NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9506-0000, North Site Grounds (Non-Protected Area)/

Emergency Operations Facility (EOF), is designated as Final Status Survey (FSS) Class 3 and consists of approximately eleven thousand two hundred forty four square meters 11,244 m2 (2.77 acres) of open land area located approximately 0.08 miles from the reference coordinate system benchmark used at the Haddam Neck Plant (HNP) (see Attachment 1, Figure 1). The North Site Grounds survey unit is bounded as follows: on the west by the Survey Unit 9512-0000; Survey Unit 9504-0000 is to the east; Survey Unit 9514-0000 is to the south and the property boundary bounds this unit to the north (called north as oriented with the north to south flow of the Connecticut River). The Storm Water Retention Pond, Survey Unit 9508-0000, is located in the interior of the survey area.

The survey unit is comprised of predominately flat open land area.

The survey unit slopes from north to south, in the direction of the pond.

The area around the pond is densely populated with trees and small brush.

The EOF building is located within the survey unit. Several sea land storage containers are located in the northern portion of the survey unit. These sea land storage containers are used for storage and preparation of FSS samples and miscellaneous materials.

The EOF structure will remain on-site and several underground structures will be abandoned in place (i.e. a septic system; two (2) electric/telephone duct banks; a well water storage tank; and several storm water culverts associated with the bypass road). Radiological surveys will be performed to confirm that the components or structures will meet all applicable unrestricted release criteria (reference CY memo CY 093 and License Termination Plan (LTP) Section 2.3.3.1.2.7).

The reference coordinates associated with this survey area are E005 through E011 by S039 through S052 (refer to LTP Section 5.4.4, Figure 5-2). 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 historical information, scoping analyses and characterization results provided sufficient data to designate Survey Unit 9506-0000 as Class 3 in May 2006.

Revision 0 3

Revision 0 3

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD The "Classification Basis Summary" conducted for this survey unit consisted of:

a) A review of the 10CFR50.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historical Site Assessment (HSA) Supplement,"

c) Historic and current survey records review, d) Visual inspections and a "walk-down."

A review of the 10CFR50.75 (g) (1) database report identified one (1) significant radiological event that may have impacted this survey area.

In March 1980, Plant Incident Report (PIR) 80-37 reported the discovery of several areas of elevated activity throughout the site. The investigation into the incident concluded that the elevated activity was most likely ejected from the Primary Vent Stack as a result of operational events in 1979. In all cases, the areas of elevated activity were removed upon discovery.

A review of the historical documents included the "Results of Scoping Survey", (performed during late 1997) and the "Historical Site Assessment" which provided no additional information.

A review of the "Initial and Supplemental Characterization Reports" as well as the previous "Classification Basis Summaries " provided no additional information pertinent to the classification.

Characterization was performed in June 2006 to obtain data of sufficient quality for Final Status Survey (FSS) planning purposes. This sampling was performed under Survey Sampling Work Plan (SSWP) 06-06-006. Nine (9) soil samples were evaluated overall. All of the samples were analyzed on-site using gamma spectroscopy. A Hard-to-Detect (HTD) analysis was conducted on one (1) of the nine (9) samples. Statistical quantities (mean, median and standard deviation) from the 2006 characterization survey are provided in Table 1).

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD 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.

The final designation was Class 3 based on historical information and the characterization survey data which provided sufficient data to conclude that FSS sample results will be a fraction of the Operational DCGL of nineteen (19) mrem/yr.

DATA QUALITY OBJECTIVES (DQO)

FSS design and planning is based on 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 is provided herein.

The DQO process incorporates 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 defined 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 satisfy the release criteria objective of the FSS. Probabilistic sampling is a preferred method to select a sample so that each item in the population being studied has a known likelihood of being included in the sample.

Probabilistic sampling may include simple random sampling where every sample has the same chance of being included, or systematic random sampling where samples are arranged in some order and a random starting point is selected.

The primary objective of the Final Status Survey Plan (FSSP) was to demonstrate that the level of residual radioactivity in Survey Unit 9506-0000 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 Derived Concentration Guideline Levels (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 for future groundwater radioactivity that will be contributed by building foundations and footings.

Revision 0 5

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD 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 (sediment) + HExisting GW + HFuture GW 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 Connecticut Yankee (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 (reference CY memo ISC 06-024).

This survey unit is not affected by existing groundwater radioactive contamination (reference CY memo ISC 06-024).

Therefore the dose contribution from existing groundwater is zero (0) mrem/yr TEDE.

This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no contaminated concrete foundations or footings remaining 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.

Equation 2.

19 mrem/yrTotal= 19 mrem/yrsoj1+0 mrem/yrExisting GW+O mrern/yrFuture GW The allowable dose for soil in this survey unit is nineteen (19) mrem/yr TEDE as shown by Equation 2 above.

The concentration of residual radioactivity resulting in nineteen (19) mrem/yr TEDE is designated as the Operational DCGL(s), and has been established for the radionuclides of concern as provided in Table 2.

The Base Case Soil DCGLs for soil are specified by the LTP in Chapter 6 and are equivalent to twenty-five (25) mrem/yr TEDE The Operational DCGL is equivalent to nineteen (19) mrem/yr TEDE The required MDC is equivalent to one (1) mrem/yr TEDE Americium-241 can be analyzed by gamma and alpha spectroscopy and is considered to be Easy to Detect (ETD). The preferred result is the alpha spectroscopy's when both analyses are performed.

Revision 0 7

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD Another important facet of the DQO process is to identify the radionuclides of concern and determine the concentration variability. Characterization was performed in June of 2006 as discussed in Section 2. Cs-137 was found to be the only radionuclide of concern. The basic statistical quantities (i.e., mean, standard deviation, median) for Cs-137 are provided in Table 1.

Laboratory DQOs and analysis results were to be reported as actual calculated results. Results reported as less than Minimum Detectable Concentration

(<MDC) would not be accepted for FSS. Sample report summaries were to include unique sample identification, analytical method, radionuclide, result, and uncertainty of 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 FSSP uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.

The dose for soil, used in this survey area to demonstrate compliance with the LTP criteria, is nineteen (19) mrem/yr TEDE, as discussed in Section 3 of this Release Record.

The DQO process determined that Cs-137 was the radionuclide of concern in Survey Unit 9506-0000 (refer to Section 3). 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 Elevated Measurement Comparison (EMC) did not apply to this survey unit since the survey unit is a Class 3 and discrete, elevated areas of contamination were not expected.

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

The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Samples for Final Status Survey. " The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11, "Preparation of Final Status Survey Plans" to 5.93 pCi/g Cs-137 to maintain the relative shift (A/a) in the range of 1 and 3. The resulting relative shift was 2. A Prospective Power Curve was generated using COMPASS, a software package developed under the Revision 0 8

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD sponsorship of the United States Nuclear Regulatory Commission (USNRC) for implementation of 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. This indicates that the survey area has a high probability of rejecting the null hypothesis, assuming that the characterization data are representative of the FSS results.

Survey design specified fifteen (15) soil samples for non-parametric statistical testing.

The 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 random location was selected for sample design, which is appropriate for a Class 3 area.

Sample locations were identified using AutoCAD-LT, 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.

The sample location designations of Table 3 are not sequential due to changes made at the south boundary of Survey Unit 9506-0000.

The locations of three (3) of the fifteen (15) samples to be used for non-parametric-statistical testing were absorbed into Survey Unit 9514-0000.

Three (3) new sample locations, 9506-0000-018F, 9506-0000-019F and 9506-0000-020F were determined using VSP in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locations for Final Status Survey. "

Judgmental or biased sampling was included as a feature of this survey design to account for any anomalies potentially identified in the field.

Sample numbers 9506-0000-016F and 9506-0000-017F identify the biased sample locations that were selected for this survey unit.

Although Procedure RPM 5.1-11, "Preparation of Final Status Survey Plans " only specified that 5% of the samples be selected for HTD analysis, two (2) soil samples or 13% of the samples collected for non-parametric testing were analyzed for HTDs, exceeding the required percentage. The two (2) samples that were tested, were randomly selected for HTD radionuclide analyses using the Microsoft Excel "RANDBETWEEN" function.

Each sample was sent off-site for a full suite analysis of the HTD radionuclides specified in Table 2.

The implementation of survey specific quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey, " included the collection of two (2) soil samples for "split sample" analysis by the off-site laboratory. These locations were selected randomly using the Microsoft Excel "RAND" function. The number of quality control samples exceeded the 5% requirement.

The LTP specifies that scanning will be performed along with random and judgmental measurements (samples) for a

Class 3

survey unit.

Approximately 10% of this survey unit was scanned. Scanning was biased to areas where contamination was previously located and remediated in 1980 (PIR 80-37). Table 4 provides a synopsis of the survey design.

SURVEY IMPLEMENTATION Final Status Survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 2006-0038.

The WP&IR package included a detailed FSSP, 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.

Initially six (6) scan areas were established that constituted approximately 10% of the surface area of the Survey Unit 9506-0000. In January 2007, two (2) scan areas were absorbed into Survey Unit 9514-0000.

One (1) additional scan area was established in the redrawn survey unit. The total number of scan areas was five (5) and the total area scanned remained approximately 10% of the surface area. Grid lines, one (1) meter wide, were established in each of the five (5) scan areas. Background was established at Revision 0 I1I Revision 0 11

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD the beginning of each grid line, prior to scanning, using an Eberline E-600 with a SPA-3 sodium iodide detector. The E-600 was operated in the rate-meter mode and used with the audio response.

Fifteen (15) 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."

Initially two (2) samples, 9506-0000-004F and 9506-0000-013F, were selected, at random for HTD radionuclide analysis by the off-site laboratory.

Sample 9506-0000-004F was absorbed into Survey Unit 9514-0000. Sample 9506-0000-019F was randomly selected to replace sample 9506-0000-004F.

Two (2) biased soil samples 9506-0000-016F and 9506-0000-017F were collected to be analyzed by the offsite laboratory for gamma spectroscopy.

The implementation of survey specific quality control measures included the collection of two (2) split samples at locations 9506-0000-002F and 9506-0000-008F for "split sample" analysis by the off-site laboratory.

The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories (GEL) - Charleston, South Carolina. The laboratory analyzed the fifteen (15) samples taken for non-parametric statistical testing and the associated duplicates using gamma spectroscopy.

Gamma spectroscopy analysis was performed to the required MDC. Gamma spectroscopy results identified some radionuclides meeting the acceptance criteria for detection (i.e., a result greater than two (2) standard deviations Revision 0 13

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD uncertainty). All could be de-selected or excluded using the 5% and 10% rule described in Section 4.

Cesium-137 was identified in twelve (12) of the fifteen (15) samples. None of the samples exceeded the Operational DCGL.

Gamma spectroscopy sample analysis did not require further investigation.

The Operational DCGLs from Table 2 is 6.01 pCi/g for Cs-137 to achieve nineteen (19) mrem/yr TEDE.

The off-site laboratory also processed two (2) samples for HTD analyses as required by the sample plan.

The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method. Gamma spectroscopy results identified some radionuclides meeting the acceptance criteria for detection (i.e., a result greater than two (2) standard deviations uncertainty). All could be de-selected or excluded using the 5% and 10% rule described in Section 4.

All analyses met the required MDC.

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

The data was evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for Final Status Survey. " There was acceptable agreement between the field split results for both of the "split sample" pairs tested.

The sample analysis vendor, General Engineering Laboratories (GEL) -

Charleston, South Carolina, maintains quality control and quality assurance plans as part of normal operation. Refer to Attachment 2 for data and data quality analysis results.

8.

INVESTIGATIONS AND RESULTS Sample investigation levels were not exceeded for this unit. Consequently, no investigations were performed.

9.

REMEDIATION AND RESULTS Historically, no radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS.

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 to be unnecessary and that the remaining residual radioactivity in soil was ALARA.

CHANGES FROM THE FINAL STATUS SURVEY PLAN Addendum #1 was drafted to address sample location, 9506-0000-013F that was underwater at the time the FSSP was initiated. The addendum was not used due to receding water. Sample location 9506-0000-013F was taken at its original randomly selected location.

Addendum #2 was drafted to address the change in the south boundary of Survey Unit 9506-0000, the locations of three (3) of the fifteen (15) samples that were used for non-parametric statistical testing and two (2) scan areas were absorbed into Survey Unit 9514-0000 and a new scan area was established. Approximately eight hundred seventy six square meters (876 M 2) of the survey unit were absorbed by Survey Unit 9514-0000

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 Sign Test shows that the survey unit passes FSS.

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 3.

The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). See Table 9.

Table 9 -

Basic Statistical Quantities for Cs-137 from the Final Status Survey Cs-137 pCi/g DCGLop:

6.01E+00 Minimum Value:

7.99E-02 Median:

5.52E-02 Standard Deviation:

7.11 E-02 Revision 0 16

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD The sample standard deviation was slightly more than the value used for the survey design. This is represented by the shift in the retrospective power curve as shown in Attachment 2f. This would indicate a change to the original LBGR to maintain the number of samples at fifteen (15) to meet the Operational DCGL. However, the value of LBGR is less of a critical issue as the survey unit has passed the statistical test, and 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 release criteria with adequate power as required by the DQOs.

The range of the data was about 2.81 standard deviations. The difference between the mean and median was 38.6% 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 shows some positive skewness as confirmed by the calculated skew of 1.21.

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

12.

ANOMALIES No anomalies were noted in the performance of this FSS.

13.

CONCLUSION Survey Unit 9506-0000 has met the final DQOs of the FSS. The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved. Elevated Measurement Comparison and remediation were not required.

The sample data passed the Sign Test. The null hypothesis was rejected.

Graphical representation of data indicates some positive skewness that is probably due to the differences in terrain and the collection of runoff. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. The survey unit was properly designated as Class 3.

The dose contribution from soil is 0.253 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.

This survey unit is not affected by existing groundwater (reference CY memo ISC 06-024). The dose contribution from existing groundwater is zero (0) mrem/yr TEDE.

This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no radioactive 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.

Revision 0 17

NORTH SITE GROUNDS (NON-PROTECTED AREA)/EOF SURVEY UNIT 9506-0000 RELEASE RECORD The average total dose from residual radioactivity in this survey unit is 0.253 mrem/yr TEDE.

Concentrations are <5X the RL A

The TIC is a suspected aldol-condensation product B

Target analyte was detected in the associated blank B

Metals-Either presence of analyte detected in the associated blank, or MDL/IDL < sample value < PQL BD Results are either below the MDC or tracer recovery is low C

Analyte has been confirmed by GC/MS analysis D

Results are reported from a diluted aliquot of the sample d

5-day BOD-The 2:1 depletion requirement was not met for this sample E

Organics-Concentration of the target analyte exceeds the instrument calibration range E

Metals-%difference of sample and SD is

.10%.

Sample concentration must meet flagging criteria H

Analytical holding time was exceeded h

Preparation or preservation holding time was exceeded J

Value is estimated N

Metals-The Matrix spike sample recovery is not within specified control limits N

Organics-Presumptive evidence based on mass spectral library search to make a tentative identification of the analyte (TIC).

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.
