Vice President, Production and Operations

Gene Sievers is the vice president of Production and Operations for Consolidated Nuclear Security, the management and operating contractor for the Y‑12 National Security Complex in Oak Ridge, Tennessee. Sievers is responsible for overseeing Production; Operations Support; and Safeguards, Security, and Emergency Services. Prior to this role, he served as Y‑12 site manager, where he led daily operations to sustain a safe, secure, and effective nuclear deterrent.

Before being appointed Y‑12 site manager, Sievers served as vice president of Mission Assurance for CNS. In this role, he was responsible for several organizations, including Enterprise Occupational Health; Operations Assurance; Quality; and Environment, Safety, and Health. As the nation responded to the COVID‑19 pandemic, Sievers led the Mission Assurance organization to ensure the work environment was responding proactively to its employees, the public, and the environment. During that time, Sievers ensured that the quality of production activities met requirements of federal program and design agency customers, which provided certifiable confidence in the nuclear stockpile. Other daily responsibilities included providing subject matter expertise for all readiness activities
as well as nuclear and explosives safety and coordinating with the Department of Energy Office of Enforcement Coordination.

Sievers began his Y‑12 career in Nuclear Safety Operations in 2013, providing oversight for Disciplined Operations. He led the Y‑12 Protective Force through a contract transition and a highly successful Enterprise Assessment Inspection. During his Y‑12 tenure, he served as the deputy site manager and provided leadership for day‑to‑day operation of the Y‑12 site before assuming the role of senior director of Y‑12 Environment, Safety, and Health. Sievers also served as CNS’s acting president and chief executive officer for approximately 6 weeks in 2022.

Sievers began his service to the nation with 27 years in the U.S. Navy, where he served on four nuclear submarines supporting the national security strategy in both the Atlantic and Pacific theaters of operation. His military service culminated in command of USS Columbia (SSN 771) and Submarine Squadron 6.

He holds an M.B.A. from the Florida Institute of Technology and a B.S. in mechanical engineering from West Virginia University.
