U.S. Nuclear Regulatory Commission -

An Independent Regulatory Agency NRC MISSION We license and regulate U.S. civilian use of radioactive materials, protecting public health and safety, promoting the nations common defense and security, and protecting the environment STATUTORY AUTHORITY Atomic Energy Act of 1954 Energy Reorganization Act of 1974 split the Atomic Energy Commission into the NRC and the predecessor of the Energy Department 5

Strategic Plan Fiscal Year 2022-2026

Diablo Canyon License Renewal

  • The license renewal application for the Diablo Canyon Nuclear Power Plant, Units 1 and 2 (Diablo Canyon) was submitted on November 7, 2023
  • The current license expiration dates for Diablo Canyon Units 1 and 2 are November 2, 2024, and August 26, 2025, respectively
  • Both operating licenses are in timely renewal; therefore, they will remain valid until the NRC has made a final determination on the application

Environmental Review

  • Generic Environmental Impact Statement (GEIS)

- Addresses Category 1 environmental issues common to all plants (or a distinct subset of plants) during the license renewal term

  • Environmental Impact Statement

- Neither the applicant nor the NRC identified information that is both new and significant related to Category 1 issues that would call into question the conclusions in the LR GEIS

- Addresses Category 2 environmental issues during the license renewal term on a site-specific basis 7

Environmental Review 8

How Impacts are Defined

  • SMALL

- Effects are not detectable or are so minor that they will neither destabilize nor noticeably alter any important attribute of the resource

  • MODERATE

- Effects are sufficient to alter noticeably, but not to destabilize, important attributes of the resource

  • LARGE

- Effects are clearly noticeable and are sufficient to destabilize important attributes of the resource 9

How Impacts are Defined (cont.)

- No effect

- May affect but is not likely to adversely affect

- May affect and is likely to adversely affect

  • Essential Fish Habitat (Magnuson-Stevens Act)

- No adverse impacts

- Minimal adverse impacts

- More than minimal, but less than substantial adverse effects

- Substantial adverse impact 10

How Impacts are Defined (cont.)

  • Sanctuary Resources (National Marine Sanctuaries Act)

- No effect

- Not likely to destroy, cause the loss of, or injure sanctuary resources

- Likely to destroy, cause the loss of, or injure sanctuary resources

  • Historic and Cultural Resources (National Historic Preservation Act)

- No adverse effect

- Adverse effect 11

How Impacts are Defined (cont.)

  • Environmental Justice* (Executive Order 12898)

- Disproportionately high and adverse human health and environmental effects

- No disproportionately and adverse human health and environmental effects on minority and low-income populations

  • The NRC chooses to address EJ, though not required. There is a pending vote by the Commission on addressing EJ.

Draft SEIS Preliminary Findings -

Special Status Species and Habitats Under U.S. Fish and Wildlife Service Jurisdiction

  • May affect but is not likely to adversely affect

- California red-legged frog

- California condor

- California least tern

- Hawaiian petrel

- Marbled murrelet

- Short-tailed albatross

- Southern sea otter

  • No effect

- on other federally listed species or critical habitats identified in Section 3.8.4.1 of the draft SEIS 15

Draft SEIS Preliminary Findings -

Special Status Species and Habitats Under National Marine Fisheries Service Jurisdiction May affect and is likely to adversely affect

- Green sea turtle

- Loggerhead sea turtle

- Leatherback sea turtle

- Pacific olive ridley sea turtle May affect but is not likely to adversely affect

- Black abalone

- Gray whale

- Humpback whale May affect but is not likely to destroy or adversely modify

- Critical habitat of the black abalone

- Critical habitat of the humpback whale 16

Draft SEIS Preliminary Findings -

Essential Fish Habitat and Sanctuary Resources

  • Magnuson-Stevens Act: Essential Fish Habitat

- No more than minimal adverse effects on the designated essential fish habitat of all life stages of coastal pelagic species complex, euphasiids (krill), groundfish, and highly migratory species

  • National Marine Sanctuaries Act: Sanctuary Resources

- May affect but is not likely to destroy, cause the loss of, or injure sanctuary resources of the proposed Chumash Heritage National Marine Sanctuary 17

Alternatives

  • No new and significant information identified regarding the following alternatives
  • Alternative energy sources (power replacement)

- Purchased power

- Renewables combination

  • No-action alternative 18

Preliminary Recommendation The adverse environmental impacts of license renewal for Diablo Canyon for an additional 20 years beyond the current expiration date are not so great that preserving the option of license renewal for energy-planning decisionmakers would be unreasonable 19
