摘要:
Understanding the distribution of radionuclides from uranium mine tail gas into the surface atmosphere is one way of dealing with radioactive pollution, but the factors affecting the concentration distribution are considered insufficiently studied. This article looks into the structural characteristics of the exhaust shaft of a uranium mine and studied the effect of the cross-sectional shape (square or round) on radionuclide concentrations. We used numerical simulation to verify the significance and clarity of the impact. The results show that, without considering the terrain, the radionuclide concentration distribution is not sensitive to wind direction at different heights, regardless of exhaust shaft shape. There are 2–5 times more radionuclides discharged from the round exhaust shaft as the square shaft, and the difference increases with height. The concentration exceeds the maximum dose requirement until approximately 500 m downwind when the square exhaust shaft is used, while it is at least 1000 m with the round exhaust shaft. These conclusions imply that the structural features of the exhaust shafts, especially the cross-sectional shape, should be given high priority during construction, and the structure of the exhaust shafts should not be neglected or oversimplified in the study of similar problems. © The Author(s) 2018.

摘要:
Radon diffusivity is a key parameter for estimating radon emanation from porous media. We have developed a Monte Carlo method for determining radon diffusion coefficients in porous media. In the proposed method, the probability model for pore diameter derived from fractal theory is used to describe the microscopic pore structure of porous media. The Monte Carlo technique is utilized to search for the pore size that satisfies the probability model for porous media. The convergence rate of the proposed is fast (∼3 min). Radon diffusion coefficients measured by the closed chamber method are used to validate the accuracy of the proposed method. © 2019 Elsevier Ltd

摘要:
介绍了某铀浓缩厂含铀放射性废物管理现状及放射性废物最小化方面的应用实践。放射性废物分类收集,集中处置,减少放射性废物的体积及产生量是基本要求。采用5%的Na2CO3和30%H2O2混合液以及清水对放射性污染管道、阀门等进行清洗,使α表面污染≤0.4 Bq/cm2,清洗液厂内循环利用。通过除锈清洗液再利用、水压试验水再利用及容器清洗工艺优化改进等措施,单台容器平均废液产生量减少35%左右,从源头上控制了含铀废液的产生量。小容器处理工艺由湿法改为干法,废水产生量减少了90%;大容器清洗过程中,除锈液可重复利用5次,可使得除锈废液的产生量减少80%左右。提高吸附尾液循环利用比,减少了废水的产生量。采用钙盐联合沉淀法处理废水,废渣年产生量平均减少20%,废水处理合格率大大提高。在此基础上,介绍了实现含铀放射性废物最小化的几点思路,并提出相关措施。

摘要:
将氧化铋以粉末形式添加到普通混凝土中,制备出绿色无污染且具有良好的?射线屏蔽性能的掺杂氧化铋的混凝土。相较于普通混凝土,氧化铋-混凝土的屏蔽性能及力学性能均得到改善。对比屏蔽性能实验结果及MCNP5(Monte Carlo N-Particle 5)模拟结果,二者相符很好,可以用MCNP5进行后期配合比设计优化。运用田口方法对水泥量、水胶比、氧化铋比例及砂率等进行优化设计。结果表明,对氧化铋-混凝土屏蔽能力影响最大的参数是氧化铋的加入量,其次为水泥量,水胶比及砂率的影响可忽略。

摘要:
Concrete has a proven ability to attenuate gamma rays and neutrons without compromising structural property;therefore, it is widely used as the primary shielding material in many nuclear facilities. Recently, there is a tendency toward using various additives to enhance the shielding properties of these concrete mixtures. However, most of these additives being used either pose hygiene hazards or require special handling processes. It would be ideal if environmentally friendly additives were available for use. The bismuth oxide (Bi<inf>2</inf>O<inf>3</inf>) additive shows promise in various shielding applications due to its proven radiation attenuation ability and environmentally friendly nature. To the best of our knowledge, however, Bi<inf>2</inf>O<inf>3</inf>has never been used in concrete mixtures. Therefore, for this research, we fabricated the Bi<inf>2</inf>O<inf>3</inf>-based concrete mixtures by adding Bi<inf>2</inf>O<inf>3</inf>powder in the ordinary concrete mixture. Concrete mixtures with lead oxide (PbO) additives were used for comparison. Radiation shielding parameters like the linear attenuation coefficients (LAC) of all these concrete mixtures showing the effects of the Bi<inf>2</inf>O<inf>3</inf>additions are presented. The mechanical performances of concrete mixtures incorporated with Bi<inf>2</inf>O<inf>3</inf>additive were also investigated. It suggested that the concrete mixture containing 25% Bi<inf>2</inf>O<inf>3</inf>powder (B5 in this study) provided the best shielding capacity and mechanical performance among other mixes. It has a significant potential for application as a structural concrete where radiological protection capability is required. ©2016 Elsevier Ltd
