1 Cooper Nuclear Station Annual Assessment Meeting Reactor Oversight Process - 2025 Nuclear Regulatory Commission - Region IV Auburn, Nebraska March 26th, 2026 ADAMS Accession# ML26072A012

2 Purpose of Todays Meeting

• A public forum for discussion of the licensees performance in 2025.

• NRC will address the performance issues identified in the annual assessment letter.

• Licensee will be given the opportunity to respond and inform the NRC of new or existing programs to maintain or improve performance.

3 Agenda

• Introduction

• Review of Reactor Oversight Process

• National Summary of Plant Performance

• Discussion of Plant Performance Results

• NRC Closing Remarks

• Break

• NRC available to address public questions

4 Our Mission The NRC protects public health and safety and advances the nations common defense and security by enabling the safe and secure use and deployment of civilian nuclear energy technologies and radioactive materials through efficient and reliable licensing, oversight, and regulation for the benefit of society and the environment.

Press Release 25-005

5 The NRC Regulates

• Nuclear reactors - commercial power reactors, research and test reactors, new and advanced reactor designs

• Nuclear materials - nuclear reactor fuel, radioactive materials for medical, industrial, and academic use

• Nuclear waste - transportation, storage and disposal of nuclear material and waste, decommissioning of nuclear facilities

• Nuclear security - physical security of nuclear facilities and materials from sabotage or attacks

6 Some Nuclear Facts 94 nuclear power plants supply about 20 percent of the electricity in the U.S.

Nuclear materials are used in medicine for diagnosis and cancer treatment.

Nuclear materials are widely used in industry, such as in density gauges, flow measurement devices, radiography devices, and irradiators.

7 How We Regulate

• Establish rules and regulations.

• Issue licenses.

• Provide oversight through inspection, enforcement, and evaluation of operational experience.

• Conduct research to provide support for regulatory decisions.

• Respond to events and emergencies.

8 Assurance of Plant Safety

• Require defense-in-depth

• Require long-term maintenance of equipment

• Require continual training of operators

• Verify compliance with regulations

9 What We Do - Nuclear Security

• NRC Requires:

- Well-armed and well-trained security forces,

- Surveillance and perimeter patrols,

- State-of-the-art site access equipment and

controls,

- Physical barriers and detection zones, and

- Intrusion detection systems and alarm stations.
