Abstract: This thesis deals with the use of reactor and weapon grade plutonium in High Temperature Gas Cooled Reactors (HTR) with spherical fuel elements. As an example, a 350 MW$_{th}$ MODUL type reactor is investigated in detail. The purpose of the study was to find the possibilities and linaits of using plutonium efectively in a Pebble Bed HTR. Fuel cycles were optimized with respeet to different goalsunder the condition that safety requirements Traust be strictly fulfilled. A comprornise between opposite optimization criteria (e.g., higher destruction rate or smaller residual amount of plutonium in the spant fuel) was achieved. Calculational studies of plutonium cycles in a Pebble Bed Reactor were performed using the VSOP Code. The results show that a Pebble Bed Reactor potentially provides for extreme high burnup of plutonium. The high burnup was achieved by separate ioading of the plutonium in feed and of uranium in breed type fuel elernents. Both fuel element types undergo different numbers of Passes through the reactor until the intended burnup is achieved. Two reference cases are derived from a parametric study, one for the use of reactor grade plutonium with uraniuna, and another one for weapon grade plutonium with thorium as the breed material . Both reference cycles prove that the HTR-350 Module reactor offers a good concept for the destruction of both plutonium grades.
