Significant progress has been achieved on radionuclide transport in fractured rocks due to
worldwide urgent needs for geological disposal of high-level radioactive waste (HLW) …

During the past half-century, the nuclear fuel cycle has generated approximately 1400 metric
tons of plutonium and substantial quantities of the “minor” actinides, such as Np, Am, and …

The radiation performance of a variety of complex oxides is predicted on the basis of a
material's propensity to accommodate lattice point defects. The calculations indicate that a …

This review provides a comprehensive evaluation of the state-of-knowledge of radiation
effects in crystalline ceramics that may be used for the immobilization of high-level nuclear …

Stepwise degassing diffusion experiments on 39 different apatite samples using radiogenic
4He and proton-induced 3He reveal a range in closure temperature (Tc) from∼ 50 to 115° …

Experimental Ti K-edge x-ray-absorption near-edge structure (XANES) spectra for a variety
of Ti (IV)-bearing crystalline oxide model compounds are compared with those calculated …

This review summarizes the recent developments regarding the use of uranium as nuclear
fuel, including recycling and health aspects, elucidated from a chemical point of view, ie …

The disposition of actinides, most recently 239Pu from dismantled nuclear weapons,
requires effective containment of waste generated by the nuclear fuel cycle. Because …

This paper is a comprehensive review of the state-of-knowledge in the field of radiation
effects in glasses that are to be used for the immobilization of high-level nuclear waste and …

As the emerging versatile waste forms for immobilizing actinide-rich radioactive wastes,
glass-ceramic composite materials based on some durable ceramic phases are being …
