In April 1989 the Soviet Navy’s nuclear submarine Komsomolets caught fire while cruising 335 m beneath the surface of the ...

Under the draft proposal, the principle that exposure should be “as low as reasonably achievable” will be replaced with hard limits and special exceptions.

In the quest for ultra-precise timekeeping, scientists have turned to nuclear clocks. Unlike optical atomic clocks—which rely on electronic transitions—nuclear clocks utilize the energy transitions in ...

Used nuclear fuel is one of the most persistent challenges facing nuclear energy. Long after a reactor stops using it, the material remains intensely radioactive, requiring cumbersome and expensive ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...

A Washington-based company has successfully validated its borehole technology for safe disposal of high-level ...

Using lasers with precisely tuned frequency, λ, physicists control rotational states of radium monofluoride molecules and excite specific rotational levels, characterized by the quantum number, J.

Last May, Trump signed four executive orders aimed at reviving what he called an industry “atrophied” by regulation. The US ...

In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei. Recognizing these numbers helps scientists better understand the structure ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study, led by the ...
