OBTURATION DES TUBES DE FORCE DE REACTEURS NUCLEAIRES

摘要

Stopper closer the end of a force tube and is compressed against a sealing seating by autoclave effect. In the close position it is held against the seating by the reaction force of a spring device which compresses the fuel charge of the tube. Pref. the spring force is transmitted to the sealing seat via a multiplier device e.g. a lever or angle device.
