2.0 INTRODUCTION

2.1 This report has been prepared by the PBRF Radiological Laboratory Manager in I accordance with PBRF procedure RP-060, PBRF Radiological Laboratory Quality Assurance/Quality Control Program. It provides a summary and interpretation of PBRF Laboratory QA Program for the period of January 1, 2009 to December 31, I 2009.

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 I valid. To be effective, elements of QA must be evident in all phases of the monitoring program. These include, but are not limited to, sample collection, preservation and shipment, receipt of samples by the laboratory, preparation and I analysis of samples and data review and reporting. An effective QA program will 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 I Operations) - Effluent Streams and the Environment", which defines an acceptable QA program. The guidance contained in Regulatory Guide 4.15 and NRC 10CFR50, Appendix B, "Quality Assurance Criteria for Nuclear Power Plants and I Fuel Reprocessing Plants" has been adopted by the PBRF Facility. Procedures 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 I reported. One means of achieving con'fidence in the results is through the analysis 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 I purpose of comparing results, these samples may be analyzed in duplicate by an independent laboratory (inter-laboratory comparison) or by PBRF (intra-laboratory comparison) in their entirety or split to perform multiple analyses. The original I analytical results are then compared with the replicate analysis results for agreement.

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

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 - Intra-laboratory and Inter-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 acceptance criteria, are noted and discussed.

4.0 LABORATORY PROGRAM I 4.1 The PBRF Radiological Laboratory is designed to support the analytical requirements of decommissioning work activities, environmental program, and I Final Status Survey. The laboratory consists of three high resolution gamma 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.

5.0 INTRA-LABORATORY & INTER-LABORATORY COMPARISON ANALYSIS I 5.1 For this report period, 489 gamma spectroscopy comparison analyses were performed on 284 intra-laboratory samples and 26 gamma spectroscopy I comparison analyses were performed on 21 inter-laboratory samples. This equates to approximately 8% of the total gamma spectroscopy sample analysis performed during the report period. Six intra-laboratory comparison results were I 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 For this report period, 22 intra-laboratory tritium comparative analyses were performed on 22 samples. This is approximately 7.3% of the total tritium sample analysis performed during the report period. All of the comparative analyses I performed in this period were in agreement.

5.3 To determine agreement, the original result is divided by its associated one sigma I uncertainty to obtain the resolution and the original result is then divided by the corresponding replicate result to obtain the ratio.

I 5.4 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 Procedure 84750, "Radioactive Waste Treatment, and I Effluent and Environmental Monitoring" with minor adjustments to account for activity concentrations with large uncertainties.

I 5.5 If both sample results are less than Minimum Detectable Activity (MDA), they are in agreement. When comparing a positive result to a <MDA result, the MDA value is assumed to be positive activity and used to calculate the ratio.

I 5.6 Those sample analyses that do not agree are annotated by a "NO" answer in the "Agreement" column. The corresponding Sample Deviation Report (SDR) number I can be located in the "SDR Number" column.

I I 6.0 QUALITY CONTROL CHECKS 6.1 A Quality Control Check is performed on the PBRF Gamma Spectroscopy I Systems daily before analyzing samples and immediately after changes in electronic components that may affect system operability. The results are compared to parameters specified in RP-021, Rev. 1, Operation and Calibration of I the ORTEC Gamma Spectroscopy System. If results are not within the prescribed ranges additional Quality Control Checks are performed to determine if cause is due to statistical variation or if system adjustments are necessary. Additional I checks are performed and verified prior to placing the system in operation. A total of 1146 Quality Control Checks were performed during this period. No Quality Control Check defiCiency resulted in removing a detector from operation.

I 6.2 A system normalization and calibration using flame-sealed unquenched Carbon-Carbon 14, Tritium, and background reference standards traceable to the National Institute I of Standards (NIST) is performed on the PBRF Liquid Scintillation Analyzer daily before analyzing samples and immediately after changes in electronic components that may affect system operability. The results are compared to parameters I specified in RP-020, Rev. 0, Packard TriCarb 2900 TR Liquid Scintillation Analyzer. Results that are not within the prescribed ranges are investigated prior to placing the system in operation. A total of 154 system normalization and I calibrations were performed. No deficiencies were noted.

6.3 Two tritium QC Check samples are analyzed on the Liquid Scintillation Analyzer I with each batch of samples. The QC check samples are prepared from a NIST traceable tritium source solution and scintillation cocktail. One QC Check is placed before the sample set and one is placed after the sample set. Tritium QC check I samples were analyzed in 105 sample batches during this report period. The results are compared to parameters specified in RP-020, Rev. 0, Packard TriCarb 2900 TR Liquid Scintillation Analyzer. Results that are not within the prescribed I ranges are flagged on the sample analysis report. No deficiencies were noted.

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 I the ORTEC Gamma Spectroscopy System. Background determinations are 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 534 I background checks were performed on the PBRF Gamma Spectroscopy 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 (FOM) quench indicating parameter (QIP) of E2/B. This I value is used to determine counting efficiency.

7.3 Two background samples are analyzed on the Liquid Scintillation Analyzer with I each batch of samples. The background samples are prepared with de-ionized 5

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 samples were analyzed in 105 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 and RP-020.

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 202 Gamma Spectroscopy Analyses were performed on 202 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 105 tritium analyses were performed on 105 blank samples during this report period. No tritium activity was observed in any blank sample I above the analysis MDA.

9.0 CROSS-CHECK PROGRAM I 9.1 PBRF participates in the United States Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP). Various sample matrices are I prepared for DOE by the Radiological and Environmental Sciences Laboratory (RESL) and sent to program participants for analysis. Participating laboratories report and receive results via the MAPEP website. PBRF receives a water, soil, I and air filter sample. MAPEP Series 20 was issued in January 2009. All reported results were within the acceptance range (+/- 30%) for each sample matrix. Series 21 was issued in July 2009 and resulted in a Co-60 failure on the air filter (RdF)

I sample. Co-60 was reported outside the acceptance range (> 30%) of the reference value for the RdF sample. A replicate analysis performed on these results was in agreement with the reference values. The reported results for this I geometry have consistently been biased high compared to the reference value.

This has been a recurring problem with this geometry and was reported to ORTEC service personnel. Investigation and additional testing is in progress to resolve this I issue. The remaining results were within the acceptance range for each sample matrix. MAPEP Series 20 and 21 results are shown in Attachment 4.

I 9.2 Tritium cross-check samples obtained from Eckert & Ziegler Analytics were analyzed in March and September. Each sample was analyzed multiple times to reduce the counting uncertainty. The average of these analysis and uncertainties I are then reported to Eckert & Ziegler Analytics. The cross-check sample results were within the acceptable range of the standard for both series. Cross-check results are shown in Attachment 4.

I Calibration of puck geometry on Detector #3 was checked and found to be 70% higher than the certificate value. The detector was calibrated on 121BIOB with a new standard. The calibration of the remaining geometries for Detector #3 were checked and found to be satisfactory <<10% of certificate value). The variance between the three detectors on I the daily QC Check (47mm Air Filter) is <1%. This detector was recalibrated for this geometry. ORTEC technical personnel have been consulted to determine the cause of this shift. All puck samples counted on Detector #3 since recalibration have been reanalyzed. All calibrations were checked on Detectors 1&2 and found to be satisfactory. A review of the calibration certificate files was conducted and found that the previous (old) calibration file had incorrectly I been selected in the SDF. The correct file was assigned and the old file was removed from the SDF. The laboratory technician was counseled to ensure the correct calibration files are used for analysis. No further action is required.

The acceptable bias is 30%. The reported value for C0-60 was 1.34 +/-0.08 Bq and the Acceptance Range was 0.72-1.34 Bq.

I I CORRECTIVE ACTIONS AND/OR COMMENTS The sample was analyzed twice on each of the 3 detectors for 43,200 seconds and the results averaged. A review was conducted of the reported results to ensure they were reported correctly. No discrepancies were found. A I replicate analysis was performed and the reported value and reference value were in agreement. The spectra for each trial were reviewed for peak shape and uncertainty and no anomalies were found. The sample was re-analyzed on Detector 1 after annual recalibration and the results (1.33 Bq.) were consistent with the reported value. The I reported results for this geometry have consistently been biased high compared to the reference value. This has been a recurring problem with this geometry and was reported to ORTEK. Investigation and additional testing is in progress to resolve this issue.
