This paper presents the activity in preparing the decommissioning plan for the VVR-S research reactor taking into account that there is no experience in this field in Hungary. VVR-S IPNE reactor, situated in Magurele Village, near Bucharest, was put into operation on the 27th of July 1957 and it has continuously been operating without major events, up to now. During this period, no modifications concerning the core and main circuits were made. The reactor is still operating with the original equipment and control instrumentation supplied by Ex-Soviets Union. The reactor was designed and built at the scientific and technological level of the 50`s. VVR-S IPNE reactor is a thermal one, of 2 MW nominal power and tank-type. It is light water cooled and moderated. The core operates with EK-10 type fuel assemblies (made of UO{sub 2} - MgO, with 10% U{sup 235} enrichment); after 1984 a mixed core with EK-10 and S-36 type assemblies was employed. The present fuel stock is S-36 type (36.6% U{sup 235} enrichment).
