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.

Multiregion critical cores, built on a split-table assembly machine, have been used to investigate reactor compositions typical of epithermal and fast power reactors. The design and operating features of the facility, constructed to study the Th-U233 fuel cycle, are described. Criticality calculations have been in good agreement with experimental values.
