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.

Measurements of impurities and tritium releasing characteristics of Lithium Aluminate and Zirconate, prepared by ENEA in the frame of the European Program on Fusion Technology, have been performed, respectively, by neutron activation analysis (NAA) and “out of pile” annealing. The resulting tritium removing rate from the ceramics was interpreted in terms of surface desorption kinetics. With reference purge gas (He + 0.1% H2), the predominant form of tritium, released by lithium aluminate is HT/T2, HTO/T2O by lithium zirconate. The latter was found to have a better performance in tritium release than aluminate. The presence of moisture was found to catalyse the tritium release at lower temperatures.
