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 four neutron groups populating the ground state and the lower three excited states of 28Si were studied with a stilbene neutron spectrometer. Total neutron cross sections were obtained from measurements at detection angles of 0, 45, 90, and 135 deg. A large number of resonances were seen, indicating many levels in 29Si. By using the reciprocity theorem, the cross sections for 28Si(n,α0)25Mg reaction were obtained and compared with those given in the literature.
