Expiration Term for Certificates of Compliance for Transportation Packages Bernie White, Senior Project ManagerTorre Taylor, Senior Project ManagerNMSS/DSFMTWFN Auditorium December 11, 2018 Outline of Presentation

• Background

• Development of basis for expiration term

• Conclusions

• Next Steps

• Contacts*Questions 2

Background

• Report dated August 16, 2017 (ML17228A217)

• Recommendation

-Conduct an analysis, document, and communicate to stakeholders the regulatory and technical bases for the part 71 certificates of compliance term 3

Development of Basis for Expiration Term*Consulted with DOT*Evaluated Risk Studies

• Public meeting with stakeholders

• Discussion with international counterparts at June 2018 Transportation Safety Standards Committee (TRANSSC) meeting

• Considering outcomes from these interactions and evaluation of risk studies 4

Development of Basis for Expiration TermEvaluated four risk studies

• NUREG-0170, "Final Environmental Statement on the Transportation of Radioactive Material by Air and Other Modes"*NUREG/CR-4829 Shipping Container Response to Severe Highway and Railway Accident Conditions"

• NUREG/CR-6672, "Reexamination of Spent Fuel Shipment Risk Estimates

-Main Report"*NUREG-2125, "Spent Fuel Transportation Risk Assessment" 5

Development of Basis for Expiration TermConclusion from reviewing risk studies

• NUREG-0170: The risk from transportation accidents was found to be low. Study evaluated:

-Radiation dose from normal transportation

-Risk from accidents

• Each subsequent study found the risk to be even lower than previously thought 6 Development of Basis for Expiration TermOutreach to stakeholders

• Public meeting

-April 26, 2018

• Summary of comments from the public meeting

-Consistency is important

• DOT, International, and IAEA safety standards-Shorter expiration term not needed for safety

• Safety is not determined by certificate expiration term*Risk associated with fabrication of packages and use 7 Development of Basis for Expiration TermOutreach with international counterparts

• June 2018 TRANSSC meeting

-Informal discussion with international counterparts

• Summary of comments from international counterparts

-Rely on operating experience to evaluate performance of the certificates, i.e., approved designs

-Consistency is important

-Consistent with revision schedule of IAEA Safety Standards-All Member States use the same term forapproved certificates 8

Conclusions

• Safety is associated with the fabrication and use of the package; not with the certificate term

• NRC staff has determined that a 5

-year expiration term is appropriate

-Certificate holders can request a longer expiration term

• Ensures consistency with DOT, international counterparts, and IAEA safety standards revision schedule 9

Next Steps

• Finalize the basis document for the expiration term

• Notice in the Federal Register

-Will not be seeking public comment as the 5

-year term is the current practice and certificate holders can request a longer term

• Revise internal licensing guidance
