B. Submitting Comments

    Please include Docket ID NRC-2012-0108 in the subject line of your 
comment submission, in order to ensure that the NRC is able to make 
your comment submission available to the public in this docket.
    The NRC cautions you not to include identifying or contact 
information in comment submissions that you do not want to be publicly 
disclosed. The NRC posts all comment submissions at http://www.regulations.gov as well as entering the comment submissions into 
ADAMS, and the NRC does not edit comment submissions to remove 
identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to 
include identifying or contact information in their comment submissions 
that they do not want to be publicly disclosed. Your request should 
state that the NRC will not edit comment submissions to remove such 
information before making the comment submissions available to the 
public or entering the comment submissions into ADAMS.


    The NRC is responsible for issuing regulations (Title 10 of the 
Code of Federal Regulations (10 CFR) part 71, ``Packaging and 
Transportation of Radioactive Waste,'' dated January 26, 2004) for the 
packaging and transport of spent nuclear fuel (and other large 
quantities of radioactive material) that provide for public health and 
safety during transport. In September 1977, the NRC published NUREG-
0170, ``Final Environmental Statement on the Transportation of 
Radioactive Material by Air and Other Modes,'' which assessed the 
adequacy of those regulations to provide safety assurance. In that 
assessment, the measure of safety was the risk of radiation doses to 
the public under routine and accident transport conditions, and the 
risk was found to be acceptable. Since that time there have been two 
affirmations of this conclusion for spent nuclear fuel (SNF) 
transportation, each using improved tools and information. This report 
presents the results of a fourth investigation into the safety of SNF 
transportation. The risks associated with SNF transportation come from 
the radiation that the spent fuel emits, which is reduced--but not 
eliminated--by the transportation cask's shielding, and from the 
possibility of the release of some quantity of radioactive material 
during a severe accident. This investigation shows that the risk from 
the radiation emitted from the cask is a small fraction of naturally 
occurring background radiation, and that the risk from accidental 
release of radioactive material is several orders of magnitude less. 
Because there have been only minor changes to the radioactive material 
transportation regulations between NUREG-0170 and this risk assessment, 
the calculated dose due to the radiation from the cask under routine 
transport conditions is similar to what was found in earlier studies. 
The improved analysis tools and techniques, improved data availability, 
and a reduction in the number of conservative assumptions has made the 
estimate of accident risk from the release of radioactive material in 
this study approximately five orders of magnitude less than what was 
estimated in NUREG-0170. The results demonstrate that the NRC 
regulations continue to provide adequate protection of public health 
and safety during the transportation of SNF. The staff is seeking any 
information that is germane to these results that the public may wish 
to offer.

    Dated at Rockville, Maryland, this 4th day of May, 2012.

    For the Nuclear Regulatory Commission.
