Consequences of the absence of negative pressure in the containment of the nuclear power plant at Lingen
After nine years of operation, the KWL nuclear power plant was shut down and brought to a state of Safe Enclosure (SE). In this paper, the main features of the SE and its behaviour in the first two years of operation are reported. This project mainly involved the evaluation of the controlled and uncontrolled air exchange with the atmosphere and the airborne activity release. Measurements were performed with a small off-air system and the air exchange without negative pressure in the SE was calculated. The activity release itself was found to be very small and so was the difference between the figures with and without negative pressure. Therefore, operation of the SE without negative pressure is acceptable.
