邯郸邢台地X矿山排水与利用

邯郸邢台地区煤、铁资源丰富,矿山排水量大,大量矿坑排水不仅造成地下水资源的严重浪费,而且污染环境,另一方面,该区工农业用水又十分紧缺,大量的矿山排水使排供矛盾更加突出,加剧了水资源的危机。邯郸邢台地区煤矿、铁矿年总排水量为24933.15×104m3/a,利用水量为8357.70×104m3/a,占年总排水量的34%;剩余水量为16575.45×104m3/a,占年总排水量的66%。该区矿坑排水量大,剩余水量较多,因此进一步开发利用的潜力较大。从水质上看,邯郸邢台地区的矿坑排水大多属于含悬浮物矿井水,需要进行净化处理才能利用。处理后的矿坑水可用于工业、农业、生活以及景观绿化用水等。

Recent Waste Management Related Developments in Germany

The Federal Republic of Germany intends to dispose of all types of radioactive waste in deep geological formations. This waste comprises spent fuel elements, vitrified fission products, nuclear power plant operational and decommissioning waste as well as spent sealed radiation sources and miscellaneous waste originating from small waste generators. The Federal Government made a pronounced change in energy policy since 1998, the most important feature of which is the abandoning or phasing out of nuclear energy, finally set in force by the April 2002 amendment of the Atomic Energy Act. According to the new approach to waste management and disposal, further sites in various host rocks shall be investigated for their suitability. A special expert group was set up to develop repository site selection criteria and respective procedures on a scientifically sound basis. The objective of the site selection procedure is to identify—with public participation—potential disposal sites in a comprehensible and reliable way. Step by step and based on the said criteria, those areas, site regions and eventually sites shall be selected, which offer particularly favourable conditions for the later demonstration of the final site's suitability and its confirmation in a licensing procedure.

Quantification of margins and uncertainties: Example analyses from reactor safety and radioactive waste disposal involving the separation of aleatory and epistemic uncertainty

In 2001, the National Nuclear Security Administration (NNSA) of the U.S. Department of Energy (DOE) in conjunction with the national security laboratories (i.e., Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and Sandia National Laboratories) initiated development of a process designated quantification of margins and uncertainties (QMU) for the use of risk assessment methodologies in the certification of the reliability and safety of the nation's nuclear weapons stockpile. A previous presentation, “Quantification of Margins and Uncertainties: Conceptual and Computational Basis,” describes the basic ideas that underlie QMU and illustrates these ideas with two notional examples. The basic ideas and challenges that underlie NNSA's mandate for QMU are present, and have been successfully addressed, in a number of past analyses for complex systems. To provide perspective on the implementation of a requirement for QMU in the analysis of a complex system, three past analyses are presented as examples: (i) the probabilistic risk assessment carried out for the Surry Nuclear Power Station as part of the U.S. Nuclear Regulatory Commission's (NRC's) reassessment of the risk from commercial nuclear power in the United States (i.e., the NUREG-1150 study), (ii) the performance assessment for the Waste Isolation Pilot Plant carried out by the DOE in support of a successful compliance certification application to the U.S. Environmental Agency, and (iii) the performance assessment for the proposed high-level radioactive waste repository at Yucca Mountain, Nevada, carried out by the DOE in support of a license application to the NRC. Each of the preceding analyses involved a detailed treatment of uncertainty and produced results used to establish compliance with specific numerical requirements on the performance of the system under study. As a result, these studies illustrate the determination of both margins and the uncertainty in margins in real analyses.

Capturing the environment, a metafrontier approach to the drinking water sector

Environmental factors add complexity to the comparison between specific activities or entire entities. Decision making units with an inferior performance are tempted to invoke that their organization is "different" from the others in the data set. By reinterpreting and extending the metafrontier literature, we propose an all-embracing concept to fully capture the operational environment. We suggest the "Group Specific Technical Efficiency" as a new measure to assess the overall efficiency of a utility while allowing for environmental differences. A real-world example of drinking water utilities from five different countries illustrates the concept.
