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 neutron spectrometry system is proposed to provide information about the ion plasma temperature profiles in the International Thermonuclear Experimental Reactor (ITER) cross section. The system consists of two fanlike arrays of spectrometers and collimators positioned horizontally (20 channels) and vertically to the machine (10 channels). The devices are intended for use in both the deuterium-deuterium (D-D) (physical) and deuterium-tritium (technology) phases of ITER operation. For the D-D phase of operation, a system using NE-213 liquid scintillators and a 3He ionization chamber is proposed. A new high-performance neutron spectrometer based on recoil-proton energy measurements by means of a semiconductor detector and neutron spectrum unfolding is proposed for the technology phase.
