[External_Sender] Hematite NRC / ORAU Split Sample Data

Mike, Thanks for sending the referenced documents (laboratory reports).

Admittedly I was a bit confused at your request for the conditions under which information was to be withheld. That is recognizing the fact that Westinghouse did not provide the laboratory reports to the NRC Region III requesting they be withheld from public disclosure in accordance with 10 CFR 2.390. Nor did Westinghouse provide an affidavit requesting information be withheld. Westinghouse is not requesting that any information within the laboratory reports be withheld.

After looking at the laboratory reports you sent us we assume you are referring to the statement on page 3 of each report that states This laboratory report is confidential and is intended for the sole use of TestAmerica and its clients. This is a standard clause inserted in all laboratory reports.

In performing FSS activities Westinghouse, as the owner of the information, Westinghouse has chosen to use the information by providing it to the NRC without any request to withhold the information. As such, Westinghouse provides its consent for release of the information to the NRC for public viewing by freely handing over the laboratory report to the NRC without a request to withhold.

1

To ensure this does not create an unnecessary issue which would delay termination of the license, Westinghouse is providing its position on the statement in the laboratory reports.

Westinghouse has submitted hundreds of these laboratory reports to NRC Headquarters as NonProprietary Class 3 in FSSFR document review submittals. Westinghouse does not consider the statement in the laboratory report to be a direct request to the NRC to withhold any information as the FSSFR documents do not request withholding in accordance with 10 CFR 2.390. Westinghouse considers this to be appropriate as all of the laboratory reports previously submitted to the NRC are reviewed by NRC Document Control and then placed on the docket which allows for public viewing. NRC Document Control has not requested that the statement be removed. Thus indicating to Westinghouse the acceptability of the laboratory reports and indicating it does not conflict with NRC document requirements.

In contrast, Westinghouse has from time to time provided a document in which the proprietary marking inadvertently had not been removed. This results in suspending processing of the document. Typically Jim Smith contacts me in that regard, the proprietary marking is removed, forwarded to NRC Document Control and the document continues to be processed. As NRC Document Control has consistently accepted the laboratory reports without out removal of the statement Westinghouse does not intend to remove the statement form any or all of the laboratory reports.

Additionally, Westinghouse is sensitive to not manipulating, editing, changing or revising any laboratory report. Westinghouse believes it is vital that documents submitted to the NRC are accurate and factual. It is also for that reason the statement in the laboratory report have not been manipulate, edited or whited out.

I have checked with Val Kelmeckis, next week is schedule is currently open Monday and Tuesday. It is also open Wednesday morning until 11 am Eastern. Please schedule in those time frames if possible.

RE: Hematite - NRC / ORAU Split Sample Data

Ken, NRC is in the final stages of our review and is ready to close the inspection associated with the core bore sampling performed in LSA 10-05 and 10-14. However, the documents you sent to us has statements to its confidentiality. Is the licensee requesting withholding of your sample analysis under 10 CFR 2.390? If so, NRC is requesting the conditions under which the information is required to be withheld. If not, please redact the confidentiality sentence in the PDF files.

NRC would also like to have an exit meeting next week concerning the results of the inspection (IR070-00036/2017002). When would the licensee be available for that telephonic exit meeting?

VOLATILE ORGANIC COMPOUNDS BY GC/MS Samples 4356-SS-171016-00-02 (160-25051-2) and 4356-SS-171016-00-04 (160-25051-4) were analyzed for Volatile Organic Compounds by GC/MS in accordance with EPA SW-846 Method 8260C. The samples were prepared on 10/26/2017 and analyzed on 10/26/2017, 10/30/2017 and 10/31/2017.

Sample TB-101617 (160-25051-5) was analyzed for Volatile Organic Compounds (GC/MS) in accordance with EPA SW-846 Method 8260C. The samples were analyzed on 10/22/2017.

The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) associated with batch 160-334197: Acetone, n-Butanol, and 2-Butanone (MEK).

Case Narrative 1 Client: Westinghouse Electric Company LLC TestAmerica Job ID: 160-25051-1 Project/Site: HDP RFP-CBA-022 (21 DAY TAT) 2 Job ID: 160-25051-1 (Continued) 3 Laboratory: TestAmerica St. Louis (Continued) 4 reported: (CCVIS 160-334197/2).

The continuing calibration verification (CCV) associated with batch 160-334197 recovered above the upper control limit for 5

Chloromethane. The samples associated with this CCV were non-detects for the affected analyte; therefore, the data was reported:

(CCVIS 160-334197/2). 6 Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 7 160-334208 and analytical batch 160-334197. An LCS/LCSD was performed to demonstrate accuracy and precision: (MB 160-334208/1-A). 8 Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 160-334128 and analytical batch 160-334995. LCS/LCSD performed to demonstrate accuracy and precision: (MB 160-334128/3-A).

9 The following sample was analyzed in preparation batch 160-334128 and analytical batch 160-334995 at reduced volume due to high 10 concentrations of target analytes: 4356-SS-171016-00-02 (160-25051-2). The reporting limits have been elevated by the appropriate factor. 11 The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) 12 associated with batch 160-334995: Acetone, n-Butanol, and 2-Butanone (MEK). A low-level LOQV was analyzed at the reporting limit (5ug/L) and the affected analytes were detected. Target analytes recovering above the reporting limit will be qualified and reported:

(CCVIS 160-334995/2). 13 The continuing calibration verification (CCV) associated with batch 160-334995 recovered outside acceptance criteria, low biased, for Chloromethane. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data was reported: (CCVIS 160-334995/2).

The continuing calibration verification (CCV) associated with batch 160-334995 recovered outside acceptance criteria, low biased, for Vinyl chloride. A reporting limit (RL) standard was analyzed, and the target analyte was detected. All but one of the associated samples were non-detect for this analyte; therefore, the data have been reported. The sample with Vinyl chloride detected will be re-analyzed for Vinyl chloride only: (CCVIS 160-334995/2).

The continuing calibration verification (CCV) associated with batch analytical batch 160-333061 recovered outside acceptance criteria, low biased, for 2-Hexanone and n-Butanone. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data was reported: (CCVIS 160-333061/2).

The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) associated with batch analytical batch 160-333061: 2-Butanone, 4-Methyl-2-pentanone, and Acetone. A low level CCV was analyzed at the base reporting limit of 1ug/L and the affected analytes were detected. Results for affected target analytes recovering above the reporting limit in the associated samples were qualified and reported: (CCVIS 160-333061/2).

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

4356-SS-171016-00-04 (160-25051-4) were analyzed for percent solids in accordance with EPA Method 160.3 MOD. The samples were analyzed on 10/18/2017. 6 No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. 7 RADIUM-226 BY GAMMA SPEC (21 DAY INGROWTH) 8 Samples 4356-SS-171016-00-01 (160-25051-1), 4356-SS-171016-00-02 (160-25051-2), 4356-SS-171016-00-03 (160-25051-3) and 4356-SS-171016-00-04 (160-25051-4) were analyzed for Radium-226 by gamma spec (21 day ingrowth) in accordance with EPA GA_01_R. The samples were leached on 10/17/2017, prepared on 10/18/2017 and analyzed on 11/09/2017.

9 Batch 332580: 10 Insufficient sample was provided for the following samples to fit the geometry: .500 mL Marn requested, only enough sample to fill 100 mL d = 1 geometry: 4356-SS-171016-00-02 (160-25051-2). 11 Insufficient sample was provided for the following samples to fit the geometry: Sample contained oily clay; clumping created gaps and 12 headspace: 4356-SS-171016-00-04 (160-25051-4).

Insufficient sample was provided for the following sample to fill a tuna can geometry calibrated for radium-226 analysis by gamma 13 spectroscopy: 4356-SS-171016-00-02 (160-25051-2). The use of a 100ml geometry could potentially bias the results low due to the loss of radon into the headspace of the container.

The sample exhibited a negative result for Ra-226 and Bi-214 greater in magnitude than the 3 sigma TPU. This occurrence was evaluated and determined to be random in nature. Sporadic occurrences such as this are statistically expected. No further action is required: (MB 160-332580/1-A).

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

4358-SS-171017-00-08 (160-25094-8), 4358-SS-171017-00-10 (160-25094-10), 4358-SS-171017-00-12 (160-25094-12) and 4358-SS-171017-00-14 (160-25094-14) were analyzed for Volatile Organic Compounds by GC/MS in accordance with EPA SW-846 Method 8260C. The samples were prepared on 10/26/2017 and analyzed on 10/26/2017, 10/30/2017, 10/31/2017 and 11/09/2017.

Sample TB-101717 (160-25094-15) was analyzed for Volatile Organic Compounds (GC/MS) in accordance with EPA SW-846 Method 8260C. The samples were analyzed on 10/21/2017.

The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) associated with batch 160-334197: Acetone, n-Butanol, and 2-Butanone (MEK). A low-level LOQV was analyzed at the reporting limit TestAmerica St. Louis Page 3 of 52

Target analytes recovering above the reporting limit were qualified and reported: (CCVIS 160-334197/2).

5 The continuing calibration verification (CCV) associated with batch 160-334197 recovered above the upper control limit for Chloromethane. The samples associated with this CCV were non-detects for the affected analyte; therefore, the data was reported: 6 (CCVIS 160-334197/2).

7 Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 160-334208 and analytical batch 160-334197. An LCS/LCSD was performed to demonstrate accuracy and precision: (MB 8 160-334208/1-A).

The sample analysis preceding sample, 4358-SS-171017-00-08 (160-25094-8), in preparation batch 160-334208 and analytical batch 9

160-334197, detected a target analyte (cis-1,2-Dichloroethene) above the upper calibration limit (200ppb). Sample 4358-SS-171017-00-08 (160-25094-8) was re-analyzed in a subsequent sequence to check for possible carryover. The target analyte was 10 detected in both analyses at comparable levels (13.6ppb/15.7ppb). The results of the original analysis are reported.

11 Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 160-334128 and analytical batch 160-334995. LCS/LCSD performed to demonstrate accuracy and precision: (MB 160-334128/3-A). 12 The following sample was analyzed in preparation batch 160-334128 and analytical batch 160-334995 at reduced volume due to high concentrations of target analytes: 4358-SS-171017-00-10 (160-25094-10). The reporting limits were elevated by the appropriate factor. 13 The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) associated with batch 160-334995: Acetone, n-Butanol, and 2-Butanone (MEK). A low-level LOQV was analyzed at the reporting limit (5ug/L) and the affected analytes were detected. Target analytes recovering above the reporting limit will be qualified and reported:

(CCVIS 160-334995/2).

The continuing calibration verification (CCV) associated with batch 160-334995 recovered outside acceptance criteria, low biased, for Chloromethane. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data was reported: (CCVIS 160-334995/2).

The continuing calibration verification (CCV) associated with batch 160-334995 recovered outside acceptance criteria, low biased, for Vinyl chloride. A reporting limit (RL) standard was analyzed, and the target analyte was detected. All but one of the associated samples were non-detect for this analyte; therefore, the data was reported. The sample with Vinyl chloride detected will be re-analyzed for Vinyl chloride only: (CCVIS 160-334995/2) .

Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 160-334128 and analytical batch 160-336544: 4358-SS-171017-00-14 (160-25094-14).

The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) associated with batch analytical batch 160-333039: Acetone, 2-Hexanone, n-Butanol, 4-Methyl-2-pentanone, and 2-Butanone. A low level CCV was analyzed at the base reporting limit of 1ug/L and the affected analytes were detected. Target analytes recovering above the reporting limit were qualified and reported: (CCVIS 160-333039/4).

The continuing calibration verification (CCV) associated with batch 160-333039 recovered outside acceptance criteria, low biased, for Bromomethane, 2-Hexanone, and n-Butanol. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data was reported.

The laboratory control sample (LCS) for analytical batch 160-333039 recovered outside control limits for the following analytes:

Bromomethane. A low-level LCS (LLCS), spiked at the reporting limit (RL), was prepared with this batch. The affected target analytes recovered within acceptance limits; therefore, the LLCS demonstrates the analytical system had sufficient sensitivity to detect the compounds had they been present. Since the affected target compounds were not detected in the samples, the data was reported and qualified: (LCS 160-333039/5) and (LCSD 160-333039/6).

10 With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control 11 limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, 12 the reporting limits are adjusted relative to the dilution required.

13 TestAmerica St. Louis attests to the validity of the laboratory data generated by TestAmerica facilities reported herein. All analyses performed by TestAmerica facilities were done using established laboratory SOPs that incorporate QA/QC procedures described in the application methods. TestAmericas operations groups have reviewed the data for compliance with the laboratory QA/QC plan, and data have been found to be compliant with laboratory protocols unless otherwise noted below.

The test results in this report meet all NELAP requirements for parameters for which accreditation is required or available. Any exceptions to NELAP requirements are noted in this report.

A low-level LOQV was analyzed at the reporting limit (5ug/L) and the affected analytes were detected. Target analytes recovering above the reporting limit were qualified and reported: (CCVIS 160-334197/2).

5 The continuing calibration verification (CCV) associated with batch 160-334197 recovered above the upper control limit for 6 Chloromethane. The samples associated with this CCV were non-detects for the affected analyte; therefore, the data were reported:

(CCVIS 160-334197/2). 7 Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 8 160-334208 and analytical batch 160-334197. An LCS/LCSD was performed to demonstrate accuracy and precision: (MB 160-334208/1-A).

9 The analysis preceding sample 4360-SS-171018-00-06 (160-25126-6), in preparation batch 160-334208 and analytical batch 160-334197, detected Tetrachloroethene above the upper calibration limit (200ppb). Sample 4360-SS-171018-00-06 (160-25126-6) was 10 re-analyzed in a subsequent sequence to check for possible carryover. The target analyte was detected in both analyses at comparable levels (24.7ppb/17.5ppb). The results of the original analysis were reported. 11 Due to sample matrix effect on the internal standard (ISTD) in preparation batch 160-334208 and analytical batch 160-334197, a dilution 12 was required for the following sample: 4360-SS-171018-00-04 (160-25126-4).

Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 13 160-334128 and 160-334129 and analytical batch 160-334995. An LCS/LCSD was prepared to demonstrate accuracy and precision: (MB 160-334128/3-A) and (MB 160-334129/3-A).

The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) associated with batch 160-334995: Acetone, n-Butanol, and 2-Butanone (MEK). A low-level LOQV was analyzed at the reporting limit (5ug/L) and the affected analytes were detected. Target analytes recovering above the reporting limit were qualified and reported: (CCVIS 160-334995/2).

The continuing calibration verification (CCV) associated with batch 160-334995 recovered outside acceptance criteria, low biased, for Chloromethane. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data was reported: (CCVIS 160-334995/2).

The continuing calibration verification (CCV) associated with batch 160-334995 recovered outside acceptance criteria, low biased, for Vinyl chloride. A reporting limit (RL) standard was analyzed, and the target analyte was detected. All but one of the associated samples were non-detect for this analyte; therefore, the data was reported. The sample with Vinyl chloride detected was re-analyzed for Vinyl chloride only: (CCVIS 160-334995/2).

Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 160-334129 and analytical batch 160-335165. An LCS/LCSD was analyzed in a previous batch to demonstrate accuracy and precision is associated with this sample: 4360-SS-171018-00-16 (160-25126-16).

The following sample was analyzed in preparation batch 160-334129 and analytical batch 160-335165 at reduced volume due to high concentrations of target analytes: 4360-SS-171018-00-16 (160-25126-16). The reporting limits have been elevated by the appropriate factor.

The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) associated with batch analytical batch 160-333039: Acetone, 2-Hexanone, n-Butanol, 4-Methyl-2-pentanone, and 2-Butanone. A low level CCV was analyzed at the base reporting limit of 1ug/L and the affected analytes were detected. Target analytes recovering above the reporting limit were qualified and reported: (CCVIS 160-333039/4).

The continuing calibration verification (CCV) associated with batch 160-333039 recovered outside acceptance criteria, low biased, for Bromomethane, 2-Hexanone, and n-Butanol. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data was reported.

10 With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control 11 limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, 12 the reporting limits are adjusted relative to the dilution required.

13 TestAmerica St. Louis attests to the validity of the laboratory data generated by TestAmerica facilities reported herein. All analyses performed by TestAmerica facilities were done using established laboratory SOPs that incorporate QA/QC procedures described in the application methods. TestAmericas operations groups have reviewed the data for compliance with the laboratory QA/QC plan, and data have been found to be compliant with laboratory protocols unless otherwise noted below.

The test results in this report meet all NELAP requirements for parameters for which accreditation is required or available. Any exceptions to NELAP requirements are noted in this report. Pursuant to NELAP, this report may not be reproduced, except in full, without the written approval of the laboratory.

Calculations are performed before rounding to avoid round-off errors in calculated results.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below.

All solid sample results for Chemistry analyses are reported on an "as received" basis unless otherwise indicated by the presence of a %

solids value in the method header. All soil/sediment sample results for radiochemistry analyses are based upon sample as dried and disaggregated with the exception of tritium, carbon-14, and iodine-129 by gamma spectroscopy unless requested as wet weight by the client.

This laboratory report is confidential and is intended for the sole use of TestAmerica and its client.

The continuing calibration verification (CCV) associated with batch 160-334197 recovered above the upper control limit for 5

Chloromethane. The samples associated with this CCV had no detections for the affected analyte; therefore, the data was reported:

(CCVIS 160-334197/2). 6 Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 7 160-334208 and analytical batch 160-334197. An LCS/LCSD was prepared to demonstrate accuracy and precision: (MB 160-334208/1-A). 8 Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 160-334129 and analytical batch 160-334995. LCS/LCSD performed to demonstrate accuracy and precision: (MB 160-334129/3-A).

9 The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) 10 associated with batch 160-334995: Acetone, n-Butanol, and 2-Butanone (MEK). A low-level LOQV was analyzed at the reporting limit (5ug/L) and the affected analytes were detected. T arget analytes recovering above the reporting limit were qualified and reported: (CCVIS 11 160-334995/2).

The continuing calibration verification (CCV) associated with batch 160-334995 recovered outside acceptance criteria, low biased, for 12 Chloromethane. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data was reported: (CCVIS 160-334995/2). 13 The continuing calibration verification (CCV) associated with batch 160-334995 recovered outside acceptance criteria, low biased, for Vinyl chloride. A reporting limit (RL) standard was analyzed, and the target analyte was detected. All but one of the associated samples were non-detect for this analyte; therefore, the data was reported. The sample with Vinyl chloride detected was re-analyzed for Vinyl chloride only: (CCVIS 160-334995/2).

Tetrachloroethene analyzed in preparation batch 160-334208 and analytical batch 160-334197 was detected in sample 4362-SS-171019-02 (160-25151-2) at a level (340ppb) above the upper calibration limit (200ppb) for a low-level soil analysis. The sample was re-analyzed as a medium-level solvent extraction, but Tetrachloroethene in this analyses was detected at only 140ppb, which was below the reporting limit (330ppb) for this method. The remaining sample vial was analyzed, again using the low-level soil analysis, to compare to the first two results. The low-level soil re-analysis yielded another result (250ppb) above the upper calibration limit. These results indicate a sample matrix which is non-homogeneous. The result from the original analysis was reported with the qualifier for a result above the upper calibration limit.

The following compounds did not meet the minimum relative response factor limits in the continuing calibration verification (CCV) associated with batch analytical batch 160-333039: Acetone, 2-Hexanone, n-Butanol, 4-Methyl-2-pentanone, and 2-Butanone. A low level CCV was analyzed at the base reporting limit of 1ug/L and the affected analytes were detected. Target analytes recovering above the reporting limit were qualified and reported: (CCVIS 160-333039/4).

The continuing calibration verification (CCV) associated with batch 160-333039 recovered outside acceptance criteria, low biased, for Bromomethane, 2-Hexanone, and n-Butanol. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non-detect for this analyte, the data was reported.

The laboratory control sample (LCS) for analytical batch 160-333039 recovered outside control limits for the following analytes:

Bromomethane. A low-level LCS (LLCS), spiked at the reporting limit (RL), was prepared with this batch. The affected target analyte recovered within acceptance limits. Since the affected target compound was not detected in the samples, the data was reported and qualified: (LCS 160-333039/5) and (LCSD 160-333039/6).

Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate/sample duplicate (MS/MSD/DUP) associated with analytical batch 160-333039. LCS/LCSD were performed in order to demonstrate accuracy and replicate-precision: (LCS 160-333039/5) and (LCSD 160-333039/6).
