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.

A magnetic divertor is introduced to the HIEI tandem mirror to enhance the MHD stability in axisymmetric magnetic configuration. It is confirmed that the MHD flute modes can be stabilized by the divertor located at the midplane or off-midplane in the central cell. As the position of the magnetic nulls of the divertor is located at smaller radii, the plasma can be sustained with less fueling rates. The magnetic divertor provides a method to greatly enhance the stability of the flute modes for plasmas weakly stabilized by the RF ponderomotive force.
