Spent Fuel Transportation Risk Assessment

AGENCY: Nuclear Regulatory Commission.

ACTION: NUREG; issuance.


SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing NUREG-
2125, ``Spent Fuel Transportation Risk Assessment.'' This NUREG 
provides an update of the estimated impacts from transporting spent 
nuclear fuel (SNF) by highway or railway in NRC certified casks under 
both routine and accident conditions.

I. Discussion

    NUREG-2125, ``Spent Fuel Transportation Risk Assessment,'' provides 
an update of the estimated impacts from transporting spent nuclear fuel 
(SNF) by highway or railway in NRC certified casks under both routine 
and accident conditions. The draft NUREG-2125 (ML12125A218) was issued 
on May 14, 2012 with a 60-day public comment period (77 FR 28406). The 
NRC received 4 public comments and the resolution of these comments is

included in the Public Comment Resolution Report (ADAMS Accession No. 
ML13249A337). In addition, the report was reviewed by the NRC Advisory 
Committee on Reactor Safeguards Subcommittee on Radiation Protection 
and Nuclear Materials and by the full Advisory Committee on Reactor 
Safeguards (ACRS). The responses to comments from these two committees 
are included in the ACRS Comment Resolution Report (ADAMS Accession No. 
ML13249A340). The final NUREG incorporates changes to address public 
and ACRS comments.
    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 NUREG shows that the risk from 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 NRC's original transportation risk assessment 
NUREG-0170, (ADAMS Accession No. ML022590355, 1977) and this risk 
assessment, the calculated dose due to the radiation from the cask 
under routine transport conditions is similar to what was found 
earlier. 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 in NUREG-2125 demonstrate that the NRC's regulations in 
Part 71 of Title 10 of the Code of Federal Regulations, ``Packaging and 
Transportation of Radioactive Material'' continue to provide adequate 
protection of public health and safety during the transportation of
