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.

Extensive recycle of nitric acid and water in a nuclear fuel reprocessing plant can result in the buildup of deleterious trace impurities; identified materials of serious concern include fluoride, chloride, and organic materials. Methods for removal of these deleterious materials must be developed to allow increased aqueous recycle. Fluoride at 10 to 100 µg/ml can be removed from 10 M HNO3 using a silica gel column. Chloride can be removed from 10 M HNO3 by sparging with ozonized air, a method that is rapid even at room temperature. Carbonaceous material can be removed by pressurized aqueous combustion and by ozonation and the latter can be greatly accelerated by the presence of Ag+ ions.
