Overview of the United States Reactor Decommissioning Program Congressman Salud Carbajal (D- 29)

Public Meeting August 29, 2017 Bruce A. Watson, CHP Chief, Reactor Decommissioning Branch Office of Nuclear Material and Safeguards

NRCs Mission

• NRCs mission is to ensure plant safety, whether the plant is operating, or transitioning from operating to decommissioning, and through the entire process until the plant has been radiologically decommissioned and the license is terminated.

Present Status

• 6 Power Plants in active decommissioning

• 14 Power Plants in SAFSTOR

• 8 Announced, more shutdowns are anticipated 2

Reactor Decommissioning

• Reactor Decommissioning Background

• Decommissioning Process (10 CFR 50.82)

• Decommissioning Inspection Program

• Decommissioning Topics of High Public Interest

• Decommissioning Trust Funds

• Power Reactor Decommissioning in California

• Summary 3

Reactor Decommissioning Background

• Current 1997 decommissioning regulations are performance-based and risk-informed

• Extensive decommissioning experience

• A total of 10 power reactor sites have completed decommissioning:

Fort St. Vrain, Colorado Haddam Neck, Connecticut Maine Yankee, Maine Yankee-Rowe, Massachusetts Big Rock Point, Michigan Trojan, Oregon Rancho Seco, California Saxton, Pennsylvania Shoreham, New York Pathfinder, South Dakota 4

Decommissioning Process 10 CFR 50.82/Regulatory Guide 1.184

• Notification of intent to permanently shut down

• Submission of certifications of permanent shutdown and permanent removal of fuel from reactor vessel*

• Submittal of Post Shutdown Decommissioning Activities Report (PSDAR) and NRC public meeting

• Decommissioning must be completed within 60 years of permanent cessation of operations.

• License Termination Plan (LTP) is submitted 2 years prior to requesting license termination and NRC public meeting to obtain public comments on the LTP.

• NRC terminates the license by letter

• 2nd certification -- licensee cannot return fuel to the reactor and operate the plant 5

Decommissioning Program Regulatory Framework Decommissioning Decommissioning Program Process

• Statutory authority

• Integrated Decommissioning Program

• Comprehensive regulations:

• Public involvement

• Environmental review

• Financial assurance

• Site characterization

• Site remediation/Radiological clean-up

• Final site surveys

• Regulatory guidance

• Oversight and inspection 6

Reactor Decommissioning Program Status

• 10 power reactors have terminated their licenses and have been released for unrestricted use

• 20 power reactors in decommissioning

- 6 power reactors in active DECON (active dismantling):

• Zion 1 & 2 (IL), Humboldt Bay 3 (CA), LaCrosse (WI), and San Onofre 2

& 3 (CA)

- 14 power reactors in SAFSTOR (deferred dismantlement) with the addition of Fort Calhoun (NE) that ceased operations October 24, 2016 and is expected to select SAFSTOR

• 8 power reactors have announced they will permanently cease operations:

- Palisades (MI) and Three Mile Island 1 (PA) in 2018; Pilgrim (MA) and Oyster Creek (NJ) in 2019; Indian Point 2 & 3 (NY) in 2020/2021;and Diablo Canyon 1 & 2 (CA) by 2025/2026

- Additional near-term shutdowns are possible 7

Reactor Decommissioning Process Phase 1

• Reactor is permanently shut down and nuclear fuel is transferred to the spent fuel pool

• Plant is prepared for decommissioning

• Modifications are typically made to facilitate decommissioning 8

Reactor Decommissioning Process Phase 1 (Continued)

Post Shutdown Decommissioning Activities Report (PSDAR) (Reg Guide 1.185)

• Decommissioning strategy - DECON or SAFSTOR - 60 years to complete decommissioning

• Site Decommissioning Funding Status

• Affirmation of the Environmental Review NRC holds Public Meeting for comments NRC does not approve the PSDAR 9

Reactor Decommissioning Process Phase 2 - Decommissioning Phase

• DECON - immediate dismantlement

• SAFSTOR - deferred dismantlement

• 60 years to complete (50 years for radioactive decay + 10 years to dismantle)

Phase 3 - last 2 years

• License Termination Plan (License Amendment)

• NRC holds a Public Meeting 10

Reactor Decommissioning Inspection Program

• Continues until the license is terminated

• Inspection Manual Chapter 2561

• 40 inspection procedures

• Minimum annual inspection - 12 core procedures are required each year

• Resident Inspector up to 1 year after shutdown, but can be extended

• Inspection Reports are publically available 11

Trojan, Oregon 12

Big Rock Point -

Charlevoix, Michigan 13

Yankee-Rowe -

Rowe, Massachusetts 14

Maine Yankee -

Wiscasset, Maine 15

Connecticut Yankee Haddam Neck, Connecticut 16

Zion 1 & 2 - New Business Model Progress and Expected End Point 17

Decommissioning Topics of High Public Interest

• Economic losses to the local community

- Loss of Jobs and Tax Revenues

- Employee Retention

• Community involvement - advisory groups

• High-level waste time in storage and transport

• Interim Spent Fuel Storage Installations (ISFSI)

• Reactor decommissioning - timeliness - 60 years to complete

• Reductions in emergency plans

• Decommissioning fund adequacy

• Future use of the site 18

Reasonable Assurance of Decommissioning Funding

• Initial certification of financial assurance

• Maintains the NRC Minimum Funding Amounts throughout the life of the reactor

• Uses one or more funding methods specified in the regulation

• Monitoring and updating of decommissioning funding -

Operating licensee provides decommissioning fund status report to the NRC (every 2 years)

Licensee must provide Site Specific Cost Estimate 5 years prior to permanent cessation of operations &

in PSDAR 19

Rancho Seco -

Sacramento, California 20

San Onofre - San Clemente, CA 21

Humboldt Bay - Eureka, CA 22

GE Vallecitos - Pleasanton, CA 23

Diablo Canyon 1, 2

• Location: Avila Beach, CA (12 miles WSW of San Luis Obispo, CA) in Region IV Operator: Pacific Gas & Electric Co.

Unit 1

• Operating License: Issued - 11/02/1984 License Expires: 11/02/2024 Docket Number: 05000275

• Reactor Type: Pressurized Water Reactor Licensed MWt: 3,411 Reactor Vendor/Type: Westinghouse Four-Loop Containment Type: Dry, Ambient Pressure Unit 2

• Operating License: Issued - 08/26/1985 License Expires: 08/26/2025 Docket Number: 05000323

Summary NRCs mission is to ensure plant safety, whether the plant is operating, or transitioning from operating to decommissioning, and through the entire process until the plant has been radiologically decommissioned and the license is terminated.

Present Status

• 6 power plants in active decommissioning

• 14 power plants in SAFSTOR

• More shutdowns are anticipated 25
