Abstract
Rails are subjected to repeated stresses due to wheel-rail contact during train service. Rails under stress conditions undergo microstructural changes, and these cause degradations of the structural integrity and lifetime of rails. In this study, three different rails (newly-manufactured rail, newly-manufactured head-hardened rail, and worn (used) rail) were compared to.....

Abstract
The objective of this study was to obtain basic data for trapping gaseous technetium (Tc) oxide generated from the voloxidation process in spent nuclear fuel pyroprocessing. Rhenium (Re) and Ca(OH)
2
were used as surrogates for the technetium and a trapping material, respectively. The trapping characteristics of rhenium oxide were investigated.....
