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.

Tritiated process water is monitored by detecting the D2O component via the 2D(γ,n)1H reaction. A probe containing a 1- to 7-mCi 24Na (15-h) gamma source and six 3He neutron detectors produces and monitors the 2D(γ, n)1H reaction. A variety of probe configurations were examined for D2O detection sensitivity. The corresponding detection limits range from 6 to 280 µl for D2O droplets and 1 to 13 µl/cm for D2O streams, when 10-min neutron counting with a 1-mCi gamma source is used. Results from two field applications illustrate the utility of the monitor.
