The paper deals with the method employed to arrest the temperature of vertical nuclear fuel-clad so as to keep clad fairly below the softening temperature. Objective of the paper is to control the generation of solid, liquid and gaseous nuclear waste as a result of split or rupture in clad. The fuel and clad have been modeled. The governing equations with adequate boundary conditions were solved using marching technique. The computer program was developed to predict the rewetting velocity. The paper mainly covers the generation of rewetting transients which were used to predict the rewetting velocities. Method of calculating acceptable rate of rise of clad temperature such that complete clad is saved from attaining softening temperature is discussed in detail in the paper.
