Modification V to the computer code, STRETCH, for predicting coated- particle behavior

Cited by 0Open access

Abstract

Several modifications have been made to the stress analysis code, STRETCH, in an attempt to improve agreement between the calculated and observed behavior of pyrocarbon-coated fuel particles during irradiation in a reactor environment.Specific areas of the code that have been modified are the neutron-induced densification model and the neutron-induced creep calculation.,Also, the capability for modeling surface temperature variations has been added.HFIR Target experiments HT-12 through HT-15 have been simulated with the modified code, and the neutron-fluence vs particle-failure predictions compare favorably with the experimental results.Listings of the modified FORTRAN IV main source program and additional FORTRAN IV functions are provided along with instructions far supplying the additional input data.
