Experience in mothballing Zwntendorf

Mothballing the nearly complete nuclear power station of Zwentendorf proceeds on the basis of a preservation concept first drafted in late 1978 by the manufacturer of the plant, Kraftwerk Union (KWU) and later revised in some respects. Executing the work was the responsibility of the operator and the firms commissioned by him, respectively, which again primarily include KWU. The nuclear power plant is now mothballed in a way preserving its value and its standards; the preservation status is regularly checked by experts. Commissioning activities therefore could be started at any time with a minimum of losses in plant substance. (orig.)
