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 review of spatial reactor control methods that have employed optimization techniques is presented. Automatic spatial control systems are briefly outlined, the formulation of the spatial control problem as an optimal control problem is discussed, and solution methods based on distributed parameter optimal control, variational calculus, dynamic programming, mathematical programming, the maximum principle, linear-quadratic control theory, and heuristic control techniques are reviewed.
