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.

The magnetic configuration of a field-reversed configuration (FRC) has a center closed region and open field region. Because of this geometrical property, an FRC can be translated from a formation theta-pinch region into a confinement region while it keeps the closed magnetic field. In this work, the "equivalent" neutral beam injection (NBI) in the translation process has been proposed as a heating and particle injection method for an FRC. Translating an FRC plasma through neutral gas background is equivalent to an end-on NBI into the FRC. For the neutral particle density of 1 × 1020m-3, translation velocity of 100km/s and translation length of 1m, the number of particles ~3 × 1018 and the kinetic energy of ~40J are supplied due to the equivalent NBI.
