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.

Oxidation studies have been carried out on 11.5 to 12.0 g/cm3 density uranium monocarbide microspheres and on mixed 11.96 to 12.04 g/cm3 density uranium-plutonium carbide pellets under various oxygen partial pressures in the 550 to 745 K temperature range. Oxidation of UC and (U,Pu)C produced a U3O8 [oxygen-to-metal ratio (O/M) = 2.66] and (U,Pu)O2 (O/M = 2.15), respectively, with a carbon content of <600 ppm. The surface area of the resultant oxides as determined by the Brunauer-Emmett-Teller method are 1 to 2 and 4 to 5 m2/g, respectively. The oxidized products were suitable for wet and dry recycle.
