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.

Cryosorption pump is very convenient means for hydrogen isotope transportation, since a cryopump combines a vacuum pump, compressor and temporary storage reservoir of hydrogen isotopes. We have studied zeolites as the cryosorbent for hydrogen isotope fore-vacuum pumping. The prototype of the cryosorption pump was designed, made and tested. It is shown that synthetic chabazite CaET-4B has the highest adsorption capacity in relation to hydrogen isotopes in the low pressure region. The equation of the adsorption isotherms was obtained. The results of the testing and operation of the cryopump for hydrogen isotopes transport are described. The pump is simple, reliable and allows to reduce the losses of deuterium and exclude tritium release to atmosphere and the formation of tritium wastes.
