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 studied the feasibility of an efficient current-drive scheme using radio-frequency (rf) waves on the alpha particles produced in a reactor tokamak. Traveling fast waves, generated as waveguide modes in the plasma, are found to be particularly suitable for implementing such a scheme. The scheme involves using rf power to prohibit the alpha particles from slowing down isotropically and in pushing the alpha particles in a preferential direction and thus form an alpha-particle beam, which, through interaction with electrons, sustains a current. Numerical estimates for the current-drive efficiency were obtained using plasma parameters characteristic of the Argonne National Laboratory design of a reactor tokamak.
