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.

The total neutron cross sections of Zircaloy-2, zirconium-90, and carbon have been measured in the energy range 0.4 to 2.4 MeV, using the Bettis 3-MeV Van de Graaff pulsed-beam time-of-flight system in conjunction with a NE213 pulse-shape discrimination transmission detector for gamma-ray discrimination. Results obtained far Zircaloy-2 are significantly lower than prior evaluated data near 1 MeV. In addition, the zirconium-90 results average 6 to 7% below the Zircaloy-2 results.
