The CYGR05 computer program is a production program developed from the CYGR04 computer program for the analysis of axisymmetric deformations of oxide fueled rod-type fuel elements. CYGR05 incorporates improved numerical methods, a capability for analyzing either single zone or radially zoned, duplex fuel, a capability for simultaneous, coupled analysis of all rod segments, a time and temperature dependent fission gas release model with a coupled swelling model, and improved cladding stress-free growth and creep representations. The program is also capable of performing analyses with CYRG04 models. It obtains the same results as CYGR04 in those cases.
