Overview

  • Motivations for periodic maintenance capability
  • Introduction to HYLIFE-II parametric CAD model
  • Details of maintenance capability
  • Future work
  • Questions and Feedback
slide3

History of Periodic Maintenance Issue

  • Many threats will assault HYLIFE-II chamber components
    • Radiation
      • He embrittlement
      • Volumetric swelling
      • Activation
    • Dynamic
      • Erosion
      • Pulsed thermal stresses and fatigue
  • Material performance uncertainties prompt an investigation into the economic tradeoffs of periodic chamber maintenance
    • Various material damage limits considered
    • Flibe pumping power and plant downtime accounted for
    • COE normalized to 100 dpa limit and no maintenance for 30 fpy
slide4

History of Periodic Maintenance Issue

  • Results of investigation presented at October 2002 ARIES meeting
  • LLNL starts parametric CAD model of HYLIFE-II chamber
    • Serve as a flexible platform for integrating previous concepts with future changes and innovations
    • Stimulate greater interaction between groups within HIF community
  • Design decided to be updated to support periodic maintenance
    • Be compatible with basic remote handling equipment
    • Make all components down to first-wall removable
slide5

HYLIFE-II Parametric CAD Model - Introduction

  • Previous graphical design work
    • Restricted to 2-D
    • Updates time consuming
    • Difficult visualization for uninitiated
    • No interference checking
  • Current model
    • Fully 3-D solid
    • Rapid design changes
    • Components export directly to finite element analysis routines
    • Subsystems easy to isolate
    • Animation and rendering capability
slide9

HYLIFE-II Maintenance Concept - Introduction

  • Broad features
    • Depends only on vertical cranes and simple robotic manipulators
    • Does not compromise any functional capability of previous chamber
    • Most internal components assembled as a single modular unit to be replaced in entirety
    • All structures down to first-wall easily accessible
slide10

HYLIFE-II Maintenance Concept - Animation

  • Procedure details
    • Remove chamber top
    • Pull beamline assembly
    • Extract main drive shafts
    • Lift out pocket nozzle assembly
    • Pull cross jet nozzles
    • Remove cross jet supports
    • Service first-wall
    • Reinstall new components in

Future Work on HYLIFE-II Model

  • Beamline region
    • Add vortex shielding systems
    • Beam neutralizers
    • Target injection apparatus
  • Main chamber
    • Cross-jet flow redirectors
    • First-wall detail
    • First-wall removal procedure
  • Rest of plant
    • Integrate chamber model with other plant systems
