Pressure drop tests of single-phase and two-phase flows through a packed bed with micrometer size diameter particles under laminar upward flow conditions were carried out to develop the new pressure drop model for two-phase flow through a packed bed.

The structural model of 66.7PbO-33.3B2O3 glass was constructed using a reverse Monte Carlo (RMC) method, in which bond valence sum (BVS) was added as a constraint condition to suppress formation of unrealistic local structures. Based on the crystal s

To perform a safety assessment for the geological disposal of radioactive waste, it is important to understand the response characteristics of the disposal system. In this study, approximate analytical solutions for steady-state nuclide releases from

This paper describes the validity of two assumptions usually accounted for performance analyses of engineered barriers; nuclide release starts at 1, 000 yr after backfilling of packages, and the chemical environment around the package is kept under a
