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.

The thermal-hydraulic behavior of rotating bed reactors is analyzed using the drift-flux model to predict fuel bed expansion. A new correlation for onset of fluidization is developed for this purpose. Parametric effects are discussed and first priority research areas are delineated. Reactor design curves are developed showing small cores between 25- and 50-cm radius should be capable of generating power up to 5000 MW. With exhaust temperatures approaching 3000 K using hydrogen as a propellant, these devices seem especially suited for use in space-tug concepts.
