SUMMARY

I 1 1.1

.1 Gamma Spectroscopy Systems I 1.1.1 During the report period of January 1, 2008 and December 31, 2008, PBRF Laboratory personnel performed 4190 gamma spectroscopy sample analyses of 3006 samples. PBRF performed a total of 1547 quality I assurance analyses. They include:

29 blank analyses on 29 samples I

615 Quality Control (QC) checks I

615 Background checks 15 Cross-check Program sample analyses on 3 samples I

24 inter-laboratory comparison (replicate) analyses on 12 samples

249 intra-laboratory comparison (replicate) analyses on 132 samples I 1.1.2 Of all the QA samples that were analyzed on the PBRF Gamma Spectroscopy Systems, there were 4 discrepancies that required I documentation of a Sample Deviation Report (SDR).

1.2 Liquid Scintillation Analyzer I 1.2.1 PBRF laboratory personnel performed 523 tritium sample analyses during this report period. PBRF performed a total of 1789 analyses of quality I assurance (QA) samples. They include:

612 analyses on 3 reference standards I

227 analyses on 227 blank samples I

454 analyses on 2 background samples

454 analyses on 2 QC Check samples I

8 Cross-check Program sample analyses on 2 samples I

20 inter-laboratory comparison (replicate) on 20 samples

14 intra-laboratory comparison (replicate) on 14 samples I 1.2.2 Of all the QA samples that were analyzed on the PBRF Liquid Scintillation Analyzer, there were no discrepancies that required documentation of a I Sample Deviation Report .

I~------------------------------~

I 1.3 Four Sample Deviation Reports were completed as a result of deficiencies found I during this report period. Two were associated with MAPEP Series 18 Co-60 failures. Two were failures to attain agreement between intra-laboratory replicate analyses of K-40. These failures were investigated by the Laboratory Manager and I corrective actions were documented. Refer to Section 10.0 of this report.

2.0 INrRODUCTION I 2.1 This report has been prepared by the PBRF Radiological Laboratory Manager in accordance with PBRF procedure RP-060, PBRF Radiological Laboratory Quality I Assurance/Quality Control Program. It provides a summary and interpretation of PBRF Laboratory QA Program for the period of January 1, 2008 to December 31, 2008.

I 3.0 DISCUSSION I 3.1 A QA program is an essential part of any radiological monitoring program. It provides reasonable assurance that the results of radiation measurements are valid. To be effective, elements of QA must be evident in all phases of the I monitoring program. These include, but are not limited to, sample collection, preservation and shipment, receipt of samples by the laboratory, preparation and analysis of samples and data review and reporting. An effective QA program will I allow for the identification of deficiencies in all monitoring processes so that appropriate investigative and corrective actions can be implemented.

I 3.2 The United States Nuclear Regulatory Commission (USNRC) published Regulatory Guide 4.15, "Quality Assurance for Radiological Monitoring Programs (Normal Operations) - EfHuent Streams and the Environment", which defines an acceptable I QA program. The guidance contained in Regulatory Guide 4.15 and NRC 10CFR50, Appendix B, "Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants" has been adopted by the PBRF Facility. Procedures I have been written and implemented to meet the objectives of these position documents.

I 3.3 Samples are typically analyzed only once because of workload constraints.

Therefore, laboratory personnel must be confident in the analytical results which are reported. One means of achieving confidence in the results is through the analysis I of QA samples. This report provides the analytical results of various QA samples processed by the PBRF laboratory during this period.

I 3.4 Quality Control checks are performed on at least 5% of all samples analyzed on the PBRF Gamma Spectroscopy Systems and/or Liquid Scintillation Analyzer. For the purpose of comparing results, these samples may be analyzed in duplicate by an I independent laboratory (inter-laboratory comparison) or by PBRF (intra-laboratory comparison) in their entirety or split to perform multiple analyses. The original analytical results are then compared with the replicate analysis results for I agreement.

I~------------------------------~

I 3.5 The PBRF laboratory participates in the United States Department of Energy Mixed Analyte Performance Evaluation Program (MAPEP) and the Eckert & Zeigler Analytics cross check programs. Blind spike samples are sent to the PBRF I Laboratory for gamma spectroscopy and tritium analysis approximately twice a year. Results are submitted via the Internet and evaluated for agreement.

I 3.6 Blank samples are analytical control samples, usually distilled water or verified clean (non-radiological) sand or soil, used to demonstrate that reported analytical results are not the result of Laboratory and/or Sample Processing Facility I contamination. They are used to evaluate the entire analytical procedure (sample preparation and analysis) and are prepared at the PBRF Facility for analysis in conjunction with batches or groups of regular samples.

I 3.7 This report is divided into the following sections:

I

Section 4.0 - Laboratory Program

Section 5.0 - Inter-laboratory and Intra-laboratory Comparison Analysis I

Section 6.0 - Quality Control Checks I

Section 7.0 - Background Determinations

Section 8.0 - Blank Sample Analysis I

Section 9.0 - Cross-check Program I

Section 10.0 - Laboratory/Sample Deviation Reports

Section 11.0 - Attachments I Brief discussions and summaries as well as applicable acceptance criteria are included for each section. Analytical results, which did not meet the specified I 4.0 acceptance criteria, are noted and discussed.

LABORATORY PROGRAM I 4.1 The PBRF Radiological Laboratory is designed to support the analytical requirements of decommissioning work activities, environmental program, and Final Status Survey. The laboratory consists of three high resolution gamma I spectroscopy units, one liquid scintillation counter, and three gas flow proportional alphalbeta counters. The laboratory is operated by qualified personnel with I documented training on all of the laboratory equipment. Sample processing is performed in accordance with site procedures and chain of custody is maintained for all samples. There were no significant laboratory program changes during this I period.

I~------------------------------~

I 5.0 INTER-LABORATORY & IN"rRA-LABORATORY COMPARISON ANALYSIS 5.1 For this report period, 24 gamma spectroscopy comparison analyses were I performed on 12 inter-laboratory samples and 249 gamma spectroscopy comparison analyses were performed on 132 intra-laboratory samples. This equates to approximately 6.5% of the total gamma spectroscopy sample analysis I performed during the report period. Two intra-laboratory comparison results were not in agreement and a Sample Deviation Report was completed for each. All of the remaining comparison analyses performed in this period were in agreement.

I 5.2 Air filter and smear samples are not typically sent to an off site laboratory for gross activity comparison analysis. In addition, the PBRF laboratory does not perform I gross activity analysis on water or soil samples. Therefore, no inter-laboratory or intra-laboratory gross alpha/beta comparative analyses were performed during this period.

I 5.3 For this report period, 14 intra-laboratory tritium comparative analyses were performed on 14 samples and 20 inter-laboratory tritium comparative analyses I were performed on 20 samples. This is approximately 6.5% of the total tritium sample analysis performed during the report period. All of the comparative analyses performed in this period were in agreement.

I TABLES 1&2 - NOTES To determine agreement:
I 1. The original result is divided by its associated one sigma uncertainty to obtain the resolution.
2. The original result is then divided by the corresponding replicate result to obtain the ratio.
I 3. The measurement is in agreement if the value of the ratio falls within the limits shown in Table 3 for the corresponding resolution. The criteria are similar to those listed in USNRC Inspection I Procedure 84750 "Radioactive Waste Treatment, and Effluent and Environmental Monitoring" with minor adjustments to account for activity concentrations with large uncertainties.
4. If both sample results are less than Minimum Detectable Activity (MDA), they are in agreement.
I When comparing a positive result to a <MDA result, the <MDA result is assumed to be positive activity and used to calculate the ratio.
5. Those sample analyses that do not agree are annotated by a "NO" answer in the "Agreement" I column. The corresponding Sample Deviation Report (SDR) number can be located in the "SDR Number" column.

7.0 BACKGROUND
DETERMINATIONS I 7.1 A background check is performed on the Gamma Spectroscopy Systems at least daily as required by procedure PBRF-RP-021, Rev. 2, Operation and Calibration of the ORTEC Gamma Spectroscopy System. Background determinations are I used to ensure that the counting environment is free of contamination.
Background results are plotted daily to observe trends and unusual results. A total of 615 background checks were performed on the PBRF Gamma Spectroscopy I Systems during this report period. All background checks were performed satisfactorily. No deficiencies were noted.
I 7.2 A background reference sample is analyzed daily prior to sample counting to calculate the figure of merit (FOIVI) quench indicating parameter (QIP) of E2/B.
This value is used to determine counting efficiency.
I 7.3 Two background samples are analyzed on the Liquid Scintillation Analyzer with each batch of samples. The background samples are prepared with de-ionized I water and scintillation cocktail. One background sample is placed before the sample set and one is placed after the sample set. Results are used to subtract a background count from the sample count and calculate an MDA. Background I samples were analyzed in 227 sample batches during this report period. No deficiencies were noted.
I 8.0 BLANK SAMPLE ANALYSIS 8.1 Sample Processing Facility and Laboratory Technicians prepare blank samples I during the processing of regular samples in accordance with RP-060. The analysis of blank samples ensures that measurement error is not the result of contamination of sampling equipment or processing techniques. The acceptance I criteria for blank sample results are no detectable PBRF related activity above the target Minimum Detectable Activity (MDA).
I 8.1.1 A total of 29 Gamma Spectroscopy Analyses were performed on 29 blank samples during this report period. No PBRF related gamma activity was detected in any blank sample above the analysis MDA.
I 8.1.2 A total of 227 tritium analyses were performed on 227 blank samples during this report period. No tritium activity was observed in any blank I sample above the analysis MDA.

I 9.0 CROSS-CHECK PROGRAM 9.1 PBRF participates in the United States Department of Energy (DOE) Mixed I Analyte Performance Evaluation Program (MAPEP). MAPEP Series 18 was issued in January 2008 and resulted in a Co-60 failure on the MaS (soil) sample and a Co-60 failure on the RdF (filter) sample. Co-60 was incorrectly identified in I the MaS sample, when in fact it was not present above the analysis sensitivity.
Co-60 was reported outside the acceptance range (> 30%) of the reference value and Cs-137 was> 20% for the RdF sample. A replicate analysis performed on I these results was in agreement with the reference values. The remaining results were within the acceptance range for each sample matrix. Series 19 was issued in August 2008. All reported results were within the acceptance range for each I sample matrix. MAPEP Series results are shown in Attachment B.
9.2 Tritium cross-check samples obtained from Eckert & Ziegler Analytics were I analyzed in January and July. Each sample was analyzed multiple times to reduce the counting uncertainty. The average of these analysis and uncertainties are then reported to Eckert & Ziegler Analytics. The cross-check sample results I were within the acceptable range of the standard for both series. Cross-check results are shown in Attachment B.
I 10.0 LABORATORY/SAMPLE DEVIATION REPORTS 10.1 A Laboratory/Sample Deviation Report (SDR) provides a method to document I sampling or sample analysis conditions that are adverse to quality. The identification of the condition adverse to quality, the cause of the condition, and the corrective action taken are documented and reported to the appropriate levels I of management.
10.2 Each SDR is completed in accordance with procedure RP-060, PBRF I Radiological Laboratory Quality Assurance/Quality Control Program.
10.3 A total of 4 SDRs were completed during this report period. Each incident was I investigated by the Laboratory Manager and corrective actions were addressed and all SDRs were closed. A copy of each SDR is provided in Attachment A. The SDRs consisted of the following:
I
SDR-08-001 - MAPEP MaS-18 Co-60 failure
SDR-08-002 - MAPEP RdF-18 Co-60 failure and Cs-137 waming I

I 2/4/08 111 :05 I N/A I ANALYTICAL PROBLEM MAPEP MaS-18 Soil sample results were in excess of the Co-GO reference value. The reported value was 14.3 Bq/kg and the reference value was 2.9 Bq/kg. As this was a sensitivity test for Co-GO, no acceptance range is given.
I I
I CORRECTIVE ACTIONS AND/OR COMMENTS A review of the gamma spectroscopy analysis for this sample revealed that the Co-50 1332 peak was not present I in the spectrum. Since the Gamma Vision library recognized the 1173 peak, it associated the region counts with Co-GO and reported an incorrect activity. This is not the library that is normally used to analyze PBRF soil samples,
but was used for MAPEP since the results are reported in Becquerels. The library was corrected to require both
peaks to be present to identify Co-GO in a sample.

I I
CORRECTIVE ACTIONS ANDIOR COMMENTS I The reported values are the numerical average for each nuclide of 5 trials. The standard deviation in the trial set is 0.6 8q for Co-60 and 0.7 8q for Cs-137. A replicate analysis was performed on these results. 80th the Co-60 and Cs-137 results were in agreement with the MAPEP reference values. The sample analYSis process for this I geometry was observed by the Laboratory Manager and no discrepancies were found. The samples were analyzed for 1000 seconds which is typical for this sample type. However, a significantly longer count time will improve the uncertainty and should result in a smaller variance between sample trials. Subsequent MAPEP filter samples will I be given a 43,200 second count time.
