Abstract: A bottom reflector for a gas-cooled nuclear reactor of the pebble bed type is composed of vertical graphite columns of hexagonal cross-section, each divided several times into separate blocks or layers one above another. The columns contain vertical bores for cooling gas and one or more fuel element discharge ducts. Those vertical bores (35) which intersect the top (inclined) face (20) of the bottom reflector continue down only a limited distance below this top face and then lead into other bores (38) of considerably larger dia. Pref., the bores of smaller dia (35) are limited to the uppermost graphite block (30) of a column (26). Pref. also, the top and bottom ends of the large dia. bores (38), occupying the remaining block of the column, have an increased dia. pref. in the form of a conical divergence. Used for a gas-cooled nuclear reactor comprising a core composed of numerous spherical fuel elements. The arrangement enable the flow resistance to the hot gas passing downwards through the ducts in the bottom reflector to be considerably reduced, while still maintaining the small dia. in the upper part of the reflector, which is necessitated by the size of the spherical fuel elements.

Patent DE-3116735-A1 (DE)
Title: Integrated infrared plane emitters with a thermally stable infrared image
Inventor: JANES MANFRED DR
IPC: F41J2/02
Filed: 1981-04-28
Abstract: According to the invention, an infrared image is composed from small isothermal plane emitters in a similar way to the construction of an image in the image-scanning method by grey gradations. Devices of this kind which emit infrared images are needed, for example, for the investigation of infrared homing heads. To prevent the possibility that the small plane emitters (2), which can be designed differently according to the particular requirements, will exert a thermal influence on one another, a rearwardly open honeycomb structure (3) consisting of heat-insulating plastic, having mirrored honeycomb inner surfaces (5), is used as a mounting for these (see Figure 1). Fitted into the front honeycomb apertures are the hexagonal radiation elements (2), the front sides of which emit in the infrared range in the manner of black or grey bodies. The power required for generating the infrared image is supplied by a laser, the beam (6) of which travels over the open rear side of the honeycomb structure. The intensity of this beam is modulated in such a way that the power supplied to the radiation element generates, on the emitting front sides of these, the temperature which is required by the particular infrared image. The laser beam reaches the rear side (4) of the radiation element through its rear honeycomb aperture either directly or after reflection on the mirrored honeycomb inner surfaces. So that the laser radiation can be absorbed as completely as possible, the rear side (4) of the radiation element is blackened. <IMAGE>
