The migration of radionuclides²³⁷Np,²³⁸Pu and²⁴¹Am in a weak loess aquifer: A field column experiment

Abstract

The migration of radionuclidesThe water flow velocity in the experimental column was calculated as 1.15±0.05 cm/d. The activity distribution of

The Influence of Agitation Speed on the Morphology and Size Particle Synthesis of Zr(HPO<sub>4</sub>)<sub>2</sub>·H<sub>2</sub>O from Mexican Sand

“…Early studies were made on the natural apatite whose results suggested some problems due to the dissolution of the materials with pH changes [3]. Due to their abundance in the geosphere, much attention has been paid to the aluminosilicates and clays with a view to finding suitable engineered barriers for radioactive wastes confinement [4,5]. Recently, phosphated derivates containing lanthanum, thorium and uranium have been also studied in order to produce stable materials with sorbent properties [6].…”

Long-Term Chemical Alteration of 238Pu-Doped Borosilicate Glass in a Simulated Geological Environment with Bentonite Buffer

“…Experiments with trace amounts of radionuclides were performed in several underground research facilities (URF) [19][20][21], however, experiments with real vitrified radioactive waste were not yet performed in URF. Up to now, laboratory scale leaching and alteration tests is the only possibility to study complex interactions between the solidified waste, buffer, and host rock in static and dynamic conditions.…”

Design and simulation of networks for midrange wireless power transfer

“…In recent years, WPT has found application in numerous fields at various voltage and power levels [1], [2], [3]. There are different methods used to transfer the power without use of wires based on distance between source and load.…”
