Overview of the Current Fuel Overview of the Current Fuel Cycle Oversight Process Cycle Oversight Process (Cont.)

(Cont.)

  • Current program is adequate to

ensure safety and security

  • Current program is evolving,

slow ly, w ithin existing framew ork

  • Approach to improvements can

be better focused, more effective and efficient

Purpose of Oversight Revision Purpose of Oversight Revision Project Project

  • To improve program effectiveness and

efficiency

  • To make the process more

– Risk-Informed – Performance-Based – Predictable – Transparent

Risk Informed & Performance Risk Informed & Performance Based– Current Program Based– Current Program

  • Inspection

– Use of Integrated Safety Analyses (ISA) during inspection planning improves risk focus – Programmatic approach still used in some areas

  • Enforcement

– Proposed policy is more ISA-informed

  • Assessment

– Process allow s for integration of enforcement actions – Some consideration of risk

Risk Informed & Performance Risk Informed & Performance Based– Current Program Based– Current Program

Predictability – Current Predictability – Current Program Program

  • Inspection

– Reactive and initiative inspection decisions lack clear thresholds

  • Enforcement

– Variability in ISA methods presents a challenge

Predictability – Current Predictability – Current Program Program

  • Assessment

– Relationship betw een NRC inspection effort, assessment periodicity, and enforcement history is not w ell defined – Assessment process lacks thresholds for specific licensee and NRC actions

Transparency – Current Transparency – Current Program Program

  • Inspection

– Inspection and enforcement results are generally publicly available – Use of w ebpage to present process and outcomes can be improved

  • Enforcement

– Consideration of risk escalators and mitigators not transparent

Alternative Approaches Alternative Approaches

  • Proposal aligned to ROP principles
  • Other options include:

– Maintain current approach w ith evolving processes – Modest enhancements to current process – Phased revision over longer period

Conclusion Conclusion

  • Current process is adequate but

needs to be improved

  • Proposed improvements w ould

use existing ISA’s

  • Proposed implementation in 2014
