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.

Borosilicate glasses containing actual high-level Savannah River Plant waste were leached in static, distilled water. Leach rates based on 90Sr, 137Cs, and plutonium analyses were similar: 10−5 to 10−6 g of glass/(cm2·day) initially, 10−7 to 10−8 g/(cm2·day) after two weeks, and 10−8 to 10−9 g/(cm2·day) after 100 days. The leach rates were not directly correlated with waste composition, but were qualitatively related to the tendency of the glass to devitrify that could be caused by certain combinations of waste components. According to a proposed model, leach rates were diffusion-controlled during the entire 100-day test.
