Substantial Progress in Licensing Timeliness and Completions

(16)

Strengthened Workload Management

• Applied additional resources

• Greater management oversight on workflow process

– Periodic status meetings

– Lessons learned on specific licensing actions

– Review of licensing and acceptance review processes

(17)

Updating Data Management and Tools

• Replacement Reactor Program System (RRPS)

• Procedure revision

• Workload forecasting - RIS 2015-16

(18)

Revised Expectations to Staff

• Re-emphasized process adherence and incorporated lessons learned

• Clarified process for requests for additional information

– Draft SE prior to RAI issuance – Consideration of alternatives

– Enhanced management involvement – Review of responses for scope

changes

(19)

Rebaselining – Efficiency Efforts in Progress

• Eliminated commitment audits and UFSAR Reviews

• 2.206 process enhancements

• Implementing electronic

correspondence and concurrence

• Streamlined briefing packages

(20)

Changing Environment Creates New Opportunities

• Aligning the organization for future work

• Continuing to identify licensing process efficiencies in order to sustain

performance

• Harmonizing processes and procedures between operating and new reactors

• Integrating greater use of risk insights into processes and procedures

• Maintaining focus on safety, security, and preparedness

(21)

A Risk-Informed Approach for Addressing Low Risk

Compliance Issues

Rob Elliott

Division of Safety Systems Office of Nuclear Reactor

Regulation

(22)

Continued Progress Integrating Risk-Informed Decision-making

• Current risk-informed programs:

– Reactor Oversight Program

– Risk-informed completion time and

surveillance frequency control programs – Notices of enforcement discretion

• Some licensing basis design issues are not immediate safety concerns

• TS-driven urgency to resolve these

issues may not result in best solution or use of staff and licensee resources

(23)

Applying Risk-Informed Solutions

• Tornado Missile Protection:

– Generic problem identified – Low probability event

– Significantly lower probability of loss of safety function

– Timely compliance concerns drove plant and NRC response actions

• Solution:

– Enforcement Guidance

Memorandum (EGM) 2015-002 – Risk informed to allow

appropriate time to take corrective actions

23

(24)

A New Risk-Informed Regulatory Tool is Under Consideration

• Applying TS completion times to low risk, low safety-significant design issues can lead to unnecessary regulatory burden

• Working group with staff from NRR, OGC, OE, and the Regions

• Considering a new plant-specific process:

– Evaluation of risk, defense-in-depth, safety margins, compensatory measures and risk management actions

– Potential for enforcement discretion

• Stakeholder involvement during process development

(25)

Potential Benefits

• Implement timely corrective action

commensurate with safety significance

• Ensure continued safe operation

• Focus resources on safety significant issues

• Complementary to existing regulatory processes

• Consistent with existing Enforcement Policy

25

(26)

Next Steps

• Continue consideration of a new risk- informed process that:

– addresses low risk/low safety significance design issues affecting operability

– potentially utilizes enforcement discretion – ensures safe operation while the licensee

implements corrective action

• Continued stakeholder engagement

• Keep Commission informed
