SURVEY UNIT DESCRIPTION Survey Unit (SU) 9525-0000, (Southeast Site Road) is designated as Final Status Survey (FSS) Class 3 and consists of approximately 3,556 m 2 (0.88 acres)section of asphalt-paved road with a steep grade located east of Haddam Neck Plant (HNP) site industrial area. The road area selected for the survey unit is approximately 1,400 meters in length, 2.5 meters wide, and runs in a north-south direction.

To the north, the road extends into adjacent property owned by Connecticut Light and Power Company. To the south, the road runs towards the Discharge Canal connecting with the Haul Road running along the canal. The boundaries for the survey unit start at the property owner demarcation near an electrical substation located east of the HNP, extends from side to side of the road, then terminates about 1,400 meters down the road-south, perpendicular from the northeastern boundary of Survey Unit 9521-0000.

On the west, Survey Units 9526-0000, and 9526-0001 bound 9525-0000.

On the east, Survey Units 9532-0000 and 9528-0000 bound the unit. The adjacent area topography ranges from flat areas to steep hillsides that are heavily wooded and overgrown with brush.The reference coordinates associated with SU 9525-0000 are E057 through E020 by S061 through S083 (see License Termination Plan 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).The historical files indicate that at one time, the public was allowed to use the road to access the canal for recreational fishing purposes.

The area was heavily used by the public and debris piles consisting of old cans and bottles can still be found in some areas, mainly along the canal, from this time period.Survey Unit 9525-0000 is a "closed to the public," utility-access road exhibiting typical features.

The road was repaved in the past and patched in areas where degradation has occurred.

An inspection to support the Independent Spent Fuel Storage Installation (ISFSI) project indicated that the asphalt thickness ranged from 1.5" to 5" (3.5 -12 cm). The road will be used after final status survey completion.

2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10,"Survey Unit Classijcation." The historical information and scoping results provide sufficient data to designate SU 9525-0000 as Class 3 in August 2001.The "Classijcation Basis Summary" conducted for SU 9538-0000 consisted of: a) A review of the 1OCFR50.75 (g) (1) database, Revision 1 3 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD b) A review of the "Initial Characterization Report" and "Historic Site Assessment Supplement, " c) Historic and current survey records review, d) Personal interviews, e) Visual inspections and a "walk down." A review of the lOCFR50.75 (g) (1) database report identified one document associated with this survey area. Plant Incident Report (PIR) 80-37 describes the discovery of radioactive particles found on the hillside and other areas of the site. The investigation into the incident concluded that the particles were most likely ejected from the primary vent stack as a result of several operational events in 1979. Isotopic analysis of the particles indicated that the short-lived fission products Ce-144 and Ru-106 dominated the particle radioactivity.

A comprehensive survey was performed in 1980 had identified contamination on the east hillside from the RCA boundary out to a distance of 200 meters.Following identification of the contamination, further surveys were conducted to a distance of 400 meters, with no additional plant related radioactivity identified.

A review of historic information indicates that the road was surveyed as part of this survey effort. No contamination was found on the Southeast Site Road.A review of the "Initial and Supplemental Characterization Reports " as well as the previous "Classifi cation Basis Sunmmaries" provided no additional information pertinent to classification.

A review of soil relocation files show that the road was resurfaced in 1985.There is no information indicating that impacted soil was mixed prior to paving.A Survey Sampling Work Plan (SSWP N2. BCY-SSWP-03-04-002) was developed and implemented during April 2003 to obtain the necessary data of sufficient data quality for Final Status Survey (FSS) planning purposes.Samples were taken of the asphalt and the underlying soil (i.e., soil under the asphalt).

Six (6) data points were used to determine the radiological concentration variability in this survey unit. No plant-related radioactive material was found in either the asphalt or the underlying soil other than low-levels of Cs-137, which was only identified in two (2) of the six (6) underlying soil samples. The reported Cs-137 analysis results for the six (6) asphalt samples show a mean concentration of 0.013 pCi/g, maximum concentration of 0.0197 pCi/g and standard deviation for sample measurements of 0.005746 (see Table 1). The concentrations of Cs-137 found in the underlying soil were well below those concentrations determined from off-site locations as documented by Health Physics Technical Support Document (TSD) BCY-HP-0063,"Background Cs-137 Concentration in Soil." Given the age and past use of the road, it is unlikely that the underlying soils will contain residual radioactivity associated with plant operation.

0.006 Personnel interviews were conducted with CYAPCO personnel to ascertain when the road had originally been constructed and paved. Unfortunately, the individuals surveyed could not recall the date or time period. These individuals did recollect that CY permitted fisherman access to the Discharge Canal in the past. Several documents support this assertion and provide ample proof that the canal was receiving steady traffic from local fisherman.

Historic documents and photos point to the period between 1968 and 1971 as a potential starting point for the construction of the road. Although the photo clarity cannot confirm paving, it would seem practical to pave the road, especially near the substation, to minimize erosion and precipitation run-off.The Site Radiological Release Supervisor performed a "walkdown" of the area prior to classification.

The Southeast Site Road is a paved road with a relative steep grade. A review of the soil relocation files shows that the road was resurfaced in 1985. An inspection of road modification work to support the ISFSI project indicates that the asphalt thickness ranges from 1.5" to about 5".Several locations show evidence of localized asphalt "patching", which was probably performed in the past to repair the road.At the time of FSS, the dose impact from groundwater contamination was not considered.

The classification basis shows that the expected residual radioactivity in the survey unit would be below the site remediation criteria and are consistent with procedural guidance, thereby sufficient to justify final designation as Class 3.3. DATA QUALITY OBJECTIVES (DQO)The primary objective of the Final Status Survey Plan (FSSP) was to demonstrate that the level of residual radioactivity in Survey Unit 9525-0000 did not exceed the release criteria specified in the License Termination Plan (LTP), was below the 10 mrem/yr Administrative Level Derived Concentration Guideline Level (DCGL), and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).FSS design and planning endorsed the use of 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 Revision 1 5 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD 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 satisfy the release criteria objective of the FSS.The DQO process determined that Cs-137 would be the radionuclide of concern during the 9525-0000 FSS process. Additionally, to provide conservatism, the Base Case DCGLs for radionuclides in soil was reduced by 60% to establish the Administrative Level DCGL.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 performed before issue and after the instrument had been used. Control and accountability of survey instruments were maintained to assure the quality and prevent the loss of data.Laboratory DQOs and analysis results were reported as actual calculated results.Results reported as less than Minimum Detectable Concentration

(<MDC)would not be accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result and uncertainty of two standard deviations (2a), laboratory data qualifiers, units and the required and observed MDC (see Table 2).Revision I 6 Revision 1 6 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD Table 2 -FSS DCGL Values and Required Minimum Detectable Concentrations Radionuclide Base Case Soil Administrative Level Required MDC DCGL (pC[/g) (') DCGL (pCi/g) (2) Wpi/g) (3)H-3 4.12E+02 1.65E+02 1.65E+01 C-14 5.66E+00 2.26E+00 2.26E-01 Mn-54 1.74E+01 6.96E+00 6.96E-01 Fe-55 2.74E+04 1.IOE-+04 1.1OE+03 Co-60 3.81E+00 1.52E+00 1.52E-01 Ag-108m 7.14E+00 2.86E+00 2.86E-01 Ni-63 7.23E+02 2.89E+02 2.89E+01 Sr-90 1.55E+00 6.20E-01 6.20E-02 Nb-94 7.12E+00 2.85E+00 2.85E-01 Tc-99 1.26E+01 5.04E+00 5.04E-01 Cs-134 4.67E+00 1.87E+00 1.87E-01 Cs-137 7.91E+00 3.16E+00 3.16E-01 Eu-152 1.O1E+O1 4.04E+00 4.04E-01 Eu-154 9.29E+00 3.72E+00 3.72E-01 Eu-155 3.92E+02 1.57E+02 1.57E+O1 Pu-238 2.96E+01 1.18E+01 1.18E+O0 Pu-239/240 2.67E+01 1.07E+01 1.07E+O0 Pu-241 8.70E+02 3.48E+02 3.48E+01 Am-241 2.58E+01 1.03E+01 1.03E+OO Cm-243/244 2.90E+01 1.16E+01 1.16E+OO (1) The Base Case DCGLs for soil are specified by the LTP in Chapter 6.(2) The Administrative Level DCGL is 40% of the Base Case DCGL.(3) The required MDC was 10% of the Administrative Level DCGL.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. To assist the Final Status Survey Engineers when preparing survey plans for FSS, guidance is provided in Procedure RPM 5.1-11. By design, the FSSP meets the ALARA criteria for soils as specified in Chapter 4 of the LTP.The LTP specifies that the selection of the scan area size is judgmental for Class 3 areas. The fraction of scanning coverage was determined during the DQO process with the total amount, and location(s) based on the likelihood of finding elevated activity during FSS. The historic data supported the decision to scan 186.7 m 2 of 9525-0000.

The selection of two (2) land areas, Scan Areas 1 and 2 were based on the inspection tour of the area. These areas are located at corners of the road where collection of residual radioactivity is probable.

One of the scan areas is the nearest point on the Southeast Access Road relative to the Radiation Controlled Area of HNP (distance 0.22 miles). Elevated areas of Revision 1 7 Revision 1 7 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD residual radioactivity were not considered likely based on Historical Site Assessment data and survey unit inspection tours. Scan Area 1 is approximately 62.25 m 2 and Scan Area 2 is 124.4 m 2.Scans were also prescribed for a one (1)meter radius around each random and biased Sample Measurement Location (SML).Six (6) data points were used to determine the radiological concentration variability in this survey unit. The population data set included data from this SU collected during scoping and characterization.

Radionuclide-specific analyses of soil samples collected from this survey unit and adjacent land areas with similar history and physical characteristics have identified only a few radionuclides, principally Cs-137. The data collected prior to FSS indicated that the remaining radionuclides listed in Table 2 would not be present in quantities greater than 5% of the applicable Base Case DCGL in this survey unit at the time of FSS. It was unlikely that the aggregate concentration of the remaining radionuclides would exceed 10%; therefore, only Cs-137 was used in the survey planning of SU 9525-0000.

The use of the 5% and 10% rule is consistent with the development of surrogate ratio DCGLs as described in the LTP.The DQO process determined that Cs-137 would be the radionuclide of concern during the 9525-0000 FSS process. The Operation DCGL of 3.16 pCi/g for Cs-137 was used to demonstrate compliance with the release criteria.Surrogate DCGLs are not required for this survey unit because of the radionuclide specific analysis and radionuclide de-selection in accordance with the 5% and 10% rule.The Elevated Measurement Comparison (EMC) does not apply to this survey unit since discrete, elevated areas of contamination are 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.The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Nuniber of Surface Samples for FSS. " Survey design specified fifteen (15) surface soil samples for the Sign Test non-parametric statistical testing.For the FSS, two (2) biased soil SMLs were selected in areas where contamination may collect, near corners and access/egress points along the road.Although Procedure RPM 5.1-11 only specified that 5% of the samples be selected for Hard-to-Detect (HTD) analysis, two (2) soil samples or 13% were randomly selected for HTD radionuclide analysis by using the Microsoft Excel "RANDBETWEEN" function.

Each sample would be sent for a full suite Revision I 8 Revision 1 8 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD analysis of the HTD radionuclides specified in the LTP, Table 2-12,"Radionuclides Potentially Present at Haddam Neck Plant." 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 "RANDBETWEEN" function.

The number of quality control soil samples was determined to be 13% of fifteen (15) samples, rounded up to the next whole number.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 FSS." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNNL) for the United States Department of Energy. Random grid spacing with a random starting point was selected for sample design, which is appropriate for a Class 3 area.Sample location and scan areas were identified using AutoCAD-LtD a commercially available plotting software with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample and scan locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 3.Table 3 -Sample Measurement Locations (SML) with Associated GPS Coordinates.

Revision 1 9 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD The Lower Bound of the Gray Region (LBGR) was adjusted in accordance with Procedure RPM 5.1-11 to 0.99 of the Operational DCGL to maintain the relative shift (A/a) in the range of I and 3. In a Class 3 survey unit the median concentration is expected to be below the LBGR, in which case a Prospective Power Curve would be unnecessary and was not generated.

The mean concentrations for Co-60 and Cs-137 identified during the scoping and characterization indicate this assumption to be true.Table 4 provides a synopsis of the survey design.Table 4 -S nopsis of the Survey Design Feature Design Criteria Basis Based on AutoCAD and Survey Unit Size 3,556.4 in 2 Visual Sample Plan calculations Type I (a) and Type II (1 were 0.05; relative shift Number of Measurements 15 (A/a) set at 2 by procedure, the LBGR at 0.99.Grid Spacing Random and Appropriate design for Class Random Start 3 Area...Not appropriate design for Interval Spacing Not Applicable assr3prandosampling Class 3 random sampling DCGL 3.16 pCi/g Operational DCGL applied DCGL _Cs-137 to field data (l)Based on likelihood of Scan Survey Coverage 186.7 m2 finding elevated readings in (5.5%) this particular Class 3 survey unit a i Detectable over Based on achieving the background Administrative Level DCGL (I) The Operational DCGL was based on achieving an administrative level that was 40%h of the soil DCGL and assuming no impact from radioactive contamination in groundwater or from buried concrete debris.5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 24265-000-GEN-0000-00144-000.

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.Revision I 10 Revision I 10 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD Survey activities occurred between April 30 and May 20,2003.The land areas, Scan Areas 1 and 2 were marked out using GPS coordinates consistent with the Connecticut State Plane System and scanned for elevated readings.

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.Using GPS coordinates, the SMLs were identified and marked with a surveyor's flag for identification.

At each SML, a one (1) meter radius around the sample flag was scanned for elevated radiation levels.Fifteen (15) surface soil samples were collected in random locations and packaged in accordance with HNP Procedure RPM 5.1-3, "Collection of Surface and Subsurface Soil, Shoreline Sediment, Asphalt and Liquid samples for Scoping, Characterization and Final Statuts 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 Scoping, Characterization and Final Status Samples. " Two (2) samples (009F and 012F) were randomly selected for HTD radionuclide analysis.Two (2) samples (002F and 006F) were collected for "split sample" analysis by the off site laboratory.

6. SURVEY RESULTS No elevated readings were identified during scanning the SMLs or in the Scan Areas (see Table 5). No further action or investigations were required.

The laboratory analyzed the fifteen (15)samples taken for non-parametric statistical testing, the associated duplicates and scan area samples using gamma spectroscopy.

Gamma spectroscopy analysis was performed to the required MDC. Cesium-137 was the only gamma-emitting radionuclide detected at statistically significant concentrations.

In combination with the other detected nuclides (Cs-137), the maximum f-DCGL in the sample set was 0.385 of the Administrative Level DCGL (SML 009F).

Thirteen percent (13%) of the samples were selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using United States Nuclear Regulatory Commission (USNRC)acceptance criteria specified in Inspection Procedure 84750 as detailed in Procedure RPM 5.1-24. There was acceptable agreement between field split results. The sample analysis vendor, STL-Richland, Richland, Washington maintains quality assurance and quality control plans as part of normal operation.

Refer to Attachment 2 for data and data quality analysis results.8. INVESTIGATIONS AND RESULTS No investigations were performed as the result of FSS in Survey Unit 9525-0000.9. REMEDIATION AND RESULTS Historically, no remediation 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 Reniediation 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 The change made from the LTP, prior to this FSS, was a decrease in the concentrations for the Base Case DCGLsoil.

The LTP presents DCGLs that correspond to a Total Effective Dose Equivalent (TEDE) of 25 mrem/yr. This survey unit was evaluated against Administrative Level DCGLs that correspond to 10 mrem/yr.Revision 1 13 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD The required MDC for sample 009F HTD Sr-90 analysis could not be reasonably achieved.

The DQOs recognized that certain analytical methods might not meet MDC requirements (e.g., "high" radiation screening limitations).

The MDCs were set at 4% of the soil DCGL to be as far below the DCGL as practical.

In accordance with the LTP, a value at 10% of the soil DCGL would have been the desired level of sensitivity with up to 50% of the DCGL being acceptable.

Review of the data shows that the lab reported Sr-90 MDC was 50%below the maximum level of sensitivity specified by Section 5.5 of the LTP (i.e., <50% of the applicable soil DCGL) and are therefore acceptable.

Strontium-90 sample results were well above the reported MDC and considered valid.Vendor laboratory analysis for sample 009F used a smaller aliquot than required by the analytical method. The lab used a small aliquot due to a "high" radiation screen. Using a sample with a "high" screen would affect counting and analytical techniques if the normal sample aliquot were used. However, the laboratory control sample, batch blank, sample and sample duplicate results are within acceptance limits for the lab quality control.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. All sample results were less than the release criteria.

Therefore, the Sign Test shows that the survey unit passes Final Status Survey.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 converting the data into units relative to the release criteria (i.e., pCi/g) and calculating basic statistical quantities (e.g., mean, median, standard deviation).

The initial data review consisted of reviewing the analytical data for the fifteen (15) asphalt samples and comparing results to the reported and required MDC.The values for Cs-137 were below the laboratory reported MDC and well below required MDC. Sample 9525-0000-009F was considered as a "positive" result for Cs-137, exceeding two standard deviations (2ca). The highest calculated fraction of the DCGLc.1 3 7 for this sample was 1.5%.Revision I 14 Revision 1 14 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD The range of the data was about one standard deviation (lIa). The difference between the mean and median was 3.25% of the standard deviation.

The data is slightly skewed positive.

An increase in the variability was indicated by the fact that the standard deviation was greater than design. This expected increase results from more locations being sampled, thus affecting the variability.

The data was represented graphically through posting plots, a frequency plot and a quantile plot. When the data is displayed in a cumulative frequency distribution, the data is distributed around the low mean concentration of 0.00729 pCi/g Cs137. This distribution is typical of an area with very low to no detectable levels of contamination.

All data, assessments and graphical representations are provided in Attachment 2.12. ANOMALIES All data is considered valid including negative values, zeros, values reported below the MDC and values reported with uncertainties greater than standard deviations(2a)

.Some radionuclides have been reported at low concentrations that are statistically significant at the 95% confidence level, but with a relatively high level of uncertainty.

Gamma spectroscopy results identified several radionuclides meeting the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty

-2a). Cesium-134 and Am-241 were frequently identified in sample results. The offsite laboratory data qualifier unit shows that these radionuclides were analyzed for and the result was less than the MDC. These very low-level"detections" may be attributed to false positive noise at the lower limit of the measuring technique.

Hard-to-Detect analyses results identified Sr-90 in sample 9525-0000-012F as meeting the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty-2a).

However, the reported laboratory blank Sr-90 value for this sample was 10% greater than the analytical results. When compared, the sample statistical values are almost identical to the blank values (results, count error, MDC, and yield). This very low-level "detection" may be attributed to false positive noise at the lower limit of the measuring technique and analytical uncertainty.

The Sr-90 value compares favorably with research conducted in other regional areas concerning fallout resultant from nuclear testing in the past as referenced in EPRI Technical Report 1003030,"Determining Background Radiation Levels in Support of Decommissioning Nuclear Power Plants. " These HTD radionuclides do not represent quantities that would increase the requisite number of samples for non-parametric statistical sampling or cause the survey unit to fail to meet the release criteria.

Sample analysis did not indicate any anomalies requiring further investigation.

Revision 1 15 Revision 1 15 SOUTHEAST SITE ROAD SURVEY UNIT 9525-0000 RELEASE RECORD 13. CONCLUSION Survey Unit 9525-0000 has met the DQOs of the Final Status Survey. For this survey unit, the ALARA criteria for soils as specified in Section 4 of the LTP was achieved.

Elevated Measurement Comparison and remediation was not required.The sample data passed the Sign Test. The null hypothesis was rejected.Evaluation of the data shows that none of the FSS design radionuclides or HTD soil concentration values exceeded the Operational DCGL or unity. No large anomalies were observed in the graphical representation of the data. The survey unit was properly designated as Class 3. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved.This survey unit is not considered impacted by radioactive contamination in groundwater based on location, topography and current hydro-geologic sampling data as referenced in Health Physics TSD CY-HP-0193, "Assessment of Existing Groundwater Dose for Phase II Release Areas of the Final Status Survey Report.

• .r Uncertainty Estimation STL Richland has adopted the internationally accepted approach to estimating uncertainties described in "NIST Technical Note 1297, 1994 Edition".

The approach, "Law of Propagation of Errors", involves the identification of all variables in an analytical method which are used to derive a result. These variables are related to the analytical result (R) by some functional relationship, R -constants

• (x,yz,...).

The components (x,yz) are evaluated to determine their contribution to the overall method uncertainty.

The individual component uncertainties (u) are then combined using a statistical model that provides the most probable overall uncertainty value. All component uncertainties are categorized as type A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the components, such as sample homogeneity, are combined with the component uncertainty as the square root of the sum-of-the-squares of the individual uncertainties.

The uncertainty associated with the derived result is the combined uncertainty (u) multiplied by the coverage factor (1,2, or 3).When three or more sample replicates are used to derive the analytical result, the type A uncertainty is the standard deviation of the mean value (S/vn), where S is the standard deviation of the derived results. The type B uncertainties are all other random or non-random components that are not included in the standard deviation.

The derivation of the general "Law of Propagation of Errors" equations and specific example are available on request STL Richland-. _.STL RICHILND 5 Report Definitions.-.

Analytical Results/Metliodology The analytical results for this report are presented by laboratory sample ID. Each set of data includes sample identification information, analytical results and the appropriate associated statistical errors.The requested analyses were: Alpha Spectroscopy Americium-241 by method RICH-RC-5080 Curium-243/244 by method RICH-RC-5080 Plutonium-238, -239/240 by method RICH-RC-5010 Gas Proportional Counting'Strontium-90 by method RICH-RC-5006 Severn Trent Laboratories, Inc.3 STh RICHLAND Connecticut Yankee Atomic Power Company March 16,2004 Page 2 Liquid Scintillation Counting Carbon-14 by method RICH-RC-5022 Iron-55 by method RICH-RC-5074 Nickel-63 by method RICH-RC-5069 Plutonium-241 by method RICH-RC-5010 Technetium-99 by method RICH-RC-5078 Tritium by method RICH-RC-5037 Gamma Spectroscopy Gamma by method RICH-RC-5017 IV. Quality Control The analytical result for each analysis performed includes a minimum of one laboratory control sample (LCS), and one reagent blank sample analysis.

Any exceptions have been noted in the "Comments" section.QC and sample results are reported in the same units.V. Comments Americium-241 by method RICH-RC-5080:

Sample 9525-0000-012F failed due to a low tracer recovery of 4%. The sample will be reanalyzed and reported upon completion.

Except as noted, the LCS, batch blank, sample and sample duplicate results are within acceptance limits.Curium-243/244 by method RICH-RC-5080:

Sample 9525-0000-012F failed due to a low tracer recovery of 4%. The sample will be reanalyzed and reported upon completion.

Except as noted, the LCS, batch blank, sample and sample duplicate results are within acceptance limits.Plutonium-238.

-239/240 by method RICH-RC-5010:

The LCS, batch blank, sample and sample duplicate results are within acceptance limits.Strontium-90 by method RICH-RC-5006:

Sample 9525-0000-009F MDA does not meet the CRDL. A small aliquot was taken due to a high radiation screen. Except as noted, the LCS, batch blank, sample and sample duplicate results are within acceptance limits.Carbon-14 by method RICHI-RC-5022:

The LCS, batch blank, sample and sample duplicate results are within acceptance limits.4 STL RICHLAND Connecticut Yankee Atomic Power Company March 16,2004 Page 3 Iron-55 by method RICH-RC-5074:

Samples 9525-000-09F has a tracer yield of 138% due to matrix effect (indigenous iron in the soil). Except as noted, the LCS, batch blank, sample and sample duplicate results are within acceptance limits.Nickel-63 by method RICH-RC-5069:

The LCS, batch blank, sample and sample duplicate results are within acceptance limits.Plutonium-241 by method RICH-RC-5010:

The LCS, batch blank, samples and sample duplicate results are within acceptance limits.Technetium-99 by method RICH-RC-5078:

The LCS, batch blank, samples, sample duplicate and are within acceptance limits.Tritium by method RICH-RC-5037:

Samples 9538-0000-01 iF and 9538-0000-012F01 were previously dried in order to run the gamma analysis therefore the H-3 analysis is unable to be run. Sample 9525-0000-09F and 9525-0000012 F are asphalt samples and were therefore leached with dead water and the dead water was counted for I1-3. The LCS, batch blank, sample and sample duplicate results are within acceptance limits.Gamma by method RICH-RC-5017:

The samples that were requested to be analyzed as four separate samples were previously dried, ground, and analyzed as two samples. There was no way to analyze these samples as four separate samples therefore the gamma analysis was not run.I certify that this Certificate of Analysis is in compliance with the SOW, both technically and for completeness, for other than the conditions detailed above.

Uncertainty Estimation STL Richland has adopted the internationally accepted approach to estimating uncertainties described in "NIST Technical Note 1297, 1994 Edition.'

The approach, 'Law of Propagation of Errors", involves the identification of all variables in an analytical method which are used to derive a result. These variables are related to the analytical result (R) by some functional relationship, R = constants

• f(xyz,...).

The components (xyz) are evaluated to determine their contribution to the overall method uncertainty.

The individual component uncertainties (ua) are then combined using a statistical model that provides the most probable Vverall uncertainty value. All component uncertainties are categorized as type A. evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the components, such as sample homogeneity, are combined with the component uncertainty as the square root of the sum-of-the-squares of the individual uncertainties.

The uncertainty associated with the derived result is the combined uncertainty (uj) multiplied by the coverage factor (1,2, or 3).When three or more sample replicates are used to derive the analytical result, the type A uncertainty is the standard deviation of the mean value (S/vn), where S is the standard deviation of the derived results. The type B uncertainties arc all other random or non-random components that are not included in the standard deviation.
