    摘要： An apparatus for cooling a substructure of a steam generator in a nuclear reactor is provided. The apparatus includes a plurality of stud bolts (110) fastening a skirt of the steam generator to a sliding base. Each stud bolt is provided at the center thereof with an axial through hole (112), a flange of the skirt is provided on one side thereof with a vent passage (122), and each stud bolt is provided with at least one vent hole (114) communicating with the axial through hole (112), thereby forming an air circulation/cooling path between the vent passage (122) and the axial through hole (112) via the vent hole (114).

    摘要： A device for the transport of large conduction heat flux between two locations of differing temperature includes a pair of fluid reservoirs (12, 14) for positioning at the respective locations connected by at least one duct (24), and preferably a plurality of ducts (24), having walls of a material which conducts heat. A heat transfer fluid, preferably a liquid, and preferably a liquid metal such as mercury, lithium or sodium, fills both reservoirs and the connecting ducts. An oscillatory axial movement or flow of working fluid is established within the ducts, with the extent of fluid movement being less than the duct length. Preferably the oscillatory movement is sinusoidal. Heat is transferred radially between the fluid and the duct walls and thence axially along the ducts. The rate of heat transfer is greatly enhanced by a physical mechanism which may be described as a high time-dependent radial temperature gradient produced by fluid oscillations. During most of each sinusoidal cycle, fluid in wall-near region has a temperature different from the core of the fluid column, with most of the temperature difference concentrated across a relatively thin boundary layer.

    摘要： A heat pipe configured to remove heat from a core of a nuclear reactor, the heat pipe comprising: an inner housing defining an inner volume configured to accommodate a heat source; an outer housing configured about the inner housing and the heat source; a wick positioned between at least a portion of the inner housing and at least a portion of the outer housing, wherein the wick comprises a capillary material, and wherein the wick defines an intermediate volume between the inner housing and the outer housing; and a working fluid within the intermediate volume, wherein the working fluid is configured to evaporate at a first end of the heat pipe, wherein the working fluid is further configured to condense at a second end of the heat pipe adjacent to a heat exchanger, and wherein the wick is configured to return working fluid that has condensed at the second end of the heat pipe to the first end of the heat pipe.
