SOUTHERN END OF PENINSULA SURVEY UNIT 9531 -0000 RELEASE RECORD SURVEY UNIT DESCRIPTION Survey Unit 9531-0000 (Southern End of Peninsula) is designated as Final Status Survey (FSS) Class 3 and consists of 108,222 m2 (26.8 acres) of uninhabited open land located approximately 0.77 miles from the reference coordinate system benchmark used at Haddam Neck Plant (HNP) (see , Figure 1). The area is mostly wetlands and wooded lowlands with large clumps of heavy brush. The topography of the southern portion of the peninsula is somewhat flat with sloping banks to the Discharge Canal and Connecticut River. The soil is mostly sand and the area is covered with dense grass or brush with some spots being heavily wooded. Survey Unit 9531-0000 is bounded on the east by the Discharge Canal, on the south and west by the Connecticut River, with a portion of Survey Area 9530 bounding the north perimeter. A small pond is contained in the interior of the survey unit. An old roadway allows for access to the end of the peninsula.

The reference coordinates associated with this survey unit are E020 through E008 by S125 through S160 (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).

There are no known events potentially impacting this survey unit. The historical files indicate that there was evidence of past soil disturbance in this survey unit as indicated by mounds along the roadway. There was also evidence of past use of the peninsula for recreational use (e.g., fishing) and there is debris along the bank and in the lowland area adjacent to the Connecticut River.

There are several standing, capped pipes in the survey unit indicating that test wells were sunk sometime in the past. The objective and date of installation could not be established. There is a ten inch (10") capped metal pipe in the interior of this survey unit. A review of site drawings (Property Plan 10899-FX-IR) show this to be an old industrial well sunk in 1963 by the S. B. Church Company. A discussion with a contract hydro-geologist indicates that this well was never used due to insufficient well yield.

In Section 5.4.7.1 of the LTP, Equation 5-1 expresses the total dose contribution from three (3) components; soil contribution, existing groundwater contribution and future groundwater contribution. The survey data results for this release record address the dose contribution due to soil as provided in LTP Equation 5-

1. This survey unit is not considered impacted by existing groundwater radioactive contamination as the survey unit is outside the capture zone perimeter for an affected monitoring well. The dose contribution from existing groundwater, the second component of Equation 5-1, is therefore zero. This survey unit is not considered impacted by future groundwater radioactive contamination, as there are no underground structures, systems or components Revision 0 3

SOUTHERN END OF PENINSULA SURVEY UNIT 953 1-0000 RELEASE RECORD containing residual radioactive material within the groundwater saturated zone in the area. The dose contribution from future groundwater, the third component of Equation 5-1, is therefore zero.

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 9531-0000 as Class 3 in August 2001.

The "Classification Basis Summary" conducted for Survey Unit 9531-0000 consisted of:

a) A review of the I0CFR50.75 (g) (1) database, b) A review of the "Initial CharacterizationReport " and the "HistoricSite 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 identifies seven (7) documents associated with or relating to this survey area.

a) Event PIR 80-37: Contamination was documented to be present in an area outside the restricted area. Small areas of low-level contamination were found on the facility grounds through routine survey in a normally non-radioactive area. The areas were cleaned up in 1980. The records show that no contamination was found in 953 1-0000.

b) Radiological Assessment Branch (RAB) memo NE-86-RA-1 142 (November 1986): Radiological analysis of the Discharge Canal.

Memo discusses dredging the Discharge Canal and identifies a proposed location for the dredge spoils. The storage location for these dredged materials was a disposal area with sloping berm located in an adjacent Survey Area 9530. NE-86-RA-1 142 is not directly associated with Survey Area 9531, however, related documents (e.g., NE-86-L-1229) and drawings indicate that approximately 12,000 cubic yards of dredged materials from 1979 were removed from the disposal area and spread over the peninsula in nearby Survey Unit 9530-0004.

c) Condition Report (CR) 02-0133 identified three (3) rusty drums that were found on the peninsula during scoping surveys. These barrels were surveyed for radioactivity and meet the release criteria.

d) Condition Report (CR) 02-0185: gamma spectroscopy reported a Co-60 result meeting the accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty). The identification of more plant-related radioactivity led to a shift of the survey area boundary to remove approximately two (2) acres from survey area 9531. The two Revision 0 4

SOUTHERN END OF PENINSULA SURVEY UNIT 953 1-0000 RELEASE RECORD (2) acres were included in adjacent survey area 9530 which already contains several survey units with the potential to contain plant-related radioactivity.

e) Condition Report 03-1020: Unusually high rainfall and tide have introduced Discharge Canal water into the middle of the peninsula.

Subsequent surveys did not identify significant change from the FSS results.

f) Condition Report 04-0456: Unusually high rainfall and tide have introduced Discharge Canal water into several areas including the peninsula. Subsequent surveys did not identify a significant change from the FSS results.

g) Memo ISC 05-045: Periodic surveillance following final status survey.

Surveillance is required periodically by the LTP to ensure the radiological condition does not significantly change from the FSS results. The memo documents no negative change in the radiological status.

A review of the "Initialand Supplemental CharacterizationReports" as well as the previous "Classification Basis Summaries" provided no additional information pertinent to classification.

A characterization survey plan was initiated and executed by Site Closure personnel in March and April 2002 to determine existing conditions and obtain radiological data for Final Status Survey (FSS). Radiological results from the recent surveys indicated that plant related radioactive materials in soil (e.g., Co-60) were below the Minimum Detectable Activity (MDA). No areas of elevated radioactivity were identified in the survey unit.

Eighteen (18) samples were taken initially in accordance with the plan. Of the 18 samples initially taken, seventeen (17) sample results were used to determine the variability of radioactivity concentrations in this survey unit.

The identification of Co-60 meeting the accepted criteria for detection in the remaining sample led to an investigation, the identification of more Co-60 and ultimately a shift of the survey unit area boundary to remove approximately two (2) acres from Survey Unit 9531-0000 into adjacent survey units. Table 1 provides an overview of the statistical quantities from the seventeen (17) samples taken during the survey. The Co-60 reported results did not meet the accepted criteria for detection in this set of samples.

Minimum Value: 2.1 OE-02 Maximum Value: 2.72E-01 Mean: 1.32E-01 Median: 1.41E-01 Standard Deviation: 6.98E-02 The FSS Engineer performed several visual inspections and walkdowns during 2002 to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions.

Assessment of the groundwater impact is discussed in Section 1 and Section 13.

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 the final designation as 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, "Preparationof FinalStatus 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 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 might 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 9531-0000 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).

Revision 0 6

SOUTHERN END OF PENINSULA SURVEY UNIT 9531 -0000 RELEASE RECORD 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 Values (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 additional future groundwater radioactivity from building basements and footings.

A reduction to the Base Case Soil DCGLs provided in Chapter 6 of the LTP must be performed to ensure compliance with the release criteria of twenty-five millirem (25 mrem) in a year Total Effective Dose Equivalent (TEDE) when all three pathways (soil, existing groundwater and future groundwater) are potentially present. Chapter 5 of the LTP shows a compliance formula, Equation 5-1, for including the total dose from the three media. The reduced DCGL is called the Operational DCGL whose relationship to the Base Case Soil DCGL is shown by Equation 5-3 of the LTP. The Base Case Soil DCGL for Cs-137 and the DCGLs for all the other radionuclides potentially present in soil were administratively reduced by about 60% to ensure compliance with the 25 mrem in a year TEDE criterion (Table 2).

Seventeen (17) samples were collected and analyzed during characterization as discussed in Section 2.

The samples were collected through biased sampling over a simple grid design.

Characterization did not include analyses for Hard to Detect (HTD) radionuclides as data from previous survey and sampling in adjacent areas did not identify HTDs in significant quantities. Cesium-137 was found to be the predominate radionuclide of concern. The mean and variability of Cs-137 in 953 1-0000 was determined during characterization.

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 to be performed before issue and after the instrument had been used. Control and accountability of survey instruments was to be maintained to assure the quality and prevent the loss of data.

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. To assist the FSS Engineers when preparing survey plans for FSS, guidance is provided in Procedure RPM 5.1 -11, "Preparationof Final Status Survey Plans". By design, the FSSP meets the ALARA criteria for soils as specified in Chapter 4 of the LTP. The FSSP uses an integrated sample design that combines scanning surveys and sampling which can be either random or biased.

Seventeen (17) data points from characterization were used to determine concentration variability. The samples were collected through biased sampling over a simple grid design. The DQO process determined that Cs-137 would be the radionuclide of concern in 9531-0000 (refer to Section 3). The Operational Revision 0 8 Revision 0 8

SOUTHERN END OF PENINSULA SURVEY UNIT 9531-0000 RELEASE RECORD DCGL of 3.16 pCi/g for Cs-137 was to be used to ensure compliance with the release criteria. Other radionuclides identified during FSS would be evaluated to ensure adequate survey design.

Surrogate DCGLs were not required for this survey unit because of process knowledge from characterization of nearby adjacent areas and via screening under LTP Section 5.4.7.2. 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 discrete, elevated areas of contamination 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.

The number of soil samples for FSS was determined in accordance with Procedure RPM 5.1-12, "Determination of the Number of Surface Samplesfor FinalStatus Survey. " The Lower Bound of the Gray Region (LBGR) was set in accordance with Procedure RPM 5.1-11 to 3.02 pCi to maintain the relative shift (A/a) in the range of I and 3. 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. Survey design specified fifteen (15) surface 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 systematic triangular 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 number of judgmental samples represented 80% of the number of samples that would be used for non-parametric statistical testing.

Although Procedure RPM 5.1-11 only specified that 5% of the samples be selected for HTD analysis, two (2) soil samples, or 13% 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 would be 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."

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 LTP specifies that scanning will be performed in judgmental measurements for a Class 3 land area and cover a selected amount of the area. 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. Elevated areas of residual radioactivity were not considered likely based on characterization data. Consequently, the decision was made to scan Revision 0 10

SOUTHERN END OF PENINSULA SURVEY UNIT 953 1-0000 RELEASE RECORD slightly less than 1% of the total area. Scans were also prescribed for a one (1) meter radius around each random and biased sample measurement location.

For this Class 3 survey unit, the "Investigation Level" for area scanning and soil sample measurement results are those levels specified in LTP, Table 5-8, "Investigation Levels."

5. SURVEY IMPLEMENTATION Final status survey field activities were conducted under Work Plan and Inspection Record (WP&IR) 24265-000-GEN-0000-00107-000. 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.

Survey activities occurred August 19, 2002 through October 21, 2002.

The scan areas were marked out and scanned for elevated readings (see Attachment 2 for Scan Area Results). Scanning was performed with an Eberline E-600 using a SPA-3 sodium iodide detector. The E-600 was operated in the rate-meter mode and used with audio response. The probe was positioned as close to the ground as possible and was moved at a scan speed of about 0.5 meters per second. A little less than 1% of the survey unit was scanned.

Revision 0 I1I

SOUTHERN END OF PENINSULA SURVEY UNIT 9531 -0000 RELEASE RECORD Using GPS coordinates; sample measurement locations were identified and marked with a surveyor's flag for identification. At each sample measurement location, a one (1) meter radius around the sample flag was scanned for elevated radiation levels.

Fifteen (15) surface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Media for Final Status Survey" and FSS design. Samples were controlled, transported, stored, and transferred to the off-site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custodyfor FinalStatus Survey Samples. "

Two (2) samples (9531-000-013F and 9531-0000-015F) were randomly selected for HTD radionuclide analysis by the off-site laboratory.

Fifteen (15) biased soil samples (were collected and analyzed using gamma spectroscopy by the on-site laboratory.

The implementation of survey specific quality control measures included the collection of two samples (9531-0000-002F and 9530-0000-008F) for "split sample" analysis by the off-site laboratory.

6. SURVEY RESULTS The twenty-seven (27) sample measurement locations identified in the FSS plan were scanned about a one (1) meter radius for elevated radiation levels. Table 5 provides an overview of the scan area survey. Scan area results are provided in Attachment 2.

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 accepted criteria for detection (i.e., a result greater than two standard deviations uncertainty). All but one (1) radionuclide could be deselected or excluded using the 5% and 10%

rule described in Section 4. The exception was Cs-134 which was reported in one (1) sample at a concentration equivalent to 6% of the Operational DCGL.

Further explanation of Cs-134 will be provided in Section 10.

Cesium-137 was identified in fourteen (14) of the fifteen (15) samples. Cobalt-60 was identified in one (1) of the fifteen (15) samples. The mean of the results of gamma spectrometry analysis for each of the samples indicated Cs-137 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.

Sample analysis did not indicate any anomalies requiring further investigation.

A summary of the sample results is provided in Table 7.

All analyses met the required MDC with the exception of Sr-90. However, the DQOs recognize that for some HTD analyses, the radionuclides may not meet MDC requirements due to analytic method (e.g., Carbon-14 in soil). In these cases, comparison to a higher value (i.e., 50% of the DCGL) is acceptable and consistent with the LTP.

7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopy analysis. Thirteen percent (13%) 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 Assessmentfor Final Status Survey." There was acceptable agreement between field split results.

The sample analysis vendor, Severn Trent Laboratories - STL Richland, Richland, Washington, maintained 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 Additional scanning was performed in one (1) small location in February 2006 to obtain additional data relevant to the DQOs. The scanning was performed in a single three foot (3 ft) by thirty foot (30 ft) strip located in scan area 2. No elevated readings were identified.

Additional soil sampling was performed under an Addendum to the FSS plan.

The soil was collected from locations 13 and 15 to support HTD analyses after it was identified that the laboratory had prematurely dried the original sample material prior to determining what the required analyses were to be. The two samples were identified as 9531-0000-013AF and 9531-0000-015AF. The off-site laboratory properly processed and analyzed the additional samples for HTD.

Eight (8) localized areas were found to verifiably exceed their investigation level during the scan area survey. Two (2) samples were collected from each location. The samples consisted of a surface sample collected in a I L marinelli container at depths up to 15 cm and deeper samples collected in a I L marinelli container at depths up to 90 cm from the same sample location. The samples were analyzed on-site using gamma spectroscopy. The analyses reported Cs-137 as shown in Table 10.

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, "ALARRA Evaluation of Soil Remediation in Support of Final Status Survey," determined that remediation beyond that required to meet the release criteria was unnecessary and that the remaining residual radioactivity in soil was ALARA.

10. CHANGES FROM THE FINAL STATUS SURVEY PLAN Several HTD radionuclides were reported in concentrations exceeding the 5%

and 10% rule for de-selection. Therefore, the individual Operational DCGLs for these radionuclides were included into sample design to demonstrate compliance with the unity rule and ensure adequate survey design in accordance with the DQOs. The result of the COMPASS computer run showed adequate power for the revised survey design. The revised survey design maintained the original fifteen (15) surface soil samples for non-parametric statistical testing.

Cesium-134 was reported in concentrations exceeding the 5% rule for de-selection in one sample. A review of the data shows that the ratios of Cs-134 concentration to Cs-137 concentration are low enough not to impact or change the number of samples needed to demonstrate compliance with the DQOs.

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).

The range of the data, about 3.7 standard deviations, was not unusually large.

The difference between the mean and median was 15% of the standard deviation. The difference is enough to indicate skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot shows slight negative skewness as confirmed by the calculated skew of 0.5 and some bimodality probably due to the differences in terrain.

All data, assessments, and graphical representations are provided in Attachment 2.

12. ANOMALIES No anomalies were noted.

13. CONCLUSION Survey Unit 9531-0000 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 was not required.

The sample data passed the Sign Test. The null hypothesis was rejected. Some anomalies were observed in the graphical representation of the data which could be attributed to differences in terrain. The Retrospective Power Curve generated using COMPASS shows adequate power was achieved. The survey unit was properly designated as Class 3.

As discussed in Section 1, the survey data results for this release record address the dose contribution due to soil as provided in LTP Equation 5-1. This survey unit is not considered impacted by existing groundwater radioactive contamination as the survey unit is outside the capture zone perimeter for an affected monitoring well. The dose contribution from existing groundwater, the second component of Equation 5-1, is therefore zero. 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. The dose contribution from future groundwater, the third component of Equation 5-1, is therefore zero.

Uncertainty Estimation Sm Richland has adopted the Internationally accepted opproach to estimating uncertaInties described In -M ST Technical Note 1297, 1994 Edidon". The approach, 'Law af Prpagtlion of Errors",

Involves the kIdnification of all variables In an analytcal method which are used to derive a rsul. These variables gm related to the analytical msult (R) by some 1mclional retlaonsbipl R - constants 9 f(l;yz,.).

The components (xyz)aQe evaluated to determine teir contribution to die overall method uncertainty.

The Individual component uncertainties (u uam then combined using a statistical mode[ that provides the most probble overall unertainty value. All component uncertainties am categorized as tpe A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not incluoedel Inthecompoucats, suci as sample homognefty, in combined with the component uncuiranty u ho squae rot of ft sum-or-the-squarcs of the Individual uncertainties. Thc unecrtalnty associated with the derived result Is the combIn:d uncertainty (us multiptled by the caverage flctor (1CA o 3).

When three or more sample replicates am usstd to derive the analytical msult the tp A uncertainty Is the standard deviation ofthe mean value (St1), whero S is thc standard deviation ofthe derived results. The pe B uncertalnties ar all other random or non-random components that are not Included Inthe standard deviation.

m. Quality Control The analytical results for each analysis perfonned under SDW 21203 includes a minimum of one Laboratory Control Sample (LCS) and one method (reagent) blank and one duplicate sample analysis. Any exceptions have been noted in the "Comments" section.

QC and sample results are reported In the sanme units.

IV. Comments Alpha Specdroscopy Arnericium/Curium-isotooic by method RICH-RC-5080:

All results are below the CRDL and/or below the MDC. Except as noted, the LCS, sample duplicate, batch blank and sample results arc within contractual requirements.

Plutonium-238, 239/240 by methodRlCH-RC5010:

All results are below dte CRDL andfor below the MDC. The LCS, sample duplicate, batch blank and sample results ar within contraclual requirements.

Gas Proportlonal Counting Slrontlurn-90 by method R[CHl-RC-M0O6 The samples were processed twice. For the first process batch, the chemical yields were very low or zem. For the second processing set, the yields Were low but acceptable. However, the MDAs are greater than the CRDL. Through all the failed analyses and re-batching, a sample duplicate was inadvertently left out. Except as noted, the LCS, batch blank and sample results am within contractual Tequirements.

Gnmmn Spectroscopy Gamma Spec by method RICH-RC-5O17:

Seventeen oF the eighteen requested radionuclides have been reported for each sample. The Mi-212 was over eight half lives since collection, therefore, not reported. Except as noted, the LCS.

sample duplicate, batch blank and sample results arc within required limits.

WIVE Bechtel Corporation December 18, 2002 Page 3 Liquid ScIntlllatlon Counting Tsitlum by method R!CH-RC-5007:

The samples were dried and prepared for analysis before the technician realized these samples were supposed to have tritium analysis performed on non-dried samnple. No results will be reported for this test Technetlum-99 by method RICH-RC-5065:

The samples were dried and prepared for analysis before the technician realized these samples were supposed to have technlclum-99 analysis perfouned on non-dried sample. Any volatile technicium will not be captured by this test. All results arm below the CRDL and/or below the MDC The LCS, sample duplicate, batch blank, matrix spike, and sample results are within contratual requirements.

Carbon- 14 by method RICH{-RC-5022!

The samples were dried and prepared for analysis before the technician realized these samples were supposed to have carbon-14 analysis performed on non-dried sample. Any volatile carbon that would be driven off during the drying process will not be captured by this test. All results ae below the CRDL and below the UMC. The LWS, sample duplicate, batch blank and sample results are within contractual requirements.

Irmn-55 by method RICH-RC-5074:

All results are below the CRDL and below the MDC. The LCS is at 48%. Since all results are well below the CRDL, the data are accepted as is. Except as noted, the LWS, sample duplicate, batch blank, matrix spike, and sampic results are within contractual rcquirerents.

Nickel-63 by method RICHIRC-5069:

All results are below the CRDL and/or below the MDCQ The LCS, sample duplicate, batch blank, matrix spike, and sample results are within contractual requirements.

Plutonium-241 by method RICH-RC-5080:

The batch blank result is greater than the MDA but below the CRDL There appears to be some background counts, although most likely not Pu-241, In all the samples due to an extraneous source. The laboratory does not subtract the batch blank from sample results unless directed by the client, therefore, all samples may be slightly elevated in activity due to this source of beta energy. All results are below the CRDL andFor below the MDC. The LCS, sample duplicate, batch blank, matrix spike, and sample results are within contractual requirements STL RICEDLA 4

The components (xyz) arc evaturted to determine Their contribution to Ihe overall method unertainty.

The Individual component uncertainties tuj are then combinez using a statistical model that provides the most probable overall uncertainty value. AU conmonent uncertainties ar categorized as type A, evaluated by staitstical methods, or type B, evaluated by other means. Uncertainties not Included in the components, such s sample homogeneity, ae combined with the cowmonen auncertainty as the squar root of the sum-or-tim-squaras ofdhe Individual unertainties. The unc~itlty ussoclaied with the derived result Is the combined uncertainty (us) mrutiplicd by the coverage factor (12, or 3).

When the or mor sample replicates are used to derive the annlytica result, the type A uncertainty Is she standard deviation of the mean value (Slvy), where S Is the standrd deviation of thc derived mesults. The type B uncertalntles arm all other random or non-random components that are not Included In the standard deviation.

Uncertainty Estimation STn 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(x,y,z,...).

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

The individual component uncertainties (ui) 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 (us) 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.

Report Definitions Action Lev An agreed upon activity level used to trigger some action when the final result is greater than or equal to the Action Level. Often the Action Level is related to the Decision Limit.

Batch The QC preparation batch number that relates laboratory samples to QC samples that were prepared and analyzed together.

Bias Defined by the equation (Result/Expected)-l as defined by ANSI N13.30.

COC No Chain of Custody Number assigned by the Client or STL Richland.

Count Error (Ns) Poisson counting statistics of the gross sample count and background. The uncertainty is absolute and inthe same units as the result. For Liquid Scintillation Counting (LSC) the batch blank count is the background.

Total Uncert (Us) All known uncertainties associated with the preparation and analysis of the sample are propagated to give a measure

- Combined of the uncertainty associated with the result, u, the combined uncertainty. The uncertainty is absolute and in the Vneerflanty. same units as the result

(#s), Coverage The coverage factor defines the width of the confidence interval, 1, 2 or 3 standard deviations.

Factor CRDL (RL) Contractual Required Detection Limit as defined inthe Client's Statement Of Work or STL Richland "default" nominal detection limit. Often referred to the reporting level (RL)

Lc Decision Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume associated with the sample. The Type I error probability is approximately 5%. Lc=(I .645 Sqrt(24(BkgrndCnt/BkgrndCntMinySCntMin)) * (ConvFct/(EflYld*Abn*Vol) IngrFct). For LSC methods the batch blank is used as a measure of the background variability. Lc cannot be calculated when the background count is zero.

The number assigned by the LIMS software to track samples received on the same day for a given client. The i Lot-Sample No sample number is a sequential number assigned to each sample in the Lot.

I MDCJMDA Detection Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume with a Type I and 11 error probability of approximately 5%. MDC - (4.65

• I Sqrt((BkgmdCnt/BkgmdCntMin)/SCntMin) + 2.71/SCntMin) * (ConvFct/(Eff

• Yld

• Abn

• Vol)

• IngrFct). For LSC methods the batch blank is used as a measure of the background variability.

Primary Detector The instrument identifier associated with the analysis of the sample aliquot. I Ratio U-2341U-238 The U-234 result divided by the U-238 result The U-234/U-238 ratio for natural uranium in NIST SRM 4321C is 1.038. I Rst/MDC Ratio of the Result to the MDC. A value greater than I may indicate activity above background at a high level of confidence. Caution should be used when applying this factor and it should be used in concert with the qualifiers associated with the result.

RsVTottUcert Ratio of the Result to the Total Uncertainty. If the uncertainty has a coverage factor of 2 a value greater than I may indicate activity above background at approximately the 95% level of confidence assuming a two-sided confidence interval. Caution should be used when applying this factor and it should be used in concert with the qualifiers associated with the result.

Report DB No Sample Identifier used by the report system. The number is based upon the first five digits of the Work Order Number.

RER The equation Replicate Error Ratio = (S-D)/[sqrt(TPUs2 + TPUd2) as defined by ICPT BOA where S is the original sample result, D is the result of the duplicate, TPUs is the total uncertainty of the original sample and TP7Ud is the total uncertainty of the duplicate sample.

SWG Sample Delivery Group Number assigned by the Client or assigned by STL Richland upon sample receipt.

Sum Rpt Alpha The sum ofthe reported alpha spec results for tests derived from the same sample excluding duplicate result where Spec Rsts) the results arc in the same units.

, Work Order The LIMS software assign test specific identifier.

Yield The recovery of the tracer added to the sample such as Pu-242 used to trace a Pu-239/40 method.
