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.

Systems considerations influencing the design of vertical, centrifugal, and free surface pumps for liquid-metal fast breeder reactors are evaluated. Systems were analyzed to guide in selections for pumps with flow ranges of 10 000 to 200 000 gal/min and head ranges from 100 to 450 ft for both the sea-of-sodium and piped reactor arrangements. The system analyses defined the parametric relationships between the pump, the coolant system, and the overall plant requirements. The plant arrangement, piped or sea-of-sodium, affects the net positive suction head available, choice of pump location, the severity of the thermal transients, system pressure levels, and ease of operation and maintenance.
