Abstract

The U.S. Nuclear Regulatory Commission (NRC) prepared this supplemental environmental impact statement (SEIS) in response to Vistra Operations Company, LLC and Luminant’s application to renew the operating license for Comanche Peak Nuclear Power Plant (Comanche Peak), Units 1 and 2 for an additional 20 years. Luminant is a subsidiary of Vistra Operations Company, LLC. This SEIS evaluates the environmental impacts of the proposed action and alternatives to the proposed action. Alternatives considered include: (1) New Nuclear (Small Modular Reactors), (2) Natural Gas-fired Combined-Cycle, (3) Combination Solar Photovoltaic, Onshore Wind, and New Nuclear, and (4) no renewal of the operating licenses (the no-action alternative). The NRC staff’s recommendation is that the adverse environmental impacts of license renewal (LR) for Comanche Peak are not so great that preserving the option of LR for energy-planning decisionmakers would be unreasonable. The NRC staff based its recommendation on the following factors:

• the analysis and findings in NUREG-1437, Generic Environmental Impact Statement for License Renewal of Nuclear Plants
• the environmental report submitted by the applicant, as supplemented
• the NRC staff’s consultation with Federal, State, Tribal, and local agencies
• independent environmental review
• the consideration of public comments
