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 DT fusion neutron yield is calculated as a function of plasma current I for a variety of cases, assuming that the plasma temperature scales as To = Tr(I/Ir)y(ar/a)x where subscripts r denote reference values, and x and y are scaling parameters. The first-wall minor radius a is limited by the tolerable heat flux q. If β = 15 %, R = 4 m, I = 10 MA, and q = 3 MW/m2, then a = 0.43 m, and the 14 MeV neutron current at the first wall is about 1018 neutrons/m2s. a Work begun at Phillips Research Center.
