[Global] [External] Dry Cask Campaign Exposure

[Mingus, Cris S]

Davis-Besse's last dry cask campaign was in 2019. We loaded 8 casks with average of 44.61 KW. Average was 612 mRem. We installed an additional 5 shielding packages for 2019 than previously. From what we observed, dose rates are not linear as the energy level goes up. We were seeing up to an order of magnitude greater dose rates than we saw in 2017 depending on the survey points. Our 2017 campaign averaged 22.3 KW and 142 mRem for 4 casks.
