Decommissioning Topics 5

Emergency Preparedness Physical Security Fitness for Duty Requirements for Certified Fuel Handlers Regulatory Approach for Decommissioning Application of Backfitting Protection Decommissioning Trust Funds Offsite and Onsite Liability Protection General Questions (e.g.,

Cumulative Effects of Regulation)

Federal Register (80 FR 72358), November 19, 2015

  • 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 6

Maintain reasonable assurance Maintain defense-in-depth Provide regulatory certainty and clarity

Level 1 Permanent cessation of operations and all fuel in spent fuel pool Level 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 storage Level 4 All fuel removed from site Decommissioning Levels 7

Decommissioning EP Levels 8

Operating Reactor Emergency Plan

EP Planning Basis 9

  • The overall objective of EP is to provide dose savings for a spectrum of accidents that could produce offsite doses in excess of PAGs
  • Planning basis elements consider distance, timing, materials
  • 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
  • After permanent cessation of operations:

The spectrum of accidents are fewer DBAs will not exceed EPA PAGs 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 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 Pool Research 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 rule Decommissioning Rulemaking 11

Advance Notice of Proposed Rulemaking November 19, 2015 Draft Regulatory Basis March 15, 2017 Final Regulatory Basis November 2017 (ML17215A010)

Proposed Rule/Draft Regulatory Guidance Provide to Commission in May 2018 Public Comment Period in December 2018 Final Rule/Final Regulatory Guidance Goal: Provide to Commission CY 2019 Decommissioning Rule Schedule 12

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

Principle of dose-at-distance and consequence-oriented approach to determine EPZ size Risk-Informed, Performance Based Technology Neutral EP for SMRs & ONT 13

  • 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 rulemaking SMR & ONT Rulemaking 14

Draft Regulatory Basis April, 2017 Final Regulatory Basis November 2017 (ML17206A265)

ACRS Subcommittee meeting August 2018 ACRS full meeting October 2018 Commission Submission October 2019 Proposed Rule/Draft Regulatory Guidance January 2019 SMR & ONT Rulemaking Schedule 15

NUREG-0654/FEMA-REP-1 Revision Timeline 16 2013 Revision 2 development 2015 Distribution of draft Revision 2 for public comment 2016 Comment adjudication and draft Revision 2 rewrite/adjustments 2018 Issue Revision 2 after final management concurrence and OMB review

ORO Study The NRC seeks to better understand offsite response organization (ORO) capabilities and practices for protective actions in the intermediate phase of emergency response to a nuclear power plant (NPP) incident Study Areas Outcome NUREG/CR-7248 report to be published soon.

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) Study Applied research study to examine topics associated with the modeling and simulation of evacuations and independent verification of the NRCs methodology for ETE development Study Areas

  • Shadow evacuation analysis
  • Distance of evacuation travel
  • Manual traffic control
  • Determination of variable importance Outcome
  • NUREG/CR report published late 2018

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 consequences Studies to Inform Regulations or Guidance

  • Non-radiological impacts of evacuations
  • MACCS model improvements Consequence Studies
  • Sequoyah SOARCA

Back to the Future EP is evolving, but the NRCs mission to protect the health and safety of the public remains the same

  • Guidance updates incorporate decades of experience
  • Research enhances our understanding and informs and validates our technical approach 20
