摘要： A fuel channel assembly for a nuclear reactor may include an inner conduit received within an outer conduit that has an outer upper end connectable to a coolant outlet and an outer lower end. The inner conduit may have an inner upper end connectable to a coolant source and an inner lower end axially spaced apart from the inner upper end and disposed within the outer conduit to enable coolant to circulate from the coolant source to the coolant outlet through both the inner and outer conduits. A fuel bundle chamber may be between an inner surface of the outer conduit and an outer surface of the inner conduit and may at least partially laterally surround the inner conduit. The fuel bundle chamber fluidly connecting the inner lower end and the outer upper end to enable the coolant to flow upward through the fuel bundle chamber.

摘要： Fuel supports (148) have specially configured flow paths useable in reactor cores (36) to achieve desired levels of flow at given positions. Any number of differently-configured inlet orifices (195), from three to hundreds, are useable in a given core (36). Inlet orifice (195) configuration may include diameter sizing or presence of flow blockages such as filters, venturis, choke plates, and/or obstructions. Fuel supports (148) may be positioned within a core plate (49) in the nuclear reactor, with openings for a control blade (20) and instrumentation tubes (50) to pass through or between the fuel supports (148). Different fuel support (148) configurations may be used at outer core periphery, inner core periphery, and central core portions. Example methods configure fuel support (148) characteristics by examining the effect of modifying flow loss coefficients at particular bundle locations and configuring associated inlet orifices (195) to achieve the modified flow loss coefficients, if the effect is a positive one.

摘要： [Problem to be Solved] To suppress problems due to a flow of a primary coolant while easily distributing a flow rate of the primary coolant to fuel assemblies.
[Solution] A pressure-loss adjusting member 60 includes: a pressure-loss adjusting hole 62 that can cause light water to pass therethrough in a state with a pressure-loss being increased more than that of when light water flowing around the fuel assembly passes through only a core support plate flow hole formed in a lower core support plate; and a core support plate engaging unit 70 that can be engaged with the lower core support plate by being inserted into the core support plate flow hole. Accordingly, the flow rate of light water flowing toward the fuel assembly can be reduced by arranging the pressure-loss adjusting member 60 between a lower nozzle of a fuel assembly having a small pressure-loss and the lower core support plate, and rattling or the like of the pressure-loss adjusting member 60 can be suppressed by engaging the core support plate engaging unit 70 with the lower core support plate. As a result, problems due to the flow of light water can be suppressed, while easily distributing the flow rate of light water to the fuel assemblies.
