ANS and the U.K.’s NI announce reciprocal membership agreement
With President Trump on a state visit to the U.K., in part to sign a landmark new agreement on U.S.-U.K. nuclear collaboration, a flurry of transatlantic partnerships and deals bridging the countries’ nuclear sectors have been announced.
The American Nuclear Society is taking an active role in this bridge-building by forming a reciprocal membership agreement with the U.K.’s Nuclear Institute.

Based on a new theory for redistribution of fast ions during sawtooth crashes, numerical simulations are executed of sawtooth oscillations in the 2.5-MeV neutron emission from neutral beam injection-heated Joint European Torus (JET) plasmas. The analysis includes all sources of 2.5-MeV neutrons: thermal, beam-plasma, and beam-beam deuterium-deuterium reactions. Two models of sawteeth are used in the calculations—both based on magnetic field line reconnection. A detailed comparison with experimental results from JET shows that the theory for sawtooth-induced fast ion redistribution is consistent with the observed changes of the neutron emission.
