Reactor safety research activities in Yugoslavia

At this time Yugoslavia has one 632 MWe nuclear power plant of PWR design, located at Krsko. NPP Krsko, which is a two-loop plant, started power operation in 1981. In 1986 the Krsko Nuclear Power Plant produced 3824.5 GWh electric power which is 1.2% above the planned production. Generator on-line operation was 6561 hrs. By May 1987 the NPP Krsko has supplied 20 billion KWh to the grid. Preparatory activities are continuing for the planned series of nuclear power plants to be built up to the year 2000. In connection with this Yugoslav Association of Electric Utilities (JUGEL) has ordered a study to determine the basis for safety criteria to be used for these nuclear power plants. The ''Jozef Stefan'' Institute has coordinated the effort in which several Yugoslav institutions took part and the resulting final report was published in 1986. Particular attention in the past year was placed to the development of regulations covering nuclear safety requirements for the future plants. New federal regulations on criteria for siting, design, commissioning, operation and decommissioning, on safety analyses reports, on requirements for operating personnel and on safeguards were drafted and are expected to be passed later this year
