| 摘要： | The revised 10 CFR Part 20, 'Standards for Protection Against Radiation,' would have substantial impacts on both U.S. Nuclear Regulatory Commission (NRC) and Agreement State licensees. It is estimated that the revision will cost licensees over $170 million (present value); more than half of these costs are related to the new requirement to sum external and internal doses to demonstrate compliance with the annual whole-body effective dose equivalent limit of 5 rem. Fuel fabrication and processing facilities will incur significant costs to reduce levels of airborne uranium to below the applicable derived air concentrations (DACs). The revision would also have substantial benefits, most notably by reducing doses to both workers and the unborn. Of the $44 million (present value) in benefits identified in this analysis, over 80% are related to dose reductions. There were large uncertainties in these estimates, however, and the actual value of the benefit from the reduced doses could be much lower. Although the quantified benefits from the revision do not appear to outweigh the costs, many benefits identified in this analysis were not quantified and their consideration could favor revising 10 CFR Part 20 as planned. |
