Experimental Study of Debris-Bed Coolability under Pool-Boiling Conditions (PWR; BWR; LMFBR)

摘要

An experimental investigation has been conducted into the dryout of a bed of inductively heated particles cooled by an overlying liquid pool. Particles of diameters 4763 mu m, 3175 mu m, 1588 mu m, and 589-787 mu m have been used. Acetone and water have been used as the coolant with bed heights varying from 5 to 40 cm. Results are presented in terms of the dryout heat as a function of bed height. It has been found that the ratio of the overlying liquid pool height to the particulate bed height can influence the dryout heat flux. Comparison with other experimetal studies was good and a comparison with proposed theoretical models was also made. (ERA citation 08:040899)
