In the course of a joint research and development program conducted by CISE, Ansaldo, and NDA, a conceptual design for a 300 Mw(e) direct cycle fog- cooled light watermoderated reactor was developed, indicating attractive economics (6.5 mills/kwh) and promising improved operational safety characteristics over boiling water systems. In addition, heat transfer data on wet steam in fog flow conditions obtained by CISE and others were examined analytically to develop an insight into the mechanism of burnout heat transfer under fog flow. The results of these studies suggest that the supply of liquid to the heated wall in the vicinity of the burnout region is mainly through diffusion of liquid droplets from the bulk of the stream, and that burnout predictions might be possible from formulations describing the rate of liquid cross flow based on a droplet diffusion model.
