Federal Register (80 FR 72358), November 19, 2015 5
Decommissioning Rulemaking
- 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:
Maintain reasonable assurance Maintain defense-in-depth Provide regulatory certainty and clarity 6
Decommissioning Levels 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 7
Decommissioning EP Levels Operating Reactor Emergency Plan 8
EP Planning Basis
- 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 9
Research to Support Rulemaking
- 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 10
Decommissioning Rulemaking
- 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 11
Decommissioning Rule Schedule 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 12
- Rulemaking to develop a clear set of rules and guidance for small modular reactors (SMRs) and other new technologies (ONT)
Technology Neutral Risk-Informed, Performance Based Principle of dose-at-distance and consequence-oriented approach to determine EPZ size 13
SMR & ONT Rulemaking
- 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 14
SMR & ONT Rulemaking Schedule 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 15
NUREG-0654/FEMA-REP-1 Revision Timeline 2018 2016 Issue Revision 2 after final Comment management concurrence 2015 adjudication and and OMB review Distribution of draft Revision 2 draft Revision 2 rewrite/adjustments 2013 for public comment Revision 2 development 16
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
- Identification of radiological hot spots
- Drinking water safety
- Relaxation of evacuation and
- Beyond the 10-mile emergency relocation orders planning zone (EPZ)
- Food condemnation or embargo
- Notable observations Outcome NUREG/CR-7248 report to be published soon.
17
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
- 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 consequences Studies to Inform Regulations or Guidance
- EPZ Size Methodology of NUREG-0396
- Non-radiological impacts of evacuations
- MACCS model improvements Consequence Studies
- Sequoyah SOARCA
- Level 3 PRA 19
Back to the Future EP is evolving, but the NRCs 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
