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.

Based on an examination of thermal and fast reactor fission yield data, specific fission products are recommended as burnup monitors for total fissions in various reactor fuel types and for fractional fissions in 235U-239Pu and 233U-235U reactor fuels. Emphasis is placed on long-lived and stable fission products determined by mass spectrometry. The types of monitors include a single fission product for total fissions and the ratio of two fission product isotopes of the same element both for total fissions and fractional fissions.
