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.

Possibilities for improving the performance of conventional 60 cm thick uniform composition Fe-H2O shields backed by a B4C layer are investigated. The maximum heating rate in the superconducting coils due to (1) Optimally distributing the Fe and H2O across the shield; (2) Optimally distributing the Fe, H2O and B4C; (3) Using TiH2 as the primary hydrogeneous material; (4) Using tungsten instead of iron; and (5) Using a tungsten-copper composite material instead of tungsten, is found to be, respectively, 1.6, 3.6, 6, 32 and 56 times lower than in the reference shield. The development and use of tungsten-, and TiH2-based composite materials for improving the performance and/or economical attractiveness of radiation shields is proposed.
