryr 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 not considered impacted by future groundwater radioactive contamination, as there are no buried concrete foundations or footings 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, therefore, zero (0) mrem/yr TEDE.

Equation 2 19 mrem/yrTotal = 17 mrem/yrsoil + 2 mrem/yrExisting GW+ 0 mrem/yrFutureGw Revision 0 6

SUBSURFACE AREA ASSOCIATED WITH THE SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9807-0000 RELEASE RECORD The allowable dose for soil in this survey unit is seventeen (17) mrem/yr TEDE as shown by Equation 2 above.

The concentration of residual radioactivity resulting in seventeen (17) mrem/yr TEDE is designated as the Operational DCGL, and has been established for the radionuclides of concern as provided in Table 2.

SUBSURFACE AREA ASSOCIATED WITH THE SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9807-0000 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 during the remedial action survey.

Cs-137 was the only gamma emitting radionuclide reported in concentrations with the potential for exceeding the screening criteria. The remedial action survey 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 would be the radionuclide of concern in Survey Unit 9807-0000 (refer to Section 3). Other radionuclides identified during this FSS would be evaluated to ensure adequate survey design.

Surrogate DCGLs were not required for this survey unit via screening under LTP Section 5.4.7.2, "Gross Activity DCGLs". 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 Elevated Measurement Comparison (EMC) did not apply to this survey unit since it is a Class B area and discrete, elevated areas of contamnination were not expected.

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.

Revision 0 8

SUBSURFACE AREA ASSOCIATED WITH THE SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9807-0000 RELEASE RECORD The number of soil samples for FSS was determined in accordance with the LTP. The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 5.36 to maintain the relative shift (A/o) 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 (10 CFR 20, Subpart E). The result of the COMPASS computer run showed adequate power for the survey design.

The survey design specified twenty-five (25) core soil samples for non-parametric statistical testing.

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 f.or 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 B area.

Judgmental sampling was not detennined to be necessary by the DQOs, based on the short distance between the area that was subjected to remedial action and FSS sample location 9807-0000-012F.

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 3.

Three (3) 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 "RANDBETWEEN" function. 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 2.

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 three (3) soil samples for "split sample" analysis by the off-site laboratory. These locations were selected randomly using the Microsoft Excel "RANDBETWEEN" function. The number of quality control soil samples was about 10% of twenty-five (25) samples.

The LTP does not require scanning for elevated areas of radioactivity in subsurface survey units.

For this Class B survey unit, the "Investigation Level" for soil sample measurement results are those levels specified in LTP, Table 5-8.

Table 4 provides a synopsis of the survey design.

SURVEY IMPLEMENTATION FSS field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0038. The WP&IR package included a detailed FSS 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.

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.

Twenty-five (25) subsurface 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 (9807-0000-003F, 9807-0000-008F and 9807-0000-013F) were randomly selected for HTD radionuclide analysis.

The implementation of survey specific quality control measures included the collection of three (3) samples (9807-0000-012F, 9807-0000-018F and 9807-0000-024F) for "split sample" analysis.

SURVEY RESULTS All field survey activities were conducted between September 13, 2006 and September 21, 2006.

The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC. The laboratory analyzed the twenty-five (25) samples collected for non-parametric statistical testing, and 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 standard deviations uncertainty). However, Cs-137 was the only radionuclide reported in concentrations exceeding the de-selection criteria.

Cs-137 was identified in eight (8) of the twenty-five (25) samples collected for non-parametric statistical testing.

Cs-137 was the primary radionuclide confirming the DQOs. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels lower than the concentrations of Cs-137 found in soil at off-site locations within the vicinity of the HNP as presented in the Health Physics TSD BCY-HP-0063.

A summary of the twenty-five (25) samples collected for non-parametric statistical testing results is provided in Table 5.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. All analyses met the required MDC.

As previously stated in Section 4 of this report, the criteria for de-selection of a radionuclide is a concentration that is less than 5% of the Operational DCGL for individual radionuclides and less than 10% of the Operational DCGLs for aggregates. H-3 and Am-241 were the only HTDs identified above the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty). The off-site laboratory prepared and reanalyzed two (2) of the three (3) original samples for H-3 at HNP's request; and performed H-3 analysis on five (5) other samples bordering the two (2) sample locations. The results of all seven (7) samples were all less than the accepted criteria for detection. The highest result for Am-241 was about 4% of the Operational DCGL.

QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis.

Ten percent (10%) of the samples were 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 quantities in the field split results at the three (3) locations 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.

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

8.

INVESTIGATIONS AND RESULTS No investigations were performed.

9.

REMEDIATION AND RESULTS Remedial action was performed in July 2006.

Although Co-60 has been identified in the past, Cs-137 was the only radionuclide with the potential to exceed the screening criteria following the remedial action. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " has determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in soil was ALARA.

10.

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

11.

DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessment, " for completeness and consistency.

The sampling design had adequate power as indicated by the Retrospective Power Curve. The Sign Test was performed on the data and compared to the original assumptions of the DQOs. The evaluation of the Sign Test results demonstrates that the survey unit passes the unrestricted release criteria, thus, the null hypothesis is rejected.

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 B.

Revision 0 14 Revision 0 14

SUBSURFACE AREA ASSOCIATED WITH THE SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9807-0000 RELEASE RECORD 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.

For Cs-137, the range of the data, about five (5) standard deviations, indicated some variation, mainly as a result of one (1) sample that is higher in concentration than the rest of the data set. The difference between the mean and median was about 20% 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 significant positive skewness due to one (1) sample as confirmed by the calculated skew of 4.99.

All data, assessments, and graphical representations are provided in Attachment 3.

12.

ANOMALIES No anomalies were noted.

13.

CONCLUSION Survey Unit 9807-0000 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.

Cs-137 was 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 B.

The dose contribution from soil is less than 1 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 not considered impacted by future groundwater radioactive contamination, as there are no underground structures, systems or components containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024); therefore, the dose contribution from future groundwater is zero (0) mrem/yr TEDE.

Revision 0 15 Revision 0 15

SUBSURFACE AREA ASSOCIATED WITH THE SOUTHWEST SITE STORAGE AREA SURVEY UNIT 9807-0000 RELEASE RECORD 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

.3 mrem/yr TEDE.

Therefore, Survey Unit 9807-0000 is acceptable for unrestricted release.

The Qualifiers in this report are defined as follows:

A quality control analyte recovery is outside of specified acceptance criteria Result is less than value reported Result is greater than value reported A

The TIC is a suspected aldol-condensation product B

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 R

Sample results are rejected U

Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.

UI Gamma Spectroscopy--Uncertain identification X

Consult Case Narrative, Data Summary package, or Project Manager concerning this qualifier Y

QC Samples were not spiked with this compound A

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

Preparation or preservation holding time was exceeded 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.

^ 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.

'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.

^ 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.

Wheore 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.
