Survey Report OL1-6 Trench (GPU Nuclear Letter E910-05-052 comments from ORISE Letter dated August 11, 2005)

3) In Appendix A-I the Microshield model is slightly different than those of other reports. Different cases may involve calculations of gamma flux in different models.

Microshield calculations are then repeated in order to provide appropriate conversion factors. Engineering judgment is used in all of these cases to develop appropriate model conditions. In this case, the difference between 1 1 -inch radius and 1. 1 -inch radius produces a 1% difference in the MDCscan for the assumed source. This difference is trivial compared to the variance associated with the judgment involved in developing the models and changes in assumptions that are case -to case and then comparing that to the actual surfaces scanned. No changes to the report are needed.
