Abstract
Monitoring of VVER fuel assemblies condition in Slovakia is presented in the paper. The Slovak wet interim spent fuel storage facility in NPP Jaslovske Bohunice was build and put in operation in 1986. Since 1999, leak tests of VVER-440 fuel assemblies are provided by special leak tightness detection system "Sipping in Pool" delivered by Framatome-anp facility with external heating for the precise detection of active specimens. Although this system seems to be very effective, the detection time of all fuel assemblies in one storage pool is too long (several months). Therefore, a new "on-line" detection system, based on new sorbent NIFSIL for effective ^<134>Cs and ^<137>Cs activity was developed. The design of this detection system and its possible application in the Slovak wet spent fuel storage facility is discussed in this paper. For completeness, the initial results of the new system are also presented.
