Politicians in the southern Dutch provinces of Zeeland and Brabant are extremely concerned about conditions in the Belgian nuclear power station in Doel, the Volkskrant said on Wednesday.

Reports of leaks, cracks, poor monitoring and even sabotage have led them to raise the issue with the provincial authorities.

One of the four reactors has been closed since the beginning of this month because of an oil leak, which may have been the result of sabotage, the Volkskrant said.

The Doel power station is on the Westerschelde estuary, close to Antwerp. Two of the four reactors are not currently in service.

The Netherlands has one nuclear power station at Borssele, in Zeeland province.
