Abstract

The ability to disassemble an irradiated Fast Flux Test Facility (FFTF) Driver Fuel Assembly (DFA) is important both to the continued operation of the FFTF and the future of the Breeder Reactor Program. At the FFTF, DFA's with up to three (3)* kilowatts of decay heat will be placed in the Interim Examination and Maintenance (IEM) Cell for disassembly and nondestructive examination. This process includes sodium removal, duct measurement, duct cutting and pulling, fuel pin removal, and component disposition to other laboratories for destructive examination.

FFTF/IEM (Fast Flux Test Facility/Interim Examination and Maintenance) cell fuel pin removal equipment

Conference Greenwell, R - Transactions of the American Nuclear Society; (USA)

This paper describes a fuel pin removal device used for pin removal from irradiated fuel assemblies at the Fast Flux Test Facility (FFTF). After irradiation in the FFTF, selected fuel assemblies are remotely disassembled in the Interim Examination and Maintenance (IEM) cell. The remote disassembly, following sodium removal, consists of slitting and removing the duct and then removing the fuel pins one-at-a-time by sliding the pins from parallel attachment rails. All pins are removed from one rail before starting on the next. The new pin removal equipment has been used very successfully on the last three fuel experiments disassembled inmore »« less

Subassembly duct cutting in the FFTF/IEM cell

Conference Gibbons, P - Trans. Am. Nucl. Soc.; (United States)

After irradiation in the Fast Flux Test Facility (FFTF), certain driver fuel assemblies (DFA) are selected for disassembly in the interim examination and maintenance (IEM) cell for further examination elsewhere. Cutting operations near fuel pins are delicate evolutions, and inadvertent penetrations of pin claddings have occurred. Improved features related to precise and reliable position control that have been incorporated into the FFTF cutters are described. The IEM cell cutters have proven to be effective tools in DFA processing.
FAILED FUEL DISPOSITION STUDY

Technical Report THIELGES, J.

In May 2004 alpha contamination was found on the lid of the pre-filter housing in the Sodium Removal Ion Exchange System during routine filter change. Subsequent investigation determined that the alpha contamination likely came from a fuel pin(s) contained in an Ident-69 (ID-69) type pin storage container serial number 9 (ID-69-9) that was washed in the Sodium Removal System (SRS) in January 2004. Because all evidence indicated that the wash water interacted with the fuel, this ID49 is designated as containing a failed fuel pin with gross cladding defect and was set aside in the Interim Examination and Maintenance (IEM)more »« less

Material open test assembly processing at the FFTF's IEM cell. [Interim examination and maintenance]

Conference Danko, A

The Interim Examination and Maintenance (IEM) Cell is a vertical hot cell located within the containment dome of the Fast Flux Test Facility (FFTF). The cell has two basic functions: (1) to perform disassembly/reassembly and nondestructive testing on radioactive, sodium-wetted reactor components, and (2) to provide a shielded work volume where radioactive, sodium-wetted reactor and refueling equipment can be repaired and maintained. One of the recent FFTF experiments processed through the IEM Cell was the Material Open Test Assembly (MOTA). This paper describes the disassembly and reassembly of the MOTA test assembly.
