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 incorporation of actinide and actinide surrogates in borosilicate matrix was studied with uranium, cerium and neodymium. This study was carried out on matrix glasses doped respectively by 10 and 30wt% UO? while CeO?, Nd?O? was used to chemically model the actinides in the matrix. The structure was studied by Neutron diffraction combined with Reverse Monte Carlo simulations. For all studied glasses, it was found that the basic network structure consists of tetrahedral SiO? units and trigonal BO? and tetrahedral BO? units, forming mixed [?]Si-O-[3], [4]B bond-linkages. The BO?/BO? ratio was also proved by NMR spectroscopy. From the first nearest neighbour distances of U-O, Ce-O, Nd-O atomic pairs and from the second nearest neighbor atomic pair correlations we found that uranium, cerium, neodymium ions are located in the borosilicate network.
