Abstract

1,208,877. Fuelling reactors. BROWN BOVERI/KRUPP REAKTORBAU G.m.b.H. 27 May, 1969 [25 May, 1968], No. 26812/69. Heading G6C. A system for conveying spherical fuel elements 15 to a reactor 1 permits the elements to travel along the conveying pipe 6 at high speed but enables the elements to enter the reactor at low speed by producing a retarding action. A gas driven by a fan 10 is used for both the conveying and retarding functions. The fuel elements 15 are supplied by a feed pipe 16 and conveyed by the pipe 6 to a discharge nozzle 19, the conveying gas being controlled by a valve 14. The pipe end 7 adjacent the nozzle 19 has perforations 8 and is enclosed in a chamber 4 whereby the gas may re-circulate back to the fan 10 by a pipe 9. The gas for the retarding function is supplied by a pipe 12 controlled by a valve 13, this gas passing in the opposite direction through the nozzle 19 and entering the pipe 9 for return to the fan. Each of the single pipes 6, 9, 12 may be replaced by a number of pipes in parallel (Fig. 2, not shown).
