Abstract or Summary
  • A study has been made to investigate the fuel-cladding mechanical interaction (FCMI) in sphere pac fuels. An FCMI simulation has been constructed using the JVG Apparatus. This model has been used to investigate the mechanical interaction between a sphere pac bed and a cladding wall in terms of the cladding surface stresses and strains. Two measurement techniques were used to obtain these quantities; photoelastic coatings and strain gages. A variety of sphere pac beds were used. A primary consideration was the presence or absence of an infiltrating size fraction. For the cases in which this is absent, the load transmission to the cladding shows a high degree of non-uniformity. When an infiltrating fraction is present, the aforementioned phenomena is greatly mitigated. The surface stress distribution arising from a sphere contact consistently appeared as an "hourglass" shape with shear stress maximum values occurring along the vertical axis of the apparatus. Several analytic approaches were taken to model the tube hoop strains. In a very simplistic method, the fuel region was approximated as an incompressible fluid. The most successful approximation was to treat the sphere pac bed as a cohesionless, granular medium and proceed as in a rock mechanics solution.
