1,067,158. Jointing by rolling. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 20, 1964 [Nov. 7, 1963], No. 44061/63. Heading B3M. [Also in Division G6] A fuel element of the type comprising a number of part annular fuel plates 3 supported at longitudinal edges by radial support members 4 to define a series of coaxial tubes, is manufactured by assembling the fuel plates with their longitudinal edges loosely supported in grooves in the radial supports, mounting the assembly on a mandrel 5 and then passing it between radially disposed rollers 13 which exert a radially inward compression on each support, thereby closing the grooves to grip the plate edges. Each roller is carried on an hydraulic plunger 10, whose inward travel is limited by an adjustable stop-nut 15. The plate edges received in the radial support grooves are preferably of dovetail form. The loose assembly may be heated prior to deforming, and may be pulled between the rollers by an hydraulic ram. |
