Expiration Term for Certificates of Compliance for Transportation Packages Bernie White, Senior Project Manager Torre Taylor, Senior Project Manager NMSS/DSFM TWFN 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 Term Evaluated 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 Term Conclusion 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 Term Outreach 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 Term Outreach 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 for approved 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

- DSFM Office Instruction No. SFST-7, Rev. 4, Part 71 Guidance 10
