Russia withdraws from 25-year-old weapons-grade plutonium agreement
Russia’s lower house of Parliament, the State Duma, approved a measure to withdraw from a 25-year-old agreement with the United States to cut back on the leftover plutonium from Cold War–era nuclear weapons.

A new interpretation of the in situ TRIO experiment on tritium release from γ-LiAlO2 ceramic particles is presented. It is suggested that, due to a very small ceramic particle radius (R = 0.1 µm), the release-controlling phenomenon is desorption of tritium-containing molecules from the particle surface rather than tritium diffusivity in the particle. This hypothesis eliminates the large discrepancy with previous tritium diffusivity experiments with large particles, where the time-controlling phenomenon is clearly diffusivity.
