  • Patent number: 8185836
    Abstract: An apparatus generating a graphical image of a core of a boiling water reactor (BWR) using at least one data set of channel deformation data including: a computer system including a display device for presenting the graphical image and a processor generating the graphical image using the at least one data set; the graphical image of the core includes symbolic representations of control blades arranged in the core, indicia identify each control blade, and indicia regarding deformation of channels adjacent each control blade, and a viewer software tool executed by the processor which accesses the at least one data set and determines a location in the core of the control blades and channels, and correlates the deformation data with the channels for display on the graphical image.

  • Publication number: 20080275889
    Abstract: A method and system for creating a functional depth chart of an organization is provided. The method and system may include comparing a selected function requirement of the organization with a selected employee, if an employee is present within the organization. The method and system may also illustrate the results on the aforementioned comparison in a functional depth chart. The method and system may also illustrate a plurality of functional depth charts. The method and system may also include a search function.

  • Publication number: 20070177710
    Abstract: In a method of determining a cell friction metric for a control cell of a nuclear reactor, a channel face fast fluence and/or a channel face controlled operation parameter is determined for all channels. A total bow value is calculated for each channel based on the channel face fast fluence and/or channel face control parameters. For each channel, a channel wall pressure drop parameter is determined, and a total bulge value is calculated for each channel using the channel face fast fluence and channel wall pressure drop parameters. Total deformation at specified channel axial elevations for the cell is determined based on the total bow and bulge values. A control blade axial friction force value is calculated at each axial elevation based on the total deformation, along with channel stiffness and channel-control blade friction coefficient values. A maximum friction value is selected as the cell friction metric for the cell.

  • Publication number: 20070153963
    Abstract: A zirconium alloy suitable for forming reactor components that exhibit reduced irradiation growth and improved corrosion resistance during operation of a light water reactor (LWR), for example, a boiling water reactor (BWR). During operation of the reactor, the reactor components will be exposed to a strong, and frequently asymmetrical, radiation fields sufficient to induce or accelerate corrosion of the irradiated alloy surfaces within the reactor core. Reactor components fabricated from the disclosed zirconium alloy will also tend to exhibit an improved tolerance for cold-working during fabrication of the component, thereby simplifying the fabrication of such components by reducing or eliminating subsequent thermal processing, for example, anneals, without unduly degrading the performance of the finished component.
