This Class 1 structural material survey design is found in SNEC calculation E900 004 (Reference 3.1). Static measurement survey results were collected and summarized under SR-0115 (Reference 3.2) (see survey summary in Attachment 1-1 to 1-4). These results were originally assessed by SNEC personnel and reviewed by SNEC contractor

'CoPhysics' via e-mail transmittal (see Attachment 2-1). However, the original assessment was not written up in the form of a calculation IAW the requirements of the SNEC LTP. This-calculation serves to more properly complete the documentation of this survey work.

'Over-lap between measurement points resulted in more measurements than the total number of linear feet of Unistrut.

2.1.1 Actual background values measured in the CV Tunnel are provided in Table 2.

These values are lower then the original SD planning value used, and therefore provide a lower MDCstatic value when combined with the actual Nal survey instrument conversion efficiency of 209,862 cpm/mR/h (see Attachment 3-1 to 3-2).

Even though this is a conservative change, it may not be the appropriate value if most of the activity is on the exterior exposed surface of each one foot section of Unistrut where there is no attenuation impact. However, using this value provides an upper bounding limit for this estimate.

2.2 Conclusion Measurements and smear sampling efforts indicate that surface concentrations in dpml1 00 cm 2 when averaged over one foot lengths of Unistrut, are well below the allowable limit for this survey unit (see Attachment 1-1 to 1-4 for smear results). Static measurement results are calculated and presented in Attachment 5-1 through 5-3. A worst case scenario is prepared by comparing the 2 sigma plus the mean concentration to the actual DCGLw value. These percent of DCGLw values are listed in the last column of each data sheet (Attachment 5-1 to 5-3). The maximum concentration calculated for each of the three surfaces is provided in Table 1. No statistical testing is required since all results are well below the effective DCGLw.

SR NUMBER SR-1 15 AREA/LOCATION CV Tunnel Uni-strut SPECIFIC SAMPLING I SURVEY INSTRUCTIONS OR COMMENTS RESULTS

SUMMARY

FOR SR-115 SR-1 15 was issued to perform FSS of the embedded uni-strut in the CV Tunnel. There is approx. 70.5 linear feet of uni-strut. The survey unit covered under this SR is SS22-5. The SR required the following radiological measurements:

  • Static Measurements Using a Sodium Iodide Detector - perform both a group of background counts (10-minute) and static measurements on the uni-strut spaced in 1-foot increments. These measurements shall be taken at a distance of 2 inches for 2 minutes.
  • Loose Surface Contamination (Smear Survey) - obtain at least one smear sample from each section of uni-strut following the static measurement.
  • QC Repeat Measurements - as a minimum, 5% of all measurements and sampling will be re-performed and analyzed using identical methodology and IAW E900-IMP-4520.04.
1. Summary of Static Measurements A. Background Measurements Nine background static measurements were obtained (three measurements on both North and South Walls and the Ceiling).

Results: The background measurements ranged from 85.4 to 101.2 cpm. The following table lists the static measurement results:

Review of Unistrut Calculations

Dear Barry:

I have reviewed your calculations contained in the spreadsheet you sent via email on 5/14/04. All calculations and methods are correct. I see in the column labeled "Estimated 2s Uncertainty" that an extra 10% uncertainty was added. I assume this was for calibration, geometry and other uncertainties. Perhaps this should be footnoted. Also, in the column labeled 'Max % of Limit", I recommend that additional description be added so that the reader understands that this is the result plus 2-sigma. Perhaps: uMax % of Limit at 2-sigma". Or, add a footnote to that effect.

If you want to discuss the calculations further, please call me anytime.

Best regards, Theodore E. Rahon, Ph.D., CHP President encl.

FINAL NOTE: Suggested changes as noted above incorporated into previous results 5/20/04 by BHB.
