COVE1; creep collapse for oval fuel pin tube. [CDC6600; FORTRAN IV]

Technical Report ·

OSTI ID:6488672

Mohr, C L

COVE1 is a time-dependent incremental creep collapse code that estimates the change in ovality of a fuel pin cladding tube. Application is intended primarily for tubes manufactured from zircaloy. Therefore, provision is made for the effects of anisotropy in the Prandtl-Reuss flow equations for inelastic incremental deformations by using the P and R strain ratio coefficients. The creep deformation is computed in terms of the length of the collapse zone and includes the effects of changes in temperatures, system pressure, fill gas pressure, and neutron flux levels.CDC6600; FORTRAN IV; SCOPE 3.4.2; 135K (octal) storage is required for execution.
