NRC nominee Nieh commits to independent safety mission
During a Senate Environment and Public Works Committee hearing today, Ho Nieh, President Donald Trump’s nominee to serve as a commissioner at the Nuclear Regulatory Commission, was urged to maintain the agency’s independence regardless of political pressure from the Trump administration.

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.
