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 high energy low current CW Hall accelerator with preionization discharge (HAPID) has been developed, and has shown excellent performance characteristics. The purpose of developing the HAPID is to produce beam plasma having energy spectrum similar to the exhaust plasma from the future tandem mirror reactors. So far we have achieved more than 1 A (drain current) hydrogen beam plasma of up to 20 keV for 10 seconds with more than 40 % power efficiencies and beam half-angles of less than 6 degrees. Also good reproducibility and stable discharge initiation were obtained without exhausting filaments when the preionization in the anode region was on. Extracted beam showed three peaks in energy distribution.
