In some cases, the initial and/or final one to two blows produced poor quality data, and were not used to calculate the Average Measured Energy. EFV = EMX

  • 1000 lbslkip, where EMX equals the transferred energy measured by the PDA (see attached PDA data).

bEnergy Transfer Ratio is the Measured Energy divided by the theoretical SPT energy of350 foot-pounds (140 pound hammer falling 2.5 feet).

Only blows used to calculate N-values were considered per ASTM D4633-10. In some cases, the initial and/or final one to two blows produced poor quality data, and were not used to calculate the Average Measured Energy. EFV = EMX

  • 1000 lbs/kip, where EMX equals the transferred energy measured by the PDA (see attached PDA data).

bEnergy Transfer Ratio is the Measured Energy divided by the theoretical SPT energy of350 foot-pounds (140 pound hammer falling 2.5 feet). The average EFV and ETR values may differ slightly and insignificantly from those in the PDIPLOT tables due to roundoff. Prepared By: V"k.. Date: -l0-1 c.f Checked By: <;k_ Date: Ho-I~ 0

Report of SPT Hammer Energy Measurements M&W Drilling Diedrich D-120 Drill Rig Rig Serial No. 027 Automatic Hammer Clinch River SMR Site AMEC Project No. 6468-13-1072 AMEC Environment & Infrastructure, Inc. (AMEC) is pleased to present the results of Standard Penetration Test (SPT) hammer energy measurements for the subject drill rig at the Clinch River SMR site in Oak Ridge, Tennessee. This report summarizes the field testing activities and presents the results of the hammer energy measurements. SPT Hammer Energy Field Measurements SPT energy measurements were made at the referenced site on June 6, 2013. A separate boring from the planned exploratory borings was used (test hole #7 near MET Tower). Per an approved deviation request, testing was performed at depths shallower than those recommended in ASTM D4633-10 due to the presence of relatively shallow rock at the site. The testing was performed by Michael Hamilton, an AMEC representative, from approximately 9:30AM to 11 :00 AM under cloudy skies and an air temperature of about 64 degrees Fahrenheit. The boring was drilled with personnel and equipment from M&W Drilling. The drilling equipment consisted of a Diedrich D-120 drill rig with an automatic SPT hammer. The drilling tools consisted of AW-J sized drilling rods and a 2-foot long split tube sampler. The drill rig operator during sampling was Gary Akins. Energy measurements were recorded during sampling at the depth intervals shown in Table 1. The energy measurements were performed with a SPT Analyzer (Serial No.3622L) with SPT Analyzer software, accelerometers (Serial Nos. K3370 and K1050) and strain gages (Serial Nos. 75 AW-1 and 75 AW-2). A steel drill rod, 2 feet long and instrumented with dedicated strain gages, was inserted at the top of the drill rod string immediately below the SPT hammer anvil. The inserted rod was also instrumented with two piezoresistive accelerometers that were bolted to the outside of the rod. The instrumented rod insert had a cross-sectional area of approximately 1.21 square inches and an outside diameter of approximately 1.75 inches at the gage location. The drill rods included in the drill rod string were hollow rods in 5-to 1 0-foot long sections, with outside Correspondence: AMEC Environment & Infrastructure, Inc. 2801 Y orkmont Road Suite 100 Charlotte, North Carolina 28208 Tel (704) 357-8600 Fax (704) 357-8638 Clinch River Data Report Rev. 4 CRP-1112.16 Page 8.2-143 of 168 arnec.com RCN: CRP-1215.0 Page 1 c:D of 165

Due to the closed hammer system, the hammer lubrication condition could not be observed. Testing was performed with the rig running at multiple engine speeds at the request of the field site manager in order to determine the effects (if any) of engine speed on the energy transfer ratio. The normal operating speed used for this drill rig by the driller is approximately 2,000 RPMs. Engine speeds of approximately 1,500 and 2,500 RPMs were also tested for information purposes only and are presented herein. Calibration Records The calibration records for the equipment associated with this testing are filed in the project record control center. The calibration services were procured and approved in accordance with the commercial grade dedication process as outlined in AMEC's nuclear quality assurance program. Calculations for EFV The work was performed in accordance with ASTM D 4633-10. The strain and acceleration signals were converted to force and velocity by the PDA. The maximum energy transmitted to the drill rod string (EFV), as measured at the location of the strain gages and accelerometers, was calculated by the SPT Analyzer using the equation shown below: EFV = f F(t)

  • V(t)
  • dt Where: EFV = Transferred energy (EFV equation), or Energy of FV F(t) = Calculated force at timet V(t) = Calculated velocity at time t As recommended by ASTM D 4633-10, the force-velocity method of energy calculation was used. The equation shown above for calculating EFV, integrated over the complete wave event, measures the total energy of the event using both force and velocity measurements. The EFV values associated with each blow analyzed are tabulated in the attached PDIPLOT tables and are also shown graphically in the PDIPLOT charts.

Calculations for ETR The ratio of the measured transferred energy (EFV) to the theoretical potential energy of the SPT system (140 lb weight with the specified 30 inch fall) is the ETR. The ETR values (as a percentage of the theoretical value) are shown in Table 1. Comparison of ETR to Typical Energy Transfer Ratio Range Based on a research report published by the Florida Department of Transportation (FOOT) (Report WPI No. 0510859, 1999), the average ETR measured for automatic hammers was 79.6%. The standard deviation was 7.9%; therefore, the range of ETRs within one standard deviation of the average was reported to be 71.7% to 87.5%. This range of ETRs was also consistent with other research that was cited in the FOOT research paper; however, maximum and minimum ETR values of up to 98% and 56%, Clinch River Data Report Rev. 4 CRP-1112.16 Page 8.2-144 of 168 RCN: CRP-1215.0 Page 1 D1 of 165

SPT Energy Measurements-M&W Drilling Diedrich D-120 Drill Rig AMEC Project No. 6468-13-1072 January 10, 2014 Page3 respectively, were reported in the literature. The ETR values shown in Table 1 are within the range of typical values for automatic hammers as reported in the literature. Evaluation and Conclusions Based on the field testing results, our evaluation and conclusions from the SPT energy measurements are summarized below: The average energy transferred from the hammer to the drill rods for each individual depth interval ranged from 309 foot-pounds to 340 foot-pounds. These average energy transfers correspond to energy transfer ratios (ETR) of 88% to 97% of the theoretical energy (350 foot-pounds) of the SPT hammer. The average at each depth interval was calculated as the transferred energy for each analyzed blow at the depth interval divided by the total number of hammer blows analyzed. The overall average energy transfer of the SPT system (for all the depth intervals tested) was 331.3 foot-pounds, with an average ETR of 94. 7%. The above measurements are for the hammer running at 2,000 RPMs which is the engine speed under normal operating conditions.

Only blows used to calculate N-values were considered per ASTM 04633-10. In some cases, the initial and/or final one to two blows produced poor quality data, and were not used to calculate the Average Measured Energy. EFV = EMX

  • 1000 lbs/kip, where EMX equals the transferred energy measured by the PDA (see attached POA data).

bEnergy Transfer Ratio is the Measured Energy divided by the theoretical SPT energy of350 foot-pounds (140 pound hammer falling 2.5 feet). The average EFV and ETR values may differ slightly and insignificantly from those in the PDIPLOT tables due to roundoff. Prepared By: \\k Date: l - 1 D - I c.\\ Checked By: 9L Date: Ho-ll..j

Only blows used to calculate N-values were considered per ASTM D4633-10. In some cases, the initial and/or final one to two blows produced poor quality data, and were not used to calculate the Average Measured Energy. EFV = EMX

  • 1000 lbs!kip, where EMX equals the transferred energy measured by the PDA (see attached PDA data).

bEnergy Transfer Ratio is the Measured Energy divided by the theoretical SPT energy of350 foot-pounds (140 pound hanuner falling 2.5 feet). The average EFV and ETR values may differ slightly and insignificantly from those in the PDIPLOT tables due to roundoff.

Only blows used to calculate N-values were considered per ASTM D4633-10. In some cases, the initial and/or final one to two blows produced poor quality data, and were not used to calculate the Average Measured Energy. EFV = EMX

  • 1000 lbslkip, where EMX equals the transferred energy measured by the PDA (see attached PDA data).

bEnergy Transfer Ratio is the Measured Energy divided by the theoretical SPT energy of350 foot-pounds (140 pound hammer falling 2.5 feet). The average EFV and ETR values may differ slightly and insignificantly from those in the PDIPLOT tables due to roundoff. Prepared By: Date: \\ -\\'C... \\4 Checked By: CJu_ Date: l-lo-lY
