摘要： A heterogeneous nuclear reactor of the seed-blanket type is provided wher the fissile (seed) and fertile (blanket) nuclear fuels are segregated axially within each fuel element such that fissile and fertile regions occur in an alternating pattern along the length of the fuel element. Further, different axial stacking patterns are used for the fuel elements of at least two module types such that when modules of different types are positioned adjacent to one another, the fertile regions of the modules are offset or staggered. Thus, when a module of one type is surrounded by modules of the second type the fertile regions thereof will be surrounded on all sides by fissile material. This provides enhanced neutron communication both radially and axially, thereby resulting in greater power oscillation stability than other axial arrangements. The arrangements of the fissile and fertile regions in an alternating axial manner minimizes the radial power peaking factors and provides a more optional thermal-hydraulic design than is afforded by radial arrangements.
摘要翻译：提供种子毯类型的异质核反应堆，其中易裂变（种子）和可育（核）核燃料）在每个燃料元件内轴向分离，使得裂变和可育区沿着燃料元件的长度以交替模式发生。此外，对于至少两种模块类型的燃料元件使用不同的轴向堆叠模式，使得当不同类型的模块彼此相邻放置时，模块的可育区域被偏移或交错。因此，当一种类型的模块被第二类型的模块包围时，其可育区域将在所有侧面上被裂变材料包围。这提供了径向和轴向的增强的中子连通，从而导致比其它轴向布置更大的功率振荡稳定性。以交替轴向方式的裂变和可育区域的布置使径向功率峰值因数最小化，并提供比通过径向布置提供的更可选的热液压设计。

摘要： A seed-blanket breeder reactor core having a flattened power density distribution resulting from selective loading of fissile material in the reactor core to achieve a desired radial reactivity distribution. The seed geometry of fuel modules near the periphery of the core is altered so that their reactivity worth is greater than centrally located fuel modules. The increased reactivity of the peripheral modules causes the gross power distribution in the core to flatten.

摘要： Seed-blanket type nuclear reactor cores are employed to burn thorium fuel with conventional reactor fuels, including nonproliferative enriched uranium, and weapons or reactor grade plutonium. In a first embodiment, the core is completely nonproliferative in that neither the reactor fuel, nor the generated waste material, can be used to manufacture nuclear weapons. In a second embodiment of the invention, the core is employed to burn large amounts of weapons grade plutonium with the thorium, and provides a convenient mechanism by which stockpiled weapons grade plutonium can be destroyed and converted into electrical energy. The cores of both embodiments are comprised of a plurality of seed-blanket unit fuel assemblies which have centrally located seed regions that are surrounded by annular blanket regions. The seed regions contain the uranium or plutonium fuel rods, while the blanket regions contain thorium fuel rods. The moderator/fuel volume ratios and relative sizes of the seed and blanket regions are optimized so that neither embodiment generates waste materials that can be employed for manufacturing nuclear weapons. A novel refueling scheme is also employed with the first embodiment to maximize seed fuel utilization, and further insure that the spent fuel cannot be employed for manufacturing nuclear weapons.

摘要： Seed-blanket type nuclear reactor cores (10,100) are employed to burn thorium fuel with conventional reactor fuels, including nonproliferative enriched uranium, and weapons or reactor grade plutonium. In a first embodiment, the core (10) is completely nonproliferative in that neither the reactor fuel, nor the generated waste material, can be used to manufacture nuclear weapons. In a second embodiment of the invention, the core (100) is employed to burn large amounts of weapons grade plutonium with the thorium, and provides a convenient mechanism by which stockpiled weapons grade plutonium can be destroyed and converted into electrical energy. The cores of both embodiments are comprised of a plurality of seed-blanket units (12, 102) which have centrally located seed regions (18,104) that are surrounded by annular blanket regions (20,106). The seed regions contain the uranium or plutonium fuel rods (22,110), while the blanket regions contain thorium fuel rods (26,118). The moderator/fuel volume ratios and relative sizes of the seed and blanket regions are optimized so that neither embodiment generates waste materials that can be employed for manufacturing nuclear weapons. A novel refueling scheme is also employed with the first embodiment to maximize seed fuel utilization, and further insure that the spent fuel cannot be employed for manufacturing nuclear weapons.
