Some possible effects of hot walls on flow in PWR downcomers during the ECCS injection phase of a loss of coolant accident, following the end of blowdown

Creators

Description

The phenomena which may limit the flow rate of a boiling liquid penetrating into a restricted space with walls initially above the saturation temperature are discussed and several ''limiting'' or ''idealized'' analyses are presented. Comparison is made with experimental results obtained in small scale apparatus duplicating some of the essential features of the downcomer region of a pressurized water reactor. The possible application of these results for predicting the behavior of large scale tests is discussed
