NORTHWEST SITE GROUNDS (NON-PROTECTED AREA)
SURVEY UNIT 9512-0000 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9512-0000, Northwest Site Grounds, is designated as Final Status Survey (FSS) Class 3 and consists of approximately 30,701 m2 (7.58 acres) of open land area located approximately 0.007 miles from the reference coordinate system benchmark used at the Haddam Neck Plant (HNP) (see Attachment 1, Figure 1).
The Northwest Site Grounds survey unit is bounded as follows: on the west by the Connecticut River; Survey Area 9506-0000, 9514-0000, 9302-0000 and 9304-0001 are to the east; Survey Area 9304-0001 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 survey unit is comprised of predominately flat open land that slopes, slightly, from east to west toward the Connecticut River. At the far northeastern end of the survey unit, the topography changes from flat to steep hillside. The hillside is covered with large trees and thick brush. At the southern most section of the survey unit, the area is a steep hillside that falls off to the Connecticut River.
Connecticut Yankee (CY) memorandum, CY-06-093, addresses the abandonment of buried pipes, concrete, and drains onsite that will remain in place at the completion of the decommissioning. The sidewalk and two (2) electric/telephone duct banks that traverse the site adjacent to the access road will be abandoned in place.
Sufficient radiological assessment has been performed to confirm that the components or structures will meet all applicable unrestricted release criteria.
The reference coordinates associated with this survey area are E002 through E008 by S039 through S064 (refer to License Termination Plan 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 area. The boundary of the survey area was defined using a Global Positioning System (GPS) based on the Connecticut State Plane System North American Datum (NAD) 1927.

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 9512-0000 as Class 3 in May 2006.
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 "Historic Site Assessment (HSA) Supplement, "
Revision 0 3
NORTHWEST SITE GROUNDS (NON-PROTECTED AREA)
SURVEY UNIT 9512-0000 RELEASE RECORD c) Historic and current survey records review, d) Visual inspections and a "walk-down."
A review of the IOCFR50.75(g)(1) database report identified one (1) significant radiological event that may have impacted this survey area.
Several small areas of low-level radioactive contaminated material were found on facility grounds through routine testing. (PIR 80-37)
The radioactive material was removed and no further radioactive material was located.
The historical documents reviewed included the "'Results of Scoping Survey",
(performed during late 1997) and the "Historical Site Assessment". No additional information was provided that was pertinent to this survey unit.
A review of the "Initial and Supplemental Characterization Reports " as well as the previous "Classification Basis Summaries " also provided no additional pertinent information.
Final characterization was performed by Site Closure personnel in May of 2005 to obtain data of sufficient quality for Final Status Survey (FSS) planning purposes.
This sampling was performed under Survey Sampling Work Plan (SSWP) 05-05-014. Ten (10) soil samples were taken from ten (10) biased locations. All of the samples were analyzed on-site using gamma spectroscopy. Hard-to-Detect (HTD) analyses were conducted on one (1) of the ten (10) samples. The only plant-related radionuclide identified in the samples was Cs-137 (refer to Table 1).

SURVEY UNIT 9512-0000 RELEASE RECORD Based upon a review of the historical information and the results of the characterization survey data, it was concluded that there was a low probability for residual radioactivity in concentrations greater than the Derived Concentration Guideline Levels (DCGLs), justifying a final survey unit classification of Class 3.
- 3.
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 the level of residual activity in the survey unit exceeded the release criteria. Therefore, the survey unit would satisfy the primary objective of the Final Status Survey Plan (FSSP).
The primary objective of the FSSP was to demonstrate that the level of residual radioactivity in Survey Unit 9512-0000 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 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.
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.

NORTHWEST SITE GROUNDS (NON-PROTECTED AREA)
SURVEY UNIT 9512-0000 RELEASE RECORD 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 considered affected by existing groundwater radioactive contamination (reference CY memo ISC 06-024). Therefore, the dose contribution from existing groundwater is two (2) mrem/yr TEDE.
This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no radioactive concrete foundations or footings remaining within the groundwater saturated zone in the area.
Therefore, the dose contribution from future groundwater is zero (0) mrem/yr TEDE.
Equation 2:
19 mrem/yrTotal= 17 mrem/yrsoil+2 mrem/yrExisting GW+O mrem/yrFuture GW 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(s), and has been established for the radionuclides of concern as provided in Table 2.

NORTHWEST SITE GROUNDS (NON-PROTECTED AREA)
SURVEY UNIT 9512-0000 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 May of 2005 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 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 DQO process determined that Cs-137 would be the radionuclide of concern in survey unit 9512-0000 (refer to Section 3). The characterization survey did not identify any HTD radionuclides of concern for this survey unit.
Other radionuclides identified during FSS would be evaluated to ensure adequate survey design and compliance with the unity rule.
Surrogate DCGLs were not required for this survey unit based on process knowledge from FSS of nearby adjacent areas and 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 aggregate 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 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.

SURVEY UNIT 9512-0000 RELEASE RECORD 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 2.69 pCi/g Cs-137 to maintain the relative shift (A/CT) 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 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. Survey design specified fifteen (15) 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 for Final Status Survey."
Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. A random grid pattern with a random starting point was selected for sample design, which is appropriate for a Class 3 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 3.

The initial design of the survey unit included area that was not within the property boundary. This was discovered during implementation of FSS. Addendum 1 to FSSP 9512-0000 was written to address the collection of three (3) additional samples.
Sample locations 9512-0000-017F/FS, 9512-0000-018F and 9512-0000-019F were selected randomly, in accordance with the FSSP 9512-0000 Addendum 1, as determined by using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying and Marking Surface Sample Locations for Final Status Survey".
Judgmental sampling was included as a feature of this survey design to account for any anomalies identified in the field.
Sample location 9512-0000-016F was selected as a judgmental location.
The judgmental sample location was selected based on its proximity to an area where radioactive material previously located and removed in 1980 (PIR 80-37).
Procedure RPM 5.1-11, "Preparation of Final Status Survey Plans " specifies that 5% of the samples are required to be selected for HTD analysis. Two (2) soil samples or 13% 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 "RAND" 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.

NORTHWEST SITE GROUNDS (NON-PROTECTED AREA)
SURVEY UNIT 9512-0000 RELEASE RECORD 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.
Three (3) scan areas were established that constituted approximately 10% of the surface area of the Survey Unit 9512-0000. Grid lines, one meter wide, were established in each of the three (3) scan areas.
Background was established at the beginning of each grid line, prior to scanning, using an Eberline E-600 with a SPA-3 sodium iodide detector, background ranged from 5,200 counts per minute (cpm) up to 8,700 cpm.
The E-600 was operated in the rate-meter mode and used with the 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 in a serpentine pattern.
Fifteen (15) soil samples were collected for non-parametric statistical testing and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Media for Final Status Survey" and FSS design.
Samples were controlled, transported, stored, and transferred to the off-site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples. "
Two (2) samples (9512-0000-003F and 9512-0000-007F) were randomly selected for HTD radionuclide analysis by the off-site laboratory.
One (1) biased soil sample, 9512-0000-016F, was collected and 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 9512-0000-014F and 9512-0000-017F 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 standard deviations uncertainty). All could be de-selected or excluded using the 5% and 10% rule described in Section 4.
Cs-137 was identified in eleven (11) of the fifteen (15) samples. None of the samples exceeded the Operational DCGL.
Gamma spectroscopy sample analysis did not require further investigation.

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. HTD analysis identified some radionuclides meeting the acceptance criteria for detection (i.e., a result greater than two 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.
One (1) biased sample was collected at a location selected by FSS Supervision based on professional judgment and observation.
Gamma spectroscopy analysis was performed by the off-site laboratory to the required MDC. The detectable radionuclide concentrations were a very small fraction of the Operational DCGL. No further action or investigations were required.
A summary of the sample results is provided in Table 8.

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 split results at location 9512-0000-017F/FS.
The other split sample, 9512-0000-014F/FS, K-40, a natural radioisotope, was found to be present at acceptable level of agreement, therefore, the comparison was determined to be acceptable. There was no Cs-137 to compare in this sample.
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 during the implementation of FSS in this survey unit. Consequently, no investigations were required.
- 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.
- 10.
CHANGES FROM THE FINAL STATUS SURVEY PLAN Three (3) of the systematic samples (samples 9512-0000-008F/FS, 9512-0000-011F and 9512-0000-012F) initially identified for non-parametric testing fell outside of the survey unit. The initial design of the survey unit included area that was not within the property boundary. This was discovered during the implementation of the FSSP. Three additional random samples were selected for non-parametric testing, in accordance with Addendum 1 of the FSSP.
The random samples were numbered 9512-0000-017F/FS, 9512-0000-018F and 9512-0000-019F.

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 3.
The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). See Table 9.
Table 9 -

1.60E-01 Standard Deviation:
2.06E-01 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.

SURVEY UNIT 9512-0000 RELEASE RECORD The range of the data is approximately 2.98 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 0.859.
All data, assessments, and graphical representations are provided in.

ANOMALIES No anomalies were noted in the performance of this FSS.
- 13.
CONCLUSION Survey Unit 9512-0000 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. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. The survey unit was properly designated as Class 3.
The soil of this survey area meets the requirements for unrestricted release as a Class 3 survey unit under the criteria and requirements of the HNP License Termination Plan (LTP).
The dose contribution from soil is 0.50 mrem/yr TEDE based on the average concentration of the samples used for non-parametric statistical sampling.
This survey unit is affected by existing groundwater (reference CY memo ISC 06-024). The dose contribution from existing groundwater is two (2) mrem/yr TEDE.
This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no 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.
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 is 2.5 mrem/yr TEDE. Therefore, Survey Unit 9512-0000 is acceptable for unrestricted release.

h Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.
- Indicates analyte is a surrogate compound.
A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.
For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.
