Deep Space: The new frontier of radiation controls
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

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.
