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.

An analytical model describing pressure fluctuation of turbulent flow in liquid-metal fast breeder reactor (LMFBR) fuel assemblies has been proposed, and the oscillation amplitude of a fuel pin thus caused has been calculated. In the treatment, the statistical model for pressure fluctuation in stable turbulent flow was assumed, and the fluctuation was estimated from pressure loss of flow and velocity gradient. The vibration amplitude was calculated by solving a Langevin equation. According to the comparison of the calculated results with experimental data, this model realistically describes the fuel pin vibration in LMFBR fuel assemblies.
