Remote examination, disassembly, and reassembly of grid-type reactor subassemblies at HFEF

;
The use of grid-type subassemblies in EBR-II requires new techniques and equipment for remote interim examination in HFEF. When standard subassemblies are dismantled, the hex tubes are removed and the elements or capsules are slid off the grid bars. When grid-type subassemblies are dismantled, the outer hex tubes are removed; the lower ends of the fuel elements are then released and these elements are gripped and pulled one at a time out of the grid-channel assembly. Several fuel elements can be removed for examination without disturbing the remaining elements.
