Senator Mike Lee (R-UT), Chairman of the Senate Energy and Natural Resources Committee, and Sen. Dave McCormick (R-PA) introduced the Nuclear Energy Innovation and Deployment Act (NEIDA) on April 14, 2026—directly targeting the infamous “Valley of Death” that has stalled advanced nuclear developers for years.

Advanced nuclear technologies—small modular reactors (SMRs), microreactors, high-temperature gas reactors, and other next-gen designs—have cleared lab and early demonstration hurdles.

The killer gap is moving from “first-of-a-kind” demo to commercial deployment:

• Multi-year NRC licensing delays and uncertainty scare off private capital.
• Overlapping federal rules, high compliance costs, and risk-averse investors create a financial no-man’s-land.
• Result: U.S. developers tread water while China and Russia rapidly build, export, and dominate the global nuclear supply chain.

Electricity demand is exploding from AI data centers, manufacturing revival, EVs, and electrification—yet the U.S. has been stuck in neutral on the one technology that delivers dense, firm, 24/7 power at scale.

The bill is surgical, not a blank check:

• Clarifies and expands DOE authority over nuclear facilities and materials—especially demonstration and test reactors conducted under DOE contracts (including privately funded ones). This shifts key oversight for experimental projects away from the slower, more prescriptive NRC process.
• Directs the NRC to update regulations that currently conflict with or limit DOE’s existing statutory role.
• Creates a “Nuclear Energy Launch Pad”—designated federal and non-federal sites for streamlined testing and demonstration under DOE leadership.
• Establishes clear pathways for commercial reactors and fuel-cycle facilities on federal land or for federal purposes.
• Supports Power Marketing Administrations in backing nuclear via purchase agreements and explores using surplus plutonium as fuel.

Quote from the one-pager: “Despite significant technological progress, advanced nuclear developers face a persistent ‘valley of death’ between demonstration and commercial deployment—at precisely the moment when rapid deployment is most needed.”

Sen. Lee: “Electricity demand is rising at a pace we haven’t seen in generations… The biggest obstacle is our inability to build. To meet demand, we must accelerate the development of nuclear energy by removing regulatory barriers, unlocking federal resources, and creating a path from demonstration to deployment.”

This Is a Big Deal

Nuclear’s physics advantages are unmatched: ~90%+ capacity factor, minimal land footprint, zero weather dependence, and the highest energy density of any source. It’s the only proven way to deliver reliable, high-output power while keeping emissions low—exactly what surging demand requires.

Past U.S. nuclear progress has been strangled by post-1970s regulatory ratcheting, endless litigation, and a “design-as-you-go” approach for novel reactors. NEIDA doesn’t weaken safety—it makes regulation smarter and risk-informed, tailored to demonstration vs. commercial phases. DOE already safely oversees national labs and test reactors; this just removes duplicative hurdles that have produced paralysis without added safety gains.

Nuclear developers and industry groups have already applauded the bill. It aligns with the current administration’s executive push on advanced reactors, HALEU fuel, and workforce development.

EXCLUSIVE: Mike Lee Takes On ‘Valley Of Death’ Plaguing Nuclear Energy Developers

Republican Utah Sen. Mike Lee is introducing legislation seeking to remove regulations plaguing nuclear energy developers and help the U.S. compete with adversaries in harnessing the power source.

The Daily Caller das the story.

Lee’s Nuclear Energy Innovation and Deployment Act (NEIDA) “modernizes and clarifies” the ability of the Department of Energy (DOE) over nuclear power facilities and aims to speed up the commercialization of the energy source, according to a one-page summary of the bill shared with the Daily Caller News Foundation.

The one-pager notes that the need for “flexible pathways” for nuclear energy deployment and commercialization is becoming “increasingly urgent” due to China and Russia’s efforts to outpace the U.S. in nuclear power production, as well as anticipated skyrocketing energy demand partly driven by the artificial intelligence (AI) boom.

Republican Pennsylvania Sen. Dave McCormick is cosponsoring the legislation introduced Tuesday.

“Electricity demand is rising at a pace we haven’t seen in generations. We can meet that demand, or we can fall behind,” Lee, the chair of the Senate Energy Committee, told the Daily Caller News Foundation in a statement. “The biggest obstacle is our inability to build.”

“To meet demand, we must accelerate the development of nuclear energy by removing regulatory barriers, unlocking federal resources, and creating a path from demonstration to deployment,” the senator added.

“Other countries are already preparing their grids for the next generation of technologies. The United States should be doing the same.”

“Pennsylvania is powering America’s future, and surging electricity demand requires reliable energy,” McCormick said in a statement to the DCNF. “The Nuclear Energy Innovation and Deployment Act will remove regulatory barriers, accelerate next-generation nuclear deployment, and ensure the United States—not China or Russia—leads the global nuclear renaissance.”

“This means affordable baseload power for consumers, stronger energy security for our nation, and real American energy dominance,” the senator added.
