Evaluation and simulation analysis of China's copper security evolution trajectory

Copper metal is one important raw material of national economy, and its security is tightly linked with industrialization process. A comprehensive security evaluation index system, including three first class indicators, nine second class indicators and fourteen third class indicators, was constructed based on the pressure-state-response （PSR） model. And efficacy coeff^cient method was adopted in dimensionless treatment and entropy method was used to obtain the weight. Then, the data of China＇s copper from 1992 to 2011 were studied and collected. By processing these data, a comprehensive safety index of China＇s copper was got. The results showed that the comprehensive safety index of China＇s copper rose from its low point. The safety pressure state of China＇s copper was improved. The safety state of China＇s copper continued to be tight. The response state continued to rise. The overall situation of China＇s copper safety was improving, but still not optimistic.

A Study on Spatial Variation of Water Security Risks for the Zhangjiakou Region

Zhangjiakou region is situated in an agro-pastoral ecotone with a fragile ecosystem. While it has limited surface water resources available and serious groundwater over-exploitation, the city is located in the water conservation zone for the Beijing-Tianjin-Hebei coordinated development area, so its water security is crucial for the entire Beijing-Tianjin-Hebei region. Therefore, it is of vital significance to determine the zoning management of water resources and decision-making according to the magnitude of water resource security risks. This study built an indicator system for water security risk assessment in line with the principles of scientific validity, comparability, operability, and data availability, and this system gives weights to these indicators using the AHP approach. County-level multi-source data for the study area, based on water resource zones, were collected by using mathematical statistics and 3 S technology. With normalized data and a weighting method the water security risks were calculated. The results showed large spatial variations of water security risks in Zhangjiakou on the scales of geomorphic and administrative units as well as river basins. High-risk areas are extensive in the Bashang Plateau, and extremely high risk values are found in the Baxia areas. On the watershed scale, high-risk areas are mainly distributed in the inland river basins and the Yongding River basin. The risk values of the Luanhe River, Chaobai River and Daqing River basins in the Zhangjiakou region tend to decrease from north to south. For the northern and western areas of the Bashang Plateau, the factor of "vulnerability of the disaster-prone environment" contributes the most to the water security risk level. Agricultural water use constrains industrial and ecological water use, but in the context of inadequate water resource endowments, the urban population concentration and industrial development are the main causes of water shortages and water pollution so they contribute more to water security risks. This study of the spatial variation of water security risks in Zhangjiakou can provide an important scientific reference for zone-based management and decision-making for reducing the water security risks in the farming-pastoral ecotone.

Safety Evaluation of Sustainable Uranium Development in China Combined with an Analytical GAN Framework

Uranium is the basic raw material for nuclear energy and is quite highly regarded.Developing a safe supply of uranium is important for safeguarding sustainable nuclear development.The purpose of this study is to evaluate the sustainability of uranium development in China based on dynamic system modeling combined with GAN(Generative Adversarial Network)analysis.We considered eight essential indicators and 42 sub-indicators as part of a detailed quantitative description,and then developed a framework to evaluate and rank China-specific sustainability in light of the quantitative performance of five options for fuel cycle transition scenarios.We began by using KMO sample measurements and the Bartlett Test of Sphericity to determine the suitability of factor analysis and the fitness of the corrected model map and observation data.We then analyzed the roles of different representatives of the decision makers and their impacts on the overall ranking by applying GAN methods from a weighted perspective.Five transition scenarios identified are 1)Pressurized Heavy Water Reactors,2)Mixed Light Water Reactor+Fast Reactor,3)Mixed LWR+FR fuel cycle scheme with heterogeneous irradiation,4)Mixed Pressurized Water Reactor+FR fuel cycle scheme with plutonium recycled directly and repeatedly,and 5)Sodium-cooled fast breeder reactor power plant.The results showed that scenario 1 is the most unsustainable and highly confrontational scenario with a high demand for uranium resources,the lowest sustainability and a high level of antagonism among departments.On the other hand,Scenario 5 requires more advanced technology but exhibits less antagonism among the departments,and thus it largely satisfies the basic requirements for uranium sustainability and low levels of antagonism.In this paper,a safety assessment index system for the uranium supply is computed using a GAN framework.This system plays a crucial role in the sustainable supply and development of uranium,and provides flexibility for coping with the evolution and inherent uncertainties of the necessary technological developments.
