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.

A prototype expert system is developed to provide information to emergency planners on the time, rate, and magnitude of release of important radioactive isotopes given a loss of containment integrity. Basic to the method is the anticipated availability of instruments to measure concentration of significant individual radioisotopes in containment ∼1/min. The escape of radioisotopes is assumed to be proportional to that of noncondensable gases, which are monitored and/or predicted in part. If such a system can be executed practically, it would provide actual release information not available with monitoring systems currently deployed.
