  • Patent number: 7412021
    Abstract: An advanced gray rod control assembly (GRCA) is for a nuclear reactor. The reactor has a plurality of fuel assemblies each including numerous elongated fuel rods supported in an organized array by substantially transverse support grids, and a plurality of guide thimbles disposed through the support grids and along the fuel rods. The GRCA includes a spider assembly structured to provide controlled insertion of gray rod assemblies within the thimbles of the fuel assembly, thereby controlling the rate of power produced by the reactor. Each gray rod assembly includes an elongated tubular member, a first end plug, a second end plug, a substantially pure silver neutron-absorber disposed within the tubular member, and a support tube surrounding the neutron-absorber within the tubular member to resist silver-swelling. Delta-power of the reactor is improved by minimizing the exposed surface area of the absorber and distributing it among all of the rods of the GRCA.

  • Publication number: 20060222140
    Abstract: In a nuclear reactor fuel assembly structured to support at least one non-linear fuel rod, the nuclear reactor fuel assembly includes at least two support grids, a first support grid and a second support grid structured to support at least one fuel rod in a non-linear shape. Each support grid has a plurality of generally square cells and wherein the cells on the first support grid and the second support grid are generally vertically aligned. Each cell has a first side, a second side, a third side, and a fourth side. Each cell further has protrusions extending from each the cell sides, wherein the protrusions are selected from the group including a spring, a dimple or an extended dimple. A spring is always disposed opposite of a dimple or an extended dimple. The first support grid includes at least one cell having an extended dimple extending from at least one cell side.

  • Patent number: 6738447
    Abstract: A high energy absorption top nozzle for a nuclear fuel assembly that employs an elongated upper tubular housing and an elongated lower tubular housing slidable within the upper tubular housing. The upper and lower housings are biased away from each other by a plurality of longitudinally extending springs that are restrained by a longitudinally moveable piston whose upward travel is limited within the upper housing. The energy imparted to the nozzle by a control rod scram is mostly absorbed by the springs and the hydraulic affect of the piston within the nozzle.
