Why it Matters

The Commission on Security and Cooperation in Europe — once known as the Helsinki Commission — has scheduled a nuclear power hearing for March 16, 2026, to examine the intersection of nuclear energy and nuclear-armed states through the lens of the ongoing conflict in Ukraine. The briefing arrives weeks after the last remaining nuclear arms treaty between the United States and Russia expired, an event that multiple commission members flagged publicly as a turning point in global security.

The timing and the volume of member activity and lobbying pressure surrounding it suggests the commission sees this as a critical moment to assess how the war has rewritten assumptions about nuclear security Ukraine war planners and policymakers have relied on for decades.

What Sparked This Senate Nuclear Briefing

The most immediate catalyst: on February 5, 2026, the last U.S.-Russia nuclear arms treaty lapsed. Rep. Lloyd Doggett (D-TX-37) was the first commission member to respond publicly, writing that day: "Trump has allowed the last nuclear arms treaty between the United States and Russia to expire today. " Doggett was the most active commission member on hearing-adjacent topics in the weeks leading up to the scheduling. He posted on February 8 that "Putin has lost up to 325,000 soldiers in his illegal war in Ukraine, with few territorial gains to show for it." A day later, he called on Congress to "act to support our Ukrainian partners."

The treaty expiration also drew commentary from Sen. John Fetterman (D-PA), who weighed in on February 6 about nuclear treaties more broadly, writing: "I truly don't see the value in this. The world knows Iran will never honor any treaty."

On the Republican side, Sen. Katie Britt (R-AL) pointed to the administration's actions against Iran's nuclear program on February 2: "With Operation Midnight Hammer, @POTUS sent a message to the world on how important it is to dismantle Iran's nuclear program."

Rep. Robert Aderholt (R-AL-4) focused on the defense supply chain, writing that same day: "The America First agenda can't be accomplished if we are relying on adversaries to make portions of our own weapons."

Sen. Jeanne Shaheen (D-NH) connected the dots to alliance politics on February 13, noting that "support for NATO is at its highest point in history in the United States among voters."

In total, six of the commission's 19 members produced topically relevant public communications in the two weeks before the hearing was announced — a moderate but focused level of engagement that cut across party lines and touched every major dimension of the briefing's subject matter.

Ukraine Nuclear Lessons Draw Heavy Lobbying Interest

The nuclear energy policy landscape around this hearing is crowded with lobbyists. Across the four most recent quarters of disclosure data, at least 15 distinct organizations filed more than 30 lobbying reports on topics directly related to the briefing's focus areas.

Nonproliferation and Threat Reduction

The Nuclear Threat Initiative — a nonprofit dedicated to reducing nuclear and biological threats — registered as a new lobbying client in 2025, filed reports in the second and third quarters, and then terminated its registration in the fourth quarter.

The Council for a Livable World, which advocates for nuclear arms control, reported $40,000 in lobbying expenditures in each of five consecutive quarters from the second quarter of 2024 through the third quarter of 2025, covering nuclear weapons, proliferation, and Ukraine-Russia issues.

Uranium Supply Chain and Russian Fuel Independence

A cluster of companies lobbied aggressively on reducing U.S. dependence on Russian nuclear fuel — a concern that has only intensified as the war grinds on.

Louisiana Energy Services LLC, a subsidiary of uranium enrichment firm URENCO, filed multiple reports in 2025 totaling at least $200,000 in disclosed lobbying on HALEU production and Russian uranium alternatives. U.S. Enrichment Corp. (Centrus Energy) filed reports in the second and third quarters of 2025 on similar topics. Cameco Corp., a major global uranium producer, lobbied on nuclear fuel supply and energy security.

Nuclear Power and Defense Contractors

Day & Zimmermann Group Inc. reported $50,000 per quarter across three quarters on nuclear power and defense topics. Fluor Enterprises Inc. lobbied on small modular reactors and advanced nuclear technology. Southern Co., operator of the Vogtle nuclear plant, filed reports in the second and third quarters of 2025.

Nuclear Technology Exports to Europe

Last Energy Inc. lobbied specifically on micro modular nuclear power plant exports to Europe and potential Department of Defense usage — a direct link between nuclear power Ukraine security concerns and commercial opportunity. The Federation of Electric Power Companies of Japan lobbied to brief Congress on Japanese nuclear energy programs, offering another international comparative lens.

Ukraine-Specific Advocacy

Razom Inc., a Ukrainian-American advocacy organization, reported $10,000 in lobbying in the second quarter of 2024 and filed additional reports through the fourth quarter. VEON Ltd., a telecom company with major Ukraine operations, lobbied on "issues related to the business regarding Ukraine and Russia" across multiple quarters.

The Money Behind the Nuclear Power Ukraine Debate

Several of these lobbying organizations also operate PACs that have contributed to members of Congress.

Southern Company runs four affiliated PACs that have collectively made roughly 1,150 contributions to federal candidates. Fluor PAC has 654 contribution records. Centrus Energy Corp. PAC has made 144 contributions, with notable concentration on Rep. Richard Hudson (R-NC-9) — a Helsinki Commission member — as well as members from states with uranium enrichment facilities. Day & Zimmermann's DAYPAC has 157 contribution records.

The Council for a Livable World's candidate fund, by contrast, has just 13 contribution records — a fraction of the corporate PAC activity, reflecting the asymmetry between industry and advocacy spending in this space.

What to Watch

Several bills in the 119th Congress could be influenced by the hearing's findings:

The bottom line: This briefing sits at the intersection of energy security, nuclear deterrence, and the war in Ukraine — three issues where policy is moving fast and the old frameworks have collapsed along with the last arms treaty. The commission's 19 members, split 10 Republicans to 9 Democrats, will be absorbing information that could shape how Congress approaches nuclear risk in conflict zones for years to come.
