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 electron temperature and a volume-averaged plasma density are experimentally investigated for various argon gas pressure and rf power in permanent-magnets-expanding plasma sources with two different diameters of 6.6 cm and 13.3 cm for the purpose of performance improvement of a electrodeless, magnetically expanding plasma thruster. The results are compared with a global model using particle balance and power balance equations. The theoretical values are in fair agreement with the measured ones. The experimental and modeled results suggest that a ~50 percent increase in the thrust from the electron pressure can be achieved by the enlargement of the source diameter from 6.6 to 13.3 cm.
