[en] At the end of 1987, the work for preparing the safe enclosure of the reactor was completed, and on March 22, 1988 the supervisory authority gave permission to start operational activities for post-shutdown containment of the reactor, as of March 30, 1988. The personnel of KWL was reduced to 12 members in the reporting year. As financial reserves for decontamination and waste management, DM 14.6 millions were required, and DM 3.6 millions for reprocessing. The annual loss of DM 20.3 millions was compensated by VEW by mena of supplementary contributions. KWL also, as in previous years, contributed in 1987 to research projects of the European Commission (Euratom), the KWL programme covering the field of containment after decommissioning, and theoretical and experimental studies on the effects of ventilation and air-drying on activity release and corrosion in the plant.
