Description

A temporary holding system for tube bundles during their horizontal assembly in the PWR vapor generator, is proposed in order to ensure that the tubes remain in their exact position during the vapour generator fabrication, handling or transport: an annular holding device is thus arranged on the bundle extremity; it is composed of elastic envelopes filled with an inflatable substance such as gas, liquid or polymer. 6 fig
