Fires extinguished at Chernobyl following drone strike
Ukraine’s State Emergency Service has finally gained full control over a blaze that started February 14 after a drone struck the protective dome over the destroyed reactor from the 1986 Chernobyl nuclear plant accident.

The effects of thermonuclear alpha particles on the stability of global-type shear Alfvén waves in toroidal geometry in an ignition tokamak experiment are described. The presence of finite toroidicity can lead to stabilization of the global shear Alfvén eigenmode. However, toroidicity induces a new global shear Alfvén eigenmode that can be strongly destabilized via transit resonance with alpha particles. In the proposed International Thermonuclear Experimental Reactor (ITER), due to its large size and low density, this latter mode is found to be benign.
