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 transmutation concept of minor actinide (MA)–bearing nuclear fuel plays an important role in managing highly radioactive waste. A facile route combining the sol-gel process and microfluidic technology was presented to fabricate Ce/Eu oxide microspheres as a surrogate for plutonium-based MA-bearing nuclear fuel. Uniform Ce/Eu oxide microspheres with a varied Eu content (7.90%, 13.00%, and 17.56%) were successfully fabricated using the co-sol-gel method. The prepared microspheres had a narrow size distribution (coefficient of variance < 2%) and excellent sphericity (dmax/dmin < 1.09). The Ce and Eu elements were shown to have a relatively homogeneous distribution in the microspheres through energy dispersive X-ray spectroscopy mapping images. Thermal behavior analysis, microstructure observation, and crystalline structure analysis were conducted systematically. The X-ray diffraction patterns showed one cubic lattice structure for all of the samples.
