Abstract

The Institute for Nuclear Research and Nuclear Energy at the Bulgarian Academy of Sciences is working on the construction of a cyclotron centre. The facility is on a design level. At this stage of the project, an important task is the radiation shielding assessment of the facility. Nowadays, the Monte Carlo transport codes have become the tool of choice for solving this type of problem. In the current paper, the transport code FLUKA is used for the calculations. It is widely applied for shielding design and analysis of accelerators and their components. The distributions of the radiation fields inside and outside the cyclotron bunker are presented in this paper. Both different irradiation scenarios and bunker configurations are considered in the conducted Monte Carlo simulations. These results will be used as a guidance in site planning.

内巴斯回旋加速器设施的辐射屏蔽及剂量评估
保加利亚科学院的核研究和核能研究所正在建造一个回旋加速器中心。该设施处于设计水平。在工程的这一阶段,一项重要的任务是对设施的辐射屏蔽评估。如今,蒙特卡洛运输代码已成为解决这类问题的首选工具。本文采用传输码FLUKA进行计算。它广泛应用于加速器及其部件的屏蔽设计和分析。本文给出了回旋加速器掩体内外辐射场的分布。在进行的蒙特卡罗模拟中,考虑了不同的辐照情景和掩体结构。这些结果将作为场地规划的指导。
