OSTI ID:774469
Two-dimensional discrete ordinates shielding calculations have been performed for the Spallation Neutron Source (SNS) beam lines. The calculations include simulation of the T{sub 0}, E{sub 0}, and Bandwidth choppers, and a generic straight beam line. The purpose of these calculations was to perform exploratory analyses to estimate the minimum shielding required to reduce personnel doses to {approximately}0.25 mRem/h. For source distances up to 10 m, a combined steel and concrete shielding thickness of up to {approximately}2 m is required to reduce the dose to {approximately}0.25 mRem/h.
