摘要

UO2粉末的特性对UO2基燃料和铀基金属及合金燃料的生产都至关重要。作为UO2基燃料或作为金属铀基燃料，UO2所需的质量参数是不同的。采用两种不同的方法制备UO2粉体:(1)由重铀酸铵热分解产物还原，(2)由重铀酸铵直接还原。研究了两种方法制备的UO2粉末的氧铀比(O/U)、比表面积(SSA)和晶体结构。

Comparative study on the properties of UO2 produced by direct reduction of ADU and reduction of calcined product of ADU

The characteristics of UO2 powder are crucial for production of both UO2 based fuel and uranium based metallic and alloy fuel. Depending upon the usage as UO2 based fuel or as metallic uranium based fuel, the desired quality parameters of UO2 are different. The UO2 powder was produced by two different methods: (1) by the reduction of the thermal decomposed product of ammonium diuranate and (2) by the direct reduction of ammonium diuranate. Oxygen to uranium ratio (O/U), specific surface area (SSA) and crystal structure of UO2 powder produced by these two methods were studied.

期刊介绍： Today, nuclear reactors generate nearly one quarter of the electricity in nations representing two thirds of humanity, and other nuclear applications are integral to many aspects of the world economy. Nuclear fission remains an important option for meeting energy requirements and maintaining a balanced worldwide energy policy; with major countries expanding nuclear energy"s role and new countries poised to introduce it, the key issue is not whether the use of nuclear technology will grow worldwide, even if public opinion concerning safety, the economics of nuclear power, and waste disposal issues adversely affect the general acceptance of nuclear power, but whether it will grow fast enough to make a decisive contribution to the global imperative of sustainable development.
