Updated on Nov. 8, 2026 in People
The NNSA named Betty L. Huck manager of its Savannah River Field Office, announcing the appointment on Nov. 2. Huck replaces Michael A. Mikolanis, who was named manager of the NNSA Los Alamos Field Office in August.
Why it matters
The Savannah River Field Office oversees the federal landlord role for the 310-square-mile Savannah River Site in South Carolina. Leadership at the field office shapes oversight of national security and nonproliferation work at a major federal facility in the state.
The field office oversees an annual contract budget of more than $2.9 billion and a contract workforce of more than 5,000 people across the 310-square-mile Savannah River Site. The source does not address how the budget or workforce may change under Huck's leadership.
The players
National Nuclear Security Administration (NNSA)
The NNSA is a semi-autonomous agency within the U.S. Department of Energy responsible for maintaining the nation's nuclear weapons stockpile and advancing nonproliferation efforts.
Betty L. Huck
Betty L. Huck is a federal official who previously managed the NNSA Nevada Field Office and brings about 15 years of prior DoD and intelligence support service to her new role.
Michael A. Mikolanis
Michael A. Mikolanis is a federal nuclear official who led the Savannah River Field Office from March 2024 before being named manager of the NNSA Los Alamos Field Office.
The details
Huck is responsible for implementing national security and nonproliferation missions, including oversight of program management, nuclear operations, security, quality assurance, environment, safety and health, and key mission deliverables. She previously served as manager of the NNSA Nevada Field Office at the Nevada National Security Sites and has held multiple NNSA leadership positions overseeing high-hazard and nuclear operations.
Timeline
March 2024: Mikolanis began managing the Savannah River Field Office.
August 2021 to March 2024: Mikolanis managed the Environmental Management Los Alamos Field Office.
August: Mikolanis was named manager of the NNSA Los Alamos Field Office.
Nov. 2: The NNSA announced Huck's appointment to Savannah River.
Leadership Continuity
The move follows the NNSA's practice of shifting experienced field managers among its sites, as Mikolanis moved from Savannah River to Los Alamos in the same year. Huck's Nevada field leadership carries directly into oversight of the Savannah River Site.
The appointment changes who directs federal oversight of the Savannah River Site but does not alter day-to-day services or contracts for residents. Workers and contractors at the site will continue under existing oversight structures.
The takeaway
Leadership changes at federal nuclear sites can shift oversight priorities even when day-to-day operations continue steadily. Following who runs these field offices helps explain how national security programs are managed in practice.
