Chernobyl repairs need €500M after Russian strike
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
A Russian drone strike damaged the Chernobyl containment arch, and donors have pledged just over half of the €500M repair bill.
The shortfall leaves the steel shelter's ability to contain radioactive waste in question.
Background
The New Safe Confinement is a 36,000-tonne steel arch, completed in 2019, built over the remains of Reactor 4, which exploded in 1986; it was designed to last about 100 years. On the night of Feb. 14, 2025, a Russian drone carrying a high-explosive warhead struck its roof, damaging the structure and starting a fire. The European Bank for Reconstruction and Development (EBRD), a lender set up to fund development in Eastern Europe after the Soviet collapse and a major funder of nuclear safety, has coordinated international Chernobyl safety work since 1995. The funding push comes ahead of the 40th anniversary of the 1986 accident.
How it unfolded
- Feb 14, 2025A Russian drone carrying a high-explosive warhead struck the roof of the New Safe Confinement over the destroyed fourth reactor, damaging the structure and causing a fire.
- Mar 7, 2025Ukraine's State Emergency Service declared the emergency caused by the strike fully resolved, after using thermal-imaging drones to monitor for new fires.
- Dec 2025The International Atomic Energy Agency reported the structure had lost some key safety functions, including its ability to contain radioactive material, though supporting structures and monitoring systems remained intact.
- Apr 2, 2026Chernobyl donors backed plans for possible €500 million in repairs; preliminary assessments by Novarka 2 estimated corrosion of the steel arch threatened long-term safety, with work needed by 2030.
- Apr 27, 2026Ukraine and the EBRD agreed to allocate 30 million euros for the first phase of restoring the protective structure.
- Oct 15, 2026The UK government announced £17 million (€20m) for repairs, part of a broader €30 million engineering and procurement preparation programme.
- Oct 2026G7 countries pledged €260 million, just over half the estimated cost, and urged other countries to contribute.
- Nov 9, 2026A fundraising conference in Paris, co-chaired by France, Ukraine and the EBRD, is intended to draw further pledges.

Who’s saying what
- Official
- EBRD President Odile Renaud-Basso says there is no immediate danger, but the damage must be repaired before 2030 or moisture could cause corrosion beneath the arch and make radioactive waste management far harder and costlier.
- Official
- Renaud-Basso argues the problem is global: "It's not a Ukrainian problem. Everybody should feel concerned about nuclear safety globally."
- Caution
- Renaud-Basso says securing the remaining money "is going to be a challenge" and the Paris conference might not produce all commitments immediately; she does not expect Russia to contribute directly.
Still unverified
The EBRD's roughly €500 million repair estimate is preliminary, with technical assessments continuing. The IAEA confirmed explosions at the plant but did not mention Russia in its statement.
