Abstract
This paper began by presenting a summary of bunker shielding analyses that considered all beamlines populated or all beamlines unpopulated. This analysis led to the concern that populated beamlines next to unpopulated beamlines might increase the total effective dose rate outside the bunker to exceed the 0.25 mrem/h limit because unpopulated beamlines do not have any beamline shielding installed outside the bunker. The analysis indicated that this concern was valid, but the increase above 0.25 mrem/h was not substantial and was limited to a relatively small region. Before the STS final design is completed, the shielding design of the bunker wall and beamline shielding must be refined to reduce the total effective dose rate that exceeds 0.25 mrem/h for an unpopulated beamline next to populated beamlines.
