A SURVEY OF COOLANT VAPORIZATION EFFECTS IMPORTANT TO FAST REACTOR SAFETY

摘要

The role of coolant vaporization phenomena of importance in fast reactor safety analysis is evaluated for the various abnormal operating conditions which may lead to vaporization. The hydrodynamic, thermal, and nuclear phenomena of particular importance are discussed in detail, their methods of prediction are reviewed and evaluated, and recommendations pertaining to future analyses and experiments are made. In general, experimental and analytical techniques are available to give insight to the gross behavior of vaporizing coolant. However, the technology is insufficient at present to make accurate predictions.
