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 use of the compressional hydromagnetic (fast wave) mode is examined with respect to heating a minority helium-3 species in a fully catalyzed deuterium tokamak. In this paper we develop a rapid solution to analyze the two dimensional, steady state Fokker-Planck equation, with quasi-linear ICRF heating terms. This finite element solution for the minority helium-3 distribution function develops a high, anisotropic in the perpendicular velocity direction, energy tail as a result of ICRH. The rapidity of this method of solution makes it possible to conduct parametric studies which are not possible with other codes.
