What is meant by Attractiveness?
Dilution Factor - measure of attractiveness The mass of the fissile material divided by the total mass of the fissile material and non-fissile materials (that are not mechanically separable from the fissile material, for solids)
Non-dilute Moderately dilute Highly dilute Risk-informed concept The less dilute the material, the more attractive it is to adversaries 5
Issue D Physical Protection for Category I and III SNM
Why focus on Category I and III SNM?
Current regulatory framework (regulations + orders + voluntary upgrades) provides adequate protection of public health and safety and the common defense and security.
Facilities with Category I quantities of SNM Make generally applicable existing exemptions; reduce need for future exemptions Additional flexibility to reduce physical protection for material with lower improvised nuclear device (IND) risks, i.e., via dilution factors Facilities with Category I and Category III quantities of SNM Address current understanding of the threat environment Improve regulatory reliability and clarity for licensees and potential applicants Facilities with Category III quantities of SNM Ensure that physical protection regulations fully consider International Atomic Energy Agencys Information Circular (INFCIRC)/225/Rev. 5 7
Facilities potentially affected by changes to requirements for Category I and III quantities of SNM 8
Licensee Type Naval Fuel Facilities / Future Reprocessing Facilities Other Fuel Cycle Facilities Research and Test Reactor facilities Greater than Critical Mass licensees Limited number of Agreement State Licensees
NO RULEMAKING FOR CATEGORY I OR CATEGORY III SNM Option 1 OPTION 2A Consider SNM attractiveness, Category I and III orders, and INFCIRC/225/Rev. 5 OPTION 2B Performance-based regulations for Category I SNM; account for security orders and SNM attractiveness RULEMAKING Options 2A and 2B What are the options the staff is considering for physical protection of Category I and Category III SNM (Issue D)?
9
What would happen if there were no rulemaking for Category I and III SNM (Option 1)?
10
- Staff would use existing regulations and guidance to conduct licensing reviews
- Security orders would remain in place
- Staff would employ a case-by-case approach
Advantages/Disadvantages of no rulemaking (Option 1) 11
- Advantage
- Involves no expenditure of resources for rulemaking
- Disadvantages
- Does not consider the most current guidance for physical protection of Category III SNM in INFCIRC/225/Rev. 5
- Does not enhance licensees/applicants ability to implement a flexible approach to physical protection for Category I SNM within the regulations without an exemption request
- Limits regulatory reliability and clarity with a mix of regulations and orders
What would happen if rulemaking proceeded considering SNM attractiveness, security orders, INFCIRC/225/Rev. 5 (Option 2A)?
12
- Staff would recommend that a small number of new measures be added to the regulations to make the existing Category III SNM regulations more complete in describing a comprehensive security program and fully consider INFCIRC/225/Rev. 5
- Staff would recommend using SNM attractiveness, via dilution factors, to allow licensees to reduce the level of protection for Category I quantities of SNM commensurate with the lower IND risk associated with that material
Examples of potential outcomes for Category III SNM (Option 2A) 13 Additional Comprehensive Program Items Consideration of INFCIRC/225/Rev. 5 Issue tracking system Safety-security interface Identify security manager and individual responsible to direct security activities Security implementing procedures Secure and monitor openings in barriers Trained and qualified security organization Document access authorization program Limit access to Controlled Access Area Escorted access permitted Control of keys, locks, and passwords Communication capability with onsite and offsite resources Establish a maintenance, testing and calibration program Agreements of local law enforcement Familiarize response forces with the site Establish eminent threat procedure
Examples of potential outcomes for Category I SNM (Option 2A)
- Security order requirements would be made generally applicable in the regulations
- Security orders would be rescinded
- SNM attractiveness would establish three levels of protection correlating to the dilution factor approach (non-dilute, moderately-dilute, and highly-dilute)
- Voluntary upgrades would remain in place outside the regulatory framework 14
Advantages of rulemaking considering SNM attractiveness (Option 2A) 15
- Rulemaking process allows for broader engagement with stakeholder community on potential improvements to risk-inform security
- Increases regulatory reliability and clarity for applicants and licensees
- SNM attractiveness can provide gradation of physical protection measures by dilution (risk-informed)
- Ensures full consideration of international guidance
Disadvantages of rulemaking considering SNM attractiveness (Option 2A) 16
- Requires significant time and financial resource expenditure for rulemaking
- Does not permit all voluntary Category I enhancements, i.e., not associated with orders, to be added to the regulations
What would happen if rulemaking proceeded, implementing performance-based regulations for Category I SNM (Option 2B)?
17
- Staff would recommend more performance-based regulations than the series of prescriptive measures staff proposed in previous analyses
- Physical protection system would be based on threat and site-specific vulnerability assessments
- Physical protection requirements for Category III quantities of SNM would not be revised
Examples of potential outcomes - Revise regulations to be more performance-based (Option 2B) 18
- Licensees/applicants would need to perform analyses to support documentation of physical protection systems
- Security plans would need to be revised based on performance objectives rather than existing requirements
Advantages of rulemaking implementing performance-based regulations for Category I SNM (Option 2B) 19
- Increases regulatory flexibility for Category I licensees to implement facility-specific security based on site specific vulnerability and diversion path analyses
- Permits Category I security orders to be rescinded and allows the inclusion of voluntary upgrades into the regulations, per Commission direction
- Involves a risk-informed approach
Disadvantages of rulemaking implementing performance-based regulations for Category I SNM (Option 2B) 20
- Requires expenditure of NRC staff resources for rulemaking
- NRC inspection program would need to be adjusted to account for performance-based flexibility
Issue C Alternate Nuclear Material
Why focus on alternate nuclear material?
- NRC regulations do not address physical protection for ANM
- ANM can be used to create an IND
- Not currently possessed by NRC licensees in sufficient quantities to consider IND risk
- Reprocessing activities could produce kilogram quantities of separated ANM
- In SRM-SECY-09-0123, the Commission deferred the staffs recommendation to develop regulations for physical protection and material control and accounting (MC&A) for ANM
- DOE requires physical protection and MC&A of ANM*
22
- See DOE O473.1A and O474.2
Why focus on alternate nuclear material (cont.)?
- NRC regulations do not address physical protection for ANM
- In the past, advanced reactor applicants indicated limited near-term interest (within the next decade or two) in the use of reprocessed spent fuel
- More recent staff interaction with advanced reactor stakeholders indicates an interest in using reprocessing technology
- 2022 National Academies of Sciences, Engineering and Medicine report*
recommendation: [a rulemaking]would provide an opportunity to clarify the attractiveness of all materials that may be present in advanced reactor fuel cycles and the appropriate levels of security to apply to them.
23
OPTION 2A Rulemaking for PP and MC&A for ANM OPTION 2B Rulemaking for PP of ANM; Defer MC&A RULEMAKING FOR ANM Options 2A and 2B What are the options the staff is considering for physical protection and MC&A for ANM (Issue C)?
OPTION 1A Status Quo - No Rulemaking for either PP or MC&A OPTION 1B Defer rulemaking until there is an application for reprocessing NO IMMEDIATE RULEMAKING FOR ANM Options 1A and 1B 24
What would happen if there were no rulemaking for ANM (Option 1A)?
25
- If the NRC received a license application for a reprocessing facility, staff would continue to employ a case-by-case approach to determine the appropriate physical protection and MC&A requirements
- Physical protection and MC&A could be applied based on the characteristics of ANM (potentially considering attractiveness) rather than the facility that possesses it
- Staff could consider supplemental security measures via orders
Advantages/Disadvantages of no rulemaking for ANM (Option 1A) 26
- Advantages
- Involves no expenditure of resources on rulemaking for physical protection or MC&A for ANM
- Disadvantages
- Decreases regulatory transparency and clarity for applicants and licensees
- Could result in extended staff review time and additional resources for an application due to development of orders, exemptions and/or license conditions
What would happen if rulemaking for ANM were deferred until an application was submitted for a reprocessing facility (Option 1B)?
27
- Licensing a future reprocessing facility may require orders, exemptions, and license conditions to address any regulatory gaps
- Staff would leverage the gap analysis as referenced in SECY 0026, Discontinuation of Rulemaking - Spent Fuel Reprocessing, dated March 19, 2021 (ML20301A388)
Advantages/Disadvantages of deferring rulemaking for ANM (Option 1B) 28
- Advantages
- Involves no expenditure of resources on rulemaking for physical protection or MC&A for ANM
- Allows staff more time to assess industry interest in reprocessing facilities
- Disadvantages
- Decreases regulatory transparency and clarity for applicants and licensees
- Could result in extended staff review time and additional resources for an application due to development of orders, exemptions and/or license conditions
What would happen if there were a rulemaking for physical protection and MC&A for ANM (Option 2A)?
- Staff would draft both physical protection and MC&A regulations for ANM
- Staff would likely propose physical protection and MC&A for ANM be regulated similarly to Category I or II quantities of highly enriched uranium (HEU)
- The staff would specify the nuclides constituting ANM in regulations 29
Advantages of rulemaking for physical protection and MC&A for ANM (Option 2A)
- Rulemaking process allows for broader engagement with stakeholder community on potential measures to risk-inform physical protection and MC&A for ANM
- Increases regulatory reliability and clarity for applicants and licensees
- Incurs minimal additional NRC staff resources for physical protection - staff has analyzed technical information
- Aligns with 2022 National Academies report recommendation to conduct a rulemaking on weapons-useable materials 30
Disadvantages of rulemaking for physical protection and MC&A for ANM (Option 2A) 31
- Addressing the MC&A for ANM in a rulemaking effort would incur additional resources for staff to perform associated technical analysis
- No immediate benefit (no current application for a reprocessing facility)
- Requires modifications to Nuclear Materials Management and Safeguards System (NMMSS) reporting system
- If combined with an SNM rulemaking, could increase the complexity and delay the process
What would happen if there were rulemaking for physical protection for ANM, but MC&A were deferred (Option 2B) ?
32
- Staff would draft physical protection regulations for ANM
- Staff would likely propose physical protection for ANM be regulated similarly to Category I or II quantities of HEU
Advantages of rulemaking for physical protection for ANM, but deferring MC&A (Option 2B)
- Rulemaking process allows for broader engagement with stakeholder community on potential measures to risk-inform physical protection for ANM
- Increases regulatory reliability and clarity for applicants and licensees
- Incurs minimal additional NRC staff resources for physical protection
- staff has analyzed technical information
- Avoids rulemaking costs for MC&A aspects
- Aligns with 2022 National Academies report recommendation 33
Disadvantages of rulemaking for physical protection for ANM, but deferring MC&A (Option 2B) 34
- No immediate benefit (no current application for a reprocessing facility)
- If combined with an SNM rulemaking, could increase the complexity and delay the process
