CLINCH RIVER SMR PROJECT AMEC PROJECT No. 6468-13-1072 SLUG TEST DATA REPORT Observation Well OW-1 01 U Test Method: ASTM D 4044-96 (2008), Sections 8 and 9 Test Type: Pneumatic Test Dates: 9/15/2013; 9/16/2013 Well Construction Diagram Plots: Background water level for rising head test Rising head test Background water level for falling head test Falling head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data. 101 UBR 2013-09-15 10-52.44 (contains background and pressurization/equalization data for rising head test) 101 UR 2013-09-15 10.49.20 (contains test data for rising head test) 101 UBF 2013-09-16 10.43.51 (contains background and vacuum/equalization data for falling head test) 101UF 2013-09-16 14.04.03 (contains test data for falling head test) Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.

2. Static water level (below top of casing) prior to testing = 20.84 ft.

3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.

4. Water level changes during tests are represented by changes in the height of water above the transducer.

CLINCH RIVER SMR PROJECT AMEC PROJECT No. 6468-13-1072 SLUG TEST DATA REPORT Observation Well OW-202L Test Method: ASTM D 4044-96 (2008), Sections 8 and 9 Test Type: Solid Test Dates: 9/29/2013; 9/30/2013; 10/2/2013 Well Construction Diagram Plots: Background water level for solid slug falling head test (see note 1 below) Falling head test Background water level for rising head test Rising head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data. 202LBF 2013-09-29 17.00.37 (contains background data for falling head test) 202LF 2013-09-30 07.57.06 (contains test data for falling head test) 202LBR 2013-09-30 08.41.00 (contains background data for rising head test) 202LR 2013-10-2 07.29.44 (contains test data for rising head test) Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background" file prior to initiating a test. For this test, an unexplained increase in water level between ending the background check and starting the falling head test occurred. The data for the background file is considered questionable. AMEC recommends using the portion of the falling head test file immediately prior to the slug insertion to obtain the reference head for the test analysis.

2. Static water level (below top of casing) prior to testing = 48.21 ft.

3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.

4. Water level changes during tests are represented by changes in the height of water above the transducer.

5. A pneumatic test was attempted, but the well was not holding pressure.

The test method was changed to the solid slug method. Clinch River Data Report Rev. 4 CRP-1112.16 Page E.4-23 of 185 Prepared by/Date: f2:M 4/.i ),a-Checked by/Date: C!"PT?! /c;/19-

1.

Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.

2. Static water level (below top of casing) prior to testing = 72.08 ft.

3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.

4. Water level changes during tests are represented by changes in the height of water above the transducer.

The Excel files also contain the plots listed above that AMEC created from the recorded data. 418UBR 2013-09-28 14.10.21 (contains background and pressurization/equalization data for rising head test) 418UR 2013-09-28 15.13.03 (contains test data for rising head test) 418UBF 2013-09-28 16.33.05 (contains background and vacuum/equalization data for falling head test) 418UF 2013-09-2817.16.39 (contains test data for falling head test) Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted.

2. Static water level (below top of casing) prior to testing = 61.92 ft.

3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.

4. Water level changes during tests are represented by changes in the height of water above the transducer.

1.

Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background and pressurization (or vacuum)/equalization file prior to initiating a test; only that time frame from the "background" file is plotted for pneumatic tests.

2. Static water level (below top of casing) prior to testing = 64.88 ft on 9/30/13 and 64.77 ft on 1 0/1/13.

3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.

4. Water level changes during tests are represented by changes in the height of water above the transducer.

5. The well would not hold a vacuum; the test method was changed to the solid slug method, and the transducer was lowered to accommodate the solid slug.

CLINCH RIVER SMR PROJECT AMEC PROJECT No. 6468-13-1072 SLUG TEST DATA REPORT Observation Well OW-429U Test Method: ASTM D 4044-96 (2008), Sections 8 and 9 Test Type: Solid Test Dates: 11/19/2013; 11/20/2013 Well Construction Diagram Plots: Background water level for falling head test Falling head test Background water level for rising head test Rising head test Copies of transducer electronic files in Excel (.xlsx) and native (.wsl) format as listed below are provided under separate cover as supporting information for this data report. The Excel files also contain the plots listed above that AMEC created from the recorded data. 429UBGF 2013~11~19 08.37.46 (contains background data for falling head test) 429UF 2013~11-19 08.38.25 (contains test data for falling head test) 4.29UBGR 2013-11-19 08.38.38 (contains background data for rising head test) 429UR 2013-11-20 08.40.53 (contains test data for rising head test) Notes:

1. Water level trend prior to testing is represented by the initial five minutes (minimum) of transducer recording in the "background file prior to initiating a test.

2. Static water level (below top of casing) prior to testing = 37.15 ft.

3. The depth to static water level below top of casing prior to initial testing and the height of water above the transducer at the initial reading are added to provide the depth of the transducer below the top of the well casing reference point.

4. Water level changes during tests are represented by changes in the height of water above the transducer.
