Abstract
A nuclear reactor core assembly includes a support plate having a plurality of inlets for channeling water to a core lattice fixedly joined thereto. The lattice includes a plurality of flow channels, each including a respective separately removable fuel bundle. In a preferred embodiment, the core lattice includes a plurality of flow dividers joined together for allowing unrestrained expansion and contraction thereof, and which prevent crossflow of water therebetween.
Claims7
A nuclear reactor core having a longitudinal centerline axis comprising:
- a support plate having a plurality of inlets for receiving water;
- a core lattice joined to said support plate and having a plurality of longitudinally extending flow channels disposed in flow communication with respective ones of said inlets for channeling therethrough said water received from said inlets, said core lattice including:
- a plurality of longitudinally extending flow dividers laterally spaced apart to define said flow channels therebetween;
- and
- means for joining together adjacent ones of said dividers for allowing unrestrained expansion and contraction of said joined together dividers, said divider joining means comprising a plurality of posts fixedly joined to said support plate, each of said posts having a plurality of longitudinally extending grooves, and each of said dividers including an edge slidably disposed in a respective one of said post grooves;
- and
- a plurality of fuel bundles, each fuel bundle being disposed in a respective one of said flow channels, and being effective for boiling said water.
