加拿大化学作业代写:钚和铀分离

再处理是指以化学方法将钚和铀从乏燃料中分离出来以供再使用的过程,法国就是这样做的。再处理可更全面地利用和挖掘核燃料的能源潜力,并使废物管理更容易,减少废物可能产生的体积和长期危害。然而,分离出来的钚如果落入坏人之手,可能会造成潜在的核威胁,因此需要非常谨慎的安全措施。在多年的停滞之后,二十一世纪的几项要求结合起来,使世界认真考虑了对核能的需要。电力和电力需求的增长在发展中国家,化石燃料的大幅侵蚀全球资源,持续的全球地缘政治动荡,石油和天然气的价格飞涨,严重限制碳排放的需要迫使国家转向核燃料释放他们的能量的担忧。目前的需要是在这一全球使命中进行思考和合作。正如保罗·洛伦西尼所说。最关键的一步是在能源规划者和政策制定者之间建立共识,将“可持续性”作为政策目标,应包括核能。将核能重新纳入能源规划意味着消除意识形态偏见。它意味着思想的开放,以解决人类对现代化的渴望和全球对可持续性的需要之间的紧张关系

加拿大化学作业代写:钚和铀分离

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.After years of stagnation, the several demands of the twenty first century have combined to make the world seriously think of the need for nuclear power. The increase in demand for power and electricity in the developing world, the sharply eroding global resources of fossil fuels, the continuing global geopolitical instability, the skyrocketing prices of oil and gas, and the need to severely restrict carbon emissions are forcing nations to turn towards nuclear fuel for release from their energy worries.The need of the moment is to think and to cooperate in this global mission. As Paul Lorenzini states.The most critical step is to build a consensus among energy planners and policymakers that “sustainability” as a policy goal should include nuclear power. Bringing nuclear power back into the mix for energy planning means shedding ideological biases. It means openness of thinking to resolve the tension between the human desire for modernization and the global need for sustainability
