BOILING NUCLEAR REACTOR WITH INTERNAL SUPERHEATING
The coolant and moderator tank of the boiling reactor is divided into three superposed zones: an upper vapor zone, and a middle and lower liquid zone, the latter two being hermetically separated from each other. Hollow fuel elements which possess a bottom, a top, and a side opening extend from the bottom of the lower zone into the vapor zone; the side opening is situated just below the separating partition. Subcooled coolant is introduced into the middle zone, flows from there into the lower zone through an external connecting tube, and rises in the fuel elements where it is partly converted into steam. The steam is superheated in the top part of the fuel elements and the unevaporated liquid leaves the fuel elements by the side openings. (NPO)
