A Detailed fuel rod design is carried out for the first time in the development of Supercritical-pressure Light Water Reactor (Super LWR). The fuel rod design is similar to that of LWR, consisting of UO2 pellets, a gas plenum and a Stainless Steel Cladding. The principle of rationalization of the criteria for anticipated transients of Super LWR is developed. The fuel rod failures can be conservatively prevented by limiting the cladding strain level within an elastic region, preventing the cladding buckling collapse, and keeping the pellet centerline temperature below its melting point. The FEMAXI-6 fuel analysis code of Japan Atomic Energy Research Institute (JAERI) is used to evaluate the fuel rod integrities in anticipated transient conditions. Detailed analyses have shown that allowable limits to the maximum fuel rod power and maximum cladding temperature can be determined to assure the fuel integrities. These limits may be useful in the plant safety analyses to confirm the fuel integrities during anticipated transients.
