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.

The formation of the spectrum of ions leaving the Z-pinch constriction during its compression is considered in the framework of the thermal mechanism corresponding to collisional regimes at high density. This mechanism refers to the heating of all ions due to compression without consideration of the electromagnetic acceleration of any selected group of ions. It is shown that such conditions can be implemented in relatively high-density regimes in which the product of precompression density and radius is n0a0 ≫ 1024 m–3. Neutron yield is analyzed. Possible parameters of a fusion reactor based on a high-density Z-pinch are estimated and found to be extremely high in terms of today’s technology.
