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.

For thick liquid wall concepts, it is important to understand the different mechanisms affecting the chamber dynamics and the state of the chamber prior to each shot as compared with requirements from the driver and target. These include ablation mechanisms, vapor transport and control, and possible aerosol formation, as well as protective jet behavior. This paper focuses on these research topics and aims at identifying the major issues, assessing the latest results, reviewing the capabilities of existing modeling and experimental facilities with respect to addressing remaining issues, and helping guide future analysis and research and development efforts.
