Abstract
1,176,565. Breaking metals. NUCLEAR DESIGN & CONSTRUCTION (1966) Ltd. 30 May, 1968 [1 June, 1967], No. 25387/67. Heading B3E. [Also in Division G6] Apparatus for dismantling a spent fuel element string 14 consisting of a number of fuel elements mounted on a tie bar 15 connected to a standpipe shield plug 16, includes means for applying intense heat to a selected point on the tie bar to raise its temperature to that approaching melting point and applying tension to the tie bar to part it. As shown, the apparatus comprises a shielded vessel 1 having a tube 3 suspended from a platform 2 the fuel element string 14 being lowered into the tube by a grab (not shown) through a pipe 4 closed by a valve 5. The string 14 is supported by a sleeve 13 movable along the tube 3 by a chain elevator 21. A tie bar puller 6 has a passage 7 leading to a magazine 8 for containing parted lengths of the bar. The bar is longer than the combined length of the fuel elements and is retained at the top end by a shield plug 16; hence, by adjusting the tube 3 a length of the bar may be exposed either at the lower end (as shown) adjacent the retaining nut 22 or at the top end adjacent the lower surface of the spiral neutron shield portion 17 of the plug 16. A heating source, e.g. a water-cooled induction coil (Fig. 2, not shown) is placed around the exposed length of the bar to heat it in the region 1000-1200 C., the puller 6 then being operated to part the bar. The first parting is made at the top end to separate the bar from the plug 16, the second and subsequent partings being made at the lower end, the bar being progressively pulled down through the string by the puller 6. The parted bar lengths in the magazine 8 are sent to a disposal void through a pipe 11.
