Death by a Thousand Cuts: How Messy Preemption Doctrine Has Allowed States to Veto Nuclear Development

The United States is entering a renewed period of interest in nuclear energy driven by necessity. Explosive growth in energy-intensive industries, most notably data centers, advanced manufacturing, and artificial-intelligence infrastructure, has revived demand for reliable, carbon-free baseload power at a scale intermittent renewable resources cannot yet supply. Nuclear energy uniquely satisfies these demands, and policymakers who once treated nuclear expansion as politically untenable now increasingly view it as essential to economic competitiveness, industrial policy, and grid reliability. Yet this renewed enthusiasm confronts a structural obstacle with deep historical roots: the persistence of effective state veto power over nuclear development in a regulatory field Congress designed to be predominantly federal. The extent of this veto power is largely due to confused judicial doctrine. Although the Atomic Energy Act assigns exclusive federal responsibility over radiological safety and reactor licensing, early Supreme Court decisions tolerated state interference so long as states characterized their regulations as grounded in economics, or other non-safety concerns. The framework announced in Pacific Gas & Electric Co. v. State Energy Resources Conservation & Development Commission allowed courts to defer to asserted legislative purposes rather than examine practical regulatory consequences. Over time, that approach enabled states to obstruct federally licensed projects through moratoria, emergency-planning requirements, and economic regulation that functioned as de facto safety regulation. The resulting uncertainty undermined investment, extended construction timelines, outright left completed nuclear plants abandoned, and contributed materially to the collapse of new nuclear deployment in the United States. This Article argues that modern preemption doctrine now provides an opportunity to correct that departure from congressional design. The fractured decision in Virginia Uranium, Inc. v. Warren reveals an emerging consensus that preemption analysis must begin with the Atomic Energy Act’s jurisdictional structure rather than speculative inquiries into legislative motive. Building on that insight, this Article proposes a unified framework that combines statutory allocation of authority under Section 2021 with an objective effects-based inquiry drawn from English v. General Electric. Under this approach, state laws are categorically preempted when they intrude upon nondelegable areas of NRC authority, conditionally permissible where Congress expressly preserved state participation, and subject to implied preemption when they directly and substantially interfere with federally regulated nuclear safety decisions. By restoring the line Congress intended between federal supremacy and legitimate state governance, this framework reduces opportunistic state obstruction, restores regulatory predictability, and aligns preemption doctrine with the economic realities necessary for a durable American nuclear revival.
