説明
In order to calculate criticality parameters of nuclear fuel solution systems, number densities of nuclides relating to the medium such as water or organic solvent are needed and generally calculated from density equations.<BR>Densities of uranyl nitrate-nitric acid and uranyl nitrate-gadolinium nitrate-nitric acid solutions were precisely measured, and two empirical density equations for the solutions were derived as functions of concentrations of solutes, temperature and their products from regression analysis of a number of experimental data.<BR>The density equation for the solution of UO2(NO3)2-HNO3 was compared with published equations and discussed from the viewpoint of the atomic number density of hydrogen.<BR>Density equations for the solution of UO2(NO3)2-Gd(NO3)3-HNO3 have not been reported so far and the effect of gadolinium on the hydrogen atomic number density in the uranium solution has been neglected. The present equation gives accurate number density in the relevant medium.
