At Fort Calhoun we did not put up additional shield since there was no streaming radiation contributing to the total dose. The only shielding used was on the Dry cask itself for performing welding.

For example, at Palo Verde during dry cask storage campaigns workers in the Cask Load and Washdown Pits get a significant amount of dose from the adjacent Spent Fuel Pool. During mostly due to shine / streaming through the Weir gates that separate the areas. Question for this utilities with similar configurations, have you considered or do you shield these areas?
