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.

St 198 alloy is attractive for glovebox clean-up systems operating with nitrogen cover gases, offering good tolerance to impurities which may permeate into the box from the environment and stable sorption speeds for alloy loadings as high as 360 mCi/g. At this loading the tritium concentration in the stream leaving the scavenger bed will be of the order of 400 µCi/m3. The alloy operating conditions can be adjusted to increase the quantity of tritium stored in the alloy or to reduce the tritium concentration in the effluent. Methane can not be removed from a nitrogen stream with St 198. A glovebox clean-up system based on the use of this alloy is under evaluation.
