NUCLEAR REGULATORY COMMISSION
[NRC-2012-0108]
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.

SUPPLEMENTARY INFORMATION:
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
[[Page 9927]]
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
SNF.
