Vandellòs I nuclear incident: Introduction

The fire started where nobody wanted a fire in a nuclear plant: in the turbine hall. On the night of 19 October 1989, a mechanical failure in the steam turbine of the Vandellòs I Nuclear Power Plant ignited a blaze on the Catalan coast, and the flames found cabling that was never made to resist them. As the fire spread, it began knocking out the very systems meant to keep the reactor safe, including the control computer and part of the cooling system. What happened over the following hours would be remembered as one of the most serious nuclear accidents in Western Europe, and as a near miss that only human nerve prevented from becoming far worse.

Vandellòs I was a product of its era, and that era was the tail end of Francoist Spain. France sold Spain a UNGG reactor, a gas-and-graphite design that was already obsolete by the time it was installed. Its appeal was not efficiency. As a by-product, this kind of reactor yielded...

Seventeen years after the plant opened, that cascade arrived. The failure in the steam turbine was mechanical and ordinary in isolation, the sort of breakdown that happens in power stations of every kind. Here it lit a fire, and the fire exposed how thin the margins really were. ...

A core meltdown was avoided, and it was avoided by people. The Corps of Firefighters of Catalonia fought the blaze alongside the plant's own technicians, and together they managed to put the fire out and shut the reactor down manually, overriding the automated systems that the fl...

Vandellòs I nuclear incident: A Place in a Grim Catalogue

Mon, 20 Jul 2026 00:00:00 GMT

Vandellòs I earned a permanent entry in the short, sobering catalogue of Western Europe's most serious civil nuclear accidents. It is studied alongside the great cautionary tales of the atomic age, from the Windscale fire in Britain to Three Mile Island in the United States, as a...

The reactor never ran again. The damage to its systems was severe enough that the plant was decommissioned, its working life ended not by age alone but by the night the turbine burned. Classified as a serious incident on the International Nuclear Event Scale, Vandellòs I forced a...
