Spent LIBs contain not only dangerous heavy metals but also toxic chemicals that pose a serious threat to ecosystems and human health. Therefore, a great deal of attention has been paid to the development of an efficient process to recycle spent LIBs for both economic aspects and environmental protection. In this paper, we review the state-of-the-art processes for metal recycling from spent LIBs, introduce the structure of a LIB, and summarize all available technologies that are used in different recovery processes. It is notable that metal extraction and pretreatment play impor- tant roles in the whole recovery process, based on one or more of the principles of pyrometallurgy, hydrometallurgy, biometallurgy, and so forth. By further comparing different recycling methods, existing challenges are identified and suggestions for improving the recycling effectiveness can be proposed.展开更多

This stage is to test the work results of the normal work of the nuclear power plant, and provide certain guidance for the subsequent problem correction of the nuclear power plant. The preparation of the production plan can ensure that the entire control process is more optimized and reasonable, and provide certain reference for the subsequent new expansion of the nuclear power plant. This paper mainly introduces the research background, practical demonstration and relevant management methods of the safe production of nuclear power plants, hoping to provide some reference for the subsequent safe production of nuclear power plants.展开更多

It is also a very important part of the production of nuclear power plants and must be paid attention by all departments. The planning management involved in the production preparation stage needs to be discussed level by level to ensure the efficient operation of the subsequent nuclear power production preparation plan. This paper mainly discusses the overall planning management system of nuclear power production preparation, from the aspects of planning preparation, tracking management and optimization suggestions, etc., which provides a certain reference for the subsequent commissioning of new nuclear power plant projects.展开更多

Today, with the continuous improvement of the market economy system, the old nuclear power production plan management system cannot meet the market demand and the demand of various industries. For the safe operation of enterprises, nuclear power production provides an important basic guarantee. In view of this, based on the complexity of the content of nuclear power production preparation plan, this paper briefly describes the optimization strategy of the preparatory work and the management work in the later stage, so as to promote the steady development of nuclear power industry.展开更多
