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.

This will probably be the best set of lightning talks, ever. We will adhere strictly to the schedule. Everyone's mics will sound great. Speakers will start with their conclusions so you may have everything you need in the first minute! The chat will be overflowing with questions and answers. You may think this sounds stressful, but we will not panic and get overwhelmed. We'll enjoy learning about so many colleagues activities in such a short amount of time (the efficiency!) and revel in the technical diversity that is computational tools for reactor physics applications.
