Bison Fuel Performance Studies on the Effect of Narrowing TREAT'S Pulse Width

摘要

The fuel performance studies on the effect of various TREAT pulse width enhancements show that there are very small deviations from the baseline case regarding fuel thermal parameters. Cladding surface temperature variations showed about 5% lower temperatures compared to the baseline PWR case. The large variation is seen when comparing cladding mechanical properties with deviations of over 25% in the maximum hoop stress and ～60-70% lower strain rates which are important to cladding plastic deformation and ductility.
