Gas cooled nuclear reactors

Creators

Description

The graphite sleeves of a fuel stringer of a gas cooled nuclear reactor are formed with a rib/groove profile on their external surfaces in order to increase the resistance of flow through an annular passage between the stringer and the seal bore of a channel during raising or lowering of the fuel stringer from or into the reactor core. The ribbing has an asymmetric profile so that the resistance to coolant flow is less when the stringer is in situ in the reactor core than when the stringer is being raised or lowered. (author)
