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.

Solid-state track recorders (SSTR) of muscovite mica have provided absolute fission rates and fission ratios for 235U and 238U in ZPR-6, Assembly 5. The results agree well with diffusion theory and satisfactorily with radiochemical fission rate measurements. However, comparisons with fission chamber measurements reveal some differences, which can be attributed to the perturbing influence of the fission counter itself. Due to the high sensitivity of the SSTR method, measurements were readily extended into the blanket region of the assembly. Simplicity, reliability, and the wide sensitivity range make SSTR measurements an unusually powerful method for fission rate studies in low-power reactors.
