澳洲环境学论文代写:核废料的处理

需要考虑的两个主要领域是核废料的处理和乏燃料的再加工。核能的可持续性,使其长期运作的能力,以及将其视为解决全球电力问题的真正长期办法的能力,取决于能否找到一个可接受和可行的办法来解决管理核废料的问题。核废料与其他有毒残留物的分类不同,需要安全保存数千年,而50至70年之间的非放射性毒物的时限要短得多。这一领域需要在两个方面进行工作:进行持续的科学研究,需要大量的政府和机构资金来找到解决储存问题的办法,以及重新审视监管法律,以评估它们是否可以在不损害安全的情况下被重新审视。再处理涉及到钚和铀从乏燃料中化学分离出来重新利用的过程,法国就是这样做的。再处理可以更全面地使用和利用核燃料的能源潜力,使废物管理更容易,减少了废物可能产生的体积和长期危害。然而,分离出来的钚可能会造成潜在的核威胁,如果它找到了错误的途径,并且再次需要非常小心的安全措施。

澳洲环境学论文代写:核废料的处理

The two major areas that demand consideration are the disposal of nuclear waste and the reprocessing of spent fuel. The sustainability of nuclear power, the ability to make it work for long time frames and to think of it as a real long term solution to the global power issue depends upon obtaining an acceptable and workable solution to the problem of managing nuclear waste. Nuclear wastes are classified differently from other toxic residues and need to be kept safely for thousands of years, whereas the timeframe for non radioactive toxics of between 50 to 70 years is far less. Work is needed in this area on two fronts, the carrying out of continuous scientific research, needing significant governmental and institutional funding to find a solution to the storage problem, and a fresh look at regulatory laws to assess whether they can be revisited without compromising safety.Reprocessing relates to the process in which plutonium and uranium are chemically separated from spent fuel for reuse, as is done in France. Reprocessing allows for more complete usage and tapping of the energy potential of nuclear fuel and makes waste management easier, reducing both bulk and long term hazards which could arise from the waste. However, the separated plutonium could create a potential nuclear threat, if it finds its way to the wrong hands, and again will need very careful security.
