Three Mile Island Unit 2 Environmental Regulatory Approach to TMI-2 Decommissioning NUCLEAR Presented to the U.S. Nuclear Regulatory Commission February 20, 2020
Purpose NUCLEAR
- Provide brief history of TMI-2
- Accident, cleanup, PDMS
- Current setting
- Describe TMI-2Solutions/GPU Nuclear current evaluation on environmental compliance for transition to DECON
- Gather insight/feedback from NRC staff
Introductions NUCLEAR Affiliation Name Title Greg Halnon President/Chief Nuclear Officer GPU Nuclear Mike Casey TMI-2 Project Manager Beth Wetzel Licensing Manager Jim Byrne Decommissioning Manager Ron Worster TMI-2 Project Director TMI-2Solutions Gerry van Noordennen V.P. Regulatory Affairs Kim Anthony Environmental Manager 3
Brief History of TMI-2 NUCLEAR
- Construction permit November 1969
- Operating license February 1978
- Cleanup and DOE acceptance of ~99% of damaged core material 1990
Reg Approach to Accident Cleanup NUCLEAR
- Programmatic Environmental Impact Statement (PEIS) and Supplements 1 - 3
- Analyzed four major activities
- 1. Building and equipment decontamination
- 2. Fuel removal and decontamination of the primary coolant system
- 3. Treatment of radioactive liquids
- 4. Packaging, handling, storage and transportation of radioactive wastes 5
Reg Approach to Accident Cleanup NUCLEAR
- PEIS Main Report: Occupational dose most significant environmental impact of cleanup
- Re-evaluation of occupational dose and resulting health effects from cleanup
- Updated environmental evaluation of accident-generated water disposal alternatives
- Updated environmental evaluation of proposed cleanup effort, PDMS and alternatives 6
Reg Approach to Accident Cleanup NUCLEAR
- PEIS Supplement 3 alternatives included:
- Immediate or delayed cleanup of remaining 1% of accident waste
- Immediate or delayed full decommissioning
- Length of stay in PDMS
- No alternative superior, all bound by PEIS
- Delayed Cleanup Alternative
- Selected course of action
- PDMS followed by completion of cleanup 7
TMI-2 Chronology NUCLEAR Dec. 30, 1978 Commercial Operations Sept. 14, 1993 POL issued Mar. 28, 1979 LOCA Accident Dec. 1993 Entry into PDMS CLEANUP OPERATIONS PDMS 1981 Programmatic Environmental Impact Statement 1984 Supplement 1: Occupational Radiation Dose 1987 Supplement 2: Accident-Generated Water 1989 Supplement 3: PDMS and Subsequent Cleanup 8
TMI-2 Current Setting NUCLEAR Dec. 30, 1978 Commercial Operations Sept. 14, 1993 POL issued Mar. 28, 1979 LOCA Accident Entry into DECON Dec. 1993 Commencement Entry into PDMS of Phase 1b CLEANUP OPERATIONS PDMS DECON 1981 Programmatic Environmental Impact Statement 1984 Supplement 1: Occupational Radiation Dose Today 1987 Supplement 2: Accident-Generated Water 1989 Supplement 3: PDMS and Subsequent Cleanup 9
TMI-2 Work Phases NUCLEAR PDMS TMI-2 DECON 1993 Today Phase 1a Phase 1b Phase 2 Phase 3 Phase 1a: Licensing, planning, engineering, transition (occurring now)
Phase 1b: Source term reduction (e.g., retrieval of remaining core debris)
Phase 2: Typical D&D, reduce licensed footprint to storage area only Phase 3: Core debris management, license termination, site restoration 10
2020 Submittals NUCLEAR Entry into DECON PDMS DECON Today Between Today and entry into DECON, two submittals to NRC, each requiring environmental review:
- 1. PSDAR Rev. 4
- Update decom activities and environmental impacts
- 2. LAR for PDMS to DECON
- Transition from PDMS to DECON
Environmental: Potential Pathways NUCLEAR PDMS TMI-2 DECON Today Phase 1b Phase 2 Phase 3 Existing Analyses Existing Analyses (e.g., NUREG-0586) (e.g., NUREG-2157, NUREG-1496)
PSDAR LAR PEIS CATEX EA Supplmt LAR Approval 12
Environmental: Proposed Pathway NUCLEAR PDMS TMI-2 DECON Today Phase Phase 1b 1b Phase 2 Phase 3 Existing Analyses Existing Analyses (e.g., NUREG-0586) (e.g., NUREG-2157, NUREG-1496)
PSDAR LAR PEIS CATEX EA Supplmt LAR Approval 13
Ongoing Evaluation of Current EISs NUCLEAR
- Credit previously issued environmental analyses
- Compare existing analyses to current decommissioning plan, including:
- Scope of PEIS discussion
- Potential methods and technologies
- Potential changes in population
- Potential changed impacts
- e.g., T&E species, air quality impacts 14
Decom GEIS Applicability NUCLEAR
- Decommissioning GEIS (NUREG-0586) issued in 1988, supplemented in 2002 decommissioning activities following shutdown of a facility after a major accident resulting in significant contamination of the site are outside the scope of this Supplement. For most types of accidents, decommissioning would be treated on a site-specific basis and, therefore, cannot be considered in a generic sense.
- However, endpoint of Phase 1b will be a radiological condition similar to an operating plant at the end of its operating life that has not undergone an accident
- Justification for reliance on GEIS will be provided in environmental reviews in PSDAR Rev. 4 and LAR submittals 15
Submittal Schedule NUCLEAR Activity Date Submitted License Transfer Application Nov. 12, 2019 Submitted PSDAR Rev. 3 Dec. 12, 2019
- Submit PSDAR Rev. 4 Q4 2020
- Submit LAR (PDMS to DECON) Q4 2020
- Q4 2020 submittals are contingent upon LTA approval and the closing date occurs as scheduled 16
