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 the separation nozzle process, the enrichment of 235U is achieved by extremely high centrifugal forces in a curved flow of UF6 diluted by a light gas. Remarkable progress has been made in the economy of the process by bringing up the gas pressure and by introducing a nozzle system with double deflection of the jet. While the specific energy consumption is comparable to that of the American diffusion plants, the separation effect per stage is considerably higher than that of the classical technology. Therefore an economical application is possible for smaller and correspondingly cheaper plants. The process finds its first commercial application within the framework of German/Brazilian Cooperation. A so-called First Cascade consisting of 24 separation nozzle stages is under construction in Brazil. The development of components for commercial separation nozzle plants is well under way.
