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.

The Impurity Processing Loop (IPL) of the JET Active Gas Handling System is designed to recover tritium from impurities such as tritiated water and hydrocarbons present in the JET plasma exhaust. All impurities are fully oxidised in a catalytic recombiner, the tritiated water frozen in a cold trap and subsequently decomposed on hot uranium powder. Hydrogen isotopes set free in this reaction are scavenged from the helium carrier gas in a cold uranium bed. The modular design of the IPL permits implementation of advanced processing schemes (eg avoiding solid UO2 waste) in the future without major hardware modifications.
