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
- 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
