    HšQQHThe present application relates generally to nuclear filel rods; and moreparticularly to, a system for assembling or disassembling a segmented rod of a nuclear fuel bundle used within a nuclear reactor pressure Vessel. ' ~§$~4ifl>šš§§~Figure 1 is a schematic illustrating an environment in which an embodiment of thepresent inVention may operate. Figure 1 illustrates a typical nuclear processing facility , which may comprise a spent filel pool 12, and a reactor pressure Vessel (RPV) 15. 2 is a schematic illustrating the RPV 15 of Figure 1. During operation ofthe reactor, cooling water circulating inside a RPV 15 is heated by nuclear fissionproduced in the nuclear fuel core 35. Feedwater is admitted into the RPV 15 Via afeedwater inlet 17 and a feedwater sparger 20. The feedwater flows downwardly througha downcomer annulus 25, which is an annular region between RPV 15 and a core shroud . core shroud 30 is a stainless steel cylinder that surrounds the nuclear fuel core35, which includes nuclear fuel bundle assemblies 40, only a few are illustrated in Figure2, having a plurality of segmented fuel rods 43. A top guide 45 and a core plate 50support each fuel bundle assembly 40. §5The cooling water flows downward through the downcomer annulus 25 and intothe core lower plenum 55. Then, the water in the core lower plenum 55 flows upwardthrough the nuclear fuel core 35. In particular, water enters the fuel bundle assemblies40, wherein a boiling boundary layer is established. A mixture of water and steam exitsthe nuclear filel core 35 and enters the core upper plenum 60 under the shroud head 65.The steam-water mixture then flows through steam separators 70 on top of the shroud head 65 and enters the steam dryers 75, which separate water from steam. The separated 232414 water is recirculated back to the downcomer annulus 25 and the steam flows out of the RPV 15 and to a steam turbine, or the like, which is not illustrated in the Figures. .ffïïl-fgThe BWR also includes a coolant recirculation system, which provides the forcedconVection flow through the nuclear fuel core 35 necessary to attain the required powerdensity. A portion of the water is drawn from the lower end of the downcomer annulus25 Via recirculation water outlet 80 and forced by a recirculation pump (not illustrated)into a plurality of jet pump assemblies 85 Via recirculation water inlets 90. The jet pumpassemblies 85 are typically circumferentially distributed around the core shroud 30 andprovide the required reactor core flow. A typical BWR may haVe between sixteen to twenty-four inlet mixers 95. .fiï-*fgAs illustrated in Figure 2, a conventional j et pump assembly 85 comprises a pair ofinlet mixers 95. Each inlet mixer 95 has an elbow welded thereto, which receiVespressurized driVing water from a recirculation pump Via an inlet riser 97. A type of inletmixer 95 comprises a set of f1Ve nozzles circumferentially distributed at equal anglesabout an axis of the inlet mixer 95. Here, each nozzle is tapered radially inwardly at thenozzle outlet. This convergent nozzle energizes the j et pump assembly 85. A secondaryinlet opening may be located radially outside of the nozzle exits. Therefore, as ets ofwater exit the nozzles, water from the downcomer annulus 25 is drawn into the inletmixer 95 Via the secondary inlet opening, where mixing with water from the recirculation pump then occurs. ï šéš-fëDuring the shutdown of the nuclear reactor, some of the segmented rods 43 may be remoVed from a fuel bundle assembly 40. These segmented rods 43 are thendisassembled for further processing. The disassembly process is time consuming,delaying the processing and preparation of the segmented rods 43 before reentry into the RPV 15. the aforementioned reasons, there is a need for a system for disassembling a plurality of segmented rods 43 of a nuclear reactor core. The system should allow for 232414 simultaneously disassembling multiple segmented rods 43. The system should reduce the disassembly time and lower operator exposure to radioactivity.
