Belgium’s oldest nuclear reactor shut down for good after 50 years

The Doel 1 nuclear reactor was definitively shut down safely on Friday night, the Federal Agency for Nuclear Control (FANC) has confirmed. After 50 years of electricity production, Belgium’s oldest nuclear reactor, with a capacity of 445 megawatts, was disconnected from the high-voltage grid at 21.37.

The FANC said the operation was carried out in complete safety. “Technically, there is no difference from a temporary maintenance shutdown, except that the reactor will not be restarted to produce electricity,” it said in a press release.

A shutdown phase lasting approximately five years is now beginning, during which the fuel will be cooled in order to “significantly reduce the radiological risk to the environment”. The waste will also be removed and the pipes emptied and rinsed. Then the actual dismantling will begin, which could last up to 15 more years.

Lifespan extended

Doel 1 is the third reactor to be definitively decommissioned, after Doel 3 in 2022 and Tihange 2 in 2023. Tihange 1 will also be shut down in the autumn.

The shutdown phase for Doel 1 will be slightly different to that for the other reactors, as Doel 1 and 2 are “twin” reactors that share certain systems, such as the control room and the engine room. These parts will only be shut down when Doel 2 is definitively decommissioned on 30 November.

Belgium will then have only two active nuclear reactors: Doel 4 and Tihange 3. Their operating period has been extended by 10 years until 2035 and the new federal government hopes to extend them for another decade.
