Bulk Biological Shielding Aspects of the Yankee Core

The analysis of the radiation sources within the primary concrete shielding of the Yankee Atomic Electric Plant is summarized The dose due to these sources at a point on a transverse centerline and outside the plant container was calculated. The dose at two points on the axial centerline was found as well as the extent to which the water is actiwated during its passage through the pressure vessel. (auth)
