Description
Reflooding of a heated core is a complex phenomenon generally encountered in a large-break loss of coolant accident (LOCA) scenario, some times after the accumulator injection. The emergency core cooling liquid penetrates into the core and start cooling the hot rods. In Top - down rewetting, a liquid film flows down along tile wail. At the quench front, the liquid is violently sputtered off the wall and a spray of droplets is injected into the vapor field. 'The droplets bounce against the pipe walls. In Power reactor, rod bundle geometry is very prevalent. This study presents a new experimental apparatus that enable examination and validation of top-down rewetting in rod bundle geometry
