Measurements and analysis of steam generators rate from quenching of superheated debris beds. [PWR; BWR]
Light water reactor degraded core accident sequences have been postulated which lead to deposition of superheated debris beds in the reactor cavity. The debris beds are assumed to be cooled by an overlying pool of cooling water. The quenching of the debris is predicted to pressurize the containment building as a result of the steam generated during the quench process. Mechanistic models of debris bed quenching are required to predict the containment pressurization response to the steam and to the gases released from the concrete. The objective of this paper is to present recent experimental data for the rate of steam generation resulting from cooling of superheated packed beds of spheres by a saturated overlying pool of water. The effects of bed temperature and of sphere diameter are discussed.
