In connection with the high rates of development of nuclear power engineering a problem of optimizing the process of nuclear fuel production and improving its performances remains relevant. Currently, the main way to obtain UO2 fuel pellets is the method of Cold Pressing and Sintering (CPS). The main disadvantages of this method are large sintering duration (up to several hours) and high...

In recent years, much attention has been drawn to the photo- and radiation-induced synthesis of various materials. In presented work, radiation-induced synthesis of nanocrystalline uranium and/or thorium oxides is investigated. Uranium(IV) oxide is widely used as a fuel in various types of nuclear reactors [T. Abe and K. Asakura: 2.15 Uranium Oxide and MOX Production. In: Comprehensive Nuclear...

At this time development of any complex chemical plant (including spent nuclear fuel reprocessing plant) should be accompanied with plant governing model development. Creation of such a model is especially significant while developing innovative plants, many technological processes of which have no industrial-scale solutions and number of processes require R&D work in corresponding...

Ba(NO3)2 precipitation is one of the limiting factors in HLW evaporation during NPP spent fuel reprocessing. The model was proposed in our previous work [1] for approximation of the Ba(NO3)2 and Sr(NO3)2 solubility in HNO3 solutions using the law of mass action. As a result the two linear areas where identified according to slope of the solubility on total nitrate ion concentra-tion in...
