After 50 years of operation, Unit 1 at Belgium’s Doel nuclear power plant has been permanently shut down.

Just weeks ago, Belgian Prime Minister Bart de Wever talked about trying to keep Doel-1, which was retired on February 14, in operation. He faced an uphill battle, however, given the decades the nation has spent arguing about nuclear energy. In 2003, Belgium enacted a law banning construction of new nuclear reactors and calling for eventual decommissioning of existing reactors, Belga News Agency reported.

The Belgian government has signed a nonbinding letter of intent with Electrabel, a subsidiary of the French utility Engie, to keep nuclear a part of Belgium’s energy mix for an additional 10 years.

Electrabel operates Belgium’s two nuclear power plants, the four-unit Doel and three-unit Tihange.

In a move motivated by Russia’s invasion of Ukraine and the sky-high energy prices hitting Europe as a result, the Belgian government last Friday announced its intention to extend the operational life of two of its nuclear power reactors, Doel-4 and Tihange-3, through 2035.

Framatome’s digital instrumentation and control (I&C) systems at the Doel nuclear power plant in Belgium have passed the final site acceptance test, the company announced on June 11. The news marks the completion of the project to modernize the control and emergency systems of Units 1 and 2, both of which entered commercial operation in 1975.
