Abstract: A multi-opening oven assembly for simultaneously heating a plurality of blanks, for example aluminum blanks, before forming the heated blanks in a production line is provided. The oven assembly includes vertically aligned shelves to present a plurality of chambers for heating the blanks. A table including an entry side platform and an exit side platform moves vertically along the oven assembly. A rail system extends along the platforms and the shelves to convey the blanks in and out of the chambers. Once one set of heated blanks is removed from a first chamber, the table moves vertically to a second chamber and is ready to receive the next set of heated blanks. A continuous supply of heated blanks is provided for high throughput. The oven assembly is preferably disposed in a press adjacent a forming station of an existing production line and thus, no additional floor space is required.

Abstract: The invention relates to methods for mitigating the recontamination of carbon steel surfaces in a nuclear reactor or related water-containing systems and components, which have undergone a decontamination process. The methods include conducting a passivation process of the carbon steel surfaces directly following completion of the decontamination process, prior to the system or component being returned to service. In certain embodiments, a chelating agent is used in the decontamination process and is retained following completion of the process, for use in the subsequent passivation process. The passivation process forms a passivation film that is effective to reduce recontamination of the decontaminated carbon steel surfaces.
