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

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 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 I

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 monitoring program. These include, but are not limited to, sample collection, I

preservation and shipment, receipt of samples by the laboratory, preparation and 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 I

Guide 4.15, "Quality Assurance for Radiological Monitoring Programs (Normal Operations) - EfHuent Streams and the Environment", which defines an acceptable QA program.

The guidance contained in Regulatory Guide 4.15 and NRC I

10CFR50, Appendix B, "Quality Assurance Criteria for Nuclear Power Plants and 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 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 I

PBRF Gamma Spectroscopy Systems and/or Liquid Scintillation Analyzer. For the 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 analytical results are then compared with the replicate analysis results for I

agreement.

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 Laboratory for gamma spectroscopy and tritium analysis approximately twice a year. Results are submitted via the Internet and evaluated for agreement.

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 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.

3.7 This report is divided into the following sections:

Section 4.0 - Laboratory Program Section 5.0 - Inter-laboratory and Intra-laboratory Comparison Analysis Section 6.0 - Quality Control Checks Section 7.0 - Background Determinations Section 8.0 - Blank Sample Analysis Section 9.0 - Cross-check Program Section 10.0 - Laboratory/Sample Deviation Reports Section 11.0 - Attachments Brief discussions and summaries as well as applicable acceptance criteria are included for each section. Analytical results, which did not meet the specified acceptance criteria, are noted and discussed.

4.0 LABORATORY PROGRAM 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 spectroscopy units, one liquid scintillation counter, and three gas flow proportional alphalbeta counters. The laboratory is operated by qualified personnel with 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 period.

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.

TABLES 1 &2 - NOTES To determine agreement:

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.
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 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.

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" column. The corresponding Sample Deviation Report (SDR) number can be located in the "SDR Number" column.

9.0 CROSS-CHECK PROGRAM 9.1 PBRF participates in the United States Department of Energy (DOE) Mixed 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 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 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 sample matrix. MAPEP Series results are shown in Attachment B.

9.2 Tritium cross-check samples obtained from Eckert & Ziegler Analytics were 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 were within the acceptable range of the standard for both series. Cross-check results are shown in Attachment B.

10.0 LABORATORY/SAMPLE DEVIATION REPORTS 10.1 A Laboratory/Sample Deviation Report (SDR) provides a method to document sampling or sample analysis conditions that are adverse to quality.

N/A 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.

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 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.

CORRECTIVE ACTIONS ANDIOR COMMENTS 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 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 be given a 43,200 second count time.
