Patent GB-1221522-A (GB)
Title: Improvements relating to nuclear reactor fuel elements
Inventor: CAMPBELL RONALD HUGH
IPC: G21C3/04
Filed: 1967-05-16
Abstract: 1,221,522. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 3 May, 1968 [16 May, 1967; 15 June, 1967], Nos. 22767/67 and 27628/67. Addition to 1,107,384. Heading G6C. A fuel element has a passage-defining component disposed within its sheath and arranged so as to form by means of its exterior surface an additional passage in series with that defined by the component, the two passages providing a vent path along which gaseous fission products are constrained to flow before leaving the interior of the sheath. Alternatively, or in addition, tubing is provided which at least in part extends over an external surface of the sheath, this tubing serving to convey gaseous fission products from the interior of the sheath to a remote position for discharge to the reactor coolant. Fig. 3 illustrates the combination of two different features of the invention, either of which can be employed separately if desired. A tubular fuel pin 30 for a sodium-cooled fast reactor has fuel pellets 34 stacked in the annular space 33 between outer and inner tubular sheaths 31, 32 with a perforated platform 35 secured to one of the sheaths separating the fuel from a fission product gas plenum 36. One of the features is the provision in the plenum 36 of a doublycoiled capillary tube 44. One end 45 of the tube 44 is an interference fit in a bore 41 of an annular member 37 welded to the lower end of the outer sheath 31 at 38 with its bore 39 accommodating the inner sheath 32 with clearance. From thence the tube 44 forms a first set of close-fitting coils 46, changing direction near the top of the plenum 36 to form a second set of close-fitting coils 47 fitting snugly on the coils 46. Fission product gases from the fuel 34 flow in an extended path over the exterior of the coils 46, 47, the path being serpentine as a result of the close packing of the coils, and then enter the open end 48 of the tube 44 and traverse the double helical path provided by the coils 47, 46, leaving the tube 44 at the end 45 in the bore 41. The other feature is the provision of a capillary tube 43 which is connected to the bore 41 and is coiled upwardly around the exterior of the outer sheath 31 and at its open upper end terminates at the upper end of the fuel pin (not shown) to provide an outlet for the fission product gases. The tube 43 not only provides an extended flow path but also serves as a fin or rib on the outer sheath to assist in heat removal by promoting coolant turbulence as well as spacing the fuel pin from adjacent fuel pins in a clustertype fuel assembly.
