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.

The ion to electron temperature ratio (Ti/Te) is a crucial parameter that affects fusion plasma performance, especially for higher temperature advanced fuel operation. An important factor in the determination of Ti/Te is the equilibration of energy between ions and electrons. The effect of changes on equilibration rates due to the presence of a magnetic field are considered here. It is found that rates are increased for low beta (∼10%) high temperatures (∼75 keV) Cat-D plasmas, causing a decrease in Ti/Te and a corresponding increase in nτE tor ignition of ∼75%. This effect is less pronounced for high-beta plasmas. Scaling of the changes in equilibration power with macroscopic quantities are presented.
