U.S. Pledges $100 Million for Chernobyl Containment Repairs

In February 2025 a Russian drone struck the outer shell of the New Safe Confinement (NSC) that encloses Reactor 4 at the Chornobyl Nuclear Power Plant. The impact created a large breach and compromised the structure’s hermetic seal. The NSC, completed in 2019, was built with €2.1 billion of international funding to contain residual radiation from the 1986 accident and is designed for a 100-year service life.

The United States State Department announced a $100 million contribution, about 20 % of the €500 million repair estimate. Ukraine’s Energy Minister Denys Shmyhal presented the plan at the International Chornobyl Conference. The G7, led by France, is coordinating remaining financing, and the EBRD has earmarked €30 million for damage assessment, design and equipment procurement.

The State Department emphasized “continued leadership on issues of nuclear safety and non-proliferation,” noting the U.S. is “proactively committing 20 %, or $100 million, of the G7’s estimated $500 million cost to rehabilitate the NSC arch and ensure continued safety and security of the Chornobyl reactors and nuclear material.” Shmyhal, in a Telegram post, said the funding discussion involved international partners and highlighted the contribution’s role in “strengthening radiation safety for Ukraine and all of Europe.”

Greenpeace nuclear expert Shaun Burnie warned that the NSC “was a hermetic environment—at least it was before February 14 last year. Now it effectively no longer is,” underscoring the risk of uncontrolled radiation release. The Straits Times noted the pledge arrives “despite Mr Trump’s usual disdain for international assistance,” suggesting political tension over the funding. The State Department’s statement avoided directly attributing blame to Russia for the damage.

Sources differ on currency conversion, reporting the U.S. pledge as $100 million, S$128 million, or $584.95 million (€500 million). No public timeline for completion of the repairs has been disclosed.

The G7 is expected to mobilize additional contributions to meet the €500 million target. Repair work will begin after detailed damage assessments, with continuous monitoring of radiation levels; no increase in background radiation was recorded following the February strike.
