Description

A two-dimensional core-wide heat-up code MUFLAR has been developed, which calculates two-dimensional flow of steam-hydrogen mixture and radial heat transport by thermal radiation between fuel rod groups. Constitutive models are based on those verified through analyses of wide range of experiments. The code has been applied to an analysis of TMI-2 core damage behavior. The calculated results are in good agreement with the results of recent core examinations. The analysis indicates that cross flow has a radial averaging effect on core temperature. (author)
