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.

Detailed three-dimensional neutronics calculations have been performed for the U.S. design of the ITER magnet shield. The total nuclear heating in the TF coils is 35 kW in the technology phase and 42 kW in the physics phase. Using 5 cm thick W back shield layers behind the vacuum vessel in locations with limited shielding space results in acceptable local magnet damage levels. The parts of the TF coils adjacent to the divertor vacuum pumping ducts are well protected against streaming radiation.
