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.

Expressions are derived for the output, and time derivative of the output, of the simple diode pump circuit corresponding to an input pulse rate which is increasing exponentially with time. Solutions are obtained in numerical form for a series of values of the diode pump parameters. By a linear superposition of the outputs it is possible to predict the transient behavior of the multiple diode pump type of logarithmic rate meter and of the period signals derived from the output. The fluctuations or “noise” in the period meter output signal for random input pulses is also calculated for this type of rate meter. A comparison based on transient response and noise behavior shows the multiple diode pump circuit to be potentially superior to the simpler logarithmic diode type of rate meter.
