摘要

Deep geological disposal with provisions for retrieval is one of the most promising strategies for the definite management of high-level nuclear waste. However, retrieval of disposed waste might require certain extensive work of personnel near the waste package that might also enhance the level of radiation exposure. Hence, a precise estimation of the personal dose with consideration of realistic body postures is highly desired for optimization of individual working scenarios. In this study, the near field of a generic geological disposal facility was modeled with a horizontal emplacement drift in saline host rock. Inside the drift, a shielded disposal cask loaded with spent nuclear fuel was placed on the ground. A whole-body stylized phantom with moveable limbs was applied to represent a reference worker. Several relevant realistic body postures that might be encountered in a disposal facility were investigated. The corresponding radiation exposure was calculated and compared with a general-purpose Monte Carlo code. (C) 2021 Elsevier Ltd. All rights reserved.
