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.

Previous experimental work led to the development of a kinetic model that can be used to quantify iodine sorption behavior on a stainless steel surface. The kinetic model, based on the mechanism proposed in earlier work, consists of four chemical reactions. The model has reproduced the time-dependent adsorbed iodine concentration data on the coupons observed under various atmospheric conditions and different cycles of loading and purging. The iodine adsorption kinetics were then incorporated into a mass transport equation to simulate iodine sorption behavior from a flowing air stream through a length of stainless steel tubing. Discussed are the model, the simulation results, and their implications regarding the calibration of iodine transmission through long stainless steel sampling lines used for radiological monitoring of airborne iodine in a reactor containment building following an accident.
