S-4495-119
Read twice and referred to the Committee on Armed Services.
What it does
This bill would require the Secretary of Defense and the Under Secretary of Energy for Nuclear Security to jointly submit a report to Congress within 120 days of enactment. The report would assess dangers posed by nuclear reactors — existing or planned within 10 years — located in regions that have experienced armed conflict in the past 25 years or are likely to experience conflict in the future, including areas near Ukraine, the Middle East, Eastern Europe, South Asia, Taiwan, and the Korean Peninsula. The report would also identify steps the U.S. and its allies could take to prevent, prepare for, and mitigate those risks. The report must be submitted in unclassified form but may include a classified annex.
Who benefits
Members of Congress and relevant committees (Armed Services, Foreign Relations, Energy and Commerce) who would receive actionable intelligence on nuclear safety risks. U.S. allies and partners near conflict-zone reactors, particularly in Eastern Europe and East Asia. Civilian populations living near nuclear facilities in contested regions, such as those near the Zaporizhzhia plant in Ukraine. U.S. national security planners and military strategists who would gain a formal assessment of reactor-related risks. Nonproliferation and nuclear safety advocacy organizations that would benefit from a public unclassified report. Journalists and researchers studying nuclear security.
Who is hurt
No group faces direct material harm from a reporting requirement. However, the bill could indirectly create diplomatic friction with countries whose nuclear programs are named — including Russia, China, India, Pakistan, North Korea, and Iran — if the unclassified report is perceived as adversarial. Countries hosting reactors in the named regions may view the assessment as interference in their energy or defense policy. Federal agency staff at the Department of Defense and Department of Energy would bear the administrative burden of producing the report within 120 days.
Supporters argue
Supporters argue that the Zaporizhzhia nuclear power plant — the largest in Europe — has been repeatedly shelled and occupied during the Russia-Ukraine conflict, creating documented radiation risks that the international community was unprepared to manage. They contend that a formal, government-wide assessment is a minimal and prudent step to ensure the U.S. military and its allies have a coordinated plan for reactor-related contingencies in future conflicts, particularly as new reactors are being built in contested regions. Given that nuclear accidents can affect populations across national borders, supporters argue the report serves both national security and humanitarian interests at negligible cost.
Opponents argue
Opponents argue that the bill duplicates work already performed by existing intelligence and defense agencies, including the Defense Intelligence Agency and the Department of Energy's National Nuclear Security Administration, and that mandating a new report within 120 days strains agency resources without guaranteeing actionable policy outcomes. They contend that publicly naming specific conflict scenarios — such as a Chinese attack on Taiwan or a Russian attack on NATO members — in statute could complicate diplomatic relationships and signal U.S. threat assessments in ways that are better handled through classified channels, potentially undermining the very security interests the bill aims to protect.
