An failed fuel detection and location system (FFDL) using a sipping method is adopted as the FFDL of Joyo. FFDL has not operated since the first falled fuel simulated (FFDL-I) test in April, 1985 because Joyo has not yet experienced any operation with breached fuels. Therefore, the operational test (II) of FFDL was carried out on July 12
19, 1991 for a preparation of the FFDL-II test which is scheduled in 1992. Main results from the test are as follows ; (1)The adequacy of the functions and operating procedure of FFDL was reaffirmed and the operating experience was gained. (2)Radioactivity measurement was conducted by FFDL for six subassemblies and their integrity was confirmed.

This report describes the operational experience during the MK-II core and a theme of the future Fuel Cleaning Facility in "JOYO". Following results are obtained. (1)The sodium guantity adhered the spent core elements is influenced by the inner structure of the elements. (2)The corrosion product guantity in the washing waste water is mainly influenced by the corrosion product adhering to material surface. (3)The sodium guantity in the water which is contained in a can differs from the kind of elements. (Maximum value of sodium is about 8 grams) (4)During the washing by demineralized water, reaction velocity and guantity of sodium which adheres to a element differ from the kind of elements. Therefore, it is necessary to establish the washing way depend on the elements.
