摘要： The present invention relates to a nuclear reactor core and fuel elements therefore. Stackable fuel elements, having the usual coolant holes machined therethrough, are formed with grooves along their vertical extent for alignment with similar grooves on adjacent fuel elements to define additional coolant passageways. These grooves provide coolant passageways between adjacent fuel elements enhancing the mechanical stability of the core. Furthermore, these additional coolant passageways allow a more efficient utilization of reactor core space and permit coolant escaping into the interstices between adjacent ends of blocks to be collected at these additional coolant passageways. Stability may be enhanced further by means of complementary elevations and depressions formed on end faces of the fuel blocks.
摘要翻译：本发明涉及核反应堆核心和燃料元件。具有通过其加工的通常的冷却剂孔的可堆叠燃料元件沿其垂直方向形成有凹槽，用于与相邻燃料元件上的相似凹槽对准以限定额外的冷却剂通道。这些凹槽在相邻的燃料元件之间提供冷却剂通道，增强了芯的机械稳定性。此外，这些额外的冷却剂通道允许更有效地利用反应堆堆芯空间并允许冷却剂逸出到在这些另外的冷却剂通道处被收集的块的相邻端之间的间隙中。通过在燃料块的端面上形成的互补的高度和凹陷可以进一步增强稳定性。

摘要： A nuclear reactor can include a pressure vessel for containing a pressurized moderator at a first pressure. The nuclear reactor can also include a plurality of fuel channels for a coolant fluid at a second pressure. The plurality of fuel channels are fluidly connected at inlet ends thereof to a coolant supply conduit and are adapted to receive nuclear fuel bundles and to be mounted within the pressure vessel and surrounded by the moderator. The outlet ends of the fuel channels are fluidly connected to a coolant outlet conduit to enable the coolant fluid to circulate from the coolant supply conduit through the fuel channels to the coolant outlet conduit. The plurality of fuel channels maintain separation between the coolant fluid circulating within the fuel channels and the moderator.

摘要： This invention provides a nuclear reactor design that can enable automated or semi-automated manufacturing of a small reactor in a mechanized factory. This is possible by following a layered approach to combine simple "plate" geometries with the use of diffusion bonding and computer aided manufacturing techniques that integrate all the fuel, axial reflectors, axial gamma and neutron shields, fuel gas plenum, heat removal mechanism, primary heat exchangers and moderator all in one block or component. The final assembled block has no welds and limits or eliminates manual operations. This design has the potential to reduce the fabrication time of an entire nuclear reactor to just a few days.

摘要： A heat exchanger for cooling a nuclear reactor core is disclosed herein. The heat exchanger can include a first stage including an input configured to receive a working fluid from an external source into the heat exchanger, and a first plenum configured to envelope a moderator heat pipe extending from the nuclear reactor core. The heat exchanger can further include a second stage including an output configured to remove a working fluid from the heat exchanger to the external source, and a second plenum configured to envelope a power heat pipe extending from the nuclear reactor core, wherein the first plenum and the second plenum are in fluid communication and configured such that the external fluid must traverse the first plenum and over the moderator heat pipe before entering the second plenum and traversing over the power heat pipe.
