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.

An intense neutron source capable of generating the characteristic flux of a fusion reactor (1-4 MW/m2) is an essential element for adequate reactor materials assessment. Based on recent experimental results involving the magneto-kinetic compression of the Field Reversed Configuration (FRC), it is believed that such a fusion based neutron source can be rapidly developed at low cost. The ability to provide a fusion plasma with the necessary radiation intensity is afforded by the considerable increase in fusion neutron yield that occurs concurrently with the large reduction in reacting plasma volume from the straightforward magnetic flux compression of an FRC plasmoid. Pulsed formation and flux compression of FRCs in a prototype device operating at 4 Hz would yield a neutron power fluence at the wall of 1 MW/m2 from a fusion plasma volume of a half liter. This is roughly a factor 106 smaller than a reactor-scale fusion plasma such as ITER, thereby dramatically reducing the cost and time for the evaluation of materials for fusion application. The required magnetic compression field and energy per pulse is less than 16 T and 100 kJ respectively.
