Abstract

1,148,881. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 4 May, 1966 [13 May, 1965], No. 20221/65. Heading G6C. In a nuclear reactor fuel assembly, a cluster of fuel pins 6 are held parallel to each other by the spacer grid 1. The latter is formed of stainless steel strip, shaped into octagonal cells 2, each containing a pin. The grid is secured to certain of the fuel pins by a sleeve 7, welded to the pin. The grid and pin are assembled by sliding the rod into a cell through the recesses 5 and then rotating the pin to cause the projections 9, to engage the grid. In an alternative form the sleeve 7 forms a section of the pin sheath.
