    Abstract: A low cost, lanthanide-substituted, dimensionally and thermally stable, gas permeable, electrically conductive, porous ceramic air electrode composition of lanthanide-substituted doped lanthanum manganite is provided which is used as the cathode in high temperature, solid oxide electrolyte fuel cells and generators. The air electrode composition of this invention has a much lower fabrication cost as a result of using a lower cost lanthanide mixture, either a natural mixture or an unfinished lanthanide concentrate obtained from a natural mixture subjected to incomplete purification, as the raw material in place of part or all of the higher cost individual lanthanum. The mixed lanthanide primarily contains a mixture of at least La, Ce, Pr and Nd, or at least La, Ce, Pr, Nd and Sm in its lanthanide content, but can also include minor amounts of other lanthanides and trace impurities. The use of lanthanides in place of some or all of the lanthanum also increases the dimensional stability of the air electrode. This low cost air electrode can be fabricated as a cathode for use in high temperature, solid oxide fuel cells and generators.

    Abstract: Method and apparatus for remotely positioning end-effectors within conduits (10) having circuitous and/or inaccessible paths, and operating on the conduit walls. In one embodiment a lead line (16) having radially extending air foils (20) is inserted into the conduit (10) and the conduit pressurized up stream of the air foils (20); causing the lead end of the line (16) to sail through the conduit to the opposite end. The lead line (16) is attached to the end-effector, which can then be towed through the conduit (10). In a second embodiment the end-effector is controllably withdrawn back through the conduit (10) as the end-effector operates on the conduit walls. In another embodiment the lead line (16) controls the end-effector's forward movement as it operates on the conduit (10). In an embodiment where the end-effector is a grit blaster, the lead line (16) is attached to the end-effector with a tow coupling mechanism (86, 90) that spans between the openings in the grit blasting nozzle (80) to avoid direct impact of the grit on the mechanism and the lead line (16). In a fifth embodiment the end-effector is an array of detectors for mapping a characteristic profile of the conduit. Further embodiments take advantage of the benefit of being able to pull the end-effector along the conduit in both directions.

    Abstract: A self-powered fixed incore detector for a nuclear reactor has a neutron sensitive emitter element having a low neutron absorption cross section, such as a vanadium element, which extends the length of the active fuel region and generates a full length signal representative of full length power. A number of gamma sensitive emitter elements, preferably platinum but alternatively zirconium, cerium, tantalum, or osmium elements, provide sequentially increasing overlap with the neutron sensitive emitter element to define axial regions of the active fuel region and generate apportioning signals. The portion of the full length signal generated by the neutron sensitive emitter element attributable to each of the axial regions of the core are determined from ratios of the apportioning signals generated by the gamma sensitive elements. While the ratioing of the apportioning signals reduces the effects of delayed gamma radiation from the products of fission, the transient response can be further improved by filtering out this component of the apportioning signals generated by the gamma sensitive emitter elements.

    Abstract: Segmented stayrod (120) for restricting transverse displacement of a nuclear heat exchanger tube support plate (110a, 110b, 110c, 110d). The stayrod includes a first rod segment (130) interposed between the tubesheet (40) and the first support plate (110a), the first rod segment having an externally threaded riser (145) extending through the hole (115) formed in the first support plate. The stayrod also has a second rod segment (170) interposed between the first support plate and the second support plate, the second rod segment having an internally threaded end portion (210) for threadably engaging the threaded riser of the first rod segment. The second rod segment also has an externally threaded riser (190) extending through the hole formed in the second support plate. An internally threaded fastener (290) threadably engages the riser of the second rod segment for fastening the second rod segment to the second support plate. In this manner, the first support plate is captured between the first rod segment and the second rod segment. Moreover, the second support plate is captured between the second rod segment and the fastener, so that transverse displacement of the first support plate is restricted as the first support plate is captured between the first rod segment and the second rod segment and so that transverse displacement of the second support plate is restricted as the second support plate is captured between the second rod segment and the fastener.

    Abstract: There is disclosed low pressure steam turbine and generator low alloy steel disc rotors with extended useful life properties. A ring member of the disc rotor has disposed on it multiple weld layers of ferrous material, forming a weld region. The ring member is made of a low alloy ferrous metal alloy having less than about six weight percent alloying ingredients including chromium. The chromium content of the weld region increases overall from a portion of the weld region adjacent to the ring member to a portion of the weld region farthest from the ring member. This general increase is accomplished using weld metal of a single chromium concentration of between 9 % and 17 % chromium and varying the welding parameters.
