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.

In experiments with a microwave heated magnetic cusp, we have observed the formation and collapse of a strongly-magnetized, steady- state plasma. The formation and behavior of the plasma structure were examined in a variety of conditions. Holding microwave power constant and varying magnetic field strength, the plasma structure volume was observed to shrink, and the hole eventually collapsed as field strength was increased. Holding magnetic field strength constant and varying microwave power, the plasma structure's volume decreased as power was increased. However, we did not have sufficient microwave power to cause the hole structure to collapse. The magnetic confinement and the stability of the plasma in the cusp were also observed.
