Neptunium is a byproduct of plutonium production activities and results from the capture of neutrons by uranium isotopes, usually in a nuclear reactor. Neptunium isotopes can be formed by a variety of …

Neptunium-237 was produced when depleted uranium (containing 238 U) or enriched uranium (containing 235 U) was irradiated in one of the nuclear reactors (Driggers and St. John 1957). …

The chemical properties of neptunium (rhenium-homologous or uranium-like) were elucidated by co-precipitation of carrier-free activities on inactive precipitates.

The present study employs Density Functional Theory (DFT) methodology to assess the thermodynamic feasibility of protonation reactions for the Np(VII) anion complex and the impact on its reduction to …

21 4.93.1 Neptunium isotopes in industry 23 22 237Np (with a half-life of 2.14 × 106 years) is fissionable, meaning that neptunium can be 24 bombarded with neutrons and, as a result, will create …

The isolation of this four-coordinate, neptunium(V) complex reveals a fundamental reaction pathway in transuranic chemistry.

The radioactive element neptunium is one of the principal components of nuclear waste.
