RESUSPENSION OF FISSION PRODUCTS DURING SEVERE ACCIDENTS IN LIGHT WATER REACTORS
Fission product behaviour during core melt-down accidents has been a central part of the risk studies which have been conducted in the USA and the Federal Republic of Germany. According to these studies, the fission products are released from the nuclear fuel to the primary system and the reactor containment in different phases during an accident. Depending on the availability to safety features, some of the airborne fission products enter the environment and cause damage to health and property. These calculations were done using the NAUA code for calculating aerosol behaviour in LWR accidents in order to assess the influence of revolatilization mechanism on the radiological source team. The calculations show that the revolatilization process is clearly a significant component of the radiological source term, but also that the uncertainty is considerable.
