NRC Emergency Preparedness Rulemaking ActivitiesTri-State Directors MeetingFramingham, MAMay 8, 2019Todd Smith, PhDEmergency Preparedness SpecialistU.S. Nuclear Regulatory Commission What is Emergency Preparedness?
2*EP is a defense
-in-depth program
- EP is the last line of defense
- EP addresses a spectrum of potential accidents*EP requires constant state of readiness
- The scope and nature of the preparedness depends on the potential hazards presented by the class of facility What is changing and why?
3*EPZ size and other radiological emergency preparedness (REP) Program capabilities should be proportional to the risk without undue regulatory burden on licensees
- Performance
-based emergency preparedness (EP) and scalable EPZ size commensurate with risk
- Ingestion planning capabilities rather than defined zone
- New designs/technologies are including additional features to meet the expectations of the Commission Policy Statement on Advanced Reactors, issued in 2008
- NRC as a matter of long standing principle has licensed facilities such as research and test reactors, reactors at low power operation, and fuel facilities with EPZs that do not require an off
-site REP program Philosophy of EP 4The overall objective of EP is to provide dose savings for a spectrum of accidents that could produce offsite doses in excess of Protective Action Guides.EPZs are areas for which planning is needed to assure that prompt and effective actions can be taken to protect the public in the event of an accident.How is this applied in rulemaking?
- Maintain reasonable assurance of adequate protection of the public health and safety
- Maintain EP as an independent layer of defense-in-depth*Provide regulatory certainty and clarity
- Gain efficiencies from previous efforts
- Exemption requests
- Prior decommissioning rulemaking efforts
- Supporting studiesRulemaking Goals for EP 5
6Illustrative Milestones 7Supporting ResearchThree recent analyses that support the planning basis for EP:
- Analysis of Mitigative Actions
- Spent Fuel Decay Time
- Dose Rate of Accidental Radiological Release from Spent Fuel Pool Graded Approach to EP 8Level 1Post Shutdown Emergency Plan(PSEP)10 months (BWR) 16months (PWR)Level 2Permanently Defueled Emergency Plan(PDEP)Level 3ISFSI Only EmergencyPlan (IOEP)> 5 years Cessation of Power Operations and DefueledPower OperationsLevel 4No Spent Fuel Onsite EP Basis for Decommissioning Sites 9The overall objective of EP is to provide dose savings for a spectrum of accidentsthat could produce offsite dosesin excess of PAGs.EPZs are areas for which planning is needed to assure that promptand effective actions can be taken to protect the public in the event of an accident.For example, in Level 2 decommissioning:
- The spectrum of accidents are fewer
- DBAs will not exceed 1 Rem offsite
- At least 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> available before a SFP fire could occur
- Proposed graded approach to EP
-Establishes requirements commensurate with radiological risk
-Minimizes licensing actions and maintains reasonable assurance
-Upholds EP as an independent layer of defense
-in-depth*Coordination with offsite agencies maintained
-Arrangements for offsite services support
-Communications maintained and tested periodically
-Annual review of Emergency Action Levels (EALs)
-Radiological orientation training program for local services
-Voluntary participation in exercises

-2015-0070
- Rulemaking to develop a clear set of rules and guidance for small modular reactors (SMRs) and other new technologies (ONT)
- New designs/technologies are including features to enhance the margin of safety through use of simple, inherent, or passive means to accomplish their safety and security functions.Principle of dose
-at-distance and consequence
-oriented approach to determine EPZ sizeRisk-Informed, Performance BasedTechnology NeutralEP for SMRs & ONT 12 Commission Policy Statement on Advanced Reactors"the Commission expects, as a minimum, at least the same degree of protection of the environment and public health and safety and the common defense and security that is required for current generation light
-water reactors (LWRs)- the Commission expects that advanced reactors will provide enhancedmargins of safety and/or use simplified, inherent, passive, or other innovative means to accomplish their safety and security functions." (emphasis added)
Major Provisions
- Technology
-inclusive for future SMRs and ONTs, including medical radioisotope facilities and non
-light-water reactors

-PAG and planning relationship
-Consistent with the existing graded
-approach afforded to:

- Fuel cycle facilities
- Independent spent fuel storage installations
- Same level of protection afforded to public health and safety
