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 installed defueling water cleanup system filters experienced severely reduced operating life. This was caused by blinding of the filter media due to colloidal material located within the Three Mile Island Unit 2 (TMI-2) reactor vessel. Through laboratory testing, a combination of coagulant and filter aid placed on the filter media was found to extend operating time tenfold. A system of pumps, mixers, tank, and control was developed to apply the coagulant and filter aid to the filters located in the TMI-2 damaged containment.
