A method of more rapidly and uniformly heating bundles of zirconium alloy tubes in a vacuum annealing furnace utilizes an induction coil to preheat the entire bundle as it is being moved into the hot zone of the furnace.

Vacuum annealing of zirconium based articles

A system for spraying liquid sodium onto impurities associated with liquid dip seals of nuclear reactors. The liquid sodium mixing with the impurities dissolves the impurities in the liquid sodium. The liquid sodium having dissolved and diluted the impurities carries the impurities away from the site thereby cleaning the liquid dip seal and surrounding area. The system also allows wetting of the metallic surfaces of the dip seal thereby reducing migration of radioactive particles across the wetted boundary.
