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 technical feasibility of partitioning concentrated nitric acid intermediate-level waste (ILWC) solutions from the Purex process into a small volume of high-level waste and a large volume of low-level waste using sorption methods is demonstrated for 1-ℓ batches. Cesium-134 and 137Cs are selectively separated with a decontamination factor (DF) greater than 1 × 105 in a newly developed “suspended-bed” column filled with the microporous inorganic exchanger ammonium molybdophosphate. The 125Sb and the actinides and lanthanides with a 3+ valence state are retained with DFs between 40 and 1000 on metal oxides of antimony and manganese and on an extraction column containing n-octyl(phenyl) N,N-diisobutyl carbamoyl methyl phosphine oxide, respectively. Ruthenium-106 and 60Co are removed in a column loaded with dimethyl glyoxime and have DFs greater than 20. The amount of secondary wastes arising from absorber materials is calculated to be 300 kg for a 350 t/yr reprocessing plant with an ILWC volume of ∼0.5 m3/t of heavy metal.
