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.

Experimental and theoretical studies have been performed to characterize the behavior of airborne particulates (aerosols) expected to be produced by hypothetical core disruptive accidents (HCDAs) in liquid-metal fast breeder reactors (LMFBRs). These aerosol studies include work on aerosol transport in a 20-m-high, 850-m3 closed vessel at moderate concentrations; aerosol transport in a small vessel under conditions of high concentration (∼1 kg/m3), high turbulence, and high temperature (∼2000°C); and aerosol transport through various leak paths. These studies have shown that little, if any, airborne debris from LMFBR HCDAs would reach the atmosphere exterior to an intact reactor containment building.
