Environmental contamination caused by radionuclides, in particular by uranium and its
decay products is a serious problem worldwide. The development of nuclear science and …

Approximately five percent of all known minerals contain U as an essential structural
constituent (Mandarino 1999). Uranium minerals display a remarkable structural and …

The primary waste form resulting from nuclear energy production is spent nuclear fuel (SNF).
There are a number of different types of fuel, but they are predominantly uranium based …

By 1911, the atomic weight of uranium had been refined to 238.5 (Gmelin, vol. A2, 1980a).
The natural isotope 235 U was discovered in 1935 by mass spectrometry. The artificial …

INTRODUCTION ranium is a widespread groundwater contaminant at many sites where
uranium was processed (Macaskie, 1991; Wolbarst et al., 1999; Wronkiewicz and Buck …

ABSTRACT A facultatively anaerobic, acid-resistant bacterium, designated strain FRCl, was
isolated from a low-pH, nitrate-and U (VI)-contaminated subsurface sediment at site FW-024 …

The influence of U (VI)–CO 3 and Ca–U (VI)–CO 3 complexes on U (VI) adsorption onto red
soil and nanoscale zero-valent iron (NZVI) was investigated using batch adsorption and …

We have made observations of noble metal phase fission-product agglomerates and
gaseous xenon within the fuel-cladding interaction (FCI) zone of a high-burnup UO2 fuel …

This paper reviews not the largest, but at the same time quite an interesting, group of natural
and synthetic uranyl molybdate compounds. Nowadays, nine minerals of U and Mo are …

Spent nuclear fuel, mainly UO2, is chemically unstable under oxidizing conditions. Alteration
occurs by oxidation and hydration and can be rapid and substantial. Uranyl minerals …
