A theme park spokesperson said: "In the autumn of 1972, The Netherlands, Belgium and Germany decided to cooperate in the common construction of the Schneller-Bruter Nuclear Plant but because of political reasons it was decided in 1991 never to use this nuclear power station. Since this power station has never been put into use, this whole complex is guaranteed free of radiation." Caters News Agency
