ABSTRACT:
The refractory section of a sintering furnace for sintering mixed oxide nuclear fuel pellets is disposed between a pair of glove boxes. Extensions from the opposite ends in communication with the sintering channel project through glove ports in the glove boxes, facilitating movement of boats containing the pellets through the sintering channel. Flexible material connects between the opposite ends of the refractory section and the glove boxes to isolate the extensions, glove boxes and sintering channel from the surrounding environment. The refractory section may be replaced by disconnecting the extension from boat pushing apparatus, displacing the furnace away from one glove box, gathering the flexible material and sealing it at three longitudinal locations and severing the seal at the intermediate location whereby both the glove box and the sintering furnace are maintained isolated. The opposite end of the refractory section is similarly disconnected from the glove box whereby a new sintering furnace can be disposed and coupled to the glove boxes while maintaining the sintering channel and glove boxes isolated.
