    摘要： A system of laterally supporting fuel assemblies for a fast reactor in a tight-packed array during operation of the reactor includes mechanical linkages operated through concentric operating shafts by motors located at the top of the reactor enclosure to force pressure bars against the sides of the array of fuel and reflector assemblies in the reactor at several vertical locations and at six locations around the reactor. Provision is made within the mechanical linkage to allow for expansion of the reactor core due to thermal transients and to compensate for variations in applied load due to radiation induced creep and stainless steel swelling.

    摘要： In a nuclear reactor neutron panels varying in thickness in the circumferential direction are disposed at spaced circumferential locations around the reactor core so that the greatest radial thickness is at the point of highest fluence with lesser thicknesses at adjacent locations where the fluence level is lower. The neutron panels are disposed between the core barrel and the interior of the reactor vessel to maintain radiation exposure to the vessel within acceptable limits.

    摘要： A method and an apparatus for testing, repairing or exchanging nozzles of the bottom of a reactor pressure vessel include inserting individual shielding containers into the reactor pressure vessel. Shafts pass through a shielding container and water-filled cartridges can be inserted into the shafts. Tubes for receiving probes of an in-core instrumentation are embedded into bottom plates of the remaining shielding containers and into bottoms of the cartridges. After removing a cartridge, a carrier for working tools can be introduced into the shaft. In this way the radioactive loading is considerably reduced by the probes inside or outside the reactor pressure vessel.

    摘要： A wall structure and a method for producing the wall structure. The wall ucture is comprised of substantially standardized building elements which, one preferred embodiment, interlocks with adjacent elements along both the top and bottom and the vertical side surfaces. The surfaces of the building elements forming the interior and exterior surfaces of the finished wall are preferably reinforced along one such surface thereof. During the formation of the wall structure, horizontally and vertically aligned grooves are provided in the completed wall to facilitate the location at which severing should occur as well as to facilitate the severing of the reinforcing members to permit selected sections of the wall to be simply, readily and inexpensively removed. In one embodiment, the reinforcing members may be steel plates while in another alternative embodiment, the reinforcing members may be comprised of horizontally and vertically oriented elongated reinforcing rods. In embodiments where reinforcing elements are provided along the interior and exterior wall surfaces, anchor members may be employed for securing the reinforcing members along the interior surface to those along the exterior surface of the wall. Similar members may be employed to secure the reinforcing plates.The individual building elements may either have smooth engaging surfaces or interlocking engaging surfaces.The method of forming the wall comprises forming alternating building elements within the frame at spaced intervals therealong and then forming the remaining building elements at the regions between the previously formed building elements, said frame provided with means for defining the guide grooves along which enforcing members may be severed. Upon completion of the wall, the grooves may either be left uncovered, exposing the reinforcing members therein or alternatively they may be filled with construction material of lesser or weaker strength than the basic construction material, which is preferably concrete.
