Auslegungsvorschläge für Deckenreflektoren mittelgrosser Hochtemperaturreaktoren am Beispiel des HTR-500
In this thesis several concepts for top reflectors in medium size high temperature gas cooled reactors (HTGCR's) are investigated. The HTR-500 serves as an example for reactors of this size. The main concern of the investigation is structural strength at high temperatures. The conventional design contains metallic structural parts which are not stable at very high temperatures and might failduring hypothetical accidents. The failing of the support structure would cause the top reflector to fall down an top of the pebblc bed core. Closer to the core, it would be more effective, thus it would lead to an increase in reactivity. The thesis contains the resuits of calculations for two different concepts, one of them being an arch construction, the other one a beam construction. The feasibility of both concepts is evaluated regarding their respective mechanical properties. The arch-based construction Shows advantages in its safety and it is Basier to build under the given conditions.
