    • A nuclear reactor including a core having nuclear fuel material, moderator material and a semiconductor device. The core by itself has a subcritical mass. The reactor also includes a fission inducing source which is movable from a first position outside the core to a second position inside the core, whereby the core becomes critical. Finally, the reactor includes a neutron reflector which surrounds the core and includes an opening to permit the insertion and removal of the fission inducing source. For, for instance, terrestrial applications the reactor would also include a shield surrounding the neutron reflector. Preferably, the core consists of concentric cylinders of the semiconductor device, the nuclear fuel material, and the semiconductor device, whereby the nuclear fuel material is sandwiched between layers of the semiconductor device. The nuclear fuel material is in the form of a thin foil or deposit which has a thickness in the range of 1.5 mg/cm to 10 mg/cm , which thickness depends on the particular type of fuel used. The semiconductor device includes a semiconductor material that has a high electrical collection efficiency and is able to survive both the high temperatures and high particle fluences generated by the nuclear fuel material. The semiconductor device is selected from the group including p-n junction diodes and Schottky barrier diodes.
    • 一种核反应堆,包括具有核燃料材料的核心,调节剂材料和半导体装置。 核心本身具有亚临界质量。 该反应堆还包括一个裂变诱导源,该裂变诱发源可从该核心外的第一位置移动到该核心内的第二位置,由此该核心变得关键。 最后,反应堆包括一个中子反射器,该中子反射器围绕着核心并包括一个开口以允许插入和移除裂变诱导源。 例如,对于地面应用,反应堆还将包括围绕中子反射器的屏蔽层。 优选地,芯由半导体器件的同心圆柱体,核燃料材料和半导体器件组成,由此核燃料材料夹在半导体器件的层之间。 核燃料材料为厚度取决于所使用的燃料的具体类型的厚度为1.5mg / cm 2至10mg / cm 2的薄箔或沉积物的形式。 该半导体器件包括半导体材料,该半导体材料具有高的电收集效率并且能够承受由核燃料材料产生的高温和高粒子能量。 半导体器件从包括p-n结二极管和肖特基势垒二极管的组中选择。
