• EP regulations do not address risk at permanently shutdown and defueled reactor sites

• Exemptions from regulations provide relief on a case-by-case basis

• Commission directed rulemaking to include consideration of a graded approach to EP (SRM SECY-14-0118)*Rulemaking goals:Decommissioning Rulemaking 6Maintain reasonable assuranceMaintain defense

-in-depthProvide regulatory certainty and clarity Level 1 -Permanent cessation of operations and all fuel in spent fuel poolLevel 2 -Spent fuel has sufficiently decayed (10 hour1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> adiabatic heatup time)Level 3 -All fuel is in dry cask storageLevel 4 -All fuel removed from siteDecommissioning Levels 7

Decommissioning EP Levels 8Operating Reactor Emergency Plan EP Planning Basis 9*The overall objective of EP is to provide dose savings for a spectrum of accidentsthat could produce offsite dosesin excess of PAGs

• Planning basis elements consider distance, timing, materials*EPZsare 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

• After permanent cessation of operations:The spectrum of accidents are fewerDBAs will not exceed EPA PAGs offsiteAt least 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> available before release occurs

• NUREG-1738, "Technical Study of Spent Fuel Pool Accident Risk at Decommissioning Nuclear Power Plants"

• NUREG-2161, "Consequence Study of a Beyond

-Design-Basis Earthquake Affecting the Spent Fuel Pool for a U.S. Mark I Boiling Water Reactor"

• Supporting Research Studies (ADAMS ML16110A416)

• Analysis of Mitigative Actions*Spent Fuel Decay Time*Dose Rate of Accidental Radiological Release from Spent Fuel PoolResearch to Support Rulemaking 10

• Implementation of a graded approach to EP

-Regulatory standards commensurate with radiological risk

-Continued coordination with offsite response organizations

-Consistent with approved EP exemptions but based on considerations of EP as a separate layer of defense

-in-depth*Emergency Plan Change Process

-Transition to Levels

-Changes within Levels

-Changes in FSAR

-Changes in EAL Classifications and Scheme(s)

• Draft Regulatory Guide to accompany proposed ruleDecommissioning Rulemaking 11 Advance Notice of Proposed Rulemaking

-November 19, 2015Draft Regulatory Basis

-March 15, 2017Final Regulatory Basis

-November 2017 (ML17215A010)Proposed Rule/Draft Regulatory Guidance

-Provide to Commission in May 2018

-Public Comment Period in December 2018Final Rule/Final Regulatory Guidance

-Goal: Provide to Commission CY 2019Decommissioning Rule Schedule 12

• Rulemaking to develop a clear set of rules and guidance for small modular reactors (SMRs) and other new technologies (ONT

• Rule would consider

-Event classification and mitigation

-Protective actions

-Communications

-Command and control

-Staffing-Radiological assessment

• Guidance-General information (non

-design specific)

-Design specific guidance would be developed after rulemakingSMR & ONT Rulemaking 14 Draft Regulatory Basis

17*Identification of radiological hot spots*Relaxation of evacuation and relocation orders

• Food condemnation or embargo*Drinking water safety

• Beyond the 10-mile emergency planning zone (EPZ)

• Notable observations Evacuation Time Estimate (ETE) StudyApplied research study to examine topics associated with the modeling and simulation of evacuations and independent verification of the NRC's methodology for ETE developmentStudy Areas

• Shadow evacuation analysis

• Distance of evacuation travel

• Manual traffic control*Determination of variable importanceOutcome*NUREG/CR report published late 2018

• NUREG/CR-7002 update prior to 2020 census 18 EP Research The NRC is conducting a number of research studies to inform emergency preparedness regulations or guidance and to assess the impact of EP in reducing consequencesStudies to Inform Regulations or Guidance

• EPZ Size Methodology of NUREG

-0396*Non-radiological impacts of evacuations

• MACCS model improvementsConsequence Studies

• Sequoyah SOARCA

• Level 3 PRA 19 Back to the FutureEP is evolving, but the NRC's mission to protect the health and safety of the public remains the same*EP of the past informs the future-NUREG-0396 planning basis

• Guidance updates incorporate decades of experience

• Research enhances our understanding and informs and validates our technical approach 20 Contact InformationTodd Smith, PhDEd RoachEP SpecialistSenior EP SpecialistNSIR/DPR/POBNSIR/DPR/POB(301)-287-3744(301) 287-9229todd.Smith@nrc.goved.roach@nrc.govRobert Kahler, ChiefNSIR/DPR/POB(301) 287-3756robert.kahler.@nrc.gov 21
