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.

We have performed preliminary experimental tests for the development of a neutron spectrometer based on activation foils with short half-lives for the European ITER TBMs. Small samples of candidate materials have been irradiated with DT neutrons from the neutron generator of Technical University of Dresden. A dedicated pneumatic sample transport system has been set up for these initial tests and further development of methods for spectral neutron flux measurements in the TBM. The mass of the samples was on the order of 0.6 g. Although the neutron flux in the irradiation position of the samples was three to five orders of magnitude below the expected flux in the TBM at full DT operation of ITER, it was possible with short irradiation time of 60 s and similar gamma-ray measurement times to obtain the induced activity with moderate uncertainty.
