Patent GB-1454618-A (GB)
Title: Nuclear fuel element
IPC: G21C3/16
Filed: 1974-01-30
Abstract: 1454618 Fuel elements ATOMENERGI AB 30 Jan 1974 [2 Feb 1973] 04389/74 Heading G6C A fuel element for use in a nuclear power reactor comprises a plurality of ceramic fuel pellets 3 housed within a cylindrical cladding tube 1 provided on its inner surface with at least eight longitudinal ribs 5, a cold assembly gap of at least the radial extent of a rib existing between the pellets 3 and the inner surface. The fuel pellets are for example of UO 2  enriched to about 2À5% and sintered to approx. 95% theoretical density using a sintering atmosphere of H 2  at about 1700 C., and the cladding tube 1 may be of Zircaloy or stainless steel with an oxide film coating on its inner surface serving as a protection from chemical attack by fission gases. The radial height of the ribs 5 is at most about 0À1 mm., preferably at most about 0À05 mm., and at least 0À005 mm. The annular gap between the fuel pellets 3 and the cladding tube 1 (excluding the ribs 5) in the cold is in the range from about the radial height of the elements 5 to about 0À15 mm. There are at least eight ribs 5 evenly distributed over the inside surface of the cladding tube 1, with a particularly useful number of ribs being in the range from 16 to 32. The ribs may have in cross-section a trapezoidal shape. Alternatively they may have the shape of a circle segment formed between the circular periphery of the cladding tube bore and a chord thereof (Fig. 4, not shown) or a generally triangular shape with a rounded peak (Fig. 5, not shown). Preferably the ribs 5 are made integral with the cladding tube 1 as part of the ordinary tube manufacture, for instance in pilger step rolling or drawing operations, using a mandrel machined to conform with the shape of the desired tube bore cross-section. Cracks such as may occur in a fuel pellet 3 due to temperature differences are shown in Fig. 2, which cracks are widened at a power increase. With the ribs 5, however, the crack widening cannot result in local stress peaks and deformation in the opposite regions of the cladding tube 1 and the movement is merely transmitted by the friction forces at the separate ribs 5 as a general stretching of the whole tube section. Between the end surfaces of the fuel pellets 3, sharp discontinuities or protruding small platforms 9 are formed in the spacing elements 5 and each pellet therefore remains fixed in axial position and is prevented from moving axially relative to the cladding tube 1.

Abstract: 771,391. Corrugating. FLEXONICS CORPORATION. Feb. 15, 1955 [Feb. 15, 1954], No. 4557/55. Class 83 (4). [Also in Group V] Metal tubing 34, Fig. 1, is fed leftwards intermittently by a clamp 42 driven by a feed-screw 44 to a device 36 (see Fig. 9, not shown) for forming annular grooves. The tubing is then received between two pairs of jaws (166) 168 and (170) 172, Fig. 16, which are moved towards and away from the tubing by cams 186, 188 and 202, 204. The jaws 172 are also moved axially (a) to feed the tubing leftwards, when sufficient tubing has been fed by the clamp 42 which is then disconnected from the feed screw 44, and (b) to collapse the material between the grooves. The stroke of each of these axial movements is adjusted independently by (a) adjusting the distance between pivots 222 and 226, by means of a screw 294, of the linkage connecting a cam 230 with a slide 206, and (b) adjusting the position of a bell-crank lever 242, by means of a screw 254, in the linkage between a cam 268 and a slide 218. Each of these adjustments does not alter the starting position of the jaws. In operation, the tubing is grooved by a member 148, Fig. 12, the jaws 172 engage in a groove, the jaws 168 and member 148 disengage, and the jaws 172 push the tubing to the left. The jaws 168 then engage in the next groove, and the jaws 172 move to the left again to collapse the tubing between the grooves, Fig. 11. The jaws 168 are adjustably mounted and the whole of the collapsing mechanism is adjustably mounted relative to the grooving device 36. The mechanism including the clamp 42 for feeding the tubing, until it is fed by the jaws 172, includes a Geneva stop mechanism for producing the intermittent movement, and a variable gearing (see Fig. 3, not shown), which is controlled by a spring-urged handle 99 engaging in holes 97, to allow the length of the intermittent movements to be adjusted. The various parts of the apparatus are driven from a motor 302.

Abstract: 1,059,291. Measuring speed and fluid flow rate. UNITED AIRCRAFT CORPORATION. Feb. 5, 1964 [April 17, 1963], No.4907/64. Heading G1N. A water craft speed sensor using magnetohydrodynamic principles, is mounted on the craft below the water level and comprises an A. C. energized electromagnet 24 (Fig. 2) within an insulating shell on which are mounted two electrodes 28, 30, which pick up a voltage induced in the water, through which the craft is travelling, the voltage induced being proportional to the velocity of the craft. There may be a second pair of electrodes on the back side of the shell of Fig. 2, the shell being mounted so that there is a pair of electrodes on each side of the craft centre line. A second speed signal is thereby provided so allowing continuous operation of the sensor at high speed when a cavity might form in the water on one side of the craft. In Fig. 4 the two signals are fed to compensators 42, 44 respectively which eliminate extraneous fixed signals due to magnetic fields in the vicinity. The outputs of the compensators are amplified and sumomated in a selection network 56 which passes low error signals and rejects high error signals from a cavitating sensor. The output of the network 56 energizes a servomotor 60 which drives a speed indicator 62 and a feedback potentiometer 46. A negative feedback signal from the potentiometer 46 is summed with the compensated sensor signals at summing networks 48, 50. This provides an error signal between the speed sensed by the sensors and the indicated speed and the servomotor 60 is driven so as to reduce the error. A speed potentiometer 64 positioned by the servomotor 60 provides an input to an integrating servo amplifier 66. A tachogenerator 68 provides a signal which is summed with the speed signal from potentiometer 64 providing a velocity error signal to the amplifier 66 which drives the motor 70. The motor 70 speed then represents the craft velocity and may drive a counter 72 which indicates the distance travelled. In another embodiment Fig. 9 (not shown) there are two pairs of electrodes on one plane, the electrodes on a pair being diametrically opposed, one diameter being at 90 to the other. The electrodes are connected in a servo loop whereby a servomotor angularly displaces the four electrodes until the voltage induced in one pair is zero and is maximum in the other pair. The application of the sensor on a submarine to determine the current drift rate and direction of flow of water relative to the submarine is suggested.
