    摘要： In a boiling water reactor nuclear plant, hydrogen is injected into the feed water to neutralize radiolysis which causes stress corrosion in stainless steel components. It has been discovered that by inhibiting volatile ammonia, and other gaseous nitrogen compounds from leaving the liquid phase portions of the plant to the steam phase portions of the plant, radiation is reduced to acceptable levels. Formation of ammonia is inhibited chemically, by altering the reaction paths for volatile nitrogen species with trace additives in the parts per billion range, suitable additives include nitrous oxide, copper, zinc, carbon dioxide, and other components. It has also been found that by manipulating the pH, the formation of the voltage nitrogen compounds, especially ammonia, is decreased. Similarly, by physically altering plant operating conditions to reduce sparging or scrubbing of the gases from areas of high radiation, confinement of the N-16 within the liquid phase of the plant within the reactor vessel occurs. It is further found that by decreasing the total hydrogen concentration in the core region, the N-16 volatility can be limited. This includes alternate hydrogen injection points and enhancement of the hydrogen-oxygen recombination reaction by e.g., catalysis by radiation or by surfaces. The possibility of increasing the N-16 holdup time in the steam phase is also considered. Finally, the concept of operating at a higher electrochemical potential which requires a lower hydrogen concentration and hence less N-16 converted to the volatile form is also described.

    摘要： The glass forming chamber in which glass is formed into a continuous sheet by floating it on the surface of molten metal is provided with a series of heat exchangers in an enclosed shell above the chamber and protective atmosphere gases are passed through these heat exchangers to preheat the atmosphere gases which are then directed through conduits into headers and distribution manifolds located within the headspace of the operating portion of the chamber in the vicinity of the glass being formed. The chamber is provided with conventional electrical heating elements connected to bus bars located within the shell containing the heat exchangers, and the heat exchangers are located close to the bus bars to extract heat from them during operation and thereby prolong their useful lives.

    摘要： A medical waste disposal container has a unitary body structure formed of a substantially flat sheet having a plurality of laminated layers of compact fiberboard, and one or more thin pliable layers of absorbtion resistant plastic material. The laminated sheet material contains a plurality of foldable sheet portions that are scored, wrapped at corners and adhesively joined together to define a bottom, sidewalls and a top of the body structure. The top has an opening, that is closeable by way of a flap formed in the sheet material, for insertion of discarded medical waste. The interior of the container is preferably coated with an absorption resistant material to effectively provide a leakproof seal at the intersections of its sidewalls and bottom. Adhesion and additional sealing of the foldable sheet portions is achieved in the course of manufacture by irradiating the laminate sheet material with infrared light, which causes the plastic layer that forms the outer wall surface of the sheet material to become tacky, so that it becomes intimately bonded to an adjacent folded sheet portion to which it is joined, thus securing the wrapeed sheet portions together.

    摘要： A discarded medical material container comprises a body of sheet material having laminated layers of compact fibrous material and material that is effectively impervious to the passage of fluid. The sheet material is formed into foldable panels that are joined together to define a bottom, sidewalls and a top of the body. The top has a closeable opening for the insertion of discarded material into the container and a closure tab. The top is formed of a first, interior panel of the sheet material having a region that is sectioned to define a plurality of flaps extending inwardly from the contour of the region, so as to define an opening in the first panel of sheet material, and a second, outer panel of sheet material, disposed atop the first panel. The second panel has a cut to define an aperture in the shape of a generally flexible tab overlying the region in the first panel and sized to close the aperture. A slit-score causes each flap to assume a generally downwardly bent condition. The slit-score is adjacent to and set back beneath an edge of the cut through the second panel, so that a portion of the second panel extends over the slit-score, thereby effectively preventing each flap from being bent outwardly through the aperture in the second panel.
