I. INTRODUCTION This report covers the Quality Assurance (QA) Program for the Analytical Services function of the Teledyne Brown Engineering Environmental Services (TBE-ES) laboratory for January through December 2017 .
A. Operational Quality Control Scope
: 1. lnterlaboratory The Teledyne Brown Engineering Environmental Services Laboratory Quality Control (QC) Program is designed to monitor the quality of analytical processing associated with environmental , effluent (1 OCFR Part 50) , and waste characterization (1 OCFR Part 61) samples .
Quality Control of radioanalyses involves the internal process control program , and independent third party programs administered by Analytics and Environmental Resource Associates (ERA) .
TBE-ES also participates in the Department of Energy's (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) administered by the U. S. Department of Energy. The MAPEP is a set of performance evaluation samples (e .g., water, soil , air filters , etc.) designed to evaluate the ability and quality of analytical facilities performing measurement on samples that contain hazardous and radioactive (mixed) analytes.
Quality Control for radioanalyses during this reporting period consisted of internal process check samples . Third-party process checks prepared by Analytics , ERA and the DOE's MAPEP are not reported during the first quarter of the year.
Inter-laboratory cross-check samples are received and reported as follows :
Analytics provides cross check samples quarterly in March , June, September, and November.
MAPEP provides samples semi-annually in February and September with required reporting dates in May and November, respectively, following sample receipt.
ERA provides samples semi-annually in April and October with required reporting dates in May and November, respectively, following sample receipt.
107
: 2. lntralaboratory The internal QC program is designed to include QC functions such as instrumentation checks (to insure proper instrument response) , blank samples (to which no analyte radioactivity has been added) , for contamination checks , and instrumentation backgrounds. Process controls (or process checks) are either actual samples submitted in duplicate (duplicates) in order to evaluate the precision of laboratory measurements , or blank samples which have been "spiked " with a known quantity of a radioisotope that is of interest to laboratory clients . QC samples are intended to evaluate the entire radiochemical and radiometric process. Process control and qualification analyses samples seek to mimic the media type of those samples submitted for analysis by the various laboratory clients. The magnitude of the process control program combines both internal and external sources targeted at 10% of the routine sample analysis load .
: 3. Quality Assurance Program To provide direction and consistency in administering the quality assurance program , TBE-ES has developed and follows a Quality Manual and a set of Standard Operating Procedures (SOP) . The plan describes the scheduled frequency and scope of Quality Assurance and Quality Control (QA/QC) considered necessary for an adequate QA/QC program conducted throughout the year.
Internal audits are performed on an annual schedule .
The laboratory may be audited by prospective customers during a pre-contract audit, and/or by existing clients who wish to conduct periodic audits in accordance with their contractual arrangements.
State audits are conducted to maintain state certification specific to client requirements and for the National Environmental Laboratory Accreditation Conference (NELAC) accreditation. The Nuclear Utilities Procurement Issues Committee (NUPIC) conducts audits of TBE-ES as a function of a utility's Radiological Environmental Monitoring Program (REMP) .
In 2017, an Internal Audit was started on November 13-14, but not completed until February 9, 2018 . The purpose of this audit was to verify compliance to requirements stated in Revision 30 of the TBE QA Manual , Sections 1 -16, and implementation of procedures. The results will be included in the 151 Qtr 2018 QA Report.
The following External Audits were hosted by TBE in 2017 :
* FEMA Lab Evaluation in support of Calvert Cliffs Ingestion Pathway Exercise (State of Delaware) on September 19
* BWX Technologies (BWXT) on November 6 - 9 2
108
* Toxco Materials Management Center (TMMC) Desktop Audit submitted November 30 The FEMA lab evaluation is part of a greater exercise to determine preparedness in case of a radiological emergency around the Calvert Cliffs Nuclear Power Plant. There were no outstanding issues and this audit is considered closed .
The purpose of the BWXT audit was to evaluate the TBE Quality Program and determine , on a sample basis , if the subcontractor is meeting the minimum requirements invoked by their documented quality program , and the requirements stated in active BWXT purchase orders . The audit identified one (1) nonconformity and no observations or suggestions . The finding has been addressed and the audit is considered closed .
The purpose of the Toxco audit was to maintain TBE on TMMC 's Approved Suppliers List (ASL) for radiochemical laboratory services .
No nonconformities were found and TBE remains on their ASL list for an additional three years . The audit is considered closed .
B. Performance Characteristics
: 1. lnterlaboratory Accuracy TBE-ES has adopted a QC acceptance protocol based upon two external performance models . For the interlaboratory programs that have established performance criteria (e.g ., established warning and failure limits) , the laboratory uses those established criteria to evaluate QC sample results . For the interlaboratory QC programs which have no pre-set acceptance criteria (e.g . Analytics Cross Check Program) , results are evaluated in accordance with TBE-ES internal acceptance criteria.
a)    Analytics' Evaluation Criteria Analytics' evaluation report provides a ratio of TBE's result and Analytics' known value . Since flag values are not assigned, TBE-ES evaluates the reported ratios based on internal QC requirements , which are based on the DOE MAPEP criteria .
b)    DOE Evaluation Criteria Handbook for the Department of Energy's Mixed Analyte Performance Evaluation Program (MAPEP) , Revision 13 (June 2012), pp 37-38 , retrieved from http://www.id .energy.gov/resl/mapep/handbookv13 .pdf 3
109

MAPEP 's evaluation report provides an acceptance range with associated flag values .
The MAPEP defines three levels of performance: Acceptable (flag= A) , Acceptable with Warning (flag = W) , and Not Acceptable (flag = N). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value. Performance is acceptable with warning when a mean result falls in the range from +/- 20% to +/- 30% of the reference value (i.e ., 20% < bias < 30%) . If the bias is greater than 30% , the results are deemed not acceptable.
False-positive/negative testing and sensitivity evaluations are used in radiological performance evaluations . The specific analytes used for testing vary among performance evaluation test sessions.
The MAPEP program uses false-positive testing to identify laboratory results that indicate the presence of a particular radionuclide in a MAPEP sample when , in fact , the actual activity of the radionuclide is far below the detection limit of the measurement. Not Acceptable (N) performance , and hence a false positive result , is indicated when the range encompassing the result, plus or minus the total uncertainty at three standard deviations , does not include zero (i .e. 2.5 +/- 0.2; range of 1.9-3.1). Statistically, the probability that a result can exceed the absolute value of its total uncertainty at three standard deviations by chance alone is less than 1%. The MAPEP uses a three standard deviation criterion for the false positive test to ensure confidence about issuing a false-positive performance evaluation .
A result that is greater than three times the total uncertainty of the measurement represents a statistically- positive detection with over 99% confidence .
Sensitivity evaluations are routinely performed to complement the false-positive tests . In a sensitivity evaluation , the radionuclide is present at or near the detection limit, and the difference between the reported result and the MAPEP reference value is compared to the propagated combined total uncertainties . The results are evaluated at three standard deviations . If the observed difference is greater than three times the combined total uncertainty, the sensitivity evaluation in "Not Acceptable". The probability that such a difference can occur by chance alone is less than 1%. If the participant did not report a statistically-positive result , a "Not Detected" is noted in the text field of the MAPEP performance report. A non-detect is potentially a false-negative result, dependent upon the laboratory's detection limit for the radionuclide.
4 110

False-negative tests are also performed in combination with the sensitivity evaluations. In this scenario , the sensitivity of the reported measurement indicates that the known specific activity of the targeted radionuclide in the performance evaluation sample should have been detected , but was not, and a "Not Acceptable" performance evaluation is issued . The uncertainty of the MAPEP reference value and of the reported result at three standard deviations is used for the false-negative test.
The false-positive/negative and sensitivity evaluation tests are conducted in a manner that assists the participants with their measurement uncertainty estimates and helps ensure they are not under estimating or over inflating their total uncertainties. If the total uncertainty is over-inflated in order to pass a false-positive test, it will result in a "Not Detected" if the test is actually a sensitivity evaluation . The opposite is true for a false-positive test. False-negatives and failed sensitivity evaluations can also result from under-estimating the total uncertainty. An accurate estimate of measurement uncertainty is required for consistent performance at the acceptable level.
c)   ERA Evaluation Criteria The ERA evaluation report provides an acceptance range for control and warning limits with associated flag values . ERA's acceptance limits are established per the US-EPA, NELAC, state-specific performance testing program requirements , or ERA's SOP for the Generation of Performance Acceptance Limits , as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.
d)   NRC Resolution The laboratory also participates in the NRC Resolution Criteria with some laboratory clients to primarily evaluate double-blind 10 CFR Part 50 performance. The NRC Resolution Criteria are based on an empirical relationship , which combines prior experience and the accuracy needs of the program. The data is restricted to the individual client and is not included in this report.
: 2. lntralaboratory Accuracy Acceptance Criteria a) Process Controls For a group of test measurements to a given spike level , the measure of accuracy is the percent recovery of the sp ike activity 5
111

found versus the added spike activity. The percent recovery is calculated as follows:
(Am I As) 100 Where : Am= the activity measured As = the spiked activity Internal Process Control results use TBE-ES acceptance criteria of 70%-130% recovery. Warning limits are set from 70%-80% and 120%-130%. Results evaluated as "Warning" are evaluated for trends of low bias or high bias and are used to detect potential problems. The laboratory's internal acceptance criteria are based on MAPEP's defined performance levels of bias greater than 30% .
A matrix spike (MS) sample is an aliquot of a sample spiked with a known concentration of a target analyte prior to sample preparation and analysis . The matrix spike is used to document the bias of a method in a sample matrix. Matrix spike results use acceptance criteria of 60%- 140% recovery.
b) Other Measures Backgrounds , which represent the ambient signal response recorded by measuring instruments , are independent of radioactivity contributed by the radionuclides being measured in the sample .
Blank samples are acceptable if they do not contain any three-sigma statistically positive activity of the target parameters, unless the associated samples are positive .            If all sample results associated with the blank are greater than the MDC , then the blank MDC shall be less than the activity of the least active sample in the work order. If possible , equivalent media for preparing laboratory processing blanks will be used .
Replicate (duplicate [DUP]) and matrix spike duplicates (MSD) samples are produced by taking two aliquots from the same process check sample and assigning each aliquot a different Lab Sample Number. In cases of replicate analyses where there are no "known " values , the analyses will be evaluated for precision only. The matrix spike duplicates are split samples spiked with identical concentrations of a target analyte used to evaluate precision and bias . They are carried through the complete sample preparation and analytical procedure . Precision is evaluated by calculating the Relative Percent Difference (RPO) between the two samples . Relative Percent Difference is calculated as the 6
112

absolute difference between two values normalized to the average value , expressed as a percentage:
                % RPO= (abs[orig - dup] / [orig + dup]/2) x 100 The matrix spike duplicate is calculated as the absolute value of the original activity minus the duplicate activity divided by the spike activity expressed as a percentage . If the original activity is not detected then the activity is considered zero (0).
        % MSD = (abs[orig activity - dup activity]/spike activity) x 100 (Recovery)
For purposes of analytical reporting , each analytical result specifies the radionuclide concentration and the a posteriori Minimum Detectable Concentration (MDC) . TBE-ES calculates the a posteriori MDC using the sample's actual measurement parameters (i.e. , sample volume , chemical recovery, instrument background , etc.) to demonstrate that the Nuclear Regulatory Commission 's (NRC 's) a priori MDC has been met for each radionuclide/sample. By TBE-ES policy, the a posteriori MDC must be less than the required NRC a priori MDC .
: 3. Investigations and Nonconformance Reports QC investigations are initiated when QC results fall outside of the QC criteria . Other investigations may arise from unanticipated situations which are not clearly defined in the procedures or bounded by pre-established performance criteria , but have the potential of becoming QA-related issue(s) .         The QA investigation is the mechanism to quickly ascertain if there is "due cause" to issue a formal NCR .
An NCR is issued when an investigation finds "due cause" to document formal investigation into the root cause of the failure , the corrective action taken , and the action taken to prevent recurrence.
Investigations may include review of procedures , interviews of personnel, review of laboratory and instrument logbooks ,
observation of analyst techniques and any other items identified as necessary to resolve the issue.
For intercomparison performance evaluation samples it is TBE 's policy to issue an NCR for unacceptable results.

II. ANALYTICAL SERVICES QUALITY CONTROL SYNOPSIS A. lnterlaboratory Cross-Check Program During this reporting period , 25 nuclides associated with six media types (Air Filter, Charcoal [Air Iodine], Milk, Soil , Vegetation and Water) were analyzed . Samples were obtained from Analytics , the Department of Energy's (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) and Environmental Resource Associates (ERA) . Media types representative of client analyses performed during this reporting period were selected . The results are presented in Attachment A .
: 1. Analytics Environmental Cross Check Program Fifteen nuclides in milk, air particulate , air iodine (charcoal) and water samples were evaluated for four sets of cross-checks during March -
December, 2017 . All of the environmental analyses performed were reported as within the acceptable/acceptable with warning criteria except for one Cr-51 in soil sample .
NCR 17-16 was initiated to address the in-house Cr-51 failure and a Corrective Action was issued . All raw data and associated QC data were reviewed and fell within acceptance limits .
: 2. DOE's MAPEP Quality Assessment Program Thirteen nuclides in water, air particulate , soil , and vegetation samples were evaluated in March - December, 2017 . All of the environmental analyses performed were reported as within the acceptable/acceptable with warning criteria except for one U-238 in air particulate sample.
NCR 17-15 was initiated to address the in-house U-238 failure and a Corrective Action was issued . All raw data and associated QC data were reviewed and fell within acceptance limits .
: 3. ERA Environmental Cross Check Program Twelve nuclides were evaluated in air particulate and water samples during March - December, 2017 . All analyses performed were within the acceptable criteria except for Zn-65 , Sr-89 and Sr-90 in water samples (one each) .
NCR 17-09 was initiated to address the in-house Zn-65 and Sr-89 failures . Corrective Actions for each nuclide were issued. All raw data and associated QC data were reviewed and fell within acceptance limits .
8 114

NCR 17-19 was initiated to address the in -house Sr-90 failure and a Corrective Action was issued . All raw data and associated QC data were reviewed and fell within acceptance limits B. lntralaboratory Cross-Check Program During this reporting period , 37 nuclides in various matrices, including air particulate , animal , charcoal , fish , soil/solid , and water, were analyzed by means of the laboratory's internal process control program . The compilation of intralaboratory comparison data for this reporting period is summarized in Attachment B. (Note: Only gamma nuclides that are typically seen in samples are included in the attachment - a complete list is available upon request) .
The TBE-ES laboratory's internal process control program evaluated 3898 analyses during this period .
: 1. Blanks During this reporting period , all 1660 environmental blanks analyzed were less than the MDC .
: 2. Spikes During this reporting period , all 1639 environmental spikes and matrix spikes analyzed were within the acceptance criteria .
: 3. Duplicates All of the 3788 duplicate sets analyzed were within acceptance criteria .
C. Non-Conformance Reports (NCRs)
Nine new NCRs were issued for this reporting period (total of 19 for 2017). See Attachment C for the non-conformance reports . Section II A gives detailed accounts of the non-conformances initiated for interlaboratory cross-check program failures .
D. Observation Reports No observation reports were issued for this reporting period .
E. Instrumentation TBE-ES uses the statistical principle method of evaluation for instrument quality control check data based on the mean , 2-sigma and 3-sigma set point model or uses pre-set tolerance limits. Each detector is checked prior to use for that day and the resulting data points are automatically compared to statistical baselines to determine the instrument's 9
115

acceptability for counting . Control charts showing this data are available during audits or upon request.
Gamma Spectroscopy:
Gamma detectors are routinely monitored for energy, full width at half maximum , efficiency, and background . TSE-ES gamma detectors operated without incident during this reporting period . Occasional second runs (as allowed by our QA program) were necessary to verify acceptable operation. Some amplifier fine gain adjustments and liquid nitrogen addition to the dewars were also necessary when data trends indicate an energy drift on the detector.
Liquid Scintillation Counters (LSC) :
LSC instruments, used in tritium , C-14 , Ni-63 and other low-energy beta-emitters , are monitored for background and efficiency. The reliability of these instruments is exceptional with zero instances of background or efficiency values outside of control limits.
Alpha/Beta Gas Flow Proportional (GFP) Counters :
GFP detectors , used for gross alpha/beta , Sr-89/90 , 1-131 (Low Level) ,
and other nuclides, are monitored for background and efficiency. TSE-ES GFP detectors operated without incident during this reporting period.
Occasionally, second runs (primarily for alpha due to the sensitivity of source placement) were necessary to verify acceptable operation or because of low P-10 pressure . After gas change-out and purging ,
control check values return to control norms .
Alpha Spectroscopy:
Alpha detectors are routinely monitored for energy, full width at half maximum , efficiency, and background. TSE-ES alpha detectors operated without incident during this reporting period. Occasional second runs (as allowed by our QA program) were necessary to verify acceptable operation .

N R 17-01             Supplemental Sheet Description of Nonconformance:
TBE-2008 Re 8 did not have a section on delayed counting for GR-A by EPA 900.0.
Cause:
Although TB E was aware or the 7- hour delayed counting for OR-A in drinking water. it was not properly documented in procedure TBE-2 008 .
Corrective Action to Pre ent R currence:
During the audit.. proced\.lre TB :-2008 was updated to state that samples may be cmu1ted for beta activity immediately after drying; but alpha counti ng should be delayed al least 72 hours until equi li brium has occurred .

==Subject:==
Gross Alpha and/or Gross Beta Activity in Various Matrices A1 .3.5    Cool, weigh, and count at the alpha and the beta activities.
NOTE:        Enter sample information and weights in the laboratory logbook and/or LIMS. Print the worksheet. See note (b) under procedure A 1.1.3 above.
NOTE:        Samples may be counted for beta activity immediately after drying; but alpha counting should be delayed at least 72 hours until equilibrium has occurred.
A1.3.6     If sample particles tend to be airborne, treat the sample with a few drops of Lucite solution, air-dry, and count A1.4       Calculation and Reporting A1.4.1     Alpha Activity Calculate alpha activity, in pCi/L, by the equation Alpha = net cpm x l,000 2.22ev Where:          &  = calibrated overall counter efficiency (A 1.6) v .=   volume of sample counted, in ml.
Express the counting error as described in A1 .4.3 below. Similarly, calculate and report the alpha activity in picocuries per kilogram of moist biologic material or per kilogram of moist and per kilogram of dry silt.
NOTE:        The DEP suggests reporting detection limits when no activity is found. The 4.66 sigma criterion is most common when assigning detection limits.
A1.4.2     Beta Activity Calculate and report the gros;; beta activity and counting error in picocuries per liter of water or fluid, per kilogram of moist (live weight) biologic material, or per kilogram of moist and per kilogram of dry silt, according to A 1.4.1 and A 1.4.3.
To calculate picocuries of beta activity per liter, determine the value of & in the above equation as described in A 1.6.

NCR 17-02             Supplemental Sheet Description ofNonconformance:
The client requested a rerun for H-3 for sample L70587-l. The rerun result did not confirm the original result.
Cause:
The sample had a larger quenching interference than the QC or other samples in the workgroup.
Corrective Action:
The sample was reran with a smaller aliquot minimizing the quenching interference.
All associated raw data and QA results were reviewed and found acceptable.
TBE feels this is an isolated incident considering this has never been observed before.

Client notified TBE that the K-40 result for sample 3 looked unusually low .
Cause:
It was determined that the weights for sampl number 2 and sample number 3 had been witched during sample prep (human error).
Correcti e Action to Prevent Recurrence:
We wi ll implement barcode scanning during tare and (inal weighing during sample prep to eliminate human error.
We will program our LIMS to gi ea notification t project management i f a sample with a s ii matrix has been dried and entered into LIMS with a weight of

NCR 17-8                Supplemental Sheet Description ofNonconformance:
In October and November of 2016, Terry Owens conducted an internal audit on TBE-Knoxville. Three findings occurred at this time.
: 1. No records could be found for technician training of TBE-2001, revision 13, TBE-2013 revision 5, TBE- 4006, revision 7 or TBE 5001, revision 5.
: 2. Client requires gamma sample preservation for various water tests. Receipt Inspector stated she has not done any sample preservation since she started working there in July 2016, however, water samples from the client have been rec'd that require pH check per contract since that time.
: 3. A.) Maintenance Log books have been scanned and now reside on the Knoxville server. The Alpha Spectrometer Detector 27 had a sign on it saying it was out of service. The Maintenance Log gave no explanation about it being out of service. B.) For Alpha-Beta only the G3 Maintenance Log was filled in (T4 and G2 Maintenance Logs were not found) .
Cause:
: 1. During the transition of QA management, several training records were not able to be located.
: 2. Due to an oversight in training, the instruction to check the pH level of certain samples for an individual client was not passed on to the new sample receiving technician.
: 3. Though the detector 27 being down is noted in the electronic logbook, there was no description as to why the detector was down.
No maintenance needed in over 3 years for T4 and G2. There are no records to record. There is a location for T4 and G2 records to be recorded when maintenance is performed.
Corrective Action to Prevent Recurrence:
: 1. All procedure-training files have been reviewed and the three files listed as missing have been retrained and signed by the technicians.
: 2. The sample-receiving technician has been retrained to procedure TBE-4003.
A program was put into place to alert the sample-receiving technician when a sample needs preservation. The client was notified and no additional action was needed.
224 330
: 3. The count-room technicians were in tructcd to be more detailed in the logging of maintenance d neon the count r om equipment. Retraining wa done on h v lo use the electronic maintenan e log .
Objectiv
: 2. A copy of the sample rccci ing training document for TBE-4003.
: 3. screen shot f th - program lo alert t chnician that a sampl need to be pre crv d.
: 4. A copy of TBE-400., sec ti n 9.2

Use pH paper to ven*t Y PH of <2
* Do not place pH paper directly in cltent container.   . tt       y Instead transfer a small amount of sample to check pH. A clean disposable pipe e ma be use~ to transfer sample to pH paper. The pH is noted on the customer paperwork.
9.2.2    If the pH does not conform to customer requirements , note on the Sample ~eceipt VerificationNariance Report form . The PM will contact the customer regarding the vari ance.
9.2.29.2.3 For clients that require sample preservation at receipt, preserve as stated in 9.2.4 .1.
9.2.39.2.4 State Reportable Drinking Water Samples 9.2.3.19.2.4.1       If the samples are received out of pH specifications (<2), the laboratory will acidify with nitric acid within five (5) days and then analyze after at least sixteen (16) hours have elapsed. The dates and times must be documented.
The holding time for Iodine analyses is eight (8) days. (Do not acidify samples for H-3 or Iodine analysis.) Th is will be documented in the Sample Receipt VerificationNariance Report form .
9.2.3.29.2.4.2      The acids used for preservation and analyses must be checked for purity and documented. In the laboratory, this is done through the analysis of a method blank sample using the same lot of acid used for the preservation . If the samples are preserved prior to receipt at the laboratory, a trip blank must accompany the samples.
9.2.3.39.2.4.3      If the samples are out of holding time or improperly preserved, the PM will contact the client and inform them that any sample analysis conducted cannot be used fo r compliance purposes. This will be documented in the Sample Receipt VerificationNariance Report form . Samples out of holding time or with other flags cannot be reported as compliance samples.

Result of semi-annual ERA cross-check amples for Zn-65 and           r-89  ere reported as "Not cceptable '.
ause:
Zn The kn wn value for Zn-65 was usually low for this stud_ . The detector chosen for reporting gamma isotopes had a 46% enor for Zn-65. Th sampl was run in duplicate on another higher efficiency detector hich had an e1Tor of 13.9% for Zn-65 . The Zn-65 acti ity found on this detector was 59.3 or 110.2% fthe known value (53.8) .
Sr A ft.er revi ew of tbe ass iated Q samples (Blank LC , Dup and Lhe chemical re       ry, no apparent caus for th failure can be determined. It is interesting to note that for this stud , the known value was 66 .2 a cept.able range 53.8-74.3 and the st11dy mean (from al l Jabs reporting) was 58.5.

Th ample was counted overnight for 14 hours, however, the r-51 was piked at a very lo level and had a counting error of 65%. Also, r-51 has a 27-day half-life, making low-le el quantification even more diffi ult.
orrective Action to Pr vent R currence:
Effective corrective action cannot be taken for tbi spe i fie sample for the following rea on :
a) The error doe not appear to be taken into consideration for these re ults (only the reported value). When the rr r is taken into account for Cr-5 1 the highest value vwuld be 105% of the reference val u , whi h is acceptable.
b) The known result is significantly lo er than TB ' st pica! MDC for r-51 in a soil matri and would not t pically be repo11ed to clients (unle s specified).
The fai lure is specific to this ample and has no impact up n actual lient samples. T BE will further evaluate thi       R based upon the results of the next s i I era -check ample for Cr-51 .

1-1 I and gamma calculations were reported incorrectly for the K- 15 site (L 74884-4) due to incorrect sample time in LIM Cause:
The original chain of custody coll ection information did not match the sample container. A variance was done at login on I 0/13/17 and the collector was contacted via email to verify the information. He sent an updated CofC on 10/ 16/17, which matched the sa mpl e label info, but this was not entered into the LIMS at that time by the new proj ect manager, who wa in training at the time.
Corrective Action to Prevent Recurrence:
The proje t manager is aware of the importance of following up immediately with any change jn information from co ll ectors/clients and will be more diligent.
All as o iated raw data and QA results were reviewed and fou nd ace ptable. The results were not affected since the collection time was only changed by 15 minutes. A revised r po11 was sent to the client.

57.5). Instrument daily checks and background w re reviewed and passed. Our internal QC howed a low bias for Sr-90 at 74.5%, which passes the TBE crit rion 70% - 130%). Our ERA r-90 is also lo w at 64.8% f the known value. All of the sample we received was consumed in the original analysis o a rerun was not possible.
Conectivc Action to Prevent Recw-rence:
A rerun analysis would have helped to d terrnine the validity of the original result. Preparation of futur cross-check sampl swi ll be modified such that suffici nt sample remains for reruns if neces ary. LIMS programming will be enhanced to includ an auto-generated L D when a workgroup includes cross-check samples (as opposed to having a ch ice between LCSD or DUP).

Action Report/Improvement Plan                                                           Calvert Cliffs Nuclear Power Plant 3.3.3 Private Jurisdictions 3.3.3.1 Teledyne-Brown Laboratories 3.3.3.1.1 Teledyne Brown Laboratories Criterion: 1e 1 In support of the CALVEXl 7 Plume and Ingestion Pathway exercise, the Teledyne Brown Engineering radiological laboratory successfully demonstrated that equipment, maps, displays, monitoring instruments, dosimetry, Potassium Iodide (KI), and other supplies were sufficient to support emergency operations. This demonstration was conducted as an out of sequence activity on September 19, 2017.
The Teledyne Brown Engineering laboratory is located in Knoxville, TN. The State of Delaware had a letter of agreement dated July 7, 2017 with Teledyne Brown Engineering to provide laboratory analysis services to support the Delaware Radiological Emergency Plan.
Available equipment was sufficient to support sample receipt, preparation for counting, analysis and archival activities. Specific equipment and supplies demonstrated under this criterion include potassium iodide, dosimetry, monitoring equipment, and other equipment, as follows:
Potassium Iodide: The Teledyne Brown Engineering laboratory was located in Knoxville, TN, approximately 200 miles southwest of the Calvert Cliffs Nuclear Power Plant. Potassium iodide was not issued, stored or required at this location.
Dosimetry: Each individual working at the Teledyne Brown Engineering laboratory who entered areas where radioactive materials were handled was issued a Permanent Record Dosimeter (PRD). Several PRDs were inspected and found to have the individual's name and were dated Jul 01, 2017 - Dec 31, 2017. The Radiation Safety Officer (RSO) said that PRDs are changed every six months. The RSO said that the laboratory's maximum annual reported dose to an individual was 22 millirem. They did not use Direct-Reading Dosimeters (DRD), and did not have them for normal laboratory operations. If he determined that they needed them for radiation exposure monitoring in support of Delaware, he would contact Ludlum Measurements located in Knoxville to obtain DRDs.
Monitoring Instruments: The laboratory had two sets of hand held radiation survey instruments. One set was in use, the other was available for backup. The "in use" set of instruments was inspected. They had a Ludlum Model 19 microRoentgen survey meter, a Ludlm Model 3 survey meter with Model 44-9 detector (pancake Geiger-muller) and 44-38 detector (side window Geiger-Muller), and a Ludlum Model 4 with a 44-90 detector (alpha scintillation). All three survey instruments were labeled with a sticker showing they were calibrated on January 31, 2017. A laboratory technician conducted operational and source checks at the beginning of the day, each work day. All operational checks had already been done before the evaluation, so the technician demonstrated how she would do the instrument source check. The technician used appropriate radioactive check sources to verify that each instrument operated within an acceptable "range of readings" contained on a reference table for use during source checks. The range of readings criteria was determined by the Radiation Safety Officer 65 267 373

He appropriately explained that he used a radioactive check source to obtain a reference reading, then he established a range ofreadings that was +/- 20% of the measured value.
Additional Equipment and Supplies: The laboratory had signs on doors that posted radiation areas and radioactive materials areas. Additional supplies were available to set up more stringent contamination controls for processing post-accident samples (signs, step off pads, floor coverings, waste containers).
They had four high efficiency particulate air hoods where they would open sample shipping containers and prepare samples for analysis. They had appropriate personal protective equipment (lab coats, Tyvek suits, gloves, protective eyewear).
Additionally, the laboratory had extensive radiological sample preparation and analysis equipment.
They had multiple drying ovens, 15 in service gamma spectroscopy detectors (Canberra and Ortec),
Ortec and Tennelec gross alpha/beta gas flow proportional counters, alpha spectroscopy and liquid scintillation counting systems. They had a variety of containers with appropriate geometries for analyzing field samples (one liter, four liter, 150 milliliter, 300 milliliter, and petri dishes). They also had multiple commercial refrigerators and freezers, a large warehouse sized storage room for sample archival, and containers/space to store radioactive waste.
All activities were based on the plans and procedures and completed as they would have been in an actual event, except where noted in the extent of play agreement.
3.3.3.1.2 Teledyne Brown Laboratories Criterion: 3al In support of the CALVEXl7 Plume and Ingestion Pathway exercise, the Teledyne Brown Engineering radiological laboratory successfully demonstrated the use of appropriate dosimetry, Potassium Iodide (Kl) and procedures, and management of radiological exposure to radiation workers. This demonstration was conducted as an out of sequence activity on September 19, 2017.
The Teledyne Brown Engineering radiological laboratory had 20 employees. Seventeen employees were considered occupationally exposed radiation workers and were issued a Permanent Record Dosimeter (PRD) to wear while they were in radiologically controlled areas of the laboratory. Each person ' s PRD had their name printed on it and was dated Jul 01 , 2017 - Dec 31 , 2017. All laboratory personnel wore dosimetry on the front of their body in the chest area. Permanent Record Dosimeters were exchanged and read every six months. The Radiation Safety Officer (RSO) kept radiation dose records for all occupationally exposed employees.
The RSO explained that the laboratory used an administrative radiation exposure limit of 600 millirem/year. He had worked as the laboratory RSO for 15+ years and explained that the highest ever annual dose to a worker was 22 millirem. He said that a worker could be extended above annual limit of 600 millirem. He was authorized to approve radiation dose up to 4000 mi ll irem (annually). The Teledyne Brown Engineering corporate RSO would have to approve any radiation dose above that (up 66 268 374

He also explained that the laboratory had a lower radiation dose limit for declared pregnant females consistent with the requirements of Regulatory Guide 8.13 , Instruction Regarding Prenatal Radiation Exposure.
The RSO explained that they did not have Direct-Reading Dosimeters (DRD) for use on a routine basis.
If they determined they might need them due to processing a large volume of highly radioactive samples, he would contact Ludlum Measurements in Knoxville, TN to obtain the required equipment.
Additionally, he could contact his counterpart at Oakridge National Laboratory and request loan of DRDs.
Several packages from various nuclear power plants were being processed during the demonstration.
All sample shipping containers were surveyed upon receipt. A sample receipt technician surveyed containers for both radiation levels and contamination. The lab had sample receipt and holding areas for both low level environmental samples and " in-plant" samples that measured higher radiation levels.
All sample containers were surveyed and compared to receipt criteria posted in the sample receiving area. The technical would contact the RSO for direction if any sample container measured above 0.5 milliRoentgen/hour (mR/hr). The laboratory could receive and process samples with contact radiation levels measuring up to I 00 mR/hr. They had a holding area for samples with higher contact radiation levels.
The RSO also explained the facility ' s routine survey program. Areas where radioactive material was handled were surveyed weekly (radiation levels and removable contamination); administrative and non-radioactive materials areas were surveyed monthly. Routine radiation surveys were provided for review and found to be through and appropriate to be used in managing dose radiation to workers and contamination within the faci lity.
The Teledyne Brown Engineering laboratory was located in Knoxville, TN, approximately 200 miles southwest of the Calvert Cliffs Nuclear Power Plant. Potassium iodide was not issued, stored or required at this location.
All activities were based on the plans and procedures and completed as they would have been in an actual event, except where noted in the extent of play agreement.
3.3.3.1.3 Teledyne Brown Laboratories Criterion: 4c 1 In support of the CALVEXl 7 Plume and Ingestion Pathway exercise, the Teledyne Brown Engineering radiological laboratory successfully demonstrated the capability of performing required radiological analyses to support protective action decisions. This demonstration was conducted as an out of sequence activity on September 19, 2017.

Action Report/Improvement Plan                                                            Calvert Cliffs Nuclear Power Plant The Teledyne Brown Engineering radiological laboratory was located in an industrial area outside of Knoxville, TN. It was a contract laboratory that received and processed both low level environmental samples and higher radiation level "in plant" samples from various nuclear power plants. The laboratory supported Radiological Environmental Monitoring Program (REMP) monitoring programs as well as doing isotopic analysis for radioactive waste shipments. The State of Delaware had a Memorandum of Understanding dated July 7, 2017 with Teledyne Brown Engineering to provide radiological laboratory analysis services to support the Delaware Radiological Emergency Plan. The laboratory's agreement with the State of Delaware included an estimated 24-hour turnaround time for sample results once samples were received by the laboratory.
Sample Receipt: The laboratory building had a delivery bay with a roll up door where samples were delivered from FedEx, UPS and private carriers. The entire laboratory facility was under negative air pressure to ensure that all air flowed into the building and there was no effluent out. The laboratory had an area to process low level environmental samples and another room to process higher level "in plant" samples. Both rooms connected to the receipt bay. It was noted by the Laboratory Operations Manager that they routinely received and processed higher activity samples. He also explained that approximately 80% of their business was from nuclear power plants and nuclear plant personnel did a good job in packaging to ensure the exterior of the sample containers were below their receipt contamination limit of 1000 disintegrations per minute/ 100 square centimeters (dpm/100 cm2).
During the evaluation, several deliveries were made to the facility and sample packages received by a laboratory receipt technician. The technician did both radiation and contamination surveys on each outer package. Survey acceptance criteria was posted above the survey meter work station. She was to contact the Radiation Safety Officer (RSO) if any package measured above 0.5 milliRoengen/hour (rnR/hr) or had removable contamination above 1000 dprn/100 cm2. The RSO said that anything above those levels would likely be opened and the interior sample containers surveyed in the " in plant" room.
The laboratory's contact radiation exposure rate limit on an individual sample was 100 mR/hr.
All samples received had appropriate chain of custody paperwork that included the requested analysis (e.g. gamma, tritium, Sr90, etc.). The Quality Assurance Manager and laboratory receipt technician provided a sample of a sample chain of custody for review. The Quality Assurance Manager said in most cases, they received an electronic copy for review prior to receipt of samples. A signed paper chain of custody form was included the package with the samples.
When samples were received, they were logged into the Laboratory Information Management System (LIMS). A bar coded label was printed and affixed to the sample. The sample location and processing status could be looked up in LIMS. It was also used to track whether an aliquot of a sample was taken; all parts were accounted for and ultimately resulted in displaying the final sample storage location (post processing).
During the demonstration, the receipt technician had multiple samples being received and processed.
They included milk, water, various fruits and vegetables, fish, soil and vegetation. It was noted that the samples the laboratory routinely handles were of the type to be received and analyzed in a nuclear 68 270 376

Unclassified Radiological Emergency Preparedness Program (REP)
Action Report/Improvement Plan                                                             Calvert Cliffs Nuclear Power Plant power plant post-accident response. Therefore, sample types and activity levels being shipped from Delaware for plume or ingestion phase analysis would not be atypical for this laboratory.
Sample Preparation: Once sample shipping containers were opened, chain of custody paperwork reviewed and entered into LIMS, the samples were removed from the shipping container and each sample inspected and surveyed. Laboratory technicians would typically wear a lab coat, gloves and protective eyewear. "In plant" samples, such as those for radioactive waste shipments, would be opened and processed in an adjacent room. The sample receipt and preparation areas had work areas with negative pressure hoods using High Efficiency Particulate Air (HEP A) filtration. The Radiation Safety Officer said they would set up a contamination control area in the "in plant" sampl e preparation room, complete with signs, step off pad and the requirement for addition al protective clothing. Contamination surveys would be performed to ensure contamination was not being spread. They would also store samples being processed in an area in the sample preparation room to prevent an increase in background radiation levels for the workers. It was noted by the evaluator that there was ample room to accomplish this task.
Based on the requested analysis, the sample container would be opened and the sample contents transferred to a container with the appropriate counting geometry. The Laboratory Operations Manager said that they used a variety of geometries for gamma analysis that would be appropriate for samples received from the State of Delaware. They had one and four- liter Marinelli containers, 150 and 300 milliliter bottles, small scintillation vials and petri dishes. Most of the leafy vegetation samples would be counted in the four-liter Marinelli. During sample preparation, the laboratory technician would break down the food product as specified in the agreement with the customer. For example, he might shuck corn or filet fish to ensure they analyzed only the eatable portion of the sample.
Samples requiring simple gamma analysis needed little preparation other than sometimes adding a chemical preservative, cutting up (e.g. corn stalks, meat), and putting into analysis containers.
Sometimes the client specified that the sample (such as soil) be dried prior to counting. Samples needing complex analysis, such as for Sr-90, would take longer to prepare. For example, a milk sample would have to be evaporated slowly to remove all of the water. At too high a temperature, the iodine would volatilize out of the milk. A milk sample for Sr-90 analysis could take up to two weeks. It was noted that the laboratory had extensive cold storage available for sample preservation. They had several refrigerators and freezers in the "in plant" preparation room, and another large room with multiple commercial refrigerators and freezers. The second room was primarily used to retain/archive samples after they were processed. The laboratory also had a program for disposal of radioactive waste and shipment to a waste processing facility. The laboratory would work out final radioactive waste disposal protocols with the State of Delaware.
Sample Counting: Once samples were prepared for counting they were transferred to the next room; the counting laboratory. This laboratory had extensive equipment such as gamma spectroscopy detectors, automatic gas flow proportional counters used to count particulate samples for gross alpha and beta, scinti ll ation counters that would be used for beta analysis such as Sr-89/90, alpha spectroscopy systems that would be used to analyze for transuranics . Laboratory counting equipment was within current calibration and had operational/source checks conducted dai ly/prior to use.

Action Report/Improvement Plan                                                            Calvert Cliffs Nuclear Power Plant The laboratory primarily analyzed samples for gamma isotopes. They had 15 operational high purity germanium (HPGe) detectors (Canberra and Ortec). All HPGe detectors were housed inside steel or lead lined caves to shield out background radiation. One HPGe detector was selected for review of calibration records, daily checks, system operation and sample analysis reports. The HPGe detector was calibrated to count samples in multiple geometries - as described in the sample preparation section above. Calibration sources were made by taking aliquots from two different Analytics mixed gamma sources. The Analytics gamma standards made by Eckert & Zeigler maintained traceability to the National Institute of Standards and Technology (NIST) as described in Regulatory Guide 4.15. The reference dates on the samples inspected were January I, 2014 and July I, 2011. Calibrations were done on the gamma spectroscopy equipment and compared with the documentation provided with the NIST gamma standard. Daily background and operational checks were done prior to equipment use. If the gamma spectroscopy system was out of specification, minor gain adjustments would be made by the Laboratory Operations Manager. As long as the spectroscopy equipment passed its performance tests, a full recalibration was not required on a specific frequency.
Samples were counted using a system comprised of the HPGe detector and Canberra counting and analysis software. It was noted by the Laboratory Operations Manager, that they had made modifications to the data entry portion of the software to make it more efficient. Canberra had reviewed and approved the modification.
Per laboratory analysis procedures, the laboratory would use a default I 00-minute count time unless otherwise specified by the customer. The I 00 second count time, and associated detection capability per isotope are documented in, "Gamma Emitting Radioisotope Analysis, TBE 2007, Revision 8." It is noted that the default count time and associated Minimum Detectable Activity (MDA) are to meet routine environmental monitoring criteria and are much lower than would be needed for accident analysis. Count times would be adjusted based on client input and the specified MDA by sample type and isotope. Likely Delaware post-accident sample count times could be adjusted to 10-15 minutes and meet the standards needed for calculation of projected doses from airborne radioactivity, ground deposition and ingestion of food products. Specifying a lower count time (and associated MDA) could significantly reduce the time for doing doses projections and making protective action recommendations to decision makers.
Unless specified otherwise, the laboratory would use their nuclear power plant isotopic library to compare sample counts against and generate a report of activity by sample type. The analysis library was reviewed and found to contain the key isotopes expected in a nuclear power plant accident.
Analysis Review: Once a sample was counted, a report was generated, and could be customized to the client's specification. The report would be reviewed and signed by both the radiochemi st and the Laboratory Operations Manager. The Laboratory Operations Manager reviewed a printout of a recent water sample and explained all of the parameters he reviewed prior to signing the document. Some of the items verified were that the count met the customers specification for MDA for critical isotopes and the calculated activity was in the client specified units . It was noted that if an isotope was not contained in the analysis library, and significant counts were collected in that channel, the software would include a listing of possible isotopes that could be included in a re-analysis of the spectrum.

Electronic files were backed up nightly to Teledyne Brown Engineering servers located in Huntsville, AL. Paper copies of analysis reports were maintained on file in the laboratory or transferred to an archival storage facility nearby. It was noted that some clients required the laboratory maintain records for 60+ years.
Sending results to Delaware: Once laboratory reports were reviewed and signed, the signed copy would be scanned into a Portable Document Format (PDF) file. The PDF and a Comma Separated Values (CSV) file would be sent to the client. The Laboratory Project Manager said that the CSV file, or an Excel file could be customized so the client received a spreadsheet with the isotopes of interest, the sample results in the units needed for dose calculations, and the associated MDAs. An example was provided for review. Having a customized electronic report formatted for the State of Delaware would significantly reduce the time required to do data ent1y for dose projections (the data from an Excel file could be copied/pasted into a calculation spreadsheet).
Training and Qualification: The Teledyne Brown Engineering laboratory had a training and qualification program for laboratory personnel. Personnel underwent extensive training and had a qualification document completed and signed for each task they were qualified to perform. A signed qualification record for the laboratory radiochemist was provided for review.
All activities were based on the plans and procedures and completed as they would have been in an actual event, except where noted in the extent of play agreement.
In summary, the status of DHS/FEMA criteria for the Private jurisdiction is as follows:

NONCONFORMITY Nonconformity Vl-01

== Description:==
Teledyne Brown Engineering could not provide evidence that the QA Manager is tracking preventive actions per the procedure.
Requirements : TBE-1012 Revision 6, paragraph 5.7.3, states that "Preventive actions tracking by the Quality Assurance Manager shall include the initiation of such actions and application of controls to ensure that they are effective."
Discussion: While reviewing documentation for*preventive actions it was noted that preventive actions tracking documentation could not be provided for review. A discussion with the current QA Manager revealed that due to recent personnel change of QA Managers that documentation is difficult to locate at this time.
Vendor's Response : The tracking form was located and updated. SEE ATTACHED Cause: Former QA Manager's last day on-site was Aug 15 and new QA Manager did not start until Nov 6. No instructions available for tt1is fo rm at the time of the audit.
Immediate Co'rrective Action : Form wa s located and updated.
Corrective Action to Prevent Recurrence : Curren tly in the process of updating QA Office procedures to include instructions for track ing, document locations, etc.
Describe the actions taken to determine whether a similar issue exits elsewhere: NA Describe why this issue does or does not affect product conformance to requirements : No effect on product conformance to requirements (paperwork and organization issue in the QA office). TBE considers this nonconformity closed.
