As one observation of interest to the technical staff, while waiting to return the source to the LSI, the source remained in the shielded cask within the two nylon support hoses. After the source s return to the LSI, it was discovered that the nylon support hose had significantly deteriorated with small holes and weakened threads evident in the immediate vicinity of the source location. A longer delay in returning the source could have possibly resulted in the nylon hoses becoming unable to contain the source. Plastic prongs were for depth determination.
